My complaint is about my rear seat belts, I used the middle rear seat belt from 2003 until it broke in 2004. The middle is where I put my son's car seat. I always made sure it was in right, it moved no more then an inch and I always locked the seat belt. I didn't take the car seat out much so that is why I don't understand how it could break so fast. I had to move my son to a different seat until I could get it fixed, and then the rear seat belt on the passenger side started to act up, when it was time for the seat belt to retract it wouldn't you had you use your fingers and push it in. I have not gotten it fixed yet. I cant afford to and Ford wont pay for it. Both times I had Ford take a look at the seat belts, and the only thing they did was gave me an estimate to replace the seat belt. My thoughts on this is the seat belt should last longer then the car.
