The vehicle failed to restart. The vehicle was towed to a dealer where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 1,700.

Car shut off in the middle of the road while driving and auto braked. Had to get a tow. Dealership said engine is bad now.

The driver-side front door and related body fit/sealing system appear to be defective. The door is visibly uneven and misaligned with the surrounding body panels, resulting in excessive door gaps and significant air intrusion into the cabin while driving. The condition is available for inspection upon request, and photographs and videos documenting the issue are available. The excessive air intrusion creates substantial wind noise and driver distraction while operating the vehicle at highway speeds. The misaligned door also raises concerns regarding proper door sealing, structural fit, weather protection, and occupant safety in the event of an accident. A vehicle of this age and condition should not exhibit such defects. The condition is consistently reproducible during normal driving, particularly at highway speeds where excessive air enters the cabin through the driver-side door area. (If applicable, add: "The vehicle has been presented to an authorized Chevrolet dealer for inspection.in FH dailey chevrolet San leandro, they replaced weather strip, but air is more then what it was before, they declined my service and told me to take the vehicle where I purchased from in epic chevrolet Sacramento. No vehicle is not inspected by anyone. No warning lamps or diagnostic messages were displayed. The primary symptoms were visibly uneven door alignment, inconsistent door gap measurements, and noticeable air intrusion and wind noise while driving.

The 2026 suburban has a loud wind noise coming from the driver window and door side and the passenger side . The wind noise in abnormal and very high and it could be the weatherstripping and the door stripping and latch because the driver door needs a hard push to close completely but there is wind noise coming from the driver and passenger windows and doors . This create a safety issue that the doors if not sealed properly and the could open while driving on the highway . Also for a vehicle that has a price tag of 100,000 dollars the door seals and window seals should work up to standard and not be loose or defective and cause a very high wind noise . The safety issue is the driver door or passenger door can open while driving and cause an accident . This is a manufacturing defect that GM NEEDS TO ADDRESS urgently

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.
