I was driving on a main thoroughfare going about 45 mph when my vehicle lost all power and slowed down to about 2mph. The car began sputtering and shaking so I had to immediately get off the road and turn the car off. I waited for a few minutes and started it again, but it would not go over 2mph. A family member happened to be behind me and had to help me get off road with traffic passing by us. He thought perhaps I had water in the gas so we bought an additive to see if it helped, and it seemed to work for about a week and a half, but then it happened again two more times. This time the service engine light came on as well. I went to an auto parts store where they tested it and got an error code of p2111. I had to go the Ford dealership where I was told that the throttle body needed to be replaced. I have a friend who had this exact same issue with her Ford Fusion just a few months back. She paid over $500 to get hers repaired and I had to pay about $400 to get mine repaired. I understand that this seems to be an issue, and I believe Ford needs to issue a recall.
While driving on I-95 south approximately 65-70 mph in moderately heavy traffic, at exit 180, the car sounded like it dropped out of gear while accelerating. I was able to merge to the shoulder of the highway. The car continued coasting and the "wrench light" appeared. The car would not accelerate at all. When stopped, the car rattled and idled very hard and was shaking. The service engine light came on. I turned the car off and I waited a few minutes and cranked the car back and all was fine, wrench light and service engine light was off. This has happened 6 more times since July 8th 2013, yesterday it happened 4 times in the 1 hour, almost got slammed by two 18 wheeler trucks. This really should be a recall due to this type of situation can get people killed.
