I was driving along with windows up, radio off (rarity), and A/C on low to see if I could hear any rattles so I could bring them up during my next oil change. I finally heard one. I thought it was coming from the glove box. I started applying pressure to various dash panels until I realized it was from above. I thought it was the moonroof. I finally found the rattle coming from my glass lens Ray Bans in the sunglass holder.

2 TLs, 19000 combined miles, and still rattle free!! Good job Acura!
