2011 Fusion w/ 3. 0 liter 6cyl. While traveling at approximately 50 mph the engine suddenly bogged down. I pressed the gas pedal and nothing happened. I was able to pull over to the side and the engine was still running. A wrench light came on. I put the car in park and tried the gas pedal again with no response. I turned the engine off, waited a few seconds, then turned it back on. I was able to drive home, then to the Ford dealership with no incident. I was told that the problem was the throttle body which is on national back order. Ford would not cover the repair even though car was just over the warranty mileage limit. I found out that the NHTSA started an investigation on this issue in February 2013 and Ford is aware of the multiple complaints of this same problem. I was lucky no truck was behind me since my car slowed quickly and suddenly with no warning. The internet is filled with complaints of this same issue. Please do something before someone is killed!.
