general problems of the 2007 Toyota Prius

Car suddenly stopped while driving and all electical functions ceased. Occurred one time only in 10/09. Car was towed to dealer and was told there was a pebble in the throttle. Car had been driven only on city streets,no country roads or off road. Throttle was cleaned for a cost of $350. .

The mileage is between 30 and 35 mpg, which is a long ways from the sticker claim. The headlight goes on and off intermittently, even though replaced several times. Second headlight is also failing. The blower works only intermittently, usually after hitting a large bump in the road.
