2024 GMC Yukon Xl Powertrain (other) Problems

1.XXX XX— GM Recall Notification (Recall No. N252494000) I received official notification from General Motors of Recall N252494000 affecting my vehicle. I brought the vehicle to [XXX] as directed to have the recall remedy performed. 2. XXX — First Report of Engine Propulsion Issues I reported engine propulsion concerns to Jim Ellis. This was my first formal complaint regarding the performance of the vehicle following the recall remedy. 3. XXX — Oil Type Change Performed by Jim Ellis Jim Ellis performed an engine oil type change, switching to 0W-40 oil, and advised me that this change would serve as the fix for Recall N252494000. I accepted this remedy in good faith. 4. XXX — Low Oil Warning Light Activated Approximately nine months after the recall remedy, and well before the end of the recommended oil life cycle, the low oil warning light activated on my dashboard. This is abnormal and indicative of excessive oil consumption. I returned to Jim Ellis, who performed a fresh oil change and placed my vehicle on a 6,000-mile oil consumption test — an acknowledgment that an oil consumption problem exists. 5. XXX — Active Engine Misfires, Jerking, and Flashing Check Engine Light While operating my vehicle on Sunday, May 31, 2026, I experienced severe engine jerking and misfires. The check engine light began flashing — not steady — which I understand to indicate an active and serious engine misfire event. I was genuinely concerned for my personal safety and immediately parked the vehicle. It has not been driven since. 6. XXX — GM Corporate Case Opened I contacted GM Customer Care and was assigned Corporate Case Number INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am filing this complaint regarding a serious and ongoing safety issue with my GMC Yukon Denali that began with a complete engine failure while driving on the highway with my entire family in the vehicle. While driving at highway speed (about 60–70 mph), the vehicle suddenly lost power and shifted into neutral on its own. While still moving, I tried multiple times to shift back into Drive so I could safely get off the road, but it would not engage. I was only able to coast partially onto the shoulder before the vehicle came to a complete stop, still partly exposed to traffic. The engine shut off and would not restart at all. It would not go into Drive or Neutral, and the vehicle was completely dead. And it had to be towed. The dealer later told me the engine had failed and that a new engine was installed. About a week later, I picked the vehicle up. Less than 20 minutes after leaving the dealership and getting back on the highway, smoke started coming from the vehicle and warnings appeared, messages that the engine was overheating and that I needed to stop the engine immediately. The vehicle was not drivable again and had to be towed back. I again had to arrange transportation home. A few days later, I picked the vehicle up again. Since then, I have had serious four-wheel-drive and drivetrain issues. The vehicle became stuck in 4 Low and I could not get it out for over a day. When it finally came out, the drive mode buttons stopped working correctly. Selecting 2 High sometimes puts it into 4 High, selecting Auto puts it into 2 High, and Auto mode no longer appears. Even when it shows 4 High, the steering is restricted cannot steer 100% to the right or left and the vehicle binds, pops, and jumps when turning. I believe this vehicle is unsafe and poses a serious risk.

Transmission appears to be lunging and shuttering. Dealer has indicated that the valve body need to be replaced or the vehicle could leave me stranded or without propulsion while driving. From my research this appears to be related to other safety recall and service campaigns for this type of vehicle and the transmission that I have in my vehicle. Also the camera system doesn't work correctly as it relates to parking assist and collision control. My repair dealership has stated they are having trouble getting GM to cover this repair.

Good morning. It’s about the safety recall for loss of propulsion due to manufacturing defects that can lead to engine damage and engine failure. GM notified me about this in September 2025 . So, I drove my vehicle to the dealership to inspect my vehicle , my SUV passed the examination, they replaced the oil recommending now another one with higher viscosity, new oil cap and an owner’s manual insert free of charge. Ladies and gentlemen; My concern from here on now is, just doing this is going to give me a peace of mind? Meaning the manufacturer defects issue is not longer in my vehicle? I paid a top dollar for this specific unit because I like to travel across the country even to go to Mexico. Right now I’m driving the truck silent, no music at all.driving the vehicle just to go to the store, to buy groceries,very short trips, around my neighborhood Trying to hear any noise, any knocking noise on my engine, observing the dashboard controls constantly, my family and I decided to stop traveling due to my vehicle is not secure to do it with this particular 6.2 engine because my notification letter from GM says that if the vehicle fails during operation will lose control increasing the risk of crash. As a GM customer, using my vehicle with my family I don’t feel safe and comfortable with my vehicle therefore I am asking and expecting for a better solution from General Motors. Not just replacing the oil for another one with a higher viscosity because doing this only is telling me that it’s just a cheap remedy, but the manufacturer defects are still there with my vehicle . I know they extended the warranty to cover this defect if something happens in the future, but isn’t about that , is about the safety, the concerns, the feelings of the family members involved in this insecure situation while driving this vehicle in the highway at 70 miles an hour.Ladies and gentlemen. I am pretty sure you can help us with this petition , GM should be able to do something way better.

I am filing this complaint regarding GM Recall N252494000 (NHTSA Campaign Number 25V274) for my 2024 GMC Yukon XL (VIN: [XXX] ). The issue involves a serious engine defect related to the crankshaft and/or connecting rods, which can result in catastrophic engine failure and loss of propulsion while driving—a clear and dangerous safety risk. I first became concerned when early reports of this issue began circulating publicly. As a father of young children, I became increasingly uneasy that my vehicle could potentially fail while in operation. Receiving GM’s formal recall letter only validated my growing concern for my family’s well-being. It’s deeply frustrating and unsettling. The notice states that parts to repair or replace the engine are not currently available, and offers no clear timeframe for when a remedy will be provided. I feel like we are being strung along while forced to continue using a vehicle that may become unsafe at any moment. This delay is unacceptable. There has been no offer of a loaner vehicle, no proactive communication from the dealer, and no assurance from GM that they are prioritizing driver safety over logistics. I am requesting that NHTSA investigate whether GM is doing enough to provide timely remedies to affected customers. I also urge you to consider whether interim solutions (such as alternative transportation or more aggressive recall execution) should be mandated. Thank you for your attention to this matter.

The car has made a high pitched metallic rattle on cold start ever since I received it. I have taken it into the dealership multiple times for this and have had the lifters in the engine replaced but they never addressed the other noise, which I have video evidence of. The car died at 24,740 miles on the odometer in the middle of a highway in the middle of nowhere. The vehicle started to feel like it was braking on acceleration, there were no warning lights. The vehicle just lost acceleration power and I had to coast to the shoulder. Luckily I had time to pull over without interference from other traffic. Once on the side of the road I tried to crank the car again and a very loud metallic sound happened that sounded like I threw a wrench in a fan. The car lost electrical power very shortly after. I called onstar for help and she asked if I could shift the car into neutral which I could not. They had problems finding anyone that wasn’t hours out that could come tow my car and suggested that I try to find an alternate method of transportation since a wrecker service probably wouldn’t transport my entire family. Uber was not around to get me, Lyft was not around to get me and there was no taxi service. I had to rely on the local fire department to rescue us as it was hours with myself, my two children and my dog on the side of the road in 90F heat. Once at the dealership they confirmed it was indeed a catastrophic engine failure and I am currently waiting months for a back ordered engine with a rental I’m paying partially out of pocket for, in a car that’s entirely way too small for my family with no ETA on the engine in sight. I know multiple people personally who this has also happened to, same exact scenario and same exact engine just different model years.
