Wind Noise

It may be caused by a missing screw under the mirror housing. If you see a hole there, it is probably the culprit. Just put a small piece of Scotch tape over it to see if it eliminates the noise.

 

i have a 2008,and also have the same problem.. luckily this site exists and yes, thats the problem.. under the mirror you will see some screwholes with a thin plastic cover over them, some of mine are perforated and makes the wind noise at high speeds. just patch them up.

 

What!? *ugh* I didn't have such problems with my 2005 Prius... *sigh* I'm trading it in for a 2008... man - i gotta look out for some lousy screw holes?!
what is this world coming too!?

 

I get some wind noise starting around 100 kmh. I usually just turn up the stereo, but the tape sounds like such a simple fix, I'll try it.
Could it be the wind deflectors?

 

mine didnt happen until some time after also, i notice it on my trip to vegas doing 99MPH with 99MGP (on a down grade)

mine has both sides with the broken seals, absolutly no idea how they broke.

 

Mind did the same thing, coincidentally right after I had taken it through an automatic car wash. Several other posters have experienced this as well.

Did you just wash your car recently?

 

Are the screw holes indeed uncovered? If so apply clear tape.

 

We have a 2006 and 2007 Prius. The 2007 has had wind noise on the drivers side. Lately the 2006 now had whistling wind noise on the drivers side. I have felt that the window seals are the cause. Well today we took the 2006 into the dealer and they said the gasket on the driver's side mirror was worn, so they replaced it under warranty. Surprisingly, no more whistling sounds. I am not exactly sure what they did, as I can't tell by looking at the mirror on the outside of it and I wasn't there to ask them. We shall see if this gets rid of all the wind noise as well. If so I get the 2007 taken care of then.

Interestingly though, the 2006 doesn't have clear tape covering the bottom mirror screw holes, while the 2007 does.

 

Can anyone post a photo of the tape? My 2004 doesn't have anything covering the holes and I'd like to try to replicate it. Thanks in advance.

 

The tape over the bottom of the mirrors is clear cut in a circle to cover the screw hole.

 

So are there 3 pieces of tape on each mirror, one for each screw hole?

 

Yes. At least there is starting in the 2007 model year.

 

Actually, chewing gum works much better.
