NHTSA Complaint #11715397 — 2017 CHEVROLET SILVERADO 1500

The contact owns a 2017 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed, there was an abnormal metal-on-metal sound coming from the engine. No warning lights were illuminated. The contact stated that on a separate occasion, the vehicle failed to accelerate as intended while depressing the accelerator pedal, and the engine sounded rough. The vehicle was taken to two different independent mechanics, who diagnosed that the Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) were impacting the lifters, which impacted the camshaft, and scraped the cylinder walls, causing the engine to fail. The vehicle was not repaired. The vehicle was then towed to the dealer, who confirmed the engine failure. The vehicle was not repaired due to the cost. The vehicle was towed to the residence and no longer driven. The failure mileage was approximately 156,000.
