Vehicle: 2025 Chevrolet Traverse on [xxx] at approximately [xxx], while driving south on [xxx] , my vehicle suddenly shut off without warning resulting in a complete electrical failure. During this event, I lost the ability to accelerate, activate hazard lights, unlock doors, open or close windows, or use the onstar system. The vehicle restarted briefly but then shut off two additional times before I could safely move it off the road. There were no warning messages or signals prior to this incident. This created a serious and immediate safety hazard, as I was unable to alert other drivers or exit the vehicle during the failure. I am requesting a formal investigation into this issue, documentation as a safety defect, and immediate corrective action. This incident poses a significant risk to driver and passenger safety. The vehicle has been towed to the dealership it was purchased from. The problem has not been confirmed or reproduced by the service center. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
El 6 DE enero DE 2026, minutos después DE retirar el vehículo del concesionario tras un servicio DE frenos, el sistema DE enfriamiento presentó pérdida total DE refrigerante debido a una manguera del radiador rota. El vehículo fue regresado inmediatamente y quedó retenido por recomendación técnica DE no conducirlo por riesgo DE sobrecalentamiento del motor. La condición representa un riesgo DE seguridad pública si ocurre durante la conducción, ya que puede provocar pérdida súbita DE potencia, detención inesperada del vehículo y posible incidente vial. El 21 DE enero DE 2026, durante inspección previa a entrega, se detectó una segunda falla: módulo onstar inoperante (gps no funcional). Ambos eventos fueron diagnosticados por el concesionario autorizado. La pérdida súbita DE refrigerante y posible sobrecalentamiento del motor implica riesgo DE falla mecánica repentina, pérdida DE potencia o detención del vehículo en circulación, lo que puede causar un incidente vial. El concesionario indicó explícitamente que no debía conducirse el vehículo bajo esas condiciones. Sí. Ambos problemas fueron confirmados por el concesionario autorizado: primero la falla del sistema DE enfriamiento, luego la falla del módulo onstar. El vehículo ha sido inspeccionado por el concesionario autorizado. El fabricante ha sido notificado formalmente y existe un caso abierto con su departamento DE atención al cliente. No existían advertencias previas. Las alertas y ventilador excesivo aparecieron minutos después DE salir del concesionario el 6 DE enero. La falla del gps se detectó el 21 DE enero durante inspección previa a entrega. El vehículo continúa retenido por reparación pendiente y no ha sido devuelto en condiciones seguras o funcionales.
Initially, the engine would intermittently fail to start and at times would not start at all. I took the vehicle to a certified Chevrolet service center, where the battery was tested and found to be functioning properly. They later concluded that a faulty front-view camera was disrupting the electrical system and ordered a replacement (my first visit was Friday, 9/26/25). I took the car home for the weekend due to family obligations. On Monday, 9/29, while driving back to the service center, the engine suddenly shut off on a local road. The brakes went completely to the floor for 3–5 seconds before the engine restarted—just before I nearly collided with another vehicle at a red light. I reported this immediately, and the dealership kept the car for further testing. On Thursday, 10/2, they informed me they found no additional issues and believed the camera was the root cause. However, the problem persisted. On Sunday, 10/5, while stopped at a red light at hawthorn st. And memorial dr. , the engine shut off again as I began to accelerate. The brakes sank to the floor, and I had no steering control for approximately 5–7 seconds before the vehicle restarted. My wife and I were extremely shaken, especially with our children in the car. On Monday, 10/6, we contacted roadside assistance to tow the vehicle back to the service center. After additional testing, we were informed that the battery had failed this time and was replaced. However, replacing the battery does not reassure us that the engine and braking system will not fail again while driving, or the brake failure would happen again when the battery is low - which poses a serious safety risk to our family. When my wife called gm to report this issue, all they offered was 200 points worth of rewards. . . . We originally bought this car for safety, but not this has been compromised and we no longer feel safe. Thank you for your attention to this matter. I am happy to provide any additional information if needed.

The contact owns a 2025 Chevrolet Traverse. The contact stated that immediately after purchasing the vehicle, the vehicle experienced several electrical failures, including the on-star module malfunctioning. The on-star module was replaced twice. During the failures, the cruise control feature became inoperable, and the computer updates were not received. Additionally, the battery became drained several times, and the vehicle needed to be jump-started. The contact also indicated the shark fin antenna had ejected from the vehicle while driving. The vehicle also abruptly stopped while driving on several occasions, and while driving, there was an abnormal metallic scraping sound coming from the engine compartment.
