What 147 owners told NHTSA about the 2024 GMC Yukon Denali Xl 1500

As I was driving the automatic emergency brakes went off and stopped me so hard and fast that I feel like I got whiplash. The seatbelt yanked me backwards, smacking my head against the headrest, I have an instant headache from it and my neck and shoulder still hurt 20 minutes later. It scared me and my child half to death, my heart was pounding and I could have been rear ended. I was driving about 40mph and was in no way in any harm/needing to break (specially this hard) for anything when this happened. This is not the first time my car has unnecessarily automatically slowed down quickly but this is the first time it’s ever been this abrupt and severe. I will be taking my car to be inspected for this issue and if my neck and shoulder still hurt in the next day or two, I will also be going to the doctor about the incident.

We were driving on the highway when the service lights came on along with the check engine light started flashing. The truck sounded like it hesitated a little, but the lights turned off and it drove his normal. We exited the freeway as we were close to home came home, parked it turned it off and turned it back on to test it, and it hesitated to turn on so we took it straight to the dealership where they repeated the issue. We left it there. They did not call me so I went up to the dealership the following day to check on this and I had not heard from them they told me why they were on the test drive that the engine had locked up. My vehicle was a part of the initial recall. They told me that it passed the inspection and they changed the oil to the new oil that was required and now at 12,000 miles my engine has failed

November 12, 2025 - Turned on car and immediately noticed multiple system failure notices and very slow ability to brake. Immediately took to dealership - said battery needed to be re-charged. December 9, 2025 - turned on car and once again immediately noticed multiple system failures and very slow ability to brake. Failures were "Brake System Failure, 43 MPH Top Speed, Forward Collision System Unavailable, Service Brake Pad Monitor, Service ESC, Service Traction Control, Service Sterring Column Lock" Immediately took to dealership. Over the last 25 days in service all the dealership has told me is that their master technicians have looked it over and do not know the root cause. They are waiting for a new technician from GM. They also have another Yukon at the dealership with the same safety symptoms. No issues with the car prior to these two instances of failures. Car should not be driven.

The forward collision automatic breaking sensor has already failed with only 15,000 miles. As well as the backup camera - it has already been replaced once

I have had several time that going down the highway at around 70 MPH with the cruise control on. Know other cars or trucks around me, my car loses power, put on the brakes. If I press on the gas petal, the car will accelerate. Never a warning, scares the heck out of you. Fortunately when this happens I have never had a car or truck behind me. If there would be a car or truck behind me, this could cause a collision for sure. No warning lights comes on. I've told the GMC dealer twice about this. Twice I was told to make another service appointment to bring my Yukon back. I was told that no service tech was available to look at this at this time.

I HAVE HAD PROBLEMS WITH THE NAVIGATION SYSTEM WHERE THE SCREEN GOES BLANK. THE RADIO IS NOT RESPONDING AND SCREEN IS BLACK. WHEN TURNING ON THE SIGNAL LIGHT YOU CAN'T HEAR IT. THE SPEED LIMIT IN MY TOWN IS 25 AND AFTER AN UPDATE FROM THE DEALERSHIP IT NOW SAYS 55. I GET AN ALERT SAYING FRONTAL CRASH NOT AVAILABLE ATLEAST ONCE A MONTH. THERE ARE TIMES WHEN WE ARE DRIVING AND WE GET THE RED ALERT AS TO DETECTING AN OBJECT AND THERE IS NOTHING THERE. PARKING ASSITS DOES NOT WORK ALL THE TIME.

I had just backed the truck out of a parking space (while turning) and shifted the transmission into 'Drive' with my foot pressing the brake pedal (not the gas pedal). When I took my foot off the brake pedal in order to transfer it to the gas pedal the vehicle suddenly accelerated forward without my foot ever pressing the gas pedal. The vehicle traveled forward about 20 feet before I was able to stop it by pressing the brake pedal. I am a retired General Motors Safety engineer and I know I was not pressing the gas (accelerator) pedal when this sudden acceleration event occurred. I believe this type of event occurred one other time while I was driving this vehicle. However, I am not as clear about the circumstances surrounding this previous event.

aside from constant electrical issues with the serial gateway module that gm refuses to replace many safety features fail regularly most importantly this replacement yukon for the 2023 with engine issues also has engine issues and the same 6.2L engine. When leaving my home and or driving on any decent up or downhill road and coasting the vehicle will misfire and trigger the MIL to flash. I’ve taken it into the dealer many times for this and in the end they say it’s a software problem with AFM disabling 5 cylinders. They claim that the geometry of the vehicle along with having 5 cylinders disabled causes the engine to vibrate enough to make it think it’s misfiring. this came from their factory field service tech. they refuse to fix it. they refuse to put this on paper. they told me if I wanted it fixed, I could buy a 2025 instead. this is insanity.

1 Adaptive cruise stopped me several times for no reason as there was nothing on the interstate and the weather was clear. This was very jarring at 80 miles per hour on the interstate created a hazardous and dangerous driving condition as cars were all around, almost was rear-ended. 1a Adaptive cruise started all the sudden when I was stopped at an intersection almost caused a wreck, as soon as I took my foot off the break it speed up, but I was able to veer off and break several more times. The adaptive cruise should automatically go off when the brakes are applied. 1b Cruise control will not activate sometimes (it is intermittent). 2 Sensors do not work properly and do not go off to warn if I have driven to close to something, this has happened several times after I became aware of it and after front bumper was damaged. 2 Garage door opener works sometimes, this means I have to get out unlock the house go shut the garage door and relock the house... very unsettling. 3 Android Auto goes out continuously and will not reconnect even though the maps are still on my phone and everything is setup correctly. This also creates a hazardous condition when driving on the highway in unfamiliar areas causing me to miss turns and unable to navigate through traffic. 4 Seat, adjustable setting does not work when entering the vehicle, only upon exit. 5 Mirrors do not automatically fold when parking the vehicle as they did when I purchased the GMC. 6 Rearview camera doesn't turn off automatically after reverse parking has to be done manually while driving. There are so many issues with this vehicle. I have serious concerns with the safety of this Yukon. I have filed a lemon law with GM on the Yukon. The GM representative Lied in the abrtration stating there was a recall that would fix these issues....The dealer was notified within a week of the purchase but had me wait until GM had a software fix.... They stated the software update should take care of all the issue
