What finally happened here? I'm experiencing the same issue. Dealer has had my truck for 2 months and has basically pushed it off to the side explaining that it has to be the alarm or radar that is tapped into the mirror harness. I told them neither caused an issue for the last 3 years that I've had it so it would be a waste of time exploring those 2 things. They did some updates, no luck. I picked one of the crappy dealer service centers it appears. Mopar is supposed to be assisting but I haven't heard anything back from them since they agreed to appoint a case manager to go between myself and the dealership.
