2022 GMC Yukon: engine failure

Filed Nov 3, 2026 · Engine · NV

My brother and I were on our way home from Phoenix to Las Vegas, driving about 70 mph when my 2022 GMC Yukon Denali suddenly shifted into neutral. We pulled over and had to restart the vehicle. We started driving again and a few minutes later the car shifted into neutral for the second time. We pulled over, restarted the car, drove for about a minute and it happened a third time. There was complete loss of control of the vehicle, thus we had no choice but to pull over again. The vehicle completely seized up and would not start again. The car issued a warning stating, “hot oil temperature.” It then issued another warning, stating “low battery,” though all the lights and power were working. The car issued available for inspection at Liberty GMC in Phoenix where I had to have it towed by my AAA. We then had to rent a U-Haul to retrieve the items stuck in the back of my car, which was our reason for the trip in the first place. This situation put us in a dangerous and very unsafe position, as it was dark outside and we had no choice but to maneuver to the side of the road quickly, as cars were flying by on the highway. The engine failure has been confirmed by Liberty GMC, where the car is still sitting and awaiting engine replacement. The vehicle has only been inspected by GMC service at Liberty GMC, to my knowledge. There were no warnings prior to failure. The warnings I mentioned above only happened after the fact.

Vehicle: 2022 GMC Yukon AT4, 6.2L V8 (L87) Mileage at Failure: 159,605 My 2022 GMC Yukon AT4 experienced a complete engine failure at approximately 159,605 miles. The engine seized and could not be manually rotated. The vehicle was inspected by Wallick's Auto Service, which confirmed that the engine was locked up and the oil level was only approximately half a quart low. In July 2025, Green GMC performed the GM recall remedy related to potential engine failure on the 6.2L L87 engine. Rather than replacing the engine, GM's approved remedy consisted of changing the engine oil, oil filter, and oil fill cap. Despite having the recall performed and continuing regular oil changes, the engine failed approximately 15 months later. The most recent oil change was approximately 4,100 miles before the failure. The vehicle was subsequently towed to Green GMC for evaluation. GM declined financial assistance toward the approximately $16,856 engine replacement I am concerned that the recall remedy did not adequately address the underlying engine defect and that my vehicle experienced the same type of catastrophic engine failure the recall was intended to prevent. I am requesting that the federal safety agency investigate whether the recall remedy is effective in preventing these failures.

The engine completely quit while driving on the freeway going 65-70 mph in the number 1 lane. Tried getting the vehicle to restart and nothing happened. Took vehicle back to dealership and they stated the vehicle needed a completely new motor. The same incident just recently happened after they replaced the whole engine, and they are indicating it is the same issue, and claiming will need a new engine.

I am filing a complaint about a serious safety issue with my vehicle. While I was driving on a highway with my spouse and children in the vehicle, the engine began downshifting, the check engine light came on, and an “engine oil hot” warning appeared. The engine then suddenly shut down. With traffic behind us, I had to pull off onto a dirt road in a rural, secluded area. This put my family in a frightening and dangerous situation. The vehicle had to be towed to a dealership. After inspecting it, the dealer told me it needs an engine replacement. This would be the second engine replacement for a vehicle that is less than four years old. I have owned this vehicle for only two and a half weeks and have already had to take it to the dealership twice for major repairs. It is unacceptable to make payments on a vehicle this new that has proven so unreliable, especially when it can shut down without warning while my family is traveling. I am requesting a prompt resolution to both the safety issue and the repeated engine failure.

Sunday XXX, we were riding in our 2022 Yukon Denali with my wife driving on [XXX] at the speed limit of 75 mph when the vehicle stumbled for a moment then returned to normal operation... a few seconds later the engine just died. No drive information center warning or check engine light, no funny noises or catastrophic banging. It just quit running. There was traffic on the highway but with my wife's quick reaction we were able to get off the highway to the breakdown apron without crashing. We called AAA and had the vehicle towed to the GMC dealer (Oxendale GMC) in Flagstaff. We were at this point about 200 miles from home in [XXX] City. On Wednesday, XXX, the service writer called us and informed us the engine was seized and would have to be replaced. We were aware of the NTHSA recall and had taken our vehicle in on XXX to have the recall (N252494000) and at that time we passed the pico test and the oil was upgraded to the higher viscosity and oil fill cap changed. We were sent on our way with no advisory the recall may not have fixed the underlying problem. GM has agreed to replace the engine. We filed a complaint with GM (GM case #XXX) Since this happened, we have been looking into this situation and discovered ours is not an isolated case. A lawyer told us that here have been more than half a million vehicles recalled and an unknown number of catastrophic engine failures just like our, but NTHSA has received less than 1000 complaints. I wanted to make sure that my experience was conveyed to you. An additional note - we special ordered this vehicle new and began to have recurring electrical problems with it shortly after we took delivery. GM offered us a buy-back or a 100,000-mile warranty to keep the vehicle. Since then have had the vehicle serviced at regular recommended intervals by Brdley Chevrolet in [XXX]. We have repair invoices for every service and Recall repair done. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My engine has failed twice. I am now on my third engine. The vehicle stalled while driving on a highway, was in the shop for nearly 3 months and was "fixed" with same 6.2 engine. Eight months later it stalled again was in the shop for 2 months with a new engine. I was informed that they still don't know the issue and they just put the same type of engine. A bandaid was placed in my vehicle and I'm suppose to feel safe in it.

A safety call was issued; the federal safety agency 25V274. GM found my engine needed to be replaced due to the recall. Transwest GMC in [XXX] replaced the engine at no charge in XXX. The new engine they put in, blew up while I was driving. It blew up in June 2026, about 6 months after the replacement was put in. Around 20k miles. Before they would even diagnose the engine failure, they made me provide service records. Which I did and was found to be compliant with their recommendations. They replaced engine again in XXX free of charge. However, now they are telling me that the engine is only covered up until 150,000 miles. At the time of engine failure, I had 127,000 miles on my car. Therefore, I would only have 23,000 miles left of coverage for a brand-new engine they replaced. I am filing a complaint because I am questioning their warranty. I am questing what the warranty is on safety recall. My car is 4 years old, and now I can't rely on it due to mutiple engine failures. It's questionable to me, why they will only cover it to an odometer reading of 150,000 when the engine is brand new. It seems they should cover the part itself for 150,000 miles. Especially when it's a known issue for certain GM motors right now. I am filing a complaint, in hopes that I can prevent someone from getting seriously injured. Also, to protect myself against future engine problems. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

We were driving back from vacation in a 2022 Yukon Denali with less than 40,000 miles on it when our engine completely seized. We were going highway speeds in a remote area. 4 kids were in our car, one of them only 1 month old. We were stranded for 10 hours. Engine needs to be completely replaced. GM is not providing any assistance.

Vehicle lost all power and shutdown coming off the highway. This all happened even after the heavier ow-40 oil was added from the initial engine inspection. Been waiting almost 2 months for a total engine replacement

Engine would tick and burn oil after the updated recall was done. There would be a hesitation occasionally when applying gas when pulling out from stop sign or stoplight. The engine stalled and would not restart. It would crank over but it was a super fast and elongated turn over. We had to call a tow truck and have it towed. The dealership said they found nothing wrong and sent us back out with it. We sent it to another dealership would replaced the auto start stop switch, changed the belts, and did a fuel/valve treatment to clean the fuel system. We got it back and ran it less than 30 days when we picked it up from the dealership after we changed the engine oil, my wife headed out of town on the highway headed to pick up our daughter and the car made it less than 6 miles before it lost power and shut off going 65 mph and almost caused her to get in a wreck. The engine did not turn back over and would not start. Sent it back to the dealership and they found a crank bearing had seized and they replaced the engine. We just got it back but we are not holding our breath since we know so many people here in our small town who have had their engines replaced and we have heard of people getting multiple engines replaced! There fix is not a fix and when these motors go down at highway or freeway speeds it is extremely dangerous. It’s also dangerous for people when they get stranded out in the middle of no where.
