    I got a recall notice. It is to reprogram the computer to tell you when you need an oil change. It states that "under certain conditions the timing chanin could wear prematurely". So they are changing the oil change info. Not the timing chains.

    Re: 2008 CTS Timing chain recall?

    I have never been condition on 3,000 miles oil change and never followed this “rule”. If you check most of the European car makers recommend 10,000 – 15,000 kms (roughly 6,000 – 9,000 miles). Nissan and Infiniti recommend 3,750 for severe conditions and 7,400 miles for normal driving. And this is with mineral oil! In my 30 years cars ownership, having own many cars from different manufacturers I have never had any problems with timing chains! The CTS is the first one. And this is despite almost of over-maintenance!

    As I said before I do not have problem with recalibrating the chain “stretch” parameter however I do have with the OLM recalibration. And to name it “Customer Satisfaction Program” is just plain stupid and a snap in consumer face. I would like to meet with this idiot who came with this term…..Then maybe better not, what would I learn?

    As for me – I am going to switch from Mobil1 to Pennzoil Ultra and change oil every 4,000 miles. Just to be on safe side.

    The question I would ask now who is going to pay for the extra oil changes after OLM recalibration? I doubt GM will. Even though this is their fault. Looks like possible class action….

    It is funny how they worded it "under certain conditions" - what are the conditions?

    Not sure who can do oil change for $55. Yesterday I bought 6qt od PU (Pennzoil Ultra) and it cost me $52. Add the filter and it is $65 or so. And it is without labour!

    Anyway, I have never ever owned a car that required changing oil every 3,000 miles. And never had any problems.

    Re: 2008 CTS Timing chain recall?

    I just received my "Customer Satisfaction Program" letter for my '08 3.6DI AWD also. I definitely think the oil life monitor is currently too conservative so I do not have a problem with them changing the calculations to reduce the change interval. I went from 33K to 39K miles and the oil life monitor is still reading 52%. So if conditions stay the same that puts it at about 12K - 13K miles before an oil change. Even with synthetic oil I think this is too long.

    Re: 2008 CTS Timing chain recall?

    Just dropped off my car for service regarding the battery dying only 2 weeks after it was replaced under warranty. Even though I haven't received a letter, when the tech plugged in my VIN he told me there was an open warranty issue for the timing chain. I told him I was aware of that and that they would also reprogram the oil life monitoring system. He said - "you really have researched your vehicle!" - Thanks to you Cadillac Forums!!!!

    Re: 2008 CTS Timing chain recall?

    Hello All,
    I own a 2007 CTS V6. I received a letter over the weekend explaining that the timing chain could wear prematurely and cause the illumination of the Service Engine Soon light. Also, the timing chain wear can be affected by the age of the engine oil and driving conditions. Furthermore, "what they will do" is; change the calibration of the engine control module, including the engine oile life monitor (incorrect as I so hardly learned), which in most cases will reommend more frequent oil changes.

    My issues....I took my car in for services as it was lagging in June 2009. I was told by the service manager that my timing change was "stretched," and will eventually break. However, they cannot replace it until it breaks....I explained to him that I drive alot of miles and all highway (high speeds), what will happens when this breaks. He explained to me what "could" happen and ever since I've been waiting for this to break - fortunately - it hasn't. Now I receive the letter stating the issues that could happened - I'm already aware and I've already been told my timing chain is "stretched." I spoke w/a representative via phone and said I'm already experience what you stated "what" may come in the future. She told me to contact my dealership and see when they can order the part. I contacted the dealer and they've told me they cannot replace the timing chain w/out the "check engine light" being on..... This doesn't seem right to me??

    How would they have known that the chain was stretched without the check engine light coming on? I don't know a way of measuring the chain's stretch without getting into the engine.

    Re: 2008 CTS Timing chain recall?

    My 2011 CTS Coupe 3.6L DI hit 5,125 miles at 2% oil life remaining and had the dealer change the oil. I spoke to a pretty knowledgeable technician that tells me the goal with the new software is to end up with about 6,000 miles at 0%. He was not sure why mine was a little sooner. Timing chain replacement keeps them rather busy, but he tells me that the engine is a non-interference engine, so a broken chain wouldn't cause a piston to hit a valve. He has not yet seen a broken chain.

    If I owned a car covered under the recall, I'd be tempted to do nothing while under warranty - if I get a CEL under the old program it would result in a new timing chain as opposed to a a stretched chain and no light with the new software. I'd have the recall done prior to the notification period or warranty expiring. And also start changing the oil at around 50% (my '08 CTS would go to almost 13K miles if I let it).

    For anyone with a 2011 under the no-cost maintenance, my dealer tells me to bring it in for oil changes at 30% or lower as that is the level where GM will reimburse them.

    this is a very interesting information. My chains were replaced at approximately 42,000 miles. Now I have close to 46,000 and am planning on oil change this week. I want to make sure the oil is not a factor.

    As to why your OLM is showing 2% after 5,125 - remember mileage is not the only factor. The other are number of starts, temperature etc. Anyway, it confirms oil need to be changed at 5,000 miles or so intervals.

    Re: 2008 CTS Timing chain recall?

    the 3.6L engines ARE interference engines ... however that doesn't guarantee valve damage when a chain breaks

    we have seen about 25% of the cars w/ broken chains not need any valve work

    also, Mileage is not a factor at all in the OLM system - engine temp and RPM are the only variables (besides the type of engine since other variables in the algorithm are determined by the engine type)

    if your 2011 was at 5,125 TOTAL miles and at 2% oil life remaining that would make sense since usually the first oil change is supposed to be done on a quicker schedule (but I thought that first oil change was dictated by mileage as per the owners manual)

    Re: 2008 CTS Timing chain recall?

    When I took my car into the dealership in June of 09, I was having issues with it lagging, missing. When I took it in they drained the oil, etc. Then told me that the missing is due to the timing chain being "stretched." Regarding my earlier issue, the dealership said they would perform the recall but not the timing chain until the check engine light came on (which mine hasn't).

I simply do not have time or desire to put up with all this bs...
    BMW is treating their customers the same way right now. I have 2 friends with fuel pump failures in x35i applications. In fact, one of their BMW's has been sitting for over a year waiting on warranty claims. This kind of treatment isnt a GM problem, its a big business pushing around the little guy problem. Look at Toyota and the 'soft' recall of the rusting frames in their pickups. I know someone who had his Tundra bought back by Toyota for MORE then market value, after 6 months of fighting to get a claim...yes, MORE. But yes, like other 'good' brands, GM continues to be unimpressive.
