During towing of 10,000lb trailer, the trailer brakes cut out during heavy braking and the dash displayed "wiring fault". Also, sometimes during normal braking, the trailer brakes will cut in and out, if you watch the gain meter during these episodes, the gain meter will also cut in and out. My and my families safety was definitely put at risk and now we were fully dependent on only the truck brakes to stop our vehicle and trailer. The dealer checked the vehicle on 5/9/23 and say there is nothing wrong with the truck. There is an active safety recall (22S17) covering trailer brake controllers for Super Duty vehicles, however, it seems to be limited to model year 2022, even though my vehicle was built at the same plant during the same time period covering this recall. I intend to have the dealer perform the required repair at my expense, and hopefully this recall will be expanded to cover my model year. This is a very dangerous situation.

When towing a trailer, the Trailer brakes stop working. the brakes, using the pedal and lights all work perfectly on truck and trailer. But if you squeeze the brake control paddles, you immediately get a trailer disconnected message and although all lights still work, the brake controller does NOT. Then sometimes, just driving and perhaps stopping at a gas station, the trailer brakes also stop working and you don't realize until going down a hill. This has happened multiple times. I start out just fine and then ?
