2026 Chevrolet SuburbanRecalls, problems, MPG & safety

“While exiting the highway my vehicle suddenly lost power and could not move. I could not put the vehicle in neutral. The engine had completely seized. As a result, my car got hit by a Semi-truck.”

“Second row door lock/unlock buttons do not function properly. The vehicle may be locked from this position but is unable to be unlocked. This allowed a small child in a car seat to lock themselves in the car but unable to unlock the vehicle using the corresponding button on the door. This is a serious issue which left the child trapped and required rescue from the fire department. This is a known issue for all GM/Chevy SUV from model year 25&26”

“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.”
