2012 FORD F-150 Engine Problems

NEEDED TO ACCELERATE AND WHEN THROTTLE WAS APPLIED THE ENGINE SHUTTERED AND LOST ALL POWER UNTIL I PULLED OVER TO THE SHOULDER AND TURNED OFF AND RESTARTED TRUCK. THEN RAN FINE. IT HAS DONE THIS THREE TIMES UNDER SAME TYPE OF CONDITIONS. VERY DANGEROUS. *TR

TRUCK STUMBLES AND STUTTERS AT 62 MPH AND AROUND 1400 RPM WHEN ATTEMPTING TO ACCELERATE. FORD DEALERSHIP REPLACED CAC AND UPGRADED SOFTWARE, THIS HELPED THE PROBLEM BUT DID NOT FIX THE PROBLEM. I REPORTED BACK TO THE DEALER ABOUT THE CONTINUED PROBLEM AND THERE RESPONSE WAS THAT I WAS FEELING TURBO LAG AND FORD CORP DOES NOT CURRENTLY HAVE A FIX, CHECK BACK IN A FEW MONTHS. *TR

AFTER DRIVING ALL DAY IN THE RAIN, I WENT UP A FREEWAY ON-RAMP ACCELERATING TO MERGE WITH TRAFFIC. ENGINE STARTED SHAKING BADLY, AND LOST ALMOST ALL POWER. I MOVED TO THE RIGHT SAFETY LANE TO GET OUT OF TRAFFIC. AFTER ABOUT ONE MINUTE THE ENGINE REGAINED POWER, STOPPED SHAKING, AND I WAS ABLE TO CONTINUE NORMALLY. I WENT ONLINE AND DISCOVERED THAT MANY F150 ECOBOOST OWNERS HAVE THE SAME PROBLEM BUT FORD REFUSES TO ACKNOWLEDGE THE ISSUE, AND DOES NOT OFFER A RECALL OR STANDARD FIX. SO I JUST AVOID HARD ACCELERATION ON RAINY DAYS AND HAVE NOT HAD THE ISSUE AGAIN. IT IS A DANGEROUS PROBLEM THOUGH. *TR

LOSS OF POWER WHILE DRIVING,... THIS HAS HAPPENED SEVERAL TIMES AND THE DEALERSHIP (JOE MACHENS FORD) DENIES ANY PROBLEM WITH TRUCK. THIS HAS ALSO HAPPENED TO MY SON [XXX]2012 F-150 AND HE HAS BEEN TOLD THERE'S NOTHING WRONG ALSO. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

IN A LIGHT RAIN I TRIED TO PASS A TRUCK BUT WHEN I PUSHED ON THE GAS THE ENGINE STALLED. I WAS LUCKY TO GET BACK IN MY DRIVING LANE. THIS HAS HAPPENED 4 TIMES, THREE WHILE ATTEMPTING A PASS. I AM NOW RELUCTANT TO ATTEMPT A PASS. *TR

INCIDENT 1. WEATHER: CLOUDY WITH SOME SNOW AROUND 20 DEGREES.WHEN ACCELERATING ON TO INTERSTATE 70 IN E. ILLINOIS THE ENGINE STUMBLED AND LOSS POWER. THE ON RAMP HAD AN UPHILL GRADE AND WHEN THE VEHICLE HIT 35-40 MPH, IT LOST ALL POWER AND SOUNDED LIKE IT WAS STRUGGLING TO GET FUEL. I WAS ABLE TO PULL TO THE SIDE OF THE ROAD, PUT IT IN PARK. I TRIED TO REV THE ENGINE IN PARK BUT IT WOULD JUST STUMBLE. I TURNED THE ENGINE OFF AND WAITED A FEW MINUTES THEN RESTARTED IT AND IT AND IT SEEMED TO WORK AS EXPECTED. THIS HAS HAPPENED 3 TIMES SINCE MARCH 4TH WITH THE LAST TIME BEING ON MAY 9TH. INCIDENT 2. WEATHER: PARTLY CLOUDY IN THE 30'S., MARCH 7TH, SAME CONDITIONS AS ABOVE ENGINE STUMBLED AND LOSS POWER ACCELERATING ON TO INTERSTATE 376 IN W. PA INCIDENT 3. WEATHER: NIGHTTIME, IN THE...

PULLING ON THE HIGHWAY AND ACCELERATING THE TRUCK SEEMS TO HESITATE WHEN YOU NEED THE POWER. THIS PARTICULAR DAY WAS HUMID BUT IT HAPPENS SOMETIMES IN CLEAR WEATHER. *TR

ENGINE STALLED DURING HARD ACCELERATION. IT HAD BEEN SITTING IDLING TO WARM UP ON A COLD MORNING. WHEN PULLING ONTO THE HIGHWAY AND ACCELERATING TO MOVE INTO TRAFFIC, THE ENGINE STUTTERED AND STALLED. HAD TO PULL OVER OUT OF TRAFFIC. *TR

INTERMITTENT STUMBLE/MISFIRE ON ACCELERATION FROM HIGHWAY SPEEDS, ENGINE FEELS LIKE IT IS IN LIMP MODE, THIS HAS HAPPENED FOUR TIMES. *TR

WHILE DRIVING AT HIGHWAY SPEEDS AND ATTEMPTING TO PASS A SLOWER CAR, THE TRUCK LOST 50% OF ITS POWER. IT BEGAN TO MISS FIRE, AND ACT LIKE IT HAD BAD GAS OR SOMETHING. I ALSO STARTED TO NOTICE THAT IF YOU TURN A CORNER ON WET PAVEMENT AND YOU LOSE TRACTION, THE TRUCK MADE THE SAME GURGLING SOUND WITH POWER LOSS. THIS HAS HAPPENED SEVERAL TIMES. I HAVE ALSO NOTICED THAT I GET VERY BAD GAS MILEAGE AVERAGING 12 MPG ON THE HIGHWAY. I TOOK THE TRUCK IN AND THEY REPROGRAMMED IT. I THINK ALL THIS DID WAS CUT BACK THE POWER TO HELP PREVENT DETONATION OR MISS FIRES. AFTER THIS THE TRUCK WAS A COMPLETE DOG. BAD MILEAGE AND NO POWER. I RECENTLY SENT THE TRUCK BACK AND THEY REPLACED SOME PARTS WITH THE INTERCOOLER. IT ISN'T 100% FIXED BUT IT IS BETTER. MILEAGE PICKED UP TO 15 MPG...

WHILE DRIVING DOWN THE HIGHWAY, VEHICLE WILL GO INTO "LIMP" MODE. POWER REDUCES ON VEHICLE AND WILL NOT ALLOW TO MAINTAIN HIGHWAY SPEEDS. THIS HAS HAPPENED MANY TIMES DURING A TRIP ESPECIALLY IN HUMID AND COLD CONDITIONS. THE SCARIEST SITUATION HAS BEEN WHILE TOWING A TRAILER. TRUCK WENT INTO THE REDUCED POWER LIMP MODE AND WAS ALMOST RUN INTO BY A SEMI TRUCK. I HAVE HAD THE TRUCK INTO THE DEALERSHIP SEVERAL TIMES WITH ATTEMPTS TO REPAIR. THEY HAVE REPLACED A FEW ENGINE SENSORS THAT THEY CLAIM WERE CAUSING ISSUES, BUT THE TRUCK STILL HAD ISSUE DURING COLDER WEATHER. *TR

UPON ENTERING THE ENTRANCE RAMP TO A HIGHWAY THE ENGINE EXPERIENCED A COMPLETE LOSS OF POWER AROUND 35 MPH. ALL ATTEMPTS TO INCREASE ACCELERATION WERE FUTILE AND THE ENGINE WENT INTO "LIMP MODE" AND WOULD NOT RESPOND TO ANY INPUT. AFTER 30 SECONDS OF UNSUCCESSFULLY ATTEMPTING TO ACCELERATE I TURNED ON MY HAZARD SIGNAL AND BEGAN TO MOVE TOWARD THE SHOULDER TO AVOID CAUSING A DANGEROUS SITUATION. THE VEHICLE THEN SUDDENLY BEGAN TO RESPOND AND ACCELERATED NORMALLY BACK ONTO THE HIGHWAY. *TR

TRAVELING AT 60 + / - MPH AND ATTEMPTED TO PASS ANOTHER VEHICLE UNDER NORMAL CONDITIONS. ENGINE LOST POWER ON ACCELERATION AND SEEMED TO SPUTTER. THIS IS STRANGE AS THE GAS WAS NOT "PUNCHED" OR ANYTHING OUTSIDE OF NORMAL PASSING ACCELERATION. INITIALLY I THOUGHT I MAY BE OUT OF GAS OR SOMETHING BUT THIS WAS NOT THE CASE. I HAVE NOTED POWER LOSS TWO OTHER TIMES BUT DID NOT THINK ANYTHING OF IT AS THE ENGINE RETURNED TO NORMAL ONCE I BACKED OFF THE GAS. THE ONE DIFFERENCE THIS TIME IS THE ENGINE MADE A VERY ROUGH VIBRATION WHICH CAUSED OTHERS IN THE TRUCK TO ASK IF I WAS HAVING ENGINE TROUBLE. *TR

AS I WENT TO PASS SLOW MOVING VEHICLES IN A BRAND NEW F-150 ECOBOOST WITH 4,000 MILES ON IT COMPLETELY LOST POWER TWICE WITHIN 30 MINUTES AND SHUT DOWN FOR ABOUT 20 SECONDS. ONCE I WAS SLOWED TO ABOUT 15 MPH ON A BUSY STREET IT WENT BACK TO NORMAL AND THE ACCELERATOR STARTING WORKING AGAIN. *TR

VEHICLE LOST POWER WHILE PASSING ANOTHER VEHICLE. UNABLE TO COMPLETE PASSING MANEUVER. THIS IS A SAFETY ISSUE THAT NEEDS TO BE ADDRESSED. *TR

WHILE DRIVING DURING A LIGHT RAIN, I STARTED TO PASS A SLOWER MOVING VEHICLE. WHEN I ACCELERATED TO PASS, THE ENGINE STALLED TO IDLE SPEED, CAUSING ME TO HAVE TO ABORT THE PASS AND PULL BACK IN BEHIND THE VEHICLE. *TR

I HAVE EXPERIENCED TWO SEPARATE OCCURRENCES WHERE THE TRUCK WOULD VIOLENTLY LOSE POWER DURING ACCELERATION DURING RAINSTORMS. THE FIRST TIME THE CHECK ENGINE LIGHT FLASHED BUT WENT AWAY. THE DEALER TOLD ME IT WAS PROBABLY THE TRACTION CONTROL, SINCE NO CHECK ENGINE LIGHT WAS LOGGED IN THE SYSTEM. THE SECOND TIME WAS APRIL 24TH, 2013, AND THE TRUCK HAD APPROXIMATELY 11,000 MILES. I WAS TRAVELING APPROXIMATELY 70MPH AND PASSING TWO 18 WHEELERS ON THE INTERSTATE DURING A HEAVY RAINSTORM AND THE TRUCK BEGAN TO MISFIRE AND STUTTER AND HAD NO POWER. I HAD TO SWERVE BETWEEN THE SEMIS AND COAST TO A STOP ON THE SHOULDER TO NARROWLY AVOID A POTENTIALLY FATAL CRASH DUE TO THE LOSS IN POWER. THE CHECK ENGINE LIGHT STAYED ON THIS TIME, SO WHEN I TOOK IT TO THE DEALER I SPECIFICALLY ASKED ABOUT THE TURBO INTERCOOLER ISSUES THAT THE ECOBOOSTS HAVE BEEN REPORTED TO...

I WAS ABOUT TO ENTER HIGHWAY FROM RAMP, TRIED TO ACCELERATE ENGINE STARTED MISSING, LOSS OF POWER HAD TO PULL OVER TO SIDE OF ROAD AND TRY AGAIN, WAS ALMOST HIT FROM REAR. CONDITIONS, RAIN. *TR

V6 ECOBOOST MY FAMILY AND I WERE TRAVELING IN HEAVY RAIN ON I65 IN BIRMINGHAM, AL. I PULLED INTO THE FAR LEFT LANE TO PASS SLOWER VEHICLES. WHEN I ACCELERATED THE TRUCK BEGAN TO SHAKE VIOLENTLY AND RAPIDLY LOSE SPEED AND POWER. SEVERAL VEHICLES INCLUDING A SEMI HAD TO TAKE EVASIVE ACTION TO AVOID A COLLISION. THE SECOND TIME WAS ON MY RETURN TRIP HOME. WE WERE TRAVELING ON A TWO LANE ROAD IN FOGGY CONDITIONS. WE CAME TO AN AREA WHEN THE ROAD SPLIT SO YOU COULD PASS SLOWER VEHICLES. I, ALONG WITH A CAR FOLLOWING, WENT TO PASS A SLOWER VEHICLE WHICH HAD MOVED TO THE RIGHT. WHEN I WAS ALONGSIDE THE SLOWER VEHICLE MY TRUCK BEGAN TO SHAKE AND LOSE SPEED. I HAD TO TAKE EVASIVE BRAKING ACTION TO FALL IN BEHIND THE VEHICLE TO MY RIGHT BECAUSE THEY WERE RUNNING OUT OF ROOM. THE VEHICLE FOLLOWING...

LOSING POWER, VEHICLE SHAKE , CHECK ENGINE LIGHT. JE DEMEURE AU QUEBEC, JE PARLE FRANCAIS. SI VOUS AVEZ D AUTRE INFO A ME DEMANDER, N HESITER PAS. *TR

DRIVING IN RAINING CONDITIONS, WHEN ACCELERATING I WOULD LOOSE POWER WHEN THE TURBO CHARGERS KICKED IN. IT WAS AS IF THE TURBO CHARGERS WERE PICKING UP THE MOISTURE CAUSING THE ENGINE TO MISFIRE AND WOULD LOOSE ALL POWER FOR ACCELERATION. EVEN AFTER THE RAIN STOPPED, THIS ACCELERATION PROBLEM STAYED WITH THE VEHICLE FOR THE REMAINDER OF THE TRIP. THE NEXT MORNING, STILL HAD SAME PROBLEM BUT AS THE TEMPERATURE WENT UP AND HUMIDITY DECREASED THE PROBLEM GOT LESS SEVERE AND BY THE END OF THE SECOND DAY THE ACCELERATION HAD RETURNED TO NORMAL. THE FIRST OCCURRENCE WAS WHEN I WAS PASSING A SEMI TRAILER, I TRIED TO PULL OUT AROUND IN PASSING ZONE ON A SINGLE LANE IN EACH DIRECTION, WHEN THE ENGINE DIDN'T RESPOND I HAD TO BREAK AND FALL BACK BEING THE SEMI. LUCKILY, THIS OCCURRED AS I PULLED OUT TO PASS THE SEMI, IF IT HAD HAPPENED...

I WAS MERGING INTO TRAFFIC ON I-10 IN FLORIDA FROM AN ENTRANCE RAMP. I WAS GOING 55 MPH WHEN I HAD TO ACCELERATE IN ORDER TO MERGE WITH TRAFFIC. UPON ATTEMPTING TO ACCELERATE, THE ENGINE LOST POWER AND BEGAN TO SHAKE CAUSING ME TO HAVE TO BRAKE REALLY HARD AND MOVE TO THE SHOULDER OF THE ROAD SO THAT I WOULDN'T COLLIDE WITH TRAFFIC ALREADY MOVING AT 70 MPH IN THE LANE I WAS ATTEMPTING TO MERGE. THIS IS THE FIRST OF SEVERAL INCIDENCES IN WHICH THE VEHICLE LOST POWER UNDER ACCELERATION. *TR

STRAIGHTENING OUR VEHICLE IN PARKING PLACE AT HOME DEPOT. SLOWLY (~2MPH) GOING FORWARD WITH FOOT ON BRAKE WHEN ENGINE SUDDENLY SPEED UP. MASHED DOWN HARD ON BRAKE WHILE SHIFTING INTO NEUTRAL. TIRES OR CLUTCH SCREAMING SO LOUD IT DREW A GROUP OF YARDMEN UNLOADING A TRUCK NEARBY. SHORTLY AFTER GETTING IT SHIFTED INTO NEUTRAL ENGINE RESUMED NORMAL OPERATION. TOOK TO FORD DEALER IMMEDIATELY AND WILL BE EVALUATED AFTER THE HOLIDAY. SEVERAL TIMES IN THE WEEK PRIOR TO INCIDENT I NOTICED SOME SLIGHT "STUTTERING" OF THE VEHICLE WHEN SLOWLY MOVING FORWARD TO PARK IN DRIVEWAY, ALSO NOTICED FOR THE PAST 1 TO 1.5 MONTHS THERE HAS BEEN A 2+ MILE PER GALLON DECREASE IN FUEL MILEAGE RUNNING OVER THE SAME ROUTES. *TR

MULTIPLE ACCELERATION ISSUES, ESPECIALLY WHEN ATTEMPTING TO PASS ANOTHER VEHICLE AND/OR WHEN ACCELERATING ABRUPTLY. I HAVE ALSO NOTICED CONDENSATION FROM THE EXHAUST WHEN FIRST STARTING THE VEHICLE IN THE MORNING ON MULTIPLE OCCASIONS. *TR

MY WIFE AND I WERE COMING HOME GOING ABOUT 55 MPH AND I WENT TO PASS A SLOWER CAR. AS I PULLED ON THE PASSING LANE AND WENT TO PASS THE ENGINE START TO CUT OUT THE MORE I PUSHED ON THE ACCELATOR THE SLOWER THE TRUCK WENT. IT HAS DONE THIS TWO MORE TIME. I'M FIXING TO TAKE TO FORD IN A FEW WEEKS. THIS COULD BE A SAFETY PROBLEM THE TRUCK HAS THE 3.5 ECO ENGINE. *TR

MY WIFE AND I WERE DRIVING IN MAINE ON VACATION HAULING A 3600 LB 14 FOOT CAMPER. IT WAS EARLY EVENING AND RAINING, I WAS IN A FLAT AREA COMING INTO A STEEP HILL SO I ACCELERATED HARD AND THE ENGINE STAGGERED HARD. IT WAS LIKE A HAMMERING FOR SEVERAL SECONDS AND A TOTAL LOSS OF ACCELERATION. I THOUGHT I HAD ACTUALLY BROKEN THE ENGINE SOME HOW. A FEW SECONDS LATER THE HAMMERING STOPPED AND THE TRUCK RETURNED TO NORMAL. WHEN I TALKED TO MY FORD TECH ABOUT IT HE SAID IT WAS BAD GAS. THE ENGINE SINCE THEN HAS HAD A TICKING SOUND THAT THE TECH SAYS IS THE FUEL INJECTORS WORKING, I'M NOT SO SURE SINCE IT DID NOT MAKE THAT SOUND BEFORE THE ABOVE DESCRIBED INCIDENT. IT HAS NOT RECURRED, BUT I HAVE BEEN CAREFUL NOT TO EXPOSE THE VEHICLE TO HARD ACCELERATION AGAIN, BUT THAT HARDLY...

TL* THE CONTACT OWNS A 2012 FORD F-150. THE CONTACT STATED THAT WHILE DRIVING 30 MPH, THE CONTACT ATTEMPTED TO ACCELERATE BUT THE VEHICLE DECELERATED AND SHOOK VIOLENTLY. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE ECOBOOST CHAMBER WAS DEFECTIVE AND NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS REPAIRED. THE FAILURE MILEAGE WAS 4,000 AND THE CURRENT MILEAGE WAS 9,000. *TR

TL* THE CONTACT OWNS A 2012 FORD F150. THE CONTACT STATED THAT THE VEHICLE LOST ACCELERATION POWER WHILE TOWING A BOAT. THE CONTACT WAS ABLE TO SHIFT THE GEAR MANUALLY AND REGAIN ACCELERATION. THE VEHICLE WAS TAKEN TO THE DEALER TO HAVE A DIAGNOSTIC PERFORMED, WHICH WAS UNABLE TO LOCATE A FAILURE CODE. THE DEALER ALSO TEST DROVE THE VEHICLE AND WAS UNABLE TO DUPLICATE THE FAILURE. THE CONTACT STATED THAT MOISTURE PENETRATED THE ECO-BOOST AND CAUSED THE VEHICLE TO LOSE ACCELERATION. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 28,000 AND THE APPROXIMATE CURRENT MILEAGE WAS 28,300.

I WAS DRIVING ON A 2 LANE HIGHWAY, BEHIND A SEMI TRUCK, WITH SEVERAL CARS BEHIND ME. WE CAME TO A PASSING ZONE AND I BEGAN TO PASS THE SEMI TRUCK. I MOVED TO THE ONCOMING LANE AND ACCELERATED, BUT THE TRUCK LOST POWER. I BEGAN SLOWING DOWN IN THE ON COMING LANE, BUT COULDN'T RETURN TO THE RIGHT LANE BECAUSE THE VEHICLES THAT WERE BEHIND ME WERE PASSING ME IN THE RIGHT LANE AND I HAD A VEHICLE DIRECTLY BEHIND ME THAT WAS FOLLOWED ME TO PASS THE SEMI TRUCK. I LOCKED OUT 5TH AND 6TH GEARS ON THE TRANSMISSION TO GAIN SOME RPM BUT THE VEHICLE STARTED TO SHUDDER VIOLENTLY. I MOVED TO THE SHOULDER OF THE ON COMING LANE AND SHUT THE VEHICLE OFF. I SAT ON THE SHOULDER FOR SEVERAL MINUTES, GOT OUT OF THE VEHICLE AND CHECKED UNDER IT FOR FLUIDS. THERE WERE NO FLUIDS...

TRUCK HAS 3.5L ECOBOOST V6 ENGINE. 18 MAY 2013. WAS TRAVELING ON TWO LANE HIGHWAY IN CENTRAL GEORGIA. PULLING A 3000 LB UTILITY TRAILER. HAD BEEN DRIVING IN LIGHT RAIN FOR ABOUT ONE HOUR. SPEED LIMIT WAS 55. I WAS FOLLOWING A CAR THAT WAS GOING ABOUT 45 MPH. WHEN I GOT TO A SLIGHT UPHILL GRADE THERE WAS A PASSING LANE AVAILABLE AND CLEAR OF OTHER VEHICLES. I PULLED TO THE LEFT LANE TO PASS THE SLOWER VEHICLE IN FRONT OF ME. I PRESSED THE ACCELERATOR ABOUT 3/4 DOWN TO ATTEMPT A DOWNSHIFT OF GEARS. THE TRUCK IMMEDIATELY BEGAN VIBRATING/SHUDDERING AND LOST ALMOST ALL POWER. I PULLED BACK TO THE RIGHT LANE AND HELD LIGHT PRESSURE ON THE ACCELERATOR AND WAS ABLE TO MAINTAIN ABOUT 20 MPH SPEED. I HELD THE THROTTLE STEADY AND AFTER ABOUT TWO MINUTES THE ENGINE REGAINED FULL POWER AND I PROCEEDED ON MY TRIP....

VEHICLE SINCE BRAND NEW HAS A STUTTERING/STALLING ISSUE AT 55MPH AND THE DEW POINT IS HIGH. ATTEMPTING TO PASS A VEHICLE ACCELERATING FROM 55MPH AND THE TRUCK EITHER STUTTERS OR STALLS. THIS ALMOST CAUSED A HEAD-ON COLLISION. I AM SCARED TO PULL OUT IN TRAFFIC OR PASS ANYONE DUE TO THE INHERENT ISSUE. FORD DID REPLACE A INTERCOOLER/CAC FOLLOWING TSB 12-10-19. THIS HAS NOT FIXED THE PROBLEM. WE. I RETURNED THE TRUCK STILL BROKE. THE SERVICE MANAGER AT THE DEALERSHIP TOLD ME HE HAS THE SAME TRUCK AND THAT IT IS AN INHERENT ENGINE PROBLEM FORD HAS ACKNOWLEDGED BUT THEY COULD NOT DO ANYTHING FOR ME. I AM WORRIED EVERYDAY I MIGHT DIE DRIVING MY TRUCK AND EVEN MORE UPSET THAT I PAY MONTHLY FOR SOMETHING THAT IS BROKE. *TR

ON MONDAY DECEMBER 11, MY WIFE AND I LEFT ON A TRIP TO INDIANA WITH APPROXIMATELY 10,400 MILES ON THE TRUCK. AFTER A STOP, AT THE BOWLING GREEN, KY., REST STOP, I PROCEEDED TO RETURN TO TRAFFIC ON INTERSTATE 65. AFTER DETERMINING I COULD SAFELY ACCELERATE IN FRONT OF TWO SEMI-TRAILER TRUCKS, I ENTERED THE HIGHWAY AT APPROXIMATELY 50 MPH AND WENT TO FULL THROTTLE. INSTEAD OF ACCELERATING, THE ENGINE WENT INTO A TOTAL LOSS OF POWER. AMID THE BLOWING OF AIR HORNS AND MY WIFE'S SCREAMS I WAS LUCKY ENOUGH TO AVOID A COLLISION BY YANKING THE TRUCK ONTO THE EMERGENCY LANE. THE ENGINE DID NOT STOP RUNNING, BUT APPEARED (TO ME) TO BE TOTALLY FLOODED. THE ENGINE RAN ON ?? (NUMBER OF) CYLINDERS FOR APPROXIMATELY ONE EIGHTH OF A MILE BEFORE RETURNING TO RUNNING ON ALL CYLINDERS. I DO NOT THINK THE SERVICE DEPARTMENT BELIEVED ME WHEN THEY...

I WAS DRIVING AT 60MPH IN A FOGGY RAIN WHEN I BEGAN UP A HILL. I MOVED TO THE LEFT LANE AS THE TWO CARS IN FRONT OF ME WERE SLOWING WHEN MY ENGINE STUTTERED AND I LOST POWER CAUSING ME TO DRASTICALLY SLOW DOWN. A SERVICE REQUIRED MESSAGE FLASHED ON MY DISPLAY AND A ADVANCTRAC SERVICE LIGHT ILLUMINATED. FOR THE REMAINDER OF THE TRIP I HAD VERY LIMITED POWER AND THE VEHICLE WAS GEAR HUNTING. ONCE POWERED OF AND POWERED BACK ON THE VEHICLE OPERATED NORMALLY. *TR

3.5-LITER V6 ECOBOOST ENGINE SHUDDER, SHAKE AND THEN RAPIDLY LOSE POWER WHILE I'M ACCELERATING. ADVERTISED GAS MILEAGE OF 22 IS IMPOSSIBLE; MORE LIKE 16 HIGHWAY AND 14.4 IN CITY. I HAD THE ENGINE CHECKED AT FORD DEALERSHIP BUT NO PROBLEMS FOUND! *TR

WHILE TRYING TO ACCELERATE FROM 50 UP TO THE POSTED SPEED LIMIT OF 70 ON INTERSTATE HIGHWAY 10, THE ECOBOOST ENGINE IN MY TRUCK STALLED AND STARTED TO MISFIRE AND SHUTTER SO SEVERELY CAUSING MY SPEED TO DECREASE THAT I HAD TO PULL OVER TO THE SIDE OF THE ROAD TO PREVENT FROM GETTING RUN OVER. *TR

FORD'S ECOBOOST ENGINE V6 3.5L CUT POWER WHEN ATTEMPTING TO MERGE ON TO HIGHWAY AT 55MPH. SEVERE ENGINE VIBRATIONS ENSUED. VERY DANGEROUS ISSUE IF THERE IS A LOT OF TRAFFIC BEHIND PERSON DRIVING. TRUCK STILL HAS LESS THAN 15K MILES, HAS BEEN IN THE SHOP 2X ALREADY IN ATTEMPTS TO RECTIFY THE ISSUE, AND STILL HAS PROBLEM. *TR

ON MY WAY HOME LAST OCTOBER AFTER PICKING UP MY NEW F-150 AT THE DEALERSHIP I WAS ATTEMPTING TO PASS A CAR ON THE INTERSTATE. IT WAS ON A HILL AND WHEN I PUSHED ON THE GAS TO TRY AND PASS THE CAR THE TRUCK SHUTTERED AND SLOWED DOWN LOSING POWER AND SPEED. THE BEST WAY TO DESCRIBE IT WAS THAT IT "BOGGED" DOWN. THERE WAS NO ENGINE LIGHT. HOWEVER, I KNEW SOMETHING WAS WRONG, BUT I FIGURED I WOULD HAVE IT CHECKED OUT WHEN I CAME IN TO GET THE RUNNING BOARDS INSTALLED. A COUPLE OF DAYS LATER, HOWEVER, AN INCIDENT OCCURRED THAT WAS A BIT MORE DANGEROUS. I WAS ATTEMPTING TO PASS A SLOWER CAR ON A TWO LANE HIGHWAY (NO HILL) WHEN THE SAME THING HAPPENED WHEN I PUSHED DOWN ON THE GAS TO SPEED UP TO PASS--THE TRUCK SIMPLY BOGGED DOWN--LOSING POWER AND SPEED. THE ENGINE...

LOSS OF POWER WHEN ACCELERATING FROM A STOPPED POSITION, MORE FREQUENTLY AS TIME GOES ON, AND WHEN TRUCK HAS BEEN DRIVEN FOR LONG PERIODS OF TIME. WHEN FIRST BOUGHT VEHICLE, THERE WAS A SHUDDER AND A SHAKE EXTREMELY NOTICEABLE AT 45 MPH. THE TRUCK WAS BROUGHT INTO THE FORD DEALERSHIP WHERE IT WAS PURCHASED AND CHECKED FOR A DEFLECTOR PLATE. THE DEFLECTOR PLATE WAS INSTALLED, SO A NEW INTERCOOLER WAS ORDERED AND A LONG WAIT WITH THIS TROUBLESOME PROBLEM OCCURRED. THE NEW INTERCOOLER ARRIVED AND WAS PUT IN, BUT THE SAME PROBLEMS PERSIST. THE SHUDDER AND SHAKE IS NOW MORE NOTICEABLE AT 35MPH BUT IS STILL THERE AND NOTICEABLE AS EVER. THE FORD DEALERSHIP TOLD ME THAT FORD HAS A NEW SERVICE BULLETIN OUT, BUT HAS NOT ISSUED A FIX. THIS IS A SERIOUS ISSUE, AND I HOPE THAT WITH ALL THE DRIVING I DO, I DON'T GET A LOSS...

WHILE ATTEMPTING TO PASS ANOTHER VEHICLE I TRIED TO ACCELERATE TO GET UP ENOUGH SPEED. THE VEHICLE STARTED SHUDDERING VIOLENTLY AND LOST ALL POWER, MAKING IT IMPOSSIBLE TO MAINTAIN HIGHWAY SPEEDS FOR A FEW MINUTES. FOR THE NEXT FEW MINUTES ANY ATTEMPT AT ACCELERATION RESULTED IN MORE SHUDDERING FROM THE ENGINE. THIS ALSO HAPPENED A FEW MONTHS BEFORE AT THE EXACT SAME POINT ON THE HIGHWAY. I HAVE THE ECOBOOST ENGINE IN MY VEHICLE. *TR

FIRSTLY, WHILE DRIVING ALONG A 3 MILE STRAIGHT STRETCH OF ROAD I PULL OUT TO PASS A SLOWER VEHICLE. MY TRUCK ENGINE SHUT DOWN IN TO WHAT FORD DESCRIBES AS "LIMP HOME MODE" MID-PASS AND I HAD TO DECELERATE QUICKLY AND GET BACK IN TO MY LANE BEFORE A HEAD ON COLLISION OCCURRED. THERE WERE VEHICLES IN THE LANE THAT I HAD TO CUTOFF TO GET TO SAFETY.I HAD TO PULL OVER TO THE SIDE OF THE ROAD AND SHUT OFF THE VEHICLE THEN RE-START IT BEFORE THE CONDITION CLEARED UP. THIS SAME SCENARIO HAPPENED AGAIN IN SEPTEMBER OF 2012. THIS TIME I WAS DRIVING ALONG WITH MY CRUISE CONTROL SET TO 62 MPH WHEN FOR NO REASON THE VEHICLE WENT IN TO "LIMP HOME MODE" AGAIN. I HAD TO PULL OVER ONCE AGAIN AND STOP/START THE ENGINE. I WAS IN A FAIR AMOUNT OF TRAFFIC WHEN THIS OCCURRED AND...

WELL I PURCHASED THIS TRUCK A BRAND NEW 2012 FORD F-150 XLT SUPER CREW W/ 3.5L ECOBOOST ENGINE. THE TRUCK HAD 104 MILES WHEN I BOUGHT IT. AFTER A WEEK I STARTED TO NOTICE THAT THE TRUCK SHUDDER'S WHEN I ACCELERATE FROM A DEAD STOP AND IT ALSO SHUDDERS WHEN I COME TO A FULL STOP. FOR ABOUT A WEEK EVERY SINGLE DAY AND TIME I WOULD START AND STOP THE TRUCK WOULD SHUDDER. I THOUGHT THIS WAS BECAUSE THE ENGINE JUST NEEDED TO BREAK IN. WELL I AM GOING ON THE 4TH WEEK OF OWNING THIS TRUCK AND IT STILL OCCURS. THE SHUDDER THAT IS. THE SHUDDER ALSO OCCURS NOW WHEN I HAVE A COLD ENGINE START AND I PUT THE TRUCK IN REVERSE IT STARTS TO SHUDDER. I DO FEEL AS THE DRIVER IT HAS EFFECTED THE PERFORMANCE OF MY TRUCK. 854

THE TRUCK HAS A SHUTTER WHEN ACCELERATING. IT HAS A HESITATION ALL THE TIME IN THE ENGINE. IF I AM GOING UP A HILL AND RUNNING THE SPEED LIMIT, IT HAS A MAJOR HESITATION BEFORE IT WILL SHIFT GEARS TO GET ON UP THE HILL. THE GAS MILEAGE IS NOT AS GOOD AS IT CLAIMS TO BE EITHER. *TR

I HAD SLOWED DOWN TO EXIT OFF THE FREEWAY TO GET ON ANOTHER FREEWAY. WHEN I PUSHED THE ACCELERATOR, THE TRUCK STARTED TO SHUTTER, SHAKE, AND LOSE POWER. I TOOK MY FOOT COMPLETELY OFF THE ACCELERATOR AND LET THE TRUCK COAST A SHORT DISTANCE. WHEN I TRIED TO ACCELERATE AGAIN, THE TRUCK SEEMED FINE. IT DID THIS TWICE ON THE SAME DAY. I TOOK IT TO THE FORD DEALERSHIP AND THEY TOLD ME THE TRUCK WAS FINE. I HAVE AN ECO-BOOST V-6 ENGINE. *TR

WHILE DRIVING AT HIGHWAY SPEED, I HEARD A POP AND 'DING' SOUND BEFORE LOSING ALL ELECTRICAL ITEMS - DASH BOARD, HEAD LIGHTS, TAIL LIGHTS, BRAKE LIGHTS, TURN SIGNALS, ETC., BUT THE ENGINE WAS STILL OPERATING. I THEN FELT A GRINDING NOISE AND IMMEDIATELY EXITED THE HIGHWAY SAFELY TO PARK AT A GAS STATION. I TURNED OFF AND REMOVED THE KEY BUT THE ENGINE WAS STILL RUNNING. I WAS ONLY A FEW MILES FROM A FORD DEALERSHIP. I INSERTED THE KEY, TURNED IT TO THE ON POSITION AND TRIED TO PUT THE TRUCK INTO GEAR WHILE DEPRESSING THE BRAKE. THE TRANSMISSION BRAKE RELEASE WOULD NOT WORK. I CALLED ROADSIDE ASSISTANCE WHO SCHEDULED A TOW TO THE DEALERSHIP. I HAD TO CALL THE DEALERSHIP TO FIGURE OUT HOW TO TURN THE ENGINE OFF. THEY ADVISED THAT I SHOULD PULL THE FUEL PUMP RELAY FUSE WHICH DID STOP THE ENGINE. TO DATE, FORD...

MERGING ONTO INTERSTATE AT 50 MPH I ACCELERATED HARD TO MERGE INTO TRAFFIC. COMPLETE LOSS OF ACCELERATION NEARLY CAUSING AN ACCIDENT WITH A TRACTOR TRAILER BEHIND US. VIOLENT SHUDDERING OF ENTIRE VEHICLE, CHECK ENGINE LIGHT FLASHED AND THEN REMAINED ON. AFTER NEARLY A MINUTE OF FEATHERING THE ACCELERATOR, THE PROBLEM SUBSIDED AND ABILITY TO ACCELERATE WAS REGAINED. THIS HAD ALREADY HAPPENED ONCE ON THE SAME DRIVE AND A COUPLE IF TIMES PRIOR TO THIS INCIDENT. I DROPPED THE TRUCK OFF AT THE DEALER THIS AM AFTER DRIVING IT FOR TWO DAYS WITH THE CHECK ENGINE LIGHT ON. THEY SAID THEY WOULD CALL WITH AN UPDATE IN THE AFTERNOON, BUT WHEN 7PM ROLLED AROUND AND I HAD NOT YET HEARD FROM THEM I CALLED TO SEE WHAT WAS GOING ON AND WAS TOLD THAT THEY WERE WAITING FOR A REPLACEMENT INTERCOOLER AND TO CALL BACK IN THE MORNING AND SPEAK WITH...

VEHICLE WAS PURCHASED ON 3/16/13 AS A DEMO MODEL WITH 6300 MILES ON IT. MADE A LEFT TURN AND ACCELERATED TO MERGE INTO TRAFFIC ON 3/19/13 WHEN THE WHOLE VEHICLE SHUDDERED VIOLENTLY AND THE ENGINE LOST POWER RESULTING IN PEOPLE HAVING TO HIT THEIR BRAKES AND HONK AT US TO AVOID HITTING US. THE ENGINE CONTINUED TO BOG DOWN AS THE ACCELERATOR WAS PUSHED. I LET THE VEHICLE COAST TO ALMOST A STOP BEFORE THE SYMPTOMS WENT AWAY AND COULD DRIVE AS NORMAL. I LOOKED UP SYMPTOMS ON INTERNET AND FOUND MANY PEOPLE EXPERIENCING SAME SYMPTOMS WITH THIS NEW ECO-BOOST ENGINE BY FORD IN THEIR TRUCKS. IT SEEMS THAT THE INTERCOOLER CAN COLLECT CONDENSATION IN HUMID OR RAINY ENVIRONMENTS AND HAVE THAT WATER FORCED TO THE ENGINE WHEN THE ACCELERATOR IS PUSHED HARD CAUSING THE VEHICLE TO SHUDDER AND LOSE POWER. FORD HAS APPARENTLY IDENTIFIED THIS PROBLEM AND ISSUED A...

FULL THROTTLE PASSING. SEVERE ENGINE MISS. LOSS OF POWER. COULD NOT COMPLETE PASS. HAD TO PULL BACK IN LINE. SEAMS TO BE PROBLEM ON ECOBOOST V6 ENGINES. COLD CLIMATE HUMIDITY. POSSIBLE FIX SERVICE BULLETIN PARTS B O INTERMITTENT CANT PREDICT WHEN POWER LOSS WILL HAPPEN

WHEN ACCELERATING TO PASS ANOTHER CAR, THE VEHICLE SUDDENLY LOOSES POWER. AFTER ACCELERATING RAPIDLY TO GET ON THE FREEWAY AND RELEASING THE GAS PEDAL, THE CAR CONTINUES TO ACCELERATE. FORD SAID THERE IS A PROBLEM WITH THEIR INTERCOOLERS AND THEY HAVE BEEN ON BACKORDER FOR SEVERAL MONTHS. THIS IS A SAFETY ISSUE FOR ME AND MY FAMILY AND FORD TELLS ME TO CONTINUE TO DRIVE MY CAR WHILE I WAIT MORE MONTHS UNTIL THE PARTS ARE READY. *TR ## VIN FAILED ##

WHILE DRIVING ON FREEWAY AND TRYING TO PASS, VEHICLE STARTED SHAKING VIOLENTLY AND LOST POWER. ALSO WHEN PULLING OUT INTO TRAFFIC VEHICLE WHEN LOSE POWER AND ENGINE SHAKES. ENGINE LIGHT CAME ONA ND HAS REMAINED ON. VERY DANGEROUS SITUATIONS CONTINUE TO HAPPEN DAILY. FORD ECOBOOST SYSTEM HAS A PROBLEM, DEALERSHIP SAYS FORD IS AWARE BUT DOES NOT KNOW WHEN PARTS TO REPAIR MIGHT BE AVAILABLE. SAYS TO CONTINUE TO DRIVE. I AM CONCERNED A MAJOR ACCIDENT IS WAITING TO HAPPEN. THIS SEEMS TO BE SOMETHING FORD WAS AWARE OF WHEN SOLD THIS VEHICLE. *TR

WHILE TRAVELING AT HIGHWAY SPEED (COLD WINTER MORNING), WITH CRUISE CONTROL ON, STARTED TO CLIMB HILL, ENGINE BEGAN TO THROTTLE UP, THEN THE TRUCK BEGAN TO SHAKE VIOLENTLY, ENGINE LOST POWER. SHUT OFF CRUISE CONTROL AND COASTED ONTO SHOULDER. WAS ABLE TO SLOWLY ENGAGE THROTTLE AND CONTINUE, BUT ANY INCREASE IN THROTTLE ABOVE "GENTLE" WOULD BRING ON THE SHUDDER AND POWER LOSS. ENGINE LIGHT FLASHED AND STAYED LIT FOR NEXT 20 MINUTES. EXPERIENCED SIMILAR SCENARIO LATER THE SAME DAY. TOOK TO DEALER. DEALER INDICATED CHARGED AIR COOLER WORKS "TOO WELL". COOLS AIR SO MUCH THAT CONDENSATION FORMS AND CAUSES THE ISSUE. DEALER INDICATED A TECHNICAL SERVICE BULLETIN HAD BEEN ISSUED ON THE PROBLEM. NEED NEW CAC AND SHIELD.
