THE TRUCK HAS BEEN BACK TO FORD MANY TIMES FOR DRAINING THE BATTERY. IF IT IS PARKED FOR 2 TO 3 DAYS I WOULD HAVE TO JUMP START IT. THE DEALERS COULD NOT FIND THE PROBLEM AND KEEP REPLACING THE BATTERY. AFTER IT WAS OUT OF WARRANTY PAID OUT OF MY OWN POCKET TO FIND THE PROBLEM STILL COULD NOT FIND. I HAVE A VIDEO OF THE TRUCK IN12/11 OF THE HEATER/DEFROSTER RUNNING AFTER THE TRUCK WAS PARKED FOR 3 HOURS WITH NO KEYS IN THE TRUCK. ON 5/16/2012 THE TRUCK WAS PARKED IN MY DRIVEWAY AND CAUGHT FIRE UNDER THE DASH. *TR
