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).

Driving my vehicle on the interstate at 70mph when the transmission made a hard downshift and brought my wife, two children, an infant and toddler, and I to a very sudden 40mph.Before I was able to find a shoulder to pull over the transmission fluid overheated and vehicle would no longer change gears. I then towed it to the dealership where purchased originally. Vehicle was then towed to and diagnosed at a Chevrolet dealership where ultimately resulted in a valve body and clutch failure.

The dealership diagnosed the truck after investigating a ticking noise and engine misfire. During the inspection, they removed the valve cover and found that one of the pushrods on cylinder #5 was bent. Further disassembly revealed that both lifters on cylinder #5 had failed, causing excessive wear on the camshaft lobe. As a result, the dealership determined that the necessary repair was to replace the camshaft and all 16 lifters. The engine was then cleaned, reassembled, and tested to ensure proper operation. The root cause of the issue appears to have been a failing lifter, which led to damage of the associated valvetrain components.

Incident

The contact owns a 2022 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, the forward collision, check engine, and traction control warning lights illuminated, and the messages "Forward Collision Unavailable," "Service Traction Control," and "Service ESC" displayed on the instrument panel. An abnormal muffler sound was heard, the engine compartment vibrated, and the vehicle failed to accelerate above 35 MPH. The vehicle was taken to the dealer, where the engine was disassembled and it was determined that the lifters failed and the engine required replacement. Prior to the failure, the vehicle was taken to the dealer for an illuminated check engine warning light and an engine knocking sound; however, the dealer only cleared the diagnostic trouble codes while the vehicle was under warranty. The manufacturer was notified of the failure by phone. The failure mileage was unknown.

Thursday XXX - Left [XXX] on our way to [XXX] for a beach vacation on our 2022 Chevy Tahoe z71. Made it to [XXX] and spent the night there Friday XXX - Left our hotel in [XXX] and headed to [XXX]. Expected arrival time 8 pm About 40 miles east of [XXX] our Tahoe shuts down and I pull to the side of the road in the middle of nowhere. It’s 99 degrees. I called several dealerships around and decided on Ryan Chevrolet in [XXX]. I called a tow truck and wait for 3 hours. My wife and two kids walk 1 mile to a gas station. I call the XXXstate patrol to get them to park behind me as semis at 80 miles per hour are flying by me. Having semis pass by at 80 miles per hour is obviously very scary and extremely dangerous. Tow truck takes me and the Tahoe to Ryan Chevrolet and am able to drop the car there 30 minutes before they close for the weekend. Tow truck driver takes me to the XXX airport where I have managed to rent an SUV that will allow me to complete my vacation. Drive through the night and make it to my hotel in [XXX] at 2:30 am. Thursday XXX - Drive back to [XXX] Friday XXX Go to Enterprise Rental cars in [XXX], explain that I will need a car till my Tahoe gets its engine replaced. I get a Chevy Blazer. Friday XXX - I drive 5 hours to [XXX] to pick up my Chevy Tahoe, return the Enterprise rental at the [XXX] airport and then drive another 5 hours back to [XXX]. I bought this car new at the dealership and has only been serviced by that same dealership. About a year ago the oil type was changed as part of the recall.

Beginning with 2026 model year production, the floor console/armrest lamp design was changed by removing the tilt-switch ball. As a result, the lamp remains illuminated when the floor console compartment lid is closed. The BCM turns the lamp off after the ignition is switched off to prevent battery rundown. This PI is to inform dealers of the change in the lamp and operation of the lamp following repairs.

This PI is to instruct dealer on diagnostic procedures that need to be completed prior to replacing a radio or IPC display

This Preliminary information communicates to dealers steps to follow to obtain an IOK radio.

This preliminary PI was created to advise techniians in the field that they will not be able to perform a GDS automated bleed with the scan tool dues to a issue with the software in the scan tool
