My RX 330 has been in the dealership repair department for four days now. At least they gave us a loaner car. They do not know what is causing the rear end clunking noise but are trying to figure it out and admit that it is unacceptable. They did a software upgrade for transmission shifting smoothness and tried to convince me that I need to drive it for a while so that is can learn my driving habits and then it will shift smoothly for my driving habits and style. I got a good laugh out of that one - what about multiple drivers in the same family - how will it know who is driving? I am going to investigate the automobile lemon laws in RI. Rented a Chevrolet Malibu on a business trip yesterday and the trasmission shifting was smooth as glass. Shame on Lexus, their high price, and inferior quality!

My RX 330 with 3,000 miles and auto transmission AWD makes a clunking noise slowing down at about 20-30 MPH. It sounds like it is coming from the rear end. What is it? Also, I am not happy with the transmission smoothness at all.
