Weird sound from FJ after hours of no use...

Very new 2014 FJ, only <400 miles so far.

So I finish my run and cool off in front of my house at 3AM and I hear this really faint buzzing sound from my FJ. Coming from around the rear axel. I stuck my head under the vehicle and confirmed multiple times to make sure I wasn't going crazy.

FJ has not been used for the last 8 hours, so I have no idea what it could have been. There's nothing in my car, so it can't be an electronic device like a phone.

So does anyone have an explanation for this sound? I don't know what component would need to be on at that time...

They all should have it and some of the '13 and up will also have the little air pump that you can hear right when you shut the engine off too.
