So my 2009 LS460L is approaching 16 years of age and not sure if its due to age or something else but it sounds like a mini hurricane inside my car at speeds above 70mph especially when there are crosswinds on the highway despite having lamisafe windows.After researching a bit on the subject came across the famous jmcraney fix and planning to go ahead with it at least on the driver side initially. That said has anyone found any other possible cause of wind noise apart from the fix especially on their ageing LS460s? Would like to fix it all in one go if possible than multiple attempts. Its extremely annoying when my neighbours 10 year old corolla sounds quieter inside the cabin than my LS.

Yes, it's also the shape of the mirrors that creates turbulence between the space between the mirror and window. I noticed this when I was driving in torrential rain. Fortunately different mirrors will fit the LS460, but at a cost.
Although some have messed with the mirrors no one has reported a significant improvement there. For the vast majority of those experiencing wind noise problem it was related to the trim defect on the front doors. The LS460s and LS600s are exceptionally quiet when the trim is repaired.
Yeah, I had the problem and did the fix. It helped a lot, but there was still wind noise and I couldn't see what was causing it until I saw how the rain was being blown over the mirrors. Think smoke in a wind tunnel.
Respectfully, I have to disagree. I followed your instructions to the T, and while it made a huge difference with wind noise, I still had some noise under certain conditions such as crosswind as reported by the OP.
You can't possibly make a claim like " If you do a “good job” on the trim repair there is no noise, rain or shine " if you haven't tested the fix under every possible scenario.
Of course I can’t see what is wrong with your car, but I assure you that there is nothing wrong with the mirrors. Lexus has sold a lot of these cars and they are regarded to be one of the quietest cars on the road.

Thanks for your input. I have gone ahead with your solution but it hasn't completely resolved the issue particularly in crosswinds. What could be the issue?

In 2009 Lexus had a noise reduction procedure for the LS460 that involved adding foam to the mirror mounts and belt line moldings. I performed that procedure on several cars as per my supervisor's instructions. No improvement, ultimately each car needed new front door glass run weatherstrips. Perhaps the short life of the weatherstrips was due to our hot environment, the glass runs had poor tension on the front door glass and leaked air at speeds as low as 45 mph.
Using a stethoscope, listen for air leaks above each door glass.

The glass run in # 5 in the diagram.
Thats a great idea. Were the customers noise complaints resolved with the replaced glass runs? Also dont stethoscope pick up vibrations, is it able pick up small air leaks in the windows?
