On my 21 f350 while towing a 36 foot gooseneck unloaded I noticed a burning wire smell. And I realized I had no more trailer brakes. After diagnosis of the system I found the factory trailer brake controller had melted on the inside. Causing it to loose braking.

While driving my 21 F350 my truck would go into limp mode. The climate control stopped working, passenger window stopped, blind spot monitors, along with the mirror. After running forscan it showed every code possible. After an exhaustive search I finally found the main plug under the bed just above the spare tire. The wires inside of the insulation had corroded away to the point it had to be stripped back at least 1/2 inch before getting decent wires that wouldn't crumble when touched. This is a terrible place to put a plug that controls so much.

The contact owns a 2021 Ford F-350. The contact stated that the vehicle failed to shut off upon depression of the START/STOP button after several attempts. While driving to the dealer, several warning lights appeared on the instrument panel. The dealer performed a diagnostic test and discovered that the battery junction box was defective due to moisture intrusion. The manufacturer was notified of the failure and informed the contact that there was no recall on the vehicle. The contact was provided a case number. The vehicle was not repaired. The failure mileage was approximately 47,000.

On 7 Aug 2022, I lost cruise control, Navigation function (GPS0 and had problems with other elecrical functions on instrument cluster. I took truck to my local ford dealer; they rand Ford diagnostics on truck and it had 3 module errors listed. They cleared the codes and tried to get me to accept the vehicle. Road tested it and there efforts of clearing the codes did not fix any thing. Brought back in shop on 10 Aug 2022. Diagnostics ran again now narrowed it down to APIM failing 3 times in 2 days. Now deallership says they have to order part from California if they have them in stock. This truck only has 22,000 miles on it. Has had multiple failures of equipment for fuel system listing codes P0191 2 and threee times per day. Dealer will NOT attempt to fix that problem. Just says deal with it.

Check engine light comes on almost everyday. After at least 5 minutes driving, this trucks engine will shut down with out notice. Usually when making a turn or coming to a stop light. When this happens you loose all steering control. You have to shift to neutral and try and restart. This has caused me to almost rearend a highway patrol vehicle. Very dangerous. I have had this vehicle in to the local Ford dealership on numerous occasions; however they will NOT run diagnostics to see what is happening. Have ad independant mechanic and my scan tool run tests and it always shows code P0191 fuel pressure rail faault. Maintenance is always uptodate ad fuel filters changed by dealer every 5,000 miles. Dealer and MF not honoring warrenty.
