2026 Yukon elevation with 3,957miles. I was driving down the road and pulled into the turn lane at an intersection. Vehicle cut off with the auto start/stop function and would not start back up. I continued and tried to restart the vehicle but would not start; I was blocking the lane with cars continuously going around me. Vehicle stated service transmission on the display- I was unable to put it into neutral to push it out of traffic; you are only allowed to put it into neutral when crank and couldnt get the accessory mode to come on without the vehicle trying to start. I called the local police department and they sent an officer to direct traffic until a tow truck showed up. Both observed the vehicle not starting. There were no symptoms prior to the vehicle cutting off, only once auto start/stop initiated did the vehicle not restart. Vehicle will be sent back to the dealership tomorrow to resolve this issue. I have dash cam footage of the incident and photos of the display on the screen.
Vehicle has 2200 miles, equipped with the diesel engine and failed at a red light. Gm has to install a new engine.
