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.

ODI will close this RQ and continue to investigate complaints of post-remedy engine failure for Recall 25V-274 as part of an Engineering Analysis (EA26005).

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).

part number 13554821 fuel pump control module has failed 2 times. April 2023 on Interstate 95 near Savannah GA in very busy traffic. Vehicle buckled and seized, just barely made it to the shoulder of the road. Same part failed again 9/18/26 while turning onto Sunrise Hwy in NY another very dangerous situation as we were stranded in the middle of a very busy intersection

While driving the vehicle on a roadtrip in Missouri, the engine lost power and had a flashing check engine light. Upon diagnosis by three different technicians, the 6.2L Engine needs replaced after only 123000 miles. The lifters and camshaft have failed. This is a known safety issue and numerous recalls have been implemented, but my high end Denali is mysteriously absent from the recall. This is unsafe and unsatisfactory.

Incident

Sep 19, 2026

Vehicle has been consuming engine oil at a rate of approximately 1 quart per 500 miles. On XXX, owner added 1 quart of oil in [XXX], then drove a round trip to [XXX] and back (approx. 860 miles). On XXX at 55,329 miles — only 9 days and roughly 860 miles after that quart was added — an oil change was performed at an independent shop; the technician noted no oil was present on the dipstick prior to service. On XXX at 55,829 miles — exactly 500 miles later — the vehicle was taken to an authorized GMC dealership, and the dipstick again showed no oil prior to service. The dealer began the manufacturer's oil consumption test protocol, performing an oil and filter change and other maintenance. Within approximately 74 miles of this service (current mileage 55,903), the engine began making an audible knocking noise. Oil level was checked and confirmed full/normal, ruling out low oil as the cause. The knock has been intermittent — not present at cold idle start, but returning during driving conditions, raising concern about potential engine failure or loss of power while driving. They can not get it back in till XXX. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Incident

The rod bearing failed while traveling at highway speeds, so yes our safety as well as others traveling on the interstate. It is available for inspection. A dealership inspected and confirmed the reported problem. The manufacturer is aware of the persistent problems with these vehicles' engine components, reliability and safety. There were not any symptoms, warning lights, etc. prior to failure. I had just purchased the vehicle and it was inspected by two independent mechanics prior to failure. I have contacted the manufacture to find that my VIN was not covered under the recall. The recall covers vehicles manufactured starting 3/1/2021, my vehicle was manufactured 10/2020. THE RECALL SHOULD BE EXPANDED TO COVER ALL OF THESE VEHICLES.
