HUMMER Complaints

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.

REAR WINDOW ON DRIVER SIDE, CABLE SNAPPED LESS THAN A YEAR AGO. IT WAS RAINING HEAVY AND I HAD TO RIDE WITH THE WINDOW DOWN FOR 13 HOURS TILL I GOT HOME. TONIGHT, IT'S THE 4TH OF JULY, TOOK MY KIDS TO SEE FIREWORKS.. ROLLED THE WINDOW DOWN FOR THEM TO WATCH, HEARD A POP. NATURALLY I WAS OUT OF TOWN AND HAD TO TO RIDE HOME LIKE THAT..

I STOPPED AT GAS STATION FOR FUEL. VEHICLE WOULD NOT START FOR APPROXIMATELY 10 MINUTES AFTER FUELING UP. THEN IT STARTED. APPARENTLY THIS IS A WIDE SPREAD PROBLEM WITH THE HUMMER, AS I HAVE READ A NUMBER OF INCIDENTS REPORTED ON LINE WITH SAME ISSUE.

SIR/MA'AM, I AM WRITING TO COMPLAIN ABOUT THE 2007 HUMMER H3 SECURITY SYSTEM NOT ALLOWING THE VEHICLE TO START UNDER CERTAIN CONDITIONS. I MAINTAIN MY VEHICLE TO HIGH STANDARDS AND OVER THE LAST 8 MONTHS HAVE HAD ISSUES STARTING MY HUMMER. WHEN THE HUMMER DOES NOT START, YOU MUST WAIT 10-15 MINUTES TO EVEN ATTEMPT TO RESTART. THE VEHICLE WILL TURN OVER, BUT NO FUEL IS SENT TO THE ENGINE TO START. IF IT DOESN'T START AGAIN, YOU MUST WAIT ANOTHER 10-15 MINUTES. THE LATTER HAS HAPPENED TO ME 5 OR 6 TIMES IN JUST THE LAST 2 MONTHS. THERE HAVE BEEN NUMEROUS COMPLAINTS TO GM ABOUT THIS EXACT ISSUE, AND HAS FALLEN ON DEAF EARS. MANY VEHICLE FORUM USERS COMPLAIN OF THE EXACT ISSUE AS WELL, WITH ZERO ASSISTANCE FROM GM AS SEEN HERE: HTTPS://WWW.CARGURUS.COM/CARS/DISCUSSION-C8039_DS531571 I AM CONCERNED THAT IF THE SPORADIC SECURITY LOCKDOWN (PASSLOCK) OCCURS WHILE DRIVING, FUEL IS CUT OFF FROM THE RUNNING ENGINE, SPEED/STEERING/BRAKING WILL BE MINIMIZED, AND THE POSSIBILITY OF A CRASH IS INCREASED EXPONENTIALLY. PLEASE ADVISE GM THERE NEEDS TO BE A FIX FOR THIS AND ENSURE THEY COMPLY! THANK YOU FOR YOUR TIME. I BELIEVE MY PHOTOS OF THE BLOWER MOTOR FAN RESISTOR BEING BURNT HELPED GET GM ISSUE A RECALL, AND I HOPE THIS WILL URGE THEM TO FIX AS WELL

TL* THE CONTACT OWNS A 2006 HUMMER H3. WHILE DRIVING 60 MPH, THE LOUVER IN THE CENTER OF THE HOOD SHATTERED INTO PIECES, STRIKING THE WINDSHIELD AND THE TOP OF THE VEHICLE. THE CONTACT WAS ABLE TO MANEUVER TO THE SIDE OF THE ROAD. THE VEHICLE WAS TAKEN TO THE DEALER (HOFFPAUIR FORD, 902 N KEY AVE, LAMPASAS, TX 76550, (800) 460-4171) WHERE IT WAS DIAGNOSED THAT THE LOUVER NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED.

TL* THE CONTACT OWNS A 2009 HUMMER H3. WHILE DRIVING APPROXIMATELY 70 MPH, THE HOOD LOUVER DETACHED FROM THE HOOD AND LANDED ON THE ROADWAY. THE VEHICLE WAS REPAIRED BY THE DEALER (SUBURBAN CADILLAC OF TROY, 1810 MAPLELAWN DR, TROY, MI 48084, (248) 643-0070) PER NHTSA CAMPAIGN NUMBER: 10V179000 (STRUCTURE) IN 2010.

THE RIGHT ABOVE THE WINDSHIELD ON PASSENGER SIDE LEAKS WATER INTO THE CAB OF THE VEHICLE. WATER RUNS DOWN THE WINDOW TO THE DASH BOARD GOES BEYOND THE DASH DOWN THROUGH THE FIREWALL AND IN THE GLOVE BOX THRU THE GLOVE BOX AND DRIPS ONTO THE AIR COMPRESSOR CAUSING THE PART TO BREAK, THUS CAUSING THE DASH BOARD AND ALL THE COMPONENTS TO OVER HEAT BECAUSE THE FAN DOES NOT WORK TO COOL THE ELECTRICAL CIRCUIT BOARDS ASSOCIATED WITH. ALL THE DASH BOARD FEATURES. PLUS THE AIR CONDITIONER DOES NOT WORK EITHER AS A RESULT OF THE LEAK. MOLD AND MILDEW ALL THROUGHOUT THE CAR UNDER THE DASH AND THE SMELL IS AWFUL.

ABS /. TRACTION CONTROL. BOTH LIGHTS ON AT THE MESSAGE CENTER OF THE DASH BOARD. SIMULTANEOUSLY THESE TWO LIGHT COME ON AND OFF INTERMITTENTLY. MEANING THEY COME ON TOGETHER, SOMETIMES WHEN I HIT A SPEED BUMP AND THEN THEY GO OUT FOR SOMETIMES 1 MONTH OR 4 MONTHS EACH TIME RANDOMLY. ALWAYS WHEN THE CAR IS MOVING OR IN OPERATION.

THE ENGINE COMPLETELY SHUT OFF WHILE DRIVING ON A MAJOR HIGHWAY. THE STEERING WHEEL LOCKED UP AND THE CAR CAME TO A STOP. LUCKILY, EACH TIME THIS OCCURRED, I WAS ABLE TO PULL OVER TO THE SHOULDER. THERE WERE NO ERROR LIGHTS THAT CAME UP ON BOTH OCCASIONS OF THIS HAPPENING. THE BATTERY CONTINUE TO DIE, EVEN AFTER BEING REPLACED THREE TIMES IN 6 MONTHS!
