Vehicle has stalled when moving slowly and making a turn or slight turn. In all cases, the engine shuts off, all displays (instrument cluster and infotainment display) go black, and power accessories such as windows, radio, ac are all off. No warnings or service lights have appeared in the instrument cluster. July 4, 2026, morning – Vehicle stalled entering an alley, moving slowly and turning. This occurrence did not involve stopping previously to the stall as the next two did. In this instance the engine started again on its own and power came back on, though ac settings were changed. July 4, 2026, afternoon – Vehicle stalled after stopping for cross traffic in a roundabout and then moving to enter the roundabout. It was necessary to completely stop the vehicle in traffic order to restart it (depressing brake pedal and pushing the start button). August 8, 2026, morning - Vehicle stalled after stopping at a stop light and then moving to enter the intersection and turning. It was necessary to completely stop the vehicle in traffic order to restart it (depressing brake pedal and pushing the start button). We have taken the vehicle to two different GM Service Centers to diagnose and resolve the issue. In both cases the service centers were unable to determine the cause, being unable to duplicate the situation. I enclose the service reports for both - Hallady Motors, Cheyenne, Wy 7/10/20236, and Tyrrell Chevrolet, Cheynne, WY 8/17/2026.

The data screen for navigation has gone blank several times. A few times previously but 3 times in the past 2 days. The speedometer is viable but not the radio or navigation. Adaptive cruise control has occasionally alerted that it is not available & shuts off on its own. An alert yesterday stated power steering needs to be serviced but nothing is wrong. The car has turned off as I started to pull out into traffic & turned back on its self 3 times today. One time in the morning on my way to the gym at a stop light when it turned green when I went to proceed the car turned off and turn back on its self, leaving the gym pulling out of the parking lot pulling out into traffic it turned off & back on by itself & this evening after stoping at a store I stopped at the exit & when I went to pull out in traffic the car turned off & back on again by itself. Also the delay wipers do not come on themselves.
