The center screen (infotainment), which shows controls for cabin climate (a/c, heat) and many more functions of the vehicle fails to turn on at random times. It is available for inspection. The external air temperature is in the upper 90s; temperature inside the car’s cabin is easily 115 or higher. This makes safe operation of the car not possible. Additionally passengers cannot occupy the vehicle safely at these extreme temperatures. The problem has been reproduced by dealers. Unknown whether the components have been inspected by the manufacturer. No warning lamps or lights.
I lost all sound on my 2026 GMC Yukon xl with only 150 miles on it. Apparently this is a common issue that needs a recall.
While operating the vehicle, I began to hear a metallic grinding noise originating from the center of the engine compartment. The sound was clearly audible within the cabin. Approximately one mile before the vehicle ultimately failed, the engine began to malfunction. As I slowed to a stoplight, the vehicle started to shake before shutting off abruptly and entering a coasting state. All electrical systems powered down and the vehicle would not restart. Shortly thereafter, heavy smoke began to emit both inside and outside the cabin, visibly coming from the hood and through the air vents. There was also a distinct burning odor. I attempted to restart the vehicle multiple times without success. The dashboard displayed the message: “conditions not suitable to shift. ” due to the vehicle becoming disabled on a curve and posing a safety hazard, I contacted the sheriff’s office for assistance to prevent a potential collision. Upon their arrival, it was noted that the engine compartment and hood area were exceptionally hot, particularly where the smoke was originating. The dealership has since confirmed they have also been unable to restart the vehicle. The vehicle has been inspected by the GMC dealer and is currently pending further evaluation by a gm-certified mechanic to determine the root cause. Prior to this incident, there were no warning lights, system messages, or other noticeable symptoms indicating an issue.

The failure is heat-related and intermittent: the screen functions on cool days, and on hot days it fails the vast majority of the time, unpredictably, after the vehicle heat-soaks in the sun. When it fails, the entire screen goes dark and I lose the backup camera and surround-view cameras, all hvac/climate controls, audio, navigation, and most secondary controls. Steering, brakes, and engine are unaffected. This creates two safety hazards. First, loss of the rearview camera image eliminates rear visibility when backing — the exact risk fmvss 111 is intended to prevent — raising the chance of a backover crash. Second, loss of all climate control in extreme heat endangers occupants in north carolina summer temperatures, and a blank, unresponsive screen is a driver distraction.

On 3/14/26, on I-75 in troy, michigan at 70mph the vehicle, with 4000k miles on the odometer completely shut off. I pushed to restart the engine and it would not restart. My whole family was in the car and we were on a curve. I was able to coast to a flat shoulder. The vehicle would not restart or shift out of park. Onstar took seven hours to tow the vehicle. The dealer is installing a new l87 6. 2l engine. I do not have the vehicle back yet. I received an economy car as a loaner. The dealer says gm will not extend the factory warranty despite the engine replacement. My family could have been easily killed.
The infotainment screen which controls the a/c, heating, defrost, cameras and all other info for the vehicle does not come on in th vehicle. This began happening after owning the vehicle for 3 days. After taking to the dealer, delray GMC, we were informed by the service personnel on our second trip in for the recurring problem that general motors knows this is a problem and are selling the vehicles with this factory engineering design defect and currently there is no repair. Living in florida this is a problem in the extreme heat with no a/c, being from illinois, when we return this will be a serious problem, not knowing if we will or will not have access to heat, cannot control the temperature or the defrost on the vehicle and having a infotainment center that is non functional. We consider this a hazard to our safety and feel that gm is fraudulently selling consumers defective vehicles knowing this may be a safety hazard.
