NHTSA Complaint #11674598 — 2014 CHEVROLET SILVERADO 1500

I am writing to report a significant mechanical failure with my 2014 Chevrolet Silverado, which I believe warrants further attention due to its potential safety implications and its connection to a widely documented defect affecting many GM vehicles equipped with Active Fuel Management (AFM) systems. The engine suffered lifter and camshaft failure. This is a well-known problem with GM trucks using AFM systems and can pose a safety hazard, particularly if the vehicle stalls while driving. Failed Component: The engine’s valve lifters and camshaft failed. The components and repair documentation are available for inspection upon request. Safety Risk: This failure caused loss of power while driving, creating a risk of stalling in traffic, which could endanger both myself and other drivers on the road. Confirmed Diagnosis: The issue was confirmed by the dealership where I service my truck, Team Chevrolet in Las Vegas, NV. They identified the lifter and camshaft failure as the source of the symptoms. Inspection History: The vehicle has been inspected and diagnosed by the repair facility. I reported my concerns directly to General Motors and formally requested goodwill assistance and an extended warranty to cover the repairs. However, GM denied my goodwill and extended warranty request despite widespread reports and TSBs. Warning Signs: These warning signs began to show June, 2025 after picking it up from the service department at Team Chevrolet as it had been serviced. The truck was taken back to the dealership within 30 minutes of picking it up.
