I just started hearing a noise/squeak coming from the headliner/roof area of my MY15 "R" Coupe. Anyone have a similar problem? Any ideas? It has the pano roof.

 

It's not your roof. It's the back parcel shelf. I had the exact same problem. The back shelf has been redesigned but is on back order. Also check the plastic assembly where the hinge points are for the parcel shelf. Mine was very loose on the right side.

Try this: take a T shirt or a towel and jam it between the parcel shelf and the plastic side of the hatch area right behind the hinge point....close the hatch so that the T-shirt is jammed tight. You should have no noise until you get it fixed.
