FUEL/PROPULSION SYSTEM, ENGINE, ELECTRICAL SYSTEM
I was driving on interstate and thank God I got off the exit and vehicle suddenly cut off. An indicator came on stating to push start to restart vehicle while the vehicle shifted to Neutral on its own. Then a Low oil pressure sign came up on dashboard. I tried push start again and nothing happened. Lucky by this time I was just off the exit so I was able to come to a stop and shift to Park. I tried push start again and the dashboard just went dark and started making a clicking noise. After some time around 1 min I tried again and it did crank up and I was able to try and get as close the the edge as possible but still in a two lane road on the bridge of an off ramp. I say thank God because 30 seconds sooner I was going around 60mph with my 4 month old in the backseat. Lucky I got to the exit when this happened. From the research I have done apparently this happens a lot to this model I have 2024 GMC Yukon Denali XL. I had a recall for this issues supposedly fixed back in October 2025. Things could of been much worse. Also this all happen coming from just having an oil change done at the dealer. Literally leaving the dealership going home. The dealership loaned me a vehicle they say for 3 days for free after that I may have to pay because it may not be covered by GM which is ridiculous. The vehicle is at the dealer and I will be waiting to hear there analysis.

POWER TRAIN
I was traveling along i80 and suddenly the vehicle shutdown. I put the transmission in Neutral and coasted to a stop. Once stopped, I check It would not start or even turnover at that point. I still had all electrical services and such. The vehicle. I was stranded on i80. Then had to be towed to the nearest GM Dealer in Evanston Wyoming. Heritage Chevrolet GMC. It was left there for diagnosis where their technician, several days later diagnosed it with a bad engine. There was no warning or check engine light that appeared. I even have a picture from a little while earlier while driving earlier that morning. It took it because I was surprised it was getting 28mpg in v8 mode. but I am glad I had that photo to show no diagnostic lights were on.

ENGINE
Knocking noise from engine-no check engine light initially. Next time it was started knocking was still present and the check engine light was on. Contacted Champion Chevrolet in LaGrange KY. Dealership diagnosed problem (Code P0308 - Cylinder 8 misfire). Compression test on Cylinder 8 failed. Removed valve cover and confirmed loud tick in the rocker shaft and worn camshaft lobes. Was told I would need a new engine and that repairing the existing engine was not cost effective. So, $22,722.14 later, i have a new engine in my 2020 GMC Yukon and have the original engine (core charge) in my shop in case it is needed for evaluation to help determine if the GM recall should be expanded to 2020 model year (and others not covered by the current recall).

ENGINE
We have a 2018 Yukon with a 6.2. It has 70,000 miles on it. We have taken very good care of it and changed the mobil oil less than 5,000 mile intervals. The engine is making a terrible knocking noise. We stopped driving it the minute it started. We put it on a trailer and pulled it home and it has not been started since then. We had no warning lamps or messages to alert us of an issue. We have not had it to a dealership yet to have it inspected as we are pretty sure it is the same issue that other 6.2 engine vehicles are having. This vehicle has been well maintained. We are hoping that this year/make/model will be included in the recall for a new engine as that is what ours will be needing. It is very disheartening that you spend that much money on a brand-new vehicle, and it does not have very many miles on it and the engine fails.

ENGINE, POWER TRAIN, SUSPENSION
12/16/25 (evening): Warnings began cycling across the screen: 1) Service ESC, 2) Vehicle Leveling for Stability, 3) Rear Axel System Off, 4) Engine symbol began flashing, and 5) Service Traction Control. I felt vibration/bouncing while driving as well. 12/17/25 9 AM: Took 2021 GMC Yukon Denali to GMC dealership. They ran a computer scan and reported a misfire, but nothing else appeared to be wrong. They told me that sometimes a low battery can cause the warning lights and messages to cycle. They recommended that I keep driving it and return if the warnings appeared again. 12/17/25 9:18 AM: I left the dealership. I drove 4.5 miles, and all the same warning lights came back on. When I pulled into a parking lot, it smelled like my engine was on fire, and dark smoke was coming from my rear exhaust pipe. I called a flatbed tow truck and had the car returned to the dealership. Mileage: 52,285 GMC 2021Yukon Denali XL 6.2L V8 engine Well-maintained with regular oil changes. The dealership told me there was a lifter failure and that the engine could be damaged and would need to be replaced if the cam, pushrods, etc., were damaged. They also told me I was out of warranty by less than 60 days. The dealership said my warranty expired in October 2025, even though my vehicle is a 2021 with only 52,285 miles. They just informed me that the left lifter was replaced at 6,000 miles and that they will replace the right lifter. I am concerned about further damage down the road, given the recalls on the GMC 6.2L engines.

ENGINE AND ENGINE COOLING
The contact owns a 2022 GMC Yukon XL. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate, and the engine stalled. No warning lights were illuminated. The contact stated that the failure occurred while driving on a busy highway, and the contact's wife and four minor children were also occupants of the vehicle. The contact stated that the incident was significantly scary. The vehicle was driven to the shoulder of the road, which the contact considered unsafe for him and his family. The contact stated that both the contact and his family, which included a one-year-old child, had to walk to a safe location and sat for more than 40 minutes. The vehicle was towed to the dealer, where it was diagnosed that the engine had failed and needed to be replaced. The vehicle was not repaired. The dealer informed the contact that the repair was covered under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling), but the repair could take two months, and the parts needed to be ordered. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 72,020.

POWER TRAIN
I am writing to formally file a complaint regarding a serious and ongoing issue with my vehicle that has placed my safety at risk and resulted in significant inconvenience and financial burden due to General Motors’ failure to honor my warranty in a timely manner. While driving on the highway, my vehicle suddenly began losing power and displayed flashing warning messages indicating that it would not shift into gear or out of gear and that power could be lost. This created an extremely dangerous driving situation and posed a serious safety risk to me and other motorists. I brought the vehicle in for warranty service, but General Motors was unable to honor the warranty repair in a timely manner. As a result, I was without my vehicle for several months while it sat undrivable on the dealership lot. Once the vehicle was finally repaired and returned to me, the exact same transmission-related incident occurred again. Once again, I was left without the vehicle for an additional period of days. This repeat failure has severely shaken my confidence in the reliability and safety of the vehicle. When I picked up the vehicle after the subsequent repair, I was informed by a General Motors technician that the brakes and rotors were most likely pitted and damaged and would need repair or replacement because the vehicle had been sitting undrivable for such an extended period of time. I was explicitly told this damage was expected due to the prolonged inactivity caused by the unresolved warranty issue. It is critical to stress that the vehicle only sat undrivable for such a long period of time as a direct result of General Motors’ inability to honor the warranty in a timely manner. Despite this, I am now being told that the brake and rotor damage is considered a “maintenance issue,” even though a General Motors technician directly advised me that this damage would occur as a consequence of the vehicle sitting for months due to warranty delay

ENGINE, FUEL/PROPULSION SYSTEM
I purchased this vehicle in May of 2025. It currently has 9840 miles on it. While driving in October the vehicle shut down and locked up. After getting it towed to a dealer I was told the diesel motor and the fuel system were blow and seized and need to be replace. The vehicle is still currently in North Carolina while I live in Virginia. Supposedly parts are in for repair for 3 weeks now and I still don't have my vehicle nor any info on when I will get back. Davenport GMC of Rocky Mount and GM have been rather useless in this process. I cant believe I am going through this with a $90,000 car that was four months old.

ENGINE, FUEL/PROPULSION SYSTEM, STEERING
While driving on a two lane road, my vehicle put itself into Neutral without me doing anything and the engine stopped. All things powered down. The engine stopped. not propulsion, nothing. I tried to pull over to edge of road. Car would not start - no activity. The vehicle had to be towed to the dealership. My safety was put at risk by my car simply stopping while driving down the road. The dealership has confirmed the engine needs to be replaced. There was no warning of engine problems or ANY indicators.

ELECTRICAL SYSTEM
The Infotainment screen which controls the A/C, heating, defrost, cameras and all other info for the vehicle does not come on in th vehicle. This began happening after owning the vehicle for 3 days. After taking to the dealer, Delray GMC, we were informed by the service personnel on our second trip in for the recurring problem that General Motors knows this is a problem and are selling the vehicles with this factory engineering design defect and currently there is no repair. Living in Florida this is a problem in the extreme heat with no A/C, being from Illinois, when we return this will be a serious problem, Not knowing if we will or will not have access to heat, cannot control the temperature or the defrost on the vehicle and having a infotainment center that is non functional. We consider this a hazard to our safety and feel that GM is fraudulently selling consumers defective vehicles knowing this may be a safety hazard.

ENGINE
On December 1, 2025 at around 5pm CST, my 2021 GMC Yukon XL started making a squeeling noise then stopped while driving down the road. It left me stranded in the middle of the road. A P0016 CODE was produced and the engine light came on. I had the vehicle towed the next day to Stew Hanses GMC in Clive, Iowa. The engine was torn down for inspection and was told the rod bearing went bad and it had low oil even though I was within the window since the last oil change and having documented all necessary required maintenance. I was told the engine needs to be replaced and am in the process currently of Stew Hanson GMC replacing all necessary parts. I was told I do not have a recall on the vehicles vin number by GMC corporate and the GMC dealer. It is coming up on a month since the incident happened and vehicle towed to dealership. I do not have pictures from the dealer yet or final invoice as this is still in process. I wanted to document this somewhere.

AIR BAGS, POWER TRAIN, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
In these vehicles between two thousand and five and two thousand and seven are constantly, such as my vehicle, low oil pressure and lower rod bearing failure constant is which what I have and due to wiring cruise control becomes no good because of computer failure. I cannot afford to fix the lower rod bearings and notice that you have already a recall for trucks, twenty twenty one and up.But this problem has been ongoing from gm since twenty twenty five or more. I also took my vehicle in for an airbag recall.And after that, I still have an airbag light on after they fix the airbag recall.0
