2023 GMC YUKON Complaints

The contact owns a 2023 GMC Yukon XL. The contact stated while driving 86 MPH in the middle lane, the vehicle shut off on five occasions. The vehicle was restarted, the steering column was locked, and the brake pedal was depressed but failed to respond. The contact stated that the rear axle had disengaged. The suspension leveling system had failed. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed that there was an electrical failure. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was 39,000.

Windshield wipers periodically fail to operate when turned on. This is but extremely dangerous because it's been impossible to determine what the cause is. When the wipers stop working, I adjust the speed from the intermittent settings to LO and HI and there is no change. I can turn the RainSense setting to OFF and there is no change. The wipers stop working and then after a few minutes, will turn back on. I have taken the vehicle to the multiple GMC dealers for service and they cannot diagnose the problem because it only occurs periodically. They refuse to change parts in an attempt to fix it. I have called GMC Customer Care and their response is "take it to another dealer". I have showed the videos I have captured of this dangerous situation and the dealers don't care. I have the videos and can share (but this site doesn't allow upload of videos). This is extremely dangerous. The wipers have cut out at highway speed in torrential downpour multiple times.

Urgent Appeal for Investigation into Braking Capacity Discrepancy Dear National Highway Traffic Safety Administration (NHTSA),I am reaching out to bring a critical matter to your attention regarding the braking capacity of my diesel vehicle, which has not been adequately addressed despite multiple notifications to the service center.The primary concern I wish to highlight is the inadequate braking capacity of my diesel vehicle, which poses a significant safety risk. This concern is especially troubling when compared to my similar gas-fueled vehicle from the same manufacturer, which exhibits notably superior braking performance. After discussing this matter with the service center, their response was that the braking performance is considered normal for my diesel vehicle. However, the evident disparity in braking effectiveness between my diesel vehicle and the gas-fueled one suggests otherwise. This difference is particularly concerning given that both vehicles utilize the same brake system, despite the diesel vehicle's higher weight. In light of these circumstances, I urgently request NHTSA's intervention to investigate this matter promptly. The inadequate braking capacity of my diesel vehicle presents a tangible risk to road safety, affecting not only myself but potentially all drivers on the road.It is crucial that corrective measures are taken swiftly to address this issue and ensure the safety of all drivers. Your prompt attention to this matter is greatly appreciated.Thank you for your immediate action.

On March 15, while driving on a busy road our vehicle STOPPED from catastrophic engine failure without warning which put my family and I instantly in danger and nearly got us killed. Due to the high traffic where it stopped we were scared to stay in the vehicle and also scared to exit it .. so we contacted the police before calling a tow truck. When the police arrived, they parked a car in front and behind us and put their flashers on to make us somewhat more safer... we had the vehicle towed to the local dealership and contacted the actual dealership where we purchased this brand new vehicle with zero miles that was about an hour away and they sent soneone to get the SUV . Once they ran a diagnostic they discovered metal shavings in the oil and said it needed a new engine! What's alarming is that after hearing this we started googling terms like "Denali engine failure" "Cadillac ecalade engine failure" and discovered a huge amount of consumer complaints from other GMC customers on forums with their brand new GMC vehicles with little to no mileage and ALL had the metal shavings in the oil and shockingly needed new engines! FYSA- All complaints are on the 6.2 engines specifically. This is a huge safety issue as these vehicles are stopping in the road without warning. If someone doesn't do something I'm afraid someone is going to get killed. Please look into this and help us. We paid over $100k for a vehicle we no longer can trust. We were not given a police report but I'm sure the information about this incident is available by FPD since they were called and remained on scene with us for nearly an hour waiting on the tow truck. The dealership was great by the way, we do not blame them as we feel they are victims too. This is a GMC problem who are knowingly building and selling unsafe SUVs with the 6.2 defective engine that's literally stopping without warning while driving.

I will prove it to you with other owners, same problem, where the vehicle just shuts off.

The vehicle was crawling to a stop in preparation to park in front of my garage door. When I move my hand across the steering wheel, my hand must have come in contact with the toggle/scroll for the “resume speed” function of the cruise control. The vehicle abruptly began accelerating towards my house. I was able to press the brake pedal to deactivate and stop the vehicle safely. I note that in the past week, perhaps even two, the cruise control has not been used. The vehicle is driven 2-4 trips a day.

Riders with long hair is getting caught in the "DENALI" emblem embedded in the seat back of the front seats. This has been addressed with a GMC dealer and they stated the seat emblem is within specs as they put it. This is noted on the attached work order regarding this

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.

Brand new vehicle, at about 5k miles the backup camera went out in April 2023. It is now December of 2023 and I have not 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.
