I visited this thread because there seemed to be a intermittent rattle on the right front and right side of the car. It was really noticeable one morning on a rough section of road and seemed to be coming from the passenger door. Now, I had a bunch of stuff in the console drink holder (chapstick, pen, alarm remote, and other loose stuff), I reached my hand in to see if the rattle was coming from there. Sure enough, the rattle stopped. To confirm that was the problem I placed a soft cloth in the holder, lining the drink holder, and the rattles stopped.
It seems that a rattle caused by stuff in the drink holder does an acoustic trick and sounds like the rattle is coming from the right side of the car. Check for loose stuff in the various plastic storage areas for loose stuff, pad it with a soft cloth or remove it to see if that stops your rattles.
