My wife was driving the vehicle down a major highway in Tulsa and it immediately shut down and started slowing down. She was in the left hand lane had to cross 3 lanes of traffic with a dead engine. Luckily she wasn-??t ran into because traffic was very heavy. This could have resulted in injury or even worse. She made it off the highway by about a foot and had to sit there for 30 minutes before I could get there. The vehicle had to be towed to a dealership and they just confirmed that the engine was blown. The vehicle only has 70,000 miles on it and has had regular oil changes.

After the vehicle was serviced with a fuel injection cleaning and an oil change (by a GM dealership), the vehicle lost about 5 miles per gallon while driving and has not improved since.. I brought the vehicle back to the same dealership and complained. Another fuel injection cleaning was performed, but it did not help. It has been about 3 months and nothing has improved. I use 93 octane, TopTier gasoline.

On January 23, 2025, at approximately 7:00 p.m., I was traveling on I-10 when, without warning, my engine shut off on my 2022 GMC Yukon, and I rapidly lost speed. We managed to pull the vehicle off the road. This was extremely frightening since there was traffic on I-10.

- Deming, NM, USA

Engine locked up while driving down the highway, no warning or anything. Only 19,000 miles. This happened on November 30th 2024 and Yukon is still in the shop. They have installed 2 motors, which all have failed.

- Dexter, MO, USA

Engine locked up / froze up while driving 75MPH on interstate i-10. Vehicle is now in the shop awaiting a new engine. It will probably lock up as well, finding there is no known guaranteed reason for this engine failure. Dealership provided a junk rental and said it would be a few months before repair is complete. My towing bills were not paid by GM. My insurance had to pay which is simply not right! I'm sure they will pull a mystery motor off the shelf and hope for the best... Very dangerous!

- Harrison Township, MI, USA

The 6.2 L engine Yukon spun a bearing caused my car to shut down in the middle of the road barely got off the side. Lucky that we were not at highway speeds and nobody rear ended us. When I got to the dealership they did not care that this occurred and GMC customer care did not even acknowledge about the safety of us on the road when this occurred. At this point GMC nor the dealership has an ETA on replacement.

On February 21st when driving on the highway at highway speeds, the vehicle on its own shifted into neutral and I was forced to pull over onto side of the road before the vehicle allowed me to put back into gear of drive. Upon getting back onto the highway, I noticed and heard the sound of the motor very different and louder than normal, I immediately pulled over to the nearest exit to where the vehicle shut off on its own and did not allow me to control the vehicle. I was stranded at the exit where a number of other vehicles and 18 wheelers were trying to exit, I called the local PD, to come assist with traffic control and had to wait on tow truck to have vehicle towed home, then next day towed to local dealership. Received a phone call from dealership days later that the technicians were able to fire it up, but it immediately lost oil pressure and motor locked up, I am being told by the dealership that the motor will need to be replaced, it is covered under warranty BUT I am being given no timeline as to when it can be fixed.

We were driving down the interstate at around 70mph and without warning - the vehicle shut off. The engine stopped running and the vehicle put itself in Neutral. The headlights and electrical all shut off and the only message on the display was to push start to restart the vehicle. Luckily, we were able to safely maneuverer out of traffic without being hit by other vehicles. Our vehicle was able to be restarted once we came to a complete stop and put the car in park. We are having he vehicle towed to our local GMC dealer to have it evaluated. The issue only happened one time.

- Mills River, NC, USA

My vehicle was 8 months old and it completely stopped with no warning going down the interstate, I was in the left lane and the vehicle locked up, engine and all leaving me stranded in the left lane on a busy interstate. When the engine quits, there is absolutely no way to get the vehicle into neutral to get it to a safe location. When this happened I was almost hit by an 18 wheeler. After having the vehicle towed to the dealership, they informed me the engine was seized. It took 3 months to get an engine from GM, they finally got the engine in, started it up in the shop, it apparently ran for about 15 minutes before losing oil pressure. At that time they shut the vehicle off, pulled the oil filter, found metal shavings in it and GM told the dealer to order another engine. But there were no engines available. The dealership finally notified me 3.5 months later that they finally received an engine and were working on installing it. I finally got my vehicle back after more than 6 months at the dealership and it was on its 3rd engine. I drove the vehicle for almost 2 years before the Same thing happened, the vehicle locked up on the highway and I had to have it towed. It has taken the dealer over a month to diagnose the problem and called to inform me the engine had seized up again. This will be the fourth engine in a 2022 GMC Yukon AT4. Besides the issue of the engines going bad, it is a severe safety issue that the vehicle will completely lock up on the highway with no way to move it. Twice I have almost been in a serious accident because of this.

Car shut off while driving down the interstate at 70 MPH. Barely got to side of road. Two children were in the vehicle. The safely of all in the vehicle were at risk. Car would not restart. Had to be towed. GMC dealer told me the motor needs to be replaced. It is the 6.2L.

- Smithton, IL, USA

Engine seized on the highway doing 80mph with my three young children in the car. The safety of my entire family was at risk! Luckily made it to the side of the road safely, but was freezing in the rain and snow with a completely dead vehicle. The vehicle had been in for service months earlier and they detected a -??bearing-?? issue and had it for 2+ weeks to repair. I can-??t help but think these two incidents are related. No warning signaling that the car was going to die - it became very clear we were coasting while trying to apply the gas.

- Paducah, KY, USA

The engine started making a rattling sound. Brought it to the dealer and they told me the engine is bad and it needs a new one. They told me this issue with lifters and the fuel management system is a common problem leading to internal metal components breaking. My car has been with the dealer since 12/30/24 and I was told this week from the dealer the problem is so big there aren-??t any engines available and they have no idea when I-??m getting it back. When I initially dropped it off, they said approximately a month. Now they are saying they don-??t have a clue.

- Watertown, CT, USA

Sudden loss of power while driving approximately 60 MPH. Dash saying "press engine start". The vehicle lost all functions while moving at about 60 mph with zero warning signs. After diagnosis with the GMC dealer, crank bearing failure led to complete motor loss. The concern was there was no warning signs, noises etc. that would allow to get the vehicle to a safe location off the road. We were lucky we were going straight and not on a corner and able to coast to a wide enough location to get the vehicle off the main lanes of traffic.

I was driving on an expressway in Chicago heading to work at 5am on [XXX] morning. While driving my engine shutdown and I lost engine power to my vehicle while doing 70mph. There was no warning, no warning lamps and no noise to indicate there was any issues. The vehicle just died while I was driving. I had to coast to the shoulder with traffic all around me. Luckily I was able to avoid other vehicles and they were able to avoid me when they realized I was having trouble. Though there was a very close call where I almost got into an accident. When I pulled onto the shoulder the vehicle completely shutdown. It would not restart. I had to call a tow company to have my vehicle towed to the Dealership. Luckily, I was able to find one nearby that was open at that time on Christmas Eve. The dealership mechanics went over my vehicle and determined that I had complete engine failure. The bearings on the bottom end of the engine spun out. I now need a complete engine replacement along with whatever other components were also damage. This incident was a major safety issue. I was luckily that I did not end up in a major accident due to the loss of complete engine power. This is a major issue that needs to be looked into and GM needs to be held responsible for not only my vehicle but all others that this is happening to.
