Vehicle would lose all ability to accelerate or use any type of throttle control while driving on highway. Had to continually drift to a shoulder on the highway to turn off vehicle because the throttle body went bad. Extremely dangerous, vehicle became inoperable and unsafe to be on any roadway.

I drove my F-150 eccoboost truck to the snow, same area I have been hundreds of times and suddenly smoke burst from the engine, then flames shot out around the hood, popped the hood and fought the fire for half an hour, it kept restating. It stranded myself and children, and we had a harrowing experience that was pretty dicey. Ford had just put in a new engine, at my cost, +14,000.00, after the timing chain failed. They would not repair it at their cost, even though I have copies of the fault codes from before the failure of the timing chain that destroyed the old engine. The new one had under 10,000 miles on the new engine, probably about 5,000 miles on it. We had driven on the relatively flat grade mainline road, and drove up about 0.8 miles, climbing maybe 400 ft elevation over that distance. I was in the process of turning the vehicle around when the engine burst into flames. It was on a gravel road. We had traveled from home, 35.2 miles.

While traveling on the highway we saw looked out the rearview mirror and saw white/gray smoke coming up from between the truck bed and the cab of the truck. We exited the freeway. While exiting the white/gray smoke turned to black then flames shot up. We pulled over and got out as the flames continued to grow. We attempted to put out the fire but it grew very fast. The back glass exploded and the entire cab and front of the vehicle was engulfed. 911 was called. Firefighters arrived and put out the fire. The vehicle and contents were a total loss. The fire department reports states that the fire was caused by a mechanical failure in the engine compartment or under the passenger compartment causing flames to show from the back of the vehicle and causing heavy damage to the front of the vehicle and passenger compartment.

Electronic throttle body. Wrench appearing, truck in limp mode, no power when accelerating, even while in park. Truck has 31,000 miles.

- Trumbull, CT, USA

Engine failure - limp mode - this is a known problem with the Ford F-150 ecoboost that Ford and NHTSA have yet to address/ issue a recall. I have owned this truck for less than a month and it has twice now gone into 'limp mode'. merging lanes on the highway and the engine failed, a complete loss of power and ability to accelerate. I was able to avoid a terrible accident and get to the side of the highway. After reading hundreds of complaints online from other F150 owners I was able to see that the dealerships and Ford know about this issue, but have yet to address it. I checked the spark plugs and they were from the factory, yet gapped incorrectly as others have stated. The throttle body also will have to be replaced. This is horrible practice by Ford and NHTSA should address the thousands of complaints on the issue. This is going to kill someone eventually. I will be getting rid of this truck immediately and getting a reliable truck like I had previously.

- Morrisonville, NY, USA

I was merging onto the highway and when I went to accelerate my truck lost all power and decelerated and a wrench icon appeared on the display. I pulled over luckily safely without causing an accident turned my truck off and back on and did not experience this issue again. This is the 4th time this has happened. Hopefully my family does not get harmed with this vehicle it is only a matter of time until someone does with this issue happening.

- Cuba, NY, USA

Bought the vehicle with less than 14,000 miles. Before 30,000 miles had a small rattle when starting. Always followed scheduled maintenance. At 92,000 miles code P0016 comes up. Took it in to get looked at was told timing chain is stretched and all 3.5 liter eco boosts from 2011 to 2014 have defective timing chains but Ford hasn't recalled it yet. Apparently they have sent bulletins to technicians on it, admitting design flaws. Why no recall!?

- Tomah, WI, USA

This vehicle has shut down during operation on several different occasions. The first, was a minor repair. The second, caused over $11,000 in damages, and now it has happened again. Each time it occurs, the loss of power causes a decrease in the ability to steer and all systems shut down. With our children in the vehicle, we have been in fear for their lives as we have had to quickly steer the vehicle out of the lane of traffic and hope that we are able to come to a complete stop.
