It sounds like a tinny, higher pitched creak, not so much a vibration. Every little bump, side-ways motion, even louder than normal farts set the creaking off, and i can't take it anymore.

So I hired my roomate to ride in the rear to narrow down the cause, and I believe I've found the answer: the rear seat, namely the 2/3rd's side, is rubbing against the rear deck lid, causing the noise. I folded down the seats, and the sound isn't there. The smaller side in place, no sound. The bigger side: BAM! Annoying-as-**** creak returns.

Now that I know the cause, time to figure out a solution. Could take it to the dealer, but I'm not going to take off work for this bull**** until all options are exhausted.
Do you have leather? I do and I get this same problem. The dealership can't do anything (as far as I know).

Here is my fix:

(might not be the right measurements, just for reference)

Lay that between the back of the seat and the rear shelf, close the seats. That will put a nice cushioned barrier between and gets rid of the sound. Also, the dark gray color looks stock.
