IN AN EMERGENCY SITUATION, MY SHOE HANGS UP ON THE BACKSIDE OF THE BRAKE PEDAL AND I HAVE TO TURN MY FOOT SIDEWAYS TO GET IT OUT FROM UNDER THE PEDAL. THIS IS A VERY DANGEROUS AND ANNOYING PROBLEM THAT I AM AFRAID OF. I CAN'T FIX THIS PROBLEM MYSELF AS THE DESIGN IS THE CAUSE OF THE PROBLEM. *JB

I HAVE TWO 2006 H3 HUMMERS BOTH WITH THE 5 SPEED MANUAL TRANSMISSION. UPON ACCELERATION FROM A STOPPED POSITION IN FIRST GEAR, DEPRESSING THE CLUTCH FOR THE SHIFT INTO 2ND GEAR THE ENGINE RPMS REVS TO ABOUT 4000 AND STAYS THERE. SHIFTING INTO 2ND GEAR & RELEASING THE CLUTCH THE RPMS DROP BACK DOWN. ACCELERATING TO ABOUT 3000-3500 RPMS, DEPRESSING THE CLUTCH, AGAIN THE RPMS CLIMB TO AROUND 4000 AND STAYS THERE. THE SAME THING OCCURS DURING UP SHIFTS ... THIS HAS HAPPENED NO LESS THAN 7 TIMES ON ONE H3 AND 5 TIMES ON THE OTHER H3. THE HUMMER DEALER CAN FIND NO STORED CODES, AND CAN NOT DUPLICATE THIS. GM HAS BEEN NOTIFIED, BUT NOTHING HAS BEEN DONE TO REPAIR THIS PROBLEM BECAUSE THE DEALER CAN NOT SUPPLY DEFECT CODES. THIS HAS BEEN GOING ON SINCE AUGUST '06 WITH NO END IN SIGHT. I HAVE ASKED THE ECU BE EITHER REFLASHED OR REPLACED AND WAS TOLD IT WAS TOO COSTLY TO JUST PUT PARTS IN WITHOUT ANY CODES. I BELIEVE THE SOFTWARE COULD BE CORRUPTED. AND IS NOT AWARE ANYTHING IS WRONG. THUS THERE ARE NO CODES. *JB

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.
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.
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.
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.
