To whom it may concern my wife and I own a 2006 Pontiac Torrent there is an issue concerning the air flow into the vehicle mainly when only one rear window opened. With only one or both rear windows rolled down there is a pulsating pressure of air that is quite severe when driving 40mph and over. This also occurs with only front window down at lower speeds but not as severe. My concern being damage to your eardrum, infants being more vunerable and not able to tell, I know it hurts my ears. Have brought this to the service peoples attention and their response being " nothing we can do about it, its in the design of the vehicle".
