Common cause: Caps covering the child seat anchors. Opening/closing the caps typically fixes for a while.

Rattle: Armrest rattle that goes away with pressure
Common cause: plastic on plastic contact around armrest hinge. Fix with felt tabs.

Rattle: Constant rattle around steering wheel
Common cause: Cruise control stalk. New stalk may be required.

Rattle: Harsh rattle from passenger's side when going over bumps
Common cause: ???
