Problems with 2012 Ford F-150 FUEL SYSTEM, GASOLINE

On average, the 2012 Ford F-150 starts to “feel” problems with the FUEL SYSTEM, GASOLINE and its various aspects after 21 402 miles.

Recently reported FUEL SYSTEM, GASOLINE problems on 2012 Ford F-150

Tl* the contact owns a 2012 ford f-150. while the vehicle was idling at a traffic light, it stalled and failed to restart. the contact stated that the fuel pump fuse was replaced and the vehicle restarted. the vehicle was not diagnosed or repaired. the manufacturer and dealer were not contacted. the approximate failure mileage was 73,000. .*bf the consumer stated had to purchase a rewire kit from ford to prevent the problem. *tr

I was attempting to approach traffic onto the interstate. i was approaching highway speeds at approximately 65mph and loss power to the vehicle. i had to swerve onto the median to avoid a collision with an 18 wheeler. it was raining at the time. *tr

The vehicle decelerated when i was merging onto two lanes of a interstate from a two lane on ramp. i was in the left lane of the on ramp and had a vehicle on my right and two semis in the interstate lanes. i had been on the road about 45 minutes in a light rain the whole time. i tried to accelerate to get out of the wedge and get onto the interstate and the engine began extreme sputtering and decelerating. i had to hit the brakes to avoid being sandwiched between the vehicle on my right and the two semis. i have seen ford's report stating it only lasts for seconds and the vehicle will accelerate. that is incorrect, due to the extreme sputtering, my vehicle had to decelerate and it did not clear up for a least 2 to 3 miles. i also understand that the nhtsa has dropped the case. i can only tell you that this was a very near miss for both the nhtsa and ford with 3 people in vehicle. i also see that for has told the nhtsa that they have repaired all the affected vehicles. really. i just got mind fixed today and that was after it was supposed to be fixed yesterday but the dealership didn't put the bottom shield on because they thought it wasn't supposed to be put on my vehicle. i think the nhtsa has put itself in a bad position by siding on this issue with ford. *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

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

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

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

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

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 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

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

Attempting to pass on interstate, vehicle bogged down until i took my foot off accelerator, at this time my speed had declined from 65 mph to 50 mph. during the past 2 weeks this has occurred other times. this has never occurred since i have owned this vehicle but i am concerned. once thing that i noticed that this has happened on rainy days. i was called by a friend that bought a similar vehicle make model equipment and motor and mentioned that he was aware of a problem made aware to him by a friend that works as a ford service manager. i have scheduled an appointment with my local ford dealer. they seemed indifferent as to this being a potential problem. i am submitting this complaint because if this is a common problem that is actually happening, ford needs to step up and make this known to other owners to prevent something bad happening involving lives. *tr

While driving on interstate i attempted to pass a slower vehicle. after moving over and accelerating - the truck buckled and stalled! i was almost rear ended by an 18 wheeler at 65 mph! this was very close to being a serious accident involving multiple vehicles. please investigate and resolve this issue as ford doesn't seem to be concerned about it. not to mention i took it in for ford to repair the problem and they refused to make the repairs as the vehicle did not show a trouble code. i looked online and there is a tsb on this vehicle by ford for the repair but ford won't make the repair. not to mention since then the fuel mileage has dropped drastically since the event. this has happened three times now. i am very worried about an accident with this issue, not to mention it going out of warranty and i should not have to foot the bill. this is a design flaw and there are lawsuits all over the internet for this same reason. this is our family vehicle and it losing power is a huge safety issue due to tractor trailers not being able to slow down in time when this happens on the interstate. when the vehicle lost power it drops the vehicle speed to 40 mph. not a safe speed for contested interstates. i bought this vehicle in april and spent 40,000 dollars on a truck that's very unsafe but not even dependable. this vehicle has a 3.5l ecoboost engine with an automatic transmission and it also shudders at various speeds with a hard clunking sound during gear changes. thank you. *tr

I had the tsb (for known surging issue) performed on my truck (2012 super crew 4x4) in may at 25k miles. everything seemed better, until... this past saturday, i left the house at 5am for a 7.5 hour/ 350 mile drive from home. it was raining continuously for the first two hours. sometimes hard rain, but it didn't stop for the first 2 hours. i was driving back country roads with mostly 55 mph limits and rolling hills. given the weather, type of roads, time of day, etc. i drove gently for the trip, never put my foot in it. then, when going up a steeper hill that required more throttle than the others to keep my speed up, the truck started hesitating. a lot. more than it ever had before the tsb. and then, just after the hesitation began, something extra occurred that had never happened to it before. the truck started to shudder. this shuddering was akin to driving over road shoulder rumble strips on steroids. as soon as i let off the gas, the shuddering stopped. i gently pushed the pedal, shuddering was back and just as bad. let off again. it stopped. pushed the pedal again. it came back. pushed the throttle once more, and it had stopped. i slowly pushed further on the throttle and it didn't do it any longer. by this time i was down to about 35-40 mph going up the hill. so i pushed down the pedal almost to the floor. the truck kicked down and accelerated with only slight moments of hesitation. not once did the check engine light come on. . thus, i had a textbook case of exactly what the tsb was supposed to solve, but didn't. *tr

On trip from louisville ky. to atlanta, ga in the rain, truck displayed the shuddering stall caused by condensation in the charged air cooler which gets ingested into engine causing motor to go into limp mode, truck has had two of the three tsb's performed as this is the seventh incident of the same problem since new. when truck goes into limp mode at highway speeds you are immediately at risk from rear end collision. *tr

When passing and increasing speed, vehicle lost acceleration. no accident occurred but could have caused a head on or other accident. *tr

I was merging on the on ramp to obtain highway speed i stepped on the gas when all of the sudden the truck started to shake really bad. i tried to step on the gas to accelerate but there was no throttle response to the engine as the truck continued to lose speed. every time i tried to step on the gas the truck would shake even worse. i pulled over to the side of the road so i would not cause an accident. this is not the first time i have experience this shudder in the truck. *tr

The truck started to shudder and there was a loss of acceleration and power. *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

While passing another car the throttle would not respond with full power. *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

While attempting to accelerate from a stop sign turning right my 2012 ford f150 platinum 4x4 ecoboost stalled and would not accelerate for a few seconds. i thought the truck shifted into neutral but that was not the case. this has happened several times within the last 3 months and is getting more frequent. *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

Traveling on the interstate, little to no uphill or downhill grade, speed approximately 55, attempted to pass a tractor-trailer. pressed hard on the accelerator pedal, and started the pass. halfway thru the pass, passing speed 65-70 mph, my truck lost all power and started shaking violently. i backed off the accelerator, and pulled back in behind the tractor-trailer, then off to the right shoulder. i shut the engine off, opened the hood, expecting to see something bad. no visible signs of anything wrong. started the engine, drove the rest of the way home, with no other mis-haps. however, the same thing has happened twice more, the most recent being just a few days ago, 6-10-13. each time this has happened, it has been during an attempt to pass a slower vehicle, during a hard acceleration. i'm typically a very conservative driver, and bought this truck with this engine for both fuel economy and power to pull a trailer. on the first and third occurrence, i was on the interstate, with traffic going the same direction. the second time it happened, i was on a slight upgrade on a 2-lane road, and attempted to pass a much slower vehicle. there was traffic coming from the other direction, but there was ample time and distance to make a safe pass, as the truck in front of me was very slow. again, halfway thru the passing attempt, i lost power, and had to back behind the truck in front of me. fortunately, there was sufficient room for the oncoming traffic to move over to avoid the collision. i have talked to my dealer about this, and they were going to research the issue before servicing it. however, i recently saw a report on this issue on the local news station, and realized that my problem is not unique. *tr

This write up is for a 2012 ford f-150 truck with the 3.5l ecoboost v-6 installed. jan, 2013-while driving on i-24e, i was pulling out from the rest stop, just north west of exit 1. i went to pass a 18 wheeler and my truck came "unglued". it practically died in the passing lane when i pressed the gas peddle. it shuddered so hard; i didn't think i would be able to get off of the road before it died. it was missing and shuddering like crazy. i pulled off exit 1, shut the truck down and restarted. it ran ok without that same thing happening on the way home. i had a pretty descent "miss" in 6th gear, running down the interstate at 75mph. something very strange happened here. it was the first issue i've had with my truck. although i've noticed recently the mpg is down by 2.0 mpg or more for the last three weeks, and this from refueling at different locations, and the same driving style. ford applied the tsb to reprogram the pcm/tcm to latest level, installed a deflector shield on the intercooler and possibly replace the drivers side catalytic converter if needed. july, 2013- this weekend while driving on i-65n, i had the same issue happen. the truck now has 17,000 miles on it. i've had the vehicle back into my local ford dealer four times for this issue. the vehicle exhibits this issue when it's rainy and has been driven in the rain for several (50 or more) miles. in heavy traffic this is a very dangerous issue. the vehicle goes into some type of safe mode and will barely limp off the road. if this issue were to occur while crossing a four lane hwy, and sputtered one could be seriously injured or injure someone else. *tr

Ecoboost engine has a terrible miss at idle and blows black smoke at start up. fuel mileage is also bad due to rich fuel conditions. ford has replaced many parts including injectors and plugs that were carboned up. now ford refuses to do anything else until a new calibration program is released mid august 2013. the truck has spent a total of 6 weeks in the shop and is only 10 months old. bottom line...ford refuses to honor the warranty. they cant fix it and they wont buy it back. *tr

During any hard acceleration such as merging into traffic, the truck stalls and goes into a mode of missing and engine stall. this has happened since i have owned the truck and only happens during a hard acceleration. i have had a catalytic converter replaced and the tech at the dealer told me it was know defect with the design of some kind of moisture pump. he said that ford would only fix it when you got to the fourth converter replacement. this is a hazard during merging into traffic. *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

Cpsc#i1290626a. 2012 ford f150. consumer stated there was gas fumes in the cab of the truck. *ln the consumer stated he took the vehicle to the repair shop twice.

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

On numerous occasions while accelerating to merge into traffic or to pass a slower vehicle or hard accelerating from a standing stop vehicle shakes and stalls, stays in second gear and has no throttle response, in wet or dry conditions, sometimes completely dying. on one occasion vehicle stalled and died while entering expressway causing me to have to run off road, hitting a sign and dirt bank to avoid approaching semi truck. engine oil is diluted with gas, has burning smell in engine compartment. we are afraid of engine explosion and fire, burning smell is so bad. ford has attempted several fixes, but problem continues, now there is a grinding grunt when going into reverse. *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

Almost got hit trying to pass a car. when i pulled out to pass and tried to accelerate the motor started missing badly. ford supposedly did not have a fix until early this year. my eco bust now has 70,000 miles and ford wants me to pay for part of the repair. they have never contacted me to inform me of the problem. *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. at times when you put it in gear it feels like the power train is bumping as though your getting stuck are hit from behind. *tr
