While driving, rear wheels lock up for a few seconds, then truck shakes and has no acceleration power. This is happening at least once weekly now with loss of power lasting from 10 to 45 seconds.

We took the truck to the local dealership and had them look at it . They did a service order and came up with nothing wrong. We took the truck home and the problem remained. The truck was taken back 4 or 5 more times for the same problem and the…

Dozens of incidents of misfire and loss of power upon acceleration sometimes resulting in severe shaking and flashing of engine light. Has nearly caused accident on 2 occasions where i was unable to maneuver through traffic. In shop 3 times, first 2 times technicians supposedly could not replicate problem (very easy to replicate if trying to do it). Most recently advised that i might need a "tune-up" and oil change.…

First, this has happened many times, i would guess at a minimum 20 times over the past year or so. The date an mileage listed are estimates about the first time this happened. What usually happens is that i am waiting at a stop light and my vehicle will shutter as if it were about to stall and will then get a small burst of power and jerk forward slightly. As i mentioned, this has happened multiple times, and i…

The vehicle lost acceleration in a major highway and started to smoke. My wife and i were almost killed when we tried to move off the road by a tractor trailer. There was no way of controlling the vehicle with no acceleration and major vibration of the truck. I notice that many others are having problems with the ecoboost f150 engines as well. *tr

This loss of power has happened multiple times since then. At first on hard…

Lack of acceleration - i had been driving on an interstate in heavy rain. I then stopped for gas. After stopping for gas i went through a toll booth and re-entered the interstate. The pickup would not accelerate at a normal rate. I could only go 30-40 mile per hour for the first mile or so then it returned to normal. The computer set a code. After returning home i took the truck in to the ford dealer where i…
