Has anyone had problems with pistons in a 2011 v6? Mine is at the dealer and I was told by a GM engineer that it has piston slap.Has what sounds to me a valve train rattle at 1700 to 3000 rpms. The car has 24,500 miles on it and has had the oil changed every 3,000 miles. This car has never been driven hard and never has even seen rain!! ( sunny days only) Sits in a carpeted garage next to my 71 Chevelle most of the time. I hate to have this engine torn apart! This problem has my quite frustrated because the way I keep my cars and the fact that it is 9 Months OUT of warranty. I've heard of connecting rod bearings going bad in these engines but not pistons. I'm asking Chevrolet to step up and back their product, as they have for me in the past.
