Complaint filed regarding a personally owned 2006 Ford Expedition XLT, owned from 2/2010 to present (12/2010)> three separate instances when driving the vehicle when the "failsafe mode" warning lights and all loss of vehicle control:steering, brakes, acceleration, etc. Occurred/ randomly during this period of ownership with no apparent reason. Vehicle restarted immediately. All instances of the condition occurred when outside temperature was below freezing (winter months) into a right or left turn. No evidence of loss of antifreeze, engine overheating, coolant leaks, etc. Mechanic assessment could not find a reason for the engine fail safe activation. This is a significant, potential safety problem for the driver/passengers of 2006 Ford Expeditions experiencing the random occurring engine failure attributable to the failsafe feature of this vehicle.
