One problem related to front suspension shock absorber has been reported for the 2005 Lexus RX330. The most recently reported issues are listed below.
Excessive bouncing and swaying. I think all Toyota cars have a potential to have faulty shocks. I had bought a new camry and always wondered why it had a lot of body roll and excessive bouncing. To make it a short story, I ended up replacing the front shocks that improved handling dramatically. Here I am, owning another new Toyota product Lexus RX 330, having a same problem. I cannot drive it any faster than 35 mph on 45 mph zone curvy country roads because the car tends to roll left and right a lot.
