Ford knew there was an issue back in 2021 as they so filed with your agency. Yet waited. Then warranty claims continued. Now, four years later they file as a safety issue, BUT have told me twice in phone calls that I can drive the truck, despite it could shut down on it's own while driving. I tow donated RV trailers to the North Carolina disaster, now I cannot as my dealership advised I not go on long trips. Ford refuses a like loaner, or any loaner at all. This is a Ford issue, not mine nor the dealership and Ford needs to either replace all suspected parts, have a resolution now or proved no charge loaners of like kind to all owners. This approach by Ford is totally unacceptable as they in two phone calls to corporate never once said to not drive the truck and the letter I received said they are not advising we park the truck

REAR CENTER HIGH MOUNT CAMERA ON CHMSL HAS STOPPED WORKING AFTER ONE YEAR AFTER PURCHASE

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.

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.
