2023 Gmc Yukon Complaints

Owner was driving at highway speeds and the vehicle experienced multiple sudden stops. After consulting with the GMC certified repair facility, the control valve body of the transmission was determined to be faulty and replaced. As a result of the sudden stop at highway speeds, the owner experienced a torn rotator cuff and could have been involved in a serious motor vehicle crash.

Ok so my first issues were with the vehicle stalling while driving in gear. Happened a few times intersections off-ramps etc…and the car would roll to a stop. Luckily no one killed. Again happened a few times. Went to dealer they “fixed”it. Then it happened a couple other times…scary shit…went to dealer then they“Fixed” it again. Happened again I didnt bring it back. By this point I was carrying a 10 millimeter wrench in the glovebox to disconnect the battery so the body computer would reset. Car would start after cycling the power from the battery terminal. And Those were my electrical problems …As far as mechanical problems I brought car in for the recall notice “ the pico test’ . Went for the recall oil change /test/per the recommendations.300 miles later car engine failure at 70 miles an hour on route [XXX] south wife driving. She started crying doesn’t want anything to do with this car. Too many incidents… safety of my family at risk. Please help. FYI i am a mechanic / car elec...

I am filing this complaint regarding my GMC Yukon Denali, currently at Greg Lair GMC in Canyon, Texas, for GM Safety Recall N252494000, NHTSA Campaign Number 25V274, L87 Engine Loss of Propulsion. My vehicle has been at the dealership for over two weeks for this recall, which in my case requires a complete engine replacement. I have been advised the repair may take another 4 to 5 weeks. During this time, neither General Motors nor Greg Lair GMC has provided a comparable loaner vehicle or adequate transportation. This is not routine maintenance, elective service, or damage caused by me. My vehicle is unavailable because of a GM safety recall involving potential engine damage, engine failure, and loss of propulsion. The burden of this manufacturer issue should not be placed on the customer. I was told GM only can reimburse $44 per day for a rental. That amount does not reasonably cover a comparable vehicle to a Yukon Denali and may not even cover a basic rental in the current market....

I am filing this formal complaint to report a series of catastrophic, life-threatening mechanical failures involving my 2023 GMC Yukon. This vehicle has become a weapon on the road, exhibiting erratic behaviors that nearly resulted in a multi-vehicle fatality on a high-speed highway.1. High-Speed Power Loss (Highway Failure while my wife was traveling at 60 MPH in heavy highway traffic, the vehicle’s transmission spontaneously and without warning disengaged and shifted into Neutral. This caused an immediate and total loss of motive power. In a split second, my wife was left piloting a 6,000-pound unpowered projectile in the middle of high-speed traffic. By the grace of God alone, she managed to navigate to the shoulder without being rear-ended. This is a clear "Sudden Loss of Motive Power" defect that poses an immediate threat to life. 2. Unintended Directional Movement (Reverse Shift) Following a total engine replacement—a repair that took over 45 days—the vehicle has now developed a...

I was traveling with my family on the Ohio Turnpike. We were traveling west in our 2023 GMC Yukon Denali when we lost all propulsion and the engine seized. There was no warning lights or other symptoms prior to this incident on May 3, 2026. In fact, I had the vehicle in for the prescribed recall to test the engine for the known defect earlier in 2026. The vehicle passed that test and was given the upgraded oil change to presumably prevent the engine failure in the future. It did not work. Our safety and others on the turnpike were at risk while we were traveling at highway rates of speed with sudden loss of all propulsion. The vehicle was towed that evening to local GM dealer - Yark Chevy in [XXX] . Upon inspection on May 5, 2026, the dealership informed me the engine had seized and would be replaced by GM. They were unable to provide a timeline for this repair. I have the tow expense of $260.70 and now the uncertainty of when I might have a vehicle back. The safe...
