Open windows and whistling noise
it almost sounds like the air passes over the side pillar or seat belt mechanism and creates a loud whistling noise.
i haven't inspected any closer, but does anyone have similar issue?

I'm fairly certain that it is gap where the seat belts come out of, but the other poster seemed to suggest otherwise.
Not sure how they missed that one during testing...
