Spoke to my service manager today about the sunroof. They tightened some screws which did help. I pointed out the movement of the panel, in the closed position, as it is not as 'snug' as before. He told me that he would replace the glass panel with a new one that is thicker, thus making it heavier to kept it in place. It seems that others are complaining and this is the fix. I'm awaiting for the glass to arrive and be installed under warranty!!
