ENGINE
My 2024 GMC Yukon XL Denali Ultimate (VIN 1GKS2KKLXRR331476, 6.2L L87) has been consuming engine oil excessively since early ownership. At the 20,219-mile oil change it was already a quart low, and it has needed repeated oil additions between changes since then. The vehicle is now at about 32,400 miles. I reported the problem in writing to the selling dealer on April 30, 2026, and again on October 9, 2026. GM opened case 115829578, but no oil consumption test or repair has been done. Low oil in this engine risks bearing damage and sudden engine failure while driving, the failure mode NHTSA is investigating under EA26005 for L87 engines built after Recall 25V-274's production window, which includes this vehicle.

POWER TRAIN, ENGINE, STEERING
2024 GMC Yukon XL Denali with approximately 30,000 miles. The vehicle previously completed the L87 recall remedy (NHTSA 25V274000). The dealer inspected the engine, it passed, and the higher-viscosity oil change, filter, oil-fill cap, and owner’s manual insert were performed. Despite that remedy, the vehicle later experienced a sudden loss of propulsion on the highway while traveling with family. The vehicle began shaking and the engine shut down. There were no check-engine lights, warning messages, or other notifications prior to or during the failure. The vehicle was towed to a GM dealer. Diagnostic testing at the dealer confirmed that the engine requires replacement under Special Coverage N252494003. The dealer indicated the replacement engine will be remanufactured. The service department also confirmed that the vehicle had been maintained in excellent condition and that all recommended services were completed as required, so the repair is being covered by GM at no cost to the owner. The prior recall remedy did not prevent a subsequent sudden highway failure with no advance warning. Once the current repair is completed, the vehicle will carry a permanent engine-related entry on its history report at low mileage, which will affect residual value. This complaint is being submitted to document the post-remedy failure involving sudden loss of propulsion on the highway with no warning.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
On September 17, 2026, at approximately 22,861 miles, the 6.2L L87 V8 engine in my 2024 GMC Yukon XL suffered a sudden loss of propulsion and was subsequently confirmed by an authorized GMC dealer to be seized and require complete replacement. I was entering northbound I-75 from the Mt. Paran Road entrance in Atlanta, GA with two of my children in the vehicle. This entrance has an extended acceleration ramp where vehicles accelerate to interstate merging speed. While accelerating, the engine briefly stuttered and then the vehicle stopped producing power when I pressed the accelerator. I was unable to continue accelerating and moved onto the limited shoulder. Other vehicles continued accelerating toward I-75 and passed immediately adjacent to us at significant speed. My children and I remained stranded there for approximately two hours waiting for a tow. The vehicle was towed to an authorized GMC dealer, which confirmed the engine is seized and requires complete replacement. The vehicle and failed engine are currently at the dealer and available for inspection. This vehicle was previously subject to NHTSA Recall 25V-274 / GM N252494000 for L87 engine failure and loss of propulsion. An authorized GMC dealer completed the recall procedure on November 3, 2025. The engine was not replaced; it passed the prescribed inspection and received the higher-viscosity-oil remedy. Despite completion of the recall procedure, the engine subsequently experienced the loss-of-propulsion condition identified by the recall. I understand NHTSA has investigated L87 engine failures occurring after completion of this recall remedy, including RQ26001 and EA26005. I am reporting this post-remedy failure because it may be relevant to that investigation.

ENGINE
Update to original claim filed 11760897. Dealership inspected on 9/9/2026 and found engine damage severe enough to warrant a complete replacement. Catastrophic damage. Unspecified what caused the damage, but service advisor made me aware of a deep gash along the cylinder wall after removing the cylinder heads, unspecified cylinder. Likely from cylinder 3 where the code was being displayed- P0303. Vehicle was in the beginning stages of an oil consumption test and had a history of oil loss without any visible leaks. Add oil light came on 650 miles after oil change. Oil was likely being burnt up through combustion due to damaged cylinder wall. Unknown time for new engine to be installed. Estimated backlog 600 engines, could be regionally or nationally. Replacing engine at 29,800 miles, however vehicle has been having these issues much longer- closer to 20,000 miles. I want consumers to be aware this vehicle was not part of the national recall. Vehicle was manufactured in July 2024, two months past the recall date established for these GM engines.

ENGINE
2024 Yukon XL 6.2L V8 following a complete engine failure at 37,446 miles and the significant safety incident that resulted. On XXX, while traveling from [XXX] to [XXX] on [XXX], the vehicle suddenly lost acceleration while traveling at 65mph on a 2 lane HWY, displayed a Low Oil Pressure warning, developed loud knocking and ticking noises, and became inoperable. We were forced to drift to a stop in an isolated desert location after passing a highway sign stating “Next Gas Station 94 Miles.” Our family of four remained stranded for approximately 5½ hours in temperatures exceeding 100°F. During that time, we spent more than three hours working with OnStar, but no workable transportation or towing solution was provided. Ultimately, my mother drove approximately five hours from [XXX] to retrieve our family, and we arranged and paid for commercial towing ourselves. As the hours passed, our focus shifted from transportation to protecting our children from prolonged exposure to extreme heat. This concern was heightened because our youngest son has an underlying medical condition that affects his ability to regulate body temperature and has a single functioning kidney, increasing concerns about dehydration. Following delivery to Michael Hohl GMC in [XXX], the dealership documented the following findings: “Metal in oil.” “Metal bypassed oil filter.” “Need to replace engine.” We appreciate the professionalism of the dealership throughout this process. Our request is not directed at the dealer; it reflects our belief that replacing the engine does not adequately address the circumstances surrounding this failure or restore confidence in the vehicle.

FUEL/PROPULSION SYSTEM, ENGINE
On August 20, 2026, while driving my 2024 GMC Yukon XL Denali equipped with the 6.2L V8 engine at approximately 70 mph on the interstate, the vehicle experienced a sudden and complete loss of motive power without adequate warning. The vehicle unexpectedly shifted into neutral and would no longer accelerate or maintain highway speed. This occurred in active interstate traffic and almost resulted in a serious accident as I attempted to maneuver the vehicle out of the flow of traffic. The engine would not restart, and the vehicle had to be towed to a GMC dealership. The GMC dealership subsequently diagnosed that the engine had locked up and determined that the engine requires complete replacement. This failure created an immediate and significant safety hazard for me, my family, and surrounding motorists. My vehicle is affected by the 6.2L engine recall, and I am extremely concerned about the safety and reliability of the proposed replacement engine. I have become aware of reports from other owners alleging failures involving replacement engines as well, including similar sudden losses of propulsion. I am concerned that replacing the engine may not adequately address the underlying safety risk if replacement engines are experiencing similar failures. I am requesting that NHTSA investigate not only the original engine failure, but also whether replacement engines used as a remedy are adequately correcting the defect. A sudden engine lockup and complete loss of propulsion at interstate speeds presents a serious risk of collision, injury, or death.

My vehicle "passed" the engine recall only to have the engine blow at 33,000 miles. My vehicle was at the dealership for 52 days most of the time was spent waiting for the new engine. Dealership was amazing, GMC however is the worst. My new engine has about 1,000 miles on it and it stutters occasionally when the auto start turns on.

ENGINE AND ENGINE COOLING
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.
