I have a '03 IS300. It's currently at 60k. I bought the car new @ $34,000. I travel a lot and on the highways, I like to go .. fast. :) After about 15k miles, there was this whistling noise, now if I'm going more than 90miles, sometimes even 80, sometimes has that noise too. I took it to the shop when I first noticed it and they wouldn't test drive it cause they refuse to go that fast, which is understandable. All they told me was that it could be an air hole somewhere that is making that noise when I'm going that fast. I don't know if what they're saying is true or if there is really something else going on with my car. I'm worried that it could be more to it than just an air hole, and for the price I paid, there shouldn't be any air holes! Does anyone know what it could be? I'd really appreciate it. Thanks!
