2008 Chevrolet Trailblazer Seat belts Problems

Both side curtain airbags deployed while driving down the street. The driver's seatbelt tightened then locked up. There was no obvious reason for the airbags to deploy. the vehicle was taken to a Chevy dealer to see if it was on recall list but they said it was not. Vehicle was referred to a body shop for estimate for repairs...$6,435.00....if you can find the parts. driver was shaken up by the deployment but not injured.

WHILE I WAS DRIVING DOWN THE ROAD, BOTH CURTAIN SIDE AIR BAGS DEPLOYED AT SAME TIME. THERE WERE NO OTHER CARS ON THE ROAD, SO I WAS ABLE TO STOP THE VEHICLE WITHOUT CAUSING AN ACCIDENT. THE AIRBAG ON THE DRIVER SIDE PUSHED ME OVER SO HARD THAT IT BROKE MY CENTER CONSOLE. MY LOWER BACK STILL HURTS, BUT I AM HOPING THE PAIN WILL GO AWAY. MY LEFT EAR IS STILL RINGING AND HAS NOT RETURNED TO NORMAL HEARING YET CAUSED FROM THE EXPLODING NOISE FROM THE AIRBAG DEPLOYMENT. BOTH OF THE FRONT SEAT BELTS WILL NOT WORK AND THE DASHBOARD HAS SO MANY LIGHTS GOING OFF, I DON'T KNOW IF THERE ARE ANY OTHER PROBLEMS. THE DEALERSHIP THAT I PURCHASED THE VEHICLE FROM SAID THE DAMAGES COULD RUN AS MUCH AS $4000.00 WHICH I DO NOT HAVE AND MY INSURANCE DOESN'T COVER THIS SINCE THERE WAS NO ACCIDENT THAT CAUSED THIS. THE DEALERSHIP SERVICE DEPT. ALSO SAID THEY HAVE NEVER HEARD OF ANY VEHICLES DOING THIS. AFTER RESEARCH, I SEE THAT THIS HAS HAPPENED ALOT. *TR

ON MAY 24, 2012- I WAS TRAVELING OUT OUR MILE LONG GRAVEL DRIVEWAY. HALF WAY DOWN THE DRIVEWAY THE SIDE CURTAIN AIRBAGS ON BOTH SIDES DEPLOYED. THERE WAS NO CRASH- THEY JUST CAME OUT. I CONTACTED GM. THEY FINALLY SENT OUT A 3RD PARTY INVESTIGATOR TO INVESTIGATE THE VEHICLE. THEY DETERMINED THAT THE VEHICLE HAD A ROLL-OVER EVENT. THE VEHICLE DID NOT ROLL-OVER. GM TOLD ME THAT IT WAS AN INSURANCE ISSUE. INSURANCE COMPANY SAYS IT IS A MECHANICAL ISSUE AND WAS GM'S PROBLEM TO FIX. AT THIS TIME THE VEHICLE STILL SITS WITH BOTH SIDE AIRBAGS OUT AND THE FRONT DRIVER AND PASSENGER SEATBELTS ARE LOCKED IN PLACE. VEHICLE IS NOT DRIVABLE. *TR

THIS COMPLAINT IS IN CONJUNCTION WITH MY FALSE AND DELAYED SIDE CURTAIN AIRBAG DEPLOYMENT, REPORT DATE OF MARCH 25, 2009. I JUST DISCOVERED THAT BOTH FRONT SEAT BELT SYSTEMS MUST BE REPLACED. THE DRIVERS SIDE SEAT BELT IS LIMP. THE PASSENGER SIDE SEAT BELT IS SO TIGHT IT NOT ONLY BROKE TOP OF THE BELT HOUSING ON TOP OF THE SEAT (PIECES), THE BELT IS SO TIGHT IT IS DEFORMING THE SEAT. I CANT IMAGINE WHAT THIS WOULD HAVE DONE TO A PASSENGER, HAD I HAVE HAD ONE IN THAT SEAT. *TR
