Well, it has been one month and three days since I had the hip replacement surgery. I can walk without crutches now, but I'm still limping, although I'm doing less of that as time passes. The 2006 CTS I just bought is dead. Repeat, DEAD. The motor seized on me with ZERO warning. Wish me luck, folks, because I haven't been cleared to go back to work yet, and am looking for a new motor. More details follow later today, right now I'm PISSED!!!! I worked my ASS off, maintained this car EXACTLY THE WAY I WAS SUPPOSED TO, and drove it gently. This is BULLSH*T!

This is just awful, awful luck all around. It appears Josiah had a classic 3.6 timing chain failure per this Edmunds town hall post we found (also where I found out about the engine cooling defect on the Navigator)...

"I have a 2006 CTS, and my engine blew last August on vacation. I didn't have any warning signs at all - no lights, no noises, and my car just stopped. There was a ticking noise as the engine died, and I still believe that the timing chain broke. My engine needed to be replaced because the timing chain caused the cam follower, and all the other damage to occur. I left my car in Nebraska from August 27th until November 15th, when it was finally fixed and I drove back to pick it up. It did take a long time to get GM Customer Service to make their decision, but they did a lot of checking with my dealer to see what my maintenance history was, etc. In the end, GM did agree to pay for a new engine block. If you have any hope of GM helping you in any way, you need to be very, very patient and let GM Customer service do their checking. If you need your car for transportation right away, then you'll probably be out of luck. I had another car to use for work, so I was able to wait out the decision. Sorry for your problems. I do love my CTS."

GM needs to step up to the plate on this, because this is shaping up to be even worse than the N*s defects.

I just read your text this morning. I was also going to mention the timing chain issue. I had a thread on it over in the 3.6L forum earlier this year trying to compile some info. It seems that GM fixed it for good in 2008. I believe Sal also asked them about it on his trip to Detroit and confirmed that the issue was resolved, originally caused by a supplier. Unfortunately, that leaves thousands of 3.6L VVT engines out there with faulty chains.

That's terrible, Josiah....what does a new (or used) engine run on one of those...?

How much does it cost to get the chain replaced before the engine blows? Is that what it comes down to w/CTS', like having to change the coolant as soon as you buy an old N*?

It seems when GM ventures into territory where "new to them" technology is being employed they do not have sufficient engineering expertise to design and build engines that live up to the standards of reliability (caste iron blocks and heads, lower rpm range, large cu. inch displacement instead of higher efficiency), this combined with GM's penny wise pound foolish philosophy that puts a few pennies saved ahead of reliability, and the consumer's need for lowest price possible, has been adding up to some flawed (by American standards) designs.
Many of these problem areas have been encountered by European manufacturers as they sought to increase engine efficiency and performance from small displacement engines. All this is of no solace to the consumer er stuck with the results of these errors in engineering policy and judgment.

I am very sorry to hear you have had this misfortune with you CTS, and hope you canget i fixed with the minimum of cost and hasle.

I have several friends that switched from GM to Ford and foreign cars. A good buddy of mine owned nothing but Buicks and he bought them all new. After having a terrible experience owning a Rendezvous for 5 years (not a 3800 powered one) he bought a new Ford and loves it. It just sucks.

No way they had a plastic chain... no plastic could be made into a chain that has the strength to run engine timing. There's a thread with pictures on this V6, the original chain was just a poor quality metal.

The 3800 was just too good, they had to build a shitty motor. :lol:The 3800 is an amazing motor. I JUST sold a '97 Buick Lesabre Limited with Magnaride and 194k on the clock. The car ran incredible. An older friend of mine traded this car to me as part trade for my Escort ZX2. He wanted the Escort since it was in nicer shape with only 76k miles for his wife. We agreed that I would deduct whatever the Buick brought money-wise from what I wanted for the Escort and he would owe me the rest. Now the amazing thing about this 3800 Buick is that my friend ONLY changed oil, brakes and an alternator in his 100k miles of use (he bought with 90k+ miles). I think that is impressive. Not a leak, no smoke or anything. I drove the car, even considered keeping it as a beater and I have to ask, what is the big deal about Magnaride? I know many Caddy guys always refer to it. Anyway I sold the Buick yesterday after having it advertised for maybe 6 hours! Here's a pic of that car:

08-09-11, 10:07 PM
Do not read into this too much, this is not a cut on the beloved engine. It's merely to serve as an example -

The 3800 DID suffer from a near identical problem back when it became named the 3800 (1988?) through some of the '90's. Same deal - premature tensioner wear, plastic timing gears, stretching chains. Usually it took longer though - They did fare a little better than this 3.6 and almost all broke like clockwork a little after 100k. Many times they were replaced earlier than that when a customer would complain about a CEL for the camshaft position sensor. The mechanic would find a surprise once he got the timing cover off.

This was remedied some time later.

The 2.2 4 cylinder was also a well known timing set eater for similar reasons.


The point is, (and what's disappointing is) that they've been through this before, and even fixed it, yet a similar problems still re-occur like the 3.6. I'd find it excusable if they were learning from their mistakes, but they just keep repeating them every decade. The 3800 covered the 80's, the 2.2 covered the '90's, we had the 3.6 in the 2000's - what's gonna be GM's timing chain eater this decade?

Do we have similar head gasket leaking engines across decades as well?

GM isn't the only manufacturer with this problem. Toyota's old 22R-E 4 cylinder truck motor used plastic timing chain guides that tend to break between 150-250k miles. The good thing about this though is the motor will start making a horrendous racket when one of the plastic guides break. It will still be driveable for a little while before it eats the timing chain and you get a fubar motor. Its a good bit of labor to tear the motor down, but any competent shade tree mechanic can get the job done in a day with minimal fuss, or just pay the garage $500 to put in a new "all metal" timing set.



Anyways, what year did GM redesign the timing set? I've heard that on Enclaves/Aciadias, etc that you have to drop the whole motor/tranny/front end out of them and lift the body off to do a timing chain. Ala N* headgaskets.

UPDATE: Well, I've been cleared by my doctor to go back to work. I'm a security officer at a hospital. I'm limited to the ER reception area and/or the loading dock. Neither one are big areas, but both positions are seated with enough walking mixed in to get me reacclimated to constant walking and bicycle patrol. Man, I miss both of those! I start back on Friday, so I'll have money coming in again soon. Things are looking up on at least one front.

Now, here's what happened to the CTS. I've been driving it since I bought it in April, and it's idled smoothly, accelerated smoothly, every feature has worked, no oil leaks have been seen on any spot which I have parked it. I was driving it home from a day at the pistol range with a Marine buddy of mine, and I'd dropped him off and drove towards home. On 8 August 2011, roughly 1543hrs local time, on I-20E, passing through Lithonia, I started to hear a rattle under the hood. I pulled over, intending to check underhood for any loose parts or objects. The rattling continued while in Park, so I drove it straight to Big Ten Tires in Conyers, GA. The mechanics checking my oil noticed zero oil on the dipstick. By this point, the rattle had become loud knocking. They lifted the car and found zero leakage anywhere on the oil pan or the engine. They judged the car then to need a engine rebuild, stating also that their shop was not able to do this. They filled the engine with four quarts of oil and told me that since I was only four or five miles from home, I should drive it home and park it in the garage until I was able to have the motor rebuilt. I drove home as slowly as possible, with the knocking subdued but audible due to the oil. One mile out from home on Salem Road in Covington, GA, across from an Autozone,my engine stopped running, displaying no oil warning lights, overheat warnings, or any such: only a battery charge indicator light came on. I could not crank the CTS: the ignition did not respond to my attempts, nor did the motor turn over. Due to my condition, I had to get a Newton County Sheriff's Deputy nearby to push the vehicle into an abandoned driveway. At that point, I called AT&T Roadsside Assistance, who had the CTS towed to my home.

So far, I've talked to Jesda, Austin, Ian, Rick, and others, both on CF and not. The dominant theory so far is timing chain failure, with possible engine seizure. I'm currently hunting
for gently used 3.6 motors between 2005-2007 and gathering information on the problem.

Sorry for the long and detailed post, but I'm attempting to describe thoroughly what happened. Thanks for the advice so far. I'll be making phone calls today about this problem. Opinions and advice are welcome. Thank you all for the support.

Cadillac takes a lot of unfair knocking for the 368. Everyone and their mother copied the idea, but Cadillac was the first to get it out there. The only issue was that the technology of the time just wasn't up to the demands of MDS.

The thing to remember about V8-6-4 is that it actually works, it does what it was designed to do. It's just a bit slow through it's transitions, and the change through 6 cylinder operation can be "unrefined". Also, it doesn't do much to increase mileage, which kind of defeats it's whole reason for being. All that is attributable to the electronics not being advanced enough to deal with the concept. When the system is disconnected, the engine is just a straight V8 and runs like one: smooth, quiet, and strong. Cadillac's older engines (331, 390, 472, 500, 425) were all Cadillac-designed and were all very well-regarded engines.

Now the early 4.1s were a disaster, but even then they had things squared away by 1986, and continued to use the same basic engine (bored out) through 1995. GM seems to get into the most trouble when it tries to get exotic and fancy and strays away from what it knows how to do.

Sure, my affinity for classic BMWs (up to and including E46, E39, E38 and X5) will always remain what it has been, but the truth is that in just about EVERY major product category with the exception of the C Class (which may never catch up to the 3 series), Mercedes is building a far more appealing product right now.

First, I tried to crank it today, and was successful. The motor cranks and runs, with a knocking/rattling sound that varies in intensity. I'm no mechanic, but the fact that it runs means the motor hasn't seized, right? The motor is also holding oil, although the oil smelled burnt when I checked it. Second, I had a mechanic I know do a check on the engine. He says that the sound apperas to be coming from the back and center of the engine, and that he suspects one of three problems: either a coil pack being damaged, a timing chain hitting something, or a burned cylinder. We also tested the warning lights on the dashboard, and all of them work. Theoretically, I should have gotten a warning light of some type, right? Next step is to buy an OBD scanner, and also see if any wires or fuses are unhooked. More on this later.

A hallmark of timing chain failure IS apparently a lack of any sort of warning light on the dash. I would avoid running it any more than necessary at this point, as if there is ANY chance of saving it, running it like that is only going to ensure that it's more damaged than it already is.

Dont cranck and run that engine! If I were in your shoes, I wouldn't even drive the car back home after hearing that knowkcing sound!

Al of the above was done in my garage at home. Trust me, the CTS ain't moving anywhere except by truck until I get her fixed.

The fact that the car is able to crank is giving me some hope here. I just hope there's a way out of this whole mess, and soon.

Everything will be okay. You will get the engine pulled and replace it with one from a 2011 V.

^ For the $20 grand that that would cost, he could just buy a V1 :lol:

Don't waste your time/money buying an OBD scanner, just trailer it to the local shop and pay them to do it. With a repair as intensive as this will be, I would want someone with lots of experience on it.

Back or front? The back points to something more like a cracked or loose flexplate.

Sorry to hear that you are back in the heavy pain zone with your knee, I hope you get relief from this pain soon. As far as the problems with the CTS engine, I have to agree with Chad, get the car towed to a reliable shop and have them trouble shoot the problem. Till then don't turn the engine over, or attempt to run the engine. You chances of causing additional damage are near 100%. The good news is, once you get the engine repaired you will have a car with a much more reliable engine which should provide a long and reliable transportation future!

Well, guys, the CTS is back and was repaired by the dealer with no charge to me. See my current thread for details.
