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).

I drive a 2023 Chevrolet Silverado 1500 3.0L Diesel with the 10-speed transmission. The transmission control software failed to monitor/detect valve body wear or trigger a 5th-gear 'limp mode' safety net, resulting in three separate instances of sudden rear-wheel lockup at speed. The dealer was unable to replicate the issue during a service visit from 6/10 - XXX. The issue was raised as the transmission was shifting increasingly badly leading up to this service visit. The first full lockup occurred a few days after receipt of the vehicle on XXX driving eastbound on [XXX]. Off the gas, coasting downhill. Once everybody started speeding up, I increased the throttle gently and the truck shook violently. I initially thought I had been hit by another vehicle but realized it was the transmission. Speed was noted 24 mph. The second incident occurred XXX while traveling to [XXX]. Driving southbound between [XXX] and [XXX] at approximately 50 MPH in a coasting condition. Went to pass a slow vehicle and the vehicle jerked violently an locked the rear wheels. Initial assumption was that I had been hit. Was able to regain control and continue. The third incident occurredXXX while traveling from [XXX] to [XXX]. Driving eastbound on [XXX] at approximately 35 mph, when moving from a coast to acceleration posture, the vehicle again locked the rear wheels and jerked violently. Finally, onXXX when traveling southbound from [XXX] to [XXX], I stopped for fuel. When attempting to accelerate onto the freeway, the vehicle failed to engage 6 gear, stumbled, and then went into limp mode with a check engine light. On XXX a [XXX] dealer found code P0747 and addressed the issue with [XXX]. I was forced to rent a car to continue my journey to [XXX]. GM ultimately shipped my truck back to me one week later. The software 'fix' clearly did not work as intended and remains a serious safety hazard. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Evaporative emissions purge pump failed at 18,473 miles. As the bumper-to-bumper warranty has expired GM refused to cover this repair. As this is a known problem with certain GM vehicles, the repair is covered for older model year out-of-warranty cars and for residents of other states (California, for example). This repair is covered by the emissions warranty in some states (California), but not Michigan.

While driving at Interstate speeds, the engine abruptly stalled, causing an immediate loss of motive power. I was able to coast off the Interstate to a surface street then into a gas station parking lot. Once stopped, the engine would not start again. It would crank repeatedly but never fire, like it was out of gas, but I had nearly 1/2 tank still. This is a safety concern having a 3yr old truck just die on you at highway speeds. This vehicle matches the exact year, make, and model of the expanded GM Emission Recall Campaign N262558690-01 (NHTSA ID 11037321) for Fuel Pump Power Control Module failures, but the VIN is currently excluded."

This truck and hundreds, if not thousands of others has many issues with the electronic shifter. Not only do they frequently fail, but Chevrolet does not have any parts available to the dealerships for weeks. These Duramax 3.0 diesel engines are also a huge problem with the emission system and DEF. They constantly fail and we are spending thousands to repair. My truck is stuck at a dealership in [XXX]. I had to rent a vehicle to drive back home to [XXX]. The dealer has no idea how long it will take to get a shifter from Chevy. Is there any help available. Why aren't these shifters under a major recall? I am literally stranded after paying $65,000 for a truck! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving my 2023 silverado 1500 down the highway when my engine started loosing power and then shut completely down at 65 mph. My safety and others were at risk due to speed and loss of power. I was lucky enough to not be on an interstate or in a metropolitan area. This happened due to a recall on this particular motor from General Motors (6.2 Liter). My vehicle was taken to a local General Motors dealership and the engine replaced. There were no warnings or abnormal behaviors of the vehicle prior to and the vehicle was taken in for the recall prior to the incident. The motor oil was changed to the recommended 0-W40 by the dealership.
