While driving the vehicle on a city street it started to accelerate on it's own and I had to slam on the breaks because of it doing that. Again one December 20th 2019 it did it again. I dont know what's causing it to be doing that but I've taking it to the dealership and nothing can be found wrong.

On Dec 9 while taking off from the traffic light driving at around 5mph my truck suddenly did not accelerate.., the stability control warning light, brakes warning light and the airbag warning light came on. I almost got into an accident as I did not expect my truck to suddenly not accelerate. At this time the truck would only drive at 5mph. Drove to the dealer at 5 mph and they cannot replicate the problem. On Dec 10 it all happened again. Suddenly the truck will not accelerate and again almost got into an accident. Today for the third time it happened again. On each occasion the dealer cannot replicate the problem however they did remove codes not pertaining to the symptoms.

On Tuesday 11/5/19, we were traveling on a highway at around 45 mph when I decelerated to make a right hand turn onto a city street. I had accelerated back up to around 30 mph when I cross over a relatively smooth railroad crossing at a slight left hand turn. Immediately the information center on the console start displaying multiple alerts and the vehicle started decelerating. While the engine did not cut off, there was no power to the powertrain and eventually we rolled to a stop on the side of the road. The vehicle continued to fire alerts. The only way to stop them was to turn the vehicle off. The messages still fired so I opened and closed the door. I restarted the vehicle with no problem and the alert messages had ceased. I drove the vehicle back to the house (approximately 4 miles) at highway speed with no issue. We took the vehicle to the dealership then next day (26 miles) with no issue. Fortunately, our Ford pass app had captured all the alerts and, after a couple of days, the dealership replaced a gas pedal position sensor. We picked the truck up on Friday and it worked fine until the next day. We were decelerating from highway speeds on the highway to turn left onto a side road. We hit a small hump where the side road meets the highway and again the alerts starting firing and the truck lost propulsion. Again, the engine did not turn off and the only remedy was to turn it off and back on. We plan on taking the vehicle back to the dealership but would like for Ford to assess this problem as it seems to be beyond the dealership's capabilities to fix the issue. Since several of the alerts represented loss of safety functions including brakes, traction control, powertrain failure, and others we feel this issue represents a safety issue that Ford needs to diagnose and fix. Several of the F150 forums have shown other users having the same issue.
