I was accelerating up a small hill. I reached 30mph and stopped accelerating. The truck continued to accelerate slowly at around 2000rpms after I took my foot off the pedal. I shifted the truck into neutral and the rpms slowly increased as it was no longer under load. I tapped the accelerator and they surged up to 4000 where they were capped by the computer. I used my brakes to come to a stop in the middle of the street and turned the truck off. I waited a few seconds and started it back up. The tachometer showed 1000rpms and then down to 700-800rpms. I continued home. This has happened 5 other times with this vehicle. I am still troubleshooting the problem, but it is not caused by floormats and I have ruled out the cruise control being part of the issue. The last time it happened, I engaged/disengaged the cruise control while the truck was accelerating on the interstate with no change in behavior. It appears to be mechanical to the throttle body or a computer malfunction somehow. It is a difficult problem to replicate and does not happen every trip. I am going to inspect/clean the throttle body and clean the mass air intake sensor. I haven't ever had a vehicle act this way and think there is a major problem if you have to turn a vehicle off to reset it. Losing power-steering/brakes is the problem with doing this while the vehicle is under way.

I was on the highway and when I attempted to pass a vehicle,when I floored the gas pedal the truck lost all power for 3 to 5 seconds almost causing an accident. It has been that way from the day I bought it until present. When I questioned the dealer on the lose of power problem I was told nothing can be done about it because it is a normal issue with fly by wire accelerator.

While driving the vehicle engine lost all power and when I pulled over to the side of the road the engine died. Tried restarting the engine multiple times, and it would start but only run for a few seconds and then die. Had it towed to the local ford dealer and they could not replicate the problem. Have had the same issue 4 more times since then. Vehicle engine dies but the last few times has restarted. Took it into the local ford dealer again and again they could not replicate the problem.

The fan blower speed control stuck on high only and was replaced 09/2011. The vehicle kept stalling out upon deceleration going down the road. With loss of power steering and power brakes when this happens. Could be going 30 MPH or 60 MPH. When get motor is started again it usually runs rough. The left oxygen sensor code was on so this was replaced. 11/2011 the fuel gauge also stopped reading fuel in the tank when this happens. Replaced fuel pump in tank, fuel filter, fuel power module, all was fine for three weeks. Truck dies 8 times today and all the same problems are back. Engine light on, fuel gauge stopped working, truck runs rough for awhile when restarted then clears up. Engine light now stays on and fuel gauge will read 1/2 tank when it is full. 36 gal tank. 11/22/2011.

While negotiating a right turn on a busy intersection, I heard a couple of popping sound from the engine compartment. After that, I lost power steering on right turn and almost ran head on in an oncoming vehicle from the opposite direction. I have to slow down to a crawl because I have to hang on to the steering wheel to negotiate the turn. The other driver has to stop to let me get back to my lane. Everytime I negotiate a curve on hwy 160 from pagosa springs to colorado springs, I have to slow down to about 45 MPH to negotiate the curve. It felt like I'm working against hydraulic pressure everytime I steer to the right. Left steer is a bit hard but not as hard and almost impossible to steer to the right. The was informed by the dealer that the power steering gear box was defective. This incident of loosing steering on a busy city street could have resulted in a serious accident.
