Sierra 2500

The engine failed. The 2022 GMC Denali had 12,000 miles on it. This was a brand new truck. We were driving home at night the engine began to make noise and then cut off in the middle of the road. We had to get the car towed. The truck was left on the side of the road on a very busy highway. The dealer confirmed the engine failed and found metal shavings in the engine. The dealer has recommended a new engine from the GMC Manufacturer. The manufacturer has not yet responded to the dealerships request. The engine light did come on prior to the engine shutting off.
