I'm still having this problem! I replaced the connector cord from the RV to my RAM, just to eliminate the possibility of loose/corroded/screwed up connectors. still have the same problem.
There have been LED bulbs switched out with the stock bulbs inside the RV, but I don't see how that could cause this problem.
Once we are on the road, everything works great with no indications of any problems. Then I will get a warning to check the trailer connections. After a moment or two, that will then go away, and then repeat a minute or two later. After multiple repeats, I get a trailer brake failure warning. Then that will go away and we start over again.
I sincerely appreciate all the great suggestions!
