rattle noise in roof??
I have a 2018 Nero PHEV, which I love, but just recently am hearing odd noise from above us as if marbles are rolling around over the front passengers head whenever I make turns or stop short. I have absolutely no idea what's going on, since there are no openings in the roof, side rails, etc. I live on the East Coast, so though maybe some water seeped in and froze and are swishing around. Any thoughts?
