What 1,717 owners told NHTSA about the 2012 Ford F-150 Supercab

FOR THE FOURTH TIME, MY 2012 FORD F150 ECOBOOSTED ENGINE STALLED OR SHUTTERED WHEN HAULING A LOAD (TRAILER OR HEAVY BED LOAD) IN A HIGH HUMIDITY ENVIRONMENT. I WAS PULLING A U-HAUL TRAILER BEHIND MY TRUCK AND IT WAS RAINING HEAVILY. WHEN I PUNCHED THE ACCELERATOR TO PASS A SLOWER VEHICLE, THE ENGINE STALLED, SPUTTERED, AND NEARLY SHUT DOWN. THE "CHECK ENGINE" LIGHT CAME ON FOR ABOUT A MINUTE, THEN TURNED OFF ONCE THE ENGINE HAD CLEARED WHAT FELT LIKE CONDENSATION, AND RETURNED TO NORMAL OPERATING MODE. WHEN I TOOK THE VEHICLE TO THE DEALERSHIP TO COMPLAIN (FOR THE 4TH TIME), THEY TOLD ME THAT THEY WERE OF AWARE OF A DESIGN PROBLEM WITH THE INTERCOOLER ON 2011-2013 TURBOCHARGED VEHICLES, BUT SINCE THEY COULD NOT VERIFY THE DEFECT "CODE," FORD WOULD NOT REIMBURSE THEM FOR THE SERVICE FIX. THIS IS CLEARLY A SAFETY AND ENVIRONMENTAL ISSUE AS THE SERVICE BULLETIN THAT FORD ISSUED TO CORRECT THE PROBLEM, REQUIRES REPLACEMENT OF THE CATALYTIC CONVERTER AS WELL. FRUSTRATED! *TR

DRIVING HOME FROM VACATION WE HAD STOPPED AND WERE GETTING BACK ONTO HIGHWAY , IT HAD BEEN RAINING ALL THE WAY AND WHEN WERE MERGING BACK ONTO HIGHWAY I ACCELERATED QUICKLY THE TRUCK STARTED SHAKING LOST POWER I LIFTED OFF ACCELERATOR UNTIL THE SHAKING HAD QUIT AND THEN EASED BACK IN AND WAS ABLE TO DRIVE THE REST OF THE WAY HOME. THE CHECK ENGINE LIGHT CAME ON DEALER SHOWED IT AS A MISFIRE. THE CURRENT FIX FOR THIS IS TO COVER THE FIRST 6 TO 8 INCHES OF THE INTERCOOLER. *TR..UPDATED 09-24-14 *BF

WHILE TRYING TO PASS ANOTHER VEHICLE DURING WET WEATHER , MY VEHICLE WOULD LOOSE ENGINE POWER AT A CRITICAL MOMENT DURING PASSING. FORD DEALER COULD FIND NO PROBLEM. LOSS OF POWER HAPPENED MORE THAN ONE TIME WHILE PASSING. AFTER ABOUT ONE YEAR OF SERVICE I TRADED VEHICLE OFF....NOT LIKING THE PASSING PERFORMANCE DURING WET WEATHER. THEN FOUND OUT THAT THIS IS A PROBLEM WITH MANY F150 ECOBOOST ENGINES. I BELIEVE THIS IS A SERIOUS ISSUE.[XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

DRIVING DOWN THE INTERSTATE DURING WET CONDITIONS MY 2012 FORD F150 ECOBOOST STARTED TO STUMBLE AND LOOSE POWER DRASTICALLY WHILE PULLING A TRAILER. THE TRUCK WOULD ONLY DO 30 MPH AS IT SHOOK AND STUMBLED DOWN THE INTERSTATE. THIS POWER LOSS MADE IT REALLY DANGEROUS TO GET OFF THE ROAD SAFELY WITHOUT OTHER CARS AND TRUCKS BEING AFFECTED. THE ONLY WAY TO RESET THE TRUCK WAS TO SHUT THE ENGINE OFF AND RESTART IT. THIS HAS HAPPENED TWICE TO ME DURING WET RAINY CONDITIONS. THIS ISSUE REALLY CONCERNS ME FROM THE SAFETY OF MY WELL BEING AND OTHER FELLOW DRIVERS. FORD NEEDS TO TAKE ACTION IN FIXING THIS PROBLEM WITH THE F150 ECOBOOST TRUCKS. *TR

WAS TRAVELING UP THE ROADWAY ON 6/1/14 IN OUR 2010 F-150 XLT AND WENT TO MAKE A TURN INTO AN INTERSECTION. THE VEHICLE STALLED AND WAS RENDERED USELESS IN THE MIDDLE OF THE INTERSECTION. THE VEHICLE LOST COMPLETE POWER, STEERING CAPABILITY, AND BRAKING WAS DIMINISHED TREMENDOUSLY. WE WERE STALLED IN AN INTERSECTION WITH CROSS TRAFFIC APPROACHING AT 55MPH. WITH LITTLE TIME DUE TO ONCOMING VEHICLES, WAS ABLE TO IMMEDIATELY RESTART THE ENGINE AND PROCEED, BEFORE ONCOMING VEHICLES APPROACHED US IN THE INTERSECTION. NOT VERY SAFE BEING THAT MY ENTIRE FAMILY WAS IN THE TRUCK. FORD HAS ISSUED A SERVICE BULLETIN ABOUT THE ISSUE WITH THE VAPOR CANISTER PURGE VALVE AND ITS NEEDING TO BE REPLACED. HOWEVER, I BELIEVE THIS IS A SERIOUS SAFETY ISSUE BEING THAT THE VEHICLE STALLS WHEN REDUCING SPEED (SUCH AS TURNING INTO INTERSECTIONS WITH OTHER ONCOMING TRAFFIC COMING AT YOU). THERE IS NO RECALL IN LIEU OF THIS POTENTIALLY DANGEROUS SITUATION THEY ARE CAUSING. ADDITIONALLY, THIS PROBLEM WITH THE CANISTER CAUSES A TREMENDOUS VACUUM ON THE FUEL TANK, SO MUCH THAT IT DAMAGES INTERNAL COMPONENTS AND HAS RAISED QUESTIONS ABOUT WHETHER IT IS AFFECTING THE STABILITY OF THE ACTUAL TANK ITSELF. WHEN YOU GO TO FUEL THE VEHICLE, THERE IS SO MUCH OF A VACUUM THAT YOU HEAR IT RELEASE THE PRESSURE WHEN INSERTING THE NOZZLE. IMMEDIATELY AFTER FUELING, THE VEHICLE WILL NOT START FOR SEVERAL MINUTES. THIS ISSUE NEEDS TO BE CORRECTED BEFORE SOMEONE IS SERIOUSLY INJURED OR KILLED DUE TO THEIR VEHICLE SITTING IN THE MIDDLE OF A ROADWAY AND BEING HIT BY ONCOMING TRAFFIC. *JS

MY TWO CHILDREN AND I WERE DRIVING UP HWY 75 NORTH FROM MACON WHEN WE ACCELERATED TO THE NEXT LANE. THE SPEED LIMIT IS 70 SO WE WERE JUST GOING TO PASS IN AT A NORMAL RATE WHEN THE ENGINE JUST QUITS AND THE WHOLE CAR STARTS TO SHUDDER. NOW I HAVE HAD THIS HAPPEN AT 19,000 MILES AND TOOK IT IN TO THE DEALERSHIP. THIS WAS ONLY ABOUT TWO MONTHS AGO. WENT IN TODAY BEFORE I READ ALL THE COMPLAINTS ABOUT THIS 3.5 ECO BOOST ENGINE AND THE SIMILAR PROBLEMS I EXPERIENCED. IT WAS RAINING ON WHEN WE HAD THIS HAPPEN BUT IT OCCURRED BEFORE WITH NO RAIN. AS THE TRUCK STOPPED AND SHUDDERED WE WERE FINALLY ABLE TO GET TO SIDE OF THE ROAD AND DID NOT GET HIT BY ONCOMING TRAFFIC. THERE ARE SIX LANES OF TRAFFIC IN THIS AREA. SURPRISED TODAY WHEN I WENT TO THE DEALERSHIP AND TOLD THEM WHAT WAS HAPPENING AND THEY DIDN'T EVEN KNOW OF THE PROBLEMS OR HAVE EVER HEARD OF IT. ????? SO BASED ON WHAT I HAVE READ I CALLED BACK ONLY TO FIND OUT THEY HAVE HAD ISSUES. *TR

I HAD BEEN TRAVELING ON THE INTERSTATE IN SOUTH FLORIDA ON A CLEAR AND SUNNY DAY WHEN I SLOWED FOR TOLLS. AS I TRIED TO SPEED BACK UP, THE TRUCK STUMBLED AND ACTED LIKE IT WAS LOSING POWER. THEN, THE CHECK ENGINE LIGHT CAME ON. THE TRUCK HAS BEEN TO THE DEALERSHIP ON 10/09/13 AT 22,489 FOR THE SAME ISSUE AND THE FOLLOWING: SAWGRASS FORD- ?CHECK ENGINE LIGHT?- INSTALLED LOWER AIR DEFLECTOR PER TSB 13-8-1 08/05/13 (3.5L GTDI?INTERMITTENT STUMBLE/MISFIRE ON ACCELERATION FROM HIGHWAY CRUISE IN HUMID OR DAMP CONDITIONS WITH POSSIBLE DTC P0304, P0305, P0306, OR P0430). THE TRUCK IS DANGEROUS TO DRIVE IF YOU ARE TRYING TO ACCELERATE INTO TRAFFIC OR TRYING TO PASS SOMEONE. *TR

TRAVELING DOWN THE ROAD. GOT UP TO 55 TO 60 MPH LOST POWER TRANSMISSION STARED JERKING. POWER CAUGHT BACK UP AND LUNGED FORWARD. AT TIMES THE ENGINE STALLS AND CATCHES BACK UP.

FORD F150, 3.5L ECOBOOST ENGINE- WHILE DRIVING IN RAIN, VEHICLE HESITATED AND MISFIRED, WITH AN ASSOCIATED CHECK ENGINE LIGHT ON SOME OCCASIONS AND NOT ON OTHERS. SEEMED TO HAPPEN AFTER CRUISING AND ATTEMPTING TO PASS ANOTHER VEHICLE. WAS UNABLE TO ACCELERATE AND CONTINUED TO SLOW TO 50MPH. HAD TO EASE ON THE THROTTLE TO SLOWLY ACCELERATED AFTER THE CONDITION CLEARED. VEHICLE IN THE SHOP 4 TIMES FOR UPDATES, 3 FOR CHANGES TO THE INTERCOOLER AND THE LAST WAS FOR A CHANGE OF THE CATALYTIC CONVERTER. *TR

I WAS TRAVELLING ON A 4-LANE, 65MPH HIGHWAY WHEN I FLOORED THE GAS PEDAL. THE TRUCK FAILED TO ACCELERATE AS IT SHOULD HAVE. INSTEAD, IT ACTED AS IF IT WAS COASTING. THERE WAS NO POWER FOR SEVERAL SECONDS EVEN WHEN I MOVED THE GAS PEDAL TO DIFFERENT POSITIONS. WHEN THE TRUCK FINALLY SEEMED TO RESUME POWER, IT STARTED TO SHAKE VIOLENTLY. THE SHOCKED PASSENGER AND I LOOKED AT EACH OTHER, THEN I CHECKED TO SEE IF THERE WERE PARTS STREWN ON THE ROAD BEHIND ME. SUDDENLY, IT SMOOTHED OUT AND THERE WERE NO MORE ISSUES ON THAT TRIP. I HAD BEEN DRIVING THAT TRUCK FOR ABOUT 10 HOURS WITH VARIOUS FORMS OF PRECIPITATION AT THE TIME. THIS WAS DECEMBER 21, 2013. THE SECOND INCIDENT WAS ON DECEMBER 28, 2013. WEATHER CONDITIONS WERE SUNNY AND DRY. I HAD BEEN DRIVING ABOUT 50 MINUTES. I FLOORED THE GAS PEDAL AGAIN TO OVERTAKE A VEHICLE AND WAS BARELY ABLE TO OVERTAKE DUE TO NO POWER. AGAIN, I WORKED THE THROTTLE TO NO AVAIL. THE TRUCK FINALLY RECOVERED BUT STARTED SHAKING VIOLENTLY AGAIN. AS BEFORE, IT SMOOTHED OUT. I TOOK MY TRUCK TO A LOCAL FORD DEALERSHIP WHERE THEY TOLD ME IT WAS SHOWING NO CODES AND THAT THEIR TECHS COULD NOT REPRODUCE THE SYMPTOMS I HAD MENTIONED. I CHECKED ON NHTSA WEBSITE AND FOUND THIS ISSUE IS UNDER INVESTIGATION. I DO NOT AGREE WITH THE SERVICE BULLETINS. MY THEORY IS THAT THERE IS A COMPUTER PROGRAMMING PROBLEM SPECIFIC TO THIS DIRECT-INJECTION, TURBO GASOLINE ENGINE. I PLAN ON TRADING FOR SOMETHING OTHER THAN AN ECOBOOST ENGINE, AS THIS PROBLEM IS DANGEROUS. *TR

NHTSA ODI 10560531

I HAVE A 2012 FORD F-150 WITH THE ECOBOOST ENGINE. WHILE SLOWLY ACCELERATING AT HIGHER SPEEDS (GENERALLY AROUND 50 TO 70 MPH), THE ENGINE MISSES TERRIBLY ON MULTIPLE CYLINDERS AND THE TRUCK JERKS AND LUNGES VIOLENTLY ALL WHILE LOSING POWER AND SPEED. IT HAPPENS FREQUENTLY, BUT MOST OFTEN WHEN SLOWLY ACCELERATING TO MAINTAIN SPEED UP A HILL OR PASS ANOTHER VEHICLE. THE LOSS OF POWER IS EXTREMELY DANGEROUS, ESPECIALLY WHILE PASSING OTHER VEHICLES ON A HIGHWAY. *TR

I WAS ON A HIGHWAY GOING 65 MPH, THE CONDITIONS WERE DRIZZLE/VERY HUMID, ROUGHLY 90 DEGREES OUTSIDE. THERE WAS A SLOW CAR IN FRONT OF ME SO I GOT IN THE ON COMING TRAFFICS LANE TO PASS THE CAR, BUT WHEN I STOMPED ON THE GAS PEDAL THERE WAS NO RESPONSE. MY TRUCK WOULDN'T ACCELERATE SO I PUSHED IT A FEW MORE TIMES AND STILL NOTHING. THERE WAS A CAR COMING AND I ALMOST GOT HIT HEAD ON BECAUSE OF THIS INCIDENT AND PROBABLY WOULD'VE BEEN BADLY INJURED HAD I NOT GOTTEN BACK IN MY LANE JUST BEFORE THE CAR PASSED. THE ENGINE RETURNED TO NORMAL AFTER ABOUT 20 SECONDS AND I WAS ABLE TO ACCELERATE AND FINALLY GET AROUND THE CAR. THIS IS ONLY 1 OF THE 5 TIMES IT HAS HAPPENED IN THIS SPECIFIC VEHICLE, ITS HAPPENED TO ME THREE TIMES, AND TWICE WHEN I'VE LOANED THE TRUCK TO MY FATHER. IT ONLY HAPPENS IN HUMID OR RAINY CONDITIONS AND I'M GUESSING HAS SOMETHING TO DO WITH THE INTERCOOLER. BUT I'M NOT AN AUTO GUY SO I WOULDN'T KNOW. I CALLED FORD CORPORATE AND THEY SAID GO TO THE DEALER, THE DEALER DIDN'T SEE ANY CODES THAT WERE THROWN DURING THESE INCIDENTS SO THEY SAID THEY COULD NOT HELP ME. IT WAS [XXX], AND FORD NEEDS TO STEP UP AND HELP US WHO HAVE DEFECTED ECOBOOST ENGINES. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

I WAS ON A TRIP FROM OKLAHOMA TO FLORIDA. I STOPPED FOR GAS IN LOUISIANA. WHEN I GOT ON TO THE ON RAMP TO RETURN TO THE INTERSTATE I FLOORED THE GAS PEDAL TO GET IN FRONT OF A SEMI TRUCK, AND IT LOST ALL POWER ALMOST BEING HIT BY SEMI TRUCK. AFTER MY TRIP I TOOK MY PICKUP TRUCK TO MY FORD DEALER TO HAVE IT CHECKED OUT.THEY TOLD ME THEY CAN NOT FIND ANYTHING WRONG WITH IT. THIS IS A VERY DANGEROUS PROBLEM THAT NEEDS TO BE FIXED. ME AND MY WIFE COULD HAVE BEEN KILLED IF THE SEMI TRUCK DID NOT HAVE ROOM TO MOVE OVER TO MISS US. *TR

ON 2 SEPARATE OCCASIONS, APPROXIMATELY 3 MONTHS APART WHILE IN HARD ACCELERATION ATTEMPTING TO MERGE ON AN INTERSTATE ON-RAMP, VEHICLE BEGAN TO SHUDDER VIOLENTLY AND LOSE POWER. IN FIRST INSTANCE, I WAS ABLE TO MERGE IN THE LEFT LANE AND LET OFF THE ACCELERATOR. AS VEHICLE COASTED, THE SHUDDER SUBSIDED AND WITHIN 1 MINUTE STOPPED ALL TOGETHER. IN THE SECOND INSTANCE, WHEN THE VEHICLE LOST POWER, TRAFFIC CONDITIONS WOULD NOT ALLOW ME TO MERGE AND I WAS FORCED TO COAST ALONG THE SHOULDER OF THE ROAD UNTIL THE SHUDDER SUBSIDED AND POWER WAS RESUMED. IN NEITHER SITUATION, DID THE VEHICLE GO INTO SAFE MODE OR THE CHECK ENGINE LIGHT APPEAR. VEHICLE SIMPLY RESUMED NORMAL OPERATION. *TR

I ONLY JUST LEARNED OF YOUR INVESTIGATION SO MY MEMORY ON EXACT DATES AND MILEAGE MAY BE OFF BY A FEW WEEKS. I DID TAKE MY TRUCK TO THE FORD DEALER TO REPORT MY INCIDENT SO THEY SHOULD SHOULD HAVE A RECORD OF THIS AND THE WORK THEY PERFORMED (BAIERL FORD, ZELIENOPLE, PA 16063). MY 2012 F150 WITH THE 3.5L ECOBOOST WAS ABOUT 6 MONTHS OLD AT THE TIME. I WAS PASSING A COAL TRUCK UPHILL ON A 10% GRADE. I WAS NOT TOWING, NOR DID I HAVE A LOAD IN THE BED. HE WAS GOING ABOUT 30 MPH. I EASED OUT AND GOT ALONG SIDE RUNNING NOW AT ABOUT 50-55, THEN 'PUNCHED' THE THROTTLE TO COMPLETE THE PASS. THAT DID NOT TURN OUT WELL. THE ENGINE CUT OUT EXACTLY LIKE A REVERSE LIMITER ON AN ATV AND THE CHECK ENGINE LIGHT CAME ON. I BARELY WAS ABLE TO COMPLETE THE PASS, AND WAS 'PUSHED' UP THE HILL BY THE COAL TRUCK, ENGINE RUNNING IN THAT CUT-OUT MODE ALL THE WAY. GOT OVER THE TOP AND IT CONTINUED TO RUN LIKE THIS DOWN THE OTHER SIDE. AFTER ABOUT 6 MILES, IT WENT BACK TO NORMAL AND THE CHECK ENGINE LIGHT WENT OUT. TOOK IT TO MY DEALER NOT TOO LONG AFTER. THEY INSTALLED SOMETHING - SINCE IT WAS WARRANTY WORK I WASN'T GIVEN THE PAPERWORK AND SIMPLY DON'T RECALL WHAT THEY DID. APPARENTLY THERE WAS A TSB ON THE PROBLEM THOUGH. I HAVE NOT HAD A REPEAT IN THE 6 MONTHS SINCE, ALTHOUGH I DO DRIVE DIFFERENTLY NOW, HAVING EXPERIENCED THAT EPISODE. THAT EVENT SEVERELY COMPROMISED MY CONFIDENCE IN THIS ENGINE. SINCE THEN I HAVE BEEN VERY ADVERSE TO PASSING ON TWO LANE ROADS AND HAVE DELAYED TOWING SEVERAL TIMES FOR FEAR THIS WOULD HAPPEN AGAIN POTENTIALLY CREATING A DEADLY SITUATION. *TR

I HAD READ ABOUT THIS ISSUE BUT THOUGHT I WAS ONE OF THE LUCKY ONES THAT DIDN'T HAVE A ISSUE. HOWEVER AT ABOUT 11,500 MILES DRIVING IN A RAINY HUMID DAY ON THE HIGHWAY I GOT IN A SPOT WHERE I HAD A RIG GOING ABOUT 30MPH AND I WAS DOING ABOUT 60MPH HAVING MORE THAN ENOUGH TIME TO PASS SAFELY BEFORE THE OTHER RIG COMING UP IN THE PASSING LANE I DECIDED TO GO AROUND.. AS SOON AS I PUSHED THE PEDAL TO THE FLOOR AND GOT IN THE PASSING LANE THE TRUCK LOST POWER,,, SHUDDERED BADLY AND I ALMOST COULDN'T GET AROUND THE RIG THAT WAS ONLY DOING 30! AFTER GETTING BY I DECIDED TO TRY TO GET OFF THE ROAD AND AGAIN I WAS SUCCESSFUL BUT NOT WITHOUT THE ANXIETY ON THINKING THE RIG COMING UP WOULD NOT BE ABLE TO SLOW DOWN ENOUGH TO ALLOW ME TO GET OFF THE ROAD WITHOUT PUSHING ME OFF. SO FAR THERE HAVE BEEN NO KNOWN ACCIDENTS BUT AGAIN IF THE CONDITIONS ARE RIGHT FOR AN ACCIDENT TO HAPPEN COULD BE AS SIMPLE AS PASSING ON A FOGGY NIGHT AND THE PERSON COMING UP ON YOU AT 70 NEVER SAW THE F150 ECOBOOST SITTING IN THE PASSING LANE DOING 45 TRYING TO GET IT OFF THE SIDE OF THE ROAD PASSING AT THE TOP OF A HILL WITH NOWHERE TO PULL OFF TO THE RIGHT AS GOING DOWN THE HILL WITH A 70 MPH TRACTOR TRAILER DRIVER DOING HIS BEST TO SHUT DOWN HIS RIG TRYING TO AVOID A JACK KNIFE DUE TO A F150 ECOBOOST DOING 40 MPH WITH NO WHERE TO PULL OFF! SO ANY OF YOU THAT THINK THIS ISN'T A BIG PROBLEM WAITING TO HAPPEN THEN I SUGGEST ONE THING.... HOPE,,, PRAY,,,, THAT YOU NEVER COME UP ON A ECOBOOST PASSING A RIG AND FIND YOURSELF BETWEEN A F150 LOSING 30 MPH AND TRYING TO GET OFF THE ROAD, THEN YOU,, FOLLOWED BY A RIG DOING 70 MPH ON YOUR BUMPER IN THE PASSING LANE!!! *TR

WE WERE RETURNING FROM ARKANSAS IN OUR F150 WITH THE ECOBOOST ENGINE IN RAIN/HEAVY MIST. WE WERE ON THE INTERSTATE FOR A LONG PERIOD OF TIME AND WHEN I WENT TO PASS A SLOWER VEHICLE THE TRUCK JUST SHOOK AND WOULDN'T ACCELERATE. IT HAPPENED AGAIN 1.5 HOURS LATER IN THE SAME CONDITIONS, TRUCK WOULD NOT ACCEPT ANYTHING BEYOND 3/8 THROTTLE. THIS HAPPENED BEFORE WHEN WE WERE IN THE RAIN (COMING FROM ARKANSAS) WITH THE EXACT SAME CONDITIONS (YEAR AGO). I HAVEN'T TAKEN THE TRUCK TO THE DEALER AS FROM READING SEVERAL PLACES THERE ISN'T A TRUE FIX AT THIS POINT. SOME PEOPLE ARE DRILLING HOLES IN THEIR INTERCOOLERS TRYING TO DRAIN THE WATER THAT APPEARS TO BE THE ISSUE. *TR

I PURCHASED MY F-150 ECOBOOST, ON JULY 28, 2012. ALMOST IMMEDIATELY AFTER PURCHASING IT, I HAVE HAD ISSUES WITH THE ENGINE. OFTEN WHEN IT RAINS, THE TRUCK WILL NOT START OR WHEN IT DOES START, IT REFUSES TO GO OR WHEN IT IS GOING, IT WILL NOT ACCELERATE. WHEN I ATTEMPT TO PASS A SLOW VEHICLE, THERE IS NO POWER. THE ENGINE BOGGS DOWN, TO AN IDLE. THE TRUCK HAS LEFT ME STRANDED NUMEROUS TIMES. I TOOK MY FAMILY ON A TRIP TO MIAMI, FLORIDA, DURING THE CHRISTMAS HOLIDAY. ON THE OPEN ROAD THE MOTOR QUIT. I WAS ABLE TO LIMP IT INTO A FORD DEALER, WHO HAD TO PERFORM EXTENSIVE ENGINE REPAIRS IN ABLE TO GET THE TRUCK RUNNING AGAIN. WHILE I WAS DRIVING IT BACK TO TENNESSEE, AFTER 3 WEEKS OF REPAIRS, IT HAPPENED SEVERAL MORE TIMES. WHEN I ATTEMPT TO PASS SLOWER VEHICLES, I TRY TO ACCELERATE AND THERE IS NO POWER. IT IS DANGEROUS, PARTICULAR WHEN TRAVELING ON 2 LANE COUNTRY ROADS WITH HILLS. OFTEN, WHEN I PARK AND EXIT THE TRUCK, THERE IS A STRONG ODOR OF GAS COMING FROM SOMEWHERE UNDER THE HOOD OF THE VEHICLE. THIS IS A FIRE HAZARD. ON 2 OCCASIONS, THE DRIVER'S SEAT HAS COME UNATTACHED FROM THE FLOOR OF THE TRUCK. THIS MORNING, I WENT TO TAKE MY CHILDREN TO SCHOOL I WAS DRIVING AND HEARD/FELT THUMPING AND THE SEAT FELL BACK, I WAS NEARLY LAYING ON MY BACK, WHILE DRIVING. THIS HAS HAPPENED TWICE. THIS IS DANGEROUS AND SCARY, WHEN IT HAPPENS WHILE DRIVING DOWN THE ROAD. THE FORD CUSTOMER CARE REPRESENTATIVE WAS VERY FLIPPED AND SEEMED TO BE MORE CONCERNED WITH ENSURING THAT I UNDERSTOOD THE TERMS OF THE WARRANTY THAN THE SAFETY OF MY VEHICLE. I WAS INSULTED AND HUMILIATED, FOR SUGGESTING THEY PROVIDE ME WITH SOMETHING TO DRIVE WHILE THEY CORRECTED THE PROBLEM. THE FIRST TIME THIS HAPPENED, IT TOOK 3 WEEKS TO FIX. I BOUGHT THIS VEHICLE, I SHOULD NOT HAVE TO BUY ANOTHER VEHICLE TO DRIVE. TO DATE THE BEST FUEL MILEAGE I HAVE GOTTEN IS 13.2 MILES PER GALLON. *TR

I PUT MY TRUCK INTO DRIVE AND IT HESITATES, JUMPS BACK AND FOURTH BEING REAL SLUGGISH. THE ONLY WAY OUT OF THIS IS TO FLOOR THE GAS AND LET IT PUSH THROUGH FOR ABOUT FIVE TO TEN SECONDS AND THEN IT IS DONE. WHICH IS HARD TO DO WHEN IT IS TIME TO TAKE MY KIDS TO SCHOOL AND I AM IN A SCHOOL ZONE. THIS IS VERY INTERMITTENT, BUT HAPPENS MORE OFTEN THAN NOT. IF I LET THE CAR REMAIN OFF FOR MORE THAN 15 MINUTES THEN THE CYCLE CAN CONTINUE. SOMETIMES IT STARTS UP AND DRIVES FINE. I NOTICE IT IS MORE AND MORE PREVALENT AS THE MILES CLIMB UP. IT HAS BEEN DOING THIS SINCE THE BEGINNING AND IS STILL DOING THIS. SINCE AROUND 20000 MILES THE TRUCK HESITATES ON THE ROAD AFTER DRIVING FOR SOMETIME. SO NOW IT HAPPENS WHENEVER IT WANTS TO. I HAVE READ ONLINE THAT THIS IS A COMMON OCCURRENCE THAT FORD KNOWS ABOUT, JUST DOESN'T ADMIT TO OR TRY TO FIX. MY BEST FRIEND HAD TO TRADE HIS TRUCK IN BECAUSE OF THIS PROBLEM. THIS HAS THE POTENTIAL TO BE A PROBLEM JUST LIKE THE ACCELERATION OF THE TOYOTAS. THIS PROBLEM HAPPENS SPORADICALLY BUT IT IS MORE OFTEN THAN NOT. NOW THE TRANSMISSION IS JUMPING WHEN SLOWING DOWN OR SPEEDING UP. I WAS TOLD THIS IS NORMAL, IT IS JUST THE COMPUTER GETTING USED TO MY DRIVING. I DON'T MAKE A HABIT OF MAKING MY TRUCK HESITATE AT ALL. SO THIS IS A DUMB RESPONSE THAT ONCE AGAIN, MANY PEOPLE ONLINE GET THE SAME ANSWER. I AM NEARING MY 36000 MARK. SO I KNOW THIS IS ABOUT TO COST ME OUT OF MY OWN POCKET TO FIX BECAUSE THE FORD HOUSE WILL JUST SAY NOTHING IS WRONG AND NOT FIX IT. SO MY QUESTION IS ARE TRANSMISSIONS REALLY THIS CHEAP AND WE JUST MOVE ON AND ACCEPT THAT CRAFTSMANSHIP IN AMERICA OR DO WE MAKE FORD FIX THEIR ISSUE. I HAVE PURCHASED MANY VEHICLES THROUGHOUT MY 39 YEARS IN THIS GREAT COUNTRY. I HAVE NEVER HAD A CAR ACT LIKE THIS ON SUCH A WIDE SCALE WITH NOTHING BEING DONE ABOUT IT. PLEASE HOLD THEM ACCOUNTABLE. *JB

ATTEMPTING TO PASS A VEHICLE ON THE HIGHWAY, MOTOR LOST ALL POWER AND BEGAN SHAKING. CODE CAME UP AS ENGINE MISFIRE. BROUGHT TO THE DEALERSHIP SAID KNOWN ISSUE, THEY INSPECTED DID NOT FIND ANYTHING WRONG. SINCE THAT DATE HAS OCCURRED 4-5 MORE TIMES DURING WET WEATHER ANYTIME ACCELERATING (PASSING VEHICLES, ON RAMPS).

NOTICEABLE LAG DURING ACCELERATION. MOST NOTEWORTHY INCIDENT INVOLVED PASSING AT FREEWAY SPEEDS, ENGINE BOGGED DOWN AND CAR FELT LIKE IT WAS ABOUT TO STALL. HAVE NOTICED THIS A FEW TIMES SINCE AS WELL. WE ARE IN MONSOON SEASON, HAVE HAD RAIN AND HIGHER THAN NORMAL HUMIDITY. HAVE ALSO NOTICED WHAT FEELS LIKE DELAYED AND HARD TRANSMISSION SHIFTING. FUEL CONSUMPTION/MILEAGE SEEMS TO BE AFFECTED. (WAS GETTING 17-23MPG WHEN TRUCK WAS FIRST PURCHASED IN MARCH 21013, AM NOW AVERAGING 13-15MPG). HAVE ALSO NOTICED VIBRATION/SHUDDERING WHEN ACCELERATING FROM A STOP LIGHT OR SIGN, AND DURING DOWNSHIFTING. VEHICLE IS CURRENTLY IN SHOP AS CHECK ENGINE LIGHT CAME ON ON 8/26/13. FORD IS PERFORMING A COLD-SOAK(?) THE CODE THAT THEY PULLED FROM THE VEHICLE WAS INDICATIVE OF A MISFIRE BUT THEY CANNOT DETERMINE WHAT IS CAUSING THE MISFIRE AT THIS TIME. *TT

I HAVE HAD THIS PROBLEM SEVERAL TIMES. IT SEEMED TO START IN OCTOBER 2012. I WAS TRYING TO MERGE INTO TRAFFIC AND PUSHED THE GAS PEDAL DOWN QUICKLY AND IT DID NOT MOVE FORWARD ANY FASTER. I I WAS ALMOST REAR-ENDED BY ANOTHER VEHICLE BECAUSE I COULD NOT GET ANY SPEED. IT SEEMS THAT WHEN I PUSH DOWN THE PEDAL VERY SLOWLY, IT WILL GO FASTER. BUT WHEN I NEED THE RESPONSE TO BE VERY QUICKLY, IT DOES NOT RESPOND. I HAVE HAD THIS PROBLEM WHEN I PULL MY CAMPER. IT WILL BE PERFORMING THEN ALL OF A SUDDEN, I WILL NEED TO PUSH DOWN THE PEDAL TO GET POWER UP A HILL AND AGAIN, THERE IS NO POWER. I HAVE TAKEN THIS TO THE DEALERSHIP AND THEY KEEP SAYING THAT THERE IS NO PROBLEM. I BOUGHT THIS VEHICLE TO PULL MY CAMPER. IT DOES NOT PERFORM THE WAY IT WAS TOUTED IN THEIR ADVERTISEMENTS. *TT

WHEN RETURNING FROM CULLOWEE, NC, I WAS ON THE ENTRANCE RAMP OF I-40 EAST. AT APPROXIMATELY 45 MPH, I PRESSED ON THE ACCELERATOR TO INCREASE TO HIGHWAY SPEED. THE ENGINE STARTED SPUTTERING AND THE ENTIRE VEHICLE STARTED SHAKING VIOLENTLY. THE VEHICLE NEVER GAINED SPEED UNTIL I LET OF THE ACCELERATOR COMPLETELY AND SLOWLY APPLIED PRESSURE TO THE ACCELERATOR AGAIN. THE VIOLENT SHAKING OF THE VEHICLE AND THE RESULTING DANGEROUS MERGE INTO TRAFFIC TERRIFIED MY WIFE, CHILD AND GRANDCHILD. *TR

WHILE ACCELERATING ON AN ON-RAMP TO MERGE INTO TRAFFIC ON I-90, THE ENTIRE VEHICLE VIBRATED VERY HARD, THE ENGINE THEN LOST POWER, CAUSING ELECTRIC TO SHUT DOWN, AND UNCONTROLLED DECELERATION TO OCCUR. THE CHECK ENGINE LIGHT STARTED TO FLASH. ONCE I RELEASED THE PRESSURE ON THE GAS PEDAL, AND PULLED OFF THE INTERSTATE TO AVOID ONCOMING TRAFFIC, THE POWER RETURNED AND THE ENGINE RESPONDED AGAIN. THE CATALYTIC CONVERTER WAS DETERMINED TO BE THE PROBLEM AND WAS REPLACED. NOTIFIED FORD REGIONAL SERVICE MANAGER ABOUT CONCERNS THAT THIS WAS A SAFETY ISSUE, HE RESPONDED THAT THE CAR WAS UNDER WARRANTY, AND NOTHING ELSE COULD BE DONE DESPITE ACKNOWLEDGING THAT WE COULD HAVE BEEN INVOLVED IN A VERY SERIOUS ACCIDENT DUE TO THE ENGINE FAILURE. ABOUT 2 MONTHS LATER, THE SAME PROBLEM OCCURRED, AND APPARENTLY THE COMPUTER SYSTEM WAS NOT UPDATED AS REQUIRED. AFTER THE UPDATE, IT WORKED FINE. IN DECEMBER 2012, SIMILAR SYMPTOMS OCCURRED AND THE DEALERSHIP DETERMINED IT WAS THE COIL IN ENGINE 4 AS THE PROBLEM. *TR
