I’m having the exact same issue - it started just a few months after purchase. Wondered if there could be a recall or other explanation. Thanks for posting so we know we’re not alone.
I have been trying to find this answer. I am thinking of using the aux connection in the back to power the trailer wiring. It would mean you could turn the power to the wiring off and on, but I am wondering if it is the right gauge. Anybody looked into this or tried it? We would still connect...
