I was driving in humble while it was raining and I accelerated to get over to the next lane. When I tried to accelerate my truck started to lose power and the engine light started blinking and the engine shuttered. I then let go of the gas pedal and pulled over and killed the truck. When I cranked the truck bank on the engine light was off and the truck drove fine.

The truck I bought has been shaking since the day I picked it up and brought it home. At 55 mph the truck has a distinct wobble. It has been back to sharpnack Ford twice for the problem and I was told they drove four other trucks on their lot and they all do the same thing. Also they took the tires off of mine and swapped them with another truck with the same result. I was told they took the drive shaft apart and rebuilt it, still no fix. After two times back to the shop, I was told by the head mechanic that Ford told him no more repairs will be done to this truck. I can see the bed wobble as I am going down the road and am confident this is where the problem is. Ford is not willing to do anything about it claiming the frequency is within specification limits. I have also driven a 2012 and a 2013 and both of them do the same thing. I'm not sure this is a problem that will cause imminent danger to anyone unless you factor in the"road rage" someone will have after paying 45K for a brand new piece of garbage that the manufacturer refuses to do anything about to fix.

I took my 2013 Ford F-150 with the ecoboost engine on a week long vacation down to South Texas (approx. 1200 miles or 17.5 hours one way) it was sunny and warm the entire trip down and the vehicle ran great. However on the way back up to Iowa in was raining as soon as we left and only let up raining for 20 min increments the entire way home. About 5 hours in we pulled off the interstate to get gas and eat. We got back in the vehicle and proceeded to get on the on ramp and return to the interstate. I was going about 40 mph with smooth acceleration when I gave my truck a little bit of gas to merge into the 75mph traffic. My truck did not move, instead it continued to go 40mph and revved up to redline. I had to let off of the gas completely and put my foot back on it and slowly climb up to 65mph. The truck started shaking horribly and my check engine light started to flash. After about 45 seconds the check engine light stopped flashing and the engine stopped shaking. I then could make very slight speed increments. I could not however step on the gas to pass somebody without the truck revving up to redline and shaking again. This happened every time I tried to accelerate quickly the rest of the way back (12.5 hours). The truck runs great until it is introduced to 70mph interstate driving in heavy rain for long periods of time.

At or aroung 500 miles on my brand new 2013 Ford F150 svt raptor a message come up on the 4.2 incd lcd that read "check fuel inlet". I was at a gas station putting gas in my truck and while I was pumping gas I called harbin Ford and spoke with a service rep. And told them what had come up on the lcd. The service rep. Told me to open the back door and look under the back seat on driver side and there should be a white funnel looking object about 6 inches long. I pulled up at my home and parked my truck under our carport which has 2 open walls and another to enter the carport. On the North end the carport is supported by 3 steel poles which holds the carport up which is attached to our house. I placed my truck in (P) park and left the engine running, my mother was outside about 10 feet from my truck. And I thought before I got in my truck that maybe I should try the funnel deal mentioned earlier in this description. So I just opened the back door because the front was already open because I left my truck running and it was in the (P) position but I got the funnel and opened the fuel door and started sticking the funnel in and out repeating several times. And about the 2nd or 3rd time sticking the funnel in and out of the fuel inlet my truck acted like someone had placed my truck in reverse and it started coming in reverse. My mother seen this and she screamed at me to get out of the way and I just seen a opening between the doors and I somehow ended up in the driver seat and I hit the brake and to disbelief I looked at the driver side door and it was almost ripped completely off and the driver side fender was also crinkled up from the door catching on the last pole exiting our carport. I looked over at the auto transmission and the truck was still in park?

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.

- Charlotte, NC, USA

I drove my F150 for a short distance of maybe 3 miles, shut it off, entered the post office for approximately 5 minutes, drove the truck across the street for a distance of maybe 1/4 mile, shut it off and went into a business for maybe 5 minutes. Upon starting the truck to return home it would not shift into drive. I looked at the instrument panel and saw the rpms to be over 3000. I did not hear the engine revving due to ac blower noise. I checked the accelerator to see if anything was touching it and nothing was near the accelerator. I shut the truck off, restarted, and it performed normally. Other issues: 1) several months ago the radio would not turn on while driving and when I shut the truck off the outside temperature display along with the date/time display was flashing symbols instead of displaying alpha-numeric characters. Upon restarting the truck the display returned to normal and the radio functioned normally. 2) when applying full throttle the engine basically stalls which can be somewhat hazardous when entering an interstate highway with a short entrance ramp and heavy traffic. I mention all of these items because in my opinion they would point to computer issues on the ecoboost.

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.

I purchased my 2013 Ford F-150 ecoboost in December 2012. The first incident occurred in approximately March 2013. It was raining. I was accelerating from a stop light where I had made a complete stop. I could not gain speed very well. The engine light was flashing. The engine was sputtering/popping and the whole truck was shaking violently. The same has occurred ever since on more than a dozen occasions and at various speeds. However, each time was while it was raining. Never has had a problem in fair weather. I experience a total loss of power, many times when on the interstate or while trying to overcome a vehicle. The front-end lurches, I lose speed dramatically, the engine shakes violently when I accelerate. The engine sputters and sounds like it doesn't know whether to choke out or blow up. The engine light flashes for approximately 1 minute each time. Almost sounds like a misfire. Happens several times during one trip often, but always when it rains. Continuous occurrences and beginning to become more frequent. Have taken my truck to 2 dealerships, neither of which can detect any dtcs or any other problem. Offer no advice other than to keep driving it until the engine light stays on permanently. They have no idea what causes the problem. I am really afraid that the problem may result in a motor vehicle accident. Have not had one yet, but have a had a couple of incidents where I had to pull over to avoid an accident. Problem is so persistent that I am considering trading vehicles, especially since I have been offered no remedy for the problem. I have also filed a complaint with Ford Motor Co. On 07/30/2013.

While driving South on hwy 87 South toward southport, nc near sandyfield, close to the hyw 11 intersection, I performed a hard acceleration to pass a slow moving vehicle when I experienced a sudden loss of power immediately followed by shaking. If the vehicle I was passing was going faster than 50 mph I would not have made it around him. While I did not stop, I did slow the vehicle to under 50 mph to which the engine light stopped flashing as did the shaking. The weather was partly sunny with high humidity. Road conditions were dry.

This is the 5th incident with the same problem, but worst now. I had this truck at the Ford dealership on Monday June 17,2013. They said it will be hard to diagnosis without a fault code. How is it they can tell me how fast I have been driving for the past month, but the inboard computer cannot tell Ford technicians what is wrong.the engine cut off again for the 5th time, but this time it would not start. The instrument showed 2 icon's this time, a ( wrench and check oil ), I'm sorry but the wrench indicates I believe something to do with a rear end on a 4 X 4 truck, sorry this is only a 2 wheel drive vehicle. I tried the ( 2 ) recommendation in the instruction book and when turned the ignition to start it only tried for less than 3 seconds, then the power to the ignition went blank. I tried for 30 minutes, then called Ford road side assistant for a tow truck, which was dispatched within a hour. I had already called Ford Friday June 21,2013 for an appointment for # 3 & 4 with the engine cutting off. I then called Saturday morning and asking then for a better appointment, they gave me one for Monday 6-23,2013 instead of Tuesday 6-24-2013.I badly need transportation this next week, I'm going to ask Ford for ambulance service this next coming Friday June 28,2013, I am a disabled senior veteran and having hip injections next Friday out of town at the veterans hospital and need a care giver, since I won't be able to drive after the procedure.Ford this is beginning to be a very serious condition when driving and probably cause accidents very soon. Lets get the problem fixed or order me a new truck because of North Carolina lemon law.

This is the 3rd time that this new F-150 truck engine suddenly has cut off. I was at the Ford dealership in belmont, N.C on Monday June 17,2013. They said they could not find anything wrong. They then said they put in a new update code. I now have only drove about another 50 miles since Monday. It cut off again while I was driving about 30 mph on a busy charlotte, nc street.

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.
