On XXX, while traveling at 75 mph on a major interstate highway, this 2024 GMC Sierra Crew Cab suffered a sudden and catastrophic internal engine seizure, resulting in an immediate and total loss of propulsion. This defect put the safety of all occupants and surrounding motorists at extreme risk, forcing the driver to navigate a completely unpowered, rapidly decelerating vehicle through high-speed traffic to reach the shoulder without the aid of engine power. There were absolutely no warning lamps, error messages, or mechanical symptoms prior to the failure; the engine locked up instantaneously without any advance warning. Following the incident, the vehicle was flatbed-towed to an authorized franchise dealership (Dossett GMC in [XXX]), where it remains un-repaired and is currently available for inspection by the manufacturer or federal investigators upon request. Critically, this vehicle was previously presented to a certified General Motors dealership at 34,766 miles for inspection and service compliance under Federal Safety Recall N252494001 (which covers engine component failure and subsequent loss of propulsion). The vehicle was cleared as passing the manufacturer's inspection protocol at that time. The total engine failure and seizure occurred less than 9,000 miles later at approximately 43,634 miles. The catastrophic field failure of this vehicle demonstrates that the manufacturer's current safety recall inspection and remedy are insufficient to identify or mitigate the defect, presenting an ongoing and severe risk to public highway safety.

Engine seized at 23,291 miles, approximately 3,661 miles after GM's authorized dealer performed a PicoScope inspection under Recall N252494000 and certified the engine as passing. July 2025 recall attempt was documented as incomplete with no remedy available. November 2025 inspection passed the engine. Engine seized March 2026. New engine installed under Special Coverage N252494003. New drivability concern — hesitation and lurch at low speeds — appeared immediately after the repair.
My truck has completely shut down/ loss power on several occasions. Happened when I was l slowing down or completely stopped. Everything goes dark. Had to wait several minutes before truck would start.
Engine failure after passing PICO test. Engine completely locked up on a busy highway without the ability to even put it in neutral. Yes, confirmed by dealer that there were metal shavings in the fluid. Inspected by authorized dealer. No lights came on in the vehicle prior to the engine failure.
Engine failure at 12,000 miles

Traveling Northbound in the left lane on [XXX] approximately 1 mile prior to the [XXX] exit. I increased my speed to move to the right lane and exit. After moving the the right lane and signaling to exit the highway a notification appeared on the gauge cluster stating to shift to neutral and restart the engine. After coming to a complete stop at the stop light I attempted to restart and nothing happened. I contacted OnStar for roadside assistance to get my truck and trailer towed and was informed they do not cover towing of the trailer. I accepted the tow of the truck and contacted the towing company who charged me $300 to tow my trailer 15 miles home. This happened late morning on Saturday and by Monday evening I was informed my engine seized and GM will be covering a replacement under warranty. My truck is less than two years old with 23K miles. The 6.2L engine was inspected a couple months earlier for the engine recall and was deemed ok. Clearly the inspection process is not very robust. I was told I could be without my truck for 1wk, 2wks, a month, but they are not sure since I’m 4th in line for a new engine and the truck first in line has already been there a month. I was also told GM is showing inventory in Michigan but the engines are not shipping. I’m currently waiting on a loaner vehicle but was told I cannot tow with the loaner vehicle which throws a wrench in my plans.

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.

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.
