I've owned my 2007 GS 350 for 18 months and have enjoyed it except for 2 flaws. The rattling dash board and the squeeky/squeely brakes that are so annoying. I had the dashboard taked care of by Lexus America. Fortunately they acknowledged the problema and got it fixed for me. The brake problem was only recently resolved when I decided to try ceramic brakes for the the front where the loud obnoxious sound was coming from. It truly was very embarassing driving this fine car that sounds like a diesel truck with bad brakes. Anyway, I went to autozone and purchased the top of the line ceramics for this vehicle. It cost me $50. Then I went to a brake shop who agreed to install after re-surfacing the rotors. Cost for that was $100. Voala!!!!! I could not believe the problem was resolved. Not a single sound when I come to a stop. I am amazed that Lexus does not recommend this solution. I guess it's because it's not a lexus part! I am very happy with the outcome. :)
