"Rough idling at stopping position, stalling, cutting off in traffic, check engine light, code p0507 idle air control valve throttle body."
"While driving on the highway my 2016 ford focus stalled without warning and would not start until after having it towed. When I go to the gas station after filling the gas tank my vehicle is either hard to start or doesn't start until after waiting a while. This happens often."
"I believe it was the fuel system that failed. The safety of myself, my child, and other drivers was at risk. The Ford dealer I spoke to said my vehichle is not affected by the recall that causes this issue (18S32). The auto center I took the car to could not reproduce the incident."
