Ecoboost, almost 5 serious accidents in a year. In jan, my wife, 3 children & I were on I-85 in heavy traffic when my truck stalled. We went from 65 MPH to 20 & no power. An 18 wheeler was barreling down on us & had to make an aggressive move with his brakes locked to miss us & the other cars. I pulled the car through 4 lanes of 65 MPH traffic, doing 15-20 MPH & turned the truck off to get it running again. Next, I was stopped at a light. When the light turned green my truck stalled out 3 times before the truck would finally go. Over the next month my truck stalled at least 10 more times. In april, ford told me that the ecoboost had a problem & they performed tsb 13-8-1, reprogramed PCM & installed deflector. I haven't notice any power loss, but lost 2 mpg from my normal driving habits. In june, I merged into heavy traffic & my truck stalled. 65 MPH to idle on a major highway. I don't know how I avoided an accident. I pulled off the highway & turned the truck off to get it going. My truck stalled 5 more times before taking it back to ford. In august, my truck stalled at an intersection 4 times. I completely blocked traffic for about 10 mins. I got on the hwy & went 8 miles. My truck stalled 14 times' very dangerous. Every time I got the truck up to speed, it would stall & I would have to pull it over & turn the truck off and restart it. In aug I took my truck to ford & they replaced the throttle body. 2 months later it was stalling again. Ford told me that it was misfiring & that they needed to change the plug boots, spark plugs & the fuel filter. I was told that it was the next step they were required to do. So now I'm paying ford to test different things & hope that something works. Yesterday I pulled out onto a busy street & my truck stalled. I was almost t-boned. I am driving a time bomb. Every time I drive this truck I am risking my life & everyone around me.
2012 Ford F-150 fuel system complaints
Page 3 of 5: complaints 41 to 70 of 119, newest first, as owners wrote them.
Vehicle is a 2012 ford f150 3.5l v6 ecoboost. Vehicle had a full tank of gas (30 gal tank). Vehicle gas gauge began to drop quickly. Compared to trip counter gallons used, vehicle showed empty tag after only using 9.2 gallons. Upon filling gas and pump entering fill hole, pressure from the tank was released more so than any other time. Gas gauge repeated same issue upon adding the 9.2 gallons to fill the tank again. Gauge once again showed empty when approx 10 gallons were used.
July 6 lost power to truck engine at 60 MPH when going to pass in hard acceleration situation. Truck engine shuttered for over 3 mins until I could get it stabilized around 2000 rpms in a lower gear/speed. This was the first of two similar situation on the same day with the truck and throughout the remainder of the day any acceleration over 3500 rpms caused a loss of power. We limped the vehicle home that day. Next day check engine light came on and off until we could get truck into our local ford dealer for service on 7-13. This issue has been researched via info on this site to no conclusion. I can say if you drove this vehicle and simulated this issue you would see the major issue this causes and potential risk of accident at highway speeds with acceleration. Specifically heavy traffic situations. The issue caused spark plug damage, catalytic converter damage and the dealer performed the tsb (4th issued by ford) to attempt to fix the issue. This is a known issue, causes safety issues and should be recalled to permanently fix not try to patch with four different tsb. Fix this correctly before accidents occur that cause deaths.

24,991mi: misfire when accelerating while driving. No check engine light. Dealer reported no problem found, no codes & made no repairs. 29,440mi: misfire when accelerating & going up & down hills specifically when in 4,5, 6 gear during both flat & inclined highway driving. This was while pulling an 8000lb trailer. No check engine light. Dealer found misfire in #1 & 4 and replaced coils & plugs in #1 & #4 only. Test drive still showed misfire, then replaced turbo boost pressure sensor. I was told that moisture had damaged the plugs & sensor. 35,214mi: misfire when taking off from a stop, during normal acceleration and going up hills.no check engine light. Dealer replaced the drivers side exhaust manifold because it was warped. 37,164mi: misfire when taking off from a stop, during normal acceleration & going up hills. I saw this in acceleration conditions from 10-60mph without towing a trailer. No check engine light. Dealer reported no problem found, no codes & made no repairs. 38,577mi: repeated severe misfires while going up moderate inclines. Check engine light came on (first time this ever happened) & I had a reduction in power, could not get out of 3rd gear & my speed dropped from 65mph to 50mph. After repair had moderate misfires during major inclines while towing a trailer but no check engine light. 39,000mi: while towing a trailer, experienced series of moderate to severe misfires in waves be ok for an hour & then go into a series of misfires for 3-10 minutes. Some were on hills, some were on flat highway driving. I had 5 occurrences where the check engine light came on during this drive. 3 of these were during a hill climb where I had a power reduction & lost speed. Vehicle stayed in 3rd gear. When I would get a series of severe misfires, misfires were so severe (without the check engine light on), that I could hear & feel the turbo kick off & on..
The truck is equipped with a cap less filler system for the fuel filler. The mechanism that controls this has failed leaving the fuel filler door to not close properly and it flaps in the breeze as you are driving. This leaves the gas line to the tank exposed and is certainly a safety issue. Normally ford has a 36mo/ 36000 warranty and on this truck there is an extended warranty of 100000 miles but when contacted about the issue they said this isn't covered and there would be a charge for repairing it. This is a safety issue as far as I'm concerned and they should be addressing it as this has become standard on all of their vehicles.
2012 f150 ecoboost engine.loss of power and truck shuddering when accelerating at highway speed from possible misfiring. Service engine light came on also, but turned off soon after event. Took to dealer to check, dealer said to change spark plugs and boots. Dealer did not mention previous or current technical service bulletins for this.
I was pulled to the side of the highway (I-95) waiting out a heavy rainstorm. Upon pulling back onto the highway, my truck would not accelerate, lost power, shook and almost stalled out..I was almost rear ended by a truck. This was the second time this happened since I bought the truck new. The first time was jan -14 under the same location and circumstances.
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.
After driving in raining conditions for more than four hours, I attempted to pass another vehicle. When I accelerated, my vehicle began to lose power and shake violently. Because of this, I nearly cause a multiple car accident do to my inability to control my trucks rapidly reducing speed. The same issue or type of issue occurred in late august of 2013 while attempting to merge into traffic. Upon acceleration attempt, the engine reduced power, failed to respond and the vehicle shook violently. A ford dealership completed tsb-13-8-1, however, it was reluctantly done as no code would verify a problem. The truck is currently at another dealership, who once I explained the problem I was having, told me that I needed to have tsb-13-8-1 performed. I mentioned it had been performed and was told that unless a code could verify a problem, nothing could be done. This is a well documented problem, with many occurrences. This vehicle is going to get someone killed if someone doesn't correct the issue. It is not something that can be "created" by a mechanic to, it only happens in real-life situations. Is there something someone can do to make ford research, identify and correct this issue before even one death?
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 federal safety agency has dropped the case. I can only tell you that this was a very near miss for both the federal safety agency and ford with 3 people in vehicle. I also see that for has told the federal safety agency 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 federal safety agency has put itself in a bad position by siding on this issue with ford.
When trying to pass a slow moving vehicle ( going 45 in a 55) I tried to pass. When I moved into other lane and gassed truck I lost power and started jerking. I had to let up completely off the gas and fall back behind the car that I was passing. This was a very dangerous situation since there were other cars behind me that had also started to pass as well as oncoming cars up ahead (a safe distance before attempting to pass of course). This seems to be a major issue since many of the same stories came up when searching the internet about this.
Under non-tow situations truck will shudder/misfire during hard acceleration. Acceleration does not have to be wot. Weather conditions can be hot and sunny or cloudy, raining and humid. Truck did not start doing this until 60,000 + miles.
For the fourth time, my 2012 ford f150 ecoboosted engine stalled or shuttered when hauling a load (trailer or heavy bed load) in a high humidity environment. I was pulling a u-haul trailer behind my truck and it was raining heavily. When I punched the accelerator to pass a slower vehicle, the engine stalled, sputtered, and nearly shut down. The "check engine" light came on for about a minute, then turned off once the engine had cleared what felt like condensation, and returned to normal operating mode. When I took the vehicle to the dealership to complain (for the 4th time), they told me that they were of aware of a design problem with the intercooler on 2011-2013 turbocharged vehicles, but since they could not verify the defect "code," ford would not reimburse them for the service fix. This is clearly a safety and environmental issue as the service bulletin that ford issued to correct the problem, requires replacement of the catalytic converter as well. Frustrated!
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
While trying to pass another vehicle during wet weather , my vehicle would loose engine power at a critical moment during passing. Ford dealer could find no problem. Loss of power happened more than one time while passing. After about one year of service I traded vehicle off....not liking the passing performance during wet weather. Then found out that this is a problem with many f150 ecoboost engines. I believe this is a serious issue.[xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
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.
Was traveling up the roadway on 6/1/14 in our 2010 f-150 xlt and went to make a turn into an intersection. The vehicle stalled and was rendered useless in the middle of the intersection. The vehicle lost complete power, steering capability, and braking was diminished tremendously. We were stalled in an intersection with cross traffic approaching at 55mph. With little time due to oncoming vehicles, was able to immediately restart the engine and proceed, before oncoming vehicles approached us in the intersection. Not very safe being that my entire family was in the truck. Ford has issued a service bulletin about the issue with the vapor canister purge valve and its needing to be replaced. However, I believe this is a serious safety issue being that the vehicle stalls when reducing speed (such as turning into intersections with other oncoming traffic coming at you). There is no recall in lieu of this potentially dangerous situation they are causing. Additionally, this problem with the canister causes a tremendous vacuum on the fuel tank, so much that it damages internal components and has raised questions about whether it is affecting the stability of the actual tank itself. When you go to fuel the vehicle, there is so much of a vacuum that you hear it release the pressure when inserting the nozzle. Immediately after fueling, the vehicle will not start for several minutes. This issue needs to be corrected before someone is seriously injured or killed due to their vehicle sitting in the middle of a roadway and being hit by oncoming traffic.
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.
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.
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.
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.
When passing and increasing speed, vehicle lost acceleration. No accident occurred but could have caused a head on or other accident.
I was travelling on a 4-lane, 65mph highway when I floored the gas pedal. The truck failed to accelerate as it should have. Instead, it acted as if it was coasting. There was no power for several seconds even when I moved the gas pedal to different positions. When the truck finally seemed to resume power, it started to shake violently. The shocked passenger and I looked at each other, then I checked to see if there were parts strewn on the road behind me. Suddenly, it smoothed out and there were no more issues on that trip. I had been driving that truck for about 10 hours with various forms of precipitation at the time. This was december 21, 2013. The second incident was on december 28, 2013. Weather conditions were sunny and dry. I had been driving about 50 minutes. I floored the gas pedal again to overtake a vehicle and was barely able to overtake due to no power. Again, I worked the throttle to no avail. The truck finally recovered but started shaking violently again. As before, it smoothed out. I took my truck to a local ford dealership where they told me it was showing no codes and that their techs could not reproduce the symptoms I had mentioned. I checked on the federal safety agency website and found this issue is under investigation. I do not agree with the service bulletins. My theory is that there is a computer programming problem specific to this direct-injection, turbo gasoline engine. I plan on trading for something other than an ecoboost engine, as this problem is dangerous.
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.
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).
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.
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.
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.
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.
I had read about this issue but thought I was one of the lucky ones that didn't have a issue. However at about 11,500 miles driving in a rainy humid day on the highway I got in a spot where I had a rig going about 30mph and I was doing about 60mph having more than enough time to pass safely before the other rig coming up in the passing lane I decided to go around.. As soon as I pushed the pedal to the floor and got in the passing lane the truck lost power,,, shuddered badly and I almost couldn't get around the rig that was only doing 30! After getting by I decided to try to get off the road and again I was successful but not without the anxiety on thinking the rig coming up would not be able to slow down enough to allow me to get off the road without pushing me off. So far there have been no known accidents but again if the conditions are right for an accident to happen could be as simple as passing on a foggy night and the person coming up on you at 70 never saw the f150 ecoboost sitting in the passing lane doing 45 trying to get it off the side of the road passing at the top of a hill with nowhere to pull off to the right as going down the hill with a 70 MPH tractor trailer driver doing his best to shut down his rig trying to avoid a jack knife due to a f150 ecoboost doing 40 MPH with no where to pull off! So any of you that think this isn't a big problem waiting to happen then I suggest one thing.... Hope,,, pray,,,, that you never come up on a ecoboost passing a rig and find yourself between a f150 losing 30 MPH and trying to get off the road, then you,, followed by a rig doing 70 MPH on your bumper in the passing lane!!!
