NHTSA Complaint #11691096 — 2023 CHEVROLET SILVERADO 1500

The 2023 Chevrolet Silverado 1500 High Country has experienced multiple powertrain and transmission failures beginning shortly after purchase. The issues include violent shifting, hesitation, and stalling, particularly while accelerating or decelerating. These malfunctions create serious safety risks—especially when merging, turning left across traffic, or entering intersections. The truck has been returned to authorized GM dealerships multiple times for diagnostics and repair. GM service departments confirmed transmission faults but have not successfully resolved the issue despite repeated attempts. The same problems reoccur shortly after each repair. At times, the vehicle has entered “limp mode” unexpectedly while driving, causing a loss of power. On at least one occasion, this occurred while driving on a busy highway, forcing evasive action to avoid a collision. Warning lights such as the “check engine” light and service alerts frequently appear before or during these incidents. To date, the vehicle has been inspected by GM-certified technicians at authorized dealerships. A case has been opened with GM customer care and BBB AUTO LINE arbitration has been initiated. The truck remains unreliable and unsafe to operate, especially with children on board. The risk of sudden power loss or drivetrain malfunction poses a clear hazard to occupants and other drivers.
