Does someone have a picture that they canpost of what trim piece is coming off? This weekend I was driving my wife's 2006 RX330 on the interstate, and noticed a strange sound coming from behind me. It sounded either like the back of the car, or the rrof rack, but I could never pin point the location of the sound. To me, it sounds like something "loose" and a smacking sound, that it not constatly there, and also has nothing to do with had smooth or rough the road was. I am begining to wonder if this could be the same thing that you guys had a problem wiht here. If so, what should I check for to see what may be loose or coming off?
