NHTSA Complaint #11716097 — 2016 CHEVROLET SILVERADO 1500

I am reporting a manufacturing defect involving General Motors’ Active Fuel Management (AFM) system that caused catastrophic engine failure in my 2016 Chevrolet Silverado (VIN: [XXX] ). At approximately 78,000 miles, my vehicle experienced piston and lifter failure requiring full engine replacement. This failure occurred without warning and aligns with thousands of consumer complaints regarding AFM-related oil consumption, lifter collapse, and engine damage in GM vehicles. This is a known design defect that GM has addressed through Technical Service Bulletins and engine redesigns, yet many consumers continue to experience premature failures at low mileage. This defect presents a safety and reliability concern, including loss of power while driving and significant financial burden to vehicle owners. I respectfully request that NHTSA investigate this ongoing defect. Sincerely, [XXX] [XXX] [XXX] [XXX] VIN: [XXX] 2016 Chevrolet Silverado INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
