While driving a brand new (170 miles) vehicle at 35 mph on a busy city street the electric power steering suddenly stopped working. A message "power steering unavailable" popped up and the car was very difficult to steer. I had the car towed to the dealer who said it may have been caused by a glitch in the computer. This is a very dangerous situation because without the electric boost it's very hard to steer the car. If this had happened in a turn or with a driver that wasn't strong there would likely be an accident. There also didn't seem to be a clear explanation of what caused the electric steering rack to fail in such a new vehicle.
