I received my official letter from GM today and they extended my warranty on my engine for 3 years 100,000 miles.Did some major complaining about a noise I have which they considor normal piston slap but I know better.This noise I have comes on about 3 min after starting and goes away after about 6 min.If it were piston slap it would be at its worse on initial start up and diminish as it warmed up.Argued with the rep and service manger.With the teflon skirts and the fact that it doesn't make a noise until 3 min into warm up it cant be piston slap.The problem I have with this is that it is not transferable.Has anybody got the extended warranty and were theirs transferable?
