My car developed these rattles more than 2 weeks ago. Today I've decided to take this matter in my own hands and discovered that the rattles were generated by sunglasses holders from both doors.
I simply removed them, as I never used them anyway, and my car is rattle free again!!!

Good to know. Those holders used to make noisy on my car, too.

 

Way to diagnose that yourself!

 

(this wouldn't apply to the sunglass holder, but for other things, maybe) With all these rattles, can't we put something in the car to get rid of them? Like foam or something? lol. I don't know a ton about insulating/quieting cars - but I know with the lexus we had a rattle from the back and they said they put some sort of foam in the doorpanel to dampen the sound, and it worked.
