UTGS400

Okay...so I know there are a number of threads regarding wind noises on LS's. I have an intermittent ANNOYING wind noise coming from the roof. My first thought was the sun roof...I ended up adding some grease (the one recommended not he forums) and it did not help. I had my kids listen for it while sitting in the back and they pointing at the roof right below the antenna. I looked at the antenna and it definitely is a little loose...the adhesive holding in place isn't holding it.

Has anybody experienced this and if so, what was the fix? I am thinking I may use some clear silicone sealant to reattach the antenna. Thoughts? The ideal fix would be to unmount the fin, remove the double sided tape and retape it but that does not appear to be an easy job.

Is your car an LS460?

yes…it’s a 2014

I’d try taping it off first and see if it makes any difference before doing anything else.

Gerf's suggestion is good. There are google search results on this subject if it turns out to be the culprit. I agree, doing it right isn't easy, but doing it wrong can be even worse. Noises like this can be difficult to pinpoint but you have a starting point. The gasket around the sun roof shrinks and dries with age and exposure. Taping that after eliminating the fin as the source should help. It's recommended one applies a dressing to it regularly. Also, the trim/area around front and rear glass can cause wind noises, especially if the glass has been replaced without following Lexus procedures. Then there's the infamous triangle leak on the front doors. It's less of an issue on 13+ models. Keep us posted.

I confirmed the fin is causing the noise. I had a terrible wind noise/buzzing running down the highway today at about 80 mph. I saw a hardware store, pulled in and bought some painters tape and added a couple small strips on the front of the fin. The noise was gone afterwards...I even jumped up to 90 to see if it would com back. Much quieter!

So is there an easy way to remove the fin so I can re-tape it? If not, I will go the silicone route.

Great you pinpointed it. From what I read, there's a through bolt that is accessed from cabin. Probably not easy. I suggest that you research different types of sealer before using silicone. #M makes so many innovative products. Look for automotive applications. Something that is paintable would be ideal. Keep us posted and good luck.
