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.

The contact owns a 2014 Ford Mustang. The contact stated that while driving approximately 35-70 MPH, the vehicle inadvertently downshifted to first gear.

The vehicle was towed to the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was contacted but no assistance was provided. The failure mileage was approximately 80,000.

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

While driving the clutch pedal will stick to the floor after shifting gears. You can pull the pedal up manually and it will functioning properly for a while but will repeat sticking to the floor. May happen once a day, once a week or more often. Ambient temperature has no affect to the problem. Car currently has 15,000 miles on it

THE 6 SPEED MANUAL TRANSMISSION GRINDS AND/OR LOCKS OUT OF GEAR WHEN SHIFTING FROM 1ST TO 2ND GEAR. THE CAR BUCKS AND SURGES, WORSE WHEN GOING DOWNHILL. IT MAKES A KNOCKING NOISE WHEN THERE IS A TORQUE CHANGE.

PURCHASED CAR NEW IN 2014 AND NOTICED VIBRATION IN TRANSMISSION UPON DECELERATION. I WAS INFORMED BY THE DEALER THAT THIS WAS A KNOWN ISSUE BUT IT WAS NOT GOING TO CAUSE AND LONG TERM ISSUES, AFTER THE WARRANTY HAD EXPIRED I STARTED EXPERIENCING SHIFTING ISSUES INTERMITENTLY, I HAVE CONTACTED THE DEALER ON SEVERAL OCCASIONS AS THIS HAS PROGESSIVLEY GOTTEN WORSE TO CHECK FOR KNOWN ISSUES OR IF THEY WERE GOING TO DO ANYTHING ABOUT IT. NOW WITH 85000 MILES THE CAR IS VIRTUALLY UNDRIVEABLE AND WONT SHIFT INTO SECOND GEAR AND STILL HAS THE VIBRATION. FORD CUSTOMER SERVICE SAYS THERE IS NOTHING THEY CAN DO AND STILL SAYS THEY DO NOT KNOW OF ANY ISSUES WITH THIS TRANSMISSION EVEN THOUGH THERE HAS BEEN A CLASS ACTION SUIT STARTED.

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.

WHILE DRIVING THE MUSTANG (WHICH IS A MANUAL TRANSMISSION) I NOTICED THAT THE SPEED OF THE CAR DOESN'T DECELERATE WHEN I TAKE MY FOOT OFF THE GAS PEDAL.

ALSO, WHILE THE CAR IS IN GEAR, THE ENGINE FIGHTS TO SLOW DOWN WHILE DEPRESSING THE BRAKE PEDAL. THIS DOESN'T HAPPEN EVERY TIME BUT WHEN IT OCCURS WHILE IN A PARKING LOT WITH PEOPLE AROUND IT BECOMES A SERIOUS SAFETY ISSUE. *TR
