| Power Train problems |
On February 28, 2026 at approximately 6:08 pm, while traveling at approximately 40 mph on s. Third street extension near route 119 in mebane, nc, my 2026 Chevrolet Suburban high country experienced a sudden catastrophic drivetrain failure at 2,010 miles with no prior warning symptoms. A loud bang was heard, and the vehicle decelerated sharply. Dashboard warnings appeared for transmission and steering service. The vehicle continued approximately 60 feet while producing severe grinding noises before all four wheels locked completely and the engine stalled. The vehicle was rendered completely inoperable and stranded in the roadway. My wife was a passenger. Onstar was contacted and dispatched local law enforcement to provide traffic control while the vehicle was disabled. Onstar also arranged emergency towing to modern Chevrolet in burlington, nc. This failure is consistent with the transmission control valve body defect covered under NHTSA recalls 24v797 and 26v085 affecting gm 10-speed automatic transmissions (10l80). Gm has been aware of this defect since at least 2024 yet vehicles continue to experience catastrophic wheel lockup.
