Typical electrical symptoms owners report

  • Some trucks produced white smoke followed by large flames from under the hood after a drive, with the fire starting near the engine bay.
  • Other owners reported smoke filling the cabin with the center console and dash melting, leaving electrical functions dead afterward.
  • Trucks failed to start days after purchase, with a diagnostic alert pointing to a relay that needed replacement before the truck would run again.
  • Headlights suffered from a design that let wet snow pack into the lens area, blocking light output during storms.
  • Radio volume fluctuated on its own after water leaked through the rear sliding window into the stereo amplifier, causing an electrical short.
  • The tailgate opened and closed on its own without driver input, including while preparing to tow a trailer.
