2024 GMC Yukon Xl Engine Problems

The contact owns a 2024 GMC Yukon XL. The contact stated that upon taking the vehicle to the dealer to be repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling), the contact was informed that the vehicle passed the inspection and no repair was needed. However, the vehicle experienced engine failure approximately seven months later. While driving 50 MPH, the vehicle lost motive power. There was no warning light illuminated. The driver pulled over, restarted the vehicle, and resumed normal driving. The vehicle was taken to the dealer the following morning, where the Electronic Control Module was replaced under warranty; however, the failure recurred while driving 70 MPH three weeks later. No warning light was illuminated. The driver pulled over, restarted the vehicle, and resumed driving; however, the vehicle failed to exceed 40 MPH and shut off. The vehicle failed to restart and was towed to the dealer, where it was diagnosed and determined that the engine, radiator and seal kit needed to be replaced. The vehicle was not yet repaired. The contact was concerned that the recall remedy failed to prevent the failure. The manufacturer was notified of the failure and a buyback was requested, but the request was denied, and the contact was referred to the dealer for additional assistance. The failure mileage was approximately 27,800.

Driving on highway, engine stopped while driving 70+ mph. Had to get to the side of the multilane highway. Was towed to nearest GMC dealership. Dealer said the engine was locked up, and they have many vehicles right now with similar problems. They will have to replace the engine due to complete engine failure.

We're in the waiting period for our 3rd engine. 1st engine failure, while driving on interstate at 70+ MPH, engine stopped running, causing a very unsafe condition for family and surrounding vehicles. Engine failure 2 days later, towed to dealership for inspection, replacement engine was installed ~4 weeks later. 2nd engine failure, while driving on interstate at 75+ MPH, engine seemed underpowered and would rev upwards of 6000+RPMs, not exactly unsafe, but not usual operating conditions either. Returned to dealer, upon inspection, total engine replacement was recommended.

Driving on highway at 80 MPH and accelerator stopped working and car turned off. We had to coast off toll rd and hope for the best. No warning and happened with our whole family in the car. I had a recall notice from manufacturer but last time I tried contacting manufacturer/dealer they said no resolution was available to repair recall yet and that I couldn’t drop off my vehicle.

I perform all maintenance on my vehicles, I have previously been a ASE Certified Master Technician, so I know engines and vehicles very well. Vehicle is outside of current engine recall window due to the engine build date being July 15, 2024. Engine was over maintained, oil and oil filter changed 6 times in 17,732 miles, first oil and filter change performed at 544 miles, when 5W30 oil was put in engine, installed a magnetic drain plug and installed Filter Mags on oil filter. Ran 5W30 oil for 2 oil changes, then moved to 0W40 oil. Oil analysis performed for each oil change. Results were looking acceptable up until the next to last oil change at 13,801 miles. Changed engine oil and filter on 6/12/2026 @17,732 miles. Found a heavy build up of metal particles on the magnetic drain plug and when oil filter was cut open there was a heavy build up of metal particles where the Filter Mags were located and the filter element had fine metal particles in entire engine oil filter element. The engine has made no noise and is still running, but based on the evidence the engine is currently failing and if I would have continued to drive it, the engine would likely lock up on the highway. CLEARLY GM DID NOT solve the crankshaft problem July 1, 2024 and CLEARLY using a higher viscosity oil like 0W40 will not keep these engines from failing. If I would have continued to drive the vehicle and if I would have not changed oil and found metal in the oil, this engine would have absolutely failed on the highway. This vehicle has over 80% highway use.

2024 Engine failed while moving at 70mph out of state. De-accelerated rapid as I was changing lanes and was almost hit by two vehicles. Once of the interstate, I made it to the shoulder of an exit ramp that was a blind spot. Cars exiting to this ramp almost always had to veer to keep from hitting me. I purchased this vehicle in October 2024, never knew anything about a recall, was never disclosed to me about recalls. To this day, if I enter my VIN, there is no recall and I have never received any communication stating this vehicle was on recall. I complained to the dealer twice about unusual noise from vehicle, which they dismissed. I took it back to the dealer because my oil light indicated I was "low", this oil is too low, my concern was a leak. Took into GMC dealer, they stated we did not see any leak. Now this. Problem, GA law states in order to qualify for buyback, 24,000 miles or under 2 years. Well, I have 24,986...this automatically disqualifies me. SMH The options I was given are all a NO WIN for me! I was almost killed on the interstate, not to mention the level of stress and issues this car nightmare has caused me. $100k vehicle and I still owe 87K

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)

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

Purchase this Vehicle November 1st 2025 as a GM certified used vehicle. Had several issues with the camera system including the backup camera. Would go offline and not be usable for days. Vehicle went back to shop several times for this with no resolution. Now February 18th 2026 at approximately 630PM EST (after sunset) on the way into work traveling on the highway the engine lost power and engine shutdown. Vehicle shifted into neutral with the indication to press the start button in order to shift into Drive. This cause all of the lights to shutdown when it tried to start the engine. I was barely able to pull this over to the shoulder before I lost forward motion. Narrow shoulder. Tried to restart again with the same results. Call towing company. They attempted to jump start vehicle. Same results. All power shutdown. Truck was loaded onto flatbed and towed to dealership. Dealership states bad battery. Got authorization to replace battery from the dealer in which I purchased the truck. hey attempted to start and then it burned out the main fuse. They determined that the engine had seized and they were going to replace the engine. I looked up to find that GM had performed the engine oil replacement procedure in June of 2025. This vehicle is listed in the "recall" for defective L87 engines. Clearly changing the oil had no effect to remedy the issue. I have no faith that the new engine will not fail the same way this one did.

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.

****This complaint is an addendum to ODI Complaint #11715415 **** This report updates the prior complaint to reflect complete engine seizure and pending engine replacement following post-repair loss of propulsion. I respectfully request that NHTSA include my vehicle’s failure in its ongoing evaluations related to L87 engine failures, including Recall 25V-274, Engineering Analysis EA25007, and Recall Query RQ26001. My 2024 GMC Yukon XL Denali experienced progressive internal engine failure beginning at approximately 61, 975 miles. First attempt: The vehicle required camshaft and lifter replacement due to internal mechanical damage. Immediately after 4.5 week repair, the vehicle suffered sudden loss of motive power at highway speed.  The engine shut down without warning at 75 mph with children in the car. (Car was in owners possession for no more than 15 hours, and was driven 25 miles on the highway when it switched to neutral and shut down). Second attempt: The vehicle was towed back to the dealership. Additional electrical repairs were then attempted. (Fuse box) It shut down again during dealer testing. Third attempt: Subsequent internal inspection revealed cylinders 5 and 6 seized, requiring full engine replacement. This represents: • Repeated loss of motive power • Escalation from top-end failure to catastrophic lower-end seizure • Failure occurring immediately after dealer-performed repair(s) • A 2024 model-year vehicle with relatively low mileage Given NHTSA’s ongoing investigations into post-remedy failures (RQ26001) and out-of-scope bearing failures (EA25007), I request that this incident be evaluated as part of the broader defect pattern analysis.

Jan 8, 2026

About 4 weeks ago my vehicle began shaking uncontrollably while driving. The check engine light illuminated and multiple warnings appeared including emissions system, variable valve timing system, engine and transmission failures shown on the GMC app. I contacted the selling dealership and was given an appointment 4 days later. Later that day I drove less than 5 miles to pick up my children from school. During that drive the vehicle filled with a strong gasoline odor and exhaust fumes were overwhelming. I feared the vehicle could catch fire. I contacted the dealership again, stated the vehicle was unsafe, dropped it off at approximately 8:00 PM and was required to obtain my own rental vehicle. After one week I was told the engine required a camshaft and lifter replacement. Inspected & approved by extended warranty, parts were ordered and installed. I retrieved the vehicle on 23 days after the initial failure. The following morning (24th day) while driving approximately 75 mph on a major interstate with my children the vehicle suddenly shifted into neutral and would not re-engage. I was unable to shift into any gear and coasted to a narrow shoulder inches from traffic and guardrail.The dashboard stated the vehicle could not shift into gear and instructed me to push the start button. The engine would not restart. We were stranded approximately two hours in 10-degree weather on a major interstate with heavy semi-truck traffic. Roadside assistance was required. 3 days later the dealership stated the failure was a fuse block. After replacement the vehicle was test driven and stated to be operating normally. A second dealership employee test drove the vehicle, it died again and had to be towed back to the dealership. The battery was replaced after draining while disabled. Repeated mechanical and electrical failures resulted in complete loss of power at highway speeds and placed my children and me in immediate danger. I no longer believe this vehicle is safe to operate.

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.

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 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.
