2011 Ford F150 equipped with 3.5L turbo charged engine traveling at 65 mph began misfiring and suddenly experienced a near total loss of power, causing the vehicle to slow to 25 mph quickly. The vehicle was traveling on a two lane highway with no shoulder and no place to pull off the road. This incident did not pose an immediate threat to car or driver, but under other conditions such as overtaking (passing) slower traffic, the sudden and near total loss of power could be disastrous. After quick research and consultation with the Ford service center where I purchased the truck, I have learned the vehicle entered into "limp" mode to protect itself from mechanical damage. I have also found that this problem has long been acknowledged by Ford Motor Company and has been the subject of a few technical service bulletins. Also to the best of my knowledge, Ford, through this series of technical service bulletin's has failed to provide a permanent solution to this problem. I am filing this complaint in hopes that the NHTSA in cooperation with Ford Motor Company can provide a quick and permanent solution to this problem before someone is seriously injured or worse due to an engineering flaw on a motor vehicle.

Event occurred 3 times over a period from 27 Oct 13 to 21 Nov 13, decelerating while towing a trailer. Speed varied all three times from a high of about 60mph, to a low of 45mph. Message center would turn orange and display a wrench symbol, while the engine discontinues producing power. After pulling over, simply turning the vehicle off, then restarting, everything appears normal again. Two Ford dealers "found no codes", and were unable to further diagnose the issue. The second dealer attempted to collect data via an onboard computer as well, but the event wouldn't repeat while the device was installed, nor was I towing during that time. One of these events occurred on a two lane road with no shoulder available. Traffic had to stop until I restarted. Dangerous at best. The third even occurred going up a one lane freeway flyover. I was able to coast past the bridge structures and onto the shoulder, however, this occurred during rain, and multiple other vehicles had to make accident avoiding maneuvers, including tractor trailer rigs. Very dangerous. I have replaced the vehicle.

The contact owns a 2011 Ford F-150. The contact stated that while driving 70 mph, the advanced track system warning light illuminated and the turn signals became inoperable. The contact took the vehicle to the dealer for a diagnostic test where the dealer stated that the steering gear assembly module malfunctioned and needed to be replaced. The dealer replaced the entire steering system. The contact called the manufacturer and filed a complaint. The failure mileage was 40,487.

Repeated misfires, and loss of power when accelerating, engine lights flashes. This has happened 2 additional times since the first incident. The last 2 times I narrowly avoided accidents at highway speeds. The inter-cooler has been replaced and now they say I need plugs. I need help to fix this problem.

Attempted to pass a car. Speed at time of attempt was 55mph. Time 2:20 P.M. and partly cloudy. Two lane road but had plenty of time to pass or an accident could have occurred. Pushed down on accelerator and the engine actually decreased speed/significant deceleration. I let up on gas pedal, maintained speed then was gradually able to pass. Think the turbo had stalled. This had happened once before, shortly after I purchased the truck. At that time I was merging onto interstate and it stalled out, for a shorter duration. After the July 31 incident, I took the truck to Ford to inquire about the issues some owners have had on the eco boast engine, which I have. No codes appeared so I was told they couldn't do anything. Then talked to regional customer service and got the same story. I am very concerned as I use the truck to tow a 26' trailer. When the eco boast turbo works, I have plenty of power to merge or pass. The above experience was scary and I did not have the trailer behind me at the time. Now I feel I can not reasonably depend on it to work as it should. I think it is the turbo but it could be the electronic gas pedal, or the transmission but I really do not think these are the issue. Please help! thank you.

I was traveling in the righthand lane of the East bound side of I24 around manchester, tn. My speed was approximately 65-70 mph. I suddenly came up upon slower traffic in the same lane and signaled to pass the slower traffic. As I looked in my mirrors for traffic behind me I noticed another vehicle closing on me in a hurry. I depressed the accelerator to gain speed and make the pass. The vehicle lurched and the motor suddenly shut down and wouldn't accelerate in the middle of my pass. The vehicle behind me locked their brakes and managed to slow their vehicle down before possibly colliding with me. I let the slower traffic on the right pass and signaled to get back in the right hand lane. This has happened twice to me and I think there is a real possibility this could endanger lives and property if not corrected. My 2011 Ford F-150 is equipped with the 3.5 liter ecoboost V6.

When I'm accelerating the engine stalls, I may be leaving a stop sign climbing over an overpass or passing another slower vehicle. Seems to happen more often about 40mph to 70mph.

This is very disappointing to have to experience so soon with a brand new truck. The location of this wiring harness is in an area that unless you have side steps and maybe even then, is not protected. Even then the way the wiring harness comes out from within the wheel wall makes no sense. I'm attaching a few pictures so you can see what occurred. Luckily, someone saw the wire dragging and told me before it was too late. I put up the harness and taped it to hold it up. This could have had a horrible outcome had the wires continued to shred or make contact with one another.

My new Ford F150 has recurring issues with the sync system. We drive down the road, hang up the bluetooth connected phone and the radio will begin playing at full volume and the steering wheel controls stop working, or you will be starting the car up and the air conditioning will be full blast or you will start the car and you wont have any radio/cd player/ media controls working at all. My Ford rep says that Ford does not have a fix and they don't expect one until maybe the first quarter of 2011.

From a dead stop I accelerated to turn into her driveway the engine hesitated and stumbled it sounded like you had thrown a handful of marbles inside the intake the engine made a funny noise then died after getting it restarted the check engine light came on upon returning the vehicle to the dealership I found out it had melted the intake manifold sensors and part of the throttle body away Ford has no idea what caused this the truck is also been plagued with electrical problems. Apparently it came real close to an engine fire the truck is still broke down at the dealership since August 5, 2011.
