I used to have a 06 xa and traded it in for the 08 xb, love it... But I'm posting because with both cars I noticed that when the two front windows are up and the back to are down, the car vibrates and its sometimes painful to the ears. My new xb does it also and even more then the xa. Has anyone else noticed it? It usually occures at about 50+ miles per hour. Is this normal? I have never come across it in any other car that I owned.

this was posted before and it's normal, it's air pressure that is causing it, if you crack your front window it should go away. Had this happen on numerous vehicles before, some worse than others. but yes, it is normal

Yes, there was a previous post not too long ago. I also agree that most vehicles do it, especially (in my experience) the ones with more vertical back windows. My last vehicle, a 2006 Chevrolet crew cab, did the same thing.

it is because a lot of air is coming in and with the rear widows up there is nowhere for the air to espace. The overfills with air and the same air becomes trapped inside causing a lot of noise and rumbling
