Without warning my 2016 Yukon Denali jerked so forcefully into drive it felt like we were hit from behind. It went into gear and sped into intersection and stalled. We were almost hit. This is a huge problem with2016 GMC's and they are aware of it. It is the 8 speed transmissions that are causing this. They refuse to help get it fixed. I think they should be forced to! I will be out thousands if I can even find a shop that can get that transmission., They are back ordered because so many failures.

Bought SUV 6/25/2016 the same weekend the engine turns off after a left or right turn :it has happened 3 times so far. 4 week old 2016 yukon denali xl, has stalled 3 times in last 4 weeks, engine cuts off after a left or a right turn only after a short drive out of home. The SUV has to be restarted! Could have easily had an accident or worse. I took it to the westpoint gmc dealer, 3 times. 1st two times, all of service deptartment could not diagnose the problem. Today, after a stall, I called onstar, who ran a diagnostics test,but onstar found nothing of value , I left it at dealership and contacted district mgr. Matt tillson . I was told that they would escalate the issue. I did tell dealer that gmc and dealership would be at fault if vehicle is involved in an accident and stalls nor stops while I am driving. I did not want the vehicle back without the problem having been fixed. Its day 6 today. I need to make it absolutely clear, I will not take the vehicle back untill the problem has been diagnosed, and fixed. I do not want me or my family or gm service employee injured, or worse, or to be involved with a possible accident in my gmc yukon denali xl. A field service engineer should have been on this case already ! Will it take an accident, or injury before someone gets assigned?
