It had been driving me CRAZY!!! I practically wanted to throw the car out. Anyway, I pulled off that rear hatch door trim piece (about 13 push fasteners that you can just pry off) and then got a piece of foam and double side-taped it to the metal piece. That rattle disappeared. There are still a few minor, soft rattles that occur over bumps sometimes, but once again, I think it has to do with pieces under the rear hatch door trim pieces. One day I'll tear all 4 pieces off and insulate them.
