2011 FORD F-150 Engine Problems

ENGINE LOSSES POWER AND SHUDDERS BADLY WHEN TRYING TO ACCELERATE TO OVER TAKE. ENGINE LIGHT COMES ON AND WHEN DIAGNOSED SAYS MISFIRE NUMBER 4 CYLINDER, CHECKED AND INSTALLED NEW PLUG AND COIL AFTER 50 MILES THE SAME PROBLEM AND DEALER SAYS THEY CAN NOT FIX ISSUE. THIS IS THE THIRD TIME THIS HAS HAPPENED AFTER COILS HAVE BEEN REPLACED. THE REPLACEMENT COILS WERE OEM MOTORCRAFT UNITS. IN READING ABOUT THIS PROBLEM IT APPEARS THAT THIS POWER UNIT HAS A LARGE NUMBER OF COMPLAINTS AND ISSUES.

TL* THE CONTACT OWNS A 2011 FORD F-150. THE VEHICLE STALLED WITHOUT WARNING WHILE DRIVING 40 MPH. THE VEHICLE RESUMED NORMAL FUNCTION AFTER RESTARTING THE ENGINE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE FAILURE WAS UNABLE TO BE DETERMINED; HOWEVER, THE DEALER DISCOVERED THAT THE COOLANT SYSTEM WAS NOT SEPARATING THE SLUDGE CAUSING THE SLUDGE TO PENETRATE THE ENGINE AND ACTIVATING THE VEHICLE LIMP MODE. THE CONTACT STATED THAT THE VEHICLE WAS NOT REPAIRED. THE CONTACT STATED THAT HE WOULD INSTALL AN OIL SEPARATION DEVICE TO THE VEHICLE INDEPENDENTLY. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 31,263.

TL* THE CONTACT OWNS A 2011 FORD F-150. WHILE DRIVING APPROXIMATELY 45 MPH, THE CHECK ENGINE WARNING LIGHT ILLUMINATED. IN ADDITION, WHEN THE VEHICLE WAS STARTED, THERE WAS AN ABNORMAL NOISE UNDER THE HOOD OF THE VEHICLE INTERMITTENTLY. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE TIMING CHAIN FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 65,000. UPDATE 01/13/16 MA *CN

I HAVE TAKEN MY TRUCK BACK WHILE UNDER WARRANTY THEY NEVER COULD FIND ANYTHING, BUT IT HAD A MIS WHEN I WOULD GET ON THE GAS. IT NEVER REALLY STALLED OUT BUT WOULD JUMP PRETTY GOOD, NEVER SEEMED TO RUN REALLY SMOOTH. I KEEP TELLING THE DEALER TO PLEASE CHECK OUT. I GIVE UP AND KEEP DRIVING THE TRUCK AND NOW THAT ITS OUT OF WARRANTY THEY FIND THAT ITS SOMETHING TO DO WITH VARIABLE CAMSHAFT AND GOING TO COST $4,400.00 TO FIX NOT COUNTING THE OTHER THINGS I HAVING TO PAY FOR THAT WAS TAKEN BACK WHILE UNDER WARRANTY. FROM THE DAY I BOUGHT THE TRUCK WATER HAS BEEN IN THE PASSENGER FLOOR BOARD AND NOW THEY TELL ME, ITS THE HEATER BOX NEED REPLACE AT A COST OF $1,400.00 STRANGE THEY CAN FIND ALL THIS NOW THAT I HAVE TO PAY FOR IT. MY TRUCK HAD TO BE...

UNDER ACCELERATION OR TRYING TO PASS A VEHICLE LOSS OF POWER HAS BEEN OCCURING. TRYING TO ACCELERATE INTO INTERSTATE FROM ON RAMP HAVE HAD POWER LOSS AND VEHICLE LOSES ALL ACCELERATION.

WHILE ACCELERATING ON TO THE HIGHWAY ON A CLEAR, WARM, SUNNY DAY; THE TURBO ENGAGED AND THE TRUCK BEGAN TO SHUDDER. THERE WAS IMMEDIATE DECELERATION AND THE CHECK ENGINE LIGHT BEGAN TO FLASH. AFTER EASING UP ON THE THROTTLE AND COASTING, THE LIGHT TURNED OFF AND THE TRUCK BEGAN OPERATING NORMALLY. THIS OCCURRED WITHIN 1-MILE OF TRAVEL. I WAS UNABLE TO REPLICATE THE ISSUE ON THE REMAINDER OF THE DRIVE. THIS IS A MAJOR SAFETY CONCERN AS THE SPEED OF THE VEHICLE DROPS DRAMATICALLY IN A SHORT DISTANCE AND THE VEHICLE IS UNABLE TO RECOVER RAPIDLY, LEAVING THE VEHICLE'S OCCUPANTS SUSCEPTIBLE TO POTENTIALLY CATASTROPHIC ACCIDENTS ON THE ROADWAY.

ECO BOOST ENGINE. PROBLEM HAS OCCURRED SEVERAL TIMES. PROBLEM HAS OCCURRED WHEN RAPIDLY PULLING AWAY FROM A TOLL BOOTH AFTER SEVERAL HOUR OF CONTINUOUS INTERSTATE DRIVING IN THE RAIN (OCCURRED 10/2013 AND 10/2015). PROBLEM HAS OCCURRED WHEN TRYING TO PASS ANOTHER VEHICLE ON A 2 LANE ROAD UNDER THE SAME TYPE OF RAINY CONDITIONS (OCCURRED 10/2015). ENGINE WILL SHUDDER AND GO INTO LIMP MODE. TRUCK WAS TAKEN 2 YEARS AGO TO THE FORD DEALERSHIP FOR REPAIR OF THIS PROBLEM. TWO EVENTS OCCURRED THIS PAST WEEK UNDER RAINY CONDITIONS. TRUCK IS NOW OUT OF WARRANTY AND STILL NOT FIXED.

ON OCTOBER 26 AT AROUND 1230 PM I WAS GOING THE SPEED LIMIT 60 MPH. ON LOOP 250.ALL OF A SUDDEN MY TRUCK STARTS JERKING REALLY HARD. I LET GO OF THE GAS AND LOOKED AT THE DASH THE SPEEDOMETER AND GEARS WERE GOING CRAZY UP AND DOWN. I WAS ABLE TO PULL OVER SAFE CAUSE IT WAS LUNCH HOUR LOTS OF TRAFFIC. TURNED TRUCK OFF WAS SHAKING, SCARED AND VERY UPSET. CALLED MY HUSBAND TOLD HIM WHAT HAPPENED ASKED IF I WAS OK I SAID YES BESIDES VERY SHAKEN UP. HE SAID IT MIGHT BE THE TRANSMISSION OR TCM . STARTED THE TRUCK WENT SLOW TO DEALERSHIP. THIS WAS VERY TRAUMATIC EXPERIENCE I'M THINKING WHAT IF THE GEARS WOULD'VE GOTTEN STUCK OR REVERSE AND I WOULD'VE ROLLED. PLEASE LOOK INTO THIS CAUSE IT WAS VERY SCARY.

ON OCTOBER 26 WAS ON MY WAY TO WORK I WAS ON LOOP 250 WHICH IS 60 MPH. GOT ON THE LOOP WAS APPROACHING AN OVER PASS WHEN SUDDENLY WITH NO WARNING LIGHTS IT STARTS JERKING, A PULLING, SHAKING. TOOK FOOT OFF GAS PEDAL LOOKED AT DASH NO WARNING LIGHTS ON BUT THE SPEEDOMETER AND GEARS ON DASH WERE GOING CRAZY GOING UP AND DOWN. SLOWING DOWN APPLYING THE BRAKE SLOWLY CAUSE LOTS OF TRAFFIC BEHIND AND I FRONT OF ME. I WAS SHAKING AND VERY UPSET FINALLY PULLED OVER AND TURNED TRUCK OFF CALLED MY HUSBAND I TOLD HIM WHAT HAPPENED. HE ASKED IF THE TRUCK TURNED ON IT DID I TOOK IT TO DEALERSHIP GOING VERY SLOW. MY HUSBAND MET ME THERE AND I TOLD THEM WHAT HAPPENED. I WAS VERY SHAKEN UP ALMOST IN TEARS. THIS IS A SAFTEY ISSUE IM LIKE WHAT IF THE TRUCK WOULD...

REFERENCE 2011 FORD F-150 ECOBOOST: WAS DRIVING ON THE EXPRESSWAY AT HIGHWAY SPEEDS AND SLOWED TO ABOUT 30MPH FOR HEAVY TRAFFIC. WHEN I BEGAN TO INCREASE SPEED TRUCK BEGAN TO SHUDDER AND THE "CHECK ENGINE" LIGHT CAME ON. STARTED TO PULL TOWARD THE RIGHT SHOULDER FROM FAR LEFT LANE, WHEN THE ENGINE STALLED COMPLETELY AND HAD TO ROLL WITHOUT POWER TO THE SHOULDER. THE TRUCK/ENGINE CONTINUED TO LIMP TO THE DEALER. THIS IS THE 8-9TH TIME I'VE EXPERIENCED THIS PROBLEM AND THE TRUCK HAS LEFT ME AND MY KIDS IN A DANGEROUS SITUATION ON THE INTERSTATE. TO ADD INSULT TO INJURY, EACH TIME THIS HAPPENED, THE DEALER HIT ME WITH THE $100 DIAGNOSTIC FEE EVEN THOUGH THE TRUCK IS UNDER WARRANTY. ALL TSB'S HAVE BEEN DONE AND NOTHING HAS FIXED THE PROBLEM AND ACTUALLY HAS MADE MATTERS WORSE BY THE DEALER "REFLASHING" THE TRUCK AND KILLING THE AVG. MPG. IT...

THE LOW OIL PRESSURE LIGHT COMES ON WHEN THE OIL IS FULL. SAYING OIL PUMP LOW PRESSURE. THIS STARTED ABOUT 4 WEEKS AGO. IT SEEMS TO ONLY DO THIS WHEN RPM'S ARE 1200 AND BELOW.

WHILE DRIVING ON INTERSTATE MY VEHICLE STARTED TO MISS FIRE AND LOSE POWER. I WAS HAULING A HORSE TRAILER GOING APPROXIMATELY 60 MPH WITH LARGE 18 WHEEL VEHICLES WHEN THE ENGINE STARTED MISS FIRING AND LOOSING POWER. WAS ABLE TO GET OFF INTERSTATE AND FIND A LOCAL FORD DEALERSHIP. WHILE DRIVING TO FORD DEALERSHIP THE CHECK ENGINE LIGHT CONTINUED TO FLASH, I FINALLY LOST ALL POWER AND THE TRUCK SHUDDERED AND FLASHERS AUTOMATICALLY WENT ON, WAS ABLE TO GET TO DEALER SHIP AND WAS DIAGNOSED WITH BAD #4 COIL. THIS WAS REPLACED UNDER WARRANTY WITH A $100 DEDUCTIBLE AND 6 DAYS LATER SAME THING HAPPENED, AGAIN WHILE HAULING HORSE TRAILER ON INTERSTATE, SAME ISSUES WITH LOOSING POWER, CHECK ENGINE LIGHT FLASHING AND TRUCK SHUDDERED. AGAIN WAS LUCKY ENOUGH TO MAKE IT TO A LOCAL FORD DEALERSHIP, THIS TIME #6 COIL WAS DIAGNOSED AS BEING BAD. THIS WAS CHANGED UNDER WARRANTY...

ACCELERATED TO MERGE ONTO THE HIGHWAY. TRUCK SUDDENLY LOST ALL ACCELERATION AND BEGAN TO SHAKE. ENGINE LIGHT CAME ON. DECELERATION WAS AS SUDDEN AS IF I HAD SLAMMED ON MY BRAKES. COASTED TO THE SIDE OF THE HIGHWAY AND TURNED OF THE TRUCK. AFTER A FEW MINUTES OF ME SHAKING, I RESTARTED THE TRUCK. ENGINE LIGHT WAS STILL ON, BUT TRUCK DROVE NORMALLY AS LONG AS I "CREPT" UP TO SPEED.

I WAS DRIVING ON A HIGHWAY, TOWING A TRAILER IN AN AREA OF HEAVY CONGESTION. WHEN I ATTEMPTED TO ACCELERATE, THE VEHICLE BEGAN TO SHAKE VIOLENTLY AND LOST POWER. THE ENGINE WAS APPARENTLY MISFIRING AND WAS RUNNING VERY ROUGH. THE CHECK ENGINE LIGHT CAME ON AND I PULLED OFF THE HIGHWAY. WHEN I STOPPED, I PUT THE VEHICLE IN NEUTRAL, BUT LEFT IT RUNNING. THE CHECK ENGINE LIGHT WENT OFF AND THE ENGINE SEEMED TO RUN FINE. BUT EVER SINCE THEN, WHENEVER I ATTEMPT TO ACCELERATE, THE VEHICLE SHAKES VIOLENTLY AND WON'T ACCELERATE. THIS IS GOING TO CAUSE AN ACCIDENT! I CHECKED AROUND THE INTERNET AND THIS SEEMS TO BE A COMMON PROBLEM WITH THIS VEHICLE, BUT WHEN I CALLED FORD THEY TOLD ME I WOULD HAVE TO PAY TO HAVE A LOCAL DEALER RUN DIAGNOSTICS. THEY ADMITTED THAT THEY HAD ISSUED A TECHNICAL SERVICE BULLETIN TO THE DEALERS ON...

APPROXIMATELY 9 TO 10 TIMES I HAVE EXPERIENCED LOSS OF POWER SHUTTERING MISFIRES AND BACKFIRING ONLY TO FIND FOULED SPARK PLUGS I HAVE REPLACED THE SPARK PLUGS APPROXIMATELY EIGHT TIMES IN 10,000 MILES DUE TO THIS CONDITION ON THIS FORD ECO-BOOST ENGINE. ALL TSB'S HAVE BEEN COMPLETED ON THE TRUCK YET I STILL EXPERIENCE THIS ENGINE PROBLEM

WE DROVE THE VEHICLE 6 HOURS WITH THE AIR CONDITIONER ON.... PARKED IT - STARTED IT AGAIN ABOUT 2 HOURS LATER. THE VEHICLE REVVED VERY HIGH, BARELY CHUGGED AS WE DROVE AND THEN THE YELLOW "WRENCH" LIGHT CAME ON - INDICATING TRANSMISSION ISSUES AS WELL AS A "LIMP HOME" MODE. WE WERE UNABLE TO DRIVE THE VEHICLE AT THAT POINT AND HAD TO KEEP IT PARKED.... AFTER DOING SOME RESEARCH - WE DISCOVERED THAT CONDENSATION HAD GOTTEN INTO SOME SORT OF CONDENSER AND CAUSED THE ECO-BOOST ENGINE TO MISFIRE AND ESSENTIALLY MALFUNCTION.

WHEN THE TURBO BOOST IS 11PSI MISFIRING BEGINS - NO AFTER MARKET ENGINE PROGRAMMING. IF TURBO DEMAND IS NOT REDUCED, OR IS INCREASED THE ENGINE LIGHT WILL COME ON AND THE TRANSMISSION WILL BE DISENGAGED - 'LIMP MODE.' ON THE DATE CITED, THIS HAPPENED NO LESS THAT 3 TIMES. LOCAL HUMIDITY WAS 50-70%, AS I RECALL, AND THERE WAS NO RAIN. I HAVE EXPERIENCED THIS MULTIPLE TIMES WITH LOCAL HUMIDITY NOTED AT 50 %. MY EXPERIENCE IS THAT THE MISFIRING WILL OCCUR ANYTIME TURBO PSI EXCEEDS 11, WHETHER TOWING OR NOT, THOUGH TOWING WILL BE MORE APT TO ENCOUNTER 11PSI. MY TRAILER IS WITHIN ALL TOW LOAD LIMITS FOR MY TRUCK, AXLES AND TONGUE, PER FORD'S RV & TRAILER TOWING GUIDE. MY FIRST EXPERIENCE WITH THE TRUCK GOING LIMP WAS JUNE OF 2014. I PULLED THE TRUCK TO THE SHOULDER NEXT TO A GUARD RAIL AND CALLED FOR TOWING. THE...

MY 2011 FORD F-150 ECOBOOST 3.5 WAS IDLING AT A RED LIGHT THEN SUDDENLY BEGAN A VERY ROUGH IDLE. THIS WENT ON FOR ABOUT TWENTY MINUTES ( ON AND OFF) THEN CLEARED UP . WE TOOK THE TRUCK TO THE LOCAL DEALERSHIP AND HAD THEM LOOK AT IT . THEY DID A SERVICE ORDER AND CAME UP WITH NOTHING WRONG. WE TOOK THE TRUCK HOME AND THE PROBLEM REMAINED. THE TRUCK WAS TAKEN BACK 4 OR 5 MORE TIMES FOR THE SAME PROBLEM AND THE DEALERSHIP COULD NEVER FIND A PROBLEM. WHILE DRIVING THE VEHICLE ON THE HIGHWAY AND ATTEMPTING TO PASS SLOWER MOVING CARS, THE TRUCK HESITATED AND SPUTTERED WHEN THE GAS PEDAL WAS DEPRESSED. A MONTH AGO THE ENGINE STARTED MAKING A NOISE AFTER A COLD START AND THEN LATELY A LOUDER NOISE FROM TIME TO TIME IN THE PASSENGER SIDE FRONT AREA OF THE VALVE COVER. THEN...

TL* THE CONTACT OWNS A 2011 FORD F-150. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 50 MPH, THE STEERING WHEEL WAS HARD TO TURN AND A WARNING DISPLAYED ON THE PANEL THAT READ 'SERVICE ADVANCE TRAP". THE VEHICLE WAS TAKEN TO THE DEALER. THE TECHNICIAN WAS NOT ABLE TO DIAGNOSE THE FAILURE. IN ADDITION, THE CONTACT STATED THAT WHEN ATTEMPTING TO PASS ANOTHER VEHICLE, THE ACCELERATOR PEDAL WAS ACTIVATED AND THERE WAS LOSS OF ACCELERATION AS THE CHECK ENGINE LIGHT FLASHED ON AND OFF. THE FAILURE RECURRED MULTIPLE TIMES. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 57,000.

THE ENGINE LOST POWER, THE AIRCONDITIONING SHUT OFF. WHEN TRYING TO ACCELERATE, THE TRUCK SHUDDERED HARD. WHEN THE TRUCK WAS BROUGHT TO A STOP, IT WAS LIKE EVERYTHING RESET. THE ENGINE WOULD ACCELERATE CORRECTLY, THE AIR CONDITIONING CAME BACK ON, AND THERE WAS NO SHUDDER.. THE FORD HOUSE SAID THERE WERE NO CODES STORED TO IDENTIFY THE PROBLEM. THEY RECOMMENDED A $1100.00 TUNEUP.

THE ENGINE STALLED (SEVERER LOSS OF POWER) AS I TRIED TO OVERTAKE/PASS ANOTHER VEHICLE. THIS HAS HAPPENED NUMEOUS TIMES & TYPICALLY OCCURS DURING HUMID/RAINING WEATHER. I HAVE TAKEN THE TRUCK TO THE DEALERSHIP SEVERAL TIMES BUT THEY HAVE YET TO RESOLVE THE ISSUE. IT IS MY UNDERSTANDING THAT FORD IS VERY AWARE OF THE PROBLEM AND HAS ISSUED SEVERAL TECHNICAL SERVICE BULLETINS BUT, THE PROBLEM STILL EXIST. FORD SHOULD BE HELD RESPONSIBLE FOR THIS SAFETY ISSUE & FORCED TO RECALL AND REPAIR THESE TRUCKS BEFORE SOMEONE IS SERIOUSLY INJURED OR KILLED.

WHEN ACCELERATING AND APPROACHING FREEWAY SPEED, ENGINE STUMBLED, PREVENTING ACCELERATION. I LET OFF THE ACCELERATOR AND PROBLEM DIDN'T OCCUR AGAIN. I REPORTED THIS TO THE DEALER, BUT THEY STATED THAT SINCE THE VEHICLE DID NOT REGISTER A CODE THERE WAS NOTHING THEY COULD DO. I HAVE SINCE HAD THIS HAPPEN AGAIN ON JULY 17 & 18, 2015, BUT THIS TIME THE ENGINE LIGHT DID COME ON, SO I'M ASSUMING IT DID REGISTER A CODE. ON JULY 17, IT WAS A CLEAR DRY DAY, THE FOLLOWING DAY IT HAPPENED AGAIN, BUT IT WAS RAINING ALL DAY. ONCE ON THE FREEWAY, WHENEVER I STEPPED ON THE ACCELERATOR, EVEN WHEN AT FREEWAY SPEED, THE ENGINE WOULD STUMBLE AND BARELY ACCELERATE. I'VE CONTACTED THE DEALER AND SCHEDULED AN INSPECTION FOR JULY 29, 2015. THE VEHICLE CURRENTLY HAS 47000 MILES. I'VE TALKED TO FORD CUSTOMER SERVICE AND I AM BEING TOLD THIS IS NOT A...

GOING UP HIGHWAY @ 55MPH. PULLED AROUND A VEHICLE TO PASS. ONCE, I WAS IN THE ONCOMING TRAFFIC THE ENGINE SUDDENLY LOST POWER, CHUGGED, AND WAS STUMBLING OVER ITSELF. I THEN GOT BACK BEHIND THE VEHICLE I WAS PASSING. THE 4 PASSENGERS AND I WERE ALL QUIET AND THEN FREAKED OUT. AFTER A WHILE WE PULLED OUT AND ACCELERATED TO GO UP ROAD AGAIN, TRUCK DOGGED OUT. WE HAD NO CLUE WHAT WAS HAPPENING, BUT EVERYONE WAS FREAKED OUT. WE CALLED BIRTHDAY PARTY DESTINATION TO TELL THEM WE HAVE VEHICLE TROUBLE AND CAN'T MAKE IT. DROVE IT DOWN HILL ALL THE WHILE WORRIED THE ENGINE WAS GOING TO BLOW. DROVE IT DIRECTLY TO DEALERSHIP WHO STATED THEY HAD NO CLUE AND DID NOT WANT US TO LEAVE IT THERE. SAID SET UP APPT. 7-10 DAYS OUT. PARKED IT UNTIL APPT. THEN THEY REPLACED ALL SPARK PLUGS. WE ALSO HAVE HAD...

ON JUNE 12, 2015 I WAS DRIVING SOUTH ON I 75 IN GEORGIA ON MY WAY TO FLORIDA. I HAD THE CRUISE SET AT AROUND 80 MPH AND CAME UP TO A SLOWER MOVING VEHICLE. I TAPPED THE BREAKS TO CANCEL THE CRUISE CONTROL AND THEN PRESSED THE ACCELERATOR TO PASS THE SLOWER MOVING VEHICLE. AS I PRESSED THE ACCELERATOR THE TRUCK BEGAN TO SHAKE QUITE VIOLENTLY AND THE ENGINE LIGHT ON THE DASH BEGAN TO FLASH. MY TRUCK SLOWED TO ABOUT 55 OR 60 MPH. I ATTEMPTED TO ACCELERATE MY TRUCK FOR A SECOND TIME BUT I RECEIVED NO RESPONSE FROM THE THROTTLE. I PULLED THE TRUCK IN TO THE FAR RIGHT LANE AND ATTEMPTED SEVERAL MORE TIMES TO GET THE TRUCK TO ACCELERATE BUT WITH NO RESPONSE. ABOUT ONE OR TWO MILES LATER I FELT A "KICK" AND THE TRUCK WAS BACK TO NORMAL LIKE NOTHING HAD EVER...

I WAS DRIVING TO WORK THIS VERY HUMID MORNING MERGING ONTO THE INTERSTATE IN MY 2011 ECOBOOST F-150. AS I ACCELERATED TO MERGE, MY RPM'S WENT UP BUT MY SPEED ACTUALLY DROPPED JUST AS VEHICLES WERE COMING IN AT A HIGH RATE OF SPEED BEHIND ME. I LET OFF ON THE THROTTLE AND AGAIN PRESSED DOWN ON THE ACCELERATOR WITH THE SAME RESULT. I WAS TRAPPED BETWEEN CARS AND CAUSED ONE CAR TO SWERVE DANGEROUSLY ON THE HIGHWAY. THANKFULLY THERE WAS NOT AN ACCIDENT, BUT CERTAINLY GOT MY FILL OF MIDDLE FINGERS FROM UPSET MOTORISTS AND LUCKED OUT NOT BEING THE VICTIM OF ROAD RAGE MY TRUCK CAUSED. A MINUTE OR SO LATER THE VEHICLE BEGAN TO OPERATE AS NORMAL. AFTER RESEARCHING ONLINE THIS MORNING I REALIZED THIS IS EXTREMELY COMMON WITH THIS ENGINE. I CONTACTED BOTH MY LOCAL DEALER AND FORD CORPORATE ONLY TO BE TOLD THERE IS NO...

WHILE TRYING TO SPEED UP THE ENGINE LAGS OUT CAUSING THE VEHICLE TO MISFIRE MAKING IT IMPOSSIBLE TO ACCELERATE AND CAUSES THE VEHICLE TO SHAKE. MY ECOBOOST ONLY EXPERIENCES THIS ISSUE AT HIGH SPEEDS WHICH IS AN INCOVIENCE ON THE HIGHWAY .

WHILE TRAVELING A LONG DURATION AT A CONSISTENT MPH, LOW RPM, AND LOW TURBO BOOST PRESSURE I BEGAN TO CLIMB A HILL WHERE MORE ACCELERATION WAS NEEDED TO MAINTAIN MPH. AT TIME THE VEHICLE RAPIDLY SLOWED, ENGINE LIGHT CAM ON, TRIED TO ADD THROTTLE TO STAY OUT OF THE WAY OF APPROACHING TRAFFIC BUT JUST CONTINUED TO SLOW. THIS HAPPENED WHILE TRAVELING FROM LAS VEGAS NEVADA TO RENO NEVADA. I REPLACED THE IGNITION COILS AND THAT SOLVED THE PROBLEM ONLY TO HAVE IT HAPPEN AGAIN IN LESS THAN 5K MILES IN THE SAME DRIVING CONDITIONS

DRIVING WITH MY DAUGHTER, I TOOK A CORNER AT APPROXIMATELY 25MPH AND THEN PUSHED THE GAS TO GET MOVING AND LOST ALL POWER TO THE ENGINE, TRIED PUTTING IN LOW GEAR BUT TO NO PREVAIL, TRIED AGAIN SHIFTING BACK TO DRIVE WITH NOTHING HAPPENING. AT THIS TIME WE ARE STUCK IN TRAFFIC WITH PEOPLE FLYING BY US AND NOTHING I CAN DO. FINALLY I SHUT OFF THE ENGINE AND LET IT SIT FOR A MINUTE. RESTARTED AND THE CHECK ENGINE LIGHT CAME ON BUT RAN WELL ENOUGH FOR US TO GET HOME. I HAVE NOT EXPERIENCED THIS BEFORE AND LUCKILY WE WERE CLOSE TO HOME. IF IT HAPPENED ONCE IT WILL HAPPEN AGAIN AND PROBABLY NOT THE SAME LUCK I HAD THIS TIME. SOMETHING NEEDS TO BE DONE ABOUT THIS PROBLEM. THANK YOU

FX2 3.5L V6 ECOBOOST: WAS DRIVING APPROX. 65 AND HAD TO QUICKLY ACCELERATE TO PASS. THE TURBOS STARTED TO KICK IN AND SUDDENLY THE ENGINE BEGAN TO SHUDDER AND MISFIRE. CHECK ENGINE LIGHT CAME ON AND THEN WENT OFF. PROBLEM OCCURS DURING ANY SUDDEN ACCELERATION.

MY ECOBOOST ENGINE STALLED DURING ACCELERATION WHILE ATTEMPTING TO PASS ON A 2 LANE ROAD. THIS PUT ME AND MY FAMILY IN A VERY DANGEROUS SITUATION WHERE I WAS IN THE OPPOSING LANE WITH NO POWER. I HAVE ATTEMPTED TO HAVE THIS FIXED AT THE DEALER MORE THAN 5 TIMES. ONE DEALER ACTUALLY PUT IN A NEW SENSOR ABOUT 6 MONTHS AGO BUT THIS HAS FAILED TO FIX THE ISSUE. THIS IS A WELL KNOWN PROBLEM WITH THIS ENGINE YET FORD REFUSES TO FIX IT.

MY F150 ECOBOOST STALLED TWICE IN THE RAIN WHILE TRYING TO PASS ANOTHER CAR. THE TRUCK LOST ALL POWER WHILE I WAS ATTEMPTING TO PASS A VEHICLE IN HEAVY TRAFFIC. THIS HAPPENED ON I20. THE ENGINE FAILED A COUPLE YEARS BACK IN RAIN AND FORD INSTALLED A SHROUD OVER THE INTERCOOLER. AFTER REPORTING THE SECOND PROBLEM TO THE LOCAL DEALER, FORD INSTALLED A MODIFIED "NEW" SHROUD ON THE INTERCOOLER. THE GOVT PREMATURELY CLOSED THE INVESTIGATION OF F150 ECOBOOST ENGINES THAT HAVE A MAJOR FLAW THAT AFFECT VEHICLE PERFORMANCE. INSTALLING A MODIFIED SHROUD TO FIX A SERIOUS SAFETY ISSUE IS NOT A SOLUTION. PLEASE REOPEN THE INVESTIGATION FOR THE FORD F150 OWNERS THAT HAVE THE ECOBOOST ENGINE. *TR

VEHICLE LOST ACCELERATION WHEN TRYING TO PASS. ENGINE LIGHT CAME ON AND ENGINE STARTED TO SHAKE. I HAD TO TURN VEHICLE OFF AND RESTART. THIS NOW OCCURS ANYTIME I ATTEMPT TO ACCELERATE... *TR

I HAD BEEN DRIVING IN THE RAIN FOR APPROXIMATELY 3 HOURS. EXITED OFF THE INTERSTATE AND ATTEMPTED TO ACCELERATE AND THE TRUCK BOGGED DOWN, MISFIRING AND ALMOST CUTTING OFF. THIS IS A KNOWN PROBLEM BY FORD AND THEY HAVE ISSUED A TECHNICAL SERVICE BULLETIN. I UNDERSTAND THAT THERE IS AN ON-GOING INVESTIGATION TO DETERMINE IF THIS IS GOING TO BE A RECALL. THIS HAPPENED PREVIOUSLY WHEN I WAS ATTEMPTING TO PASS SOMEONE AND IT ALMOST CAUSED AN ACCIDENT. I TOOK IT INTO THE FORD DEALER WHERE I BOUGHT THE VEHICLE LAST YEAR AND THEY APPLIED THE FIX IN ACCORDANCE TO THE TECH BULLETIN BUT OBVIOUSLY THAT HAS NOT CORRECTED THE ISSUE. *TR

I WAS DRIVING AT HIGHWAY SPEED AND TRIED TO ACCELERATE QUICKLY TO PASS SOMEONE AND THE TRUCK HAD MAJOR HESITATION AND SHUDDERING. CONTINUES TO DO THIS ANYTIME YOU TRY TO RAPIDLY ACCELERATE. *TR

I WAS TRAVELING 45 MPH ON DRY ROADS/GOOD VISIBILITY/GOOD WEATHER IN 6TH GEAR WHEN WITHOUT WARNING THE TRANSMISSION SHIFTED FROM 6TH GEAR AND FINALLY ENDED IN 1ST GEAR - DURING THIS TIME THE ENGINE RPMS EXCEEDED 6000 RPMS - I IMMEDIATELY SHIFTED INTO NEUTRAL IN ORDER TO REDUCE THE ENGINE RPM. NEEDLESS TO SAY CONTROLLING THE VEHICLE WHEN THIS OCCURRED WAS A MAJOR SAFETY CONCERN. I THEN SHIFTED FROM NEUTRAL TO DRIVE AND ALL WAS WELL. LAST SUNDAY AFTER CHURCH THE TRANSMISSION WOULD AT FIRST NOT SHIFT FROM 1ST AND THEN WENT TO 5TH GEAR AND REMAINED IN 5TH GEAR TILL I PUT THE TRANSMISSION IN NEUTRAL AND THEN BACK INTO DRIVE. THIS EVENT HAS OCCURRED 4 TIMES THIS FAR.ALWAYS WHEN THE ENGINE AND TRANSMISSION ARE COLD!!! *TR

LOSS OF POWER. MISSFIRE. ENGINE LIGHT CAME ON AND WOULD NOT GO OFF. ECOBOOST 3.5 V6. MOISTURE PROBLEM GETTING IN TO CAUSE PROBLEMS. TURBO COOLER PROBLEM. TRUCK IS IN SERVICE NOW ON DATE ABOVE. *TR

FOLLOW UP TO COMPLAINT LISTED BELOW (BEGINNING WITH SUMMARY): IT SHOULD BE NOTED THAT THIS INCIDENT DID NOT OCCUR IN HUMID OR RAINY CONDITIONS. THIS INCIDENT DID NOT OCCUR WHILE TRAVELING AT HIGHWAY SPEED OR WIDE OPEN THROTTLE. THIS INCIDENT OCCURRED WHILE STARTING FROM A COMPLETE STOP UNDER LIGHT ACCELERATION TURNING LEFT ACROSS TRAFFIC. VEHICLE LOST ALL POWER AND WOULD NOT MOVE. PUSHING THE GAS PEDAL DID INCREASE ENGINE RPM BUT VEHICLE WOULD NOT MOVE. THE BEHAVIOR EXHIBITED BY THE VEHICLE SOUNDS VERY SIMILAR TO THE CONDENSATION PROBLEM I HAVE BEEN MADE AWARE OF WITH THE 3.5 V6 ECOBOOST. HOWEVER NONE OF THE CIRCUMSTANCES FORD CLAIMS CAUSES THE ISSUE EXISTED. THIS IS AN EXTREMELY DANGEROUS CONDITION. WEATHER WAS APPROXIMATELY 15 DEGREES AND SUNNY. I HAVE EXPERIENCED THE PROBLEM WHEN THE VEHICLE HAS BEEN COLD AND AFTER IT HAS BEEN RUNNING FOR A WHILE. SUMMARY: WHILE ATTEMPTING TO CROSS ONCOMING TRAFFIC...

I WAS ACCELERATING TO FREEWAY SPEED WHEN MY TRUCK BEGAN TO SHAKE AND MY ENGINE WAS NOT ALLOWING ME TO SPEED UP. IT FELT LIKE DRIVING OVER A WASHBOARD. THE ENGINE LIGHT BEGAN TO FLASH AND CONTINUED TO DO SO UNTIL I PULLED OVER AND STOPPED THE VEHICLE. THE ENGINE LIGHT STOPPED AND I WAS ABLE TO CONTINUE ON HOME. I TOOK IT TO THE DEALER THE FOLLOWING MORNING AND THEY REPLACED THE FAULTY SPARK PLUGS. THIS SAME ISSUE HAS NOW OCCURRED 3 TIMES IN LESS THAN 3 MONTHS. THE DEALER HAS NOW REPLACED THESE SPARK PLUGS 3 TIMES, TWICE OF WHICH THE ENTIRE SET OF SPARK PLUGS WERE REPLACED. I AM CONCERNED OVER THIS SAFETY ISSUE SINCE IT ALWAYS OCCURS AS I AM DRIVING AND SPEEDING UP TO GET ON THE FREEWAY. *TR

WHILE ATTEMPTING TO CROSS ONCOMING TRAFFIC LANES TO ACCESS INTERSTATE VEHICLE BEGAN TO MOVE THEN SUDDENLY LOST ALL POWER. RPM'S WENT UP TO 4000 RPM BUT VEHICLE WOULD NOT MOVE. VEHICLES WERE APPROACHING IN EXCESS OF 50MPH. I MANAGED TO BARELY AVOID BEING STRUCK BY ONCOMING TRAFFIC AND PULLED TO SIDE OF RAMP. VEHICLE THEN BEGAN TO MOVE AGAIN. TOOK VEHICLE IN FOR SERVICE. DEALERSHIP PERFORMED TWO FIXES INVOLVING SOME FORM OF AIR DAM. ON 02/24 VEHICLE DID THE SAME THING LUCKILY IN A PARKING LOT THIS TIME. THIS IS AN EXTREMELY DANGEROUS CONDITION WHICH LEAVES NO ERROR CODES SO FAR. I AM SEEING MANY SIMILAR COMPLAIN TS ONLINE. TAKING VEHICLE IN FOR SERVICE AGAIN ON 3/3/15 AS THE ISSUE OCCURRED AGAIN TODAY 3/2/15. *TR

HELLO, WE WISH TO FILE A COMPLAINT ON THE 3.5 L ECO BOOST ENGINE IN OUR 2011 F150. WE HAVE HAD NUMEROUS ISSUES OF SHUTTERING, LURCHING, "LAG", LOSS OF POWER/LACK OF RESPONSE. WE FIRST HAD THIS ISSUE PASSING A SEMI ON A 2 LANE HIGHWAY JULY 2014, NO THERE WAS NO FOG/RAIN. IT IMMEDIATELY SHUTTERED, SHOOK,LURCHED (COUGHED/SPUTTERED) LOOSING POWER AS WE WERE PASSING. WE MADE MANEUVERS TO GET TO THE SHOULDER WHERE IT STRUGGLED TO STAY ENGAGED. WE COULD HAVE BEEN HIT HEAD ON, REAR ENDED, SIDE-BROADED BY THE SEMI OR WORSE, A COMBINATION OF ALL 3. NOT TO MENTION STRANDED. WE HAVE READ OF OTHER ISSUES, LAWSUITS AND COMPLAINTS BEING FILED. THE "SHIELD" DID NOT WORK (WE HAVE IT, INSTALLED 8/2014 & FLASHED COMP) IT HAPPENED AGAIN TWO DAYS IN A ROW LAST WEEK. THE TRUCK HAD NO LOAD EITHER TIME, WHAT IF WE WERE/ARE PULLING OUR TRAILER?

TL* THE CONTACT OWNS A 2011 FORD F-150. THE CONTACT STATED THAT THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE TECHNICIAN DIAGNOSED THAT THE TURBO BOOST NEEDED TO BE REPLACED. NO REPAIRS WERE MADE TO THE VEHICLE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 78,626. UPDATED 4/6/15*CN

TL* THE CONTACT OWNS A 2011 FORD F-150. WHILE DRIVING AT APPROXIMATELY 45 MPH, THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO A DEALER. THE TECHNICIAN STATED THAT THE VEHICLE WAS OPERATING AS DESIGNED, BUT THE FAILURE RECURRED. THE VEHICLE WAS TAKEN BACK TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE SPARK PLUGS NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 15,500.

MY VEHICLE IS EQUIPPED WITH THE 3.5 LITER ECOBOOST 6 CYLINDER ENGINE. UPON ATTEMPTING TO PASS A VEHICLE WHILE TRAVELING AT FREEWAY SPEEDS, THE VEHICLE BEGAN TO HESITATE AND THE ENGINE FELT ROUGH. THE VEHICLE REFUSED TO ACCELERATE, CAUSING ME TO SWERVE BACK INTO THE RIGHT LANE TO AVOID BEING REAR-ENDED BY A VEHICLE TRAVELING IN THE LEFT LANE. AFTER APPROXIMATELY 30 - 60 SECONDS, THE VEHICLE WOULD ACCEPT THROTTLE AND RESUME NORMAL OPERATION. THIS PROBLEM HAS REPEATED ITSELF ON MULTIPLE OCCASIONS AND MY VEHICLE IS CURRENTLY AT THE DEALERSHIP FOR THE 7TH TIME TO REMEDY THIS PROBLEM. IN ONLY ONE INSTANCE OF THE MANY THAT I'VE HAD, I DID GET A CHECK ENGINE LIGHT ON. FORTUNATELY, THIS WAS DOCUMENTED BY THE FORD DEALERSHIP AS ONE ENTIRE BANK OF CYLINDERS MISFIRING. ADDITIONALLY, I HAVE BEEN COMPLAINING OF TRANSMISSION SHIFT ISSUES, WHERE AT SLOW (LESS THAN 10 MPH) SPEEDS, THE TRANSMISSION...

AT HIGHWAY SPEEDS THE VEHICLE WILL NOT ACCELERATE. IT WILL BACKFIRE AND SPUTTER. THIS LAST INCIDENT ON 1/22/2015 ALMOST CAUSED A SERIOUS OR FATAL ACCIDENT AT HIGHWAY SPEEDS WITH A TRACTOR TRAILER. I TRIED TO PASS, WHEN I STEPPED ON THE GAS THE ENGINE BACKFIRED, THE ENGINE LIGHT CAME ON AND STOPPED RUNNING IN THE MIDDLE A TRAFFIC. A SEMI ALMOST KILLED ME AND MY PASSENGER. I WAS ABLE TO GET TO THE SIDE OF THE ROAD, TURN THE KEY OFF AND THEN RE-START THE ENGINE. NOW THE ENGINE WILL BARELY ACCELERATE FROM THE START. I HAVE AN APPOINTMENT ON 2/4 TO TRY TO FIX THE PROBLEM. THIS HAS BEEN AN ONGOING PROBLEM SINCE I PURCHASED THE TRUCK. IT HAS NOW GOTTEN INCREASINGLY WORSE AND DANGEROUS. *TR

TL*THE CONTACT OWNS A 2011 FORD F-150. THE CONTACT STATED THAT WHILE DRIVING 10 MPH, THE VEHICLE JERK AND CRASHED INTO ANOTHER VEHICLE WITHOUT WARNING. THE FAILURE RECURRED SEVERAL TIMES. THE VEHICLE WAS TAKEN TO THE DEALER, WHERE IT WAS DIAGNOSED BUT NOT REPAIRED. THERE WERE NO INJURIES REPORTED AND NO MEDICAL ATTENTION WAS REQUIRED. A POLICE REPORT WAS FILED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 30,000.

GOING UP HILL, STEPPED ON GAS, TRANSMISSION SHIFTED DOWN ONE GEAR, LET OFF GAS AND ENGINE DIED. IT SHOWED LOW OIL PRESSURE ON DASH. STEERING WAS HARD (HAD TO PULL TO SIDE OF ROAD). VEHICLE WAS THEN TOWED. OIL DIP STICK WAS PULLED OUT AND WILL NOT GO BACK IN. LATTER DISCOVERED ENGINE IS SEIZED UP FOR NO KNOW REASON. *TR

THE ECOBOOST ENGINE FLASHED THE CHECK ENGINE LIGHT AND STARTED BLINKING AND LOST ALMOST ALL POWER, VEHICLE SLOWED TO APPROX 35 MPH IN THE MIDDLE OF HIGH SPEED TRAFFIC. FORD SAYS THE RECALL NEVER HAPPENED BECAUSE YOU CLOSED IT WITH SATISFACTORY REPAIR RESULTS. I AM TOLD I HAVE TO NOW PAY FOR THIS FIX SINCE IT IS AFTER THEIR 3 YEAR/36,000 MILE WARRANTY. YET THE VEHICLE ALMOST KILLED US. THEY SAY THEY HAVE A MISFIRE , CAC FIX TSB TO CORRECT THE ISSUE. *TR

GENERALLY SPEAKING WITH A NEW VEHICLE I "BABY" A NEW VEHICLE UNTIL I GET OVER 75,000 MI. FIRST INCIDENT - NOTICED AROUND 40,000 MI. WHEN ACCELERATING TO PASS AT HIGHWAY SPEEDS THE VEHICLE SHUDDERS AND DOESN'T HAVE POWER. THOUGHT IT WAS BAD GAS, TURBO LAG, OR INTERMITTENT TRANSMISSION ISSUE. PROBLEM OCCURRED A FEW TIMES OVER THE YEARS, EVERY TIME WAS DURING ACCELERATION TO PASS OR MERGE ON TO EXPRESSWAY CONDITIONS. KEEP IN MIND SINCE I WAS IN THE BABYING MILEAGE RANGE I RARELY PERFORMED SUCH ACCELERATION. BUT AFTER A COUPLE OF OCCURRENCES, I DISCUSSED THIS WITH A FRIEND THAT ALSO OWNS AN ECOBOOST AND HE THOUGHT THE SAME REASONS. I HAVE 7 YEAR 100,000 EXTENDED WARRANTY SO I THOUGHT I WOULD WAIT UNTIL THE PROBLEM OCCURRED FREQUENTLY ENOUGH TO EASILY TROUBLE SHOOT. OF COURSE FREQUENCY WOULDN'T BE ENOUGH UNTIL AFTER I GET OUT OF THE "BABY" STAGE ON MILEAGE. CURRENTLY...

SAME AS PREVIOUSLY REPORTED BY MANY OTHERS: MISFIRE UPON ACCELERATION UP A HILL; REPORTED TO DEALER WHO FOUND NO ERROR CODES. HAPPENED AGAIN SOON AFTER, THIS TIME ACTIVATING ENGINE WARNING LIGHT. DEALER REPLACED CYLINDER COIL; NEXT DAY, SAME TYPE OF MISFIRE OCCURRENCE. VERY UNSAFE SITUATION, COSTING ME LOTS OF TIME AND MONEY. IN ADDITION, THIS ECCOBOOST, AS I HAVE REPORTED TO FORD SINCE IT WAS NEW, HAS NEVER ACHIEVED EVEN CLOSE TO RATED MPG, ONLY AVERAGING 14 MPG OR 40% LESS THAN ADVERTISED. VEHICLE NOW BACK AT LIVERMORE FORD, WHERE TECHNICIAN WAS ASKED BY SERVICE DEPT TO DRIVE UNIT HOME HOOKED INTO COMPUTER TO SEE IF PROBLEM CAN BE DIAGNOSED. THIS IS AN UNACCEPTABLE AND UNSAFE SITUATION. NOT HAPPY. *TR
