While driving with a small child in the car - less than 15mph near a residential area - my 2005 Ford Expedition ltd suddenly flashed an error message "check electronic throttle control" and immediately lost acceleration, braking and steering. I was able to veer the vehicle to the side of the road without causing an accident. I used the emergency brake to stop the vehicle at which time I manually turned off the ignition. Waited a few moments, and managed to get the vehicle started and running again. There was absolutely no warning and the vehicle gives you no opportunity to get the vehicle pulled over safely before disengaging. This appears to be a very serious and dangerous sudden mechanical failure.
