One problem related to paint has been reported for the 2004 Lexus RX330. The most recently reported issues are listed below.
My 2004 Lexus Rx330 has horrible paint issues on the front bumper. Paint started chipping off in huge sections and it looks terrible. This has only happened on the front bumper and the rear view mirrors. Seems like the paint is defective in these area's. So disappointed. Also the transmission is messed up. Seems like it hops in between 1-2 rpm. I even had the transmission rebuilt and it still didn't fix the issue. It still does it. I have heard that this is a major issue with these vehicles.
