    You know--the more I think about this the more pissed off I get. These cars have both a low oil pressure warning and a low oil level warning. Whether they work or not is not your problem. If indeed your crankcase level was low, you should have had a warning (why are those systems there and explained in the owners manual). Also, if indeed the engine starved for oil, many other systems would have failed long before the chain failed. I personally think you need to go on the offensive and put your dealer on the defensive. I'm sure they will give you the normal crap about checking oil level, but ask them why the vehicle has indicator lights and why as a customer you shouldn't count on them. Also, what was your oil life indicator when this happened. If it still shows a fair amount of oil life remaining, you can challenge them on excessive consumption even though you had lots of oil life left. I know that this stuff is difficult for a lot of folks, but there's a lot of money involved here. Again, as an engineer, i don't think that a timing chain failure is the first failure to ocurr due to low oil pressure. Ask them about the 2007 failures that were attributed to vendor quality and how do they know your's may be different.

    Some 2005 and 2006 3.6s have had timing chain problems. Local dealer told me that if you have a warranty, you are ok. If not warranty, big trouble. (You are on your own.) Repair is a real headache too.

    This is the first I've heard of a timing chain issue. Good to know.

    Re: Timing belt broke on 2006 sts with 53,000 miles!

    on the 2005 v8s when does the chain need to be serviced normally?

    How about the v6s?

    I don't think there is any service to be done on chains--they should normally last for life--whatever that may be.

    It was a vastly different car, but when some Quickie Lube grease monkeys started my 1980 Mustang with no oil in it (in order to flush the radiator), it only took 2-3 minutes till the timing belt snapped.

    There is no service interval for timing chains. The tensioners and variable cam timing actuators are hydraulicly operated so it just needs the proper level of oil at all times and also is part of the reason synthetic oil is specified for these engines.

    The oil life monitor does not monitor oil level, you can be low in oil and the reading will not change because of that.

    Don't know about this generation of STS but my 2000 used oil about a quart between changes. When it got down below 1 qt a warning came on. So I had 7 qts left and just needed to add a quart. My 05 V8 uses no oil, not sure this is good or bad. But I would expect there is a warning in the DIC when oil levels drop.

    The reason I asked about oil life remaining was to get an idea how long it had been since his last oil change and the potential oil that may have been used since his last change.

    What's the real story? Did it really just up and die at 53k? If that's true, a good dealer would back you with GM. The end of the warranty period isn't a cartoon car explosion.

    This IS THE REAL STORY. No reason to lie just left the dealership. The service manager just told me he knows nothing of timing chain problems with 05 ans 06 but the 08 and 09 cars have had timing chain problems. I will be contacting cadillac,they are about to lose a long time customer This is at the morries cadillac in golden valley mn.
