TL* THE CONTACT OWNS A 2005 HUMMER H2. THE CONTACT STATED THAT THE AIR BAG SERVICE WARNING INDICATOR REMAINED ILLUMINATED WHILE DRIVING, WHICH WAS A SAFETY CONCERN. THE VEHICLE WAS TAKEN TO A DEALER (HALEY BUICK GMC, 9831 MIDLOTHIAN TURNPIKE, RICHMOND, VA 23236, (804) 320-9054) WHERE IT WAS DIAGNOSED THAT THE SENSING DIAGNOSTIC MODULE FOR THE FRONT DRIVER'S SEAT NEEDED REPLACEMENT.

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.
HEATER FAN CONTROL KNOB OVERHEATS. WHEN HEATER WAS IN OPERATION THE HEATER CONTROL KNOB AREA ABOVE AND BELOW THE CVERY HOT TO THE TOUCH, HEATING UP RADIO AND OTHER FRONT DASH COMPONENTS. PRIOR TO THIS, INSTRUMENT PANEL GAUGES STOPPED WORKING COMPLETELY FOR GAS GAUGE AND RPMS, AND STOPS WORKING INTERMITTENTLY FOR SPEEDOMETER (OCCURRED AROUND 100K MILES).

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.
GET IN START THE VEHICLE, SEAT HEAT COMES ON. I TURN IT OFF IT COMES BACK ON SECONDS LATER. IT WILL NOT GO OFF AND STAY OFF. IT DOES NOT MATTER IF IM DRIVING OR PARKED. SEAT HEAT COMES ON BY ITS SELF.
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.
AIRBAG LIGHT ON AND CAR NOT IN ACCIDENT. JUST WANT MY VEHICLE FIXED AS I'M SCARED TO DRIVE IT AND THE BAG COMES OUT. THE DOOR WON'T CLOSE.MY PHONE NUMBER IS [XXX]. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
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.
THERE IS A LEAK CAUSED BY THE TUBES CHANNELING WATER FROM THE SUNROOF. DURING HEAVY RAINS WATER POOLS ON THE DRIVER AND PASSENGER SIDE FLOOR.
CAR WILL NOT START DUE TO PASS-LOCK OR OTHER MALFUNCTION COMPONENT. MUST TRY AND FAIL AND THEN WAIT FOR CAR TO 'RE-SET' EACH AND EVERY TIME THE VEHICLE IS TRIED TO BE STARTED. AFTER 10 MINUTES THE CAR'S ENGINE COMPLETELY KILLS, EVEN IF CAR IS IN MOTION. REPROGRAMMED KEYS AND THIS ONLY WORKED FOR A WEEK. NOW EACH AND EVERY DOOR LOCK, BACK HATCH LOCK, ETC... HAS FAILED. THE HATCH IS LOCKED CLOSED AND THE DOORS WILL ONLY UNLOCK OR LOCK PHYSICALLY WITH YOUR HAND. THE SPEEDOMETER FAILS INTERMITTENTLY, ALONG WITH OTHER GAUGES WORKING ONLY SOMETIMES.
A PROBLEM WITH NEARLY ALL HUMMER H2S IS ROOF LEAK, THERE IS A DRAINAGE SYSTEM TO DRAIN THE WATER THRU THE VEHICLE. THIS CLOGS UP PERIODICALLY AND THE WATER DRAINS INTO THE VEHICLE AND ENDS UP ON THE FRONT FLOORBOARD. THE AIRBAG SENSOR DIAGNOSTIC MODULE IS MOUNTED ON THE FLOORBOARD DIRECTLY UNDER THE DRIVERS SEAT. IF THIS GETS WET, WHICH IT DOES, THE MODULE IS RUINED AND RENDERS THE AIRBAGS INOPERABLE. THIS HAS HAPPENED TO MY VEHICLE AND I AM SURE MANY OTHERS. IF THIS MODULE IS NOT IN WORKING ORDER IT HAS TO BE REPLACED, HOWEVER, GENERAL MOTORS HAS DISCONTINUED MAKING THE AIRBAG SENSOR DIAGNOSTIC MODULE FOR THE 2005 HUMMER H2 MODEL YEAR!. I AM SURE I AM NOT THE ONLY PERSON (OWNER) CAUGHT UP IN THIS SITUATION. THE VEHICLE IS STILL OPERATIVE AND DRIVABLE. AIRBAG SENSOR DIAGNOSTIC MODULE SHOULD BE AVAILABLE AND MANUFACTURE SHOULD ENSURE IT IS AVAILABLE. THE VEHICLE IS ONLY 10 YEARS OLD AND IF I OWNED A PRIOR YEAR THE MODULE IS STILL AVAILABLE. IT IS A SAFETY ISSUE BECAUSE OF WHERE IT IS LOCATED IN THE VEHICLE AND MANUFACTURE KNOWLEDGE OF LEAK PROBLEMS, AND ONLY ONE YEAR DISCONTINUED. I HAVE CONTACTED GENERAL MOTORS AND THERE REPLY WAS "SORRY". IT VERY APPARENT GENERAL MOTORS HAS NO REGARD FOR THE SAFETY OF THEIR CUSTOMERS!
