One problem related to windshield wiper/washer has been reported for the 2004 Lexus RX330. The most recently reported issues are listed below.
This car is equipped with an automatic wiper system. When the automatic mode is used the wipers fail to keep the windshield clear. In a light rain, the windshield can get to the point where you must take manual action to clear the windshield. I understand that this problem is not isolated to my car but occurs in other cars equipped with the automatic wiper system manufactured by Toyota. I've reported the problem to Lexus hq.
