noisy interior

It hard to tell with such limited description. But I'm sure you could be right if your previous car is a Lexus LS430.

Get someone who is used to these cars to drive it. Way to limited to know by a web posting if it's normal or not!

Actually, I think it is the sunroof that is causing the problem. As soon as I opened the slider, the noise level went up dramatically.

Need to get it sealed, I guess.

Wind or tire noise, I wonder?

If the tires have some miles on them, they may be noisy even with lots of tread left. Noise over the long-term is not a consideration when designing most tires now, and they can start this relatively early. Maybe 1/2 to 2/3 of the tread left. And they just get worse after that.

You can rotate them if they're making a wha-wha noise, but if it is a constant roar, they're shot and you'll have to replace them if you want it quiet.

EXACTLY - I experienced a similar problem. I find the noise to be higher when on the freeway. Then whenever I open the slider, it makes real big noise. It seems that the rubber seal (or what ever they call it) must have come off or must be loose. In my car, now I can actually see the rubber edge come off. Try going to the car wsah with your slider - it might leak some water too.

You get a rubber sealant glue for rubber trims, etc from Kragen or autozone. Try fixing that and other rubber edges like on the door etc.

I had bought glue, but haven't had a chance to fix my car so cant give you

Let us know if it works for you.
