Most recent owner complaints, unedited.
While driving on a city street the 2014 gmc sierra 6.2 l v8 lost power and started running rough as approaching an intersection. I was able to stop, and reverse the vehicle away from the intersection, to get out of traffic. The engine light was flashing and the truck shut down, it was unable to restart. The truck had under 60,000 miles on it at the time of the first incident. It was towed to a gm dealer shop for repair. This first incident took place in august of 2019. The rocker arm and exhaust spring had to be replaced in the #2 cylinder, the cylinder head had to be rebuilt with a new head. In addition they replaced 4 fuel injectors. In december of 2019, a second incident happen while driving on a city street, the engine started running rough, I was close enough to my house to get it home, park it and it was towed to a a certified gm dealer shop for repair. This time it had 61,752 miles on the vehicle, the number 5 spring broke. It is at the shop waiting on spring replacement, they are in backorder, there is not projected time the repair will be complete.
Brake failure. The brake vacuum pump failed. I marked the failure as today as the dealership confirmed the failure. The failure occurred a month or so ago. It does not happen all of time.
