I have been trying to ignore it, but it is eating me up everytime I drive my 5. When I go over bumps I hear a rattle coming from the windshield area. It is getting more and more frequent. The thought of going to the dealership with this one is dreadful. My wife keeps telling me to turn up the radio, but I can still hear it. This is my first brand new car and this rattle is unacceptable. My 1999 Jeep Cherokee does not have any rattles and that thing has gone on many a 4WD excursion. I baby the 5 so I just can't understand why? Any advice on this one?
