I own a v6 2010 Ford Fusion and on two separate occassions, while driving on the highway at approximate speeds of 65 mph the engine has stalled without warming. At the time the engine stalls, a service light will come on and the car completely shuts down. In both instances, the car could be restarted, and the service light dissapeared upon restart. We have taken it to the dealership after both incidents, and they are unable to identify a fix as the service code is not being stored in events of engine failure (and the light is not staying on after restart). This is an extremely dangerous situation as it has happened without warning, while travelling on major highways at high speeds. I have seen entries from other owners on both the nhsta site and other blogs siting the same problem, yet Ford is unwilling to accept that this is a pervasive problem and is not working to find a solution. We have escalated from the dealership up to the corporate Ford customer service department with no success.
