THE VEHICLE WAS BEING DRIVEN FOR APPROXIMATELY 300 MILES WHEN WHILE ATTEMPTING TO PASS ANOTHER VEHICLE (ACCELERATING FROM ~50 MPH TO ~65 MPH) THE ENGINE LOST ALL POWER. AS THE VEHICLE COASTED BACK INTO THE LANE OF TRAVEL POWER WAS RESTORED TO THE ENGINE. THE FOLLOWING WEEK THE VEHICLE WAS INSPECTED BY BILL BROWN FORD IN LIVONIA, MICHIGAN.

HOWEVER THE NECESSARY PARTS WERE ON BACK ORDER FOR OVER 3 MONTHS. *TR

RELATED TO THE F-150 ECOBOOST INVESTIGATION : PE 13-018 DATE OPENED: 05/22/2013. MY TRUCK HAD THE SAME INTERMITTENT STUMBLE/MISFIRE ON ACCELERATION DESCRIBED IN THE INVESTIGATION ABOVE. I WAS DRIVING ON A HIGHWAY EARLY MORNING DURING A HEAVY RAIN STORM. AS I ACCELERATED TO PASS A CAR THE TRUCK BEGAN TO SHAKE VIOLENTLY AND LOST ALL POWER.

WHEN I'M ACCELERATING THE ENGINE STALLS, I MAY BE LEAVING A STOP SIGN CLIMBING OVER AN OVERPASS OR PASSING ANOTHER SLOWER VEHICLE. SEEMS TO HAPPEN MORE OFTEN ABOUT 40MPH TO 70MPH. *TR

IT WAS RAINING VERY HARD, AND I HAD A CELL PHONE CALL COME IN. I WAS ON I-75 SOUTHBOUND. I PULLED OFF THE ROAD TO TAKE THE CALL. AFTER APPROXIMATELY 15 MINUTES, I PUT THE TRUCK IN "DRIVE" AND STARTED TO PULL BACK ONTO I-75. AT ABOUT 25 MPH, I PRESSED THE ACCELERATOR TO THE FLOOR, AND IT SOUNDED LIKE THE TURBO WASTE GATE OPENED FULLY. THE TRUCK STOPPED MOVING FORWARD AND BEGAN TO SHAKE VERY HARD. THERE WERE 2 SEMI'S COMING TOWARD ME HONKING THEIR HORNS. I RELEASED THE ACCELERATOR AND STEERED TOWARD THE SHOULDER OF THE ROAD AGAIN. THE TRUCK LIMPED OFF THE HIGHWAY, STILL SHAKING, BUT WITH LESS VIGOR. AFTER APPROXIMATELY 2 MINUTES, THE IDLE SMOOTHED OUT SOMEWHAT, AND EVENTUALLY THE TRUCK RAN SMOOTHLY. IT TOOK ABOUT 5 MINUTES. I TOOK THE TRUCK TO BRONDES FORD IN MAUMEE TO HAVE IT CHECKED. I HAD AN APPOINTMENT FRIDAY,...

LOST POWER,ENGINE DIED UNDER HARD ACCELERATION WHILE TRYING TO PASS A CAR. CHECKED WITH THE LOCAL FORD DEALER AND THE CUSTOMER RELATIONS CENTER AT FORD AND THEY CLAIM THEY NEVER HEARD OF SUCH A PROBLEM. *TR

MY FORD F150 ECO BOOST LOST POWER SUDDENLY WHILE TRYING TO ENTER A RURAL ROUTE AT A STOP SIGN.WHILE TRYING TO ACCELERATE IT JUST DIED FOR SEVERAL SECONDS AND THEN TOOK OFF SINCE I WAS PUSHING ON THE ACCELERATOR WONDERING WHAT HAD JUST HAPPENED .THE VEHICLE HAS BEEN SHUDDERING A LOT ON ACCELERATION NOW WITH A SUBSTANTIAL LOSS OF FUEL ECONOMY . I HAVE PERSONALLY HAD IT AT TWO FORD DEALERSHIP WHICH SAY THEY CAN FIND NO PROBLEM WITH IT , BUT SHOP FOREMAN TOLD ME AND MY WIFE WE WHERE STUCK WITH IT AND TO FIX IT BY PULLING THE BATTERY CABLE OFF EVERY ONCE IN AWHILE. *TR

RAPID ACCELERATION WHILE PASSING CAUSED ENGINE TO CUT OUT AND SHUDDER. THE SECOND TIME IT HAPPENED IN APRIL 2013 I HAD TO PULL OVER AND KILL THE ENGINE SO THE COMPUTER COULD RESET. TOOK VEHICLE TO FORD DEALER FOR WARRANTY REPAIR, 2 MONTHS LATER THE PROBLEM HAS RE-OCCURRED. *TR

WHILE ATTEMPTING TO ACCELERATE BACK TO HIGHWAY SPEEDS AFTER SLOWING DOWN FOR A CAR LEAVING THE HIGHWAY, MY TRUCK LOST POWER AND STARTED TO SHUTTER. THE ENGINE LIGHT WAS FLASHING AND I WAS UNABLE TO MAINTAIN HIGHWAY SPEEDS. I EXITED THE HIGHWAY AND AFTER ABOUT 2-3 MINUTES I WAS ABLE TO ACCELERATE NORMALLY. CONDITIONS WERE WET AND THE TEMPERATURE WAS AROUND 70F. *TR

WE JUST TOOK OUR F150 (ECOBOOST V-6) ON VACATION. ON MORE THAN ONE OCCASION WE WERE TRYING TO ACCELERATE TO PASS OTHER VEHICLE'S AND WE LOST ALL POWER. WE MERGED INTO THE PASSING LANE AS WE WERE ACCELERATING AND WHEN I APPLIED MORE THROTTLE WE LOST SPEED AND POWER. AFTER THIS HAPPENED ONCE WE TRIED TO DUPLICATE IT WHEN WE ON THE INTERSTATE AND PRETEND WE WERE GOING TO PASS OTHER CARS. THE POWER LOSS HAPPENED ABOUT 50% OF THE TIME. FURTHERMORE, THIS HAPPENED WHEN WE WERE JUST TRYING TO GET ON THE INTERSTATE VIA AN ON RAMP AND GET UP TO SPEED. I DID NOT "FLOOR IT" TO GET ON THE INTERSTATE, I DID A MORE AGGRESSIVE ACCELERATION AND THE PICKUP SHUTTERED AND LOST POWER. I ASKED FORD TODAY (JUNE 5TH) IF THEY HAD A RECALL ON THE VEHICLE AND THEY SAID THEY MIGHT HAVE AN UPDATE, BUT NOTHING...

I WAS DRIVING AT HIGHWAY SPEED, AND ACCELERATED RAPIDLY TO GET OUT OF THE WAY OF A MERGING CAR. THE TRUCK SHOOK VIOLENTLY AND LOST POWER. I PULLED TO THE SIDE OF THE ROAD AND RESTARTED THE VEHICLE. THERE WAS NO "CHECK ENGINE LIGHT" OR ANY OTHER INDICATOR OF A PROBLEM DURING THE INCIDENT, OR AFTER RESTARTING THE TRUCK. WHEN I TOOK IT TO THE DEALER, THEY INDICATED THAT THEY FOUND NOTHING WRONG WITH IT. I HAVE DRIVEN THE TRUCK SINCE THEN WONDERING IF IT WOULD HAPPEN AGAIN. NOW I SEE THAT OTHERS ARE EXPERIENCING THE SAME ISSUE. KISTLER FORD IN TOLEDO, OHIO WILL HAVE A RECORD OF THIS SERVICE APPOINTMENT ON 10-21-11, AS I HAVE A COPY OF THE SERVICE DOCUMENT STATING THE ABOVE. ALTHOUGH I HAVE NO WAY TO PROVE IT, THE TRUCK HAS ALSO SEEMED TO HAVE LESS POWER SINCE THIS INCIDENT. *TR

THE TRUCK HAS A HESITATION AT BETWEEN 50 AND 60 MPH WHEN GOING UPHILL IN 6TH GEAR. IT FEELS AS THOUGH THE TRUCK TRIES TO SHIFT BUT DOES NOT. ADDITIONALLY AT LEAST TWO SEPARATE TIMES THE TRUCK HAS LOST POWER WHEN ATTEMPTING TO PASS ANOTHER VEHICLE. MOST RECENTLY ON 5/29/2013 A VEHICLE PULLED ONTO THE ROAD IN FRONT OF ME WHEN I WAS DRIVING APPROXIMATELY 55 MPH, I PULLED AROUND THE VEHICLE AND ACCELERATED TO MAKE IT PAST THE OTHER CAR AND AVOID ON COMING TRAFFIC. THE TRUCK LOST POWER AND SEEMED TO DOWN SHIFT. I LET OFF THE GAS AND TRIED TO PRESS IT AGAIN WITH NO RESPONSE. AT THIS POINT I WAS BEYOND THE OTHER VEHICLE AND WAS ABLE TO GET BACK INTO THE LANE AND AVOID ONCOMING TRAFFIC. THE TRUCK WAS STILL LOSING POWER SO I ATTEMPTED TO PRESS THE GAS AGAIN AND THE VEHICLE SHUTTERED MULTIPLE...

HAVE BROUGHT VEHICLE TO DEAL 4 TIMES AND HAVE BEEN TOLD THERE IS NOTHING THEY CAN DO. THERE IS BLACK SUT ON THE EXHAUST. I DO NOT FEEL SAFE DRIVING IN THE VEHICLE IF IT CANNOT ACCELERATE OR WILL JUST COMPLETELY SHUT OFF. *TR

I WOULD LIKE TO ADD TO THE COMPLAINTS OF THE ECO-BOOST. I WAS GOING ABOUT 75 MPH ON INTERSTATE IN ALABAMA. FLOORED IT TO PASS AND ENGINE WENT DEAD. CHECK ENGINE LIGHT CAME ON. COASTED TO SHOULDER OF HIGHWAY AND IT STARTED TO SPUTTER AND WAS ABLE TO GET TO GAS STATION ON EXIT ABOUT 200 YDS AWAY. TURNED OFF ENGINE FOR ABOUT 10 MIN. GOT BACK ON HIGHWAY(WITH ENGINE LIGHT OFF ) AND WAS ABLE TO MAKE IT BACK HOME IN EAST TEXAS. TOOK TO FORD DEALERSHIP TO GET LOOKED AT. THEY PUT ON SOME PLATE ON THE TURBO COOLING RADIATOR. LAST MONTH, TOOK IT UP TO IOWA. COMING BACK, IT DID IT AGAIN IN TULSA OK. THIS TIME ENGINE LIGHT ON ALL THE WAY HOME. TOOK TO DEALERSHIP, THEY SAID A 3 PRONGED CABLE, THE PRONGS BROKE, GOING TO ONE OF THE TURBOS. *TR

TRUCK LOST ALL FLUID FROM TRANSMISSION. FORD REPLACE SEAL IN TRANSMISSION AFTER SITTING AT DEALER FOR NEARLY 3 WEEKS. SINCE THAT TIME, I HAVE MADE MULTIPLE COMPLAINTS TO LOCAL DEALER ABOUT ENGINE STUMBLE ON HARD ACCELERATION. DEALER REPLACED AIR DEFLECTOR PER FORD SERVICE BULLETIN. TRUCK STILL STUMBLES ON HARD ACCELERATION. (06/01/2013) CURRENT MILEAGE 40,900. *TR

2011 FORD F 150 WITH ECO BOOST. WHEN I ACCELERATE THE VEHICLE STALLS OUT, BOGS DOWN, LOOSES POWER AND SHUTTERS. I HAVE TAKEN IN THE SHOP SEVERAL TIMES AND THEY COULD NOT FIX IT. I RECENTLY TOOK IT BACK IN AND HEY CHANGED THE SPARK PLUGS WHICH HELPED A LITTLE HOWEVER STILL REALLY ROUGH. I AM THINKING OF FILING. LAWSUIT AGAINST FORD. I HAVE TIED TO TRADE OUT OF THE VEHICLE AND I'M UPSIDE DOWN BECAUSE OF BAD PUBLICITY I'M BEING TOLD. I THOUGHT I HAD. LEMON BUT I GUESS IT'S ALL THE ENGINES. *TR

VEHICLE LOST POWER WHILE ACCELERATING THREE TIMES TWO TIMES IT WAS RAINING. ENGINE SHOOK ACTED LIKE IT WAS RUNNING ON 5 CYL INSTEAD OF 6. ENGINE IS 3.5 ECOBOST. ONE TIME THE CHECK ENGINE LIGHT CAME ON TWO TIMES IT DID NOT. I SENT FORD AN EMAIL ON 12/15/11 AND THEY HAD ME GO TO MY LOCAL DEALER. THE DEALER WAS UNABLE TO DUPLICATE THE PROBLEM AND THERE WAS NO CODE IN THE COMPUTER. FORD WAS PROMPT IN ANSWERING MY EMAIL. I UNDERSTAND THAT NHTSA IS LOOKING AT THE PROBLEM AND WANTED YOU TO HAVE THE INFORMATION. *TR

WHILE DRIVING ON THE HIGHWAY THE VEHICLE SEEM TO LOSE POWER I PULL OVER TO SEE IF SOMETHING MAJOR WAS WRONG BUT NOTHING I CAN TELL. I TOOK IT FOR SERVICE THEY TOLD ME THE VEHICLE NEEDED UPDATES. A MONTH LATER TOOK ANOTHER ROAD TRIP THE SAME THING HAPPEN, THIS IS VERY DANGEROUS. IT HAPPEN ON A MAJOR HIGHWAY WITH VEHICLE DRIVING AT A HIGH RATE OF SPEED AND FOR MY TRUCK JUST LOSES POWER AND SPEED ON THE HIGHWAY. *TR

TL* THE CONTACT OWNS A 2011 FORD F150. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 50 MPH, THE ENGINE LOST POWER FOR A FEW SECONDS AND THEN RESUMED NORMALLY. THE FAILURE OCCURRED WHENEVER PASSING ANOTHER VEHICLE AT SPEEDS OF 55 MPH OR HIGHER. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER NUMEROUS TIMES AND THEY WERE UNABLE TO REMEDY THE DEFECT. THE MANUFACTURER WAS NOT NOTIFIED OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 5,000. UPDATED 07/2/13*LJ

VEHICLE SHUT OFF GOING UP HILL WEATHER COLD AND DAMP TOOK TRUCK TO DEALER ON 5/20/13 FOUND NOTHING WRONG . ON 5/25/13 VEHICLE SHUT OFF 11 TIMES WHILE ACCELERATING. DROVE VEHICLE ON MON MAY 27 SHUT OFF 9 TIMES AND WE WERE NEARLY RUN OVER BY SEMI ON INTERSTATE. ENGINE LIGHT CAME ON ON TUESDAY MAY 28 DROVE TO DEALER WITH VEHICLE SHUTTING OFF OVER 10 TIMES. VEHICLE IS A LIABILITY AS WELL AS A SAFETY HAZARD FOR DRIVER AS WELL AS OTHER DRIVERS. *TR

LACK OF ACCELERATION - I HAD BEEN DRIVING ON AN INTERSTATE IN HEAVY RAIN. I THEN STOPPED FOR GAS. AFTER STOPPING FOR GAS I WENT THROUGH A TOLL BOOTH AND RE-ENTERED THE INTERSTATE. THE PICKUP WOULD NOT ACCELERATE AT A NORMAL RATE. I COULD ONLY GO 30-40 MILE PER HOUR FOR THE FIRST MILE OR SO THEN IT RETURNED TO NORMAL. THE COMPUTER SET A CODE. AFTER RETURNING HOME I TOOK THE TRUCK IN TO THE FORD DEALER WHERE I PURCHASED THE VEHICLE. THEY CHECKED THE CODE AND REPLACED THE CONVERTER ASY. *TR

ON TWO OCCASIONS ON THE SAME DATE I LOST POWER UNDER ACCELERATION AND ON THE SECOND OCCASION I WAS PRESENTED A "CHECK ENGINE" LIGHT. THE VEHICLE WAS DELIVERED TO BILLY HOWELL FORD CUMMING, GA THAT SAME DATE AND LEFT WITH THEM WHILE I WAS OUT OF TOWN FOR A COUPLE OF DAYS. I HAD JUST HAD IT IN THE SAME DEALER ON 8/30 COMPLAINING OF MISSING AND "BACKFIRING", BUT THEY CLAIMED NOTHING WAS WRONG. THE DEALER CLAIMS TO HAVE REPLACED AIR DEFLECTOR AND PROBLEM HAS NOT PRESENTED ITSELF TO THAT EXTENT AGAIN. HOWEVER, I DO EXPERIENCE FAIRLY SIGNIFICANT STALLING OR DELAY IN ACCELERATING FROM DEAD STOP. *TR

I HAVE HAD THE STALL AND/OR SHUDDER PROBLEM SEVERAL TIMES. BY FAR THE WORST IS THE DATE AND ITEMS LISTED IN THE INCIDENT INFORMATION. WHILE ATTEMPTING TO PASS ANOTHER VEHICLE ON A TWO LANE HIGHWAY, AFTER DRIVING IN A STEADY DOWNPOUR FOR AT LEAST AN HOUR, MY ECOBOOST F150 FELL FLAT ON ITS FACE. NO ACCELERATION AT ALL. IT JUST STALLED AND THE CHECK ENGINE LIGHT CAME ON. I LET OFF THE ACCELERATOR AND TRIED AGAIN WITH NO REACTION FROM THE MOTOR. I THEN FEATHERED THE THROTTLE AND WAS ABLE TO GET AROUND THE OTHER VEHICLE. THE TRUCK WOULD RUN AS LONG AS I DIDN'T TRY TO ACCELERATE QUICKLY. LUCKILY THERE WERE NO ONCOMING VEHICLES IN THE OTHER LANE. WITH DRYER WEATHER THE PROBLEM DISAPPEARED. SINCE THAT TIME I HAVE HAD IT SHUDDER A FEW TIMES WHEN TRYING TO ACCELERATE. MOSTLY IN DAMP OR HUMID CONDITIONS. *TR

AT ABOUT 30 MPH WHILE ACCELERATING THE ENGINE WILL CUT OUT AND LOSE POWER. IT WILL CHUG, CUTTING IN AND OUT FOR A FEW SECONDS BEFORE PICKING UP. THIS ALSO HAPPENS RANDOMLY WHEN GOING UP AN INCLINE. WE HAVE BEEN PUT IN A FEW DANGEROUS SITUATIONS BY THIS BEFORE BUT THANKFULLY NOTHING SERIOUS HAS HAPPENED. TOOK IT TO FORD DEALER WHERE WE BOUGHT IT AND THEY TOLD US NOTHING WAS WRONG. WE TOOK IT BACK 2 MORE TIMES AND STILL WAS TOLD THERE IS NOTHING WRONG. I CALLED TODAY TO GET THE TRUCK BACK IN AND THEY SAY THERE IS NO RECORD OF US TAKING THE TRUCK IN THE PREVIOUS 3 TIMES. *TR

AN EXAMPLE OF WHAT HAPPENS IS THIS: TRAVELING ALONG AT 45MPH, AND PULL OUT TO OVERTAKE A SLOWER VEHICLE, YOU ACCELERATE AGGRESSIVELY. UPON DOING THIS, THE TRUCK SEEMS TO STUMBLE LIKE IT'S HUNTING FOR THE APPROPRIATE GEAR (@ ABOUT 45- 50MPH). ALSO, IT FEELS LIKE AN ENGINE MIS-FIRE. IT'S A DISCONCERTING FEELING THAT THE TRUCK DOES NOT ACCELERATE AS IT SHOULD WHEN YOU NEED IT THE MOST. *TR

WENT TO PASS A CAR, LOST POWER, HAD TO DROP BACK. *TR

VEHICLE LOSES POWER AND MISSES AT AROUND 1500-2200 RPM'S. *TR

TL* THE CONTACT OWNS A 2011 FORD F-150. THE CONTACT STATED THAT WHILE AT A STOP AND ATTEMPTING TO ACCELERATE, THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE WAS NOT TAKEN TO A DEALER FOR A DIAGNOSIS. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE AND CURRENT MILEAGE WAS 13,000. *TR

VEHICLE ACTS AS IF IT WANTS TO STALL DURING RAINY CONDITIONS UPON HIGH ACCELERATION, ONLY DURING WET CONDITIONS DOES THE ECOBOOST NOT ACCELERATE WHEN NEEDED. HAS CAUSED 3 SERIOUS SITUATIONS WHERE POWER WAS NEEDED AND EXPECTED BUT TRUCK SPUTTERED AND WOULD NOT ACCELERATE. THIS HAS BEEN DANGEROUS AND DEALER HAS NO FIX. I AM UNHAPPY WITH THIS ENGINE. THERE ARE NO LIGHTS THAT COME ON TO WARN YOU OF THE CONDITION, AND YOU CANNOT TELL THERE IS A PROBLEM WHEN CRUISING AT HIGHWAY SPEEDS, ONLY WHEN YOU GO TO PASS OR NEED POWER. *TR

3.5 LITER ECOBOOST MOTORS SPUTTERED UNDER ACCELERATION ON HILL AND HAS DONE THIS SINCE BOUGHT. *TR

FORD ECOBOOST. VEHICLE HAS FEW ISSUES. FIRST THERE IS UNEXPECTED HESITATION WHEN PULLING OUT IN TRAFFIC. YOU ARE WITHOUT POWER AND SUBJECT TO BEING RUN OVER. THERE ARE TIMES WHEN AT HIGHWAY SPEEDS THE ENGINE GOES LIMP WHEN ACCELERATING LEAVING YOU IN TRAFFIC SUBJECT TO BEING RUN OVER. FORD HAS REPLACED THE CAC AND THIS HAS NOT HAPPENED SINCE. WHEN AT SPEED AND YOU ACCELERATE A SMALL AMOUNT, THE ENGINE WILL MISFIRE AND RUN ROUGH. THE LACK OF THROTTLE RESPONSE LEAVES YOU VULNERABLE WHEN PASSING. BEEN AT THE DEALER 5 TIMES FOR THESE PROBLEMS. *TR

THE VEHICLE LOST ACCELERATION IN A MAJOR HIGHWAY AND STARTED TO SMOKE. MY WIFE AND I WERE ALMOST KILLED WHEN WE TRIED TO MOVE OFF THE ROAD BY A TRACTOR TRAILER. THERE WAS NO WAY OF CONTROLLING THE VEHICLE WITH NO ACCELERATION AND MAJOR VIBRATION OF THE TRUCK. I NOTICE THAT MANY OTHERS ARE HAVING PROBLEMS WITH THE ECOBOOST F150 ENGINES AS WELL. *TR

ACCELERATING ONTO INTERSTATE FROM ON RAMP, SUDDEN LOSS OF POWER, VEHICLE SHUDDERED, LOST POWER AND SPEED. VEHICLES AROUND ME ON INTERSTATE HAD TO SWERVE TO AVOID HITTING TRUCK. TRUCK GRADUALLY REGAINED SPEED OVER NEXT 1/4 TO 1/2 MILE. APPROXIMATELY 24 HOURS AND 400 MILES LATER THE CHECK ENGINE LIGHT CAME ON. *TR

THE FIRST TIME I WAS ACCELERATING IN AN ON RAMP TO HIGHWAY SPEEDS WHEN THE ENGINE STARTED MISSING TO THE POINT I HAD TO ABORT ENTERING THE HIGHWAY AND PULL INTO THE EMERGENCY LANE TO AVOID THE ON COMING TRAFFIC. I TOOK IT TO THE DEALER AND WAS TOLD THAT NOTHING COULD BE FOUND WRONG WITH THE ENGINE. THIS HAS HAPPENED NUMEROUS TIMES AND I KEEP GETTING TOLD THAT THERE ARE NO REPORTS OF THIS HAPPENING ON OTHER ECO BOOST ENGINES. MY SOLUTION IS TO INCREASE THE DISTANCE TO GET UP TO SPEED WITH THE APPROACHING TRAFFIC WHICH IS NOT ALWAYS A SAFE PRACTICE. *TR

WHEN ACCELERATING MY F150 CUTS OUT AND HESITATES ALONG WITH A ROUGH IDLE. I HAVE TAKEN TO LOCAL FORD DEALER AND IT SHOWS TO BE A MISFIRING ISSUE IN 4 OF 6 CYLINDERS. FORD RECOMMENDED REPLACING A COUPLE OF PARTS, BUT IT DID NOT FIX THE ISSUE. THE PRINTOUT GIVEN TO ME SAID IT MAY OR MAY NOT FIX THE ISSUE AND WAS UNDER FURTHER INVESTIGATION WITH FORD ENGINEERS. THE TRUCK HAS BEEN MAINTAINED ON TIME WITH SCHEDULED OIL CHANGES, ETC...THE TRUCK NOW HAS 75K MILES AND HAS AN EXTENDED WARRANTY UP TO 125K MILES. EACH TIME THE TRUCK HAS BEGUN TO MISFIRE AND STALL OUT THE ENGINE LIGHT COMES ON AND HAS HEAVY VIBRATION UNTIL STOPPING AND RESTARTING THE TRUCK. THE DEALERSHIP REPLACED THE SPARK PLUGS BECAUSE THEY WERE ALL BURNED OUT WHICH SEEMED TO HELP, BUT CONTINUES TO IDLE ROUGH. IT'S JUST A MATTER OF TIME BEFORE THEY...

ON I-70 NEAR ST. LOUIS, I WAS IN THE INSIDE LANE AND WHEN I PRESS THE GAS PEDAL TO PASS WITH MY F-150 ECOBOOST, THE TRUCK LOST POWER AND HAD ALMOST COMPLETELY SHUT ITSELF OFF AND THE CHECK ENGINE LIGHT CAME ON. I HAD TO SHUT IT DOWN AND LET IT SET FOR ALMOST 20 MINUTES BEFORE IT WOULD RESTART CORRECTLY AND CHECK ENGINE LIGHT WOULD GO OFF. BY LUCK I HAD ENOUGH ROOM TO MOVE OVER ON THE MEDIAN OF THE HIGHWAY. *TR

TRAVELING ON I 20 DURING HEAVY RAIN , GOT OFF INTERSTATE TO REFUEL AND AFTER REENTERING INTERSTATE ACCELERATED TO GET BACK TO HIGHWAY SPEED AND TRUCK STALLED WENT TO SHAKING REAL BAD AND ENGINE LIGHT CAME ON. WOULD NOT ACCELERATE JUST SHOOK REAL BAD AND I PULLED OVER TURNED IT OFF FOR A FEW MINUTES AND RESTARTED AND CONTINUED ON. NO MORE ISSUES ONCE THE RAIN STOPPED. *TR

DATES AND MILEAGE ARE CLOSE BUT APROX. THIS IS GOING ON NOW AND FORD HAS BEEN UNABLE TO FIX THE PROBLEM AFTER BEING IN FOR REPAIR MULTIPLE TIMES. THIS IS A CONSTANT PROBLEM WITH TRUCK NOW. THE FIRST OCCURRENCE I WAS TAKING OFF FROM A LIGHT AND WENT TO ACCELERATE AND TRUCK STARTED HESITATING AND CHECK ENGINE LIGHT CAME ON. FORD SAID IT WAS INTERCOOLER AND FIXED THAT BUT DROVE TRUCK FROM DEALERSHIP AND DID NOT GET 1/4MILE DOWN ROAD BEFORE IT HESITATED AGAIN. THEN FORD SAID IT WAS COIL PACK AND SEEMED TO FIX IT BUT THEN IT STARTED RIGHT BACK UP WITHIN A MONTH. *TR

I WAS READING ON LINE ABOUT THE PROBLEM WITH THE FORD F-150 ECO BOOST ENGINE AND REALIZE THAT THIS HAS HAPPEN TO ME SEVERAL TIMES AND SCARE THE [XXX] OUT OF ME. NOT REALIZING THAT THERE WAS A PROBLEM WITH THE TRUCK. AS A MATTER OF FACT WHEN I TRY TO USE THE PASSING GEAR TO PASS THE TRUCK FELL ON IT FACE. I WOULD LIKE THIS TO GO ON A REPORT OF ENGINES LOSING POWER DURING HARD ACCELERATION SUCH AS WHEN PASSING. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

I OWN A 2011 F150 3.5L TURBO ECOBOOST TRUCK. IT HAS CAUSE ME NOTHING BUT GRIEF! VIOLENT HESITATION/SHAKING ON HIGHWAY WHEN PASSING. LOSE OF POWER WITH ENGINE LIGHT COMING ON LEFT ME ON THE ROAD TWICE. FINALLY ENGINE BLOCK EXPLODED WITH A ROD SHOOTING OUT OF ENGINE. OIL SPAYED ALL OVER ENGINE CREATING THICK BLACK SMOKE AND POOR VISIBILITY. PULLED OVER HAD TO GET OUT OF THE TRUCK BECAUSE SMOKE WAS INSIDE. COUNTLESS FORD ATTEMPTS TO FIX THE ISSUE AND NOTHING WORKED. EVENTUALLY THE WHOLE ENGINE WAS REPLACED. I JUST RECEIVED MY TRUCK BACK AND HAVE LOST TOTAL FAITH IN THIS PRODUCT. THERE IS SOMETHING WRONG WITH THIS ENGINE! I HAVE ALL DOCUMENTATION FOR THIS. *TR

SLOWED DOWN TO MAKE A TURN, TRIED TO ACCELERATE AND ENGINE HESITATED FOR FIVE SECONDS. TRIED TO MERGE INTO TRAFIC AND ENGINE HESITATED . THIS HAS HAPPENED MANY TIMES, HAD TO PULL OVER ON SHOULDER TILL ENGINE PICKED UP SPEED. *TR

I RECENTLY SAW WHERE THE NHTSA WAS INVESTIGATING PERFORMANCE ISSUES (BOGGING DOWN,HESITATION) OF FORDS ECOBOOST 3.5L V6. I HAVE HAD THIS PROBLEM ALONG WITH SEVERE DOWNSHIFTING WHEN DECELERATING CAUSING SKIDDING AND LOSS OF CONTROL IN WET OR ICY CONDITIONS. I REPORTED THIS PROBLEM TO TONY FREDERICK VP FORD CUSTOMER SERVICE WHO SENT A FACTORY REP TO LOOK AT THIS AND OTHER ISSUES. WAS TOLD VEHICLE WAS FUNCTIONING NORMALLY. THE HESITATION WHEN ACCELERATING FOR ME OCCURS REGULARLY. I DO NOT BELIEVE ITS ISOLATED TO WET OR HUMID CONDITIONS. *TR

AFTER 4 HOURS OF STEADY HIGHWAY DRIVING UPON ATTEMPTING TO PASS A VEHICLE THE TRUCK FAILED TO DOWNSHIFT , LOST POWER ( REQUIRING ME TO ABORT MANEUVER) AND BEGAN BUCKING... THERE WAS NO CEL. TOOK THE CAR TO THE DEALER AND THEY INSPECTED THE TRUCK FOUND NO CODES AND SAID NO PROBLEM FOUND. THEY SAID THEY RELOADED THE PROGRAMMING FOR THE TRANSMISSION. THIS VEHICLE HAS EXPERIENCED THIS PROBLEM NUMEROUS TIMES SINCE THE FIRST OCCURRENCE. ALWAYS HAPPENS WHEN ACCELERATING AND CREATES DANGEROUS LOSS OF POWER AT CRITICAL DRIVING PERIODS. *TR

DRIVING ON INTERSTATE. ATTEMPTED TO PASS SLOW MOVING VEHICLE. TRUCK SHUDDERED AND LOST ABILITY TO ACCELERATE. THIS HAS HAPPENED SEVERAL TIMES. DEALERSHIP HAS BEEN UNABLE TO FIX PROBLEM, AND HAS JUST REPROGRAMMED COMPUTER EACH TIME. THEY NOW SAY THAT IT'S AN INTERCOOLER ISSUE. WAS TOLD PART IS ON BACKORDER, AND WOULD BE IN BY END OF APRIL. HAVE ATTEMPTED TO CONTACT THEM RE: PART AVAILABILITY, WITH NO RESPONSE, AND IT'S NOW MAY 23RD. THIS TRUCK IS DANGEROUS, AND HAS LEFT ME ON THE SIDE OF THE ROAD MORE THAN ONCE. *TR

THE VEHICLE JUST DOESN'T ACCELERATE WITHOUT HESITATING. *TR
