2024 GMC Yukon Xl

On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001.  This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete engine replacement. Additionally, ODI has received 191 reports of L87 engine failures in engines produced after the production period cited in Recall 25V-274. GM reported receiving 6,953 complaints of post-remedy engine failure. ODI is opening this Engineering Analysisto continue investigating complaints of post-remedy engine failure. ODI is expanding the scope of this Investigation to include engines produced after the production period cited in the recall. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001).  GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274.  This presents a potential safety risk that warrants further investigation.  ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024.  GM cited the root cause as a supplier manufacturing and quality issues. GM’s  recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007).

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.

Sep 17, 2026

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.

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.

Incident

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.
