yes, i've just noticed this - put the car in reverse and a fine vibration from the transmission plus a noise more prominent than the idle sound - there is total silence in drive,park and neutral - maybe it's normal ???? please check it on your cars,too. thx.
this happens while the car is in reverse and the brake pedal applied, the car is not moving
