Electrical system
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 large central infotainment touchscreen (which controls climate control/AC, navigation/maps, audio, backup camera, and all primary vehicle functions) has repeatedly failed by going completely dark/blank without warning on my 2026 GMC Yukon Denali XL purchased new on [redacted]. The screen has gone dark on three separate occasions. First failure occurred prior to [redacted]; vehicle was taken to Champion GMC (7885 W Grand River Rd, Brighton, MI 48114) for repair and returned to me. The screen failed again shortly after. Second repair attempt was made on 06/22/2026; vehicle was returned and the screen failed again immediately. The vehicle is currently at Champion GMC for a third repair attempt as of 06/29/2026. …
Driver assistance
In the 2026 Yukons, almost all physical buttons have been replaced by the giant center touchscreen. When starting my vehicle, about a third of the time the screen will not come on, and can't be turned back on by any means. It will randomly come back on after a few more trips/restarts. This renders several critical systems inoperable. All HVAC does not work, defrosters aren't available, back up cameras and parking assist is not available, and control of any navigation functions or options (ie heated/cooled seats) are not possible. There are no physical buttons for these items, so there are no other options. Voice commands do not function properly when the screen is black, so no option there. After my third visit to the dealership and an open case with GM, they are finally authorizing a screen replacement. We will see if this fixes it. …
This issue affects all vehicles in the GMC lineup. The forward collision alert system is so sensitive that it gives false positives constantly which causes 2 major safety issues with the vehicle. First is that it brakes without warning and when completely unnecessary. The 2nd is that vehicles like mine with a heads up display, have the entire display flash a very bright yellow blocking the field of vision to the front of the vehicle. The system is not able to be disengaged permanently and can cause rear end collisions by braking when no obstacle exists and blocks the ability to see in front of you via the heads up display warning.
