I've been reading the various posts about RX330 dashboard noises. My RX is one year old and has been to Pohanka Lexus, Chantilly, VA three times. The dash has been removed and the TSB was performed. No luck at all. It's been in the shop several days now - I don't think they have a handle on this. This has not been good first Lexus experience. I also had to deal with a factory defective windshield - improper laminate bonding I was told. For six months it had a constant haze - very hard to see at night.
