Three times over the past 6 months I have gone back into the garage hours after parking the car (in one case the next day) and hear a buzzing sound coming from somewhere under the floor in the car- I can hear it the loudest if I listen below the car on the middle/right side. In each case if I turn the key to on/off the sound stops.

It definitely seems like something electrical that is running- which is disturbing.. I feel lucky to have caught it each time..

Has this happened to anyone else, or any ideas what this might be?
