THE CRANK SHAFT POSITION SENSOR HAS FAILED FIVE TIMES AND REQUIRED REPLACEMENT. ON TWO OCCASIONS WHEN THIS SENSOR FAILED IT RESULTED IN TOTAL LOSS OF POWER WHILE THE CAR WAS ON THE ROAD AND IN TRAFFIC. THIS COULD HAVE RESULTED IN CRASHES AND INJURY.

WHEN PARKING OR STOPING, TURNING THE KEY OFF, REMOVING THE KEY THE ENGINE WILL KEEP RUNNING. THIS WAS REPORTED TO FORD UNDER WARRANTIES. THIS IS EASY TO CATCH IN A CLOSED GARAGE BUT IMPOSSIBLE TO DETECT OUTSIDE (NO NOISE WHEN WALKING AWAY FROM CAR) 6 TIMES IN THE LAST 3 YEARS.

ABOUT A MONTH AGO IN APRIL 2016, I PULLED INTO MY DRIVEWAY AND UPON PRESSING THE BRAKE PEDAL THE CAR SURGED AHEAD AND STRUCK MY GARAGE DOOR, DAMAGING IT. IN THIS INSTANCE I MOVED THE SHIFT LEVER INTO REVERSE TO STOP THE CAR. ON MAY17, 2016 AFTER PICKING UP MY GRANDSON FROM HIS SCHOOL, I EXPERIENCED A SUDDEN UNEXPLAINED ACCELERATION WITH NO DEPRESSION OF THE GAS PEDAL, AND DESPITE DEPRESSING THE BRAKE PEDAL AS HARD AS I COULD, WOULD NOT STOP UNTIL I HIT AND SEVERELY DAMAGED MY CAR AND 2 OTHER CARS, THEN WAS ONLY ABLE TO STOP THE CAR BY MOVING THE SHIFT LEVER INTO PARK. THIS WAS THE 2ND TIME I EXPERIENCED THIS PROBLEM, AND I AM VERY CONCERNED THIS CAN HAPPEN YET AGAIN AND CAUSE EVEN MORE SEVERE DAMAGE AND POSSIBLY INJURY.
