2006 Ford Mustang vehicle speed control problems

“While driving the car goes into limp mode randomly causing the RPM’s to fall. There is no power to get off the road safely and has almost caused an accident numerous times. I have had Diagnostics ran and the mechanic has no clue what’s causing this. Ford forums are full of these mustangs doing this. It is a huge safely risk!!!!”

“On June 18, 2023, my throttle unexpectedly stuck open after intentional acceleration, causing the car to continue to accelerate uncontrollably after releasing the accelerator pedal. The engine continued to increase RPMs and speed. After using all of my leg strength to apply the brakes to fight the uncontrolled acceleration, the throttle unexpectedly eased up and returned to normal. This was the most frightening instance. On two other occasions, I noticed similar uncontrolled acceleration that seemed to correct itself immediately after shifting, where the tachometer approached 5k RPMs. I have not had the vehicle inspected, and there were no warning lamps, or other symptoms prior to this failure.”

“CAR SUDDENLY WENT INTO LIMP MODE, NO REASON. JUST STARTED IT UP ONE DAY AND IT JUST DID NOT WANT TO MOVE. NO ONE KNOWS HOW TO GET IT OUT OF THE MODE. MANY MECHANICS HAVE TRIED WITH NO LUCK. NOW A MECHANIC SAYS I HAVE A FAULTY COMPUTER. 3 YEARS OF IT ACTING THIS WAY.. COMPUTER DIAGNOSIS SHOWED MANY THINGS MESSED UP, EVEN AFTER REPLACING ALL OF THOSE (AND I AM SURE SOME WERE UNEEDED) THE CAR IS STILL IN LIMP MODE, HAS NO POWER AT ALL AND HAS BEEN BASICALLY DOWN FOR 3 YEARS. BEAUTIFUL LAWN ORNAMENT BUT IT BEING ALL I HAVE LEFT OF MY LATE HUSBAND, I'M NOT HAPPY IT JUST SITS THERE. NO MECHANIC WANTS TO EVEN TOUCH IT!”

“TL* TAKATA RECALL. THE CONTACT OWNS A 2006 FORD MUSTANG GT. WHILE ACCELERATING FROM A STOP, THE VEHICLE HESITATED TO PICK UP SPEED AND THEN SURGED AT A HIGH RATE OF SPEED. THE VEHICLE SHIFTED OUT OF GEAR SEVERAL TIMES AND THE CONTACT HAD TO PLACE THE GEAR IN DRIVE 3 TO PREVENT THE FAILURE. IN ADDITION, THE VEHICLE WAS INCLUDED IN NHTSA CAMPAIGN NUMBERS: 15V319000 (AIR BAGS) AND 16V384000 (AIR BAGS). THE CONTACT WAS NOT INFORMED OF THE RECALLS WHEN HE PURCHASED THE VEHICLE. THE DEALER WAS NOT NOTIFIED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS NOT AVAILABLE. PARTS DISTRIBUTION DISCONNECT. VIN TOOL CONFIRMS PARTS NOT AVAILABLE.”

“THE VEHICLE WAS IN MOTION ON A CITY STREET. THE ACCELERATOR WAS BEING DEPRESSED SLIGHTLY TO EITHER MAINTAIN OR SLOWLY ACCELERATE TO A SPEED BETWEEN 30-40 MPH. THE GAS PEDAL THEN PRESSED TO THE FLOOR ON ITS OWN CAUSING THE ENGINE TO REV LOUDLY AND ACCELERATE TO BEYOND 50 MPH ON THE FIRST INCIDENT (NEARLY 70 ON THE SECOND MAJOR INCIDENT). WHEN THE INCIDENTS OCCURRED, THERE WAS NOTHING THAT COULD BE DONE TO STOP THE ACCELERATION. BRAKING ONLY SLOWED THE RATE OF ACCELERATION. PRESSING IN THE CLUTCH WAS INEFFECTIVE. THE INCIDENTS ARE RANDOM. NO IMMEDIATE CAUSE HAS BEEN DETERMINED. BOTH TIMES, THE DRIVER AND FELLOW DRIVERS WERE ENDANGERED BECAUSE OF THE LACK OF CONTROL CAUSED BY THE INCIDENT. THANKFULLY, NO CRASHES HAVE ENSUED YET. NOTHING SHORT OF TURNING OFF THE ENGINE ENTIRELY AFFECTS THE INCIDENT AS IT OCCURS WHICH CAUSES FURTHER ENDANGERMENT. THIS ISSUE HAS OCCURRED ROUGHLY 4 TIMES IN THE SPAN OF ONE MONTH'S TIME. TWO WERE MINOR CASES IN WHICH THE ACCELERATOR RIGHTED ITSELF QUICKLY. THE OTHER TWO WERE MAJOR INCIDENTS RESULTING IN LACK OF SPEED AND CONTROL OF THE VEHICLE. IT IS BELIEVED THE ISSUE IS ARISING FROM THE MECHANICAL NATURE OF THE ACCELERATOR. WHEREAS…”

“PCM MODULE/CRASH DATA REPORT SAYS THAT THE THROTTLE POSITION SENSOR WENT TO 100% WITH ACCELERATOR AT 60% AND THEN THE THROTTLE STAYED WIDE OPEN UNTIL ACCELERATOR PEDAL WAS RELEASED TO APPROX 23% PERCENT. WHY IS THERE A 40% DIFFERENCE IN THE PCM DATA FROM ACCELERATOR PEDAL POSITION TO THE THROTTLE POSITION. AT THE TRIAL A GUY FROM FORD SAID THIS IS NORMAL AND THE THROTTLE IS DESIGNED THIS WAY. MY HUSBAND IS NOW ON HIS WAY TO PRISON. IS THIS TRUE AND CAN ANYONE HELP OR ADVISE US.”
