“This car has had a recall for almost year. I’m am terrified to drive my truck especially with my kids in it. Sometimes if I press the gas trying to cross traffic, it takes a while to go. Also sometimes it won’t crank up and start. It takes awhile few tried. My back up camera doesn’t work the way it should”
NHTSA complaint #11682653, filed 2025-08“All of my rear lights stopped working with no warning. My blind spot monitoring and cross traffic detection also stopped working. This is a serious issue as the light go out intermittenly without warning. Especially dangerous at night. Dealership thinks it might be a faulty harness. Dealership thought they fixed it by cleaning contacts but the very next day they went out again while driving in a snow storm. Luckily no one was behind me because they would not have been able to see me.”
NHTSA complaint #11706808, filed 2025-12“My F250 was in service for fuel system replacement and to fix both side mirrors which wouldn’t go down after going up. Shortly afterwards I noticed the rapid turn signal you get when tail lights are out. This happened while using a trailer. The trucks rear lights weren’t working at all but trailer lights were. Also was getting the blinds spot and cross traffic alert faults on instrument panel. Dropped off for service. They found a loose trailer plug and reset some things and got it all working again. …”

NHTSA complaint #11709898, filed 2026-01, 48,000 miles“Both the driver and passenger mirrors will not fully adjust. The mirrors need a different adjustment for standard driving and when towing a travel trailer. Neither mirror will properly adjust for towing and non towing applications. The lack of proper mirror adjustment causes a safety issue as the driver cannot see things in their full scope due to the mirror misalignment. I have almost had two accidents due to the mirrors not being able to be properly adjusted. Ford is aware of this issue on 2017 to 2023 F150, F250 and F350 trucks with the tow mirrors. …”
