I found this TSB, No. 23-018-16, dated April 26, 2016, that will help owners of Challengers that have malfunctioning sunroofs (i.e., may open, close or vent by itself while driving or perform an auto reversal). The bulletin applies to vehicles built on or before July 02, 2015 (MDH 0702XX) equipped with Power Sunroof (Sales Code GWA) and equipped with Universal Garage Door Opener (Sales Code XGD). The cause of the problem is a tight or stretched wiring harness (causing connector stress), that is pulling on the connector pins causing an intermittent connection.
