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.

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).

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.

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.

This problem isn’t just the 6.2L engine. My 22 Suburban has the 5.3L and had engine failure on the freeway going 70 mph in April 2026. Loud noises and loss of power. Towed to dealership and was confirmed that it was the same issues as the 6.2L. The dealership only replaced certain components (gears, rods, camshaft etc.) Parts replaced and vehicle returned a month later but still loss of power and bad idle. New dealership in May 2026, replaced same parts, said faulty parts were used at previous dealership. Vehicle repaired and returned in June2026, a day later new code for service transmission now code thrown and parking break not working. Returned to dealership and said it was a fuel pump module? failed. No vehicle for 3 months and lots of headaches. This recall needs to be extended to the 5.3L engine as well. Needs full replacement, not just repaired. My vehicle still doesn’t run great but Chevy will not honor anymore repairs.

I am submitting a safety complaint regarding our 2022 Chevrolet Suburban equipped with the 6.2L L87 engine. The vehicle is subject to GM Product Safety Recall N252494000 / NHTSA Recall 25V-274. Our Suburban underwent GM's required recall inspection, including the Picoscope inspection. The engine passed the inspection and the engine oil type was changed in accordance with GM's recall procedure. Since passing that recall inspection, we have experienced the following issues: On XXX, at approximately 40,527 miles, while we were in [XXX], the vehicle displayed a reduced-acceleration warning and check-engine light and experienced significant acceleration problems and loss of reverse. We took the vehicle to Essenlohr Motors, a Chevrolet dealer in [XXX]. The dealer diagnosed a P0700 condition/control solenoid stuck off and repaired the transmission valve body under GM warranty. I understand this incident was diagnosed as a transmission issue, and I am including it as part of the vehicle's recent history rather than asserting that it was caused by the L87 engine defect. The dealer's repair order documents both the check-engine condition and our report of the reduced-acceleration warning. On XXX, after we had returned home to [XXX] from our trip to [XXX], the Suburban had 41,798 miles on it. We drove approximately 2 miles from home when a “Low Engine Oil–Add Oil” warning appeared. We immediately returned home and parked the vehicle. After allowing it to sit for approximately 15 minutes, we checked the engine oil and there was no oil registering on the dipstick. We saw no evidence of an external oil leak on the garage floor or underneath the vehicle. Rather than continuing to drive it, we had the Suburban towed to Wiers Chevrolet in [XXX]. The dealer confirmed that the engine was approx. two quarts low on oil and indicated that there was no apparent leaks. They performed an oil change and started a 6,000 mile oil consumption test.

The contact owns a 2022 Chevrolet Suburban. The contact stated that while driving at highway speeds, the vehicle shut off while displaying "Service Transmission Now Unable to Shift Soon" and "Engine Power is Reduced" warning messages. The vehicle was towed to a dealer where it was previously inspected under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, no repairs were performed. After remaining at the dealer for nearly eight weeks, the engine was replaced under warranty. A few weeks after the replacement, the same warning messages were displayed on the instrument panel upon startup. The contact attempted to drive the vehicle; however, the vehicle failed to exceed 20 MPH and was towed back to the dealer. While attempting to drive the vehicle into the service bay, the technician experienced severe hesitation and engine stalling. During diagnostic testing, a large amount of metal shavings was discovered in the oil filter, and the vehicle was diagnosed with the same engine failure as before. The vehicle was repaired; however, the contact refused to take possession of the vehicle due to safety concerns. The manufacturer was notified of the failure, and a case was filed. The failure mileage was 61,000.

Just for information purposes, I have been an ASE certified Master automotive technician for 30 years. As I was accelerating onto the highway, my transmission downshifted hard, throwing everything forward. It then went into limp mode with “ses” light on. I was able to drive it home stuck in one gear. The next morning I tried to drive the truck. It had reverse but when trying to go forward, the transmission was stuck in between gears and fighting itself. I manually shifted into low gear and it seemed to clear up the binding. I drove the truck up and down my driveway which is about a half mile long. No more “ses” light but when I went to park it, there was no movement in reverse. As I researched the problem I found the recall information on the valve body. I called several dealerships to find a service writer that had experience with these transmission issues. The truck was towed to a dealership that knew about this recall. Their technician checked for codes but there were none. It seems these trucks reset or “lose” codes when the ignition is turned off. He checked the fluid and decided that the reverse clutch must be burned up. They quoted a transmission replacement at $6500. I asked if they had driven the truck forward at all to reset any trouble codes. The truck was “unsafe” to drive due to the random harsh downshift and erratic behavior. I went there(putting myself in danger) to drive the truck to reset any trouble codes. Within a mile the truck did the same thing. It stored a code P2732. I was informed that GM would not do anything for me unless there was a P747. After reasoning with the service manager and also GM, it was obvious I was out of luck. I had the truck towed home and removed the transmission pan. The fluid was clean and there was no debris. The problem is in the defective valve body from GM but since it didn’t have the code P0747 I’m stuck having to repair it myself. The truck has 126k miles still well within the extended service range.
