Passenger side NPP valve rattles when closed
It's tinny, high-pitched vibrating sound when closed at idle. Who knows if it's there when I'm driving. Brought it to the dealer and after 20 mins of BS from the SM, he agreed to pull up another one from the sales lot and agreed that I do have a rattle. We'll revisit on my next oil change in the next couple months.

There is a bulletin to seal the rivet for the valve. If that doesn't work, they are supposed to replace the muffler/exhaust

 Lots of threads on the NPP rattle. There is a fix, they will Glue your exhaust. Pretty awesome right? Your dealer should have known about it, it is not a new issue.
