Defect investigations
Loss of motive power due to engine failure
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) 2019â2024 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, the federal safety agency 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.

What 2019 GMC Sierra 1500 owners say
Most recent owner complaints, unedited.
I was driving my 2019 GMC Sierra Denali with a 6.2 L engine down the highway suddenly heard loud noises coming from the engine pulled over and called for a tow truck to take the truck to the dealership for inspection. The dealership told me the engine was blown and that I would need to get a new replacement engine. I believe this engine has had multiple complaints and recalls I don't believe at 137,000 miles and it was serviced at the dealer regularly should fail.
Catastrophic Engine Failure/Engine Seized at Highway Speed We were driving on a two lane highway at approximately 55 mph. We had just left home and only gone 20 miles. All of a sudden pressing the gas pedal did nothing and after a few seconds the truck died. I was able to move over a foot or two but there was really not much shoulder. We were blocking traffic. I tried to call for help but had no service and making an emergency call would not work either. I had just started to walk down the highway until I got service when a sheriff's deputy pulled up behind us to help. Thankfully no one was hurt. There were no warning lights or sounds on my dash. The only thing the truck said was to shift to Neutral to restart which of course wouldn't work. The only other indication of what had happened was the temperature gauge was as hot as it would get. When we popped the hood the coolant was boiling and spewing out of the relief valve and the oil was completely empty. My oil was full before we left. My engine had siezed. The dealership won't tear down the engine to find the specific cause becasue it's too costly. It is still sitting at rhe dealership now.

Recall N262576260 has just come out. My truck has the same symptoms/conditions consistent with the recall. I have a code P0420, check engine light, high oil consumption and loss of power. also, the GM representative i spoke with told me i have an open recall N242450631. it does not show on the federal safety agency website and it does not show at the dealer. the high oil consumption has allowed the turbo to damage the catalytic converter and something in the engine to tap due to less lubrication.
I was driving my truck (2019 GMC Sierra 5.3L) while pulling a travel trailer to go camping. As I was getting onto the interstate, without any prior warning, all at once the truck began to shake, make a concerning noise, and various warning lights began displaying on the driver information panel. I pulled the truck off as safely as possible and had the truck towed to a GM Dealer for service. After investigating the engine, the service department informed me that an exhaust lifter failed, camshaft lobe was damaged, and a cylinder wall was scored resulting in the engine having to be replaced. As this happened while on the interstate with many other passenger vehicles and semis around us, and with the added component of pulling a travel trailer in the moment, my family and myself were in danger of oncoming high speed traffic while getting the hindered truck off of the road, sitting waiting for a tow truck to come, having to unhook the trailer on the side of the interstate and re-hook it up to another truck, and transferring my wife, kids, and myself to another vehicle.
The contact owns a 2019 GMC Sierra 1500. The contact stated that while driving at 65 MPH, the vehicle experienced a slight loss of motive power, an abnormal sound emitted from the engine, and all warning lights illuminated. The contact pulled over to restart the vehicle; however, the vehicle failed to restart. The vehicle was towed to the contact's residence and was later towed to the dealer, where it was diagnosed, and the contact was informed that the engine failed and needed replacement. The manufacturer was notified of the failure. The failure mileage was 139,802.
Engine died while on the freeway. Had the truck sent to my dealer via flatbed with AAA. They diagnosed it as the known lifter issue—lifter broke and metal went into the camshaft and scored it. So I need to replace the camshaft and lifters. They’re quoting me $12k for that. I have 83000 miles on this car and I take very good care of it.
Vehicle started running very rough & displaying error codes for "steering assist is reduced", "service parking brake", and "service ESC". While driving vehicle it would accelerate & deccelrate on its own. Limped the truck to our local reputable mechanic who ran tests & determined it as an issue with the lifters. It is known gm is currently having issues with the 6.2l v8 engines. Clearly this issue is wider spread than the current few years they are admitting to. We are having to have a new engine installed at our expense.
The engine started making a loud knocking noise and lost power. Luckily the event happened in a neighborhood and no one got hurt. The check engine has been on for brief periods prior to this event.
