This high pitched squeaking happens when starting to move from being parked. I've noticed it in parking lots so far. Maybe other times I have the music up so I don't hear it. Is this a pedestrian safety feature so people can hear the car coming at low speed situations or do I have brake component interference that I need to get checked out? I have the 19" sport wheels, it not throwing any parking brake codes and whatever it is it's definitely not slowing the car down.
