HUMMER Complaints

ROUGH IDLE, ENGINE LIGHT APPEARS. IN PAST HAVE BEEN TOLD HAVE BEEN TOLD GAS CAP RELATED OR POSS THERMOSTAT OR INTERMIT MISFIRE. TODAY DEALERSHIP SAYS CYLINDER #2 NOT WORKING. NEED TO REPLACE. AT A COST OF $3000+. RELATED TO L52 ENGINE CONCERNS & INTAKE VALVE SEATS. INCLUDING COLORADO & CANYONS. WHY ARE SOME RECALLED, AND/OR FIXED ON MANUFACTURER'S DIME, BUT NOT OTHERS? GM KNEW OF CONCERN, (THUS CHANGED TO LLR ENGINE). MINE FITS THE YEAR AND WELL BELOW THE VIN #. WHY SHOULD 287591 H3 OWNERS HAVE TO PAY FOR GM'S MISTAKE? *TR

MY VEHICLE'S WARRANTY WHICH I PURCHASED SEPARATELY HAD JUST EXPIRED BUT I STILL WENT BACK TO DEALER AS THE NOISE I HAD REPORTED TO THEM UNDER WARRANTY WAS NOW MORE APPARENT. TURNS OUT IT WAS DUE TO BROKEN OFF EXHAUST HEADER BOLTS.NOW I AM OUT OF WARRANTY, DEALERSHIP WILL NOT FIX. I HAVE 1 BROKEN ON DRIVERS SIDE AND 3 ON PASSENGER SIDE. NOW MY CHECK ENGINE LIGHT IS ON SHOWING AN OXYGEN SENSOR FAILURE OR CATALYTIC CONVERTER. AFTER RESEARCHING THE INTERNET THIS PROBLEM IS AFFECTING THOUSANDS OF PEOPLE. SOMETHING NEEDS TO BE ADDRESSED !! *TR

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

TL* THE CONTACT OWNS A 2007 HUMMER H3. THE CONTACT STATED THAT THE VEHICLE FAILED TO START AND THE SECURITY WARNING LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE THE TECHNICIAN WAS UNABLE TO DETERMINE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 85,000.

ONE DAY WHEN I WENT TO TURN ON THE AIR CONDITIONER, THE AC WOULDN'T COME ON. WHEN I TURNED THE CONTROL KNOB TO 4, I COULD HEAR A CLICKING UNDER THE GLOVE BOX. ON CERTAIN DAYS THE BLOWER MOTOR WOULD WORK AND SOMETIMES IT WOULD QUIT RANDOMLY WHILE OPERATING. UPON INSPECTION I DISCOVERED THE BLOWER MOTOR RESISTOR HAD BECOME HOT AND MELTED TO THE CONNECTOR CAUSING CHAR TO BUILD UP INSIDE THE CONNECTION. *TR

STARTING IN OCTOBER 2013 MY SPEEDOMETER HAS NOT FUNCTIONED PROPERLY. IT DOES NOT DISPLAY THE CORRECT SPEED NO MATTER HOW FAST OR SLOW YOU ARE GOING. IT IS EITHER STUCK AT 0 OR BOTTOMS OUT OVER 120. I HAVE NO IDEA HOW FAST I AM DRIVING UNLESS I USE MY PORTABLE GPS THAT SHOWS SPEED. IF IT WASN'T FOR MY GPS THEN I COULD GET INTO AN ACCIDENT OR GET A TICKET BECAUSE I WOULD NOT KNOW HOW FAST I AM GOING. THIS IS A MANUFACTURE DEFECT AS I AM NOT THE ONLY HUMMER OWNER WITH THIS ISSUE. GM NEEDS TO FIX THIS PROBLEM ASAP. *TR

TL* THE CONTACT OWNS A 2007 HUMMER H3. THE CONTACT STATED WHILE ATTEMPTING TO START THE VEHICLE, THE PASS LOCK DISABLING SYSTEM LIGHT ILLUMINATED AND PREVENTED THE VEHICLE FROM BEING STARTED. THE CONTACT HAD TO WAIT APPROXIMATELY 10 MINUTES FOR THE VEHICLE TO SUCCESSFULLY RESTART. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE TECHNICIAN WAS UNABLE TO DUPLICATE OR DIAGNOSE THE FAILURE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 100,000.

I WAS PULLING OUT OF MY DRIVEWAY IN MY HUMMER H2 WHEN THE BRAKE PEDAL WENT TO THE FLOOR. I GOT OUT OF MY H2 AND NOTICED A LARGE AMOUNT OF BRAKE FLUID RUNNING OUT FROM UNDER THE REAR END NEAR THE LEFT REAR WHEEL. I LOOKED UNDER THE VEHICLE AND NOTICED A BRAKE LINE WAS RUSTED IN TWO. I CHECKED UNDER THE HOOD AND SAW THAT THE BRAKE FLUID RESERVOIR WAS COMPLETELY EMPTY. *TR

I FEEL THAT THIS KEY PROBLEM FALLING OUT OF THE IGNITION, KEY WILL NOT TURN ON OR OFF MAKING IT HARD TO CONTROL WHEN THE KEY IS IN THE IGNITION AND CAUSING IT NOT TO START. I HAD THIS SAME PROBLEM ON A 2003 ISUZU ASCENDER. ALSO THE "DRIVER INFORMATION CENTER" HAS QUIT WORKING RIGHT WHICH CONTROLS A LOT OF THINGS ON THE VEHICLE. I THINK IT IS A DEFECTIVE SWITCH FROM GM WHO ALSO BUILT MY 2003 ISUZU. *TR

I HAVE A 2007 H3 HUMMER WITH 81000 MILES. THIS PAST SUMMER I GOT INTO MY TRUCK AND PUT ON MY AIR CONDITIONING ON HIGH. NOTHING CAME OUT OF THE VENTS. BLOWER MOTOR WOULDN'T EVEN MOVE. I DID SOME RESEARCH ON THE TOPIC AND IT ALL LEAD TO A BURNT OUT BLOWER MOTOR RESISTER. I HAD PURCHASED A NEW ONE AND REPLACED IT TO FIND OUT THAT THERE WAS A SMALL FIRE IN THE PLUG FROM IT GETTING TO HOT. THIS IS A COMMON PROBLEM WITH THE H3. I TALKED TO GM SAFETY AND THEY WON'T DO ANYTHING AND BOUT IT BECAUSE IT'S OUT OF WARRANTY DUE TO AGE AND MILES. THERE IS NO REASON FOR THIS NOT TO BE A RECALL ISSUE. NO BLOWER MOTOR MEANS NO DEFROST ON YOUR WINDSHIELD. DUE TO COLD WINTERS IN NEW YORK YOU NEED THE DEFROST. NOW MY TRUCKS BLOWER MOTOR WORKS WHEN IT WANTS TO DUE TO FAULTY WIRE HARNESS IN TRUCK. I HAVE PICTURES OF THE PLUG AND OLD RESISTER. THANK YOU *TR
