On Sunday, when my brother came down from RI with his new 2012 Cruze LT RS that I was dying to drive to compare to my crappy shifting 2011 Cruze LTZ RS, he mentioned that he had to bring in his wife's 2011 Buick Regal because of a timing chain problem. Evidently, when the Regal is first started in the morning, it makes a racket. I believe he said that the timing chain has to be replaced. She only have a few thousand miles on her car. Evidently, the Regal isn't the only car affected?I have a 2011 with 22k miles. At 16k the timing chain gasket went- three weeks to fix. At 22k the crankshaft seal went on the freeway at 70+ mph. This caused the serpentine belt to come off- no oil, no water moving. Still 70 MPH in traffic. Got off the road to a motor that had an unusual sound- imagine that. Still waiting to hear how Chevy/dealer will handle this one.
