My TAILGATE kept opening randomly and ENGINE WAS MAKING CLUNKING SOUND initially. Lost many tools on the highway once when it opened. Dealership told me my truck is not covered under a recall for both issues, even though other similar vehicles are. I refused to pay anything to have it fixed. They claimed my truck “wasn’t built in the factory that has recalls”. A month later the STARTER AND BATTERY burned up when I started up the truck, something locked up it sounded like. Eventually it started but didn’t sound right. A few days later the engine finally blew up. I paid out of pocket for everything for that trip. It’s currently back at the dealer being repaired with a new engine for the recall but GMC refuses to pay for the initial clunking/starter/battery and the tailgate issues. I’ve encored so many charges with tows and rentals from all these issues. I would like full reimbursement for everything.

The windshield defroster and heater blower speed reduces and/or shuts off shortly after accelerating to highway range speeds. Blowing snow from Alaska roads will melt and refreeze on the windshield reducing visibility creating a safety hazard. The truck has not been successfully repaired after multiple and lengthy attempts. The heated steering wheel also malfunctions intermittently. The blower motor does seem to come back up to speed when vehicle speed is reduced to city speeds but is intermittent also.

1.)When driving the vehicle it will randomly shutoff while driving with loss of brakes and steering until it will randomly turn back on.The vehicle experiences intermittent electronic and drivability malfunctions. The issue appears to involve one or more vehicle control modules and/or electronic systems. At times, warning lights and system messages appear, and vehicle performance is affected. The vehicle is available for inspection upon request. 2.)These failures create a serious safety risk because they occur without warning while driving. The vehicle may lose normal functionality, display multiple warnings, or behave unpredictably. If this occurs in traffic, at speed, or while maneuvering, it could increase the risk of a crash or leave the vehicle stranded in an unsafe location. Furthermore on 3 separate circumstances I came close to crashing the vehicle putting at risk lives in the vehicle and outside. 3.)The problem is intermittent and has been difficult to reproduce on demand. I have taken the truck to the dealership multiple times. The dealership has stated that because the issue is not actively occurring when they have the vehicle, they have been unable to duplicate the concern and have instructed me to continue driving it until the issue happens again. Despite this, the problem continues to return during normal use. 4.)The vehicle has been inspected by the authorized dealership on multiple occasions. To my knowledge, it has not been inspected directly by the manufacturer, police, or insurance representatives. 5.)Intermittent warning lights and system messages appear, including at times a check engine light and other alerts. These warnings may appear suddenly as the truck shuts off and then disappear after the vehicle is turned off and restarted. Another thing to point out is that the audio and turn signal chime cut off randomly. The issue first began while the vehicle was already in normal use and has continued to reoccur since.

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.

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.

Engine
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).
