2024 GMC Yukon Xl

First incident April 9 2024 not even a month after purchased. Vehicle dashboard lit up light a Christmas tree all warning lights while driving on highway. Vehicle shook and sputtered and turned off. The vehicle was serviced explanation given was loose spark plugs on a new vehicle. 2nd incident roughly month after recall repair for engine propulsion campaign. February 26 and 27 2026 . While driving the following lights came on Engine failure ,Brake failure , Service Transmission now unable to shift soon. I was terrified because I could not control the vehicle. I had the vehicle towed to the dealership. The answer to the issues was Battery failure. Third incident April 17th 2026 I driving on highway 70 miles check engine light comes on flashes dashboard goes dark. Vechicle sputters and shut down. I restarted the vehicle the warning on the display disappeared and the vehicle restarted. I reached returned the vehicle again to the dealership because the problem resumed slowing down even though I’m depressing the gas. Vehicle is shifting and dragging. Resulting unexpected lurching. My vehicle has been at the dealership since end of April 2026 it remains there currently. My representative stated a code indicating misfiring has appeared 18 times. Also everyday my vehicle keeps saying software update even I installed the update and it says complete. I know GM is not updating my vehicle software everyday. That indicates there is a computer issue as well. My anxiety level is through the roof at this point. I complained before about this same failures in a Cadillac Escalade prior to it lurching forward and crashing. I filed a complaint before February 2024 . There is something really wrong with GM engines and software. I know I’m not the only one experiencing these problems

This is a Post-Remedy Failure of Recall 25V-274 (GMC 6.2L L87 Engine). Following a full engine replacement performed by the dealer under this safety recall, the vehicle has suffered a catastrophic electrical compromise. The vehicle is currently throwing codes P2534 (Low Ignition Voltage) and U3018 (BCM Communication). Safety Hazards: The vehicle experiences sudden loss of power, engine stalling at highway speeds, and total failure of the exterior turn signals (hyper-flash). The AC system has been disabled by the Body Control Module due to low voltage, creating a hazard in high temperatures. This vehicle fits the exact profile of NHTSA Recall Query RQ26-001 and Engineering Analysis EA25-007. The manufacturer's remedy for the safety recall has failed to restore the vehicle to a safe operating condition, and the dealership is attempting to charge diagnostic fees to investigate their own defective recall workmanship.

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.

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.

I purchased my new GMC Yukon XL in October 2024. In February, with about 9,000 miles on it, I was approaching a highway intersection and beginning to brake. My vehicle put itself into Neutral, and then shut off -- while I was still moving. No dash lights came on, except for a message stating that I needed to press the brake and restart my vehicle. I took my vehicle into the dealership where I purchased it and they kept it for 8 days. They were unable to reproduce the issue and didn't do anything to mitigate the problem except for doing a "radio update" and adding lubricant to a window track. I was told I have to wait until it happens again and try to record it.

Two weeks ago, while driving on the highway, our Yukon suddenly quit accelerating and flipped into neutral. We had to quickly pull over to the left shoulder with our entire family. We put the vehicle into park and tried to restart, which it wouldn’t do. We ended up having to call OnStar and having it towed to the nearest dealer. They “repaired it,” yet a week later, the same thing happened while pulling up to a stop light. This time we were 4 hours from home and on a weekend. While waiting for a tow truck, the police towed it to an impound lot. Lots of money, time and red tape to get it out of the impound lot to the nearest dealer to have it looked at. It’s been there almost a week and all I’ve heard is that it’s most likely the motor but they still haven’t confirmed.
