THROTTLE BODY MALFUNCTION. ENGINE REVES UP WHILE PLACING THE CAR IN DRIVE OR REVERSE WITHOUT TOUCHING THE GAS PEDAL, UP TO 1.5 ON THE RPM'S ON THE SPEEDOMETER. THIS IS VERY SCARY, A CHILD CROSSED IN FRONT OF ME WHILE I WAS WAITING AT A STOP SIGN. FOOT WAS ON THE BRAKE BUT ALL OF A SUDDEN IT JUST REVED UP. IT LUNGED FORWARD AND I HD TO REALLY PUT THAT BREAK ON. SCARED ME AND THE CHILD TO.

WHILE STUCK IN RUSH HOUR TRAFFIC, CAR WAS AT A COMPLETE STOP AT A RED LIGHT. WHEN TRYING TO LET OFF THE GAS, THE CAR LURCHED FORWARD ALMOST PLOWING INTO THE CAR IN FRONT OF ME. THIS OCCURRED ON 06/20/2012. DURING SUMMER 2011, THIS SAME TYPE OF BEHAVIOR OCCURRED 4 DIFFERENT TIMES. THE ENTIRE PROCESS BEGINS WITH THE CAR BEING AT A COMPLETE STOP, THEN WHEN LETTING OFF THE GAS, THE CAR'S ENGINE REV'S AND THE CAR LURCHES FORWARD REQUIRING THE DRIVER TO SLAM ON THE BREAKS FROM HITTING OTHER DRIVERS/PEDESTRIANS. WHEN THE VEHICLE DOES THIS LURCHING FORWARD MOTION, SEVERAL RED LIGHTS COME ON THE INSTRUMENT PANEL AND ALSO THE COMPUTER READS AN ERROR OF "FAILSAFE ENGINE MODE". POWER STEERING, POWER BRAKES HAVE BEEN LOST WHILE THIS EVENT OCCURS AS WELL. SEEMS AS IF IT COULD BE AFFECTED BY WARMER WEATHER BECAUSE I HAVE OWNED THE VEHICLE TWO YEARS AND...

TL* THE CONTACT OWNS A 2005 FORD FIVE HUNDRED. THE CONTACT STATED THAT WHILE DRIVING 60 MPH, THE FAIL SAFE MODE ACTIVATED, CAUSING THE VEHICLE TO STALL. THE VEHICLE WAS MERGED TO THE SHOULDER, TURNED OFF AND THEN RESTARTED AFTER SEVERAL MINUTES, AS IT RESUMED NORMAL OPERATION. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE CONTACT WAS AWAITING A FULL DIAGNOSIS OF THE FAILURE. THE MANUFACTURER WAS NOTIFIED WHO ADVISED THAT THERE WERE NO RECALLS FOR THE VEHICLE AND OFFERED NO OTHER ASSISTANCE. THE FAILURE MILEAGE WAS 126,000.

WHEN YOU ARE DRIVING THE VEHICLE WILL STOP ACCELERATING AND A FAIL SAFETY MODE LIGHT COMES ON, IF YOU PULL OVER AND RESTART IT, IT WILL RESTART AND HAPPENS A FEW MINUTES LATER. *TR

ENGINE RANDOMLY ACCELERATES DURING HOT WEATHER AND COLD STARTS. TOOK TO FORD GARAGE WHO REPORTED DEFECTIVE SPARK PLUG WIRE. DID NOT FIX PROBLEM WHICH HAS RECURRED. GT ERROR CODE FROM PARTS STORE. FORD DEALER DECLINED EXISTENCE OF SUCH CODE. ONLINE SEARCH REVEALED REPORTS OF THROTTLE BODY MALFUNCTION WHICH CAN BE TREATED WITH FUEL ADDITIVE. SEEMED TO STOP IT FOR A WHILE BUT HAS RECURRED ON SEVERAL OCCASIONS. ANOTHER NON DEALER REPAIR SHOP COULD NOT FIND DEFECT. PROBLEM HAS AGAIN RECURRED WITH FIRST HOT(OVER 90) WEATHER. *TR

MY WIFE, SON AND I WERE DRIVING. THE VEHICLE HAD RANDOM ACCELERATION WHILE AT FULL STOPPED. ABOUT 10 MINUTES LATER AFTER A FULL STOP THE VEHICLE HAD ANOTHER ACCELERATION WHILE FOOT ON BRAKE AND THE VEHICLE STALLED OUT. ONCE STALLED OUT THE COMPUTER DISPLAYED THE FOLLOWING ERROR "FAIL SAFE ENGINE". AFTER DOING AN ONLINE REVIEW I NOTICED THAT MANY OTHER FORD FIVE HUNDRED OWNERS HAVING THE SAME ISSUE AND SEEMS TO BE CAUSED BY "THROTTLE BODY". PLEASE NOTE THAT WHENEVER THE VEHICLE IS ON PARK AND PUT INTO REVERSE, THE HIGHER ACCELERATION TAKES PLACE. I ALWAYS HAVE TO BE EXTRA CAREFUL. I HAVE TO BE EXTRA CAREFUL WHILE DRIVING AS I AM AFRAID FOR ACCELERATION AND STALLING OUT IN THE MIDDLE OF THE ROAD. *TR
