When I run 70mph, I heard wind noise. It is not that bad and probably normal, but I'd like to know if it is truly normal. I ever get into Lexus ES330. When I close the door, it feels like I am being isolated. I barely hear any noise from outside. It was at autoshow, I get into ES330 inside, close the door and barely hear any noise in the show.

Anyone here experienced same thing? Is this normal?
When you guys drive the car at 70mph, "do you only hear road noise and 0% wind noise?" If this only happened in my car, I guess I'll have to visit the dealer.

For those of you who didn't have wind-noise at all, do you mean you guys only hear "ROAD NOISE and 0%-WIND-NOISE"? I am not sure if wind-noise is normal or not. But logically, MB won't make the car inside totally isolated with 0% wind noise. If it does, driver inside won't be able to hear horn from other cars or something which is dangerous...

Please help... love this car a lot,
cheers..

 

I don't think wind noise and horn are related.

but....

Wind noise is present no matter what car you drive. The side view mirrors really make noise and so can other parts of the car.

I know when I drive above 80mph in my aunt's S500 there is a slight whistle but right when i hit just a tad bit over 83mphish, it's gone.

 

I thought the S500 seemed pretty quiet right at 90 and up, I was really suprised. There are alot of cars that make noises at a specific speed but if you go just a little over then it goes away, such as the old old five series

 

yeah its normal- on a lot of cars the windshield over time will sink about 1mm causing wind noise

 

that must be what happened to our truck, cause now we have this really annoying sound when were on the highway, it sounds like a buzzing or humming noise, its very annoying
