INTRODUCTION:
Some 2007-2009 model year LS 460/460L and 2008-2009 LS 600h vehicles may exhibit a wind noise condition from the front side window area when driving at speeds above 72 kmph (45 mph) caused by front door window glass run deformation. New window glass runs are available to improve this condition.
IMPORTANT
This TSB addresses unusual interior noise caused by deformation in the front side window glass runs, and by carefully following the instructions in this TSB, this noise 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. Vehicles, such as the LS 460, LS 460L and LS 600h, which are some of the quietest vehicles in the market today, may tend to draw attention to normal wind turbulence or rushing sounds because of the relative absence of other ambient noises.
