I think it’s unlikely that my Mazda is responsible for this problem, but throwing this out there hoping someone can steer me in the right direction.
I have a 2020 CX5 GT. About a week ago I had a class 3 hitch and wiring installed at UHaul. Later that day I picked up a new utility trailer, checked the lights before driving home and everything was working correctly. A few days later I hooked up the lights again and they did not work, no turn signals, no brake lights, and the running lights were on (but dim) even when the ignition was off. I went back to UHaul, they replaced all the wiring, and the lights worked correctly again. I hooked up the trailer and lights again today for a 500 mile drive. Lights were working fine. Now at a hotel and I notice the running lights are on again with the ignition off. The left turn signal works but right one does not. Similar but slightly different than the first failure.
Its hard to imagine that 2 wiring harnesses were defective and failed like this. I wonder if there could be an intermittent short in the wiring on the trailer itself that blows out the controller module? As I said, it’s a brand new trailer. All the lighting is low current LEDs.
Any ideas?
