2022 GMC Sierra 1500

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). To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

Current Unsafe Conditions: Post-Replacement Active Safety Failures. The vehicle presently exhibits two distinct categories of active, ongoing, and dangerous safety failures, both of which were introduced as a direct result of the engine replacement performed by Monument Chevrolet: (a) Severe Drivability Failure. Between approximately 1,500 and 5,000 RPM, the engine repeatedly and without warning lunges forward, drops all power, and lunges again — cycling in this manner between three (3) and six (6) times before stabilizing. This behavior occurs across all gears and driving conditions, which creates a severe and unpredictable hazard particularly when merging into traffic or accelerating onto highways. This failure constitutes an immediate and ongoing risk to the safety of myself and other motorists. (b) Complete ADAS System Failure. The frontal crash response warning light is permanently illuminated on the instrument cluster, rendering the following federally relevant safety systems entirely non-functional: (i) Automatic Emergency Braking / Forward Collision Alert; (ii) Cruise Control; and (iii) Lane Change Assist / Lane Control System. All of these systems were fully operational and properly functioning before the vehicle was submitted for the engine swap. Their failure is an assembly defect introduced by Monument Chevrolet during the course of the repair and constitutes a warranty and safety defect for which General Motors, as the manufacturer and warrantor, bears full responsibility. Medical Hardship and Urgency. This vehicle is my sole personal transportation. It is essential for travel to active medical appointments and upcoming medical procedures. The ongoing failure of General Motors and its authorized service network to restore this vehicle to a safe and fully operable condition has created a serious hardship that directly affects my ability to access needed medical care. Yes, it was driven by a service department supervisor. He did experience the issues.

For the past 6 months I’ve had issues with my crash avoidance system, steer assist and lane departure warning. The crash indicator light would illuminate on my dash for no apparent reason. That would disable my crash warning system, steer assist and lane departure warning but, I could still adjust my distance for my brake warning indicator. The other problems that are not safety related is cruise control and automatic high beam lights will not function. I researched the Internet and found this is not an uncommon problem for this year model. The most common fix (if the windshield is not dirty) was remove the F 11 fuse, in the fuse panel beside passenger door for 10 seconds, that would allow the system to reboot. That worked for 3 months with more than 10 occurrences of the light illuminating on the dash. Now the crash indicator light is on continuously and will not reset by removing the fuse. The computer is up-to-date and all the settings in the infotainment system for the crash avoidance system are activated. Check numerous Internet websites, the cameras for this system is on backorder. So there must be a parent problem with the system. I was required to purchase 36 months of OnStar, I did not purchase a renewal agreement after the 36 month and this issue started soon after.

Top Grill/Hood trim piece - it is separate from the main Grill. It detached and flew off at interstate speed. Thank God it missed several cars behind me. The passenger side corner came loose and before I could safely make my way off the interstate the piece ripped all the way across and flew over the top of the truck. May have gone 30 feet in the air prior to landing on the asphalt between the two lanes.

My truck was serviced for the front chrome grill separation recall last year. On Saturday, 8/1/2026 while driving at highway speed the grill deflector separated from the vehicle violently. I was able to pull off of the highway and remove the part as only the passenger corner clip (with screw) was partially retaining the deflector. Upon looking at the "repair" or recall, the corrective action does not appear to have been done correctly per N242490120. The chrome coating was not scuffed let alone removed from the part and an insufficient amount of epoxy was used to attach this deflector. Damage was done to the hood and lower grill during this incident. I have had numerous and considerable issues with the purchasing/servicing dealership where I bought this truck.

My truck is intermittently having the camera display a warning code. While in reverse or while towing and trying to use the surrounding cameras. It happens randomly and almost caused accidents in parking lots. While towing I use it for lane changes and with non towing mirrors it’s a very dangerous issue that could cause an accident especially on the highway

While driving my 2022 GMC Sierra 1500 (VIN: [XXX]) in active traffic, the 10-speed automatic transmission suffered a sudden and catastrophic internal failure. Without warning, the vehicle stalled in the middle of traffic and forced itself into a hazardous "limp mode," severely restricting my speed and acceleration. This created an immediate, high-risk safety emergency, leaving my passengers and me vulnerable to a rear-end collision before we could navigate out of the live roadway. The vehicle was towed to an independent facility (Kenny's Transmission, Repair Order #XXX) at 65,579 miles. Diagnostic troubleshooting confirmed a "Number 6 Solenoid Code" and "Internal Transmission Mechanical Failure" (3-4 races away, total loss of reverse gear), requiring a complete replacement of the transmission assembly utilizing an official GM service part at a personal cost of $6,673.10. General Motors has previously acknowledged 10-speed transmission control valve defects and wheel-lockup hazards by issuing safety recalls for diesel variants, but gas-powered models like my 6.2L L87 engine are experiencing identical, highly dangerous sudden losses of motive power without federal recall protection. I am requesting that the NHTSA investigate this systemic failure rate on 2022 gas models before it causes a major collision.
