LS460 Wind Noise Fix (merged threads)
#616
Lexus Test Driver
PDI rubber plugs: If any one is missing or upside down or not properly set of roughly 5 or 6 each side of vehicle there WILL be more wind noise and more road noise present, as to road noise the most noticeable would be tire on pavement noise or hearing passing vehicles more than one would think should be able when any one or more are left off vehicle, or as above, at PDI.
Same on the LS?

Apologies if this has been covered before, but can you give the number and location of these plugs? I recall one of my other cars had 4 of them, one each behind the front wheels and one each in front of the rear wheels, all on the underside of the "frame".

I know there should be two of them right near where front wheel well arc meets flat underside of car, take a few moments to really look in general area and you should see them and from memory no further away from back edge of tire than about 8 inches or so. Those are smaller ones and very close to each other, as within inches of each other, one is round shaped and the other oval shaped.
Then there are two more, larger ones about the size of a silver dollar, round, more or less right in front of where you'd guess front of seat edge for driver is on underside of car and also similar for where you'd guess rear passenger front seat edge might be on underside of car.
I am less sure of my recollection of this potential last one, but seems there is one more smaller one near rear wheel about a foot or so from one you find under passenger seat edge, if you look for a while for this last one and don't see, then blame my bad memory...LOL.
In all of the above they should be more or less within a foot of edge of car, no further in than that on underside of car than.
Side note: Road noise or tire on road noise is also increased if they forgot to spray on/coat the underside of the cabin of car with that sound deadening rust prevention black goop that is paintable to match car color under there which also you will see surrounds the two larger plugs, my first one they had forgotten to apply that stuff, 2nd one had applied it and less noise.
Hope the above helps.

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!!!

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?
I would love to, but how would I prove that the wind noise is louder then it should be if Lexus says it's at the acceptable level... There is no measuring stick. They could use a DECIBEL (dB) METER to measure the noise, but I haven't seen the numbers for the acceptable levels yet. If anybody has those, I would appreciate it if you share that info with us. 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.

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.

Db @ Idle: 37.2
Db @ Full Throttle: 68.3

were you thinking of Edmunds maybe?

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.

You are more than welcome.
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.

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.

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.
