Vehicle started making an odd noise and was immediately taken to the dealer. Engine light did come on after the noise started. Dealer confirmed that there was an issue with the camshaft/lifters and that they have had to perform this repairs to 8 other trucks with the same 6.2L engine. (Original repair bill is attached). Dealer performs the repairs, takes the truck for a test drive and within a few miles the engine completely seizes up stranding the truck in the middle of the road. They believe it was a separate issue that caused the engine to seize up and now after 12k of repairs I will also need to purchase a completely new engine. Currently waiting on the price and availability of a new engine but was told I may have to wait a long time since this is such a common issue there aren’t many available. Would be more than happy to share additional Info as it becomes available.

The motor of our vehicle failed while driving on the interstate. The vehicle is at a dealership for repairs and should be available for inspection. With little to no warning our truck quickly went from 70 MPH to completely shut down. We had to go from the left lane on the interstate to the shoulder. In the process we were very close to a collision. We were also hauling our camper (2023 Forest River R-Pod 153, which has a dry weight of 3,421 lbs and we had no water in our fresh/grey/or black tanks). When we merged into the right lane our truck was going so slowly on the interstate that we were almost hit and honked at before we could get to the shoulder safely. The problem was confirmed by the dealership that is working on it. The motor spun 4 rod bearings and it was a total motor failure. The vehicle was/is still under warranty. The manufacturer, I would assume, has inspected it as we are receiving a full motor replacement. That motor has been and continues to be on back order with no ETA for 2 months now. There were no warnings in how the truck was running. There were no warnings on the dash, warning lights, or any indication that our truck was going to break down.

[XXX] I was heading home from work, driving on [XXX] near [XXX] 2023 Chevy Silverado 1500 ZR2 broke down. I lost all power in my vehicle, besides brakes and steering, and had to coast into the breakdown lane. After restarting my truck, I was able to drive another mile on the highway until I lost all power again on the off-ramp. My truck was broke down, halfway in the road, and I could not start it back up to try and move it. I remained there in the subfreezing temperatures with no heat in my truck for over 1.5 hours waiting for a tow through OnStar that never showed. A state trooper eventually pulled behind me because I was blocking traffic and then proceeded to call a different tow company which arrived about 15 minutes after he called. Since that day, my truck has been at Colonial Chevrolet in New london CT waiting for a “nationally backordered” 6.2L engine. 53 days without my truck that I use for me and my business partner’s construction company, and no ETA for when the new engine will be arriving.

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.

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.
