Summary: the wind noise issue has been defined in the TSIBs as "a high-pitched whistle-type wind noise" from the front side windows or the base of the outside rear view mirrors, which may occur while driving at highway speeds. The issue is distinct from normal turbulence and background noise, in that it sounds like the door or a window is not fully closed.
Prevalence: based on the reports on this board, the issue is most prevalent among owners of 2007 LS 460s. Members have debated the issue because some LS 460 owners have reported the issue, while others have not.
Fix efficacy: owners on this board have reported differing results with the implementation of wind noise fix(es), ranging from ineffective to successful.

*The wind noise fix applied in NV009-07 is available for LS 460s whose VIN# last eight digits are below 75039579 and LS 460 Ls whose VIN# last eight digits are below 75016531. Those 460/460Ls with VIN# higher than that already feature factory-implemented production fixes.

The 2008 LS 460 and LS 460 Ls come factory-equipped with laminated (Lamisafe) front side glass.* Part of the wind noise fix for the 2007 LS 460 includes the addition of laminated (Lamisafe) glass to the front windows, replacing original tempered (Temperlite) glass. The 2007 LS 460s came with tempered glass only, while the 2007 LS 460 Ls featured laminated glass. Per 2008 specifications, all LS models have laminated glass. (*excepting some very early 2008 models).
