    Went out to garage after parking vehicle 8 hours ago. I parked it unlocked with driver and front passenger window open, also back tail window open.

    I go into garage hear a buzzing noise. Coming from rear around driver rear tire. then you can here it change tone.

    It sounds like a fuel pump, I dunno

    I did have key fob with me but didn’t touch the vehicle. I just heard it when I entered the garage.

    It lasted until I started vehicle.

    Went for a drive, parked it in garage

    Fuel tank evap pump testing the vacuum system. It does it automatically after the car has been parked for awhile.

    Totally normal.

    I remember the first time I heard it, I thought the fuel pump was running even though the car was turned off.

    Yep, a year ago, 2AM could not sleep, walked outside and heard "that" noise. Took a min to locate it and thought how weird. Bug? car running itself now? Skynet?
    Used the net to find all threads discussing...Ok! normal operations. Yet, I still keep my eyes on the 4runner just in case it tries anything 'Arnold-like'. Personally, I figure it will be the garbage trucks with robotic arms that kicks things off.
