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).

My 2023 Chevrolet Silverado 1500 equipped with the 6.2L V8 engine experienced a sudden loss of propulsion while driving. The engine did not completely shut off, but pressing the accelerator produced no power or acceleration. I was on the highway going about 80mph with traffic when it happened and left me stranded on the side of the very busy highway. The vehicle was taken to a Chevrolet dealership on September 18, 2026. Following an engine teardown, the dealership informed me that an engine bearing had failed. As of November 5, 2026, the vehicle remains at the dealership while GM determines whether to rebuild or replace the engine. The engine recall had reportedly been completed before I purchased the vehicle. I am concerned about the safety of this failure and whether the recall remedy adequately addresses the underlying defect.

I was traveling from [XXX] to [XXX] work. Was traveling in the left lane on the [XXX] traveling at approx. 75mph at 8PM when I suddenly lost all power to my vehicle. Everything was running fine; there were no warning signs, no sounds, no dash indicators, no nothing. Just suddenly lost all power to the vehicle. It was terrifying but I was somehow able to navigate to the breakdown lane without crashing, mostly due to all the vehicles around me slamming on their brakes, skidding, and swerving out of the way. The state police showed up and called for a tow. my vehicle was dragged across the pavement with the wheels and transmission locked, and up onto the flatbed. My vehicle was taken to a near-by Chevy dealer where it was "bounced" off the flatbed and onto the lot. The truck was later diagnosed with a failed engine. The dealership wouldn't supply a courtesy vehicle, nor assist with a rental. I was able to figure everything out and travel back home. was notified on XXX that my vehicle was ready. Traveled back to [XXX] and picked up my truck. My truck was pristine before this happened. When I got the truck back it was obvious the left out in the elements with the hood removed as the entire engine bay was covered in what looked like silt. It's definitely not the same truck as before this happened. Ran different, runs different, brakes are different. After a few weeks, my dash started intermittently flickering off. It gradually got worse and a week later it just completely died. Soon after, I traded in the truck for a new vehicle. Took an absolute beating on the trade-in value due to all these issues.

"While reversing slowly toward a fuel pump at a gas station in a 2023 Chevrolet Silverado 1500 Trailboss LT, the vehicle's Reverse Automatic Reverse autonomous braking system erroneously engaged with maximum hydraulic force. The truck came to an instantaneous, violent stop without driver input or any physical obstacle present besides a gas pump off to my left and a car filling up way behind me. The deceleration forces slammed the occupants and caused a severe, immediate lower back and shoulder injury to the passenger/driver due to the extreme change in kinetic inertia. This appears to match GM TSB 24-NA-048 regarding faulty sensor calibration creating virtual bumper errors near reflective surfaces. I have not taken it to the dealer because of this since it just happened. I didn't report it to the police or insurance. The car just beeped at me while it slammed the brakes. I didn't see what it saw on the camera. It has not done this to me before.
