After a day of heavy rain, the vehicle stalled at a stop light and would not restart. The steering wheel and transmission locked, preventing the vehicle from being placed in neutral, creating a safety hazard as the vehicle was immobile in traffic. No warning lamps appeared prior to the failure. The vehicle required a tow. The dealer confirmed water had intruded through the passenger side cowl/firewall seam due to inadequate factory sealing, tracking down and pooling directly onto the Body Control Module (BCM) mounted on the passenger side firewall. The BCM failed due to water damage, causing PATS desynchronization and the no-start condition. The BCM failure subsequently shorted out the starter motor. Dealer replaced the BCM, repaired the leak, and replaced the starter. Total repair cost approximately $3,200. Failed components are available for inspection at the dealership. This identical failure; passenger side cowl water intrusion leading directly to BCM damage — is documented across numerous 2021+ F-150 owner forums, indicating a widespread factory sealing defect at the cowl/firewall/inner fender seam junction.

This is a continuation/escalation of the federal safety agency complaint 11689917. My 2021 Ford F-150 has experienced repeated fuel-system/electrical fuel-pump failures. The vehicle previously stalled and later cranked but would not start, returning code P0627 “Fuel Pump A Control Circuit / Open.” The in-tank fuel pump was replaced at owner expense for approximately $1,400 at an independent service center in September of 2025, but the repair did not permanently resolve the issue. The vehicle has now again lost fuel pressure/propulsion while traveling approximately 50 mph on a two-lane highway in a similar manner to prior failures. I was able to get the vehicle off the roadway, and it required towing back to my residence. This is approximately the fourth or fifth fuel-related failure, including stalls at low speed and non-start conditions related to fuel in parking lots. The symptoms appear consistent with Ford/the federal safety agency recall 25V455 / Ford recall 25S75, but my VIN was not included in the affected group. I am concerned that the recall population may be too narrow or that the remedy does not address the full defect pattern.
