2024 GMC YUKON Complaints

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.

My vehicle failed the Picotest that GM is conducting on the engine. It is currently sitting at Romain GMC in Evansville Indiana. I am not sure if I was at risk but the dealership says it's unsafe to drive so my assumption is that my safety was at risk. The dealership states that it will take 3 months before a new engine is installed. There were no symptoms leading up to this recall inspection.

The contact owns a 2024 GMC Yukon XL. The contact stated that while driving at 70 MPH on the highway and attempting to accelerate around a possible drunk driver traveling on the roadway, the vehicle failed to respond as needed. The driver was able to pull over safely. There were no warning lights illuminated. The contact called 911 and called for Roadside Assistance, and the vehicle was towed to a local dealer, where it was diagnosed with an engine failure. The vehicle was not repaired. The vehicle was previously taken to the local dealer to be repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 32,000.

Driving down the inter state lost power and RPM raised, oil light came on and said to shut off. We checked the oil it was fine. Got back on the road then a knocking started and the vehicle shut off. I tried to start again and it wouldn’tand hour or so later it started and was knocking bad, I turned it back off. called tow truck driver to have it towed to the dealership.

I want to report the dealership, Hill GMC, in Newtown Square PA and the salesman, Vince Pace, that special ordered this vehicle for me in December of 2023 knowing full well that these cars had an engine problem. It was deceitful and cunning. I purchased a GMC 2024 Yukon Denali for $102,000 I am a senior citizen and I was taken full advantage of in this fraudulent sale.

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.

November 12, 2025 - Turned on car and immediately noticed multiple system failure notices and very slow ability to brake. Immediately took to dealership - said battery needed to be re-charged. December 9, 2025 - turned on car and once again immediately noticed multiple system failures and very slow ability to brake. Failures were "Brake System Failure, 43 MPH Top Speed, Forward Collision System Unavailable, Service Brake Pad Monitor, Service ESC, Service Traction Control, Service Sterring Column Lock" Immediately took to dealership. Over the last 25 days in service all the dealership has told me is that their master technicians have looked it over and do not know the root cause. They are waiting for a new technician from GM. They also have another Yukon at the dealership with the same safety symptoms. No issues with the car prior to these two instances of failures. Car should not be driven.

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.

vehicle parked for extended period, 7-10 days, entered vehicle on 12/05/25 and proceeded to start - immediately service transmission appeared in display, check engine light on, dash flashing and door locks going up and down and chiming of alarms. was able to place in reverse, backed up, put into drive and vehicle would move approx 5-8 ft, lock up and stop, start again and repeat, etc.. put vehicle in low1 was able to get back in driveway and parked. had vehicle towed to closest dealer who had a transmission specialist available and worked with GM warranty plus GM CarBravo warranty to address issues (multiple dealers refused or didn’t have available personnel and/or were multiple weeks out for repairs). called and advisor said i needed a new battery (22mo of a 36mo free battery replacement GM AC Delco) and to have transmission valve body replaced and no tcm, 3-5 days for part delivery and that this was under a GM Service bulletin # PIP6069 (which i pulled up online), stated this repair (valve body) fixed most vehicles but knew of a few instances where complete GM 10spd transmissions had to be replaced. glad this happened in my driveway versus while being on a long distance trip. waiting on part delivery and unable to use vehicle due safety issue with transmission.

Vehicle was operating on the interstate with cruise control activated. Time was approximately 9:15pm. Weather was fair with temperatures in the lower 60's. Speed was approximately 73mph. Without any audible or warning light notifications the engine stalled and all exterior lighting, power assisted braking and steering was lost. The emergency flashers were immediately activated to warn vehicles in nearby proximity of our emergency status. I tried to restart the engine(the transmission was showing to be in N)with no success. During the attempt to restart, the exterior lighting was restored. With the path of travel now visible, I was able to slow the vehicle to a safe speed and exit from the roadway onto the shoulder. Upon stopping, the vehicle was placed into P and OnStar was notified of the event. We remained in the vehicle until one of our friends was able to take us home. Onstar contacted AAA to remove the vehicle to the nearest GM dealership.
