I was driving at 48-50- mph when I decided to pass a cement truck that was going below the speed limit. As I pulled out to pass the truck everything seemed fine. When I got alongside the cement truck my truck started to hesitate and misfire. The engine light started flashing. I was stuck from going back as another car was behind me, also trying to pass the slow truck. I barely made it past the cement truck as an oncoming vehicle had to swerve into the shoulder to miss me and the vehicle behind me. When I returned home I looked up ecoboost problems on the internet and found numerous other people with the same problem. Thankfully no one was injured or killed today, I believe the it will only be a matter of time before there is a fatality if there hasn't been one already.

I was driving from milwaukee to des moines on Sunday Sept 15th, 2013, and when I went to pass another driver in dubuque that pulled in front of me the truck lost power and failed to accelerate as I anticipated. It was raining off and on throughout the trip, temp was 55deg, and I had been on cruise control for the majority of the time before this happened. Basically, I went to change lanes and pushed the accelerator pedal and instead of gaining speed quickly I received no acceleration causing the cars behind me to have to brake quickly. During this time the check engine light was flashing indicating a mis-fire was occurring at which point I knew what was happening and got off the highway and the mis-fires ceased and after a brief stop I was able to continue my drive. My truck was built on 1/15/2013 and has all the updates to the intercooler Ford claims addressed the issue. The issue is definitely not fixed and despite Ford claim in their response to the NHTSA investigation this is a safety issue. Ford also claims in their response to the NHTSA investigation that many complaints are just against the dealers and not for safety concerns so let me be perfectly clear here this is a safety complaint!

The contact owns a 2013 Ford F-150. The contact stated that while driving 60 mph, the vehicle began to shake, wobble and lose power. The vehicle was turned off, shifted into neutral, and restarted however, the vehicle continued to run erratically. The vehicle was taken to a dealer for diagnosis and the contact was informed that a shroud would need to be placed over the inner cooler to prevent condensation. The vehicle was repaired however, the failure recurred the same day. The manufacturer was made aware of the failure. The vehicle was not further repaired. The VIN was unavailable. The failure and current mileage was 14,200.

While driving from wilson, N.C. to swan quarter N.C. in the early morning hours on a fishing trip, I started to pass a slow school bus then my truck start jumping, loosing power and the check engine light started flashing. It almost caused me to have to ditch my truck to keep from hitting another vehicle. It was a very foggy morning and I had been driving at 50 and 55 mph for a long distance before this happened.

- Lucama, NC, USA

I was driving 65 mph on the right hand side of a two lane highway. In order to pass a car that was going at a reduced speed I moved into the left hand lane and began to accelerate. Immediately, as I accelerated the engine misfired and then I lost engine power. I had to brake and get back into the right hand lane so I would not cause an issue with oncoming traffic behind me. The check engine light immediately started flashing and I pulled over. It was a dangerous situation to lose power at high speeds and the outcome could have been much worse. I was glad I did not have too much traffic behind me and the cars were able to navigate around me as I decelerated due to the engine misfiring. Scary situation to be in and disheartening after buying this truck brand new and only having 10,000 miles on it. Ford needs to do something.

While driving on a highway at 75 mph I accelerated to pass a car and the check engine light began flashing and the truck started shuddering and would not accelerate, it started decelerating. I pulled off the road and put the truck in park. I revved the engine until the turbos started spooling normally again.

- Wilmington , NC, USA

Attempted to enter interstate traffic from an on ramp. Attempted to accelerate to speed and merge into traffic. The engine lost all power and failed to accelerate, the vehicle shook violently and slowed. A malfunction indication light began flashing on the dash. A vehicle behind me had to pass me on the shoulder to avoid a rear end collision. The condition cleared itself after approximately 20 to 30 seconds. I was approximately a hundred miles into a 150 mile trip in rainy weather. Returned to the dealer the following day who retrieved numerous misfire codes from the ECM (dtc P 0903, P 0904, P 0905). Dealer re-programmed the ECM and informed me I would have to drive it and see if that works. Performed research to see if this was a common issue with the ecoboost engine and found that indeed it was, that the condition has existed since at least 2011 model year and to date there appears to be no clear fix from Ford. Additionally, despite well over a hundred complaints about this dangerous condition, that no action has been taken by the nhtsb. It is my most sincere hope that it does not take a fatality to spur action on this condition.

After driving about 200 miles at 65mph in the rain, I accelerated quickly to pass a vehicle and my 2013 Ford F-150 ecoboost truck seemed to lose power/stall and I could no longer accelerate. The engine light flashed for several minutes while this was happening and after several minutes (probably 2-3), power was restored and the engine light went off.

2013- Ford F150 ecoboost: I was driving along at highway 100km/hour highways speed. I came upon a car going 70km/hr. It was safe to pass, and as I stepped on the gas to accelerate, my truck lost complete power and decelerated to about 40 km/hr, eventually slowing right down. I tried frantically to push the gas, as there were two semi trucks behind me trying to pass at the same time as me. The trucks both ended up having to pass me unsafely on the shoulder to the left of me, into oncoming traffic. I was able to glide over back to the lane I was in, and eventually rode the shoulder. I continually tried to get power to the vehicle. My engine light was flashing. Eventually after several attempts, my truck did "grab" and shoot forward. The engine light then went off, and for the remainder of my drive, the truck was fine. Again, two days later, the truck did the same thing, but at slower speeds in town. As I read into the issue, I found that this is a "common" problem"??" my situation too was during rainy/wet weather, long distance highways the first time, and wet weather, in town, the second time. This is a severely dangerous issue. I too brought my truck to the shop and was told that this issue was being investigated and that Ford had solution to try. What boggles my mind is that there are "solution" to try, which means this problem was known, yet when I bought the truck the dealership did not make one single mention, even when I asked if they had heard of any issues with the ecoboost system! the shop just updated the computer, an a day later, it happen again! :) I'm no longer driving my truck on the highway. Not sure who to contact to return my truck. I don't even want it anymore!

This is a serious problem and a major safety issue!!! I experienced this twice last weekend on a major highway. I was driving (25mph) and all of a sudden the truck began shuddering and went into limp mode. I couldn't go more than 5 mph and almost caused and accident. The dealer was closed, so I disconnected the battery and after reconnecting it the truck ran fine, until later that night when the same thing happened but at 70mph. Once again the only thing to do was disconnect the battery (to reset everything). The truck was taken into the dealer first thing Monday morning just to be told that nothing is wrong with it.

- Johannesburg, MI, USA

Had been driving in rain all day. Pulled out to pass on two lane highway and check engine light started flashing. Engine started sputtering and stopped accelerating. Had to pull back behind vehicle I was trying to pass. Dealer said I had same problem other ecoboost owners were having and replaced intercooler. It did not fix problem as it has happened 3 more times. Dealer said Ford was "working on a solution". I have to wait for recall and just be aware that problem could occur if conditions are right.

- Jourdanton, TX, USA

I was traveling down a secondary road in rainy conditions at approx 35mph as I pressed the gas to accelerate, the engine lost power and would barely accelerate. Engine light began flashing with what I assume is the infamous ecoboost misfire. The truck is a 2013 with only 13000 miles. Once I stopped briefly the misfire went away and normal operation resumed. There were no other vehicles around but as others have stated this is a problem that needs to be addressed because in different circumstances it has the potential to cause an accident.

- Harleyville, SC, USA

While trying to rapidly accelerate from a slow speed of 20 mph to avoid a possible collision my F150 ecoboost engine lost all power and the engine light started blinking. I had to pull over to the side of the road and wait for the engine light to go off. This is a serious safety issue that needs to be fixed. This is a recurring issue with my ecoboost engine.

- Kentwood, MI, USA

While trying to pass slower vehicles on the freeway my F150 ecoboost engine lost power and the truck started to shake. This situation almost cause a serious accident as traffic behind me had to rapidly slow down to allow me time to pass the slower vehicles and get out of the way.

- College Station , TX, USA

I was traveling on the highway behind a truck towing a big camper. When I got a chance to try and pass him I got over to go around him and went to accelerate and my truck lost all power (check engine light started flashing) and I had to apply brake hard to slow back down to get back behind the truck. Luckily there was not anyone behind me so I was able to get back over. I had to pull over and set and the check engine light finally went out and truck started running fine. I took my truck into Ford and they say nothing is wrong with it. This is a 2013 F150 with the ecoboost 3.5 engine with less than 11K miles. I'm afraid to even drive it now.

- Rittman, OH, USA

While attempting to pass a semi truck after driving a constant speed of 65 in arizonas humid monsoon season, under hard acceleration my F150 had a sudden loss of power along with a very strange shudder and loud revving sound. After I let off the accelerator and pulled behind the semi I was attempting to pass (due to on coming traffic), the truck ran normal. The dealership was unable duplicate the issue. The conditions were different the day of test drive and the truck was not driven at highway speeds for nearly as long. This could be a very serious issue that needs resolved immediately.

The first time the incident happen I was driving about 30 mph on a bright sunny day about 70 degrees out. I tried to go around a car and when pressed the accelerator the vehicle kind of stalled and shook, did not accelerate at all. I let off the pedal and tried again and it accelerated fine. There wasn't much danger involved in this mishap as the other driver and I were the only 2 vehicles on the road for a fare amount of distance. The second time this happened is what really worried me. I was leaving a gas station preparing to cross a 4 lane highway with a speed limit of 55 mph. This time it was morning about 65 degrees and sunny, I rolled up to the intersection and when an opportunity to cross was presented I pressed on the accelerator and the vehicle shook pretty bad and the engine about died. I hit the brake and the engine worked itself out of the shake. That's when I realized this issue is life threatening. If I would have pressed the accelerator and the vehicle brought me to the center of the highway and stalled there is a very good chance I could have been T-boned! and to top it off another issue I have been having with my 2013 Ford F-150 platinum is the bluetooth is rarely capable of syncing to my iphone, so I were to be T-boned the vehicle would have been incapable of utilizing its 911 assist feature and the injured involved in the accident would have to rely on a witness dialing 911.
