THE CONNECTOR MODULE THAT CONTROLS THE BLOWER MOTOR SPEED IN THE HEAT/VENT/AIR CONDITIONING (HVAC) SYSTEM MAY OVERHEAT UNDER EXTENDED OPERATIONAL PERIODS AT HIGH MEDIUM-HIGH BLOWER SPEEDS. IF THIS CONDITION OCCURS, THERE THE RISK THAT THE HEAT GENERATED COULD MELT THE PLASTIC SURROUNDING THE CONNECTOR MODULE, WHICH INCREASES THE RISK OF A FIRE. OURS HAS BEEN MISSED UP FOR 2 MONTHS. PLEASE HURRY AND GET THE PART. WE CAN NOT DRIVE IT BECAUSE IT OVERHEATS. WE HAVE HAD IT IN A SHOP THREE TIMES AND CAN NOT GET IT TO WORK. THANK YOU. RECALL IS 15V421 *TR

WHILE DRIVING I NOTICED HEAVY SMELL OF ANTIFREEZE.. I TOOK TO LOCAL SHOP AND WE NOTICED ANTIFREEZE ALL OVER ENGINE. RADIATOR HAD CRACK ON TOP. AFTER RESEARCH I SEE MULTIPLE COMPLAINTS ONLINE WITH OTHER HUMMER OWNERS SAME ISSUE. HAD TO REPLACE RADIATOR. MECHANIC SAID THER RADIATOR RUBS AND BOUNCES AGAINST THE FRAME CAUSING CRACK.

TL* THE CONTACT OWNS A 2008 HUMMER H3. WHILE DRIVING AT APPROXIMATELY 5 MPH DURING A RAIN STORM, THE WINDSHIELD WIPERS BECAME INOPERABLE WITHOUT WARNING. THE CONTACT PULLED OVER AND POWERED THE VEHICLE OFF AND BACK ON. WHEN THE VEHICLE WAS RESTARTED, THE WINDSHIELD WIPERS FAILED TO WORK. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE BODY CONTROL MODULE FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 81,000.

WITHOUT ANY WARNING, THE ENGINE BEGAN TO MISFIRE AND STALL OUT AFTER STARTING FROM A GREEN LIGHT. IT ONLY LASTED ABOUT 10 SECONDS. AFTER THIS, THE ENGINE QUIT MISFIRING AND BEGAN TO HAVE AN AUDIBLE WHINE COME FROM UNDER THE GEAR SHIFTER. THIS WAS SUBSEQUENTLY DIAGNOSED BY ELECTRONIC MEANS AS AN INTERMITTENT MISFIRE AND ACCELERATOR PEDAL POSITION SENSOR. AFTER EXAMINATION BY A MECHANIC, IN THE LOWER PORTION OF THE ENGINE A BOLT HOLDING IN PLACE ONE OF THE BALANCERS WORKED ITSELF FREE. THE ENTIRE BOLT WAS DISPLACED FROM ITS ORIGINAL LOCATION AND THE THREADS WERE PROTRUDING OUT OF THE PLATE BEHIND THE FLYWHEEL IN THE AREA OF THE REAR MAIN SEAL CAUSING A SIGNIFICANT LOSS IN OIL. UPON FURTHER INSPECTION AFTER THE ENGINE WAS REMOVED, MULTIPLE COMPONENTS APPEARED DAMAGED AS A RESULT OF THE BOLT GETTING STUCK IN ONE OF THE INTERNAL CHAINS. THE WHINING NOISE WAS A RESULT OF THE CHAIN RUBBING AGAINST THE REMAINS OF THE BOLT THAT WAS LODGED AND PARTIALLY EXPELLED FROM THE LOWER REAR OF THE MOTOR. FINALLY, TO BE CLEAR, THIS INCIDENT APPEARS TO BE THE RESULT OF A BOLT BEING IMPROPERLY TORQUED, MACHINED OR THE BALANCER BEING IMPROPERLY MACHINED AND MATCHED FOR THE BOLT. AGAIN, THE ENTIRE BOLT (INCLUDING THREADS) WAS FREE FROM THE COMPONENT IT WAS INSTALLED IN. *TR
