   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.

The contact was informed that the CP4 pump replacement was not covered and needed to be replaced at the owner's expense. The manufacturer was notified of the failure and contacted the dealer, but no further assistance or information was available. The vehicle was not repaired.

6. Filed Jul 8, 2026Failure Jun 1, 2026Munds Park, AZElectrical system, Service brakes

   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.

7. Filed Jul 1, 2026Failure May 30, 2026Phoenix, AZPower train

   The transmission began malfunctioning by having hard shifting issues and losing power in some gears. An indicator on the dash lit up resembling a mechanics open-end wrench. Research online showed that the vehicle should not be driven and taken immediately to a mechanic or dealership. If driven especially pulling a heavy load like the fifth wheel that I bought the truck to tow the transmission could fail causing a serious safety issue. I immediately took the vehicle to a certified Ford dealership. At the dealership they informed me that parts in the transmission had failed and that it was the same exact condition as shown in recall 20S33. The noted recall was for trucks manufactured in January and February of 2020. My truck was manufactured March of 2020. The time warranty had expired for the vehicle but the mileage warranty was for 60,000 mi and the truck failed at $29,800. The transmission failed due to a manufacturing defect but I was billed over $9,800 for the repair. I have attached photos of the work order and receipt.

12. Filed May 8, 2026Failure Apr 29, 2026clearwater, FLEngine, Fuel/propulsion system

    The component/system that failed or malfunctioned is the SCR (Selective Catalytic Reduction) NOx Catalyst Efficiency system, triggering DTC P20EE – SCR NOx Catalyst Efficiency Below Threshold (Bank 1). This issue began immediately after Ford Recall 24S78 (PCM software update) was performed on April 29, 2026 at Ferman Ford of Countryside. The truck had zero emissions or check-engine issues prior to the recall flash and was perfectly maintained to Ford standards with Howes diesel treatment every tank. The problem has been reproduced and confirmed multiple times by the dealer: After the May 4 PCM reprogram per TSB 21-2248 After replacement of both NOx sensors on May 5 (code returned in under 17 miles) After replacement of the DEF injector (code returned again) The dealer only performed one manual DPF regeneration instead of the two required by Ford SSM 49202 and pinpoint test RD15, and they did not complete the SCR Parameter Reset. They are now quoting an additional ~$2,000 out-of-pocket for a DPF replacement after partial goodwill assistance was approved. The vehicle has been repeatedly inspected and repaired by Ferman Ford. No independent inspection yet. Ford Customer Service has been contacted and partial goodwill was approved, but significant out-of-pocket costs remain. Warning lamps/messages (Service Engine Soon light + “exhaust emission control system is not operating as expected”) first appeared immediately after the April 29 recall PCM flash and have continued ever since. Safety risk: A loss of motive power, entry into limp mode, or reduced power while driving could result in a crash or inability to maintain highway speed. This appears to be a direct consequence of the Recall 24S78 PCM software update tightening emissions monitoring. All repair orders, photos of warnings, and supporting documents are attached for your review. There is 12. I was not able to upload the last of the documents.

19. Filed Mar 20, 2026Failure Mar 9, 2024Grantsville, UTPower train

    I am the owner of a 2020 Ford F‑350 equipped with the 6.7L Power Stroke diesel engine. My vehicle is subject to an open safety recall, NHTSA 24V957, involving the high‑pressure fuel system. I have been informed by an authorized Ford dealer that there is currently no effective repair remedy available. While I have not experienced loss of power, my vehicle has exhibited abnormal transmission shifting behavior beginning around 40,000 miles. This concern was documented by the dealer and described as normal operation. The condition persisted and was documented again around 60,000 miles, although the dealer stated they could not replicate the issue. Given the unresolved safety recall and ongoing powertrain behavior, I am concerned about vehicle safety, drivability, and long‑term reliability, and I am submitting this complaint to document the risk before a safety‑related failure occurs.

    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.
