Today about a hour after leaving the house my dash displayed "Trailer Wiring Fault". I went to pull over to check the trailer connection and when I applied the brakes the trailer started chuck very violently, felt like brakes came on really hard and then off and back on. Pretty scary. I turned the gain down to 4.5 on trailer brake but it still did it not as violent. We have a 2021 2930RL Solitude S Class. Has anybody heard of this and any ideas?
