There was a recall on this veh. over a year ago and they still do not have the parts to repair it. My fuel milage went from 13.8 down to 9.6 and still going down. I have called Ford about this and they say they are still waiting on parts. I reminded them it has been over a year now and should have had the parts in a long time ago.
