Vibration noise coming from passenger mirror?

2016 SR5 4x4, at freeway speeds I'm getting a strange, intermittent, whistling/vibration sound that appears to be coming from the passenger mirror area. Haven't been able to pinpoint where exactly. Anyone else experiencing this?

 

That sucks bro, I am sure others will have the same issue. This is what happens when Toyota rushes out with a new vehicle to keep up with the competition. Not that the others are competition, but I am looking at all the posts with this problem, that problem. Sad just sad that for that kind of money these issues are arising. I have never been on a Lexus forum or know anybody with a Lexus, but I hear you have to sit through a presentation of how well the Lexus is built. Why can't Toyota put the same love and compassion into now an almost 40,000 truck. And I would like to say that all these little issues will be worked out, but they probably won't be. 10 years now and they are still having some of the same issues as when the 2005 Second Generation came out. Long winded response but the truth all the same. Somebody I am sure will chime in with a fix, or remedy at some point, good luck

 

Does it sound like this? 35-45MPH Howl.

If so take it to your dealer and confirm they hear it. I have had to get Toyota Motor Sales, U.S.A., Inc involved as my dealers has not entered a record of two visits I had with them for some reason.

 

To be honest, I didn't really hear anything on your recording other than normal road noise. Mine is like a high pitched vibration/whistling sound. Did you record that using your phone or a digital recorder? I might try to replicate my sound using my phone and post it.

 

Just a phone...... there is metallic howling noise in the file.

 

10-4, I listened a couple of times, but still not hearing it, must be due to never wearing earplugs when I should have on the range? Every time I've heard mine, it's been at 70+ MPH and I swear it's coming from my passenger mirror, almost like the plastic mirror housing is vibrating and making the high pitched sound.
