NHTSA Complaint #11655486 — 2022 GMC SIERRA 1500

Engine had already had a full replacement within the first 35,000 miles. Driving down the road at 55 MPH and engine stops completely. Have to coast into a neighborhood. Luckily I was able to get out of the road. Pulled over and turn the truck off. Tried to start it and it never would turn over. Came back an hour later to see if it just needed turn off for a bit and restarted. Tried to start it and it started right up. Drove it around the block and then decided to drive to an auto store to test the battery. Before I could get to the store the truck shut off again while driving in the middle of the busiest road in town during rush hour traffic. Had it towed to the dealership and they said I need an engine replacement. This 6.2 motor is completely unreliable and a hazard to anyone driving it. No warning lights, no indication it was going to fail. I keep up with all my maintenance. I drive under control and at the speed limit and I don't tow anything.
