In the 2026 Yukons, almost all physical buttons have been replaced by the giant center touchscreen.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.
On August 9th at 5:30PM roughly, while attempting to park using the vehicle's Park Assist feature, the system failed to function properly-specifically, it failed to detect a pole at the rear of a parking space, did not slow or brake the vehicle, and was not even aware it would contact the pole. It then collided with the pole. Also, intermittently the forward collision alert system either does not alert for similar circumstances as it just previously did. Seem untrustworthy. Scary. GM's product allegation team (PAC) had all of the necessary information to show the system does not work 100% of the time (I have it all on video and submitted that) and they denied my claim and refused to admit a system failure even when given the videos showing the park assist failing to engage properly ON VIDEO.
The car was purchased on 8/15/2026. On November 6th 2026 with 3051 miles on all the gauges, electronic dashboard, gps , climate controls, heads up display failed while car was in driving. There was no way to tell what speed the car was going, the gas level, rpms, engine temperature, etc. Navigation failed, Cruise control failed, I was unsure if the emergency braking system failed. The dealership responded there was over 27 error codes on the car computer. There was no way of knowing if the signal lights were working. There was no prior warning to this failure. The GMC service department at the dealership confirmed the failure and said it needed to replace the radio control module. It took 70 calendar days for a replacement module to be provided, and a new software patch was uploaded after several attempts. …
This is a Post-Remedy Failure of Recall 25V-274 (GMC 6.2L L87 Engine). Following a full engine replacement performed by the dealer under this safety recall, the vehicle has suffered a catastrophic electrical compromise. The vehicle is currently throwing codes P2534 (Low Ignition Voltage) and U3018 (BCM Communication). Safety Hazards: The vehicle experiences sudden loss of power, engine stalling at highway speeds, and total failure of the exterior turn signals (hyper-flash). The AC system has been disabled by the Body Control Module due to low voltage, creating a hazard in high temperatures. This vehicle fits the exact profile of NHTSA Recall Query RQ26-001 and Engineering Analysis EA25-007. …
Transmission appears to be lunging and shuttering. Dealer has indicated that the valve body need to be replaced or the vehicle could leave me stranded or without propulsion while driving. From my research this appears to be related to other safety recall and service campaigns for this type of vehicle and the transmission that I have in my vehicle. Also the camera system doesn't work correctly as it relates to parking assist and collision control. My repair dealership has stated they are having trouble getting GM to cover this repair.
The contact owns a 2023 GMC Yukon. The contact stated that while driving at an undisclosed speed, the engine seized. No warning lights were illuminated. The vehicle was towed to the dealer and was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was repaired. The contact was informed that the repair was covered under an unknown recall repair. The vehicle was released back to the owner; however, the failure reoccurred. The contact stated that the vehicle was idling roughly and jerking abnormally. In addition, the contact stated that the drive to the residence was not a smooth drive. The vehicle was taken back to the dealer, where a technician performed a ride-along. The contact stated that the engine seized three times during the ride along. The contact was informed that the engine needed to be replaced a second time. …
On August 17th, 2026 while approaching a nature preserve entrance at approximately 1 mph, my 2023 GMC Yukon Denali Ultimate suddenly accelerated on its own, without the driver pressing the accelerator pedal, striking a split-rail fence and a tree. Airbags did not deploy. The front collision system didn't issue any alerts about the fence and tree. A GM software update had been installed a couple of days before this incident . In the weeks prior, the vehicle had also intermittently failed to hold side mirror position and periodically failed to deploy the power running boards. I request that GM and NHTSA investigate a possible link between the recent software update and an unintended acceleration event, potentially related to the adaptive cruise control or another driver-assist/body control module.
