My 2012 Edge panoramic moon/sun roof made a pop sound today while I was closing it. Then it would not move forward to close. I would push the button to close it and it would "inch" forward a tiny bit, but then opened back up on its own. It opened fine. We forced it closed while pushing the button.. later, I closed the blind and it closed fine. I'm afraid to try the initializing procedure in case it opens again and won't close. Guess I will have to take it to my mechanic. I love my Edge, bought it used, but don't want to put a bunch of money ($4k mentioned before) to fix that issue.
