NHTSA Complaint #11496501 — 2018 FORD F-150

Vehicle had electrical issues - Diagnosis by dealership was water damage to the Body Control Module. This module is inside the cabin on the front passenger area by their feet/legs. The issues included - flashers goin off, horn going off, truck bed gate dropping open - while parked and while driving down highway, and entire vehicle just shutting down while ALL of the issues happened at once. People have been put at risk by the gate dropping and the immediate shut down of an operating vehicle. The dealer was able to reproduce the problem. I had it happen twice. I have since identified that it is something that is a known issue on F150 forums. So much so that the likely cause of the water damage has been identified, and forwarded to the manufacturer. They are not fixing the issue. Manufacturer's dealership technician identified the water damage as the root cause. Required a replacement Body Control Module. Possible warning signs: Noted by myself and others. Emergency flashers randomly going off. Power drain on batteries. Horn going off randomly. Root cause: Unsealed seam between body panels under the hood in the engine bay. Leaking water falls on firewall and then onto the Body Control Module electrical component. Shorting will eventually ensure. This can happen any time. F150 forum thread documenting the likely culprit leaking seam: https://www.f150forum.com/f118/water-leak-cowl-seam-474781/
