I know this was posted before but here goes again for clarification.
When in your IS on the freeway, roll both rear windows down at least halfway and take her up to 70 mph. There should be this weird reverberating sound within the cabin so much that it can be unbearable and it feels like your ears are going to explode. It was more noticeable in the RX we got as a loaner. I know this doesn't happen in my wife's pathfinder. Is this a Lexus thing or have any of you experienced this in other makes of cars?
