I purchased a 2008 TB3SS on Dec. 27th 2008 and was very satisfied with it untill Mar. 1st 2009 when my side curtain airbags deployed several seconds after completing an abrupt maneuver (no impact) to avoid another drivers (posted) illegal turn. I was driving straight down the road at about 35-40 mph when the passenger curtain bag rapidly deployed, (I first thought that I was caught in gunfire) then noticed the drivers curtain bag inflating as if in slow motion, and my seat belt locked up. I was trying to pull the bag back so I could see to turn left, out of the right hand lane of a four lane road to exit the roadway when I then rubbed the curb with both right tires, causing a right front flat. I was like in shock or something, talking with Onstar since the deplosion, untill I parked. Vehicle was towed to dealer with 1066 miles on it. G.M. after conducting an investigation, has determined that I experinced a near rollover situation (pure chicken poop) and therefore declined any warranty or other assistance. Furthermore the drvers seatbelt is now stuck loose. I later noticed the passenger seatbelt retracted so tight that it broke The belt housing on top of the seat (pieces) and has clearly deformed the leather seat. I can only imagine what may have happened to a passenger or a child, if there were one sitting in that seat, through what has now become an ordeal.
