'10 RX350

INTRODUCTION:

Some 2010 RX350 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.

NOTE

This TSB addresses unusual interior noise that may be present in some vehicles, by carefully following the instructions in this TSB, 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 RX350, 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.
