Back windows down
So we have had our CT about two weeks. My wife drives it during the week and I drive when we're in the car together. I had a few too many Sangrias at the family Xmas get together so my wife drove us to our in laws afterwards. She rolled down the back two windows for the dog and immediately a loud painful reverberation vibrated through the car so loud I started to think it was that front vibration some people on the forum have mentioned happens at 20 and at 70 mph on some cars. Then we realized this happens on some cars when the windows trap the air coming in. I don't know exactly what or how it happens I just know you have to crack a front window or the sunroof to make it stop. You can always roll the back windows up instead. Anyway, just glad it was not something serious. Does anyone know if this is a design flaw or if it happens on all cars. Seems to me it didn't happen on the Element but then again the back windows are different?

It has to do with aerodynamics.
Most (or really all) cars today are designed to be operated with the windows up. MPG, sound deadening, stability, etc... all designed with the idea that the vehicle is a solid item traveling through the air.
As pointed out, all cars do this to a degree. Some worse than others.

Exactly, The Honda Fit is really bad too if you have the back windows down.

I have the same issue with my Accord. When I want windows open while driving, I usually open the front passenger window and rear driver's each about half way . . . just right for cruising without the wind being in my face.

My 2005 Acura TSX used to do the same thing when I hit over 100kmph. The second the rear window(s) opened the car would start vibrating and a noise would occur.
