2023 GMC YUKON Complaints

I was driving on the highway going about 50 mph and the engine just stopped. It was very dangerous, and I couldn't get to a completely safe spot. I was stuck for 45 minutes there until police could get to my Yukon and help provide safety. I had 2 other passengers in the car. All of us were put at great risk and the surrounding traffic was also at risk. The Triple A towing took over an hour to get the vehicle on a flatbed because they couldn't get the Yukon in Neutral. There were absolutely no warning lights or any weird noises, the car shifted out of drive and would not go back into any gear. I am waiting for the dealership to decide what to do. My main reason for writing this complaint is this is a BIG HAZARD, not only for people who drive/ride in these vehicles but for every vehicle on the roads around them. When they stop with no warning, accidents and I'm sure some with fatalities will happen. This is a critical situation, and these vehicles should all be off the road. My Yukon was in my dealership service for an oil change about 1 week prior to this incident and I had a long conversation about the recall. They said my Yukon looked great and nothing was needed unless I had any problems. Since there have been so many others with the failed engine, ALL vehicles with this recall should be off the road to prevent totally innocent people from being in these dangerous situations. This is preventable if these cars are forbidden on the roads!!! GM must take responsibility before lives are lost due to this negligent reaction of issuing a recall but saying it is safe to keep driving unless there is a problem. If the first sign of a problem is failure with resulting catastrophic outcomes, then just issuing a recall is not enough. This must be addressed, PLEASE. This was a terrifying experience for me and my riders. I have no idea if the police filed the report but they spent alot of time trying to keep everything safe due to this issue.

My name is [XXX] , and I am writing to formally lodge a complaint regarding a serious safety defect in my 2023 GMC Yukon with a 3.0 Duramax diesel engine. The issue involves the transmission valve body, which has caused rear wheel lockup at highway speeds. I experienced this issue at 34,000 miles on my vehicle, and it has been in the shop for over 5 weeks with no estimated time on parts availability. Despite opening a case with GM support, as detailed in the attached email transcript, I have not received a resolution. GM has refused to replace the complete transmission on the vehicle and only offered to replace the valve body. This is unacceptable as the defective valve body has already caused damage to the transmission. I also opened a BBB Auto Line case, which was closed immediately after I denied the offer from the GM support representative. This raises concerns about a potential conflict of interest, as the BBB Auto Line seemed aware of my interactions with GM support. I am seeking a complete transmission replacement with a valve body upgrade kit from NextGen transmission, which I believe would resolve the issue. However, GM has not accepted this offer. I request that the NHTSA investigate this matter promptly to ensure the safety of my vehicle and others that may be affected by this defect. If this issue is not resolved, I will have no choice but to pursue legal action. Thank you for your prompt attention to this matter.

We were traveling eastbound on I 70 around 75mph. We received no prior indication that there was a problem. The display read engine oil hot, transmission shifted to neutral, and the entire vehicle shut down. We lost propulsion and were left coasting on a major highway with no power.

The contact owns a 2023 GMC Yukon. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was contacted and confirmed that parts were not yet available. The manufacturer was not made aware of the issue. The contact had not experienced a failure. VIN tool confirms parts not available.

While traveling away from home with my son my vehicle said push to start. I was able to coast over to the side of the two lane highway and attempted several times to restart my vehicle. After several phone calls between two dealerships, I was told “If you can get it here we can help you”. So I had to file a claim with my insurance to have my vehicle towed to a dealership with only having service while the WiFi was operating. The tow truck kept getting pushed further and further back. Over 2 and a half hours later, keeping my son restrained inside the vehicle for safety, luckily an officer stopped and took myself and my son out of the 97 deg heat all the way to our destination another 2 hours away. From July to September my vehicle was in the dealership service dept waiting on a galactic back ordered 6.2 engine and main fuse repair.

Recall for engine propulsion. Say that there is no remedy yet. I have read the warnings about what may happen and I am terrified to drive the vehicle. GM says to contact the dealer, dealer says to contact GM. No one wants to take initiative. If they cannot fix the car, they should buy the car go back so I can get something different. I have been driving an old car around because I’m am afraid of this one. Please help me.

I’ve inserted the question and their answer: What component or system failed or malfunctioned, and is it available for inspection upon request? Lifter valve number six failed causing it to shatter and send pieces of it throughout the engine along with other debris into the cylinders. How was your safety or the safety of others put at risk? Vehicle had loud engine knock, pulsation of power, had to pull off on main highways due to loss of power over 400 miles away from home. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, engine was serviced by GM dealership in Baldwinsville, NY for over $8,500. Will attach copy of bill. Now is doing same thing, again. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? GM as stated above. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Check engine light flashed, traction control light came on.

My wife was driving in the vehicle with our two (2) infants on Dixie Hwy in Boca Raton, FL when the breaks suddenly stopped working. Fortunately, there was not a lot of traffic on the road at this time and eventually the vehicle slowed down and no one was injured. No warning lights came on. Once the car came to a complete stop my wife turned off the vehicle and started it back up; still no warning lights or anything. My wife drove a little further to get to a safer location (not in the middle of the road), unfortunately the car then completely stopped working and my wife was still stuck in the middle of the road...eventually a police officer (crash inspector) came to the scene and the car was towed to the dealership for repairs.

I was driving on a highway with my [XXX] son and 2 dogs when without any warning the vehicle just stopped and completely went dead. I was unable to turn on the hazards so I called 911, the police came within minutes and surrounded the vehicle to keep us from being crashed into. The brakes failed to work, the hazard lights would not work, the doors would not open other than the driver door. The police had to help remove my child and 2 dogs from the vehicle through the driver door. The vehicle could not be put into neutral so the police had to tow the vehicle from the middle of the highway. The result could have been deadly. The vehicle was completely dead with absolutely no function. After the police towed it to the police tow facility it was then towed to the GMC dealership I purchased the vehicle from. The dealership is Jim Curly GMC in Keyport NJ. The dealership has had the vehicle since Saturday and is claiming to not know what is wrong with the vehicle.

I own a 2023 GMC Yukon Denali with the 6.2L V8 engine. A safety recall was recently issued for this vehicle due to a potential engine defect that could result in sudden and severe failure. However, GM has not provided a remedy, and dealerships are unable to offer any repair or trade-in options while the recall remains open and unresolved. I live in a rural area with limited cell service and long distances between towns. This makes the potential for sudden engine failure even more dangerous. Out of serious concern for my family’s safety, I no longer feel comfortable allowing my wife or our [XXX] child to ride in or use the vehicle. The risk of being stranded—or worse, getting into an accident due to engine failure—is too great given our location and the nature of this defect. I attempted to trade in the vehicle at a GMC dealership to get into a safer and unaffected vehicle, but the dealer refused to accept it because of the recall. This leaves me stuck with a vehicle that has a known safety issue and no solution in sight, limiting both my transportation options and peace of mind. There were no warning lights or prior symptoms before the recall. The issue was disclosed by the manufacturer. A dealer has confirmed the recall is active, but no fix exists. This situation is unacceptable and has real-world safety and financial consequences for families like mine. I urge the NHTSA to hold GM accountable and ensure a remedy is made available immediately to protect consumers who are left in limbo by this unresolved and serious safety defect.
