I experienced lack of acceleration, sputtering, shaking from the vehicle while trying to pass on a 2 lane rural highway. This is second event of this nature and the first since having Ford make certain repairs to engine to correct this issue. I have the V-6 eco boost engine. I am unhappy that this engine encounters this problem and it could result in a wreck with loss of life. This should be taken seriously!

The contact owns a 2011 Ford 150. The contact stated that the brake pedal and accelerator pedal were too close together. As a result, the contact was constantly depressing both pedals at the same time and almost caused a crash. The manufacturer was not made aware of the defect. The vehicle was not repaired. The failure and current mileage was 25,439. Updated 10/02/14

I was driving down my street and braked to pull into my driveway, after in my driveway I touched the accelerator (to get up the slight grade) and my truck went wide open throttle!! I mashed on the brake but the truck continued to accelerate uncontrollably and crashed into my brick home. Even after impact and me continuing to apply full brake it was still wide open throttle and burning out. I finally came to my senses and shut the ignition off and the stopped it. I had the truck towed to my local dealer as recommended by Ford customer care rep. The dealership ran a diagnostics check and found nothing as well as tried to get it to duplicate the problem with no luck. I had a state trooper certified in downloading event recorder data do such to my truck. The data shows exactly what happened..but does not differentiate between the accelerator being pushed vs.the accelerator position as indicated. However, it does show service brake applied and continual acceleration at the same time which I can prove was not done by me! I have pictures of abrasions to my right shin and knee from the steering column and dash..my right foot was fully applied on the brake pedal causing the abrasions at impact due to being directly in line with the steering column. My left leg had zero abrasions...since to the left of the steering column. If I was to be responsible for the data shown in the down load I would of had to have my left foot on the brake and thus sustaining abrasions to that leg. It is also impossible to use the right foot to brake and accelerate simultaneously to achieve the acceleration indicated...ones leg has to be cocked to the side and out of line of the steering column. Everything on my pickup is oem....including the floor mats...which contrary to some beliefs that could be the cause. My truck has sat at the dealership untouched since they looked at it.

While driving down highway tried to accelerate to pass truck vehicle lost power and check engine light came on. Pulled off road and shut the vehicle down and then restarted vehicle. Later loss of power on any incline that I approached.

While traveling down the road and the need to accelerate to pass a much slower vehicle my truck lost all power and began shuddering very bad. With oncoming traffic approaching quickly I had to step on the brakes rather hard and quick to avoid a accident. What would have possibly happened if I was towing a legal but heavy load? Ford has a known problem with the coils on the ecoboost and this truly needs to be addressed. This is a extremely serious traffic safety when you loose all power and the severity of the shudder that also occurs.

I accelerated hard on a highway entrance ramp and the engine started to stutter to the point I thought it might stall out. I let off the gas and accelerated again more slowly with no problem. Thinking it was a one off I accelerated hard again and again the car stuttered. I went easy for a couple days and then again accelerated hard a few days later with the same result. I got online and realized I wasn't the only one having issues with this engine. On 4/18/14 I took my truck to the dealership(landers Ford, collierville, tn) and reported the problem. They were familiar with it and said there was a fix. This fix included installing a moisture deflector and reprogramming the computer. It was performed and I left the dealership. Yesterday, 4/23/14, it happened again. I am planning on going back to the dealership tomorrow.

When attempting to pass a slower moving vehicle, I moved into the left pass lane and pushed on the gas, the truck began to shudder violently, lose power, and the check engine light came on. I took it to the dealership where I bought it and they did the intercooler fix. After that the problem continued. Check engine light came on, took back to dealership, they told me it was a spark plug, replaced it, on the drive home same problem, engine shudders violently, loses power, goes into limp mode, and check engine light either flashes or goes solid. I have had this problem since the day I purchased the truck new from the dealer.

The subject pick up truck was southbound on I405 between orange ave and cherry ave in long beach California. The vehicle was in the fast lane or the lane adjacent to the fast lane. Speed at the time of the incident was approximately 65 mph and the cruise control was engaged. Traffic was moderate with all lanes moving at freeway speed. Without warning, and simultaneously with the sound of a skidding tire, the vehicle pulled violently and abruptly to the right, out of control, and crossed all traffic lanes of the freeway and the shoulder of the freeway. Just prior to departing the roadway, enough control was regained to avoid hitting a freeway directional sign in the landscape median. The truck entered the landscape median and came to rest facing South, parallel to the freeway. Approximately 10 minutes passed before the California highway patrol responded to the accident site. The officer said he was responding to an accident that was reported. The vehicle was towed to a local Ford dealer for investigation. Five to ten minutes prior to the loss of control, the driver noticed a fluctuation in the speedometer from approximately 65 mph to 50 mph with no change in vehicle speed, engine RPM or performance. Several weeks prior to the accident, the driver experienced an event at moderate speed which was described as feeling though the vehicle was hit from behind at slow speed although there was no one behind the truck. Simultaneously, the speedometer and tachometer both failed to 0 and the dashboard display went blank. Shortly thereafter, a "wrench" icon appeared momentarily on the display. The driver continued driving to a gas station and refueled. When the engine was started after refueling, all instruments appeared normal with no icons present. No icons re-appeared at any time up to and including the date of the accident. Updated 06/16/14

During rain storm or high humidity driving conditions, while at a steady speed for a few minutes, I apply the gas pedal to pass or merge, my truck stutters and loss of engine power occurs. When this happened it caused truck to slow down to unsafe speeds rapidly while on highway, causing me to steer to the side of the road to avoid a crash. The truck is still on when this happens but accelerator peddle is useless until vehicle is stopped, after a few moments it will work again. This happened multiple times and on multiple dates. One particular trip from Pennsylvania to Florida and back, this above condition happened no less than 15 times. Had my truck in for multiple services and nothing, but a code for misfire I believe the tech said. Had all tsb's done as of August 2013. My truck is averaging very bad gas mileage between 8.5 mpg to 12mpg. My truck also stutters while in reverse while backing out of my driveway on cold days.

This is a 2011 Ford F150 with ecoboost engine. 3.5 liter V6 dual turbo. I purchased the truck 12-7-13 and it failed on 12-27-13 having problems accelerating. It has no power and the turbos do not work at random. The loss of power all the time is a serious safety concern. Luckily I did not crash or cause a crash because of the issue. But the truck has been in for service since 1-30-14, has been out of commission for over 30 business days and no dealership can fix it. The truck is under multiple warranties, but the issue of the turbos failing at random / ingesting moisture from the inter cooler is still there. 3/31/14 the truck is still at a dealership.

2011 Ford F-150. Consumer writes in regards to vehicle unintended acceleration. The consumer stated the incident occurred while exiting a car wash. The vehicle accelerated on its own and would not stop, even with him standing on the brake. The vehicle stopped only after hitting a parked vehicle. The other vehicle sustained extensive damage.

I should note that my truck has the 3.5L ecoboost engine. This occurred on a very cold morning (-15F) while attempting to pass a truck on a 2 lane highway, going up hill. I had been driving approximately 1 hour when this happened. As I pulled into the left lane and accelerated hard, the truck began to shutter and misfire, losing almost all power. The check engine light flashed 3 or 4 times then came on solid. I was able to drop back into the right lane behind the truck and avoid an oncoming vehicle. I limped the truck to an area where I could get off the road. After turning the truck off and restarting the engine, it ran better but not at what would be considered full power. I got to my destination about 20 minutes later, left the truck sit for about 2 hours and headed back towards home. The engine seemed to run normally at cruising speed. Since that occurance, I have noticed a drop in gas mileage and intermittent misfires or shuttering of the engine when accelerating hard. I believe this has the potential to create a significant safety hazard upon acceleration to pass or to merge into traffic. This truck basically died and lost all power. This is clearly not an isolated issue, as I have read numerous complaints on various Ford truck forum websites.

I was driving my Ford F150 ecoboost at highway speeds for about 1 hour, a light rain started with humid conditions. While traveling around 60 mph I attempted to pass another car but my truck would not accelerate. It began to shake and shudder when I tired to increase speed which almost resulted in a collision because I was unable to accelerate while passing. My truck has now returned to normal function but I have become aware that the issue I had has happened to several others. This is very dangerous because your truck is running just fine and all of sudden it will not accelerate.

My family and I were on our way to disney world in orlando, Florida when my 2011 Ford 3.5 liter ecoboost F150 truck completely shut down on the interstate 10 highway in the middle of nowhere, probably 60 miles to the East of tallahassee Florida. At first I thought that we were not going to make it, as the truck completely died out. I pulled off to the side and finally got the vehicle started. We had been steady state cruising with the cruise set at 70 for atleast 2-2.5 hours. After doing some reading I see that it was probably condensation in the intercooler that entered the intake tract when I had accelerated to go around a big truck that was barely making it up a hill on interstate 10. This was a real bad experience, this has happened atleast 2 times since then. Luckily I have not had a wreck or crashed, but as I keep reading up, I see many people complaining about the ecoboost F150. Now, I have a truck in the shop with a blown motor, and I can only imagine that the water getting into the motor and the motor trying to compress that water was what caused my engine failure. I metal from the internal rotating assembly shoot through the side of my engine block last week. I believe that happened due to the water and the water bending the connecting rods. Please help.

We were driving in normal conditions, going about 40 mph, all of a sudden we lost power/acceleration and truck jerked, and brakes seemed to applied by their selves very hard. This seemed to happen sporadically until about a week ago. Its happening now at least 3 times a week. The truck is driven everyday on the interstate and my husband is very concerned that he is going to cause an accident. It happened yesterday and he said it was so bad, when the loss of power happened, the brakes locked so bad the tires just screeched. He took truck to the dealership on 3/4/14 and they could not find anything wrong with the truck. On the way home from the dealership (same day) it happened again. After the dealership told him that, I began searching on the internet and found the loss of power/brake problem. (moisture in cooler causing loss of power problem in F-150 echboost engines) he called the dealership back and he told them about the info on the internet that we had found, and that if had happened again that same day, they told him they were aware of the echboost problem, but can't do anything about it until a recall happens, so they did nothing to the truck.this is definitely a problem and it is going to cause a collision and possible death or injury when this happens. There definitely needs to be a recall on the F-150 ecoboost trucks. Please help everyone that owns this vehicle and issue a recall.

While accelerating the truck hesitates, looses power and jerks violently, the check engine light flashes several times while passing a vehicle. When the truck jerks and looses power it feels like the engine is about to explode. Has almost caused several accidents because of the sudden lost of power. It appears to me that the truck is misfiring.

While driving my F150, V6 ecoboost engine, down the interstate, when I try to accelerate, the truck to pass vehicles and or move out of the way of on coming traffic, the engine gives me nothing and shutters, feels like it is missing. I originally started to feel this in 2013, took it to the dealership, cause I thought it could be a transmission issue, and the service rep only asked if a light came on and if none has come on, probably won't show anything. I am outside of my warranty now and the truck is shuttering very badly when I try to accelerate anywhere, besides my gas mileage has dropped significantly, which now can become a epa issue. I have read about a lot of issues concerning this year Ford with same engine with no outcomes. I have been told, once again that if I don't have a check engine light, then it probably wont show a code. I don't know where else to turn but to at least have a complaint filed where there is an issue with the 2011 Ford F150 V-6 ecoboost engine.

The vehicle lost power after accelerating to higher speed when entering the highway. This has happened multiple times when passing or entering highway at higher speeds.

I was traveling on the interstate where I live and was trying to get up to speed to merge with traffic and when I accelerated my truck lost power and began to sputter and shake, and would not get up to speed, and the check engine light came on, when I took to the local dealer where I purchased it I was told number 2cylinder and number 4 cylinder was mis firing, that I needed new coil packs so I had them replaced and I am still having the same problem.
