Vehicle once when first bought shut down during rain conditions when trying to excel. It was like you ran into a wall. Ford then said it was a wiring harness problem. It continued missing at times over the last two years. The same thing happened again in december while trying to pass a vehicle and it was again during rain conditions and just shut down in the road. We took it into the dealership and they said it was tsb 13 8 1 and made repairs. Vehicle now does not run right and gas mileage has dropped by at lest 2.5 mpg. Noticeable power loss. Vehicle is the ford 3.5 echo boost. This is a big problem for consumers who want a truck and expect power with good mpg but should not be afraid to drive or get a supposed fix that's not what you have purchased. These situations will result into some very bad accidents. I cant imagine pulling something and this happens. Bottom line consumers deserve safe reliable vehicles. We love fords and I hate I am having to complain but this is a real big problem. Please investigate. Thanks!!!!
2011 Ford F-150 fuel system complaints
Page 4 of 5: complaints 71 to 100 of 117, newest first, as owners wrote them.
Under hard acceleration on the highway, the engine began to cut out and misfire, then the check engine light began to flash. I took the vehicle to the dealership and they said the innercooler had failed and needed to be replaced. Now, at roughly 55,000 miles it has begun to do it again, I had noticed it some before, but now it is worse. I took my 2011 f150 with the ecoboost to the dealership again and they said a tsb had been written and they changed the replaced the lower air deflector. This actually made the problem worse. At wide open throttle from a stop to about 80 MPH, every gear will cut out and sometimes put the engine into a protection mode beginning around 4,000 RPM. If it shakes and shudders made enough the check engine light will flash, and now it has come on and stayed on. It has been very dangerous if I pull out to make a pass and then the engine shuts down and I can no longer accelerate. This has happened dozens of times, and has been addressed twice now by the dealership without any fix.
Returning home from a weekend camping trip with my family and pulling a travel trailer via I-81 in va, I depressed the accelerator approaching a long hill, and abruptly lost all engine and drive power, the engine shuddered violently, the transmission downshifted to lower gear and the check engine light flashed a few times. We had absolutely no power and I thought the engine was going to shut off. I was in the 2nd lane from the right and had to quickly move to the right lane then to the shoulder to avoid being hit from behind. This was very dangerous while pulling a 34' travel trailer. I had to pull the vehicle to the shoulder and stop completely to regain control. I had to put the truck in park and turn it off before it returned to somewhat normal drivability. While continuing to climb the uphill grade, the engine misfired and hesitated constantly. I could only apply gently pressure to the accelerator to keep the vehicle moving. Once over the hill the vehicle picked up speed and returned to normal drivability for the remainder of the trip. The same exact problem occurred again a few months later while driving south on rt-4 in md with my wife, and not pulling a trailer. This time I didn't shut the engine off, but had to pull to the shoulder to regain control and engine power. As I continued on rt4 the engine misfired and hesitated several more miles. Once at my destination I turned the vehicle off, then upon departure the vehicle operated more normal, but experienced misfire and hesitations several mile returning home. The next day the vehicle operated normally, but I took it to the ford dealership to have it repaired. This is a very unsafe situation and makes me very leary driving this vehicle on a normal basis. If I was accelerating while crossing the highway and this problem happened, there is a great chance of getting into an accident or causing one.
We were merging onto the highway outside of st. Louis mo and when the accelerator was fully depressed the engine started to misfire and power was reduced. A blinking cel was displaying on the dashboard. It seemed as though the turbo system was not adding any extra charge to the ambient air. There was a pronounced vibration to the vehicle that seemed to originate from the engine/drive train. Luckily there as not a lot of traffic at the time and our poor acceleration did not result in an accident. My solution was to manually select the gears and drive at much higher RPM. This smoothed the misfire and we had an adequate amount of power to keep up with traffic. After about 10 minutes everything smoothed out and the misfire was gone. Truck behavior returned to normal. The weather that day was a pleasant 60 degrees and sunny. The previous day we drove from central ohio to st. Louis through much rain and fog. Since we were on vacation and away from home we did not take the truck to a dealer to be serviced. The problem has not occurred since then. There was one previous occurrence at a previous date. I don't know exactly when it was. We were traveling home to vt from ohio. We had been driving for many hours, mostly on highway/cruise control driving. We had just gotten off the interstate highway and were on state highway. I went to pass a slower vehicle in my lane and upon depressing the accelerator the engine seemed to misfire (RPM went up but power delivery fell flat). I stepped off the gas pedal and slowly pressed a second time and this time the truck responded as expected. There was no cel this time. Each of these incidents occurred with my entire family in the vehicle. We were not very happy about it and did not feel safe at the time.
2011 ford f150 equipped with 3.5l turbo charged engine traveling at 65 MPH began misfiring and suddenly experienced a near total loss of power, causing the vehicle to slow to 25 MPH quickly. The vehicle was traveling on a two lane highway with no shoulder and no place to pull off the road. This incident did not pose an immediate threat to car or driver, but under other conditions such as overtaking (passing) slower traffic, the sudden and near total loss of power could be disastrous. After quick research and consultation with the ford service center where I purchased the truck, I have learned the vehicle entered into "limp" mode to protect itself from mechanical damage. I have also found that this problem has long been acknowledged by ford motor company and has been the subject of a few technical service bulletins. Also to the best of my knowledge, ford, through this series of technical service bulletin's has failed to provide a permanent solution to this problem. I am filing this complaint in hopes that the federal safety agency in cooperation with ford motor company can provide a quick and permanent solution to this problem before someone is seriously injured or worse due to an engineering flaw on a motor vehicle.
Upon trying to pass a truck, when I stepped on the gas for added power, the engine convulsed and shook the entire truck, lost power, engine light flickered... I pulled over immediately, called the ford dealership, they did a check through on star (type system). Said they saw nothing?! Started back up, seemed to be fine once again. This has happened now multiple times. Always when stepping on the gas for added power, same scenario. This is the eco boost engine. While I love the power, it has failed me 5 times to date. Same problem as the pe 13-018 report.
While merging into traffic the engine began to loose power and misfire. The vehicle entered "limp home" mode, noted by a flashing check engine light. The vehicle was taken to the ford dealership and simply had the error codes cleared. Similar incident occurred few months later and the vehicle underwent recommended repair/upgrade per ford tsb including intercooler cover and reflash of computer. For past week vehicle has had persistent power loss and "shuttering" during acceleration. This not only limits the drivability of the vehicle, it also endangers the occupants when attempting to merge with traffic and crossing intersections. The dealership is aware of the problem, however there seems to be no effort to find a "complete and lasting" solution.
I have been having problems with engine noise ranging from a deep howling to a sound like a steel chain being drug over an aluminum ladder. I have had problems with the sync, memory seats and steering wheel, auto start, and an ongoing problem with hesitation or miss firing in the engine that cause the truck to loose power on acceleration and go into limp mode. I have had some really close calls getting onto the highway where I was almost hit from behind when the truck lost power. I have had the truck in the shop 13 times and getting ready to go back for the 14th time. I have tried the bbb and the lemon law program which I was denied by a third party arbitrator. I was expecting that because a bbb employee said 93% of all people that file a lemon law claim in missouri get denied. I have an extended warranty with 50,000 miles left on it and the ford engineer in charge of repairs says he refuses to do anything about the engine noise anymore because of the past failed repairs. This is an v6 ecoboost . I don't know what to do next.
Following two heavily laden 18 wheelers during a light rain storm for two or more miles on a paved, two lane county road, it came clear for me to pass, I accelerated and all went well for just long enough for me to get even with the first one in front of me. My momentum carried me far enough to pull back in front of the first truck. By that time I was in serious trouble. My truck would barely run, it was vibrating violently and there was no acceleration to get me out of the way of the truck I had just passed. Had he not braked hard for me there could have been a serious wreck. I've have had 5 other incidents with this vehicle. I've taken it up with fomoco, over a period the first year. Working through the oklahoma bbb I was assured ford would correct the problem. Fomoco sent a texas rep to my work location to put the most recent fix on the vehicle. Following this fix, we continued into a dry spell, but as fate would would have it, I was in a heavy rain within the next 2 weeks and the problem reappeared. This time my wife was in the vehicle with me. She thought I had run over something because the action of the pickup was so violent. I've occasionally seen letters to the editor of motor trend's "truck trend". Other people describing the exact thing I've experienced driving this same type vehicle (early model ecoboost v-6, those built prior to april 2011, I believe). I have a huge file from the time when I was trying very hard to get this corrected, dealerships, dates, times, correspondence, ford tech bulletins, but I refuse to waste my time with you unless you contact me acting as if something might seriously be done. ([xxx], or e-mail, [xxx]). I have enough to prove my vehicle has serious problems and fomoco admitted it. A transcript of my meeting with them through the oklahoma bbb. It's interesting what they had to say. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
Ecoboost engine stutters when accelerating. Can not pass or continue driving.
Engine misses at times of hard acceleration. Engine ecoboost.
Had a car pull into my lane, tried to accelerate to move over with out causing a dangerousness situation of a car coming up in the lane I needed to be in to avoid the idiot moving into my lane but car lost power. Thankfully the car in the next lane over saw the issues with the car moving over into me and gave me room, I'm sure they didn't expect my car to slowdown due to the loss of power. This car has the ecoboost engine 3.7 liter
Loss of significant power under slight to moderate acceleration, engine shutters violently, shakes and miss-fires. Check engine light flashes. Engine seems to run on 50% power loss, letting off accelerator for awhile then engine seems to recover temporarily until additional power is needed. Unable to have any confidence to pass any vehicles on grades. Quite possible for complete power loss under full acceleration as the engine misses so bad that it actually slows down and looses RPM's. I have owned this truck since new. Symptoms started in dry climate, no rain and have continued to get worse as I have entered into rainy areas with humidity.
Went on a 350 mile trip, I was at a stop light and when I went to accelerate the truck lost all power. I have one of the ecoboost engines. The engine did fix itself and I continued with no other problem, this is the first time I experienced this problem. 2011 ford f150 king ranch.
This is on the ecoboost f150. I was driving during a rain and had been around 70 miles. The weather was rainy. I went to pass a farm tractor on a 2 lane road and the vehicle stuttered and had no power to pass. I had to take evasive action and get back into my lane where there vehicle continued to sputter for approximately another 2 minutes. I took truck to ford and they replaced a converter and cooler. Last wednesday under similar conditions, the same thing happened again on a vacation trip. Oncoming traffic had to evade me as I tried to get back into my lane. It has been less than 10, 000 miles since last attempted repair was performed by dealer. Obviously the repair did not work and now I am left with a vehicle with an obvious design defect that ford doesn't know how to correct. Under different circumstances, this could be a serious safety issue.
2011 ford f150 ecoboost - purchased july 2011. When accelerating to pass traffic or merge into traffic. The vehicle shudders and shakes violently losing all power, the check engine light flashes the goes to solid. This was taken back to ford dealership mechanics in florida and kansas 3 times now with no fix action in place. During a road trip in july 2013, (after a trip to ford) we couldn't use the cruise control due to traveling over hills would cause the vehicle to lose power constantly to the point where some hills were almost impossible to drive over, vehicles behind me were honking and complaining as it barely made it up hills.
Six months after I bought my truck I noticed a shuttering and hesitation while I was on the highway. The shuttering happens when I am cruising at 55-60 MPH. More noticeably when the truck is climbing a slight incline on the road while lightly accelerating to maintain 60 MPH. I had the dealer look at it 3 times in the last 2 years. The first time they reprogrammed the transmission and the computer. It did not solve the problem. Brought it back the second time and I went for a ride with the technician and he noticed the shuttering. He said there was no engine light and no codes to find out what the problem is. Finally the third time they said ford is aware of the problem and there engineers are trying to find a solution. I also had problems with my transmission. I was slowing down to come to a stop and the transmission downshifted so hard I thought I got rear ended by the vehicle behind me.
Traveling on 4 lane highway during period of train, accelerated to pass vehicles, my truck eco-boost motor acceleration stagnated and vehicle began to shutter, was unable to pass, decelerated and stagnation stopped. Incident occurred when ever I tried to accelerated during active rain during a 9 hour interstate trip.
While merging into traffic on the expressway today in miami, at about 35 MPH, I had to accelerate to get out of the merging lane, at which time (for the third time since I bought the truck in 2011) the truck lost all power to the engine (a 3.5l ecoboost) and began to sputter, shake, and decelerate. Luckily for myself and the other drivers on the road I did leave a sufficient gap between myself and the car to my rear to give that vehicle time to react to what equates to a vehicle pulling out in front of him/her and gently pressing the brakes without the brake lights engaging. My truck hovered between 25 and 30 MPH for about 30 seconds with it doing the sputtering and slowing thing each time I attempted to accelerate during that time period. After pretty much coasting for 30 or so seconds, the truck sprang back to life and drove as advertised. From what I've read, this is not an isolated incident and I (as well as others) believe ford should be held accountable for this defect. I'm not looking for a new truck, I'd just like the problem fixed. Even though no deaths or injuries have been reported due to this "yet", you can see the danger of having your engine loose power when you need it the most. Unfortunately for their customers, all ford seems to be concerned with is the loss of a buck......not the loss of a life!!!

Poor gas mileage. Window sticker says 23 mpg highway, best I ever got is 16 mpg,with cruise set at 65 MPH on flat level highway. Had at dealer, 4 times, they updated computer, changed turbo intercooler and they still cant improve my fuel economy. Around town I get 12 mpg. Bad turbo lag when pulling out low power, dealer said its how turbos work. Doors rattle, speakers crackle, rear end springs make a creaking sound. 4 wheel drive makes a loud growling, sounds like gears are not meshed right. I would not recommend a new f-150 to any one. Nothing but trips to the dealer and let downs.
When I'm accelerating the engine stalls, I may be leaving a stop sign climbing over an overpass or passing another slower vehicle. Seems to happen more often about 40mph to 70mph.
Spring of 2012 acceleration failed when overtaking a slower vehicle. My speed was about 60 MPH. This happened on more than one occasion. 06/10/13. Vehicle engine began missing and vibrating when accelerating at any speed. I was driving about 45 MPH. Have sent the pickup to the dealer for inspection/repair.
My ford f150 eco boost lost power suddenly while trying to enter a rural route at a stop sign.while trying to accelerate it just died for several seconds and then took off since I was pushing on the accelerator wondering what had just happened .the vehicle has been shuddering a lot on acceleration now with a substantial loss of fuel economy . I have personally had it at two ford dealership which say they can find no problem with it , but shop foreman told me and my wife we where stuck with it and to fix it by pulling the battery cable off every once in awhile.
Rapid acceleration while passing caused engine to cut out and shudder. The second time it happened in april 2013 I had to pull over and kill the engine so the computer could reset. Took vehicle to ford dealer for warranty repair, 2 months later the problem has re-occurred.
Vehicle began shuddering heavy between 40mph and 50mph. Requiring me to depress the gas pedal heavy to avoid the shuddering, its almost impossible to drive my vehicle at 45 MPH (which is the speed limit in most of the area I drive in). This occurrence is when 5th gear changing to 6th gear, which is typical between 45 MPH. Not sure what damage this is doing to my vehicle, let alone the safety risk this may be causing. I have had the vehicle in the dealership at lease 6 times for this issue and with no results of the issue being resolved. Just the run around and false promises. 2011 f150 5.0 motor and 3.55 gear ratio.
Vehicle shut off going up hill weather cold and damp took truck to dealer on 5/20/13 found nothing wrong . On 5/25/13 vehicle shut off 11 times while accelerating. Drove vehicle on mon may 27 shut off 9 times and we were nearly run over by semi on interstate. Engine light came on on tuesday may 28 drove to dealer with vehicle shutting off over 10 times. Vehicle is a liability as well as a safety hazard for driver as well as other drivers.
I have had the stall and/or shudder problem several times. By far the worst is the date and items listed in the incident information. While attempting to pass another vehicle on a two lane highway, after driving in a steady downpour for at least an hour, my ecoboost f150 fell flat on its face. No acceleration at all. It just stalled and the check engine light came on. I let off the accelerator and tried again with no reaction from the motor. I then feathered the throttle and was able to get around the other vehicle. The truck would run as long as I didn't try to accelerate quickly. Luckily there were no oncoming vehicles in the other lane. With dryer weather the problem disappeared. Since that time I have had it shudder a few times when trying to accelerate. Mostly in damp or humid conditions.
Driving on new years day, I was traveling and needed to accelerate onto an expressway. As I pressed on the throttle pedal my ford f150 2011 seemed to lose power for a second or two before regaining power again. This was the first time I can recall, but it happens each time I press the throttle all the way down for acceleration. I have learned that my f150 is not reliable enough to attempt to pull out unless traffic is completely cleared, or I have several car lengths of distance.
Tl* the contact owned a 2011 ford f-150. The contact stated that while driving approximately 35 MPH, the vehicle hesitated to accelerate. The failure recurred intermittently at different speeds. The vehicle was towed to the dealer for diagnosis three different times. The technician was unable to diagnose the failure. Additionally, the contact stated that the fuel gauge would not display accurate fuel readings. The vehicle was taken to the dealer for diagnosis. The fuel sensor was replaced. The vehicle was not repaired. The VIN was not available. The approximate failure mileage was 4,000.
Ford ecoboost. Vehicle has few issues. First there is unexpected hesitation when pulling out in traffic. You are without power and subject to being run over. There are times when at highway speeds the engine goes limp when accelerating leaving you in traffic subject to being run over. Ford has replaced the cac and this has not happened since. When at speed and you accelerate a small amount, the engine will misfire and run rough. The lack of throttle response leaves you vulnerable when passing. Been at the dealer 5 times for these problems.
