2022 Chevrolet Suburban

The Office of Defects Investigation (ODI) has received 36 Vehicle Owner Questionnaires (VOQs) alleging engine failure in vehicles subject to Recall 25V274. In each VOQ, the engine had the recall remedy completed prior to the reported failure incident. Recall 25V-274 addresses vehicles equipped with a L87 6.2L V8 gas engine that experienced engine damage or failure. Recall 25V-274’s remedy includes an engine inspection.  Based on the results of the inspection the vehicle will receive an oil change to a higher viscosity oil or an engine replacement.  The complaints received allege failures of both remedies. ODI is opening this Recall Query (RQ) to assess the adequacy of the remedy for Recall 25V-274. 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. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

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 own a 2022 Chevrolet Suburban with approximately 115,000 miles. While driving, the check engine light illuminated and the vehicle suddenly entered limp mode. The transmission lost normal operation, including reverse gear, significantly limiting the vehicle’s ability to operate. The failure occurred without warning and created a potential safety concern because the vehicle could no longer respond normally to driving conditions. The vehicle was inspected by a Chevrolet dealership, where technicians diagnosed a failed transmission control valve body and confirmed the valve body required replacement. I paid to have the repair completed. After the repair, I learned that GM issued Special Coverage N242454441 for certain 2021-2022 Chevrolet Suburban vehicles equipped with the same transmission. The bulletin describes premature transmission control valve wear that can cause a service engine light, reduced engine performance, harsh shifting, and requires replacement of the transmission control valve body. My vehicle experienced the same failure and required the same repair, but my VIN was not included in the covered population. I contacted GM before authorizing the repair and requested assistance, but my request was denied because my VIN was not included in the special coverage. I am submitting this complaint because my vehicle experienced the same transmission valve body failure identified by GM despite not being included. I request that NHTSA document this failure and determine whether additional vehicles equipped with the same transmission should be included in any current or future safety investigation.

While driving down the high way with the check engine light on, a message appeared on the screen and said “unable to shift soon. Service transmission immediately.” After driving a few more miles the vehicle shifted to neutral, and then as soon as I got on the shoulder of the highway and slowed to approximately 5 mph, the vehicles wheels locked up and the car jerked aggressively into park. This exact issue has occurred multiple times while driving. It is unsafe to drive the vehicle.
