Engine seized while driving on the highway. This is the same engine that is being recalled and GM has said that the vin is not covered. The vehicle stopped running on a major highway with my [XXX] old son in the car. The dealership is saying this is the exact issue that is part of the larger investigation for GM v8 engines. There were no warning lights at all prior to the engine seizing. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2021 GMC Yukon XL. The contact stated that while driving 55 MPH, several unknown warning lights illuminated, and the check engine warning light started blinking. The contact pulled over and became aware that the vehicle was shaking. The vehicle was turned off and restarted; however, the failure persisted, with smoke coming from the vehicle. The vehicle was repaired under NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING); but the repair failed to fix the vehicle. The vehicle was taken to the dealer, where it was diagnosed, and it was determined that the camshaft needed to be replaced and that cylinder #8 was damaged and had detached. The manufacturer was notified of the failure. The failure mileage was 116,204.

This is from dealership “found customers concern of engine light is on and ticking noise found cylinder 4 lifters to be collapsed causing the exhaust gasses to be trapped in the cylinder causing the cylinder wall to dry out and leaving scratches on the cylinder wall recommend replacing motor due to this problem at this time”

The infotainment screen on my 2021 GMC Yukon was previously replaced at the GMC dealership, and this will be my second replacement. It has now cracked even though there was only very light contact. This doesn’t seem like normal wear and tear. I’d really appreciate it if the screen could be inspected, as I suspect there might be a manufacturing issue with these screens. I’m quite concerned about this problem because it almost caused injury to my six-year-old. Please understand my worries, I’m sure many other parents are facing similar concerns with these screens. The cracked glass can be dangerous, especially for families with children.
