Yup, mine creaks from the back shelf area too when its cold out (until the interior warms up a bit). It sounds almost like the metal buckle of the seat belt tapping up against the glass. Fortunantly, I haven't noticed it as much lately since it's getting warmer.
If there's an official TSB though, I'll consider taking it in. I don't want them ripping apart unnecessary parts of the car.
