I also have minor wind noise - from the driver's side window. If I lower the window just a fraction, the noise stops. The dealer replaced the window seal and the wind noise is the same (as is my solution of lowering the window a fraction). I know the seal was replaced because I had grease all over the inside/outside of the door and the headliner! The dealer quickly took care of removing the gease (mainly I was concerned about the headliner) but I had to take the car back in because I hadn't noticed it until after I got home.
Say, I have a minor buzzing noise on occasion that sounds like it's coming from the right front part of the car, is that from the brake relay? Other than these two fairly minor issues, my 07 RX is about perfect.
Not sure where Lexus gets their workers from here in So. Calif., but I find it interesting the Japanese go to all the trouble to make (mostly..) excellent vehicles, and then the local car dealers apparently find the ones that will work the cheapest.
With respect to BMW's. I unloaded a BMW M Roadster that had a number of ridiculous problems. Ie, both power seats would slide forward and stop with a loud 'clunk' under hard braking, both power windows moaned and groaned like they had 1/2 the power they required, the clutch would also make a clunk sound when depressing at low speeds, a glove box that would rattle around and a few other quality problems. Btw, the dealer reported everything was 'within spec'....as I recall, they couldn't produce these 'specs' for me. And you don't even want to talk to my brother in-law about his 7 series Bimmer..
