My 6mth aveo gives off a rattling sound even when the road is only slightly uneven. And when there is a hump,there will be a creeking sound!!! Some1 gt any advice??

Why don't you just take it back to the dealership. You said it's only 6 months old so I assume your still under the 3yr/36,000 mile warrenty.

I know it's been a while since you posted this, but I'm curious if you ever found out anything.
I just bought a 2005 Aveo LS and noticed the creaking sound when I go over big bumps or uneven surfaces.
Especially when steering to the right. Weird!
