2011 Ford Mustang Speed Control & Cruise Problems

WHILE DRIVING MY 2011 FORD MUSTANG (WITH A V6 ENGINE AND AUTOMATIC TRANSMISSION) AT 40MPH ON A LOCAL STREET, I EXPERIENCED THE VEHICLE UNEXPECTEDLY LOSING POWER AND A FAULT LIGHT IN THE FORM OF A WRENCH APPEARING ON THE DASHBOARD. THE ENGINE SPEED DROPPED DOWN TO IDLE AND DID NOT RESPOND TO ANY GAS PEDAL OPERATION. THE CARS ENGINE REMAINED RUNNING, HOWEVER, THE ENGINE RAN ROUGHLY AS EVIDENCE OF IT SHAKING THE ENTIRE CAR. THE INCIDENT PLACED MYSELF AND OTHER DRIVERS AROUND ME IN DANGER, AS I HAD TO MOVE QUICKLY TO GET MY VEHICLE OUT OF THE MOVING TRAFFIC AND INTO A SAFE PLACE OFF THE SIDE OF THE ROAD.

TL* THE CONTACT OWNS A 2011 FORD MUSTANG. WHILE DRIVING 70 MPH WITH THE CRUISE CONTROL ENGAGED, THE VEHICLE STALLED AND THE CHECK ENGINE WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TOWED TO ELKINS FORDLAND (696 BEVERLY PIKE, ELKINS, WV 26241, (304) 636-2222), BUT THEY WERE UNABLE TO DUPLICATE THE FAILURE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS CONTACTED AND DID NOT ASSIST. THE FAILURE MILEAGE WAS 50,000.

TL* THE CONTACT OWNS A 2011 FORD MUSTANG. WHEN THE ACCELERATOR PEDAL WAS DEPRESSED UP TO 40 MPH, THE THROTTLE BECAME STUCK AND THE BRAKES FAILED TO RESPOND WITHOUT WARNING. AS A RESULT, THE CONTACT SHIFTED THE VEHICLE INTO THE NEUTRAL TO STOP. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 43,000.

VEHICLE STUCK ACCELERATOR AT SLOW AND HIGHER SPEEDS!! IT HAPPENED ONCE WHILE I WAS DRIVING IT AND ONCE WHILE MY DAUGHTER WAS DRIVING. THIS COULD EASILY CAUSE SEVERE ACCIDENT. THROTTLE BODY WAS REPLACED BY DEALER. THIS ACCELERATOR PROBLEM HAPPENED AFTER THE THROTTLE BODY WAS REPLACED. BY THE DEALER. I BROUGHT IT BACK TO THE DEALER AFTER THIS INCIDENT AND THEY CALLED ME AND SAID "THEY CAN FIND NOTHING WRONG". I TOLD THEM TO KEEP THE CAR UNTIL THE FIND THE PROBLEM AS THIS OUT OF CONTROL ACCELERATION IS VERY DANGEROUS. *TR

WHILE DRIVING WITH CRUISE CONTROL SET AT 55 MPH, CAR BEGAN TO DECELERATE, YELLOW "WRENCH" ADVISORY LIGHT ILLUMINATED AND ENGINE APPEARED TO BE RUNNING ROUGH. CAR SLOWED TO A STOP AND I PULLED THE CAR OFF THE ROADWAY. I SWITCHED OFF THE IGNITION AND WAITED APPROXIMATELY 30 SECONDS. I RESTARTED THE CAR. THE ADVISORY LIGHT STAYED OFF AND THE ENGINE RAN NORMALLY THEREAFTER. WHEN THE INCIDENT OCCURRED, THE CAR WAS ON A HIGHWAY CURVING TURN TO THE RIGHT. THE INCIDENT OCCURRED COMING OUT OF THE CURVE.

WHILE DRIVING ON THE HIGHWAY THE MOTOR SHUTS OFF. I HAVE TO QUICK PULL OFF THE ROAD, RESTART THE CAR. IT WILL DRIVE BUT AGAIN GET UP TO HIGHWAY SPEED, CAR SHUTS OFF. AFTER ABOUT THE 5TH TIME, FINALLY A CODE COMES ON, P2111 (THROTTLE ACTUATOR CONTROL SYSTEM - STUCK OPEN. VERY DANGEROUS DRIVING ON THE HIGHWAY.

WHILE DRIVING, WITHOUT WARNING, THE VEHICLE'S WRENCH WARNING LIGHT COMES ON AND THE VEHICLE GOES INTO IDLE MODE. THE CAR WILL NOT ACCELERATE AND YOU HAVE TO PULL OVER, TURN THE ENGINE OFF, AND THEN RESTART THE CAR.

TL* THE CONTACT OWNS A 2011 FORD MUSTANG. WHILE DRIVING APPROXIMATELY 65 MPH, THE ACCELERATOR PEDAL WAS DEPRESSED BUT THE VEHICLE FAILED TO ACCELERATE. THE VEHICLE WAS TOWED TO A DEALER WHERE IT WAS DIAGNOSED THAT THE THROTTLE BODY NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED DUE TO PART UNAVAILABILITY. THE CONTACT WAS UNAWARE IF THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS UNKNOWN.

WHILE DRIVING MY 2011 V6 MUSTANG THE CAR WILL COMPLETELY LOOSE POWER. THIS HAS HAPPENED ON THE HIGHWAY AND ON SIDE STREETS. THERE IS NO WARNING. THE WRENCH LIGHT COMES ON AND THE CAR IS FORCED TO IDLE. NO RESPONSE AT ALL TO THROTTLE INPUT. ERROR CODE READ IS P2111 WHICH INDICATES "THROTTLE ACTUATOR "A" CONTROL SYSTEM - STUCK OPEN". IT IS MY UNDERSTANDING THAT THE THROTTLE BODY IN THIS VEHICLE IS THE SAME AS USED IN OTHER FORD VEHICLES. A RECALL HAS BEEN ISSUED FOR THOSE OTHER VEHICLES BUT EVERYONE SUFFERING FROM THIS ON THE V6 MUSTANG IS ON THEIR OWN. THIS CAN BE VERY DANGEROUS FOR PEOPLE ACCELERATING TO MERGE AND VERY DANGEROUS ON THE HIGHWAY TO STOP IN THE MIDDLE OF THE ROAD OR HAVE TO LIMP TO THE SHOULDER THROUGH TRAFFIC AT IDLE. I HAVE ALREADY PAID $300 FOR A FULL THROTTLE BODY SERVICE AND THE SAME THING IS STILL HAPPENING.

ENGINE STALLED WHILE DRIVING SEVERAL TIMES (ONCE ON A CITY STREET AND TWICE ON THE HIGHWAY). ON OTHER OCCASIONS THE CAR WOULD HESITATE TO RESPOND TO THE ACCELERATOR. MECHANIC SCANNED THE COMPUTER AND FOUND CODE P2111 THROTTLE ACTUATOR CONTROL SYSTEM STUCK OPEN, AND DETERMINED THE CAUSE OF THE PROBLEM TO BE THE THROTTLE BODY.

TL* THE CONTACT OWNS A 2011 FORD MUSTANG. THE CONTACT STATED THAT WHILE DRIVING AT 55 MPH, THE VEHICLE FAILED TO ACCELERATE AND STARTED LOSING POWER. THE CONTACT STATED ALSO THAT THE ELECTRONIC THROTTLE BODY WARNING LIGHT ILLUMINATED. THE VEHICLE WAS MERGED TO THE SHOULDER OF THE ROAD BUT STILL FAILED TO ACCELERATE. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE THROTTLE BODY NEEDED TO BE REPLACED HOWEVER, THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 51,800. UPDATED 02/12/16*LJ

IMMEDIATE LOSS OF POWER AND COMPLETE LOSS OF ACCELERATION. THIS HAS OCCURRED IN AN INTERSECTION AND IN THE MIDDLE OF A MULTI-LANE HIGHWAY AT 35 MPH AND 60 MPH AND WHEN EITHER ACCELERATING OR HOLDING AT A STEADY SPEED. THE WRENCH LIGHT COMES ON AND THE VEHICLE IMMEDIATELY LOSES POWER AND DECELERATES REGARDLESS OF SPEED. THE VEHICLE IS INOPERABLE UNTIL IT IS TURNED OFF AND RESTARTED. THE PROBLEM IS RECURRING AND UNPREDICTABLE. BECAUSE THE CODE DISAPPEARS UPON RESTARTING IT CANNOT BE DIAGNOSED. I HAD TO GET A CODE READER TO GET THE CODE WHICH HAD TO BE USED AFTER AN EMERGENCY STOP ALONG THE HIGHWAY. THIS IS DANGEROUS AS THERE IS NO WARNING BEFORE THE LOSS OF POWER. ERROR CODE P2111-THROTTLE ACTUATOR CONTROL SYSTEM STUCK OPEN. THE PROBLEM HAS OCCURRED 10/29/15, 11/16/15, 11/25/15, AND 11/30/15.

TL* THE CONTACT OWNS A 2011 FORD MUSTANG. WHILE DRIVING AT 35 MPH, THE CHECK ENGINE WARNING LIGHT ILLUMINATED AND THE VEHICLE FAILED TO ACCELERATE. IN ADDITION, THE VEHICLE SUDDENLY LOST POWER. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 61,000. THE VIN WAS NOT AVAILABLE.

WHILE DRIVING DOWN THE LEFT LANE OF THE SAWGRASS EXPRESSWAY, A VERY BUSY HIGHWAY BETWEEN FT. LAUDERDALE AND MIAMI, I LOST ALL THROTTLE RESPONSE. THE WRENCH LIGHT CAME ON THE DASHBOARD AND I WENT FROM 60 MPH DOWN TO NOTHING BY THE TIME I WAS OFF TO THE SIDE OF THE ROAD. CARS BEHIND ME WERE OBVIOUSLY BRAKING HARD TO AVOID SMASHING INTO ME. I TURNED THE CAR OFF AND WAS ABOUT TO CALL AAA, BUT THE HEAT INDEX THAT DAY WAS AROUND A MILLION DEGREES SO I TURNED THE CAR BACK ON. THE THROTTLE RESPONSE HAD RETURNED SO I CAUTIOUSLY LIMPED THE CAR BACK HOME IN THE RIGHT HAND LANE THE WHOLE WAY. I THOUGHT IT WAS SOME FREAK COMPUTER GLITCH UNTIL IT HAPPENED AGAIN GOING TO THE STORE THE NEXT DAY. I CALLED THE FORD DEALERSHIP AND BEFORE I EVEN GOT THE PROBLEM OOUT OF MY MOUTH THE SERVICE TECH SAID " IT IS YOUR THROTTLE BODY. WE SEE THIS ALL THE TIME. IT WILL BE ABOUT $800 TO REPAIR". IF THE TECHS ARE AWARE OF THIS PROBLEM AND IT IS ALL OVER THE INTERNET WITH PEOPLE COMPLAINING ABOUT DANGEROUS SITUATIONS THE HAVE BEEN PLACED IN AS A RESULT, AND THERE IS ALREADY A RECALL FOR THE SAME PROBLEM IN OTHER FORD MODELS, THEN WHY HASN'T THE NHTSA DONE ANYTHING TO FORCE FORD TO RECALL FOR THE SAME PROBLEM ON THE MUSTANG? DOES SOMEONE HAVE TO DIE FIRST? HAS SOMEBODY DIED BECAUSE OF THIS?

CAR WOULD NOT RUN > 20 MPH.

6/22/2015: I WAS DRIVING HOME FROM WORK AND MY CAR SUDDENLY TURNED OFF AND THE CHECK ENGINE LIGHT TURNED ON. IT IS VERY SUBTLE WHEN IT HAPPENED; NO JERKY MOVEMENT NOTICED. I REALIZED WHAT HAVE HAPPENED AFTER MY FAILED ATTEMPTS TO ACCELERATE. I WAS ABLE TO USE THE CAR'S MOMENTUM TO MAKE IT TO A PARKING LOT. I STEP OUT AND EXAMINED MY CAR BUT NOTHING WAS OUT OF THE ORDINARY. AFTER 10 MINUTES, I ATTEMPTED TO START IT UP (FIRST ATTEMPT AFTER INCIDENT) AND IT STARTED UP NORMALLY. EVERYTHING FUNCTIONED AS NORMAL AND EVEN THE CHECK ENGINE LIGHT IS GONE. I THOUGHT IT WAS A FLUKE INCIDENT SO I DROVE HOME AND FORGOT ABOUT IT. 6/30/2015: I WAS DRIVING ON THE HIGHWAY AND MY ENGINE CUT OFF AGAIN. I WAS VERY SCARED BECAUSE I WAS ON THE CALIFORNIA 91 FREEWAY AND IT WAS DURING TRAFFIC HOURS. I WAS ABLE TO DRAW EXPERIENCE FROM THE LAST INCIDENT AND CRUISED MY CAR TO THE SIDE OF THE HIGHWAY. AFTER I EXAMINED THE CAR AND ONCE AGAIN WASN'T ABLE TO FIND ANYTHING OUT OF THE ORDINARY. I STARTED IT BACK UP ON THE FIRST ATTEMPT AND THE CAR SEEMED TO BE OPERATING NORMALLY. I WAS ABLE TO MAKE IT HOME SAFELY BUT IT WAS A VERY SCARY DRIVE HOME...I WILL HAVE TO BRING MY CAR TO A DEALER AND GET IT CHECK SOON AND HOPEFULLY THEY WILL HAVE A FIX FOR THIS....UPDATED 09/22/15 *BF UPDATED 11/06/2017*CN

WHILE DRIVING 65 MPH ON THE INTERSTATE MY VEHICLE WENT INTO "LIMP MODE" CAUSING THE VEHICLE TO DRASTICALLY SLOW DOWN AND REQUIRING EVASIVE ACTION TO GET TO THE SHOULDER DURING HEAVY TRAFFIC. THIS HAS NEVER HAPPENED BEFORE AND I WENT TO THE DEALERSHIP AND WAS ADVISED THAT THE FAULT CODE WAS "P21111 THOTTLE ACTUATOR CONTROL SYSTEM STUCK OPEN".

MY 2011 V6 FORD MUSTANG HAS NOW STALLED SEVERAL TIMES GOING DOWN THE ROAD. HAS HAPPENED AT BOTH HIGH AND SLOWER SPEEDS. AFTER PULLING OVER AND WAITING A FEW MINUTES, CAR STARTS AND RUNS OKAY UNTIL THE NEXT UNEXPECTED STALL. REPAIR SHOP REVEALED NO CODES. VERY DANGEROUS PROBLEM!

VEHICLE MOTOR ACCELERATES WHILE SETTING STILL AT HIGH RATE. HAD TO PUT VEHICLE IN NEUTRAL AND CUT IGNITION KEY OFF. IF I HADN'T HAD MY FOOT ON BRAKE WOULD HAVE RAN INTO BUILDING. *TR
