What Owners Say
"I take excellent car of all my vehicles and this formerly awesome vehicle started pinging from the engine compartment and within one day completely failed. GMC dealer tried to fix but say I had a bend rod and may have a camshaft issue tool Intake and exhaust valve lifters messed up. This is mostly highway miles with mostly easy driving. I have all records. Maintained by dealer. Flaws in this vehicle are major and I am so upset because I do not have reliable transportation and now I have to trade in with hardly any resale value..."
