Update:
Sorry, forgot to give an update, although it's not a final update...I was all set to attempt to disconnect the battery as suggested by the dealer and of course when I went to start the Edge, the display was fine. I did take it to get an oil change and state inspection at the dealer and said they would take a look at it...said no codes were showing and it appears to be fine. So all was well until I used the remote start today (which is what happened the last time) and even though the display was blank, I could tell that it was on.
I turned off the vehicle, opened and shut the door and restarted and it was fine. So, I would think that the remote start has something to do with it - any suggestions before I call the dealer?
