I would be tempted to have a visit with your dealership's "processor" and have the video in hand...., with a "oh, by the way".

I had the same problem with my 2016 2500HD upon towing my prior '05' Eagle in June of 2016, but not on a regular basis. It seems many GM folks were having this problem noted on some GM truck forums. I should mention that I never had an issue with my prior '02' GM 2500HD's 7-pin connector with the same TT.
My problem solving adventure ..........:
* The GM "Check Trailer Wiring" message is tied directly (only) through the 7-pin connector's #2 blue brake wire (trailer's e-brake switch and brake magnets). Thus one may still have functioning trailer lights, just no trailer brakes....., this is what I experienced.
* GM advised me that their OEM supplier "brand" 7-pin connector must be matched to the same "brand" 7-pin connector on the trailer. GM also stated a bad ground and/or connection within the trailer's brake system could be at fault.
* The optional GM OEM in-the-bed 7-pin connector wiring harness splice-in point could be at fault (I don't have one).
I checked my '05' Eagle's entire brake system wiring, magnets, and installed a new e-brake switch...., I would still get an occasional "Check Trailer Wiring" message (not on every trip).
I decided to replace my Eagle's original 7-pin connector/pig tail with a new Bargman brand, same brand as GM's. I didn't have any more message faults after the replacement.
With my new 2018 Jay Flight I have noticed that the Jayco supplied 7-pin connector isn't a snug fit in my 2016 TV's 7-pin connector, but I haven't had any "Check Trailer Wiring" faults yet......, but time will tell.
