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.

After a prolonged period (8+ hours) of driving at highway speeds in frequent rain the vehicle shuddered and stalled (without completely dying) while in a passing maneuver. The service engine light flashed multiple times then went out. As a consequence of the power loss my vehicle was unresponsive to accelerator input and resulted in compromised safety between two rapidly converging vehicles. After approximately 10 -15 seconds the engine resumed normal operation.

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 2nd time today, I've had this problem and is the 4th episode of the same problem. This is a flex fuel 2013 Ford F-150.this is beginning to be a big concern, as stated I was only going about 10 mph, since I was in a shopping center getting ready to park. The engine usual cranks after I come to a complete start and turn the ignition off. I need this fixed asap. I've got a trip planned.

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. I thought my nuckles were going to part since I had to control the vehicle and not cause an accident. I am schedule to take in back to keith hawthorne Ford on Tuesday, June 25,2013--there phone number 704-825-5186-service person- will

On this new F-150 with eco boost engine, the engine now has shut down 2 times the last 2 days on June 12 and 13, 2013. The engine oil light came on. I was only going 20 mph when this happened both times since I was stopping at the stop sign 3 blocks from my house. On the highway with the engine in cruise control at speed of 60-65 mph the transmission goes from 6 th gear to 5th gear alot.

Traveling on the interstate during heavy rains. Traffic in my lane stopped. I tried to change lanes and accelerate briskly. When I tried to accelerate, the vehicle started to shutter and the engine power died. It seemed to go into limp mode. The check engine light flashed several times. The vehicle would not accelerate and left me hanging in the travel lane with faster traffic almost causing a crash. Vehicle is one week old and has approximately 600 miles on it. The engine is the Ford ecoboost 3.5L V6. The vehicle had to be turned off and restarted to get it to drive normal again.
