NHTSA Complaint #11658453 — 2018 CHEVROLET SILVERADO 1500

In May 2023, my 2018 Chevrolet Silverado 1500 with the 6.2L V8 engine experienced a catastrophic engine failure at 82,986 miles. The failure involved the camshaft, lifters, oil pump, and other internal components. I paid $7,319.63 out of pocket to have the engine disassembled and repaired by a certified mechanic. I recently learned GM issued a recall (NHTSA Recall No. 24V266) for 2021–2024 vehicles with the same engine due to internal engine failures caused by crankshaft and rod bearing defects. Although my 2018 model isn’t included, the failure I experienced closely mirrors the conditions cited in that recall. I believe the same defect may exist in earlier models like mine. I’m submitting this complaint to urge NHTSA to consider whether the recall should be expanded to include additional affected years.
