I'm agree with you a 100%. I had the same problem since the day I got my car and is really annoying, it go over your music and phone calls.
My friends noticing to, when they ride with me. you do not expect something like that to happen in a luxury car. I took my car to the dealer for the nine time already in one year, because of the rattle noise. the last thing I got told was that the chemical used for the window tint cause that rattle to happened and they cant not fix it because I lost the factory guarantee.
