Anyone have any ideas? The sounds is so loud it is heard over the radio but when I push in the side area where my right foot rest on the well the rattle will stop. I have jammed hockey pucks into the small shelf on both sides and now the shelf is just popping off at the bottom. I've taken it to my dealer now 4 times and nothing, I will sell the car before driving with this rattle for another summer.
