While under acceleration in traffic, the vehicle lost power, explosion, fire, lost oil pressure, almost got into accident dealership diagnosed it as intercooler collected condensation that got sucked into engine intake causing the engine to explode a hole in the engine block. Intercooler still had over a sip of water in it.

While attempting to accelerate from a stop sign turning right my 2012 Ford F150 platinum 4X4 ecoboost stalled and would not accelerate for a few seconds. I thought the truck shifted into neutral but that was not the case. This has happened several times within the last 3 months and is getting more frequent.

While traveling from Kentucky to Alabama in driving rain my entire trip, truck begins to misfire and lose power in Alabama for the first time since I purchased it new. After letting up on accelerator, truck engine stopped missing, but under strain and on hills it again began to miss fire and engine light began flashing again. Because of power loss and engine bucking, I found a Ford dealership immediately for repairs. They replaced the intercooler and reprogrammed the computer in the truck. The truck did stop misfiring, but seemed to drive a little different. It felt like the engine was turned down and still seemed to miss some during the rest of my wet trip to Florida. Truck seems to drive great in the city under dry or wet conditions now. * it appears the issue is only with extended travel in very wet conditions.

I switched lanes to pass a truck and there was another vehicle in the lane so I stepped on the throttle to the floor and it hesitated then started to die. Then the truck started to shake along with the steering wheel. The check engine light came on and it continued to sputter and shake for a mile or so then it started to come out of the problem. The check engine light is still lit and my aftermarket stereo can pull the check engine codes and they were P0300 P0304 P0306 P0306. It was about 75 outside and the road was dry. This is the 4th time this has happened. The truck now has 26,300 miles on it.

On vacation to ga from md in July of 2012, during a heavy downpour and lost power several times traveling on I-95 towing a boat. Driving about 65-70 mph stopped at the Ford dealer on rt. 1 in fredericksburg va and they did a temporary fix, a piece of cardboard was installed to prevent the moisture from causing problemsonly to be told to go back to our dealer for the part once it comes in all back ordered. We have since contacted sheehy and got nowhere never got a call either that the part was in. Truck gets the worst gas mileage and over the rain we had started to stall out again. Never called and never fixed.now with the rain again and the heat it is doing it again.....

- Greyling, MI, USA

On trip from louisville ky. To atlanta, ga in the rain, truck displayed the shuddering stall caused by condensation in the charged air cooler which gets ingested into engine causing motor to go into limp mode, truck has had two of the three tsb's performed as this is the seventh incident of the same problem since new. When truck goes into limp mode at highway speeds you are immediately at risk from rear end collision.

Since I purchased my truck there has been seven different occasions where I have accelerated to enter an interstate or pass a vehicle and the engine lost power and I could not accelerate. I have taken the truck in and they have replaced parts and said it was repaired. This past weekend I was entering the interstate in a construction area where barriers were on both sides of the interstate. I accelerated to enter the interstate and there were cars and a semi approaching where I entered. I accelerated to get up to speed with traffic and the truck stalled and would not take fuel. The approaching semi could not stop in time and had to swerve to miss me. He missed hitting me by inches and almost hit another car. With the barriers in place I could not get off the interstate when the truck stalled. I have the eco-boost engine and the vehicle is currently at the dealer. They are telling me they can not find anything that is causing the failure. This failure could have caused multiple injuries or deaths had the semi not been able to avoid hitting me or the other cars. I personally feel this is a safety issue with this engine.

Myself and my wife was traveling on a short four lane road when I attempted to accelerate to pass a slower vehicle. My F150 engine shuddered, I let off the accelerator, the shudder stopped. I then tried to accelerate again and nothing. It was like I was coasting, I had no power from the engine to accelerate. I continued to try and accelerate but nothing. This lasted for 15-20 seconds then it started to accelerate normally. This same type of lost of power has happened 3 times since then. The first two times it was raining heavily, the last two it was not. I have read about the issues documented with the F150 eco boost engine and I am sure this is that problem. Unfortunately I read it after I bought the truck!!

I had the tsb (for known surging issue) performed on my truck (2012 super crew 4X4) in may at 25K miles. Everything seemed better, until... this past Saturday, I left the house at 5am for a 7.5 hour/ 350 mile drive from home. It was raining continuously for the first two hours. Sometimes hard rain, but it didn't stop for the first 2 hours. I was driving back country roads with mostly 55 mph limits and rolling hills. Given the weather, type of roads, time of day, etc. I drove gently for the trip, never put my foot in it. Then, when going up a steeper hill that required more throttle than the others to keep my speed up, the truck started hesitating. A lot. More than it ever had before the tsb. And then, just after the hesitation began, something extra occurred that had never happened to it before. The truck started to shudder. This shuddering was akin to driving over road shoulder rumble strips on steroids. As soon as I let off the gas, the shuddering stopped. I gently pushed the pedal, shuddering was back and just as bad. Let off again. It stopped. Pushed the pedal again. It came back. Pushed the throttle once more, and it had stopped. I slowly pushed further on the throttle and it didn't do it any longer. By this time I was down to about 35-40 mph going up the hill. So I pushed down the pedal almost to the floor. The truck kicked down and accelerated with only slight moments of hesitation. Not once did the check engine light come on.. thus, I had a textbook case of exactly what the tsb was supposed to solve, but didn't.

I was traveling South in the outside lane on I 95 (Florida) during heavy rain, approaching a slower moving vehicle in front of me. I changed lanes and accelerated to approximately 70 mph, when the engine suddenly lost power, began to misfire and rapidly decelerated. The vehicle had been traveling in rainy conditions at highway speed for approximately 1 hour. Since I had committed to make the overtaking maneuver and for the few seconds I was unable to accelerate and/or pull back into my original lane as I was traveling adjacent to the vehicle I was overtaking, I realized that there was another vehicle fast approaching me in the inside (fast/over taking) lane. Luckily the driver was observant enough to release of the impending collision a head if he did not take evasive action and slow down. After a few seconds I was able to pull back into outside/slow lane. This loss of power and misfire continued for another 45 minutes, up until I exited the highway and drove to my local dealership.

This write up is for a 2012 Ford F-150 truck with the 3.5L ecoboost V-6 installed. Jan, 2013-while driving on I-24E, I was pulling out from the rest stop, just North West of exit 1. I went to pass a 18 wheeler and my truck came "unglued". it practically died in the passing lane when I pressed the gas peddle. It shuddered so hard; I didn't think I would be able to get off of the road before it died. It was missing and shuddering like crazy. I pulled off exit 1, shut the truck down and restarted. It ran ok without that same thing happening on the way home. I had a pretty descent "miss" in 6th gear, running down the interstate at 75mph. Something very strange happened here. It was the first issue I've had with my truck. Although I've noticed recently the mpg is down by 2.0 mpg or more for the last three weeks, and this from refueling at different locations, and the same driving style. Ford applied the tsb to reprogram the PCM/tcm to latest level, installed a deflector shield on the intercooler and possibly replace the drivers side catalytic converter if needed. July, 2013- this weekend while driving on I-65N, I had the same issue happen. The truck now has 17,000 miles on it. I've had the vehicle back into my local Ford dealer four times for this issue. The vehicle exhibits this issue when it's rainy and has been driven in the rain for several (50 or more) miles. In heavy traffic this is a very dangerous issue. The vehicle goes into some type of safe mode and will barely limp off the road. If this issue were to occur while crossing a four lane hwy, and sputtered one could be seriously injured or injure someone else.

My 2012 Ford ecoboost with shutter, stall, and shake violently on the highway at dangerous speeds and wet, moist, or humid conditions. It is very unsafe and remains consistent even after Ford "tsb" with replacing the cac. Engine throws misfire codes as well in cylinder 5.

- New Orleans, LA, USA

While traveling to Florida from Tennessee we had stopped at a gas station. While pulling out into traffic and accelerating, the truck started shaking violently due to misfire indicated by flashing check engine light. The miss was so bad that I immediately had to pull over. I shut the engine off to clear the on board computer. The truck ran fine afterward, but the check engine light stayed on. This was a bit scary as we could have been hit due to the rapid loss of power while merging into traffic. Weather conditions were very rainy. We had driven thru rain for ~7 hours off and on. I believe this to be a known problem that Ford has yet to fix with condensation in the turbo's intake on the V6 ecoboost engines. I am headed to the dealer when I get back in town.

- Hixson, TN, USA

From stoplight to begin approach up a long/large bridge truck shuttered violently, lost power, did not show any codes, seemed to be in a "safe mode" as it did not stall but would not accelerate and lost speed despite throttle to floor or at any position to regain power. Weather was nice, not raining or overly humid.

- Denver, NC, USA

Having issues with the ecoboost accelerating upon take off or getting on to road ways numerous times I have come close to getting hit because of no power upon accelerating now this has been going since purchase new with only 116 miles and purchase date 3-17-2013. The dealer says this is normal operating condition for the vehicle to have lag time before power.my feeling is if you are sitting at a light and you give the vehicle gas the vehicle will move slow and then do a sudden acceleration and could cause death or injury to someone unsafe truck. Now I'm having issues with the driver window not going down or when it is down will not go up they say this is normal operating procedure Ford has some issue and they need to be corrected before someone gets killed or hurt bad.
