I know this was posted before but I cant find the thread, sorry.

Has anyone figured out what that knocking noise is that comes from the rear passenger side? It almost sound like someone is in the trunk.

clunk in the trunk. do a search here and on the other forum. some people get their rear ends replaced, others live with it, still more take it to the dealer for the dealer to say they cannot duplicate the problem.

Mine does it while sitting still- can't be the rear . I thought it was decided it was the purge solenoids for the fuel system? It certainly sounds like solenoids cycling briefly when it does it.

I hear it, too, usually within 2 min of starting cold and driving off. Used to think it was squirrells clinking beer mugs! :cheers

Agree, it sounds like some cycling solenoids, and it's definitely from the "new" fuel tank area, almost right around the fuel door.
