 I baught my 2013 rav 4 and everything was fine until I decided to open the back windows, while going down the highway. the noise hurt my ears. and I mean really hurt.I contacted the dealer. and he told me he new about the problem. and suggested that I shouldn't open my windows ???I then contacted Toyota and explained the problem to them. they told me to go on a ride with the service manager, to show me that they all have that problem. But offered no remedy. I guess if that's the case! the windows aren't meant to be opened while driving!!!
