Luckily, truck was sitting in idle waiting on my wife and daughter to leave the store so we could go home. Engine began to run rough, and then died. Would not restart. Had this happened just a few moments later while in traffic, it could have been catastrophic for our family. GM dealership said the engine was nearly locked up and needed a new long block and several other ancillary parts. So far, we have no internal pictures and nothing was harmed externally.

I live in Illinois, my 2019 GMC Sierra 1500 SLT has 51,318 miles on it as of 12/31/2025. What component or system failed or malfunctioned, and is it available for inspection upon request? Engine Oil Cooler hose line detaching from crimp - small oil leak currently. Not yet fixed. Available for inspection. How was your safety or the safety of others put at risk? If this component fails, all oil from the vehicle will be lost and inoperable. This could cause a traffic accident, especially if towing a load. Has the problem been reproduced or confirmed by a dealer or independent service center? Confirmed by an independent service center. I will be taking my vehicle to the local GMC service center for additional confirmations. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, but GM has acknowledged the issue through these customer satisfaction surveys (CSP XXX/ XXX). Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There has been no failure yet. A small oil leak was found on my garage floor. My issue is that this is a known issue in cold weather climates.

Friday night coming home. While entering my driveway. The check engine light came on. The engine sounded really bad. Rough idling. Saturday morning. Took it to a mechanic shop. While on my way to the shop, the truck had loss of power. The first mechanic shop told me that the truck was having engine failure. Was not sure at the time but the L 87 is known for having lifters and bearing failure. Monday the truck was taken to the dealership Novak motors. For extended warranty, repair or possible engine replacement. It has been two weeks. Have not heard anything yet. But the timing of the incident was good. Because the engine failed when I was pulling in to my driveway.

On November 25th, 2025 I had my wife, kids and baby grandson in my truck driving approx 50 mph when the trailer brake light appeared on my dash. I thought that was strange since I was not pulling a trailer. Shortly after my truck felt like it was going to stall and complete loss of power. I pulled into a turn lane and coasted into a gas station parking lot. I put the truck into park and turned the motor off and then restarted it. The truck was running extremely poor and sounded like it had rocks loose in the motor. I had it towed into an automotive repair facility I have always used and they told me my engine was gone and had to be replaced. I had been told by an oil change company a few weeks before that this engine was under a recall. I checked into it but this model year was not included. I did further research and founded out that this model year was under review. Something needs to be done as I was lucky this was not a busy highway or this could have ended worse.

Status: open (inferred from source dates) · Engine; Engine And Engine Cooling:engine:hard Parts Internal/mechanical
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.

PE25001 · Loss Of Motive Power Due To Engine Failure
Opened Jan 16, 2025 · Closed Oct 23, 2025
Status: closed (inferred from source dates) · Engine; Engine And Engine Cooling:engine:hard Parts Internal/mechanical
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.
