NHTSA Complaint #11616933 — 2017 CHEVROLET SILVERADO 1500

I am filing a complaint regarding an electrical fire in the junction box of my 2017 Chevy Silverado 1500. The issue began when the front passenger side marker light would not turn off. I disconnected the battery overnight to troubleshoot the problem. However, when I reconnected the battery the next morning, an electrical fire occurred in the fuse junction box under the hood. At the same time, the engine unexpectedly attempted to turn over and start on its own. I immediately disconnected the battery again to stop the fire. Upon inspection, I found that several wires, plugs, and the top half of the junction box had sustained significant damage.
