NHTSA Complaint #11646527 — 2022 GMC YUKON XL

While driving on the highway the engine just shut off with no warning or other indication of problem. The dashboard computer instructed to restart the vehicle, which it would not restart. Managed to get to the side of the road. But the vehicle was unresponsive. After about an hour the lights in the rear of the vehicle flickered, so I attempted to re-start -which it did, and was able to drive the vehicle to the dealer (about 20 miles away). Where the car remains today. The incident occurred Feb 2. Took the dealer until 2/6 to advise me that the engine would need to be replaced. At that time they indicated they would need to car for about 2 weeks. I contacted them on 3/3 and they informed me they had no idea when they might be able to get the parts to replace the engine - there was a 3,000 engine backlog? Clearly there is a major issues with these engines; how are they allowed to continue to sell these vehicles, and allow current owners to operate them without a notice? While I was fortunately able to get to the side of the road - have in the car lose power suddenly lose power is clearly a safety issue!
