"On thursday evening, 11/22/2018, i was coming to a stop at a light on a city street (speed limit 35) when my car stalled without warning. moving at most 25 mph when it occurred, the oil and battery lights came on as i slowed. i tried accelerating slightly to diagnose the issue, and nothing happened."
"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."
