Air pressure noise when windows down

[mediaspacetj]

Hi, we bought a 2011 Aurion Touring about 6 months ago. Very happy with it.

We've found that when a window is opened, particularly in the rear we get a wopwopwopwopwop air pressure sound and feel that is hard on the ears. It starts around 40kph and gets worse the faster you travel.

Anyone have a similar issue? What causes it and how can we fix it short of only rolling down the window about an inch?

Thanks for any insights you can give.

Yep, same here with an '07 Touring. I guess its just the arodynamics of the interior of the car. Perhaps those window rain/plastic coverings would change it?? I just let my aircon chill me. lol.

This is particularly prominent when rear windows are opened, particularly both rear windows at higher speed.
