My Prius has developed a very annoying rattle

[macmaster05]

I'm resurrecting this old thread because I have the EXACT same rattle as the OP! I'm concerned because I just bought the car used a few days ago, and it only has 10,000 miles. I tried adding a shimmy between the space made of folded cardstock paper, but there is still a slight rattle. I'll try adding another shimmy or using foam.

Still, I hate the idea of patching up my car when its only a few days old. Should I bring this in to the dealership? Is it something that falls under the warranty?

This reminds me of a ride I had in a friend's Cadillac. She was a smoker and stuffed whatever was at hand in the sunroof to stop rattles and wind whistles. Not knowing that, I once opened the sunroof and was showered with old stale stinky cigarrette butts.
