HUMMER Complaints

THE SECURITY LOCK SYSTEM ON MY HUMMER H3 INTERMITTENTLY FLASHES DURING START CAUSING THE VEHICLE TO NOT CRANK. NORMALLY I HAVE TO WAIT 10 TO 20 MINUTES FOR THE SYSTEM TO RESET ITSELF AND SHE STARTS RIGHT UP, BUT TODAY IT'S BEEN 8 HOURS. FINALLY I HAD TO CALL FOR A TOW TO THE GM DEALERSHIP. WE GOT LUCKY TODAY. AT 10AM MY WIFE THOUGHT SHE WAS GOING INTO LABOR, WE GET TO THE TRUCK AND NO START. JUST A FLASHING SECURITY LOCK SYMBOL FLASHING AT ME. ENDED UP USING HER CAR. THIS IS DEFINITELY A SAFETY CONCERN, WHAT IF HER WATER HAD BROKE OR MY SON WAS NEEDING MEDICAL ATTENTION. I KNOW GM KNOWS OF THIS DEFECT BECAUSE I HAVE READ THOUSANDS OF COMPLAINTS ABOUT THIS EXACT PROBLEM ONLINE. THEY WILL NOT FIX IT UNLESS MADE TO.

TL* THE CONTACT OWNS A 2006 HUMMER H3. THE CONTACT STATED THAT THE BRAKE PEDAL WAS DEPRESSED, BUT THE BRAKE LIGHTS FAILED TO ILLUMINATE. THE CONTACT ALSO STATED THAT THE FRONT AND REAR TURN SIGNALS FAILED TO ILLUMINATE. THE FAILURE RECURRED MULTIPLE TIMES. THE VEHICLE WAS TAKEN TO A DEALER FOR DIAGNOSTIC TESTING. THE MECHANIC STATED THAT THE CONTROL MODULE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 140,000.

I HAVE OWNED MY HUMMER H3 FOR APPROXIMATELY 8 YEARS AND DURING THE LAST 4 TO 5 YEARS I HAVE EXPERIENCED A REPETITIVE ISSUE WITH THE VEHICLE NOT STARTING AND THEN AFTER WAITING 10 MINUTES AND IT STARTS WITH NO ISSUES. THIS OF COURSE HAS BEEN HAPPENING MORE FREQUENTLY NOW, BECOMING MORE AND MORE OF AN ANNOYANCE/INCONVENIENCE. I HAVE COMMUNICATED THIS TO GM AND THEIR ANSWER IS THAT IT IS NOT A RECALL AND THEY SOUND SOMEWHAT SURPRISED WITH THE ISSUE AS IF THEY ARE HEARING IT FOR THE FIRST TIME. I HAVE GONE ONLINE AND HAVE WITNESSED THE NUMEROUS COMPLAINTS FROM OTHER HUMMER CUSTOMERS. SOME HAVE SPENT THOUSANDS OF DOLLARS TO ACHIEVE TEMPORARY OR NO RESOLUTION TO THIS PROBLEM. I AM HOPING THAT MY TESTIMONY TO THIS ISSUE WILL FURTHER CORROBORATE/JUSTIFY OTHER COMPLAINS ALREADY FILED FOR THE SAME PROBLEM AND INFLUENCE A CORRECTIVE ACTION RESPONSE "RECALL" FROM GM.

TL* THE CONTACT OWNS A 2008 HUMMER H3. WHEN THE VEHICLE WAS TAKEN TO BE SERVICED FOR NHTSA CAMPAIGN NUMBER: 15V421000 (VISIBILITY), THE TECHNICIAN DISCOVERED THAT TWO BOLTS LOCATED ON THE EXHAUST MANIFOLD WERE FRACTURED. AS A RESULT, CARBON MONOXIDE WAS LEAKING INSIDE THE VEHICLE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 54,000.

THE VEHICLE WAS PURCHASED USED @ 36954 MILES. APPROXIMATELY A YEAR LATER (JUST 2 DAYS AGO) @ ONLY 53500 MILES I NOTICED AN ANTIFREEZE SMELL. NO VISIBLE PUDDLE UNDERNEATH. AFTER MONITORING FOR 1 DAY MORE POPPED THE HOOD THIS MORNING AND A BIT OF ANTIFREEZE SEEMS TO BE SPRAYING FROM THE TOP OF THE RADIATOR. AFTER JUST GOOGLING ONCE FOR "HUMMER H3 RADIATOR LEAK" THE TOP LINK LEADS TO HUMMERFORUMS.COM IN WHICH IS LOGGED MANY MANY MANY OWNERS GOING BACK SEVERAL YEARS UP THE THE PRESENT HAVING THE EXACT SAME ISSUE. PER WHAT IS DESCRIBED ON THE 52 PAGES DEDICATED TO THIS ONE THREAD AND FROM WHAT I SEE ON MY OWN VEHICLE THIS CERTAINLY SEEMS TO BE A DESIGN/ENGINEERING FLAW. IT SEEMS A RARE FEW DEALERSHIPS ARE OWNING UP TO THIS "FLAW" AND CHARGING A SMALL AMOUNT IF ANY TO REPAIR THIS ISSUE WHILE OTHERS ARE PLEADING IGNORANCE/INNOCENCE AND MAKING THE PLETHORA OF CUSTOMERS EAT THE NEARLY $800 DEALERSHIP REPAIR ESTIMATE. THE FLAW APPEARS TO BE RELATED TO METAL CHASSIS PARTS RUBBING ON THE PLASTIC RADIATOR TOP CREATING A HOLE AND A VIBRATORY EFFECT WEAKENING THAT PLASTIC CAUSING A CRACK.

TL* THE CONTACT OWNS A 2003 HUMMER H2. WHILE DRIVING APPROXIMATELY 15 MPH, THE TRACTION CONTROL AND ABS WARNING INDICATORS ILLUMINATED. THE FAILURE RECURRED WHENEVER DRIVING OVER 15 MPH. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED, BUT NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE ISSUE. THE APPROXIMATE FAILURE MILEAGE WAS 116,500.

THE VEHICLE JUST LOST POWER AND ALMOST LOST IGNITION WHILE DRIVING 50 MILES AN HOUR. DIAGNOSTIC CODE STATE, MISFIRE IN CYLINDER ONE. VALVE SPRINGS ( ROCKER ARM) ARE BREAKING PREMATURELY CAUSING A LEAKING VALVE PROBLEM. MECHANIC ALSO NOTICED OTHER SPRINGS WERE FATIQUED CAUSING A LOOSER THAN NORMAL SEATING. GM SERVICE MANAGER MENTION A SPRING PROBLEM ON 2006 2007 RENDEVOUS. ONE OF THE LARGEST COMPLAINTS WITH THE HUMMER 3 IS THIS LEAKY VALVE SYNDROM WHICH THE DEALERS KNOW ABOUT. SOME OCCURING WITH THE VEHICLE HAVING ONLY 30,000 PLUS MILES.

THERE ARE TWO ISSUES WITH THIS VEHICLE WHICH IS ALSO VERY PREVALENT IN THE FORUMS: 1. PASSLOCK SENSOR FAILURE - THIS PREVENTS THE CAR FROM STARTING FOR 10 MINUTES. MANY HAVE DESCRIBED SAFETY DUE TO STRANDING IN UNSAFE LOCATIONS AND IN EXTREME WEATHER SITUATIONS. 2. RADIATOR CRACKING - THE DEALER ACKNOWLEDGES THIS IS A COMMON PROBLEM.
