The Cadillac Seville represents everything that is great in America. This car will get you noticed, and that is a good thing. If you’re the type of person who can overlook small things like a slightly cheap interior, less than excellent build quality, and the sticker price, well this is the car for you. Driving a Seville STS will have people turning heads, looking at the car over and over. It will be catching stares from people while you’re washing it in the driveway. It represents power, prestige, and the sense that you’ve made it. Sure, you can get a Lexus, but when have you ever caught yourself staring and dreaming about a Lexus? Exactly, you haven’t. The Seville is a different type of animal, and it’s the type that I love.

The specific model I’m talking about is the 2000 Seville STS. Sure, you can get the cheaper and plusher Seville SLS, but you’re basically getting a Deville in re-organized packaging. When you say, “Yeah I just picked up a Cadillac STS” people instantly know what I’m talking about. Try saying the same thing, only say Cadillac SLS. It doesn’t work; people seem confused. Still, regardless of what model you pick up, this car is an excellent value on the used car market. Take my “new” Seville STS for example. My car is a ’00 STS with 54k miles; Sterling Silver w/ Pewter interior. Fully loaded, only missing the Navigation system and sunroof. The sticker for this car brand new easily topped $52k. However, I just picked up this clean example complete with new head gaskets, water pump and motor mount for only $10,700. Yes, this 8-year-old car only cost me $10,700. Amazing, and that’s only the beginning.

Cadillac was on the emergence of a great renaissance when this car was introduced in late 1997. Not only was this car a huge improvement over the already great model it replaced, it was a huge hit with automotive journalists alike. Sales, on the other hand, dropped almost 11k units in the 1998 model year. Why you ask? Price. The base price for a ’98 SLS was almost $43,000 while the STS went for a staggering $46,000. This might sound reasonable to a Cadillac loyalist, but this car was up against some stiff competition. BMW had it’s excellent new for ’97 5-series, Lexus had its ultra refined GS400, and Mercedes had it’s super elegant E-Series. Suffice to say, sales floundered and the car went out of production in 2004 to make way for the brand new STS (minus the Seville moniker). However, there are Seville loyalists (like myself) who think this is the best modern Cadillac yet. Sure, there are a few downsides to owning this car, but they are worth accepting.

I have to say, this is the most beautiful and elegant looking sedan to ever come out of Detroit. Hell, it may be one of the best looking cars ever put into production. Sure, the new CTS and STS are impressive efforts, but none of them do it for me like the Seville STS. The car is perfectly executed, from the front grille to the rear taillights and everything in between. Cadillac was at its absolute highest from a design standpoint when this car was put into production, and there are few cars that “do it” for me like the Seville does. It turns me on, no matter where I see one or what kind of mood I’m in. I swear, I think I have a Seville monitor in my head, because I can always spot one coming down the road. The car looks stunning in Crimson Red, a lighter shade of burgundy, Sable Black, which is just badass. White Diamond is typical Cadillac, typically elegant. Sterling Silver is very clean, sophisticated, and sexy. Another of my favorite is Polo Green, an extremely rare color that looks black from a distance. The other colors are no match for the body of the Seville, and just dull the cars look. The ’98-’01 Seville SLS have a plain silver colored grille, ugly plastic molding on the bottom, and cheap wheels that look out of place on a car of this caliber. Starting in 2001, you could order a “STS Appearance Package” which added a body colored grille, 16” 7-spoke chrome wheels, body color appearance molding, among other things. This package became standard in 2003; the STS pretty much stayed the same throughout its 5-year run, with the exception of 2001 when Cadillac offered a STS Sport Package, which offered larger 17” 6 spoke wheels and other accessories. In 2002, both SLS and STS models left behind the old Cadillac logo in favor of the new “Art & Science” logo first introduced on the CTS. Other than this few appearance changes, there was nothing to distinguish the cars year to year. Only true Seville loyalists could spot these changes.

The interior of the Seville has its ups and downs, very unlike the exterior. At first glance, the car looks of the highest caliber, using exquisite leathers, high-end gauge clusters, smart controls, and beautiful wood trim. Unfortunately, this is quickly downplayed when looking closer. The headliner is made of a cheap, mouse like material found in Chevrolet’s, the plastics used on the door jams and around the console area is GM Corporate, which means of the lowest caliber. You can pull the A-pillar material off with one hand, and the weather-stripping around the door needs to be reattached on several occasions. However, none of this really matters to me. If I would have paid $53k for the car brand new, yeah I would have been disappointed with the materials. However, I’m not complaining one bit at $10k. Another thing I’m not complaining about is the features. Damn, this car really brings a new meaning to the phrase “fully loaded”. Power leather memory seats, Bose 425 watt sound system, 6-disc CD changer, and optional navigation system. Sure, most modern cars have self parking assistance, lane change warning and other useless crap you don’t need, but for a late 90’s car the Seville has everything a person would want. I’m personally the most fond of the Bose stereo, which I have still not found a suitable match for. Even the new STS with its 15-speaker system still can’t match the Seville for sound quality. This blows the competition away of the same area, with the exception being the LS400’s Nakamichi sound system. However, you might not need the Bose system at all…

…You might instead be listening to the Cadillac Northstar V8. Yes, the engine that practically saved Cadillac in the early 90’s is installed beneath the bonnet of this sexy machine. All 300 horses are driven through the front wheels, and it’s probably one of the best exhaust notes this side of a Ferrari or Porsche. The car has a typical V8 snarl when being started up, but it really shines when you floor it. You can get some serious trouble when driving this car. Most Seville’s never have the chance to be driven hard, since they are owned by old ladies driving to church. For this single reason, is why most people experience problems with the Northstar engine. The engine is extremely reliable if well maintained. The key to a strong running Northstar is changing the coolant. GM recommends the Dex-Cool get changed every 5-years/150k miles; I wouldn’t go by this, I would get it done every 3-years/48k miles. This way, you don’t have to worry about the engine blowing a head gasket. Also doing regular WOT (Wide Open Throttle; a.k.a mash that bitch to the floor) will help keep all the carbon deposits cleaned out. Do those few things (along with changing the oil of course) and you should be able to get 200k or more miles out of the Seville and its Northstar.

Ok you’ve heard me ramble on about the seductive styling, nicely laid out interior, and powerful engine, so how does it drive? Well, what do you think? It’s a Cadillac, so it has a smooth ride that soaks up the bumps like no other. It’s not super soft like the Deville, but no overly hard like the CTS. The ride motions are well controlled, and the handling is superb for such a heavy FWD sedan. It takes the corners with ease, and there is little understeer to be detected. However, if you want BMW handling this isn’t your car. The car does have a little more body roll than your average sports luxury sedan, but it isn’t anything 90% of people complain about. It feels confident throughout the ride, and the only hint of torque steer is when mashing the accelerator when exiting a corner. Overall, I give it a 7.5/10. In late 2002, Cadillac introduced the Magneride suspension for the Seville STS (and to be introduced on the 50th Anniversary Corvette) and was a marvel if anything. It uses a special fluid to adjust shock rates depending on the road. From what I have read, handling was largely improved and finding a late example ’03 STS is the best deal on the luxury market today. I haven’t had a chance to drive a Magneride equipped car, but I hope to in the near future.

The Cadillac Seville STS represents the best value on the used luxury car market today. Modern styling, loads of electronic goodies, powerful Northstar engine, great handling, and a low price makes the car the best of the best. You can find plenty of low mileage, good conditioned cars for under $10k. The ’03 STS w/ Navigation, Sunroof, and around 40k miles will set you back a very reasonable $15k. Not a bad deal for a car that stickered for near $60k when it was put to sleep. Now, I have an assignment for you: find a low mileage Lexus GS400, BMW 540i, or Mercedes E420 w/50k miles for under $14k. Might be a little harder than you think…

Great entertaining and informative review! Thanks for posting!

Sometimes (especially when I feel the need for hard acceleration) I wish I would have bought the STS over the S320. Oh well, there's always another chance! :cool2:

I'll be keeping a log in my review about my experiences with my STS. I'll probably update once a month or so, so I don't sound too repetitive. Here is my opinions after 3 days of ownership:

*The Seville is truly a highway car. In the past 3 days, I've put almost 300 miles on it and it truly soaks up the road. Engine is plenty powerful for passing grandmas, and the handling is predictable, if a bit soft. Luckily, soft is what I like best so kudos to Cadillac for creating a really great touring car.
*The interior has too many cheap pieces of trim. Even compared to my Camry, the car just has too many downfalls. My weatherstripping has been reattached several times already, and there is a persistent rattle (the old Onstar attachment thing; need to get that removed ASAP). Otherwise, a great layout. Clean and simple.
*I love the seats. Plenty comfortable for a road trip, and after 1 1/2 hours of driving I still felt relaxed. The gauges are extremely easy to read, if a bit cheesy looking (I'm comparing this to the new CTS and Escalade), the Bose stereo is amazing, and the climate control does a great job of cooling down the car.
*Fuel economy is pretty good for a large V8 car. I'm getting around 17MPG city and 22 highway. I'll be driving a lot less now I have this car, but thats fine with me.
*The styling is a huge plus. I've had more compliments on this car than I ever thought possible. Nobody believes me when I say the car is 8 years old (I can thank the original owner for keeping the car garaged! :)) and the car still looks sexy today. Personally, I prefer this body to the new Cadillac's.

Overall, I'm extremely pleased with the car. There are a few downsides, but none of them hinder what I think is a wonderful machine. My mom, grandfather, and I will be driving to the mountains soon and we've planned to take this car. I'll report back after that and see how well she does on long distance cruises (the car, not my mom!).

It's been a busy month for the Seville. I find any reason possible to drive the damn thing. It's smooth, powerful, and extremely comfortable. Compliments have been plentiful. Most people find it hard to believe the car is 8 years old; thats always a good sign. I often find people looking at the car while going down the road (or either at me. "What the hell is that kid doing driving a Cadillac? He most of stole it") The car simply shines on the open road, where it effortlessly soaks up the road. The ride is super smooth, and handling continues to impress for such a large FWD car. Gas mileage is town is 17-18, but on the highway I'm seeing 23-25MPG. Northstar is extremely powerful, and has a great sound. Interior trim is holding up well, with few rattles emitting through the cabin. Seats were comfortable on 6 hour road trip; heated seats are wonderful. Complaints are few:

1. Service Theft System randomly appears once or twice a week. Simple remedy: turn the car off and start her up again. No problems there, just a nagging issue. Nothing serious here.
2. Front end shutter under braking. This is my biggest annoyance with the car. The rotors were just resurfaced and it has pretty new brake pads, so I'm guessing another alignment is in order. I'll have dealer check this out when I take her in.
3. Steering column rattle. This turned up about 3 days ago, but it's pretty obvious. When taking the car over rough payment, the steering column makes a faint, but noticeable rattle sound. Just check out thread on Seville forum that pretty much explains my problem. I'll have the dealer lube the area first, but I'm sure that won't solve it. As long as the steering doesn't start to go screwy, I'll be fine with it.

So overall, a good first month for my Seville. There are a few little issues to work out, but nothing major. I adore my car and plan on taking her to 100k+ miles.

Update:

Took the car to the dealer today to get the oil changed and have them check the rattling noise and vibration during braking. The rear rotors were resurfaced at their expense (I only payed for labor! :D) and are smooth as silk. Finally, I don't hate stopping anymore. According to my ticket, the rattle was solved by adjusting a cable - it didn't work. At first, I thought it was gone because the steering was tighter. Alas, when I took the car down a rough road it came back. However, it's not as high pitched. I'm not going to worry about it, I know is the intermediate shaft and bearing. I'll have the parts ordered and get them to fix it when I get the oil changed next time.

The car is doing great. Planning on getting a new passenger side headlight because the old one is foggy, and the drivers side has a brand new one. Looks terrible together.

The steering wheel gets louder when its cold outside.
I got to the point where I dreaded turning the wheel in the winter ... you coud hear the
groaning sound and feel the crappy feedback.
I can't say how long the needle and grease fix lasts, because I sold my car soon after having
the inexpensive lube repair.
Having said that, its amazing how much nicer the car felt driving down the road without the
steering wheel noise.
Definitely worth the effort.

Ryan: I agree with you on the interior to a small degree. I bought one of the newer V8 Northstar emblems to put over the radio on that plastic piece. Doesn't look so bad anymore. That was the only part of the interior I hated. I like the rest. I'm thinking about getting the STS emblem from the trunk of the new STS's and putting it over next to the rightmost AC vent on that woodgrain over there.

Well it's time for my monthly update, and the car continues to impress with its excellent powertrain, super smooth ride, and comfortable interior. Gas mileage is also quite good for such a large V8 car, about 17 in mixed situation (learning more on city driving). My only issue with the car this month is a massive trunk leak I discovered about a month ago. I came back from the beach and decided to vacuum out my dirty trunk, when I discovered my spare tire well was full of water. I initially vacuumed it out and thought it had been there for a couple of years; no big deal right? Well yesterday I notice a putrid smell coming from the trunk... and I open it up to reveal the area is full of water again, though this time it was nasty, dirty water that looks like it came from our river. I figured out that it must be coming between the license plate area and the plastic cover surrounding the inside of the trunk. I'm going to get it looked at next time i take the car in for an oil change; I'm also going to switch out my old headlight with a new one eventually, its starting to look really terrible.

ryannel2003

Well the culprit of the great trunk leak mystery has been caught; turns out, the weatherstripping around the trunk lid did a really crappy job of keeping the water out. It was coming in near the trunk latch and dropping into the spare tire well. While I was at work today I asked my boss what he thought, and he said that was the best explanation. So they have the part ordered and it should be here tomorrow, and I'll get it replaced on Thursday when I head into work. They are also going to reseal near the taillights to make sure I don't have any future problems. I'm also having them look at my slightly rough idle, which I've thinking is the cracked plenum. They have that part in stock, so if that is the issue they are replacing that. Here are some pics of the really terrible looking seal on the ws:

mY 03 sts that I just bought has the same issue. I resealed around the entire weather strip with some 3M black weather strip adhesive and it has stopped about 98% of the water from coming in. I checked in my truck today as we had some very heavy rain over night and I noted a very small ( talking 1/2 a teaspoon) amount of water in the bottom of the trunk. I might just take it in to the dealer and get a new weather strip and have them seal it with some butyl rubber sealer.

ryannel2003
09-13-08, 11:35 PM
I actually got it fixed at the dealer the other day. $70 installed... and so far no water is getting into the trunk. I might get the piece that goes along the rear window fixed too just for the hell of it.

I also had them check the rough idle, but they didn't find anything. I'm thinking its the intake plenum and I'll have them check it out the next time I change the oil.

I really enjoyed this review and love your writing style.

Ok so it's that time of the month again... and no people my period doesn't come in until later on, so watch out for abnormal bitchiness. Anyways, no new problems have surfaced on my Seville this month. The trunk is now dry thanks to new weatherstripping, and everything is still running smoothly. I'm still having problems with my security light and that random noise from the speakers when I start the car... but it does it much more often when it's cold outside. I'm really beginning to narrow it down the ignition switch, but I'll cross that road when I get to it.

I let a friend of mine drive it down the road real quick, and when I asked him how he liked it, he said "It's really smooth, and has a lot more power than expected". Ha, that's what happens when you cross a luxury car with an obnoxious muscle car.

ted tcb
10-02-08, 11:56 PM
Ryan, is it possible that the noise you hear on colder mornings isn't coming
from the tiny square grille on the left side of your dash?

If so, then its a bad bearing in your asperator fan motor. That's the
tiny fan used with a temp probe to determine the ambient cabin temp
for your automatic climate control. Mine got to the point of being unbearable ... I simply stuffed some foam down the opening, careful
of the temp probe, and it stopped the buzzing noise.

How goes the steering shaft ... the lube procedure worked for me.
How is your ride ... smooth up to 80mph, or any shimmy?

One regret I had was that I couldn't hack my DIC to display actual temp readouts ... on my 97, that was an easy hack code and a welcome feature.

ryannel2003
10-03-08, 01:03 AM
I don't think so, because when I turn the radio off upon hearing the noise it stops. The noise is also occurring when the "Service Theft System" shows up on my DIC, though sometimes it does not. The best solution right now is just turning the radio off when exiting the car.

I haven't actually noticed a ton of noise coming from the steering shaft... though I'm sure it's still an issue because the steering seems a little sloppy compared to a '04 SLS I was driving the other day. Until the noise starts to really bother me, I'll leave it as is.

I did forget to mention I have the shimmy. It starts at 66-67MPH and does it all the way up to 75MPH, though 72MPH is the sweet spot where it levels out. I'll get my dealer to balance the tires at my next oil change, and that should solve it.

ted tcb
10-03-08, 11:14 AM
Best feature for me was the pride of ownership, followed by the styling, and general feeling of solidity.
After that, it was the sound system, HID's, and gorgeous 17" rims.
Hated the TPS sensors ... on hot days on the hwy, that damn "pressure too high" msg would pop up on the DIC ... giving me the disconcerting feeling that the car would blow up at any moment.:)

Unlike some here, I found my 99 and 01 had a more refined level of quality ... the newer style was quieter, plusher ride in town, and had less wind noise. I never had a single drivetrain issue with 4 STS', but had tons of nuisance issues, mostly electrical.

I hope the balance works for you. On my 99, I tried two sets of rims and tires, lots of balancing, all to no avail. On my 2001, the shimmy occured with both my stock rims/tires, and my winter steelies and snows.
I switched from Pirelli PZeros to Michelins, drove 1 hour to find the closest Hunter machine, but nothing helped.
Finally, I went to my local GM dealer, and allowed them to put old fashioned weights on the outside of my rims. It didn't totally solve the shimmy issue, but effectively eliminated 90 percent of the problem.
I'm convinced that Logan has it down pat.
As this platform ages, there is a multitude of parts that become
prone to transmitting vibrations through the wheels into the cockpit.
The only sure fire cure are new factory rims/tires, which worked for Logan ... but who knows for how long.
I test drove both of my newer STS', noticed the vibration issues, had the seller's pay for balancing, and watched the vibration worsen as the tires accumulated a few more miles. I knew I should've run away after the test drives, but the cars were soooo nice, I figured I could solve the issue where others had failed.
Sorry for the rant ... I intend to buy another STS or ETC as a toy to go with my daily drivers .... a Maxima, an 08 Mazda 3, and the dreaded Lexus ES300, which I actually really like ... I know, its similar to your old Camry, but my two boring Lexus cars (LS400) never have any issues ... none.

If your shimmy doesn't go away, try the old fashioned outside weights. It definitely made my STS more driveable at highway speeds.

ryannel2003
10-03-08, 11:34 AM
To be honest, the shimmy doesn't bother me so bad. I usually never go above 65MPH, and the one time I was on the Interstate for a long period of time it wasn't present. When I got the car, it had a slight shimmy, but nothing major. Now, it's extremely noticeable. That's what I get for not rotating the tires at my last oil change...

But my favorite thing about this car has always been the styling. I mean, nothing is as elegant and sophisticated as the Seville STS. Sure all that other fancy crap it comes with is great, but if I didn't have the leather, bose stereo, heated seats, etc. I wouldn't care. Also, I find the ride of the newer model better. It doesn't crash over bumps like mine does, and it seems to do a better job of balancing ride and handling. It also has a solidity about it that mine just doesn't have. However, the styling and interior design are no match for Seville. The Seville's are fine cars, just have to watch out for issues. Since all that headgasket nonsense already happened to my car, I expect to get many good years out of mine.

My Toyota had some issues that were extremely annoying. The bitch rattled more everyday I drove it, the sunroof was broken and was going to cost $1000 to get fixed, and the paint was becoming faded and scratched more easily than other 8 year old cars should. However, as an around town car it was great. 25MPG, decent stereo, best A/C ever put in a car. But when I drive it now, I realize how much I love my Cadillac.

ted tcb
10-03-08, 01:31 PM
Ahh, you're lucky you can keep it under 65mph.

My last STS was smooth as silk until about 68-75mph, then smoothed out again at 80mph. What a bitch when you're driving 4 hours to a wedding with a car full of family, and traffic is moving at 70mph.
My two choices were to drive in the RH lane slower than traffic, or keep it at 80 plus.
Thank God for the outside weights ... it made the car much more enjoyable, almost like a new ride.

Re your Camry, it sure looked nice in your photos.
My coworker bought a new Solara in 04, and it soon developed a few nasty rattles, which drove him nuts. He switched to a used ES300, and has driven it for 5 years on our frost heaved, pot hole'd, crappy Orillia streets. Not a rattle. Same platform, but if anyone thinks the Toyota is built to the same standards as the Lexus, then they haven't driven both vehicles through a Canadian winter.

I considered buying a used STS last week ... I must be a masochist, but I miss diagnosing and trying to fix little issues. My body guy had a customer selling his 98 STS ... it had a $4k paint job in 2006, fixing the sun damage caused by Arizona winters.
The car looked brand new, and the blue on blue colour scheme was quite dramatic. New Michelins, perfect chrome rims. I forgot how hefty everything feels in the STS ... a nice, muscular feel.

I passed because my next one pretty much has to be crimson pearl, with a solid service history. This one had 80k, avg service history, and they wanted too much at $5k. Right now, you can get into a 2002 with HID and Nav for under $7k ... I just have to be patient.

Maybe I was just lucky, but my 4 STS' all had between 80k-110k, and I never had an engine or transmission issue. Every other issue I read about occured ... you name it, I experienced it. Still, it gave the cars a personality. I might feel differently had I gone through a $3k repair, but for me, the motors were rock solid. I changed every fluid, belt, plug, fpr, etc. and never had a hiccup.
Still the best used car value on the market. Up here, we have 2004 STS' for sale. There are currently 4 for sale on Autotrader, and you can get a decent one for around $11-12 Cdn. What a bargain for a car that has worked out many of its issues.

My Camry was a great car, but it was too mundane for me. I had actually looked at a few ES300's and even a few '98-'01 GS300 and GS400's, but they're still going for $15k with low mileage. My neighbor has an '03 ES300 with 130k miles and it's rock solid. Still looks great, and not a rattle in sight.

Crimson Red is tied with Sable Black as my favorite Seville colors. Either color would've been great in my book, though I'm happy with Sterling Silver.

ted tcb
10-03-08, 04:01 PM
Funny, I never thought I would like Sterling Silver, but it may have been my favourite.
I had the 17" rims, and added the centre caps with the red crest, and limo tint.
The silver really shows off the fat wheel arches, and accentuates every curve on the body.
A very classy combination.
The car is probably too large to carry off the crimson pearl, but something about that 3 stage
paint does it for me.

An update on my Seville. I was going to order a new headlight since the old one on the passenger side is looking like hell. GMPartsDirect had a price of $363... not bad. Then I add the shipping costs and tax, came out to $453. Soo... I didn't order one. I'll try another one of those headlight kits. Or I'll get a professional to fix it.

But, I did order a new intermediate steering shaft and bearing, front door speaker, and ignition switch. My shaft has been making noises for the longest time and the steering is slightly sloppy. The front door speaker blew a few months ago and is in need of replacement (going to order subwoofer soon). Finally the I'm 85% sure the ignition switch is going bad, so while my dealer is putting all this stuff in I figured they can replace it and get that over with. Pretty happy to get started on my list. Not too much left to do! :)

tman2093
10-16-08, 10:47 PM
Ryan, you should contact Bose directly about that speaker. I recall a post from a while back about someone who got a free replacement from Bose because Bose does not want a car rolling around with a crappy sounding speakers. Search for it. I think that guy got a free subwoofer.

Damn I will have to check that out. Thanks!

ryannel2003
11-30-08, 11:01 PM
Well it's been a crazy month for the 'ol Seville. Had the intermediate shaft changed out, new Bose speaker installed, and my new ignition switch. Price for the labor came out to $300 (got a $100 discount. yay!). Unfortunately, when installing my ignition switch my tech told me my theft module was damaged, and replaced that. However, this has not solved my security light problem; I've been told it's a possible BCM problem, but I'm not throwing any more money at that issue.

An even worse issue was awakening to go to work one morning and seeing a large puddle of water on my drivers seat. After sitting at the dealer for 2 days, I had a newly resealed windshield that didn't cost me a dime. Unfortunately, it still leaks badly. At this moment, it sits at my dealer awaiting a fix (In the meantime, I've got a '08 CTS loaner so I'm not too upset). I believe a new windshield is getting installed at no cost to me, since it has always leaked. I just hope no rust found its way in there.

Nice review, I too have a 2000 STS and mine hasnt givin me a single problem (knock on wood). I love the styling of these cars and actually prefer this body style over the newer redesigned 05+ models. I added a E&G grille and the only thing I wish my 2000 had was the magne-ride suspension, HID headlights, back up sensors, and newer large screen nav system. Everything works great, sunroof is awesome, no trunk leaks, cranks instantly, and only has a very faint shimmy at 67-71mph. Im planning on getting some of the newer 17" wheels with some serious performance meat. Overall I love this car! I got the car with 60,000 miles for $4500 (gotta love recessions lol) and I couldnt be happier!!

It's been an extremely quiet month for the Seville (knock on the beautiful Zebrano wood of course). The car continues to impress with it's power, elegant bodystyle, and it's ride. I continue to enjoy driving this car, and all of my friends and family are impressed with the car. I'm still nitpicky over the crappily assembled interior, which does not fit well in a car costing $53k in 2000.

My only issues this month was a mysterious stalling, which happened a few months back in the same exact spot on the road. I've also experienced a loss of power only once, and I'm attributing both to the crankshaft position sensors, though it has thrown up no codes. My car still has the 60MPH vibration, though I'm getting new tires thrown on soon so I'll get a good road force balance and alignment to hopefully solve both. Of course, I still get a random "Service Theft System" a couple of times a day, which I attribute to a small electrical short that I'm not paying to fix. It doesn't harm the car, and restarting the car always fixes it.

Within the next month, I'm getting a new intake plenum, fuel pressure regulator, possible CKP's, a cleaned throttle body, a re-adjusted drivers door striker, new intermediate shaft bearing installed, new tires with RFB and alignment, and I'll probably go ahead and get some new spark plugs and spark plug boots thrown into the mix; i'll also get my dealer to adjust my glovebox, which is terribly misaligned. In the springtime, I plan on getting a transmission flush w/ filter, a recharged A/C. I'm getting my passenger side headlight polished professionally, getting a few dents fixed, and touching up some paint. After this, the car should be in showroom shape.

What a friggin steal! I payed $10k for my car in June '08 with 54k miles, though it had headgasket work, water crossover done, and a newly resealed bottom end among many other things. I adore the car, and much prefer my bodystyle over the '05+, though the new models drive 10x better. The only feature I wish my car had was the MagneRide, which I have yet to test on a Seville. I plan on keeping the car for another 2 1/2 years, then I'll trade up to a new STS.

Not to rub your nose in it or makie you feel bad about all the issues with yours, but here's my monthly Seville update:

Bought some gas.
Washed it.
Bought some more gas.

Been a rough one for both of us! :)

ryannel2003
01-02-09, 12:32 PM
:D I'm glad to see you finally washed the poor girl! ;)

Most of that stuff is just me being a nitpicky bastard. The only real necessary stuff is the CKP's, fuel pressure regulator, and the intake plenum. Everything else is just optional, but I'd like to have it done anyway so I can sleep better at night.

Ryan, are you sure you want to flush your transmission?
I found a simple drain, refill, and new screens safely did the job.
Do you have a budget in mind for all of this work? Sounds pricey.

ryannel2003
01-03-09, 11:44 PM
I might do that suggestion on the transmission. There have been many of them around here that have been ruined due to a service like this, though most of those come from an independent shop and not a dealer.

I don't have a budget for all of this; normally I'd say it would go for something like $1k to $1500 for everything, but since I work at my dealer I get a discount on parts and labor, so I'm guessing it will be around $700-$900 with the tires being the most expensive. I'm most likely going to wait on the spark plugs since they've only got 65k on them. My biggest concern is the fpr and the intake plenum, which is for sure causing my missing idle. I'm not too sure about the ckp right now; The other things are really a tossup, though I want to get them done and get the car as perfect as a 9 year old car can possibly be. She turns 9 years old on 1/22, and I'd like to get all of this work done for her b-day. Deserves it, that's for sure.

Hi everyone,
I have seen several mentions of the strange noises and the "service theft system" light. I live in Wisconsin and every time it gets below freezing my car makes a terrible noise when I start it, like a "wha..wha...wha....wha" noise that comes from what appears to be somewhere behind the dash near the far left corner of the windshield. It sounds like someone is slowly strangling the alarm system but it is clearly louder on the inside of the car. This is also accompanied by the "service theft system" message and lately also the security light. It only does this for 20 seconds to a couple minutes depending on how cold it is and it only seems to do it on the first start of the day. The alarm system still seems to function properly but this is driving me crazy. Any ideas??? or should I just try to ignore the noise and my boyfriend referring to my sweet ride as a "rickety old Cadillac"??
Also, if there is a better place for this post, let me know...and thanks for any help you can give me.:banghead:

luvmy, Do a search for "aspirator" and "cabin air temperature sensor".
You're looking for the procedure to R&R the sensor and tiny muffin fan behind the 1" square grille just left of the steering column. You go in through the panel at the left (door) end of the instrument panel, the one with the round window duct sealer which mates with the door duct. Listen at the grille during cold start.

If that's not the problem, then look for the A.I.R. secondary injection pump, located in the l/f fenderwell, used to light off the cat on cold start.

Move this up to Seville..............fairly common problem.

:welcome: to the forums!

It's best to post this in the Seville/Eldorado forum which has more traffic. The sound coming from your dash could be the aspirator fan, which over time starts making lots of noise and needs replacement. A new one cost $30 and a search around the site will show how to replace it. Mine makes a similar noise, but it doesn't bother me enough to replace it now.

As for the Service Theft, I'm not sure where you would start. The day after I bought my car in June it randomly lit up on the dash, and my dealer and I are stumped as to what it could be. One tech suggested the BCM, but if that were so the other functions running through it would most likely be fizzling as well. My car might have a slight electrical short causing the Theft message, but I'm not dumping any more money into it. You're message could be something as simple as the theft module, but I'd post in the other forum to get more information.

Luvmy, I did a cheap fix on my aspirator fan.
I took off the tiny grill, moved the temp probe wire to the side with needlenose pliars, and stuffed
some insulation down to the fan.
Got me through one cold winter without that grinding noise.
The permanent fix is what Submariner says ... replace the fan, because the bearing goes bad.
Good luck, enjoy your ride.

I'm keeping this thread around as kind of a one year long term test, to see how a Seville ages after it's already 8 years broken in. So far at the almost 7 month mark, the car has given me no motor trouble to speak of. My problems have been with the accessories, mainly the still shining "Service Theft" message, the sometimes bipolar radio, and the aspirator fan which is on it's way out.

Today I took the car in for it's most comprehensive service yet, getting an oil change, new crankshaft sensors, a new intake plenum, a glovebox and drivers door adjustment and few things I'm forgetting. I'm $500 poorer, buy my slightly "off" idle is much improved, though it's still not perfect. With a tuneup coming soon, I expect that to be fixed completely soon. My passenger headlight is still in bad shape, and very soon I will get that fixed, along with some touchup and a few dents that are getting on my nerves. I get new tires next week, most likely cheaper Uniroyal's along with a RFB and alignment. My next service will include the aftermentioned spark plugs and boots, a tranny flush, and a/c service. Other than my gripes, the car is still impressive after 7 months and 11k miles of service. I still stare at it when walking away, which causes most people to look in confusion. They don't get it.

It's been pretty quiet here in the world of Seville, at least until something goes south next week.

My slightly off idle I reported last time... turns out to be a poor camshaft design by GM that effects some early 2000-2001 model year Northstar's. The original owners never gotten it taken care of, and I'm going to continue that trend. It's not worth spending that kinda of money on a 9 year old car. I did get new spark plugs installed and have been using premium gas, so that helps it a little bit.

After my unfortunate blowout, I finally got new tires. Cheapy 225 Uniroyal's (I'm not made of money here). I'm not crazy about them at all. They don't handle well, and make more noise than the Michelin's did (you pay for quality). They ride nice, and 90% of my 65-75MPH vibration is gone. My brakes still vibrate terribly. Guess they need to be resurfaced... again. I'll cross that bridge when the time comes.

The outside of the car looks better than ever! Finally got that foggy headlight cleared up, though it still doesn't look as good as the drivers side. Oh well, not worth spending $500 for a new one. Got a few of my spots touched up with GM touch-up paint. Has some dents on the roof but otherwise, the outside is immaculate.

My problems with the car continue to be the "Service Theft System", a noisy aspirator fan, warped dashpad, and noisy passenger side strut. The fronts will need replacement soon, though I'm hoping I can go another 10k miles before replacing. I'm going with Arnott.

The Cadillac Seville represents everything that is great in America. This car will get you noticed, and that is a good thing. If you’re the type of person who can overlook small things like a slightly cheap interior, less than excellent build quality, and the sticker price, well this is the car for you. Driving a Seville STS will have people turning heads, looking at the car over and over. It will be catching stares from people while you’re washing it in the driveway. It represents power, prestige, and the sense that you’ve made it. Sure, you can get a Lexus, but when have you ever caught yourself staring and dreaming about a Lexus? Exactly, you haven’t. The Seville is a different type of animal, and it’s the type that I love.

The specific model I’m talking about is the 2000 Seville STS. Sure, you can get the cheaper and plusher Seville SLS, but you’re basically getting a Deville in re-organized packaging. When you say, “Yeah I just picked up a Cadillac STS” people instantly know what I’m talking about. Try saying the same thing, only say Cadillac SLS. It doesn’t work; people seem confused. Still, regardless of what model you pick up, this car is an excellent value on the used car market. Take my “new” Seville STS for example. My car is a ’00 STS with 54k miles; Sterling Silver w/ Pewter interior. Fully loaded, only missing the Navigation system and sunroof. The sticker for this car brand new easily topped $52k. However, I just picked up this clean example complete with new head gaskets, water pump and motor mount for only $10,700. Yes, this 8-year-old car only cost me $10,700. Amazing, and that’s only the beginning.

Cadillac was on the emergence of a great renaissance when this car was introduced in late 1997. Not only was this car a huge improvement over the already great model it replaced, it was a huge hit with automotive journalists alike. Sales, on the other hand, dropped almost 11k units in the 1998 model year. Why you ask? Price. The base price for a ’98 SLS was almost $43,000 while the STS went for a staggering $46,000. This might sound reasonable to a Cadillac loyalist, but this car was up against some stiff competition. BMW had it’s excellent new for ’97 5-series, Lexus had its ultra refined GS400, and Mercedes had it’s super elegant E-Series. Suffice to say, sales floundered and the car went out of production in 2004 to make way for the brand new STS (minus the Seville moniker). However, there are Seville loyalists (like myself) who think this is the best modern Cadillac yet. Sure, there are a few downsides to owning this car, but they are worth accepting.

I have to say, this is the most beautiful and elegant looking sedan to ever come out of Detroit. Hell, it may be one of the best looking cars ever put into production. Sure, the new CTS and STS are impressive efforts, but none of them do it for me like the Seville STS. The car is perfectly executed, from the front grille to the rear taillights and everything in between. Cadillac was at its absolute highest from a design standpoint when this car was put into production, and there are few cars that “do it” for me like the Seville does. It turns me on, no matter where I see one or what kind of mood I’m in. I swear, I think I have a Seville monitor in my head, because I can always spot one coming down the road. The car looks stunning in Crimson Red, a lighter shade of burgundy, Sable Black, which is just badass. White Diamond is typical Cadillac, typically elegant. Sterling Silver is very clean, sophisticated, and sexy. Another of my favorite is Polo Green, an extremely rare color that looks black from a distance. The other colors are no match for the body of the Seville, and just dull the cars look. The ’98-’01 Seville SLS have a plain silver colored grille, ugly plastic molding on the bottom, and cheap wheels that look out of place on a car of this caliber. Starting in 2001, you could order a “STS Appearance Package” which added a body colored grille, 16” 7-spoke chrome wheels, body color appearance molding, among other things. This package became standard in 2003; the STS pretty much stayed the same throughout its 5-year run, with the exception of 2001 when Cadillac offered a STS Sport Package, which offered larger 17” 6 spoke wheels and other accessories. In 2002, both SLS and STS models left behind the old Cadillac logo in favor of the new “Art & Science” logo first introduced on the CTS. Other than this few appearance changes, there was nothing to distinguish the cars year to year. Only true Seville loyalists could spot these changes.

The interior of the Seville has its ups and downs, very unlike the exterior. At first glance, the car looks of the highest caliber, using exquisite leathers, high-end gauge clusters, smart controls, and beautiful wood trim. Unfortunately, this is quickly downplayed when looking closer. The headliner is made of a cheap, mouse like material found in Chevrolet’s, the plastics used on the door jams and around the console area is GM Corporate, which means of the lowest caliber. You can pull the A-pillar material off with one hand, and the weather-stripping around the door needs to be reattached on several occasions. However, none of this really matters to me. If I would have paid $53k for the car brand new, yeah I would have been disappointed with the materials. However, I’m not complaining one bit at $10k. Another thing I’m not complaining about is the features. Damn, this car really brings a new meaning to the phrase “fully loaded”. Power leather memory seats, Bose 425 watt sound system, 6-disc CD changer, and optional navigation system. Sure, most modern cars have self parking assistance, lane change warning and other useless crap you don’t need, but for a late 90’s car the Seville has everything a person would want. I’m personally the most fond of the Bose stereo, which I have still not found a suitable match for. Even the new STS with its 15-speaker system still can’t match the Seville for sound quality. This blows the competition away of the same area, with the exception being the LS400’s Nakamichi sound system. However, you might not need the Bose system at all…

…You might instead be listening to the Cadillac Northstar V8. Yes, the engine that practically saved Cadillac in the early 90’s is installed beneath the bonnet of this sexy machine. All 300 horses are driven through the front wheels, and it’s probably one of the best exhaust notes this side of a Ferrari or Porsche. The car has a typical V8 snarl when being started up, but it really shines when you floor it. You can get some serious trouble when driving this car. Most Seville’s never have the chance to be driven hard, since they are owned by old ladies driving to church. For this single reason, is why most people experience problems with the Northstar engine. The engine is extremely reliable if well maintained. The key to a strong running Northstar is changing the coolant. GM recommends the Dex-Cool get changed every 5-years/150k miles; I wouldn’t go by this, I would get it done every 3-years/48k miles. This way, you don’t have to worry about the engine blowing a head gasket. Also doing regular WOT (Wide Open Throttle; a.k.a mash that bitch to the floor) will help keep all the carbon deposits cleaned out. Do those few things (along with changing the oil of course) and you should be able to get 200k or more miles out of the Seville and its Northstar.

Ok you’ve heard me ramble on about the seductive styling, nicely laid out interior, and powerful engine, so how does it drive? Well, what do you think? It’s a Cadillac, so it has a smooth ride that soaks up the bumps like no other. It’s not super soft like the Deville, but no overly hard like the CTS. The ride motions are well controlled, and the handling is superb for such a heavy FWD sedan. It takes the corners with ease, and there is little understeer to be detected. However, if you want BMW handling this isn’t your car. The car does have a little more body roll than your average sports luxury sedan, but it isn’t anything 90% of people complain about. It feels confident throughout the ride, and the only hint of torque steer is when mashing the accelerator when exiting a corner. Overall, I give it a 7.5/10. In late 2002, Cadillac introduced the Magneride suspension for the Seville STS (and to be introduced on the 50th Anniversary Corvette) and was a marvel if anything. It uses a special fluid to adjust shock rates depending on the road. From what I have read, handling was largely improved and finding a late example ’03 STS is the best deal on the luxury market today. I haven’t had a chance to drive a Magneride equipped car, but I hope to in the near future.

The Cadillac Seville STS represents the best value on the used luxury car market today. Modern styling, loads of electronic goodies, powerful Northstar engine, great handling, and a low price makes the car the best of the best. You can find plenty of low mileage, good conditioned cars for under $10k. The ’03 STS w/ Navigation, Sunroof, and around 40k miles will set you back a very reasonable $15k. Not a bad deal for a car that stickered for near $60k when it was put to sleep. Now, I have an assignment for you: find a low mileage Lexus GS400, BMW 540i, or Mercedes E420 w/50k miles for under $14k. Might be a little harder than you think…

It's been another month since I have posted about my Seville and nothing else has changed. I'm still dealing dealing with my more annoying than ever "Service Theft System" message on the DIC. I'm to the point now where I'm just ignoring it, because I'm sure it's a very expensive fix that isn't worth it on a $6k car.

My brakes were vibrating very badly so I finally took it in to repair them along with the inspection sticker. Turns out I had less than 2/32 on the rear pads and my fronts were warped. Got the whole shebang done for around $190. Not bad at all; also got them turned just to make sure I don't have any more problems. Brakes are smoother than glass; i've had the car since June 30th 2008 and they have never been this great.

My noisy "strut" has turned out to be the swaybar bushings; eventually I will get them replaced. For now, I'm going to ignore the squeeking. Best way is to turn up the radio and you can't hear a thing. :)

Still adore the car very much, though if I did it all over again I would definitely purchase a MagneRide '02-'03 STS in Blue Onyx, Black, White Diamond, or Crimson Red. Not that I don't love Sterling, but those 4 colors are my Top 4 favorite (in the correct order).

my STS is doing the Service Theft System as well. i bought the car used and had a 2nd key added by the dealer. still did it after they rekeyed everything. its just a minor annoyance and doesnt reduce my ability to drive the car so i chose to igmore it.

thank you for keeping a log of your car, its fun to read. :)

For the first time since I've owned the car this month has produced nothing unusual, and I'm preying that I have tackled the cars issues for the most part and don't have to do anything but required maintenance.

My taillights were filling with water pretty badly so they drilled two holes on the bottom of the lenses to solve the problem. It actually isn't the seal, but instead a crack in the lense. It has started getting bigger so if it ever gets to a really bad point, I'll buy a used assembly. They aren't too expensive. My brakes have recently started to make a rubbing noise that only occurs once a day. Worst case scenario: the calipers are slightly sticky causing the noise; I'm getting my oil changed within the next week so I'll report back with any new findings.

Today also marks my 10th month with the car. Started with 54306, now have close to 71k miles! I've been driving the Camry more lately, otherwise I'd be much closer to 74k.

This will be the quietest month to date with my Seville. Nothing unusual or strange to report here; brakes still sometimes make a rubbing noise, but a few hard stops from 70 seemed to have quieted them down. My issues with the car that have been documented before are:

*Service Theft (since it's been hot here, only happening 1 or 2 times a week)
*Taillight condensation (well document on Seville's)
*Possibly loose or broken motor mount (all those damn WOT)
*Still foggy headlight (not a huge deal, the car is 9 1/2 years old)
*Warped dashpad (getting to that sometime this summer)

Other than that the car is still a pleasure to drive with a clean design that doesn't look dated. Next month will be my official year with the car and at that time I'll summarize all costs that have accumulated and finish up my reporting on my one year with the car. Until next time...

Quick update on my brakes. They have gotten really bad lately so I took it to my dealer today to get it checked out (I took it up there late; around 3) and they didn't have a chance to work on it because the damn things were so hot they couldn't touch them! Oh well, I had the chance to be in a rental '08 CTS for an hour or two.

It probably needs new pads and to be resurfaced. I rode around with warped rotors for so long it most likely prematurely killed my pads. No biggie, I'll get them fixed and be good. Hopefully.

One year ago I acquired a sterling 2000 Cadillac Seville STS after a exhausting 1 1/2 yr search. While I had found a few good candidates along the way, they were either too expensive or had too many miles; This one came at the perfect time. This car had a good service background: a 1 owner, doctors car that had been traded in on a CPO '08 STS. This car did need some attention though, as the HG's were gone and it needed a water crossover pipe. So along with those repairs it got a new motor mount, was completely resealed, and had some other tidbits done before purchase. I purchased this car on June 26th, 2008 with 54306 miles. While I've had some issues with my car, it doesn't take away from the overall Seville experience: a sleek, stylish, powerful, well controlled car that just never got the attention of praise it deserved.

The motor on my car was actually one of the high points of owning this car, as it never gave me an ounce of trouble besides the all too common Crankshaft Position Sensors and a slightly "off" idle that was traced to the camshafts. The latter doesn't bother me too bad, and it is non-existent with premium fuel. I've put 20k on the motor so far and I don't expect it to give me any issues since it was practically rebuilt before I bought the car.

The suspension on my car has also held up well. I had what I thought was a failing strut for quite awhile; when going over speed bumps the front end squeeked terribly. However, when I had my brakes done I described my problem to my tech and he suggested greasing the bushings. I haven't heard a sound from the car since. Thank god, I was already saving up for new struts. The handling has suffered a bit thanks my idiotic attempt to save money and putting on 225 Uniroyal tires that ride great, but offer little to no handling prowess. The car handled so much better with the 235 Michelin Symmtery's, and that's what I'll be putting on the car again. The typical G-body shimmy is about 80% contained on my car; it starts at 68mph and ends at about 76mph. I really need to get the car RFB again, but that will be in the future. It doesn't help that I have a broken front motor mount either. They hold up about as good as a stick of butter.

Cosmetically (interior/exterior) the car is great. It sure doesn't look like a 9 year old car (more like 4 or 5). The paint is still shiny and looks amazing after many coats of wax. I do have an area on the drivers door where the clearcoat is coming off just slightly, but until it gets worse it doesn't bother me one bit. I do have a really ugly passenger side headlight, that after many attempts of cleaning, still looks terrible. I've decided one day I'll purchase a brand new headlight and sell the one I have now. I have 4 dents in my roof that came from... well I don't know where they came from. I'm getting them fixed soon. My taillights started to take on condensation but after drilling holes it looks fine. Turns out I have two small hairline cracks in my lense, letting in water. One day I'll fix it, but for now I'm not too worried.

Inside, I have the typical warped dashpad. My best friend and I are tackling that project sometime next week in an attempt to save $400 on a brand new one that will just do the same thing after 2-3 years of having the hot NC sun hit it. The leather, while cracked, still has held up amazingly well. The drivers side has the most wear (obviously) but it doesn't look bad. Honestly, cracking leather doesn't bother me. As long as it isn't ripped I don't really care. The wood trim still looks great, though it has scratches around the shifter (it's common, so I don't worry about it). My latch on my center console broke off in my hand a few months ago, but it was already on the way out; the passenger side heated seat element is no longer operational. I'm not a passenger in my car, so I could really care less. Everything else inside my Seville is immaculate, and people cannot believe how I keep the car so damn clean. I'm so OCD about my interior I usually just don't have people ride in the car.

In a nutshell, I have enjoyed Cadillac's Seville STS very, very much. It's just a superb vehicle with a troublesome motor and shoddily built interior. It's unfortunate, because the rest of the car is great.

P.S., when I get home I'm going to add up all my costs I have built up in the past year. I calculated about $2500, but some of that was just my obsessiveness to have a perfect car.

Thanks for reading.

ryan, your headlight can be polished to near new. use the meguire's headlight restorer. its $20 and it DOES work. i recommend useing a power drill as a portable will be eating batteries quickly. you will probably spend about 3-4 hours on it total. mine were pretty bad and ended up looking nearly new. it improved light brightness quite a bit. for application, i just polished the light in 1 hour increments and cleaned it after each session.

I just recently bought, Aug 4th to be exact, a 2000 Cadillac STS in forest green color. I had been searching for a DTS but decided to include the STS in my searches. I currently own a 92' Seville. It was time for me to get something newer. A business in the area advertises they will search for the car for you. They go to auctions. He picked up this car for $3495 plus his 10% fee, came to $3850 that I paid him.

I drove it home, which is a 40 minute drive, only to have the Service Engine Soon light come on. Then the car started to get really hot. The message on the dash said Engine Hot-turn AC off. I made it home, holding my breath the whole way. I added some antifreeze and water to it and ran the service codes. It came up with PCM P1133 which is Heated Oxygen Sensor H02S Insufficient Switching Bank 1 Sensor 1. Since adding the coolant, I haven't had any heat issues but I also haven't needed to be on the highway or turn the air on. It goes into the shop Monday with a list for the mechanic to look at and see what all it needs.

I noticed that I there is a lot of rust on both back doors, covered with paint. I put gas in it the other day and also noticed the gas opening, after taking the cap off, is all rusted! I had found some forums on the web talking about this rust issue and the water drainage problem. I am going to have those checked out as well. I printed out all the forums to give to the mechanic.

At least with getting the car as reasonable as I did, I have some cushion to put in a $1000 or more if it needs it. So far I just love this car!!! I am keeping my old one till all the issues are fixed on my new one. It's pretty cool having two Cadillac's in my garage, both paid for...and I'm a single mom.....:)

I've enjoyed my Seville very much, even though it's showing it's age in certain areas. I've got a loaner '08 CTS weekend (damn tire is leaking air and my dealer isn't open for service on Saturday) and I still don't like it as much as my 'ol Seville.

I would be EXTREMELY weary about the motor running hot though. That sounds just like the beginning of the common Northstar headgasket problem. Make sure to ask your mechanic to do a block test to check, and if it comes up positive be prepared to spend alot more than $1000 to get it fixed. However if you live near or close to Ontario, you can take the car up to Jake (look up 97EldoCoupe on the forums) and get it fixed for around $2000. That is quite a bit cheaper than paying $4000 to get it done at a dealership. That could explain why you got the car for so cheap, because I still 2000 STS's with 100k +/- going for around $5-6k in good shape.

Good luck and hopefully it's something alot less expensive than a HG repair. If it turns out to be, I'd fix it and you should be able to get another 100k+ out of your motor.

Hi all...This is my first time here at this forum. I currently have 2 Cadillacs in my stable, one 1972 Eldorado Conv and a 2000 STS. I purchased my STS 4.5 years ago with 25K on it. It's original sticker was $55.1, and I paid $18,000 for it. Today it's about 10 years old with 87k on it. It's a real beauty in Crimson Red with factory chrome wheels. Frankly, it's been a dream car, one owner, 5 yrs old at purchase with only 25K. I really fell into this one and I've truely enjoyed almost 5 years of happy driving. Car has every option but backing sensors and Nav.

Problems...many seem to be ones you all have found, and I wince everytime I go near the dealer. Other than oil changes, I never get out of there for under $500.00. Major problems...Driver seat heater element been replaced 3 times, crank shaft sensor...only major problems. Current problem is rear leveling system. Warning came on last year for suspension system. Turned out to be leveling valve. Had it replaced, but since then rear of car is jacked up like hot rod. Dealer says system is operating correctly, but even my headlights are pointed down in front of the car... Any Suggestions???

Update on my 2000 STS. It still overheats ONLY when the AC or the heater is on. I have had two block tests done, flushed the radiator and added the sealant tabs, the fans are all working like they are supposed to. Had the purge valve checked to see it if it was blocked and it's not. I never have a problem with overheat as long as I don't turn on the heat or the AC. It goes in to a different mechanic on Tuesday to be looked at. I have searched and searched the internet for this problem and can't find anything. Thoughts or suggestions? Besides trade it in...

Just a suggestion, because you sound frustrated and ready to dump your car.
Not may people read this subforum ... why not post your query in the Northstar technical forum, where the experts will chime in?
Even the Seville forum is visited far more frequently than this area.

Best of luck, I hope its a simple fix.

You'll have much, much better luck posting in the Seville forum where the Seville experts (mainly Sub and Ranger) will be there to help you out as much as they possibly can.

It's been awhile since i've updated anything here, so I'll just do a quick one. The car now had 78k miles and it's been doing great lately. A couple of months ago my best friend's sister backed into the car and cracked the headlight and scuffed up the bumper but a call to her insurance company and a week in the body shop has her looking like new! I've also re-dyed my seats (I don't know if I mentioned this in here before) where the dye was coming off and they look great! The only issue I continue to deal with is the "Service Theft" message. I recently tried taking some rubbing alcohol and putting it on the key and seeing if that cleans up the contacts inside the switch. It helped, but it still randomly shows up. I did notice alot of black gunk on the key so I'm thinking a few more passes and it should clear the message for good. I'm going to finally get around to fixing my dented roof one day, along with putting in a new passenger tailight and trunk panel. Tint and a strut tower brace will follow along soon as well.

Ryan, its been quite awhile since you've posted any updates on your STS.

How have the past few month of ownership been?

Still running smooth?

The past couple of months have been tough on the Seville. It has needed quite alot of expensive work done and it's getting to the point where I can't afford to own it anymore with me going to school and working part time.

Around October of last year my A/C started acting funny. It would loose Freon at rate of a 1lb every couple of months. The driver's side would start to become warm and gradually the A/C just didn't cool the car at all. I had it at the dealership several times for this problem and it was finally fixed last week. The A/C line that goes from the compressor to the accumulator was leaking freon. My tech thought it was going to be the evaporator so I was lucky to escape that. However while he was working on the A/C I was informed that one of my radiator side tanks had a small crack in and it had started leaking coolant. Well that was unexpected but $500 later I had a whole new radiator. My left CV joint was busted and it's going to need replacing in the near future. I had two blown Bose speakers that I replaced as well. My motor mount busted in early January and was replaced along with two new front tires.

All in all I have spent around $1500 in the past 3 months on the car and it's only March. At this point I have the car listed for sale because I'm worried about what is going to happen next. I haven't had many calls on it but I hopefully somebody would like to own a really clean Cadillac. If I get lowballed or don't get what I ask, I'm going to keep it and just see what else comes along. If anybody is interested in the car, PM me. I'm trying to get $6750 for it but I am open for offers. 85k miles. All original records and always serviced at Cadillac dealer. I'm the 2nd owner of it. Sterling Silver w/ Pewter leather interior. Thanks.

I traded in my POS 2000 STS the end of January. Got to where it wouldn't even start. The battery was fine, I think it was in the ignition switch. It also needed all new brakes, rotors, etc. It started to have a leak somewhere. I said screw it. Traded it in the end of January and bought a Buick!! Good luck to you on selling yours.

Ryan, if your STS is pretty much sorted out by now, you may consider riding it out.
Many people on this very forum have a rash of expensive repairs, and then go for long periods
of time with just gas and oil, nothing more.
It would be a shame if someone picked up your car, then drove it free of repairs thanks to your service diligence.

I probably am going to ride it out because if you think about it... for the price you pay for one of these what else could you find with 1/2 the luxury, comfort, power, or style? Not a damn thing. At this point the car is behaving... I do need a CV shaft and I have a annoying, but not killer clunk/rattle coming from the from of the car that I need to get looked at but otherwise a good running Cadillac.

Plus I haven't had any calls on the car and I figure it's not a hot sell because these cars are on the market for next to nothing and there are plenty to choose from. I doubt somebody would find one as clean as mine with the service history but you really couldn't ask for a cleaner car. If it starts giving me more expensive problems I'm going to have to let it go.

Yikes... I have been dithering between another LS400 or STS lately and was pretty close to pulling the trigger on a pristine 2003 STS at a dealer in Georgia if I could score it for 7k. Its sable black and still has some of the 100k warranty left somehow.

However, after reading through all 4 pages of this thread, IF I end up getting anything (and its likely I won't as the Jeep is fine) I think I'm squarely in the LS400 camp again. It is amazing how much car those are for such a small amount of money... just like the Seville. As an auto enthusiast the very principle of a Lexus makes me sick, but the LS400 in particular from 1998-2000 is an absolutely amazing engineering marvel... even more-so as time goes on than the years that came after. Lexus' "W140" if you will.

A few months ago I just about sold the Seville. I was sick of dealing with the constant worry of a looming $500 repair, the annoying rattles that emitted through the cabin, the suspension that started getting soft and weak, and the motor that seemed like it was going to break any day.

Then I realized I'm driving a 10 1/2 year old luxury sedan... it's not perfect. It has its flaws but they aren't terrible. The car is still (in my eyes) absolutely stunning. The paint still gleams like showroom new; the interior still smells factory fresh and it still drives smooth and comfortably. I'm completely OCD about the car, but I've really toned that down in the past few months. Since getting all of those expensive repairs done this past March the car hasn't been giving me much trouble at all. The only issue I did have was the motor mount that completely broke in half, no thanks to my lead foot. Pissed that I was faced with another $200 repair bill, I rushed the car on craigslist and had a few people interested with the price set at $5250. I could have sold the car and had cash in my hand, but once I started rationally thinking about it I knew I was making a mistake. I know that I will never be satisfied to drive anything else but a Cadillac for the rest of my life, and I quickly took the car off and continued to drive it. Turns out, my motor mount was covered under warranty and I didn't pay a cent.

The car continues to amaze me with it's cleanly sculpted body that never ages, an interior that still looks fresh and is comfortable yet ergonomic, and a powerplant that thrills while providing great gas mileage and a exhaust note that would rival any sports car. I love my Seville STS very much, and it has provided me with 2 years of great service. I'm not gonna lie... I've driven the car hard. It has had a few hiccups along the way yet it never ceases to give up. It still needs a few bits and pieces but otherwise I'm happy with how my ownership has turned out with it so far. When it dies, I'm going to find the lowest mileage '03 STS I can find. The newer RWD STS doesn't give me a similar satisfaction that Seville provides. The Seville STS is the perfect Cadillac, and the perfect car for me.

Haven't updated this thread in nearly 4 months so I'm gonna give a quick update on the car. It's definitely been behaving itself within the last few months; nothing really new or interesting has gone wrong. Within the last few months my 3rd LED brake light has nearly gone out however. Only a small segment is left that works; no biggie, I found a nice replacement from an '02 SLS on eBay for $85 and I plan on picking that up soon. Car is gonna need a new set of tires soon, and I asked my parents to get me a set of Michelin Primacy MXV4's to cure the vibrations and improve the handling. The car is closing in on 100k miles and you can start to feel things getting "worn out". I still need to replace the CV joint but it's only started clicking a little bit. Brakes and rotors will need to be done soon as well, and I would love to replace the control arms and start getting a few suspension parts out of the way. I'm gonna keep these struts going as long as possible before I replace them, and when I do so I will go the active Monroe route.

The car is still as comfortable, powerful, elegant, cleanly sculpted and thrilling as the day I bought it 2 1/2 years ago. It pisses me off, but ehh it's like having a wife. On the days it doesn't bitch, it's a truly great automobile.

My daily routine is pretty much the same. Get out of bed, throw some clothes on, brush my teeth, put my contacts in, and head out the door. I don't know why but everytime I walk out the door and see the STS, it just puts this smile on my face. Even after nearly 3 years of owning the car, I don't grow tired of it. Maybe that's because it's such a good looking car. Maybe it's because I'm constantly worried about what might go wrong next, but one thing is for sure: I really do love this car.

In June it will have been 3 years since I owned the car, and to be honest it has been behaving itself very nicely since I sunk $2000 into the car last year. Of course the car isn't perfect and needs a good $2000 worth of work to make it great, but for right now it's doing a good job. As of today she is off the road, but not for long. Coming back home last night I heard this terrible rubbing noise coming from the front... but I knew my problem. The brake pads were completely worn down; now I know this car is intelligent enough to tell me I need to change my brake pads, but I've been ignoring the fact it has to be done. In fact, I've been ignoring the car for the past 6 months. Of course I change my oil and rotate my tires, but otherwise the car has been neglected. The front windshield has a large crack I have yet to take care of, the rear suspension is sitting a little bit low and needs new air shocks, and the brakes have been bad for 6 months. However, I realized that once I stopped trying to make this damn car perfect... it's been great.

Once I got home last night it was too late the check the rotors, but this morning I got a glimpse of them... and they are toast. To be completely honest, they are 11 years old and they needed replacement anyway so I'm not too upset about the loss. Since the car is not suitable to drive, I decided to take this time and do some TLC. The dash pad has come out and is going to be re-glued. I tackled this project around 2 years ago but I didn't put glue all the way around the edges and the places where I didn't have been coming up for 6 months. I'm also going to take this time and steam clean the carpet and condition the seats. They aren't in bad shape, but the seats could really use a good clean, along with the carpet. Once that's done (along with the brakes and dash) i'm going to start saving up for the 3rd LED brake light, which shouldn't be to difficult to find and replace.

However this summer I'm going to start doing more drastic things with the car, starting in the rear. I'm going to find a new "used" low mileage set of air shocks and have those installed, along with new rear air lines. Once that's finished, I'm going to move up front and buy some Monroe active suspension parts and control arms. If I have to replace tie-rod's I'll do that as well. The windshield will also be replaced around this time, and once all of that is done I plan on driving it and being happy. It won't be perfect, but it will most likely have 110k miles on it by summer and I plan on making the cleanest, best running 100k+ mile Seville on the road.

Plus, it makes me smile when I walk out the door. I can't say that about any other car I've come in contact with.

As I approach the 3 1/2 year mark with my Seville, things seem to be quite good to be honest. Sure the car isn't perfect and at this point it never will be but my journey with the Seville has been a good one compared to some of the horror stories I have read about these vehicles. In the past year I've had new Michelin HydroEdge tires installed, the oil changed a few times, a new cv axle installed, new air filter, a throttle body and fuel injector cleaning done... and that's it. The car has behaved itself quite well over the past 6 months which is awesome. As a college student this is not the ideal car to be driving and at some point I'm going to have to spend some money on it, but otherwise it's getting me from Point A to Point B in comfort and without any fault. I have a box with two control arms ready to be installed, and I'm ordering a new transmission mount and 3rd brake light this week. On Thursday I'm having the front bumper painted due to a previously bad job, and sometime soon I'd love to be able to get new shocks and struts installed, even though the old ones aren't too bad (the rears do leak a little though).
