Ok, so this problem started with the oil consumption in 2013, still under warranty. Went thru all parts of the "bulletin" still having problems 3 years later. Every so many months we have gone back for other parts of this bulletin to be fixed. Fast forward 3 years the pistons are slapping. Rohirch chevy in Pittsburgh has had our car for 14 days! Nobody had called with updates at all! I have called gm 5 times I called the dealer 12 times thru these 14 days and finally today they tell me its gonna cost 5,600 to fix? We started all this under warranty! This is part of the same bulletin!!! Gm is the WORST! The right hand has no idea what the left is doing AND all they do is transfer from one place to another without any answers or fixes. Chevy sucks and so does GM!

GM says it has now been documented and wait to see if the noise level increases.

"Not a problem, it only makes knocking sounds when cold, as soon as it warms; no noise"...kinda like my roof only leaks when it rains...otherwise it is a great roof!

I know similar problems have affected the sale or trade-in price by reducing the value $4000-6000. I am pretty choked at GM over this; and realize there are many others in the same position.
