    I have a question. What in the world is the buzzing I keep hearing that is inside my dash on the driver side? It only last around 2-3 seconds then just stops. This can happen every 10 minutes or so. The car drives fine and I have no dash warning lights. I assume it is normal, but I'm just wondering, what the heck can it be. It's an 07 base model w/ pack 1, with only 1200 miles on it...

    Any info would be greatly appreciated, thanks!!!

    It's the brake accumulator pump. The Prius engine isn't always on, so it uses an electric pump for the power assist on the brakes. You should hear it about every third time you press the brake pedal (roughly). It's completely normal.
