Production Change Information has been updated.

Introduction
Some 2010 RX 350 vehicles may exhibit a wind turbulence noise condition noticeable from the front side window area. This condition is most notable at highway speeds. New acoustic glass is available to improve this condition.
This TSIB addresses unusual interior noise that may be present in some vehicles, by carefully following the instructions in this TSIB, noise levels may be improved. Customers should be made aware that some level of wind turbulence noise, especially in cross wind conditions, is present in all vehicles. A vehicle, such as the RX 350, which is one of the quietest vehicles in its segment today, may tend to draw attention to normal wind turbulence or rushing sounds because of the relative absence of other ambient noises.
