Still no luck on my end with it. It comes and goes with the seasons. I think it's about that time again.
Mine rattles all the time. As with previous mention, pushing up on right front corner stops the rattle.
It's obvious this is a common problem. Mine does it too! I think it has to do with the temperature changing.
Have had the same issue with the sunroof but found it was the plastic casing around the interior that was shaking loose upon closer inspection. Haven't fixed it yet but glad to isolate the culprit.
