    2006 STS timing chain issue

    Hey everyone,

    I graduated college just a few months ago and immediately got my first job (yay) so I went out looking for my first big boy car. I browsed dealers and classifieds and my eyes caught an 06 cadillac STS. The car was immaculate...flawless inside and out. I took it to my mechanic and upon further review everything came out just fine. I went ahead and purchased the vehicle with just under 75k miles. I was, and still am, absolutely in love with this car. I went so far as to convince my brother-in-law to lease his next car from GM because I wanted to start my loyalty to them from this car on-wards. Now comes the sad part...after a few months, the check engine light went on and I took it into my local cadillac dealer to get it checked out. $150 fee later, I was told the timing chain needed to be replaced. At first, I thought everything in cars were belts and rubber...never had I heard of a chain (not a car guy by any means.) They also told me it would cost a solid $2500 to fix!!! After picking my jaw up off the floor, I decided to call GM while my car was in the shop and ask if there was anything they could do. The warranty on the vehicle had expired less than a year ago from the original owner and I was hoping they could somehow extend that or at least help me out somehow. I left the car at that dealer for about 3 days while I waited for GM to call me back. Once they did, I did not even know if I was talking to GM...I kept getting transferred between lines...and not to discredit any of their employees on how much they know, but I kept getting connected to individuals with very poor english and it was a very hard time understanding them most of the time. After the 3 days they finally called me and told me there was absolutely nothing they can do. I told them I had googled this issue and ALOTTTT of users with cadillacs 2005 and up with a 3.6liter engine were reporting timing chain issues on so many cadillac forums...and the individual's response was "we are not aware of any issues regarding this vehicle and timing chains at this time...sorry." I was blown away...how can they disregard this? I have spent the past 3 weeks looking through forums where so many owners have had this issue and have reported it to GM....I convinced a family member to lease their current vehicle from GM...now I am not so sure that was a good idea at all from the way I was treated. Being a young member of society and striving to maximize my earning potential, I am sure this will not be the last car I own...and based on this experience, it may be the last GM.

    Aside from all of this nonsense, are there any suggestions/recommendations from STS owners who have endured this issue before? Does anyone know how long the chain lasts after it has been diagnosed with the need for replacement? Any help would be greatly appreciated since Cadillac provided me with absolutely ZERO support. Thanks a lot!

    As what i do at your place:
    1. Buy timing chain kit. Just parts would cost about 500$
    2. Find a good repair shop which can make it for a reasonable price. It should be much less than 2000$. Nothing too hard and about 2 days to make.

    There are specific chains for each engine, if that's what you're asking.

    Have the dealer check the VIN for a special warranty on the timing chains. I have a 2008 and I have a 10 year 120K mile warranty on the chains.

    They were mostly out of warranty when GM issued the extended coverage for the 3.6 timing chains so those owners got screwed even though they have the same motor (2007s)....

    I'll ignore the fact that you're a Packer fan since you're a fellow Caddy owner

    Good luck with your timing chain adventure!

    Lotsa luck. Same as the Northstar head gasket issues, same as the oil leaks, same as the 3.6 oil consumption problems, same as the persnickety FWD suspension vibrations; and the list goes on and on - GM will placate and make mushy sounds but will do absolutely nothing......... That costs money and they won't give you the sweat off their butts.

    We're in a DIY car in a DIY world. If you like the marque enough you'll suck up the price of ownership; otherwise you'll switch to Lexus or Hyundai. Yes, a Cadillac can be repaired or patched up - but never expect one to be anywhere close to trouble-free or long-term reliable.

    "Cadillac" is no longer Cadillac - it's the exact same piece of throw away merchandise as a cell phone or laptop - the price is a bit higher.

    FWIW, HP laptops can be fixed and there is lots of help available on YouTube. Too bad they don't make cars.

    Re: 2006 STS timing chain issue

    Let's see, a car that is essentially 8 years old and you are expecting an extended warranty on a part that has a high failure rate? Back in the early 70's if your car lasted 8 years before having to be scrapped you were doing well. When I was starting out (in the late 70's), I think I had a Monza - not a Cadillac. Yes, I had to throw it out after a very few years but of course, it wasn't new when I got it.

    Re: 2006 STS timing chain issue

    Buddy for a car that is 8 years old, and still holds a value of nearly $11k, you are absolutely right that I will hold such expectations on warranties. Again, I just graduated college...with a ton of loans...and decided to take on yet another one because I deemed this product worthy. GM should acknowledge not just my decision to buy one of their cars, but each individual that has posted here and owns a GM vehicle. Yes sure this is an idealistic thought...and what I am saying is but a dream in a dog-eat-dog world, but I assume this is why someone had the idea to put CadillacForums.com together in the first place...to bring enthusiasts and owners together in one place so they can get the help they otherwise would not be able to get alone.
