2020 Ford F-150: multiple warning lights

Filed May 15, 2026 · Electrical, Engine · MI

I was driving and slowing down for a stop sign and the engine shut off by itself while still moving at appx 10-15mph. The display had several warning lights appear, and the message "Auto Start Stop, Shift to P, Then Restart Engine". I have the Auto Start Stop disabled on my vehicle, so there was no reason for my engine to shut off while decelerating. I searched online for potential causes and discovered that there are numerous incidents of this happening (engine shutting off while moving) to drivers that have deactivated the auto start stop on their vehicles.

While driving in the rain, my vehicle had a complete electrical failure. I could not accelerate or even turn the vehicle off. Because of this I could not move my vehicle off the highway. Fortunately I was not hit by the vehicle behind me, and was not in a turn. he Several warning lights came on. After being towed to a dealership, it was found that the factory windshield was leaking into the passenger side area where the Body Control Module (BCM) is housed. This flooded the unit and completely killed the truck. It was surprising to me that rain had the ability to completely render my truck useless. The manufacturer would not cover any repairs as they claimed windshield leaks were a maintenance issue.

This appears to be a possible PCM relay failure or electrical system malfunction . This seems to be a documented issue out there on various websites and forums. I was with my wife and son when the vehicle started running extremely rough and lost nearly all power on a busy roadway. This caused a very dangerous situation for my family in attempting to get the vehicle off the main roadway. Multiple dash lights came on and the system advised of "park brake limited service required", "Hill assist not available" and "drive modes not available". After getting the vehicle off the roadway and parked, the vehicle stalled and would not start or run. I have not taken this to the dealer yet to determine the issue.

Ford eliminated the engine cover in 2019 exposing the engine wiring to the elements. Since the wiring insulation is made from soy this allow for rodents to clime up into the engine compartment and chew at the exposed wires. This can disables the vehicle or set a vehicle engine lights at the owners expense. In my case the vehicle lost power on the freeway and I had several lights come on. The top speed dropped from 70mph to 23mph. Brighton ford did repair the vehicle at my expense. Going forward even though the repair has put the vehicle back on the road, the potential problem still exist. Ford customer care said there is no solution available to this problem I have opened a case but I don't believe anyone is looking at it. I also check 2021 vehicles and it has the same issue.
