Was this ever fixed? I am experiancing the same problem but the incompetent technicians of McGrath Lexus in Westmont IL say that it is normal air noise. My problem just started to happen 1 month ago, I have an 02 IS300. The high pitch wistle happens as soon as I hit 60 MPH, and can be reproduced everytime. It is a whilstling noise that seems to be coming from the drivers side front window. I have had nothing but problems with this car, whether it is the panel under the steering wheel rattling like I am taking off on a 747, or both the passenger and driver side font seats squeeking like 30 year old couches, and now this whistling noise. The think that bugs me the most is that the STEALERSHIP is like an insurance company they will keep denying your claim until one day they may take a look at it. I would expect more for a $36,000, but hey I learned my lesson.
