96 reports2006 HUMMER H3 SECURITY LOCKOUT ENGAGES RANDOMLY. HAVE REPEATED OCCURRENCES OF ENGINE NOT ENGAGING UPON ENTRANCE TO VEHICLE. HAVE TO WAIT 10 MINUTES BEFORE IGNITION WILL WORK AGAIN. PROBLEM OCCURS APPROXIMATELY 3 TIMES A WEEK. RESEARCHING ONLINE I HAVE FOUND MULTIPLE COMPLAINTS OF THE SAME ISSUE WITH THE 2006 H3.
WHILE THE VEHICLE IS STATIONARY AND UPON ENTERING THE VEHICLE, THE VEHICLE WILL RANDOMLY NOT PERMIT YOU TO START THE VEHICLE. AFTER SEARCHING ONLINE ON SEVERAL FORUMS, I SEE THAT THOUSANDS UPON THOUSANDS OF PEOPLE ARE HAVING THIS SAME ISSUE WITH HUMMER MODELS, NOT JUST THE H3.

WHILE THE VEHICLE IS STATIONARY AND UPON ENTERING THE VEHICLE, THE VEHICLE WILL RANDOMLY NOT PERMIT YOU TO START THE VEHICLE. AFTER SEARCHING ONLINE ON SEVERAL FORUMS, I SEE THAT THOUSANDS UPON THOUSANDS OF PEOPLE ARE HAVING THIS SAME ISSUE WITH HUMMER MODELS, NOT JUST THE H3. IT SEEMS THAT THE IGNITION IS BELIEVING YOU ARE A BURGLAR, AND IT LOCKS YOU OUT FOR 10 MINUTES. AFTER THE 10 MINUTES HAVE PASSED, YOU CAN START THE CAR WITH NO PROBLEM. THE ONLY WAY TO GET AROUND THIS (PER GM) IS TO REPLACE THE IGNITION, BUT SINCE THERE ARE SO MANY COMPLAINTS OF THIS I BELIEVE IT SHOULD BE A RECALL INSTEAD OF CONSUMERS HAVING TO PAY FOR THIS FLAW.

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.

Consequence & remedy
Consequence: A MISPRINTED LABEL COULD LEAD TO IMPROPER VEHICLE LOADING SPECIFICATIONS OR TIRE INFLATION WHICH COULD RESULT IN A TIRE FAILURE, INCREASING THE RISK OF A CRASH.
Remedy: OWNERS WILL BE PROVIDED WITH CORRECTED LABELS AND INSTALLATION INSTRUCTIONS. AT THE CUSTOMER'S OPTION, A DEALER CAN INSTALL THE LABEL FOR THEM. THE RECALL BEGAN ON MARCH 31, 2006.
