Example complaints

“While traveling vehicle in motion electric tailgate spontaneously released damaging the tailgate and tow vehicle on 8/8/2020, 8/20/2020 and 9/3/2020. Tailgate released on several occasions while towing on city streets and highway.”
NHTSA complaint #11353197, filed 2020-09, 4,800 miles“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.”
NHTSA complaint #11757321, filed 2026-08“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. …”
NHTSA complaint #11723712, filed 2026-03“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.”
NHTSA complaint #11672559, filed 2025-07“The contact owns a 2020 Ford F-350. The contact stated that Ford Pass failed to connect and communicate with the system. The telematics control unit (TCU) B157D 89 was inoperable. The information screen was blank. The contact stated that the failure was related to SSM 49292 and Customer Satisfaction Program 24B47. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline. The failure mileage was approximately 170,000.”
