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.

I was driving on a Chicago expressway with my family when the tire pressure light came on, within 3 mins and before we could safely pull over the tire shredded and eventually the entire middle part of the tire came off and we were thankful there was a lot of traffic so we had to slow our speed because the inner part of the tire came off and it rolled to the side of the expressway. This could have been catastrophic if another car on the expressway tried to avoid or hit the rubber part of the tire while they were driving. We had to backup an on ramp because there was no safer alternative. We were able to put on the spare and find a tire shop that was affordable to replace the tire.

To the Vehicle Safety Complaint Division: I am filing a safety complaint regarding brake service performed on a 2025 Buick Envista (VIN: [XXX]) by Suburban Buick GMC of Troy, 1850 W Maple Rd, Troy, MI 48084, an authorized GM dealership. Safety Issue: The vehicle was brought in on XXX with brake pulsation at 20,689 miles. Suburban performed rotor resurfacing on all four rotors and certified the repair as complete and verified on XXX. On XXX — 13 days after Suburban certified the repair — Moran Buick GMC of Sterling Heights found the rear rotors causing the identical brake pulsation symptom. [XXX]'s service advisor determined the rear rotor was rubbing against another component and stated in his professional opinion that Suburban's prior service caused the condition. The corrective repair was processed as a GM warranty claim. Safety Concern: A certified brake repair on a 21,342-mile vehicle failed within days of service. The failure involved the braking system — a safety-critical component. The original service manager dismissed the customer's safety concern by stating failure would depend on "how you drive." Dealer: Suburban Buick GMC of Troy, Registration Number XXX, operated by Lithia Motors, Inc. (NYSE: LAD) Supporting Documentation: Two authorized GM dealer repair orders documenting the failed repair and corrective service are available upon request. I respectfully request confirmation of receipt of this complaint and assignment of a case or reference number. I am available to provide any additional documentation or information required to support this complaint. The complete documentary record, including both repair orders, the independent inspection findings, and the complete correspondence record with Lithia Motors corporate, is attached. Sincerely, [XXX] Authorized Representative for [XXX] [XXX] [XXX] Attachments: — [XXX] v.
