I OWN A HUMMER H3 2006 MODEL. I PURCHASED IT BRAND NEW. NO ACCIDENTS. THE ROOF POOLS WATER BECAUSE OF A FAULTY DRAINAGE SYSTEM. THE WATER THEN COMES OUT THROUGH THE ROOF IN LARGE AMOUNTS AND THROUGH THE SIDE WALLS AND EMERGENCY BRAKE. THIS CAN CAUSE AN ACCIDENT DUE TO THE LARGE AMOUNTS OF WATER SPILLING ONTO THE DRIVER, OR AN ELECTRICAL FIRE OR MECHANICAL MALFUNCTION. IT CAN ALSO CAUSE MOLD IN THE INTERIOR DUE TO LARGE COLLECTIONS OF WATER STAGNATING. THIS IS A KNOWN ISSUE THAT IS RECORDED IN GM FORUMS - YET THERE IS NO RECALL FOR THE FAULTY DRAIN PIPES. *TR

LAST WEEK I WAS DRIVING LOCALLY HOME WHEN MY H3 CAB FILLED WITH SMOKE BLOCKING MY VISION AND THE A/C BLOWER STOPPED...I NEARLY DROVE INTO A TREE...IF I HAD BEEN ON THE HIGHWAY AT SPEED, I WOULD BE DEAD. I TOOK THE CAR TO A LOCAL SHOP, AS CLOSE AS I COULD GET...ANYWAY MY DEALER WAS SHUT DOWN AS GM WENT INTO BANKRUPTCY. THE MECHANIC FOUND THAT A WIRING HARNESS CONNECTOR BURNED OUT, CREATING THE SMOKE AND CUTTING THE BLOWER OFF (SEE PHOTOS). I REPORTED THIS TO GM, ASKING THEM FOR REFUND OF COSTS AND TO INVESTIGATE THIS SERIOUS SAFETY MATTER. THEY REFUSED BECAUSE I AM OUT OF WARRANTY! I BELIEVE THEY ARE COVERING UP A SERIOUS MANUFACTURING FLAW...WHEN THE MECHANIC PHONED GM FOR THE WIRING HARNESS SECTION INVOLVED, THEY HAD IT IN STOCK READY TO GO...EVIDENTLY, GM KNOWS OF THIS FLAW. IF THIS PROBLEM IS NOT TAKEN SERIOUSLY, SOMEONE WILL BE KILLED BY IT! *TR UPDATED 08/20/09.*JB

I RECENTLY PURCHASED A 2006 H3. FROM THE DAY I BOUGHT THE CAR I HAVE NOTICED A WEIRD IDLE WHEN THE VEHICLE IS WARMING UP. UNTIL RECENTLY I THOUGHT IT WAS THE WAY THE VEHICLE RAN NORMALLY. I DECIDED TO HAVE THE VEHICLE INSPECTED BY A MECHANIC. AFTER BEING INSPECTED THE MECHANIC NOTICED THE VEHICLE'S VALVES WERE NOT SEEDED RIGHT FROM THE FACTORY, WHICH HAS CAUSED THE MISFIRE, WHICH CAUSES THE WEIRD IDLE. I NOW AM IN THE PROCESS OF CONTACTING HUMMER TO SEE IF THERE IS A SOLUTION TO THE PROBLEM. THE VEHICLE HAS ONLY 61870 MILES ON IT AND I DON'T FEEL THIS SHOULD HAVE HAPPENED THIS SOON IN THE VEHICLES LIFE. SERVICE BULLETINS HAVE BEEN WARRANTED AND I WOULD LIKE TO FIND A REASONABLE SOLUTION TO THE PROBLEM. *TR

ANOTHER CYLINDER HEAD HAS BEEN ORDERED FOR MY VEHICLE AND WILL BE FIXED UNDER WARRANTY. WHAT HAPPENS WHEN MY WARRANTY RUNS OUT A YEAR FROM NOW. I AM NOT CRAZY ABOUT A DEALER TEARING DOWN MY ENGINE AT THIS POINT. IT HAS NOT BEEN BROKEN IN YET. I THINK THE WHOLE ENGINE SHOULD BE REPLACED. I FEEL GM KNEW OF THIS ALL ALONG AND BUILT THESE SUV'S ANYWAY WITH THE HOPES THAT THE MOTORS WILL LAST UNTIL THE WARRANTY HAS EXPIRED. *TR

Official recalls
4Jul 1, 2015
General Motors LLC (GM) is recalling certain model year 2006-2010 Hummer H3 vehicles manufactured February 5, 2005, to May 24, 2010, and 2009-2010 Hummer H3T vehicles manufactured May 21, 2008, to May 24, 2010. In the affected vehicles, the connector module that controls the blower motor speed for the heating, ventilation and air conditioning system may overheat.
Consequence & remedy
Consequence: If the blower motor connector module overheats, it can increase the risk of a fire.
Remedy: GM will notify owners, and dealers will replace part of the blower motor connector and harness, free of charge. The recall began February 26, 2016. Owners may contact Hummer customer service at 1-800-732-5493. GM's number for this recall is 15042.
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.
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.
Dec 7, 2005
CERTAIN TRUCKS AND SPORT UTILITY VEHICLES FAIL TO CONFORM TO THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 110, "TIRE SELECTION AND RIMS." THESE VEHICLES WERE SHIPPED WITH TIRE AND LOADING INFORMATION LABELS LISTING AN INACCCURATE VEHICLE CAPACITY WEIGHT.
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. OWNERS MAY CONTACT BUICK AT 1-866-608-8080, CADILLAC AT 1-866-982-2339, CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, HUMMER AT 1-800-732-5493, PONTIAC AT 1-800-620-7668, SATURN AT 1-800-972-8876, OR ISUZU AT 1-800-255-6727.
