Within two weeks of buying, the vehicle was backfiring on engine start up. Electronic control module had to be replaced. At same time, engine was producing blue smoke on start up...entire engine had to be replaced. Since then, load balancers went out of whack and had to be fixed, ECM had to be replaced again, Heat and cooling module had to be replaced, signal light indicator in display panel has failed, rear hatch lock assembly had to be repaired, and now I'm dealing with engine ticking and loss of power that service bulletin is attributing to a lifter problem. Seems like this latter problem should be a GMC recall vice just service bulletin notice.
Recall the vehicles and get these more than isolated problems corrected at gm expense. Might prevent folks like me from thinking "let's go foreign made again. Have demonstrated to be more reliable."
