ENGINE
We were driving from another part of town back to our home on a very busy road, when our 2024 Yukon Denali Ultimate stopped working. My wife, who was driving, was able to turn onto a side road and stop the vehicle on the side of the road. The SUV would not start at that point. It was towed via a flatbed trailer to Ray Miller GMC, where it was determined that the engine had seized. I bought it at Howard Bentley GMC. They had it brought to them. GM only is offering an extended warranty even though the engine is being replaced, and the vehicle has inherently lost value. Luckily, Howard Bentley is giving me my money back towards a new 2025 Yukon AT4 Uktimate.

FUEL/PROPULSION SYSTEM
Fuel line rubs between cab and tank making a hole. Fuel pours out on when driving or running. Huge fire risk. Glad I caught it before the car burned up with us in it.

ENGINE
On [XXX], at approximately [XXX]., I was driving down a highway and my vehicle engine just stopped. The dash went blank, I lost power and steering and there was no warning. I had enough momentum to partially stop on the shoulder of the highway but part of the vehicle was still in the flow of traffic. It was a dangerous situation for sure, especially since I had my [XXX] son in the car with me. I had the vehicle towed to the dealership where I purchased it, they said it was a connecting rod failure and I would need a new engine. This was on [XXX] and I still do not have my vehicle, they said the engine was on backorder. I have been in regular contact with GMC customer service and they have been largely unhelpful and unwilling to explore any other option that me just waiting for an engine to come it. I am now in my 9th week without my vehicle. The way they have treated me is unacceptable and they have not even acknowledged the danger that this defect put me and my son.

ELECTRICAL SYSTEM, ENGINE, VEHICLE SPEED CONTROL
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.

ENGINE, UNKNOWN OR OTHER
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.

ENGINE
On Jan. 19, 2025, while driving home, I started hearing a loud knocking noise from my engine. Lucky I was still on residential streets so I was able to safely pull over to a parking lot. I was planning to drive the 40 miles home on the freeway when my wife said it might not be safe. That was when I decided to drive to my sister's house. Only when I pulled into the drive way the check engine light finally came on. The next day, I had the vehicle towed to the dealership and they diagnosed that I needed a new engine. They did not go into specifics as to why I will need a whole new engine but they did tell me that this was common and that they had other vehicles waiting for an engine also. My vehicle has been sitting there since.

ENGINE
Traveling at 65 MPH on highway when electronic dash went completely blank, audio on car stopped as did the engine! Steering of vehicle remained in tact so I was fortunate to be able to "coast" to the side of the highway. GMC Dealer has confirmed a total engine failure and stated they will need to replace the entire engine. There were no prior warnings, symptoms or problems with my vehicle prior to this incident.

ENGINE
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.

POWER TRAIN
Transmission failed at 90,100 miles. Left me stranded in middle of a busy intersection as I was making a left turn, it was like it was in neutral no matter how much I tried to accelerate. Very dangerous situation, scary and helpless feeling as cars approaching and I could not get out of their way. Near miss accident. This should not be happening at this low mileage
