Why do you wait? if one person complains, much less numerous others it should be fixed by Ford due to faulty parts. Of course now I will have to have it fixed and it is expensive! I use to have all the faith in the world in Ford but no more.

Wonder how long before Ford acknowledges and recalls or at least fixes the problem when someone takes in the car.
