Engine has seized twice, completely shutting down without electrical power or brakes. The vehicle also shut down in an intersection (no power, brakes, flashers). I was able to pull to the side on the 2 engine seizures but not during the electrical shutdown at the intersection in the turn lane. The engine was replaced the first time by Quality GMC in Albuquerque, NM. The 2nd engine is being replaced by Diamond GMC in Palmdale, CA. Warning lamps on the 1st engine seizure was tire pressure warning. The electrical shutdown was forward collision warning, emergency braking, etc. The 2nd engine seizure said something about engine needed to be restarted.

Was going up a hill and all of the sudden the engine stopped, the truck coasted to the edge of the road. A message came on saying 'Press start to reset engine.' Doing so did nothing. The truck ended up having to be towed to a dealer. They were not able to turn the engine over by hand and ended up diagnosing the engine as a seized from a failed bearing. They ended up replacing the entire engine with a new identical one. They have not been able to tell me if the new engine is in the same engine group that I could experience the same thing a second time.

While towing my boat to the Florida Keys, I encountered a series of mechanical issues on Interstate 75. The engine’s exhaust became excessively loud, causing the engine to abruptly shut off. Despite successfully maneuvering into the safety lane, I was unable to restart the engine. I promptly contacted the dealership, which dispatched a tow truck to my location. However, the tow truck driver was unable to put the vehicle in neutral gear. Subsequently, I reached out to GMC, which informed me that the tow truck required a flatbed for transportation. I waited another two hours for a flatbed truck to tow the vehicle to the dealership. A few days later, I received notification that my engine had seized, necessitating an engine replacement. The dealership informed me that the 6.2-liter engine was experiencing a national backorder. I had purchased this used vehicle less than a month prior and had not yet made my initial payment. Consequently, I find myself without a vehicle. The dealership has been unable to provide an accurate timeline for the repair to be completed.

My wife and I were traveling westbound on [XXX] just outside of Durkee Oregon, when while going up a hill with Cruse set to 72, the truck began to slow down drastically. When I looked down I was then going 60 and showing down fast. I was able to get to the side of the road and then the truck stopped, it shut off. At that point the truck has not be back on. It would not turn on and Onstar reported that there is an issue with the Engine and transmission. No warning lights came on until we stopped. Then the Engine light was on and the truck said that it was overheating but the oil temps were normal. I feel lucky that there was not much traffic. My wife and I were on the side of the road for 2 hours at dusk and in the dark with 65+ MPH traffic zooming by. Also had a impossible time tracking down a rental call just to continue to my wife's grandmother's funeral service. I just talked with the dealer and they will not have a diagnoses for me until late tomorrow. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.
