Loose Upholstery

I purchased an 04 GTP roughly 5 months ago. Lately I've been hearing a lot of rattling coming from above me. I believe this is coming from either side air bag and the sunroof trim. Is this a known problem with this era Grand Prix or is it just the age of the vehicle, it only has 30000 miles.

I recently had some warranty work done on the sunroof drains and my onstar antenna, to fix a water leak, as well.

Any history on this problem with anyone?
