NHTSA Complaint #11669009 — 2022 CHEVROLET SILVERADO 1500

I was driving my truck with my two young children in the back seat. I was accelerating to merge onto the interstate, and at 8th gear (around 74 MPH) I felt and heard a BANG and lost all propulsion, as if the transmission went into neutral. I revved several times and had no power to the wheels. I had to quickly check traffic behind me and find a place to stop on the side of a busy interstate, with two young children in the truck. While decelerating, I had no engine power and the transmission shifted from D to N to P while I was still moving - although it felt like it was still in N. As the truck decelerated, the engine shut off while in motion (around 30-40mph) and I came to a stop. As I was coming to a stop, I noticed I had a solid CEL/MIL along with several other warnings. I was unable to crank the truck - crank but no start - and unable to shift from P. Had I not been able to find a safe place to stop (e.g., in heavy traffic on the interstate or in city traffic) I surely would have been involved in an accident. When trying to tow the truck to the dealer, I had no way to get the truck out of P to load onto the tow truck flat bed. Subsequent attempts (at the Chevy dealer) to remove the truck from the tow truck flat bed were unsuccessful, as the truck would not shift from P nor crank. This was a severe safety issue which I am not sure is powertrain, electrical, or emission related but it could have ended in a severe crash on the interstate with my children. There were no indications of any sort of malfunction or issue except for when I immediately heard and felt the bang and lost propulsion on the interstate. I drove the truck earlier in the week without issue and there were no MIL's immediately prior to the incident. The truck is at Jimmy Gray Chevrolet, Southaven, MS awaiting evaluation and diagnosis.
