    Wind Buffeting

    My wife mentioned that she inadvertently lowered the rear window in her ATS when traveling about 50 mph and experienced severe wind buffeting throughout the car. I drove the car and lowered both rear windows when traveling about the same speed and noted severe low frequency booming and buffeting. I was just curious if this has been mentioned before or if anyone else has noticed this. It was extremely loud and distracting. Obviously we normally don't drive with the rear windows down and my wife loves her car but I wonder if this is a normal occurrence. I also tested my CTS and it also has some buffeting under the same circumstances, but not quite as severe, so it must be a common phenomenon.

    I think that's mentioned in the manual. The aerodynamics of the car I'd extremely well engineered. Back windows open interferes with it in a certain way that causes the booming. Completely normal

    I have had the same issue with other cars going back to 2005. It's not unique to Cadillac. FYI, before 2005 I was driving 2-door pickups.

    i know what hes talking about. if u have ur front windows closed and the back windows open, theres a very booming, low frequency buffeting sound. i know its not unique to cadillac obviously. but most cars ive been in didnt do that. so i guess hes not used to it thats why hes concerned.

    Thanks to most of you for your responses. I checked page 2-21 of the Owners Manual which refers to a "pulsing sound" when either rear window is down and the front windows are up. This is obviously not the way we normally drive but the extent of the buffeting aroused our curiosity. We have chalked it up to vehicle aerodynamics. Regards.

    Remember all the older cars (especially coupes) that had solid unmovable rear windows. That design stopped the noise level until people complained about those windows poping out (on a fairly regular basis). Those cars were primarily entry level cars and not lux cars, methinks.

    My Audi A4 produced the same acoustic resonance with sunroof open and one front window open. Audi sent out a bulletin advising owners to open rear windows.

    Thank goodness someone finally posted about this. It's so sad to not be able to drive on the freeway with the windows open just because of this. With BMW coupes this was never an issue. With their sedans, the easy work around was to lower both front and rear windows. With caddy there is no work around. Still like the car.
