I've been a happy second owner of a 06 GS430 for a couple of months, and all of a sudden out of nowhere, the interior just seems to be way too loud for me. On the freeway at any speeds over 70mph, I keep hearing wind noise coming from the driver side front window. The door panels seems really hollow compared to my buddy's ISF. Thinking about getting some sound deadener installed in all 4 of the door panels. Have any of you guys done anything to tackle the noisy interior? Did you notice any improvements?

 

its pretty normal, there's a thread on here on how to quiet down the interior

 

This car is commonly known to be a rattle box, unfortunately. Wind noise, though? I sure didn't have that problem.

There are a handful of threads already in this forum that discuss how they're tackled. Check them out with the forum's search tool. Good luck

 

I never had a problem with wind noise, sure all your windows are fully rolled up. That would be a first don't think there are threads on that, the rattle yes, I always found it to be really quiet on the highway for me. You may want to take the door panel and take a look in there.

 

Are you sure it's a wind noise, not a wearning out tire noise?

 

This may be it too. I was puzzled by noise for the last 2-3 weeks only to discover that the yokohama run-*****s that came with the car are toast!
