Introduction

Some 2007 model year LS 460L (Long Wheelbase) customers may complain of a wind noise from the front side window area when driving at highway speeds. Use the repair procedure below to improve this condition.

It is important to note that this TSIB addresses unusual interior noises caused by slight variations in certain parts, and by carefully following the instructions in this TSIB, these noises can be improved. Your customers must be aware that some level of wind turbulence noise, especially in cross wind conditions, is present in all vehicles. A vehicle such as the LS 460L, which is one of the quietest vehicles on the market today, may tend to draw attention to normal wind turbulence or rushing sounds because of the relative absence of other ambient noises.

Applicable Vehicles

^ 2007 model year LS 460L vehicles produced BEFORE the Production Change Effective VIN shown below.
