NHTSA Complaint #11706170 — 2018 FORD EXPLORER

Intermittent failures of both front turn signals and parking lamps due to wiring failure. The turn signals and parking lights on both sides of the front end of the vehicle sometimes failed to illuminate correctly. Upon investigation, failed wiring was found on the jumpers between the main engine bay harness and the lamp sockets. The wire insulation had become brittle and was flaking away, causing electrical shorts. The same failures were present on both sides. Only that short jumper segment experienced the issue, all other wiring in the engine bay was fine. The faulty wiring jumpers are available for inspection upon request. Safety was put at risk because the turn signals would not reliably signal driver intent. I am an independent mechanic, and discovered the issue while performing other work in May 2025. No one else has investigated the vehicle or component. There were no warnings or symptoms prior to the failure.
