Last week, my 2017 ford expedition experienced a situation where while driving the vehicle suddenly stopped running. I was forced to coast over to the side of the road when this happened, as the engine was running but my accelerator pedal was not operating and the vehicle would not move. Fortunately, after shutting the vehicle off, I was able to restart it and continue driving. In the space of 24 hours this happened six (6) times.
