Well, I've had my Highlander since 2001 and it's squealed in very high winds off the windshield corners. But it's not really that big of thing. When it happens, it's on a REALLY STRONG gust. The whole car is shoved and it howls! Also funny, of course is the incredibly pounding helicopter sound that happens with the Sun roof open and a rear window....even just one window open you can get a pretty good thundering going in the car. Pretty funny actually. I love to torture the kids with it if they're bad :D It's just how it is. Next year they reimagine the whole car, so hopefully they learned about wind since then ;)
I think overall the car has been very quiet....assuming it's not windy out and the windows are rolled up.
