Many times with in the last few months my Ford 2012 feista will just turn off while driving, it does not matter if its hot or cold, flat driving or mountain driving. The car really does not perform well in traffic situations,and the failure occurs more during stop and go type of driving. When this happens the engine malfunction light will turn on. At that time you have to turn the ignition switch off and restart the car, sometimes the signal will turn off, sometimes it does not. This failure has happened in the middle of intersections, on the freeway or just driving through town. The car will shutter sometimes before it shuts off, or just starts to stall. When this happens I am able to move to the shoulder or pull off the road to restart the car. This failure of the car just stopping while running while has a high potential of me being in an auto accident. Since this failure happens at any time and cannot be predicted I take my life and my families lives in danger every time we get into this car. I can only take guesses at what the problem is, it could be the fuel injection, transmission, or some type of engine misfire. I have had nothing but problems with car since we bought it. I have read many complaints of this type of failure for this vehicle when reading reviews. It is my hope this issue can become a recall or that Ford will take action.
