NHTSA Complaint #11646485 — 2022 GMC YUKON XL

I was 450 miles away from home. Travelling at 80 mph in the left lane of Interstate 35 when the Yukon stopped accelerating and started coasting. I looked at the gauge clusters on the dash and it said Press Start to Shift. I looked at the shifter and it had automatically moved from Drive to Neutral. It would not move back to Drive. I then pressed the Start button like it said on the dash and the whole vehicle shutoff while still at highway speed going 70mph and still coasting. I put hazards on and moved to the right sliding in-between two 18 wheelers who gave me space thankfully then I was able to get it to the shoulder. Once stopped I moved it into Park and pressed the Start button and the dash said "unsafe conditions unable to shift", or something like that. After 2 minutes of pressing the Start button, I was able to get it started again and we started back on the road. After 2 miles, I was once again back to 80 mph in the left lane when it happened again. This time I was barely able to move off the road. We were on a long turn to the left and several 18 wheelers were all around. Once stopped, it never started again. The engine shutting off at highway speed with 18 wheelers all around put myself and 2 family members at serious risk for injury and we were just leaving a family funeral. And the 2nd time it happened, I was not able to fully pull over either causing 18 wheelers to come very close to hitting us as we were stuck on a left hand turn with a 60 mph left to right cross wind making it very dangerous for us while we waited 80 minutes for a tow truck. The only indication of a problem was the engine light on after we were stopped nothing before hand. no sound, no warning, no vibration, just an immediate shutdown. The dealership it was towed too said it is a complete engine failure and the bearings more than likely failed and I will have to wait for a new engine. Most likely the same faulty 6.2 engine. Please do something before someone dies.
