2023 GMC Yukon Recalls, Ratings & Complaints

Incident: October 9, 2026 · Filed: October 23, 2026

Initially the vehicle was slowing at a moderate pace from 75-40mph while on the freeway during [XXX] rush hour. Two days later after getting off the interstate, the rear wheels locked up while doing 40mph on a side street for approx. 1.5seconds. If this had happened on the freeway it would have caused an accident or loss of control. The dealer inspected the vehicle, recreated the issue, and stated the valve body valves were sticking and needed replacement. We never got any warning lights, nor did the dealer before and after they recreated the issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

After the original engine failed the recall inspection, it was replaced as part of GM's recall program at 40k miles. At 50k miles with the new engine (so only 10k miles into the new engine), the engine completely locked up and shut down while my son was driving the car on the interstate. We had to get it towed to the nearest dealership, and two weeks later, we are still waiting on the engine to be replaced again under warranty. I have completely lost faith in this car as I will now be on my third engine in 50k miles, and it is very dangerous if this thing can just shut down again while driving as they clearly have not solved the issue of these failing engines.

On September 20, 2026 around noon while traveling in the left lane on interstate 40W in North Carolina the engine of my 2023 Yukon Denali seized up with no warning. The screens shut off, then turned back on, and as I attempted to avoid hitting anyone or causing an accident on the road, I tried to shift it back into gear and it would not shift back into gear. Unable to use the gas pedal I put my right turn signal on along with my hazards and slowly made my way over to the right breakdown lane carefully to avoid causing an accident. I tried to start the engine again and the screens would turn back on, tell me to push the start/stop button again, then the screens would turn back off and on again and the engine would not start back up. In the breakdown lane I checked the battery connections and a couple other things that I thought might be the issue, but I had a feeling this was the engine issue that caused the safety recall on the 6.2 L GMC engine. My safety, my wife’s safety, and every other vehicle around me was put at risk because of this, and it could’ve ended horribly in injury or possible death. Prior to this, I brought the vehicle in for the safety recall inspection, it passed, and they changed the oil and type of oil filter to “fix the issue“. I used OnStar to set up a tow (which we paid for out of pocket), the estimated wait time was four hours, so we called an Uber (which we also paid for out of pocket) that took over an hour and a half to pick us up due to location on the highway. Vehicle was towed to a dealership and is available for inspection if requested. The next business day, the dealership was unable to get the engine to start and diagnosed with complete engine failure. They began the process of setting up a complete engine replacement. Said it may take 3 to 4 weeks. I am skeptical and think it will take more time. There were zero warning lamps, messages, or noises that could be heard prior to the failure which makes this incident so dangerous.

Vehicle was impacted by the engine recall. After the recall repair attempt, the problem resurfaced and persists. The deal ship has the vehicle and has been down for nearly 7 weeks. I feel unsafe driving the vehicle and asked GM to write me a letter stating the vehicle is safe to drive with this recall. They refused. If this isn’t a problem, why not provide that information. They know they have a problem and won’t help.

Incident: September 22, 2026 · Filed: October 1, 2026

Engine began to reduce RPMs while driving up an incline and was unable to maintain speed. Warnings came on for battery, oil, transmission failure, engine failure. Power ultimately failed and electric finally shutoff after short period of time. Was able to connect to Onstar and they got a tow truck there in 2 hours. I had to hitchhike 30 miles to our residence to get another vehicle to pickup my wife and our 2 large dogs because tow truck unable to transport them. There is no Uber or Lyft in the rural mountain areas of [XXX], and no cell service. Car was towed into service center about 50 miles away, and I was told that the engine had to be replace. But they don't have the parts available after a week. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Incident: August 17, 2026 · Filed: September 30, 2026

The contact owns a 2023 GMC Yukon. The contact stated that the check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed with a solenoid failure. The dealer replaced several unknown components before determining that the engine needed to be replaced. The vehicle was being repaired. The manufacturer was notified of the failure and informed the contact that the vehicle was safe to drive; however, the manufacturer declined to provide documentation stating that the vehicle was safe to drive. The contact expressed concern that the vehicle was unsafe to drive because engine seizure was a common issue. The failure mileage was approximately 41,000.

My 2023 GMC Yukon AT4 is "hard shifting/jerking" during acceleration. This occurs approximately 5 times per week and I am starting to get safety concerns. I have had the transmission flushed (09/14/2026) and then had the diagnostic measured 09/23/2026, with the Repair Order stating "no problem found at this time." During travel on 09/28/26, the violent shift scared my wife and children, so I returned my vehicle to the dealership on 09/29/26. A mechanic traveled with my and the vehicle shifted, but the mechanic told the service representative that the vehicle shifted when we hit a bump in the road. I have been to the dealership three different times to address the concern, but the repair orders state the dealership could not find any problems. I was advised to return the vehicle to the dealership when the "shifting" occurs more frequently. At this time, my vehicle milage is 57340 and I am afraid that my 60000-powertrain warranty is going to expire and I will be forced to pay for a defective vehicle transmission.

Incident: September 5, 2026 · Filed: September 23, 2026

My vehicle was subject to the GM recall involving the 6.2L L87 engine. The dealer completed the required recall inspection, determined that the engine passed, and performed the prescribed remedy for passing vehicles, which included changing to the specified higher-viscosity oil. After the recall inspection and remedy were completed, the engine subsequently failed. While driving on an interstate at approximately 70 mph, the engine failed without any prior warning lamps, messages, or noticeable symptoms. There was an audible warning tone and the instrument cluster displayed a message instructing me to restart the vehicle. I then noticed that the vehicle was in Neutral and the engine showed no RPMs or response when the accelerator was pressed. Pressing the start button did not restart the engine. When I attempted to select Drive, the vehicle displayed a warning indicating that conditions were not sufficient to change gears. The sudden loss of engine power and propulsion while traveling at approximately 70 mph on an interstate created a significant safety risk to myself, vehicle occupants, and others on the interstate. The vehicle could no longer maintain speed with surrounding highway traffic and had to be navigated to a safe location without engine power. The vehicle was towed to the local GM dealer who diagnosed the vehicle with engine failure, stating the engine was seized and the oil filter was full of shredded metal. The vehicle is currently with the GM dealer waiting a replacement engine. I am reporting this incident because the engine failure occurred despite the vehicle passing GM’s recall inspection and receiving the recommended remedy. This raises concern that the recall inspection and/or remedy may not adequately identify or prevent engine failures. The potential inadequacy of the recall remedy is especially concerning from a safety standpoint.
