My 2022 Chevrolet Tahoe diesel unexpectedly lost power while driving. I was stopped, made a right turn, and accelerated to approximately 34â40 mph on a two-way street when the vehicle suddenly shook, shifted into neutral, and the engine shut off without warning. There were no warning lights, dashboard messages, or prior symptoms before the failure. I was driving with two young children secured in car seats at the time. This created a serious safety risk because the vehicle became disabled in the roadway, and I had limited control while traffic was present. The vehicle has not yet been diagnosed, and the exact failed component/system is unknown. The vehicle is available for inspection upon request. The incident has been reported to a dealer or service center, but the problem has not yet been confirmed or reproduced at this time.
