NHTSA Complaint #11548582 — 2017 FORD F-150

I was driving at highway speeds (60mph) in congested traffic on a road with a steep incline with no shoulder when the truck suddenly went into limp mode when it downshifted. The engine went to idle and I had to coast to the far edge of the right line before coming to a stop. Multiple cars around me had to take evasive action. This could have been catastrophic if I had been crossing an intersection. Similar reports online indicates issue with the Electronic Throttle Body which creates an error that causes the truck to go into limp mode. Turning the truck off and back on again reset the condition so I could safely pull off to a side road to further evaluate. The limp mode feature is entirely unsafe and places the safety of the vehicle's mechanical components over the safety of the occupants. I would rather damage or destroy my engine in the process of safely exiting the roadway than come to an unexpected stop in an unsafe location.
