06 Sonata - Rear Clunking Noise
 

This is driving me crazy. After hitting smaller bumps going no more than 40
mph I hear what appears to be a recurring clunking/rattling noise almost as
if the rear suspension isn't absorbing the impact (it is though). It's a
definite rattle and related to hitting the bump. It's most pronounced in
the passenger rear as I had a friend drive me around while I was in the
trunk. I've heard some talk briefly about this, but no fixes have been
offered or suggested. It's been to the dealer to no avail and I've even
driven the same vehicle and the noise is present in that too. It's a GLS
with V6 and 17" tires. Anyone else experiencing this too?
