Warnings Problems of GMC Yukon

What component or system failed or malfunctioned, and is it available for inspection upon request? the vehicle experienced a malfunction associated with a failed over-the-air (ota) software update affecting electronic control modules. The (ecm), (bcm), and related electronic systems appeared to lose stability during operation. The vehicle attempted to reboot while being driven and displayed multiple system warnings. The vehicle is currently at the dealership and is available for inspection upon request. How was your safety or the safety of others put at risk?while driving, the vehicle began malfunctioning and attempting system reboots. The dashboard flickered, warning lights, and the vehicle exhibited unstable behavior. During a prior event, the vehicle experienced unintended acceleration and abrupt deceleration. This created a risk of loss of vehicle control, particularly in traffic. I have small children in this vehicle, and the unpredictable electronic behavior while in motion posed a significant safety concern. Has the problem been reproduced or confirmed by a dealer or independent service center? the dealership confirmed that a previous event was caused by a failed ota software update. The vehicle has since malfunctioned again while driving and has been taken back to the dealership for further inspection. The dealership has acknowledged module instability and opened a tak case with the manufacturer. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? the vehicle has been inspected by Gmc1 dealership. A case has been opened with gm customer care. No police or insurance reports. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? 9 days prior to the first major malfunction, the check engine light illuminate. On April 1, the check engine light re-appeared and the vehicle attempted to reboot again while driving.

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.

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. However, my previous explanations from gm pointed to a nebulous future software release, with no date or detail.

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 image module system has completely failed and never worked in the Yukon. Then it would brake while still accelerating.

While driving in downtown boston in heavy traffic (stop and go) braking did not stop the vehicle when removing my foot from the brake and reapplying and the braking was extremely hard, the vehicle nearly collided into the vehicles in front of me. This issue persisted continously for the duration of travel. The issue was not found using the VIN provided. This issue must be resolved ASAP. This incident was not the first, after owning the vehicle for several months this issue is a major safety issues, specifically when my new young adult drivers use this vehicle. Please help me resolve.

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.

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.

On 5/22/2025, I filed a complaint with NHTSA, complaint number 11662650. In the complaint, I reported issues regarding safety concerns that began around October 2023 and were shortly after reported to GMC. Some of the reported issues were concerns with oil consumption due to warning lights coming on; parking warning sensors intermittently coming on; and what appears to be suspension issues as there continues to be a knocking, cracking, and snapping noise coming from the front suspension when making a left or right turn, along with a bumping when in motion, among other issues such as infotertainment that continues to be an issue. Recently, we took our SUV to a GMC authorized dealer since it was still under warranty and these issues continued to persist and it is getting worse. The vehicle was left around 5/28/25 and picked up on 6/17/25. However, less than a couple of weeks after, we started experiencing the same issues with the suspension as the knocking, cracking, snapping, and bumping is getting more obvious and worse, and it appears is affecting the steering and alignment of the SUV. Please update this information as there is a major concern with safety of the vehicle. Attached are some of the service records related to these issues. Should you need any additional information, please advise. Thank you.

My wife and I purchased a new 2022 Yukon around July 4, 2022. The vehicle came with a 36k or 3 years warranty. Around October 2023, we experienced several safety concern issues with the SUV and around 11/01/23, we reported these issues to a GMC dealer. Around 11/01/23, we took our SUV for service at an approved GMC dealer and reported issues with the steering suspension such as a knocking, snapping, and cracking sound when making a turn, and a bumping when making a u-turn or left turn into a parking spot. We also reported issues with the parking and key sensors. We were informed the issue was fixed and that some suspension bolts were loosed and needed to be torqued. On 1/29/24, we took the SUV back for some of these same reasons after other dealers declined to take our SUV under warranty. Once more, the issue was temporarily fixed. We have now scheduled another appointment for these same reasons of knocking, cracking, and bumping when coming from the front suspension and when making a turn or u-turn. In addition, we are now experiencing oil warning lights for a second time as oil comsumption. We believe these are serious safety issues, especially with any potential failure of the suspension under rain, fog conditions, and the lack of resolution and wonder if other similar issues have been reported or experienced by similar drivers of these vehicles. Attached find copies of the work orders. Should you need any additional information, please advise. Thank you.

My vehicle has software that controls the rear gate, cameras, and my safety features for blind spots—seat buzzer to warn of collisions and voice activated phone system. I recently had a safety recall involving my back wheels locking up during driving. I had the recall done by power Chevrolet and it affected my cameras, which I noticed were longer accurate immediately after leaving the dealership. My seat buzzer kept buzzing warning me of a collision due to the cameras inaccuracy. I am unsure if it affected my blind spot warning but my car was unsafe to drive as the safety features fill in many blind spots in this big vehicle. Additionally I had been having issues with my back gate opening when it should not resulting in two stops to close it— one in costco and one on [xxx] outside of philomath, oregon. These are safety issues. To get the software issues resolved, it cost an additional $210 for the updates and my back gate is still not fixed and no solution is offered. My fear is that people will be unaware their cameras or safety features are no longer properly calibrated and hit something or even worse, be unable to pay for software updates to make these features functional resulting in more crashes. I was unaware of the software updates ( I did all updates GMC pushed) needed to be done and this just continues on with more software updates to be released requiring future payments. I bought this car new and this was not disclosed or even discussed. GMC can push down updates that make other updates necessary and be an unending source of revenue for them. Oregon just passed a right to repair law but cars are exempt. This will result in unsafe vehicles on the road. My oil change cost me $350 with $210 the software updates. What were these safety related updates not done as recalls? information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The 2022 Yukons were sold without certain parking sensors installed, with the promise of a retrofit as soon as the sensors were available. I purchased this vehicle in may 2022, and am still waiting on a parking sensor retrofit. I have called GMC several times about this chip, and have been told they're still waiting, even though they continue to produce additional vehicles. I bought the vehicle with the expectation that the parking sensors would ultimately be repaired; how long will you allow GMC to delay these retrofits?.

When turning left the vehicle locks up and turns off, after that messages about the parking assist and versatrack starts popping up.

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.

Brand new vehicle, at about 5k miles the backup camera went out in April 2023. It is not decemeber of 2023 and I have no had any sort of resolution. I have 3 children ages 2, 4 and 5 and it is very concerning for me and my wife to not have a backup camera especially at night.

Unknown 4 times in the past 6 months, while parking the vehicle (turning into a spot, left or right) or slowly turning to pull up to a security code box, the car completely begins to lose power in drive, and has lost power while in drive twice. The dash begins to flicker to the point that you can't decipher which error codes are showing up. Most recently, the trailer brake service message was on before it died. We were not towing anything, did not have tow mode on, or anything like that. The parking sensors were on for all these instances. . . Regardless if we were parking or not. I can't confirm if that is the issue or not. It was pretty dangerous when I was pulling into my parents driveway along a busy road when the car did this before I was completely off the road. . . With my 3 young children in the back 2 rows. I know the battery is new. I did have the dealer look at the brakes about a month ago, because I felt they were soft. They said they were fine. They and myself checked the reservoir for brake fluid low. Was in normal range. Starter was replaced in March time frame. I feel this is related to the factory trailering system wiring harness or something.
