I got my 2007 Edge back same day, they said they were now all over this problem. They replaced the PTU cover seal, passenger side PTU intermediate shaft seal, deflector(?) and replaced the dylithium crystals. OK, the last one was made up, we'll see if this fixes the problem or if I am heading back to the dealership like so many others on this forum. The dealership is Pacifico-Marple Ford in Broomall, PA, awesome dealership, great sales and service people. I will report back if problem comes back.
