In October 2024, my 2016 Chevrolet Silverado 1500 LT, at 96,000 miles, experienced a lifter collapse which caused sufficient wear to the camshaft that the engine needed to be replaced, which was performed. The malfunction indicator lamp turned on and the truck was driven an additional 2 miles to a safe location and subsequently towed to the repair shop. Before then, there had been no indication that a lifter had collapsed or that there was damage to the engine sufficient to warrant a replacement.  In November 2025, I experienced another lifter collapse (on the replaced engine). While the mechanic recommended an engine replacement, the warranty company only authorized a replacement of the affected side cylinder head and lifter, which was performed.  In February 2026, I experienced another lifter collapse, and the truck is currently being evaluated by a repair shop.  These failures have 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 tried to address 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.","products":[{"type":"Vehicle","productYear":"2016","productMake":"CHEVROLET","productModel":"SILVERADO 1500","manufacturer":"General Motors, LLC"}]}]}
