On November 3, 2026 at the interception of E Edgewood Dr and N Friendswood Dr, at a stoplight. Yukon XL has approximately 73K miles. There were no injuries and no police were called. I was operating my 2023 GMC Yukon XL using the adaptive cruise control system. While approaching a traffic light, the vehicle came to a complete stop as expected. While stopped at the red light, the vehicle unexpectedly began moving forward without my intention, resulting in a collision with the vehicle directly in front of me. The collision caused front-end damage to my vehicle. No airbags deployed. Following the incident, the cruise control system became unavailable and would no longer allow me to activate it.

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 the federal safety agency 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.

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.

On [XXX] there were no vehicles in front of or behind us nor to the sides of us and the roads were completely clear. It was also dark out. Attached you will find evaluation with validation there is a mechanical concern with the vehicle. On [XXX] the extremely unsafe occurrence of emergent braking occurred with skidding tires and the doors locking and unlocking at the same time occurred. This vehicle was completely unsafe to drive.

When driving in a parking lot, due to the design of the cruise control set switch, it is very easy to unintentionally set the adaptive cruise control. Specifically, when maneuvering in a parking lot at low speeds (below 5mph) and allowing the wheel to return to center by spinning in your hands, the cruise control switch which is a dial/lever that sticks out beyond the surface of the wheel, catches on your hand and engages the cruise. This sets the cruise control target speed to a 15 MPH even if you are currently going slower than that. The vehicle then accelerates on its own at a fairly aggressive pace to get up to 15mph. You can of course hit the brakes and cancel the cruise control, but in a tight parking lot scenario this unintended acceleration could easily cause you to strike another vehicle, obstacle, or pedestrian. The cruise control on this vehicle is enabled by default on start up and the single action of hitting the set switch/dial engages the cruise and accelerates sharply even if you had not previously used cruise in that ignition cycle. This seems like a stupid design and dangerous, and would be very easy to fix with a software update to not let the cruise become enabled below 15mph. We did not have the dealer investigate because this appears to be the normal operation of the cruise control system. There were no unusual warning lamps. This has happened several times and also has happened to my wife while driving.

I recently purchased my vehicle and after already transporting my family of 5, including my newborn child for several days, I noticed that my parking sensors were not working and I began receiving a message of my dash that parking assist, rear braking and auto park assist were unavailable. I reached out to GM around 4/4 informing them of the issue and they said they didn't have any recalls or retrofits for my vehicle and advised me to take it to a dealer's service deparment to be reviewed. After having an issue with Simpson GMC of Buena Park of failing to even review my issue for a week, I took it to Penske GMC of Cerritos on 4/17 and they determined that during manufacturing of the vehicle, someone failed to connect the module that controls my parking sensors. They had to remove the front fascia of my vehicle to connect the module for everything to work correctly. This has forced me to call into question the quality control of GM vehicles and also concerns me that a car manufacturer would deliver a vehicle with such gross negligence where a consumer would not know the safety features they rely on to keep themselves and their family safe do not work. GM Customer Service also never followed up on my issue even after calling and emailing them several times, which again calls into question how General Motors operates their business.
