Matt,
I hope you see this. Not sure how often you look at the forum.
I purchased my 2012 Edge in March of 2012. The first week I drove it I experienced similar problems to yours, took it in to the dealer they test drove it and said it was me. Kept having the same problems, finally after having them look at it several times took it in Dec. 5, 2012 told them to keep it and drive it until it acted up for them sure enough it did after they drove it for a week. They started replacing parts in the transmission with no success, finally Ford agreed to a new transmission, after getting the car back on Jan. 5,2013 (right they had it a whole month) but did provide a rental car) with the new transmission, on Feb. 7 back to the dealer with a transmission leak. After they supposedly fixed the leak , went back for an oil change about a month later, and after being there for 3 hrs they finally came and told me they were replaced a bad seal on the transmission. I was upset at this point because they had told me they fixed that previously. The transmission still acts up occaisionally and I have filed a BBB claim for the lemon law against Ford.
Hope this is useful for you.
