Buzzing
when turning off the ignition there seems to be a buzzing sound coming from the rear quarter panel area, you can hear it best if you put your ear near the rear wheel well. almost like an air compressor but very quiet. any idea what this is?

I've heard it to. No idea what it is.
Another thing I've noticed when you lock your car and leave keys inside house and go back to car to try to open door handle you hear the car like it double locks itself. It's weird senses somebody's wants to open the door but not authorized to so its like it tightens up its butt cheeks like oh-oh who's out there? Try it at night when it's quiet and you'll hear car like its extra locking itself.
