Near the sunroof opening, there is a plasticky rattling/ticking sound that happens over uneven pavement. It seems to come and go depending on either temperature or how long I have been driving, I can't tell which. I've tried lubricating the rubber seal around the sunroof, but that didn't help. I believe the noise is actually inside the car, either in the headliner or something in the sunroof mechanism itself. I've tried everything I can on my own. Overall it's not the worst, as playing some loud music is enough to make me forget about it, but it's definitely annoying.
