Default Pump Running?

The last two mornings I have gone into my garage and have heard a faint "buzzing" noise that seems to be coming from the rear of my wife's 2013 RX350. Given the location of the noise, my first inclination was that it was possibly the fuel pump running a cycle for some reason. But when I heard it for the second day in a row, I figured it would be wise to ask if this is normal or something I should take up with the dealer?

Thanks

Normal, some fuel vapor evacuation thing that activates up to a few hours after shut down. There have been a few threads asking about the noise.

Thanks for the info. Would it be odd that this would be happening at 5/6am when the car has been off and parked for the better part of 10-12 hours?
