Anybody else experiencing this? When ever I am traveling at speeds greater than 30-40 mph and I hit a slight bump in the road, I get a rattle/vibration coming from the area around the front sunroof. I have tried to pinpoint, but can't quite find it. It is not the screen or the latch and if I close the screen and keep pressure down on the latching mechanism, it still does it. I have put my hand in the little opening where the screen clicks in and if I keep my hand there with pressure the rattle stops, but I can't figure out exactly what pieces are vibrating. Of course, now that I am tuned in to it, I hear it all the time. Does anyone else have this and have you figured out how to fix it?
