Whenever I closed the doors with the window up, the window occaionally get trapped outside the rubber seal creating wind noise. When I lower the window and closed it again with the door shut, the window will then be under the rubber seal at its proper positon.

I took my car to the dealer and they said that it's the characteristic of the car and there is nothing they can do about it. I'm just wondering if it's true or I just got duped. Thank you.
