ENGINE
VEHICLE HAS 133,000 MILES. IT HAS NOW EXPERIENCED AN EXHAUST MANIFOLD GASKET LEAK DUE TO BROKEN BOLTS. THIS IS CAUSING NOISE FROM THE ENGINE AREA, AND IS UNSAFE DUE TO THE LEAK OF HOT GASES BEING RELEASED FROM THE ENGINE AT THE POINTS OF FAILURE (BROKEN BOLTS). THIS MAY BE AN EPA CONCERN AS WELL, AND COULD ALSO LEAD TO FAILURE OF CATALYTIC CONVERTER. REPAIR ESTIMATE IS $1,300. AN ONLINE SEARCH YIELDS HUNDREDS OF OTHER RESULTS WITH SAME FAILURE AND COMPLAINT ON ALL GM V8 ENGINES FOR YEARS 1999-2007. THIS AFFECTS THE 4.8L, 5.3L, AND 6.0L MODELS. THIS IS A DESIGN FAILURE AND THE AFFECTED VEHICLES WITH THESE ENGINES SHOULD BE RECALLED.

AIR BAGS
TAKATA RECALL HASN'T INCLUDED BUT SHOULD HAVE INCLUDED THE H2 HUMMER 2005. THIS LIGHT IS ON CONSTANTLY. FEEL VERY UNSAFE DRIVING IT. NOW, BECAUSE THEY ARE TRYING TO SAY IT'S THE CONSUMERS RESPONSIBILITY. I WILL TAKE THIS MATTER TO THE NEWS STATIONS IF I HAVE TO. THAT'S TOTALLY RIDICULOUS. THE VEHICLE WAS PARKED AND WHEN WE GOT INTO IT TO LEAVE THE LIGHT WAS ON AND BLINKING AND WOULD NOT GO OFF.

AIR BAGS, AIR BAGS:SENSOR:OCCUPANT CLASSIFICATION, AIR BAGS:FRONTAL:SENSOR/CONTROL MODULE
THE SDM (SENSING AND DIAGNOSTIC MODULE) ON MY 2005 HUMMER H2 IS NOT WORKING AND IS CAUSING MY AIR BAGS TO NOT WORK, AND ALSO CAUSES OTHER MODULES TO NOT BE ABLE TO COMMUNICATE AND CAUSE MY GAUGES AND OTHER ELECTRICAL ACCESSORIES TO NOT OPERATE (WINDOWS, LOCKS, ETC.) MANY OTHER HUMMER H2 OWNERS ARE HAVING THIS SAME PROBLEM. A NEW SDM WOULD FIX THE ISSUE, BUT GM FOR SOME REASON HAS DISCONTINUED MANUFACTURING THIS MODULE. WHY WOULD GM STOP MAKING A SAFETY RELATED ITEM FOR VEHICLES THAT ARE ONLY AROULD 10 YEARS OLD WITH MANY STILL ON THE ROAD. SO, NOW WE MUST DRIVE IT WITH THE AIR BAGS MOST LIKELY NOT GOING TO DEPLOY IN A CRASH.

AIR BAGS
THERE HAS TO BE A RECALL DONE ON THE 2005 HUMMER H2 AIRBAG MODULE. WHEN IT RAINS THE WATER GETS IN TO VEHICLE FROM THE DRIVER SIDE. I SEE A LOT OF COMPLAINTS FROM OTHER PEOPLE THAT HAVE THE SAME ISSUE. I HAVE CURRENTLY ONLY 61,000 MILES ON MY HUMMER H2. NEVER GOT IN A ACCIDENT. ONLY ISSUE IS THE WATER COMING IN FROM THE DRIVER SIDE AND DAMAGED THE AIR BAG MODULE. THE PART # IS 12249649, AND IT ONLY WORKS ON THE 2005 NO OTHER YEAR MODULES WILL WORK. THE PART IS DISCONTINUED FROM GM.

AIR BAG CONTROL MODULE NLA OEM 12249649. AFTER A RAIN I STARTED UP MY PARKED VEHICLE THE SERVICE AIR BAG LISTED IN THE DRIVER INFORMATION CENTER AS WELL AS THE RED WARNING LAMP TURN AND STAYED ON I AM THE ORIGINAL OWNER AND HAVE NEVER BEEN IN ANY CRASH. TOOK TO BOTH GM DEALER AND INDEPENDENT SHOP WITH THE SAME RESPONSE OF A REPLACEMENT WAS NOT AVAILABLE. IN MY RESEARCH I HAVE FOUND THE SAME ISSUE WITH OTHER 2005 OWNERS AND HAVE CONTACTED THE GM HELP LINE (CASE NUMBER 8-2560253832) TO NO AVAIL. MY LOCAL GM DEALER TRIED SEVERAL LEADS BUT WERE ALL DEAD ENDS. PREVIOUS YEARS OF THIS SAME MODEL VEHICLE HAVE THIS COMPONENT AVAILABLE BUT WILL NOT FIT THE 2005 YEAR MODEL AS I AM TOLD.
