2020 Ford F-350 SD electrical problems

Filed Aug 16, 2026 · Electrical · AZ

The backup camera on the tailgate fails about 50% of the time when shifting into reverse. The screen is black. When it fails, I can sometimes get it to work by opening, then slamming the tailgate. I suspect that there is an intermittent open circuit in the camera system. This presents a dangerous situation when trying to back this very large dual rear wheel vehicle. This is not related to the current recall for another issue with the camera when backing into a darkened area.

While towing any trailer with electric brakes it appears the integrated trailer brake controller is briefly applying trailer brakes unexpectedly. Very brief but very hard, resulting in an extreme rearward pull on the truck. It happens at exactly 60 minute intervals, at any speed, uphill, downhill and level flat road. I've had the trailer 7 way plug and wire inspected, no problem found. Next step will be to have Ford dealer inspect truck electronics.

Vehicle produced symptoms over time: Loss of Ford Pass connectivity, Inconsistent turn signal function, occasional dashboard alarm for Open Driver Door while driving, unwarranted security alarm triggers when still at home. Second to last incident was an unwarranted security alarm that triggered, and was unable to be stopped by use of the security controls (lock/unlock, alarm key button). Horn "wore out" as if fuse burned. Disconnected battery to stop. Two days later, after reconnecting the battery I drove the vehicle, Horn was not functional, and I was unable to stop the engine. Once started, the vehicle did not turn off, even with key completely removed from ignition switch. This was repeatable, every ignition cycle, thereafter. I drove to the dealer, that morning. The dealer mechanic was required to shut off the engine. Dealer mechanic diagnosed failed Battery Junction Box. After Repair, Mechanic diagnosed faulty Body Control Module. Dealer mechanic also recommended replacement of full "Main" wiring harness, interconnecting the two. The cause for all failures was corrosion and electrical shorts due to water ingress. I am aware Ford has issued numerous TSBs and recalls for faulty BCMs, in the same age range as this vehicle. Also, TSBs for water intrusion into the BCM. The mechanic took photos of corrosion on both the BCM and main wiring harness. My prior vehicle was a 2011 Ford F-150, with the same 6.2L engine. No such faults were experienced up to Nov. 2023 sale. Photos of the corrosion on main wiring harness and BCM attached. Dealer has possession of the vehicle. Repairs in progress. Ford has declined support for faulty components; Recalls not associated with this vehicle. Estimated repairs to date on 6 year old vehicle on critical electronics in excess of $7,000.

The connectors (part #1 HUZZ-14S411-HB) and (part #2 HUZZ-14S411-FA) are located in on the frame of the truck where the back wheels throw water towards when driving on wet terrain. They tend to hold water which causes electrical damage. This is happening on multiple ford trucks from 2020 - current models. This is causing tail light, AC, radio and other failures to occur.

Computer-dash info screens and drive modes. I am unable to change or check onboard dash info upon starting vehicle. Dash does not hold settings one day to the next. Unable to get into or change settings such as trailer settings-so can’t change braking effort-dangerous when hauling 20,000# trailer! Cannot put truck in tow mode or any other mode-defaults to slippery road mode. Again dangerous. Says hill start assist, hill descent assist and pre-collision assist is unavailable . This is all very potentially dangerous especially when hauling! Dealer cannot find problem. After truck is driven a while settings can be re-entered-truck has to be turned off first. Unable to load video of start up.
