Hello, i own a 2007 edge now and just unloaded a 2015 focus and have had the same issue Fords inability to admit to any mechanical issues untill the car is literally towed in.
I love my Edge and have put up with Ford because overall i love the car. 174K miles (i drive freeway a lot) but I have had one rear drive unit (sealed) fail, the brake Booster fail and now another sealed drivetrain unit the Ptu has failed thats a lot of trouble for one car and the way i drive. We had to get rid of the focus due to the double clutch disaster of a transmission and i warn everyone off any Ford that has that trans.
I dont expect Ford to fix my edge anymore due to milage but to put a car on the market in the US with drivetrain parts that are sealed and cannot be serviced is ridiculous, and when you experience trouble the dealers choice of reasons is you dont know how to drive or its supposed to do that until the warranty runs out. A 36month warranty is pretty self serving. After the financial crash we wanted to support Ford but the company has really disappointing record with customer service in our home.
I hate to support the offshore carmakers but they are standing behind their cars better and actually choose dealers that have been much better at supporting their product. Due to our experiance with the last two fords i have had to purchase Hyundai products. I still love my edge and it runs great but I am looking at a new PTU to the tune of about 2K this was an engineering failure solely in Fords Lap and they know it since the overseas PTU units are not sealed so you can change oil its not rocket science guys a 1.00 plug would have stopped all this animosity on line concerning this system.
And for the Ford apologists that will say these are not big issues it only happens once in a while look on utube and all the repair vids for Ford PTU seals failures etc if you own an all wheel drive ford in this agegroup you will have trouble. Same with the Double clutch trans, the fix dosent work just ask the mechanics somewhere they cant be heard.
