Hey all.
I'm looking to purchase a 2006 sts awd 3.6. Does anyone know of any major concerns with this particular vehicle. Such as head gasket, transmission, use of shiftronic feature. Can you use it daily and hard or will you start to have problems. I like to drive a standard car but the wife can't. Therefore this will accommodate us both. Thank you for all the replys.

Maybe you can trade the wife for a better car.

A major concern is the 3.6 itself. Timing chains are a huge problem on those engines. Plus, I've never seen one that doesn't leak oil.

Post your question in this subsection:
http://www.cadillacforums.com/forums/cadillac-sts-forum-2005-through-2012/
or ask a moderator to move this thread there. That section is specifically belongs to STS and you should be able to get good answers.

I see that truckinman has already mentioned the main problem of old V-6 STS, the timing chain! If you like to buy a Cadillac STS, I would suggest a V-8 or a newer STS with improved 3.6L engine. I am not sure exactly when they updated the design and addressed the timing chain problem, but I think it was 2007.

I'm pretty sure the direct injected 3.6 came out in the 08 mode. Gonna have to check. My 06 3.6 ran great, never leaked oil, and had pretty good pick up for a heavy car. I always worrried about the timing chain since it had 60k miles on it after reading horro stories about it.

I believe direct injection started in 07? And 2010+ is where the design improved in most cases solving the timing chain issue. There are always those people who have the v6 and never have a single issue. It's a gamble. I say, and many will agree, that the fuel economy penalty of the v8 is so small that the increased power and reliability heavily outweigh it. Plus I'd say the v8 sounds much nicer. I highly recommend going v8 instead. Also, with the v8 I personally recommend 2007+ because 2007 is when they introduced the 6 speed transmission with the v8. (2008 they put the 6 SPD with the v6). Good luck.

First V6 DI was in 2008. I would avoid any V6 prior to that year.

So.. 2008+ because they started direct injection that year. 2010+ because that direct injected v6 was redesigned to combat the timing chain issues that year.

Something to concider about the 10+ model sts though... I read an article a while back saying that 2010 is when sales really started dropping on the sts The majority of sales for the final years of the sts went to rental car services making most used cars from 10+ prior rentals. Add to that the lack of a V8 and our o.p. is back to searching for an 06-08. After everything I've done to rental cars you won't find me purchasing a prior rental :tisk:

True that. If I was not in a rush to buy a car and wanted an sts and had a decent amount of money here is exactly what I'd do. I'd hold out until a black 2010 sts v8 platinum was available. 2010 being the last year for the v8. To me that's the ultimate sweet spot for the sts.

----------

Oh and based on how I ring out rentals, yeah no prior rentals for me.

----------

AWD too since I'm from the snow belt. This is of course if the v isn't an option.

The last few years of the STS, most of the best options became available on V6 models. ACC never became available but you could get HUD which really makes the Nav come alive.

I too, recommend against buying an early V6 AWD STS.

I have a 2008 STS4 (AWD) with the 3.6 DI. My family of four took a 3400 mile road trip in it for spring break and had a blast. Mine is loaded and the 302 hp was perfect. We avg 28 to 30 on the highways. I would not hesitate on getting a v6 in a 08 up. You will love it.

Hi, I have an 05 STS V8 4 (AWD) with 71k. Just got it at the end of June. I am new to Cadillac and love the car. No issues knock on wood. It is a one owner and well taken care of. I check the oil regularly because I heard horror stories but it is good! No leakage. I love this car! Handling and horsepower! I get 16 in the city and 22 on the freeway! The little extra gas is worth the ride and class! Good luck with your research!

Had a V6 STS4 prior to the redesign. Take my advice - get the Northstar!

Great advice here. I was looking at 2007 STS AWD V6, 65K miles, driven by an older lady. Needless to say it has been very lightly driven, and at $13,000 it seems like a great deal. After reading all your coments though, I think I'm going to pass.

One year newer would be uber-tempting.

didn't the 2007 get the extended timing chain warranty?

Yes it did. I have it on mine.

Guy.Seminerio

But one year newer would get you the six speed? I'm guessing that's where he was going with that.

2007 V8 only had the 6spd.
2008+ (all) had the 6spd.

Not that I would get a V6 model but IF I was to do it it would certainly not be older than 2007 (due to warranty extension) and 2008+ would be preferred to get the 302HP DI version over the 255HP non-DI version.

2010+ for me for the improved reliability of the engine.

2010+ for me for the improved reliability of the engine.

2008 got the di v6 not 2010 there was no engine changes in 2010 and the di is just as susceptible to oil consumption and timing chain failure.

That proves there was a change in engine design on the 3.6 between 2009-2010. The forum says cts, but it also says that one result of this change was +1 mpg fuel economy on the engine.

Now look up the fuel economy ratings of the 09 and 10 sts v6.

CTS may of changed but the sts never did. Just like gen 1 srx never got the di v6.

I'm going off deductive reasoning here and I'm saying the sts changed too.

I was referring to the DI 3.6. A babied cream-puff is tempting but I'm truely a V8 sorta guy. IF I COULD be convinced, it would have to have the ponies and warranty and 6-speed all the rest... and I'm sorry I ever even mentioned it... because it wouldn't have ACC... so who cares anyway?
