NHTSA Complaint #11443523 — 2021 FORD F-150

The Pro Trailer Assist program won't load or work along with constant electrical lamp fault messages when trailering my boat. This is a safety concern because you can't tell if the trailer lights are really working or not while driving. I also experience the turn signals blinking really fast like a bulb is out - when none are actually out. The local dealer's electrical technician has reproduced and confirmed my issues. The manufacturer is aware of my problem and is currently offering to put me in a 2022 truck that will be built in February. The Pro Trailer Assist program never would load or work from day one. The electrical lamp fault messages started as soon as I trailered my boat. All the lamp fault messages and fast blinking turn signals only happen while trailering my boat. The local dealer had my new truck forty days and replaced the APIM Module twice with no success. Mileage then (328), mileage now 1,255.
