I have a situation which bugs me and I'm not sure if I'm the only one with this
"problem."
When driving down the road and the 2nd row door window is opened, I always get a LOUD air "thumping" noise which is severe enough to cause the front passanger seat viabrate forward and back about 1/2 inch. Window goes up and all's quiet again.
This is the first vehicle I've ever encountered this on. My GX is a 2006. Tell me this is not an engineered-in airflow and aerodynamic characteristic (flaw).

my wife has mentioned this same issue on our 2006 GX. I heard the thumping when I tried it but did not notice the front seats moving as much as you mentioned. Anyway, it would be nice if the 3rd-row side windows could be cracked open electronically from the front seats.... that would work.

None of the older cars used to do this. Many of the newer ones do. It's the rear windows! Either styling is more important than aerodynamics or many carmakers think that nobody wants to drive around with the rear windows down anymore (kids safety, etc?). You're right "CVsGX470!" It sounds just like a helicopter.

As newer cars get more aerodynamic, this has become a problem. When you crack a window in the rear, you are actually creating a vaccum inside your car. It is almost like pour a bottle of liquid into something, it will make a gulping sound. If you open up a vent hole on the opposite side of the bottle neck, the sound will go away. That vent hole is created when you crack open your front window.

Too bad these aren't electric...

The rear vents in the GX s/b electric. I had electric on the Toyota Sienna and used it all the time. We should also be able to control AC and heat in back rows from the front. The rear doesn't get hot/cool enough that fast with just the front on, but this is a different topic.

I had to memorize the buttons for the rear cooling system when i am in the GX without passengers. I can reach behind the center console and turn on/turn up/turn cooler/warmer by feel. This is pretty stupid in a 55K luxury vehicle.

So too is the non-electric venting windows in the rear. Hell, my neighbors Chrysler T&C minivan at the very least has this.
Don't even get me started on the bluetooth phonebook stuff...

Maybe off topic here, but when you are driving around check out the newer cars when their sunroofs are open. The flap that sticks up when you open the roof now has a difuser style design to it. This is the ultimate fix...

Isn't it just simple physics? If you have one window open, where is the air/wind going to coming out?
It's just going to circulate back to that one window cracked open.
That's why everytime when 1 passenger open the window, I have to open my window
