2022 Chevrolet Suburban

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).

The contact owns a 2022 Chevrolet Suburban. The contact stated that while driving at an undisclosed speed, the engine failed after the message “Drive Carefully - Reduce Acceleration” was displayed and the vehicle then came to a sudden stop. The vehicle was unable to accelerate, and the engine seized. The contact replaced the battery, but the failure persisted. The vehicle was towed to an independent mechanic, and the vehicle was diagnosed with a blown engine. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline. The failure mileage was 125,000.

Incident

While towing a light trailer (~3,000 lbs) through the mountains on an interstate, my 2022 Suburban with the 6.2 engine suddenly got hot and shut off. There were no symptoms of the engine having any issues, it had been running well the whole trip. The temperature gauge went from normal to very hot in a very short time. I was not able to get it to a pull-off area and was stranded partially in the right lane of the interstate with several collision close calls. This problem was later determined by the dealer to be the common crank bearing issue for this model engine.

Incident

Jul 23, 2026

2022 Chevrolet Suburban, 3.0L Duramax diesel, 10-speed automatic, purchased March 2022, approx. 122,000 miles. In early August 2026 the transmission began shuddering at low speeds. Reported to the selling and servicing Chevrolet dealer on 08/11/2026 at 118,892 miles. No transmission diagnosis was performed; the dealer's written estimate recommended spark plugs on a diesel engine. The condition worsened. On 09/17/2026 the dealer verified the concern and documented a "very harsh shift which would continue until 5th gear" when accelerating, and found the transmission fluid "heavily contaminated with metal and clutch material." The dealer recommended transmission replacement at customer expense and stated GM Special Coverage N242454441 (transmission control valve wear, companion to Safety Recall 24V-797 / GM N242454440) does not apply because DTC P0747 is not set, although that bulletin lists harsh shifting as an effect of the worn control valve. The control valve body has not been inspected. GM's recall filing states this wear can cause harsh shifting and in rare cases momentary rear wheel lock-up. No warning lamps or messages appeared before the harsh shifting. No crash, fire or injury. The vehicle and transmission are at the dealer and available for inspection; a GM TAC/FSE inspection has been requested. Filing so NHTSA has a record of a 2022 Suburban diesel showing the recall symptom and being denied inspection on the basis of the P0747 code alone.
