I just accidently found out this morning when I got to work, turn the car off, open door but I forgot something in the car so I stay and close the door because it cold and about 1-2 minute later I heard this noise in the front seat area for 2-3 seconds, the noise sounds just like the steering wheel tilt motor makes when you put the key in the ignition but much lower sound.

I thought I was hearing things so I turn the car back on and then turn it back off, open the door and then close the door with the key still in the ignition and samething 1-2 min later I hear the same sound again but don't know what it is..

Any idea guys ???

It's not the memory seat moving is it?

I can't see anything moving at all, I am sitting on the driver seat. Just hear the sound like a seat motor or steering wheel tilt motor running but don't see anything move.
