Vehicle: 2022 Chevrolet Silverado 1500 Trail Boss, 6.2L V8 L87 engine Date of Incident: Friday, April 19, 2025 Mileage at Time of Failure: ~30,000 miles Location: Route 1 (high-traffic highway) While driving at highway speed, the vehicle suddenly shut down without warning. The RPMs dropped to zero, and I had to quickly merge across lanes with no engine power, creating a serious safety risk to myself and other drivers. There were no warning lights, sounds, or prior symptoms before the failure. I had the truck towed at my own expense to a trusted mechanic, who confirmed that the engine had seized. It has since been transferred to a certified GM dealership for teardown and repair. This failure appears consistent with ongoing reports and an active NHTSA investigation into the 6.2L V8 L87 engine, specifically related to oil pump failure and oversized lifter bores, which can cause catastrophic engine failure without warning. I am concerned about the future reliability of this vehicle, especially since powertrain warranty coverage is limited. Had I known about these known engine issues, I would not have purchased this vehicle. I will be notifying my bank, which holds the lien, as this situation also impacts the value and security of their asset. I intend to request part numbers and full documentation from the dealership to ensure the engine is not replaced with the same potentially defective components.
