Even after the first day that I took delivery of my Mazda 6, the driver side door has had this anoying rattling sound, 4700 kilometers later, the driver side door rattling sound has increased dramatically as well as rattling from the passenger side door and both rear doors, headliners on both sides and these past 2 days, I've noticed a new rattling sound coming from the dash. Now, I know Mazda fixes this crap under warranty, but it will come back just as it di with the Mazda 3. I can hear rattles in my sleep after a one hour drive in the car. How should I proceed after having Mazda take a look at the vehicle and if the sounds come back which for sure they will. And for how many hours minimum do they have to keep my car so that I get a courtesy car?
