    Hello,

    I am a firum newbie as well as a 3 week old Prius owner. I have noticed a 5 second buzzing sound somewhere behind the dash (driver side) that sounds like electriacal sparks, at first I thought it was the engine fan turning on but then I heard that after the car was off and it is a different sournd. It happens about every 10 mins, and of course when I took it to the dealer it would do it.

    Anyway else heard this before
    Thanks
    Mike

    sit in the car with it off and press the brake pedal 4 times, hard, is that the sound? no then it's the coolant pump transfering coolant to the thermos from the ICE.
