the following problem happened to me a few years ago (twice within a couple of months) and again, 2 days ago. Each time I was standing at a traffic light when all of a sudden it accelerated at full throttle. I practically stood on the brake pedal, but the car was inching forward, as I put the transmission into park. This was not a subtle situation, it was dangerous. The engine went from idle to screaming within 2 seconds. I ruled out the floor mat as it was in the proper position and snapped into the floor. It did not cause any warning lights to come on. in May, I had the oil changed, at which time they suggested that they clean the throttle body, which they did.They never heard of the above problem.

Was driving my vehicle on the freeway traveling about 70 miles per hour when the vehicle suddenly shifted into first gear. I was able to maintain control and the vehicle shifted back to sixth gear. Issue occurred again within 5 minutes of the first incident and then the vehicle went into "Limp Mode". I was able to drive the vehicle home under this condition. Vehicle check engine light turned on and the code P0720, which is the Output Speed Sensor Circuit. This is the same issue that occurred on 2011-2013 F-150 and Mustang vehicles that currently have a recall for this (Safety Recall 19S07). The same transmissions (6R80) are used in both vehicles, as well as the Powertrain Control Modules, but my vehicle's VIN did not fall under this recall. This is a very dangerous issue that could lead to a deadly accident.

On 5-26-22 i took my mustang to Roush Ford in Hillard Oh. They tested and found out that I needed a lead frame connector. Part # Al327627V $ 226.10. I paid in advance for this part as Roush said they would not order unless I paid in advance. Roush stated they would call when part comes in. I made several attempts to get status of part and all they would say is they were still awaiting. On or about 6-20-23 I called again, At this time they stated the dealership had been sold to Valley ford and still no word on part arrival. I have owned several Fords in my life but after awaiting over 1 yr on a part and car I could not safely have my wife drive I decided to trade it in for another vehicle. I then called Valley to ask for them to credit my card in the amount of the part. They told me that the money went with Roush and they could not return my money?? They suggested I call Roush auto group( Honda ). I made the call to service manager and he said that Roush Ford was no longer in business and they could not refund my monies. In my mind Ford was paid the $226.10 and someone should be able to pay me back. I am asking that The Ford Motor co honor the deal by paying me back. Thanks

THE CAR WOULD LOOSE POWER AND NOT SHIFT PROPERLY. AFTER A YEAR OF TRYING TO DIAGNOSE THE TROUBLE IT WAS THE OUTPUT SPEED SENSOR. FINALLY GOT A TROUBLE CODE. FORD RECALLED THE 2011 & 2012 MUSTANGS BUT NOT MINE. THE OUTPUT SPEED SENSOR IS THE EXACT SAME PART NUMBER FOR THE RECALLED YEARS AND MINE.

TL* THE CONTACT OWNS A 2014 FORD MUSTANG. WHILE DRIVING APPROXIMATELY 10 MPH IN FIRST GEAR, THE GEAR SHIFTER WOULD NOT MOVE TO SECOND GEAR. THE CONTACT HAD TO PULL OVER TO THE SIDE OF THE ROAD TO A COMPLETE STOP. THE CONTACT ATTEMPTED TO DRIVE THE VEHICLE AGAIN, BUT IT WOULD NOT ALLOW HIM TO SWITCH TO SECOND GEAR. THE CONTACT FORCED THE GEAR SHIFTER TO FOURTH GEAR. THE VEHICLE WAS DRIVEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE SKIP SHIFT WAS A STANDARD MANUFACTURER FEATURE IN ALL MANUAL TRANSMISSION VEHICLES, WHICH ALLOWS IT TO SKIP SECOND AND THIRD GEARS FOR LESS FUEL CONSUMPTION. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 30,000.
