The timing chains and guides used on this model, as well as some earlier models are drastically undercapable, and subject to stretching at premature times. This can cause a catastrophic engine failure. While some earlier models have been subject to recall, gm has not stepped up to the plate and fixed the issue by redesign. The issue persists, and needs to be addressed. At present, my vehicle is showing the p0008 code, repeatedly, which indicates this issue. While I have been lucky to this point, in that I have not had a catastrophic engine failure, I believe that the problem is imminent. This is a well documented issue amongst the owner community, and gm has ignored addressing it.
Steering: seems vague when in motion at highway speed. Other: rear tailgate opens while driving, sitting still w/o the key in the ignition. Contacted gm and customer service told me it was my problem not theirs. Engine: sounds like a meatgrinder on cold start up, if the engine fails will loose steering, brakes and possibly control of the vehicle.
