2014 4RNR SR5 Driver side mirror whistle

[sdgoodwi]

My 2014 4Runner driver side rear view mirror makes an annoying whistling sound. It's loud enough to hear with the windows closed and very loud with window down. If I pull the mirror in, the whistling stops. Is anyone else having this problem?

Same whistle

I've got the same problem with my driver side mirror. If I go faster than about 30 mph it whistles but goes away if I fold the mirror in. Has anyone figured out how to fix this issue?

I have a 2015 Limited with this same issue on the driver's side mirror. I took it in to the dealer today and they fixed it for no charge. I told them about a TSB that Toyota has out on the subject (T-SB0022-14) but I'm not sure that helped any. The cause quoted on my receipt is RG 752991 air infiltration around the driver's side mirror. The tech removed the mirror and insulated it and now the whistle is completely gone. Hope this helps some of you with this issue.
