Ok I've found rattles that are similar to some that have been talked about, but nothing exact.

I have a rear rattle coming from the roof. It is right near the hatch, and it is actually behind the little box over the rear seats. I do not have a sunroof, and there is something loose in the roofing area. The rattle isnt actually from the box, its like about an inch or two down from it. Right in the middle of the box and the hatch.

I've knocked on it with my hand and it produces the same rattling sound when I drive and hit bumps in the road. I don't know how to fix it since its not anything that sticks out or a compartment or anything. It is flushed with everything else.

Help me out guys
