The contact owns a 2016 GMC Yukon. The contact stated that the vehicle was initially repaired under warranty for a bent push rod in cylinder #4; however, the failure recurred. The vehicle was repaired another time at the expense of the contact's son, who previously owned the vehicle; however, the failure persisted. The contact stated that while idling and while driving, the engine was misfiring and running rough. Additionally, there was a significant amount of smoke coming from the exhaust pipe. The check engine warning light was illuminated. The vehicle was taken back to the dealer, where it was diagnosed, and the dealer determined that the engine needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was contacted and informed that the repair would not be covered because the vehicle was out of warranty. The failure mileage was approximately 27,000.

Misfire then replaced plugs,coils and wires, then change fuel injector, and problem still there, then started truck and was tossing power and motor started ticking. Every shop told me this is the same common problem they're having with all 6.2L engine and they're all on recall by GM. I know 2016 are not in recall but I think they should be because this problem is in all 6.2L engine
