ENGINE
I started noticing issues with my transmission around 55,000 miles on it. It first started with no noticing that it wouldn’t gear down when it needed to, and then when it finally did gear down, it would really jerk the vehicle. I started calling GMC then and questioning and putting in a claim. Just went back-and-forth four months. Now it was getting worse to where I could feel the transmission slipping it wouldn’t kick into upper gear or lower gear. Again, I was still calling GMC and reporting these issues. I was told to take it and have a transmission oil change, which I did costing me $300. I still noticed this problem and I continue to call. I kept being told that they would have somebody call me back which nobody ever called me back to find out specifics. I took it to a GMC garage have them put it on a machine, and I was told that it needed a new transmission and this wasn’t something GMC was covering. This new transmission cost me $6200 and was done on 1/5/25. Please remember this vehicle only had 64,000 miles on it, which is absolutely ridiculous to need a transmission at this mileage. I again had called in January 2025 reporting this and was told someone would call me back and never heard from them.

Driving the vehicle on the highway when I started to hear a ticking sound from the engine. After a few minutes, the check engine light came on and started flashing, traction control shut off and some system related to the rear end shut off. After inspection, it appears to have dropped a lifter.

ENGINE
My vehicle was apart of the GM L87 recall. I took it to the dealership and it passed the recall and received the remedy which was an oil change. Now about 3 months later, I was driving in the highway at approximately 70 mph when the vehicle lost power and shifted to neutral. I had to attempt to veer off the highway with no acceleration. Upon getting it to the side of the highway, it wouldn’t do anything at all and had to be towed. The dealership has deemed it needs a new engine due to the failure the L87s are facing. We had no warning at all prior to the engine failure, and assumed that after passing a recall it had some degree of safety.

ENGINE
I bought my truck on 10/29/25 on 12/04/25 haven’t even maid my first payment on the truck yet and my wife was on her way to work at 4 am when the engine shut off on its own and went in to neutral. She tried starting the truck again and it wouldn’t so she had to leave the truck abandoned in the middle of the road and walk to work in the cold and dark. We ended up getting the truck towed home a few hours later when there was a tow truck available. I work out of town so on 12/07/24 when I got back in town I started the truck up and everything seemed normal so I took it for a spin and right as I was getting on the highway it lost propulsion, engine shut off, and truck shifted on its own to neutral. I was almost rear ended by the truck behind me luckily I was able to get the truck out of the way in time. I had to sit and wait for 3 hours until a tow truck was able to tow the truck. This was on a Sunday so I could not get it dropped off at the dealership due to them being closed until the next day! Finally I got it towed to the dealer (all tow’s paid out of pocket as well)… 3 days later the dealer calls me back to let me know I’m getting a new engine not sure how long it will take, but they will get me a rental mean while and that’s all.

ENGINE, POWER TRAIN
The vehicle drove fine had no warning/ check engine lights. My girlfriend came up to a busy intersection and when she proceeded to cross the intersection the vehicles motor locked up stopping the vehicle in the middle of the intersection with traffic coming from both north and south direction. We had poor visibility due to blowing snow so she had to bail from the vehicle and stand on the side of the road so she would not be harmed if the vehicle was t boned. Vehicle stopped so hard and fast it threw her into the steering wheel. Was unable to get the vehicle restarted and could not get it to shift into neutral so vehicle blocked 1 lane of traffic completely and half of another lane until tow truck arrived to remove from road.

ENGINE, UNKNOWN OR OTHER, FORWARD COLLISION AVOIDANCE: WARNINGS
traction control system ESC system Suddenly and without warning, multiple warning lights started flashing including check engine. The vehicle lost power and traction. There was a loud knocking and metallic whining sound. The vehicle began to vibrate and struggled to move forward and felt like the wheels were slipping. The loss of these functions was alarming because it was dark, we were in a construction zone, and my 15-year old daughter was driving having recently earned her driver's permit. The car following us almost rear ended us. It was such an abrupt engine failure it scared me and my daughter.

Odometer Fraud. The contact purchased a 2004 GMC Yukon. The contact stated that while attempting to trade the vehicle in, the dealer discovered that there was a mileage discrepancy, per the Carfax report. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 165,563. The actual mileage could not be determined because the Carfax report displayed that the mileage had drastically fluctuated over the years. No other agency was contacted.

AIR BAGS, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Vehicle: 2021 GMC Denali Mileage: ~48,000 miles Purchase Price: $62,000 Issue: Airbags & crash sensors failed to deploy Complaint Text: I am filing a safety complaint regarding my 2021 GMC Denali. I was involved in a rear-end collision at approximately 45 mph, where I struck another vehicle straight on from behind. The impact was severe enough to total my vehicle, yet no airbags deployed, and no forward collision warning or crash sensor systems activated. This is especially concerning because this vehicle was previously involved in a front-end collision (not my fault) and underwent extensive repairs. I was assured all systems were repaired and functioning properly. Additionally, my vehicle had completed recall work related to safety systems prior to this crash. This is the second front-end crash involving this vehicle where airbags failed to deploy. Given the speed and severity of the impact, airbags should have deployed. The failure of these systems placed my life at serious risk. The vehicle has since been totaled and taken by insurance, but I am requesting that this failure be formally investigated as a potential safety defect in the airbag and sensor systems. I am extremely concerned that the vehicle’s safety systems were either defective or not properly restored following repairs and recalls.

ENGINE
In April 2022, I purchased a brand-new 2022 Yukon Denali from Roberts-Robinson Chevrolet GMC in Excelsior Springs, MO. Shortly thereafter, the first engine failure occurred in October 2022. The vehicle was towed to GMC AutoNation in Golden, CO, where it remained until repairs were completed in January 2023. Soon after the vehicle was returned, the second engine failure occurred in February 2023. The vehicle was again towed to GMC AutoNation, and repairs were not completed until April 2023. At that time, given the repeated failures, I worked with GMC and Roberts-Robinson Chevrolet GMC to replace the vehicle entirely. I took delivery of a new 2023 GMC Yukon Denali as a resolution. On October 8, 2025, the engine on the 2023 Yukon Denali also failed, marking the third major engine failure I have experienced across these vehicles. The vehicle was towed again to GMC AutoNation in Golden, CO, where it remained for two months. I picked up the "repaired" vehicle on Tuesday, December 9, 2025. This pattern of failures has caused significant disruption and distress. I have spent countless hours coordinating tows, securing rental vehicles, and seeking reimbursement for out-of-pocket expenses. More importantly, these repeated engine failures, all of which occurred while I was driving 65 MPH on I-70 through the Colorado mountains, have created extremely dangerous situations for me and my loved ones. Navigating heavy traffic during sudden engine failure and waiting on the roadside for assistance has been frightening and unacceptable for a vehicle of this caliber. Overall, this experience has been incredibly stressful and disappointing.

SERVICE BRAKES, STEERING, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Vehicle lost steering and brakes suddenly. Many errors on screen such as: Brake System Failure, ABS Failure, ESC Failure, Traction Control Failure, Maximum Vehicle Speed 43mph. Was able to slowly get home with no power assisted brakes. Did not drive it any more until it was taken to dealer 2 days later and the dealer could not replicate the errors. Dealer was able to see stored error codes; however, they could not verify any errors in any of the modules or computer. Dealer wants us to take it back and wife is scared to drive it due to no fixes or repairs. Loss of brakes and steering is NOT a situation to ask an owner to 'bring back when it happens again"

POWER TRAIN, STEERING
After noticing a "groaning/moaning" sound from the vehicle when turning sharp at low speeds the vehicle was brought into a dealership to be inspected. After inspection, the mechanic stated that the sound is coming from the rear differential and that it would need to be flushed/cleaned up to three times as a potential correction. If the clean/flush does not correct the issue, they would need to replace the entire rear differential. When asked what happens if the rear differential fails, we were advised that we could experience total failure and lock up. This is a safety issue in that if we are driving and the wheels lock up the potential for collision or major accidents is high. I also understand that the differential is meant to last the life of the vehicle and had 123k miles, the life of the vehicle is far from over. Another issue we are experiencing is excessive oil burning. The vehicle "add engine oil" light comes on after 2,500 miles when being regularly maintenanced. The vehicle should not require the addition of oil after that many miles, more so should not require oil at all unless you weren't properly maintaining the vehicle (which is not the case). I understand issues arise and things happen; I just want this to be acknowledged as a potential safety issue and corrected. Thank you,

At the time an oil change is needed, there is a warning light that says "low oil pressure and low oil." There also has been a "slipping" of the engine at around 60mph. GMC dealer states it is a torque converter. I am worried that the engine will fail or stall while driving The fuel pump control module has been replaced. Motor is not covered under the current motor recall and taking vehicle to transmission shop to have it checked as well
