On January 29, 2025, while my wife was driving our 2022 Chevrolet Suburban with a 6.2L gas engine on a state highway, the vehicle suddenly lost acceleration and power to the wheels while accelerating to the posted 55 mph speed limit. This occurred without any prior warning, creating a highly unsafe situation in morning commute traffic. The vehicle was immediately taken to a Chevrolet dealership, where the issue was diagnosed as a failed transmission control valve. This failure, which resulted in a complete loss of power while driving at highway speeds, is a known defect affecting certain GM models. The part in question, the Transmission Control Valve, is currently in high demand and is on a national backorder due to numerous similar failures. A recall has already been issued for diesel engine models with the same problem, but no recall exists for the gasoline-powered versions like ours. Chevrolet has confirmed the diagnosis and is aware of the issue, but the replacement part is currently on a national backorder, and the repair has been delayed indefinitely. Since the incident, the vehicle has been undriveable, causing significant inconvenience, and Chevrolet has been unable to provide an estimated date for repair. The sudden loss of power created a dangerous situation on a busy highway, as there were no warning lights, messages, or symptoms prior to the failure. This is particularly concerning given that the part involved is on backorder due to the widespread nature of the issue. Chevrolet’s lack of a clear repair timeline, coupled with the fact that this issue has been identified in other models, raises questions about the company’s response and whether a broader recall or safety bulletin will be issued for vehicles like ours. The vehicle’s failure has not only been a major inconvenience but also a safety concern, highlighting the need for urgent attention to address this defect.
