I'm just guessing, but I'm thinking the timing chain failures (which are as big or nearly as big an issue on here, or at least were about 2 years ago) are caused by lack of engine oil. Sounds like, after your engine has lost, burnt, consumed a significant amount of oil, that the timing chain went cause it might just be the"weakest link". Wish I could say lol, but it's definately NOT funny! Also, from what I've gathered here, I don't believe there is a warning for low oil...jeeez, my 2000 GMC pickup has that!!! The more I talk to other Cadillac owners, the more I hear that there are many oil users...not just the 3.6 litre VVT motor. I have a GMC Vortec 4.8 motor with 201,000 miles that will not use a drop of oil in 5000 miles, but Cadd says a quart in 2000 is okay, even though they set the computer for a 10,000 mile oil change. DO THE MATH!!! That's 1 quart left at your oil change interval!!!

No, unfortunately I'm still waiting on the dealership where we purchased it to do the "tear down" and provide a report to the warranty adjuster. This is the first time in all my years of purchasing new or used cars / trucks that a major mechanical failure has occurred. I have never had to deal with warranty companies and so far am not too pleased with any of the treatment we have received - we have been treated as though we blew up this motor intentionally!! I will email further information if we do not receive a satisfactory resolution within the next 48 hours. Thank you!

The oil was full when it was checked by the dealership when it was towed in - and I say full - it was 1/2 quart low which we and they believe was due to the oil that was lost when the engine blew. It has always been serviced at this dealership but I'm really starting to get frustrated with them because it has been there over a week and has not been touched!!! I am thinking of contacting my attorney to see if they can get the process moving. I have NEVER owned anything other than Ford vehicles and bought this darn car on a whim and now look - I'm stuck with pmt's for 4 more years on something that is a piece of S**T! Oh and btw, my 2007 Ford Supercrew has 210,000 miles on it and still purrs like a kitten

Sounds like a plan, csmd55! All the best.

You say "I am thinking of contacting an attorney" and GM says "sounds like a plan." Really? Good luck csmd55. I will say this: I was stuck for 10K on the loan balance when my STS blew up. The dealership ate 5K of that and helped me into a new Malibu. The dealership was GREAT (Ron Craft - Baytown, TX) but GM is still not owning up to the core issue here.

Good morning zebandco,
csmd55 stated that they would contact us further via email if they were still having difficulty after several days. I did re-read the post I responded to just to be sure and saw no mention of an attorney.
I'm sorry to hear about your STS - how is everything going in your new Malibu?

Well you know how these forums go...jk Seriously though, we still have not found out the root cause although at this point I do know that it is not the timing chain unless it just jumped time as all timing chains were in tact according to the brief update yesterday but at this point we are almost two weeks into the engine failure and my fear is that I am going to be stuck on this loan with no car as I have only had it 13 months!!! I still have 47 more payments to go! Glad your dealership worked with you to lessen the burden - I have not as of yet, pursued this option as I still do not know if the warranty is going to cover the repair(s). For me is it a GM manufacturing issue with these motors - there are way too many issues of the same kind on these engine's and sounds like they need thier engineers to go back and do a root cause analysis and figure out WTH this issue is happening repeatedly!

. . . sounds like they need thier engineers to go back and do a root cause analysis . . .
You are, of course, correct. They may have already done it, but we'll never hear the results because there are "significant" potential costs to GM involved.
The thing that I find interesting is that this has gone on for a number of years without a revision to the engine, or at least a publicized one. They may have figured out what's wrong, but don't want to talk about it. Or, worse yet, they don't have a clue -- let's hear it for Government Motors.
The only way those of us here on the outside have a prayer of determining if it's been fixed is to continue to monitor whether newer versious of the engine continue to display the problem. It's called data, and it's very hard to gather in an environment in which the prime (that'd be GM) is trying their best to pretend that there was never a problem in the first place.

Post 628 mentioned the attorney. The next post, 629, was the "sounds like a plan" reply. I may have gotten lost in the thread. My bad if so. If I have misrepresented anything please point that out as I that is not my intention. As for the Malibu, it's fine. It's not the car the STS was and I'm upside down in it, but it is not consuming oil. Seems to be holding up okay at 33K miles. While I am clearly pissed about my experience with the STS I want everyone to know that Ron Craft in Baytown TX is class act. I didn't have to go back to GM, but chose to based on the customer service experience I got with the STS which I purchased there. Up to the point the motor grenaded just out of warranty that is. The didn't have to help me at all, but they took as high a road as they could, I think.
