1) [XXX] - Was driving on the interstate at 65 - 70 mph when the truck suddenly shut off and shifted to neutral. I was in the far left lane and had to coast thru 2 lanes of high speed traffic to the right shoulder before the truck stopped coasting. Once I coasted to a stop on the right shoulder of the interstate, I tried to crank the truck up a couple of times and it finally cranked and I proceeded on to my destination. When I reached my destination and was attempting to park, the truck shut off again and would not crank after that. I then called roadside assistance to send a wrecker and take it to my local GMC dealer in Montgomery, Alabama. 2) My safety and others was put at risk when the truck, without warning, shut off and lost power while driving at 65-70 mph in heavy interstate traffic causing the truck to suddenly decrease speed and having to maneuver through traffic , without power, while coasting to the side of the road. 3) [XXX] - The service department at Mullinax GMC in Montgomery, Alabama called me about a week later to say the engine had "LOCKED UP" and that they had contacted GMC to begin the process of getting it fixed. They indicated that this was not uncommon with this model truck, and that it happens sometimes. 4) There were absolutely no warning lamps, messages, sounds or any other symptoms of the problem prior to the engine failure. I was caught completely off guard when the engine shut off. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I started my truck on [XXX] and after driving less than 3 miles the check engine light came on and then light for traction control needs service came on. I stopped and notice engine was idling weird. So I called dealer and they recommended I bring in. I proceeded to drive but could not drive over 40 mph as the engine would not idle past that and started hearing clicking noises. I slowly get the vehicle into service at McKinney GMC Buick in McKinney, TX. Two days later I get a call stating that engine needs to be replaced due to bearing failure and excessive metal in oil and oil filter. Which damaged the engine and is not repairable. The service center informed that this is common with my 6.2 L V8 and there are four other trucks same issues. The engine is on back order and don't know when I will be able to get my vehicle back. This appears to be a known issue for GMC and they are not telling people who could be in danger on road at any moment without warning.

The trucks engine completely shut down while going approximately 60 MPH while merging onto the highway. The trucks dash flashed multiple times, a ticking noise was heard, it put itself in neutral, and shut the engine off. All power was lost. I did still have brakes. Safety was a concern as there was a vehicle behind me entering the highway too. Cars to my left as well passing at highway speeds. Once I got the vehicle stopped on the shoulder of the highway it put itself in park. It would not restart. The vehicle was towed to a local GMC dealer. There were no warning lights of any kind that came on. No indication that there was a problem. A couple days later I was informed that the truck would need an entire new engine upon inspection. I was also told by the dealer that the truck had no oil at all in it. The engine consumed it internally by their evaluation.

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.
