Rearview System Braking problems of the 2022 Ford F-350

While traveling with my fifth-wheel camper attached, my 2022 Ford F-350 super duty (6. 7l power stroke) suddenly developed a complete no-crank condition. Prior to the failure, the vehicle displayed multiple electrical warnings, including u0100 (lost communication with pcm), high engine temperature, advancetrac, blind spot system fault, hill start assist, and pre-collision assist warnings. The vehicle ultimately became disabled and would not crank or start, leaving me stranded away from home while towing a trailer. Repair description after troubleshooting the vehicle, I discovered severe internal corrosion inside the under-hood battery junction box (bjb). The corrosion appeared consistent with Ford technical service bulletin 23-2133 regarding moisture intrusion into the battery junction box on certain 2020–2022 super duty trucks. I purchased a genuine Ford replacement battery junction box from a Ford dealership and installed it. Immediately after replacement, the vehicle started normally and all warning messages disappeared. I retained the failed battery junction box and have photographs documenting the internal corrosion. Safety concern my concern is not simply the repair cost but the safety implications of this failure. The vehicle became completely disabled while towing a fifth-wheel trailer during travel. A sudden electrical failure affecting the battery junction box can leave occupants stranded and may create hazardous situations if it occurs in remote locations or during travel. Because Ford has issued a technical service bulletin addressing moisture intrusion into the battery junction box, I believe this condition should be evaluated to determine whether additional action is warranted.
