Well as said in the other complaints, engine shut off, did have warning lights a nd buzzers tho. Had it fixed by Ford, throttle body. Then it starts fuming smells of exhaust, oil, gas throughout the inside vents. These fumes make us so sick. Took it to Ford, they smell it can't find it. Take it back for the second time, same deal. I was told if there is not a light on or something leaking then don't bring it back. So it has been 3 mo later and the smell is even worse, took it to another ford dealer, same crap. So I called the Ford company itself. Well lot of good that did. Anyway took the truck back to the dealer I had been working with and they still can't find anything. They tell me they want to change the spark plugs which will cost me 600 to 1200 dollars depending on if they break any. They are still not sure this will solve the problem. Truck is running fine not acting up and they want to try to replace something that seems to be working fine. I have no clue right now what to do. I love my truck and just want it fixed and no one can figure it out. It does not have your regular spark plugs like normal cars do, they have coils on top each spark plug which from what I have heard is a B***ch to change, they can break off leaving them stuck in there. So if they break while they are changing the ford charges you for that. Seems ford is not standing behind their new so called product. If they can't do the job then they should not sell the crap.Any how my truck is still not fixed and I am still getting sick from it.
