I keep hearing a strange noise upon initial acceleration of every trip I make. It sounds like a pump priming or something powering up. It only does it right after starting the car. As soon as I put the car in drive and move forward a few feet I hear the sound. If I sit there and idle for any period of time, it still makes the sound. Is this normal?

turns out the strange noise was the ABS system self test.
