NHTSA Complaint #11679338 — 2021 CHEVROLET SUBURBAN

Was driving about 45 mph on 2 lane road. All of a sudden, without warning we lost power (had no propulsion). Luckily there was a residential side street that we were able to turn onto and get off of the highway with no shoulder. We coasted to the side of the street and called a tow truck. Had we not been able to get off the road, we would have been dead in the road, blocking an entire lane of a busy 2 lane highway without a shoulder to pull off on. There was no warning prior to incident but a message did appear during the incident. I believe it said "Loss of propulsion." We turned off the vehicle, then tried to restart it. Engine attempted to restart, but it made a horrible noise & wouldn't restart. Still had battery power. Vehicle was towed to a local dealership where it is currently being evaluated. We know of a massive recall on the 6.2 l engines. Ours is a 5.3 l engine. So far I'm seeing many people having problems but no official recall for the 5.3 l engines that are having THE SAME issue as the massively recalled 6.2 engines. This needs to be looked at. Our Vehicle only had less than 30k miles on it. We bought it new and have done routine maintenance.
