I had the same thing happen to me but without the trailer failure message, also the module clicks non stop even without a trailer connected, this started immediately after the last update Sept 17 2025 ITRM-25.A03
The dealership says they don't have a fix and are waiting to hear from Ford techs
What was the issue ? Same thing just happened to my truck, the steering wheel will not return to center whe turning left, it will stay locked at 10 o'clock and shudder/grind when turning right, the truck will do this intermittently
My new 2024 F-150 STX does the same thing, the windshield fan and the floor fan work great, but when I change it to the regular vents the speed is way slower
