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.

I was driving my new 2013 F150 ecoboost in the rain and I tried to pull to the left to pass a slower car on the highway. As I went to give it gas, about 90% throttle, the truck felt like it hit a brick wall, stuttered and started shaking. The check engine light came on and I was unable to drive the car about 55 mph. If I tried to drive past that it would just shake. The truck had no power. I drove it like this for about five minutes and then the check engine light went off and everything was ok. On the way back about a week later, once again in the rain, the same thing happened. Since then I have tried to duplicate this in dry conditions and the truck performs perfect. Only when it is wet outside does this problem happen.

Just bought this truck for a great deal of money. This has happened several times, with both my wife and I. driving at low and higher speeds trying to merge or pass another vehicle. As we apply the accelerator to pass or merge there is a lose of power and the truck almost stalls. We have almost been in 6 accidents because of this issue. I took my truck back to phil long of Colorado springs, co. And was told I was lying and they have not had any other complaints and they could look at it for $150 as my truck is brand new and still under warranty, im not happy I cant drive my truck safely and feel like Ford has let me down. Don't seem to be getting any post sale customer service. Please help.

While accelerating, vehicle lost power and started shuddering with the check engine flashing. Could not accelerate while the light was flashing for about 20-30 seconds. After light went out truck started driving normal again.

While driving in rainy conditions at 55 mph, the driver accelerated which kicked into passing gear. At this time the steering wheel began to shake violently, the vehicle lost all power (though remained on) and decelerated to about 45 mph on it's own. The check engine light began blinking and remained lit for appx 1 minute. Once it went off the vehicle regained normal operations. However, when attempting to accelerate again the same issue occurred. The next day in dry conditions the same situation occurred when accelerating quickly to pass only this time the check engine light stayed on. The same situation has not occurred again, though the light remains on. It is scheduled to go into the dealership tonight.

While merging onto a highway via an on ramp in rainy conditions I was almost involved in an accident when my 2013 Ford F150 ecoboost equipped truck lost power and would not accelerate. I was forced to the shoulder as the approaching tractor trailer was unable to stop in time and the impending collision would have caused serious harm to my family. The check engine light flashed for a few moments as we drove slowly on the shoulder and then it went off. No further highway travel was used following this potentially catastrophic incident due to the rainy conditions. One additional incident occurred with the truck one month prior but did not result in the check engine light. When pulling out of a parking lot onto a busy street the truck hesitated for a few moments before finally accelerating. When the truck finally responded a large smoke cloud appeared behind the truck and the engine revved much higher than normal. Until the recent event we thought it was an isolated incident. There was no rain or excessive moisture in the air on this particular day.

Reduced engine power during hard accelerations. Experiencing misfires at highway speeds and when pulling out into intersection. Was almost hit by oncoming vehicle in intersection because truck lost power and speed in the middle of the intersection, truck was called on fast to make a lefthand turn at the gap in traffic and lost power. Vehicle was purchased new on April 13, 2013. Ford dealership ran diagnostics and determined problem was due to oasis special message number 32227, "intermittent stumble/misfire on acceleration". Ford said there is no fix yet "engineering is investigating, continue monitoring for updates".

May 22, 2013- while driving South on I-55 and merging onto I-12, I was traveling approximately 35 mph when I gave the truck gas to accelerate into oncoming interstate traffic of 70+ mph. My truck completely went limp and I could not accelerate at all with the check engine light coming on. I was in real trouble at this point so I pulled off with one tire in the grass to avoid a serious accident and potentially being killed. Approximately 1 minute later the truck regained power and I continued to my destination with the check engine light going back off. May 23, 2013- I called Ford dealership where I bought my vehicle and they explained to me that nothing was wrong if the warning light went off. Stating the system does this as an environmental precaution? May 28, 2013- I was traveling in galveston, tx at 25 mph when the check engine light came on again. I did attempt to give it gas to see if the same problem was occurring and it once again would not respond with the check engine light staying on permanently this time. I parked my truck for work until June 11, 2013. I took a picture of my dash to document the warning light. Called Ford dealership @ 7:20 a.M. on 6/10/13 explaining my situation. He stated that over the phone it sounds like the inner cooler. He explained to me that it is not dangerous and not to worry. He said the part was an updated part and they would have to run diagnostics to know the problem for sure. Dropped truck off at Ford dealership @ 11:10 a.M. on 6/12/13. Received phone call from Ford @ 3:20 on 6/13/2012. They told me that it was not my inner cooler because my truck has this so called updated inner cooler and they replaced my catalytic converter. They assured me this was fixed and would not happen again since the system was updated. The power loss happened two more times since and has me really worried to drive it.

6/08/13 while traveling from kingsville to rio hondo at 6 am for a fishing trip, I accelerated hard to pass a semi-truck. My F150 shuddered violently in the back end, and I felt a significant loss of power. The check engine light blinked excessively before extinguishing. The truck resumed normal operation fairly quickly, within 5 sec. I continued to my destination with no further problems, making sure to limit my speed and make no more hard accelerations. The weather was rainy and wet conditions. I intended on investigating this issue once I returned home. 6/09/13 the truck had been parked and not driven until my departure on sun, 2 pm. On my way home I was forced to accelerate quickly on hwy 77 on ramp from fm 107 to keep up with traffic. The truck once again shuddered violently and the A/C began blowing hot air, the loss of power was much more significant than the last episode and I was forced to pull onto side of hwy 77 to avoid being struck by traffic behind me. The engine light blinked and continued to stay on. The truck resumed normal operation; however the length of time before that happened was much longer than before. I was certain I was going to be stranded and it was necessary for me to take emergency measures. The weather was hot and dry.

When accelerating the engine shut off without warning. After the dealer provided service for this issue, the engine shut off while decelerating to a stop and again while accelerating from this stop. Most recently the engine has been very sluggish at times while attempting to accelerate.

While driving North on I-95 in Georgia at 65 mph, I attempted to accelerate. The truck began to shake violently, lose power, and the check engine light illuminated. The weather at the time was 70 degrees with moderate rain. I had been driving for approximately one hour at the time of the incident. I had to pull over to the emergency lane and shut off the motor. The engine restarted ok. I did not attempt any more hard accelerations. I had no more stall problems. I took the truck to the dealer where they found a misfire code, but had no explanation or fix to prevent the problem from happening again. This is an ecoboost vehicle.

2013 F150 XLT w/ ecoboost 42K cost, had to accelerate to get out of the way of a potential accident and the engine stalled started missing barely missed totaling the truck had to plow in to a grass median to keep from being hit. I was able to restart the truck and get it home and have not driven it since. I am so disappointed. If this is not a safety issue I don't know would be, this is scary stuff.

Upon hard acceleration to pass on highway the truck lost power check engine light continually flashed and shuttered when attempted to give truck any acceleration. After a few minutes of driving on shoulder to get to safe exit vehicle seemed to reset and regain all functions and power.

Vehicle is getting way below estimated mpg. Truck is barely getting 16 mpg while the false advertisement says the truck will get 17-21 mpg. This is a brand new truck and has those far shown false advertisement in gas mileage. Along with the mpg, when in cruise control the transmission down shifts all the way down to 2nd gear while driving at 50 mpg leaving the rpms at a high rate when it down shift. There is something wrong with the way this truck down shifts in cruise control. This needs to be looked into as this is not the way a 50K plus truck should be driving or the false representation of the mpg that Ford has claimed. If I had knew the mpg would have been this bad I would have considered a different vehicle.
