Is there a known issue with the 09 Subaru Forester on the calipers rattling?

What is your question?

Recently had my Forester fully serviced at 92K miles. No problems noted however I have this annoying rattling at low speeds that stops whenever I put the brakes on. I called the dealer and they said it could have rattling calipers and it would cost over $500 to fix. Is this a true known issue and is it something any brake shop could fix for less???
