Either of two things but my bet is its this, if you have rear climate control turn off the rear fan in the back seat. Since day one whenever the fan is on there it makes a high pitched whirring electronic sound.

The other issue might be what some of us have experienced on here with the power steering pump. Try seeing if you can change the pitch of the sound by turning the wheel, if so its your pump.

My bet though is the rear fan control.
