I thought I am the only one, but I have to agree with the review written by mml on 08/10/2009. I also noticed a very annoying rattling noise from the driver side seat belt buckle area. I brought the car to the dealership but cannot duplicate it. I really hate it because the problem comes and goes. We need more people to report this problem and have this problem recalled by Lexus. It seems that RX350 is now a mass produced car and the build quality doesn't live up to the hype. A bit disappointing.
