Anyone having challenges with their trailer and Cybertruck?

The truck can see the trailer and even do the light check without issue.
It shows the blue trailer icon light.
The second I put the truck in drive it gives a fault error.

Probably a long shot, but I'd check to see if the blue connector on the inside of the 7-pin connector is snapped all the way in. If you have long arms, you should be able to reach in and wiggle it. If that doesn't work, maybe check the resistance across each of the trailer pins to see if there is a short in the trailer wiring. Do you get a blue trailer mode icon on the dash prior to selecting drive?

have you been able to verify that the trailer breaks are functioning correctly on another vehicle?

Does that trailer even have trailer brakes?

Yes, the blue connection icon light comes on. I'll check the wires and grounding to confirm nothing is loose

Yes, the trailer works without issue on my gas truck. No issues there

Grounding issues notoriously plague trailers. I think the manufacturers only hire incompetent drunkards for both assembly and testing.

Always good to do a sanity check... hmmm, I'll defer to better expertise on the forum. I've towed a few trailers with brakes so far and haven't had this come up.

Yes, it has brakes. Can haul up to 7K pounds

Thanks, I'll check and confirm the grounding on the trailer

Try moving forward and hitting the trailer brake.

Church. I have wired and rewired my utility trailer multiple times, ground faults are a consistent problem and like all electrical issues they are notoriously hard to track down. I pull my tractor and UTV to the field where grass and brush plague me constantly.
