I've started to have this weird annoying knocking sound when I go over bumps or turning into driveways that have a small curb. It sounds almost metal like. Hard to describe and hard to pinpoint where it is coming from. It almost sounds like 2 seperate ones, one coming from passenger side door or B pillar and one coming from the passenger rear of the car. Any ideas? Thanks.

 

same here ..i havent taken the car in yet just to busy but someone has said he was told by lexus that it has something to do with the roof lining of all things..
