My 2007 SEL AWD has just rolled over 36,000 miles and I discovered the leaking fluid 2 days ago when I was having an oil change. I took it to the dealer that day and was told that it was probably the PTU Seal/RTU Seal. They replaced this in no time, which leads me to believe they have repaired several of these. I love the Edge's styling...and it has been a very good car up until this point. Although, the car doesn't get great gas mileage like advertised...but something I can live with. What I cannot live with is a constant repair of a seal! This is completely unfair to the consumer!
