I noticed this about a week after I purchased my 2007 Edge last December. When I stop on a slight incline, if I let off the brake it will start to roll as if it is in neutral. When I took it in for routine maintenance another customer came to me and ask If I owned the 2007 Edge. She said she had one also and almost had an accident when she was stopped on a steep hill and it rolled backwards and almost hit another car. She was there to have the dealer check out the problem and they told her they did not have a repair for the problem. For now I know to make sure and keep the brake applied until I and ready to accelerate and move. Even though this is definitely a mechanical problem with this vehicle.

Here's my story...... On my way to work I felt my Edge struggling switching gears. So I turned off the radio to really listen. And I could tell the transmission was slipping. About 5min later it was a lot worse. Once I stopped at a light and began to go the transmission was just revving up but not going into gear.

I took it to Firestone who confirmed, for $67, that it was the transmission. Firestone does not work on transmissions. So, Then I took it to the dealer for $99 for them to confirm it was the transmission. They told me that I would need to replace it. So 101045 miles later and a brand new $3900 Transmission. Not really Happy.
