    I have been driving a Prius since 2005 and know that occasionally a motor or pump will run after you turn off the car however on two occasions now I have went into the garage hours after my new Prius Prime Advanced with 700 miles has been turned off and I hear what sounds like a motor or pump running and it seems to be coming from the left rear of the car. Once it ran for at least five minutes so I started the car, waited for the Ready light and turned it off and the motor had stopped, Today I went into the garage about five hours after the car had been turned off and I heard the sound coming from the left rear. It stopped on its own after about 5 min but I don't know how long it was running before I heard it. Is this normal?? I did not take it to the dealer as it will only do it occasionally, Is there a fuel pump in that area?

    Most recent Toyota’s do this. Purging the charcoal canister. Usually about 6? Hours after shutting down.

    Is it making the noise while you have it plugged in charging?
