NHTSA Complaint #11468999 — 2022 FORD F-450 SD

2022 F450 King Ranch will not recognize an electric over hydraulic brake system on the trailer. It will recognize it if you connect while running. Once you shut the engine off and turn it back on it disconnects and will not recognize the trailer until you get out and go back to the plug and unplug and plug it in again. The 2021 F450 will work with the trailer. The dealer tried hooking up (4) different 2022 F series and they all did the same thing. Have been emailing every email address I can get ahold of at ford. Field service engineer came out on 6/8 and he cannot figure out the issue. This truck was taken in after the brake controller recall on 4/18/22. First attempt updated software on 4/20/22. Supposed to fix. Still not fixed as of 6/13/22. Also had our 2021 Gator Trailer inspected for any issues. There were none. The fact that Hardy Ford hooked up 2022 F150, F250, F450 to the trailer and none of them would recognize and electric over hydraulic brake trailer system.
