Look. I know they are covered by powertrain portion of the bumper to bumper warranty. I have bought a new car, not leased every 3 yrs since I was 18. So I know how powertrain warranties work. I guess you didn't understand my statement. Alot of times car companies, when they find that a part or design has had higher than normal failure rates based on similar segments in the industry will send a letter that states the higher than expected failure rate and will say to retain the letter for safe keeping. The letter will also state that that if the failure of said part happens after the factory warranty then it would be fixed at no charge to the customer. It also states that if you've already paid for a repair for said part that you can file for a reimbursement for the repair. It is much like a voluntary recall without doing a full out recall and fixing all cars effected. It just covers the original owners incase of a failure outside of the factory warranty. My qoute wording " We know we used crappy parts in your engine to save money, but now to make it right we will honor engine repairs due to piston failure outside of our factory bumper to bumper warranty." Was to show my frustration regarding the situation. Smitty, Thanks for your understanding, as I have received a few of these exact letters over the years from Jeep, infiniti, Mercedes, and land rover. This is a way for companies to "do the right thing", and not get hit financially all at one time for a recall. It is simply like a tsb that is sent to customers, but offers repair beyond the factory warranty if there is failure. There is nothing wild and unfounded if there is a tsb for our 2.0t pistons. I am not making accusations as we are not in a court of law, we are simply in a forum where I am voicing my displeasure that a lot of engines may have received faulty parts. As a loyal Gm stockowner i have been very displeased with the way they handled the ignition recall fiasco, but I stuck with them and bought a premium ats like you except I wanted more performance, so I opted for a turbocharged engine. I did not expect to get a vehicle that had deficient engine internals. If you owned a 2.0t you would also be more understanding and probably not very excited either.
