Thanks for the support guys....
1. I'm not sure if this was the same FSR as I have not seen him in person. It was all done over the phone and I honestly didn't even think about that. I was told if I have any other questions to speak to SM (service manager).
2. I think it's very much possible that the last repair that was done to my car to correct this issue was not done properly or something is getting loose.
3. Comparing the wind noise, I feel that I'm back to my original problem when I first reported it.
4. Lowering the window just a bit does not change anything. It only did after the first time they tried to fix it.
5. Unfortunately, I was confused before. I have a second car that is also a lease and that one is 2 years, but this one is a 3 years lease, so I have 22 months left on it. Honestly, after what I've seen on the market, if it wasn't for this wind noise, I would seriously consider buying this car at the end of a lease. Now, I'm not sure that's going to happen.
I'm a bit puzzled at what to do next. 2 dealerships that are close to my house are both owned by the same guy. Next dealer is about 50 miles away and that is very inconvenient. But looks like I'll have to make that trip soon as this noise issue is driving me crazy. I had an ES350 as a loaner, while dealer was looking at my car, and it had less wind noise then my 460. That's just crazy!!!
The reason why I was wondering about the same FSR is that if he's the one who did the repair, he might 'take offense' at having the customer come back stating that it was no longer effective. He might also hypothesize differently on how the customer now has a different reaction than before. Perhaps some 'fresh eyes' could look at the problem without the baggage of past history. It's up to you, but if the problem is that bad, it may warrant the 50 mile drive (and perhaps 'testing' the noise level en route). Hopefully that might have some benefit?
Anyhow, am I correct in surmising that what's happened in this case involves initial success, but then a lack of permanence and reliability in the fix--it basically reverts to original (problem)? (I suspect this has to do with dealership work not being able to match the durability of a correct factory procedure). So if a following repair was effective and stayed that way, that would be a desirable solution, right?

In addition to that, the environment where the noise is measured by the dB meter must be very specific. If it's raining outside, then noise will be different, or if it's too windy ouside... and all of this makes it very difficult to prove either way.
There was a magazine test which still included some dB measurements, name escapes me at the moment. However, perhaps more useful, the actual dB measurements from the LS 460 designers themselves, included in the press information from Lexus GB:

were you thinking of Edmunds maybe?
These are for the 07 LS460 and what would be interesting would be to see the dB change for 08 with the addition of laminated glass for 08 compared to values for 07 without it as below.

I just called the dealer back and ask them to find out form FSR how he has determined if the wind noise is at acceptable level and also to find out if the dB meter was used and what were the numbers. I will post it here once I get that info. I also just called Lexus Corporate and filed a complaint.
If I remember right there are at least 5 each side of car and they are all black in color. If LS has underside (plastic) cover preventing seeing, you may have to ask dealer to confirm some of the plugs rather than able to see for yourself.
Here is a better conveyance I think as pics are easier than trying to write detailed descriptions.
Go to post #23 and you will see pic of two smaller plugs, plug holes missing plugs, that are near front wheel well arc approaching/meeting underside of cabin body on both driver and passenger side of vehicle. If either of those is missing on either side or both are on each side, or pushed too far in allowing air in, then ...... noise like you would not want. The first pic shows the round plug missing and the second shows the oval one missing. After his dealer put them in, much improved, but he learned about it right here on CL thanks to member input in problem solving then he went to dealer to have it corrected. The perspective is off in pics, they are about the size of a quarter or slightly larger maybe at most. If they forgot to do this, seems they arrive with them in the glove box, possibly in trunk, but for sure have seen mention of glove box, for PDI folks to install them, so if you see any in glove box then there may be some missing.
I am one of the owners of a 460 LWB that had the TSB done for the wind noise. When I got the car back, the wind noise was worse than ever on the driver's side now even starting at speeds above 40 mph. Before the noise was annoying above 60 mph.
A friend of mine who is an Aeronautical Engineer at Gulfstream drove the car and after inspecting the window area found that the small triangular black piece covering the bottom front of the window was extending outward from the glass leaving a small area where rushing air could penetrate.
I sealed this black strip with painters tape (see photo) and took the car out for a short test drive. I got the car up to 80 mph briefly and my initial impression is the wind noise problem is gone. I want to take it out hopefully later today when there is some wind and drive it for a more extended period.
It now makes me wonder if the TSB was successful in the first place, but they created a new problem when putting the door back together. I say this because, the passenger's side seemed much improved after the TSB. The black triangular piece on that side is much more flush with the window.
great work there! it's great to see some owners taking the time and effort of their own to try to find out the cause of the noise! good luck, keep us posted

Not sure this makes sense, don't many people report that if they lower the window just a tad, the wind noise goes away or is less noticeable?
I have read the thread, that's why the black triangular piece doesn't make sense to me regarding the wind noise. Doesn't seem that the triangle would be affected by lowering the window just a tad, which seems to help.

The black triangular piece that I refer to in my post has nothing to do with lowering or raising the window issue to correct the wind noise. The increased wind noise I experienced after the TSB was caused from the this black triangular piece not being flush with the driver's side window. As mentioned, there are multiple issues at hand here concerning wind noise that is being experienced by various owners.
I drove my car again last evening with the tape covering the black triangular piece. Although, it was a short trip, the wind noise that started at 40 mph was entirely gone. I still want to take it out on a freeway preferably on a windy day to make a final evaluation, but I am becoming more certain that the TSB was in fact successful in my case. The problem was that the black piece was not properly reinstalled.
It may be wise for owners who have had a non successful TSB done, to check the black piece for a flush mount to see if this is a problem.
I think the thread points out that there may be MULTIPLE causes of the wind noise that owners are complaining about.
EXACTLY. i have read so many different possible causes, so many different possible fixes

Yes it helps, but in my case anyway this "temporary" remedy went away when my windows were replaced with the laminated glass as well as a few other modifications that are part of the TSB. I speculated that the noise reduction that resulted by a slight lowering of the window was caused by a decreased force being applied during the upward motion. Prior to the fix, the door frame also seemed to move as though it was being strained by being jammed by the window's motor. After the fix, everything operated smoothly, and of course there was no longer any effect by slightly lowering the window. Perhaps the repair guy spotted this anomaly and adjusted the travel. If this phenomena still exists after a window replacement, it may be a symptom that the travel has not been adjusted imho.
Sorry to spend so much time on unplugged holes in the bottom of the car, but I'm now curious ... There are a couple of holes on both sides of the underbody plastic shrouding of my car that aren't plugged. They are about 12" in from the edge of the car body, and about 6" and 18", respectively, from the trailing edge of the front wheel opening.
This pic shows both holes. Sorry for the quality, but it's hard to wedge a camera in under there. -
