As I was driving on the highway the engine stopped without warning. I was able to safely maneuver the vehicle to the shoulder, but it took me a minute to figure out what happened. There were no engine warning lights in advance of the failure. It was concerning because I was traveling home alone with my 2 dogs and it was very hot. The vehicle had a prior Safety Recall performed regarding this issue, but the engine failed anyway. GM did replace the engine under warranty, but I am hearing that replacement engines are also failing, and I am worried this engine will fail outside the current warranty.

On my 2023 GMC Yukon, XL the infotainment screen freezes and you have no access to any vehicle information, including rearview camera. This issue appeared three months after I purchased a vehicle in 2023 and was taken to the dealership confirmed the issue, but said the resolution was to do a hard reset on the infotainment center. After driving the car for three years and taking the advice of the dealership and resetting the infotainment center every few weeks, the problem escalated and started freezing up at least once a week to eventually doing it every day and the heart reset wouldn’t always work the first time. Dealership eventually confirmed it was a defective radio module. This is a very large vehicle and the rearview camera is an essential necessity to avoid collision.

I got into my car to run some errands. As I drove away from my house, I made a left turn downhill. I noticed vehicles ahead, so I began to slow down. At that moment, I was driving between 20 and 25 mph. When I tried to brake, my brakes failed and started flashing a brake failure warning light. I kept pumping the brake pedal, and eventually, the car slowed down and came to a stop. I turned on my hazard lights, and immediately returned home. My nephew and I were both in the car. Our live flashed in front of us. Thankfully, there were no vehicles directly in front of me or pedestrians. This could have turned out to be the worst day of my life if anyone had been injured.

The panoramic sunroof on my 2023 GMC Yukon Denali Ultimate XL spontaneously exploded while driving westbound on I-20 on March 13. There was no impact from road debris, no vehicles ahead, no overpass, and no external cause. The failure sounded like an explosion or gunshot. Tempered glass shattered with the sunroof in the closed position, showering the interior with glass fragments. Five occupants were in the vehicle at the time. No injuries occurred, but the sudden explosive noise and shower of glass created an extreme distraction and safety hazard while operating the vehicle at highway speed. The incident could easily have caused a loss of vehicle control on the interstate. The component that failed is the factory-installed panoramic power sunroof glass, standard equipment on the Denali Ultimate trim. The vehicle was taken to Lugoff Chevrolet for inspection. The dealer confirmed the glass failure and submitted a request to GM for warranty or goodwill coverage. GM offered to cover only 10% of the repair cost, characterizing the failure as an out-of-warranty wear issue despite the spontaneous nature of the defect. There were no warning signs, cracks, chips, warning lamps, or any indication of a problem prior to the failure. The sunroof was closed at the time. The vehicle has been dealer-maintained with no modifications to the sunroof or roof structure. This is a known industry-wide defect. NHTSA has previously investigated spontaneous sunroof shattering and documented over 4,000 complaints. GM has acknowledged awareness of this issue in other GM vehicles and previously issued corrective actions for sunroof glass on the Buick Regal and Chevrolet Cruze. Other GMC Yukon owners have filed NHTSA complaints describing identical failures. The failed sunroof glass and vehicle are available for inspection upon request.
