Lately I've been hearing an electric motor/grinding sound from under the hood when the engine is cold as I begin to drive away. It only lasts for a few seconds, a minute at the most. Sounds like its coming from the left side of the engine compartment. The engine doesn't run in any abnormal way and no indicator or warning lights come on when I hear it. Then it just shuts off and the electric motor sound just turns off and the sound gradually fades away.
I have no clue what this might be. Anyone have any ideas?
