I have had the same thing lately with my car as recall dated 12/20/2019. My sunroof has been leaking a little all the liner in my car is starting to fall down. It started with the sunroof and the mechanical part of the roof is deteriorating. I had to take off the panel for the sunroof because it was molding and not closing properly.
