JH12

We have the same car and had same problem. Brought the car back to dealer at least 5 times. They put rubber piping betwwen winshield and dashboard, removed side door panel and reinstalled for gap between door and dashboard, finally took the whole dash board out adjusted speaker cover, reinstalled the dashboard. Seems working now. it's more noisy when weather is cold. It's common problem and Lexus know about this. They are trying to improve since it's the first year of this body style..

We replaced 3 winshields since 2006
