THERE IS AN AIR FLOW IN THIS AREA, AND CAN FAN OR START FLAMES IN THIS AREA IF IT OCCURS WHILE DRIVING. VERY DANGEROUS! THIS IS MY SECOND REPORT. *TR

WHILE DRIVING MY 2006 HUMMER H3 ON A BACK COUNTRY PAVED RD, DOING THE POSTED SPEED LIMIT, MY SIDE CURTAIN AIR BAGS ON BOTH SIDES DEPLOYED FOR NO REASON. THE ROAD HAD ITS BUMPS AND STUFF LIKE ANY ROAD BUT NOTHING TO CRAZY. THE VEHICLE WAS NOT IN A CRASH OR ROLLING OVER AND SHOULD NOT HAVE DEPLOYED AIRBAGS. THIS SITUATION COULD HAVE BEEN DEADLY, THANK GOD IT WASN'T. GM IS SENDING OUT A THIRD PARTY INSPECTOR TO LOOK AT THE VEHICLE. I HAVE A FEELING THIS WILL END UP IN COURT. THERE HAS BEEN MANY OF THESE CASES AND GM HAS NOT CORRECTED WITH RECALL OR NOTHING. SOMETHING NEEDS TO BE DONE AND FORCE THEM TO DO THE NEEDED RECALL ON THIS. *TR

Apr 30, 2010
GM IS RECALLING CERTAIN MODEL YEAR 2006 THROUGH 2010 HUMMER H3 VEHICLES. SOME OF THESE VEHICLES HAVE A CONDITION IN WHICH THE INTEGRAL CLIP-TABS ON THE LOUVER ON THE HOOD MAY FRACTURE, CAUSING THE HOOD LOUVER RATTLE AGAINST THE HOOD AND BECOME LOOSE. IF THIS INDICATOR IS UNNOTICED, ADDITIONAL CLIPS COULD FRACTURE AND THE HOOD LOUVER COULD DETACH FROM THE VEHICLE.
Consequence & remedy
Consequence: IF THE VEHICLE IS BEING DRIVING WHEN THIS OCCURS, IT COULD STRIKE A FOLLOWING VEHICLE AND CAUSE INJURY AND/OR PROPERTY DAMAGE.
Remedy: DEALERS WILL APPLY AN ADHESIVE TO THE HOOD LOUVER TO SECURE IT TO THE HOOD. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON APRIL 12, 2010. OWNERS MAY CONTACT HUMMER AT 800-732-5493 OR AT THE OWNER CENTER AT WWW.GMOWNERCENTER.COM.
06V417000 · Air Bags:frontal
Oct 31, 2006
CERTAIN VEHICLES ORIGINALLY BUILT WITH CLOTH SEATS THAT WERE EQUIPPED WITH AN AUTOMATIC AIR BAG PASSENGER SENSING SYSTEM AND LATER REUPHOLSTERED WITH AFTERMARKET LEATHER SEAT COVER KITS ARE INVOLVED. TESTING HAS INDICATED THAT THE AFTERMARKET LEATHER SEAT COVERS CAN CAUSE THE PASSENGER SENSING SYSTEM TO MALFUNCTION.
Consequence & remedy
Consequence: IF THE PASSENGER SENSING SYSTEM MALFUNCTIONS, THE FRONT AIR BAG ON THE PASSENGER SIDE MAY BE DISABLED WHEN IT SHOULD BE ENABLED, OR ENABLED WHEN IT SHOULD BE DISABLED. IN EITHER CASE, IN THE EVENT OF A CRASH THAT REQUIRES AIR BAG DEPLOYMENT, A FRONT PASSENGER'S LEVEL OF INJURY MAY BE INCREASED.
Remedy: BECAUSE A REPLACEMENT LEATHER SEAT COVER THAT IS COMPATIBLE WITH THE PASSENGER SENSING SYSTEM IS NOT AVAILABLE, GENERAL MOTORS (GM) WILL REPURCHASE THESE VEHICLES IN ACCORDANCE WITH THE TERMS STATED IN GM'S LETTER TO OWNERS. THE RECALL BEGAN ON NOVEMBER 6, 2006. OWNERS SHOULD CONTACT GM AT 1-877-477-1022 TO BEGIN THE PROCESS OF REPURCHASING THEIR VEHICLE.
