ENGINE
We received a notification that our 2023 GMG Yukon Denali Ultimate engine needed to be tested as a part of a recall. We took the vehicle to our local GMC dealership. The engine was tested and determined to "pass". The "pass", we were told, meant that we did not need a new engine, just thicker oil, and that the engine was safe. Mind you, our car was a custom order, took 8 months to receive, and is not even 3 years old. The vehicle is my everyday driver. I have two kids and live in a large city with a lot of traffic. A few months after it was determined to "pass", I was driving with my kids and dog in the car. The abruptly stopped, putting itself in neutral. Luckily, I had just turned off of a major interstate and onto a side road. The car would not start or move out of neutral leaving me and my kids in the middle of the road. It now needs a new engine. Prior to this issue, the battery died a few weeks after we took delivery of the vehicle. SAFETY!!!! If this happened just a few minutes prior, I would have been on a major interstate in one of the nation's worst traffic cities. My car would have abruptly shut down absolutely risking other cars hitting my car. All of this could have been avoided if GMC recalled AND REPLACED all impacted engines. The GMC service tech admitted that they (GMC) knew it was a "band-aid" that wouldn't work. GMC is putting lives at risk. In addition, we now have a vehicle we paid more than $150k for that is virtually worthless.

My vehicle has experienced total engine failure. The first time occurred in 2024. The dealership replaced the engine with a new one. It has now failed for the second time. This time I nearly crashed as the vehicle went from 65mph to 0mph in 5 seconds. There was no warning and my vehicle is serviced regularly by the dealer I bought it from. The dealer has not yet responded with how they will resolve this issue.

ENGINE
Loss of power while driving, no warnings, no lights on dash, no unusual noises, and no codes. The Yukon just randomly went into neutral while driving 65 mph and "Press Start Again" popped up on the dash. I struggled to get the truck to the side of the road safely. After getting the truck into park it started back up, and I was able to make it the 3 miles home. I scheduled it to go into the dealership as it still is making no noises, and had no engine light or codes, about 2 miles from my house it shut off again while driving, only this time when it restarted it now has a ticking sound coming from the engine however no warning lights and no codes being displayed. I am reporting this as I believe it falls under the open investigation EA25007, although it clearly is the same failures others have experienced on models that were included in the recall 25V-274. I am also attempting to contact GM as my vehicle is no longer under the powertrain warranty that was not extended for the vehicles that were not included in the recall.

ENGINE
Car driving down highway at ~70 MPH with wife and our three young kids. Engine spontaneously shut off while driving. Electronic and other systems continued to function (power steering, brakes, lights, screens etc). Dangerous situation but was able to stop car in shoulder. Tried turning car on and off but car would not restart. Police were notified but did not come. Tow truck came and tuck car to a GMC dealer (GMC Danvers). Next day when techs arrived at dealer, they were able to start and drive car without issue. There were no present or stored fault codes other than a warning pertaining to the battery. Battery has been replaced and GMC is stating car is now safe to drive. Because issue could not be replicated by dealer and car did not store any fault codes despite the engine shut off, we question whether the issue has been correctly identified and repaired. We noted to GMC that the issue experienced was the same issue associated with the recent recall (for which the car was previously serviced). At this time we do not believe the work GMC performed under recall properly addressed the known engine shut off issue. We requested GMC and dealer perform another picoscope test to conform no issues with crank shaft. GMC refused to perform the service, despite us offering to pay for the test out of pocket. GMC is not offering any additional solutions to identify the cause of the engine shut off issue.

In September of 2025 my 2022 GMC Yukon AT4 6.2L V8 passed the test for the 25V-274 recall. The dealer did necessary fix with the higher viscosity oil. As of January 6th my Yukon has been in the shop with engine failure. My Yukon needs a new engine, so clearly the fix with using higher viscosity oil did not work.

ENGINE
Engine had a burning smell and cranking sound. It lost propulsion, no indicator lights were illuminated and the car shutdown while driving. This is a recall item. It passed the recall inspection. I also had it inspected prior to leaving for my trip 2000 miles from home. Im currently stranded and awaiting my options. This is very unsafe, the engine failed while I had no service within 50 miles. Freezing temperatures at sunset. Im being told that my towing and rental car may not be covered. GM told the dealership to do the oil repair first. They covered up the failure. I also had an issue with electrical items after the purchase and that issue is why my alert lights never came on even when the vehicle was Inoperable.

ENGINE, POWER TRAIN, VEHICLE SPEED CONTROL
We are located in Henderson, NV and we were driving on the freeway in a construction zone with no emergency lanes when the vehicle lost all power to the engine going the speed limit. The engine had seized up which is a known problem with the 6.2L GMC motors. We have done all the recalls recommended by the manufacturer. The engine seizing, locking up , put our family in danger . We were luckily enough to be close to an offramp where people in other vehicles barley let us over so we can pull off the road or we would of been stuck in the middle of the highway with cars flying by us with little kids in the car. This is unacceptable and as much as this happening and GMC not fixing the issues, people are going to get hurt or killed. IT IS A HUGE SAFETY CONCERN! . ThIS is a known issue with these motors and problems and GMC is putting bandaids on the situations when lives are in danger. Our truck is a 2023 GMC Yukon Denali with only 53k miles on it

ENGINE, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
I have a 2021 GMC Yukon with 74,000 miles I was recently told I need a new transmission.I am am trying to understand why a car that is 5 years with all the services done by Lehman GMC in North Miami would need a new transmission they have been servicing this car and no one mention anything breaking down of need of repair until now. I spoke with the service manager Franklin and he stated to me another client had the same issue and he flush the transmission just like I am doing today and it only worked for a short time and afterwards he had to replace the transmission. I feel this is a problem with these models and GMC don't want to address it. they just want the customer to pay for the repairs. Now I spoke to the Manager and the salesman that sold me the car and nicely told me he was sorry and he could get us out of this into a 2026. Now why would I buy a new car if they cannot get the 2021 right. I have included my invoice below I feel some one should look into this I feel this is a recall matter and GMC is trying to pass the buck.

POWER TRAIN
I live in Alaska. It was -13f. We were out and about and when I tried to leave and back up, the vehicle would not go into reverse. If it hadn’t been for a passing motorist my daughter and I would have been stuck there overnight, in negative temps. I was able to drive it home, in limp mode. Come to find out, it is the valve body on the transmission. That in cold temps the valve body can fail. After some research I found that it is a KNOWN issue with these vehicles and there has even been a “Urgent-Distribute Immediately” Service Update regarding the problem. Urging dealerships to review the VIN’s they have in their possession for the issue. I had the vehicle towed to a shop, where they confirmed the problem was the transmission valve body. They were unable to perform the work as it takes a qualified technician to replace. So it got towed to the closest GMC dealership. They have had it for two weeks now. They confirmed that it is a known issue and there have been no recalls. But they did tell me I was “in luck” because they stock that item so we won’t have to wait for a part. Not only is it going to cost me $3500 to replace something that is a know issue with this vehicle, but it could have ended in tragedy if no one would have come along when we were stranded. I urge you to make this a recall on these vehicles.
