On the driver side I'm hearing wind noise when driving above 45 mph. How do I go about troubleshooting this issue? This is for a 2015 GS 350. Thank you so much!

Compare your two mirrors. I remember reading somewhere that the aerodynamics of the mirrors help quiet down the cabin.

Also do you have your wipers down? I noticed when I had my wipers up I got more wind noise. Hopefully it is something simple and not the weather stripping.

Interesting, I'll check the mirrors tonight. The weather strip on the doors seems to be fine. Yes, the wipers are down..although the right side does seems a bit higher; however, that side has no wind noise.

blue masking tape, available from home depot or any hardware store. use it to mask up the window run channels, door glass outer scratch trim, or any other spot you think you suspect the noise to be coming from. has you car been in a collision before that was fixed? sometimes body shops don't put back all the insulation or seals for a door on the inside too.

One other thing to check is if the noise is still present with the sunroof shade closed.

When the sunroof shade is open and the sunroof weatherstripping has gotten older, you might notice extra wind noise when at highway speeds.

If it turns out to the seal, you can replace the rubber weatherstrip/seal around the sunroof: https://www.clublexus.com/forums/gs-...l#post10515046

I had the same issue on my vehicle. It seems to show up on some GS.

It's the left driver side mirror, just put 2 cabinet bumpers on lower portion and it will re-flow the wind and no noise.

Around 05:18 here. I did the fix and it works.

ljCharlie

Awesome! Thank you so much for the tips. I'll definitely try the cabinet bumper.

ljCharlie

I have not tried the cabinet bumper; however, I did try folding both mirrors in when driving over 45 mph and I still hear wind noise from the driver side. So I assumed it might not be the mirror?

websurfer

Yes, I tried the same test and concluded it was the mirror when folding it prevented the noise from occurring.

My dealer had replaced the top weather stripping above and didn't fix before.

IMO, I was a bit disappointed that a vehicle so expensive had wind noise so loud. Our Camry had no wind noise. Go figure.

ljCharlie

In my case when folding the mirror and it still makes the noise.

Different issue than mines.
