The pass lock in this vehicle is faulty. On numerous occasions, it has left me unable to start the vehicle, but if you wait 10 minutes each time, it will start again, but it happens all the time. I've seen numerous complaints online and GM needs to do something about it.
The last dealership I went to they advised to come th the dealership but when I got there nobody wasn’t trying to work there instead the said that it was going to be hard to work on it cause nobody work on those cars anymore and then they said they were going to order the part but never call me back for it. Call them but gave me the runaround basically.

SECURITY SYSTEM STOPS IT FROM CRANKING AND I HAVE TO STAND OUTSIDE THE VEHICLE WITH IT LOCKED FOR 15 MINUTES SO IT WILL RESET. WIRING BURNT UP AND I HAD IT REPLACED AND THE RADIO, A/C, AND TEMP GAUGE STILL DOESN'T WORK
WHEN ATTEMPTING TO START THE VEHICLE, IT LOCKS ME OUT FOR 10 MIN, I HAD IT HAPPEN TWO TIMES IN A ROW WHERE I COULDN'T START IT FOR 20 MINUTES AND WAS LATE FOR WORK. I HAVE BEEN SUCK IN -20 DEGREE WEATHER WITH MY CHILD. THIS IS AN ON GOING ISSUE, AND THERE ISN'T AN ERROR CODE THAT POPS UP WHEN I HAD IT CHECKED. THIS NEEDS TO BE FIXED!! THERE IS NO WAY TO TELL WHEN IT IS GOING TO HAPPEN, THEREFORE IT HAS MADE IT VERY UNRELIABLE AND HAS PUT ME AND MY FAMILY AT RISK.
IT SEEMS THAT THE H3, AND QUITE A FEW OTHER GM CARS OF THIS ERA, HAS A FUEL CUTOFF SWITCH ENABLED BY A SECURITY SYSTEM WHICH READS THE CAR'S KEY. HOWEVER, IT ALSO HAS A HUGE HISTORY OF FAILING TO OPERATE EVEN WHEN THE PROPER KEY IS USED BY THE CAR'S OWNER. THIS REPRESENTS A DANGEROUS FLAW IN THE DESIGN OF THESE CARS, NOT IN THE SENSE THAT IT CAREEN OFF THE ROAD WITHOUT WARNING OR THE LIKE, BUT THAT IT'S ALREADY STRANDED MY WIFE MULTIPLE TIMES IN DANGEROUS CIRCUMSTANCES. THE FIX IS CURRENTLY TO REPLACE, AT A COST OF $300 PLUS, THE IGNITION SWITCH WITH EXACTLY THE SAME PART THAT'S FAILED, WHICH IS TO SAY THAT IT'S MORE THAN LIKELY TO FAIL AGAIN, AS NOTHING HAS BEEN DONE TO RE-ENGINEER THE FAILED SYSTEM. I BELIEVE THAT GM NEEDS TO REALLY FIX THE PROBLEM, RATHER THAN SHRUG THIS OFF AS AN INCONVENIENCE, ESPECIALLY WHEN THEY ARE NOT ONLY APPRISED OF THE PROBLEM (MANY, MANY OWNERS HAVE EXPERIENCED THIS), THEY ARE PLANNING TO RE-INTRODUCE THE BRAND WITH AN ELECTRIC DRIVE TRAIN. THE REPORTING PAGE REQUESTS A SPECIFIC DATE, BUT TODAY IS ONE OF MANY TIMES THIS HAS HAPPENED.
TL* THE CONTACT OWNS A 2008 HUMMER H3. THE CONTACT RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBER: 15V421000 (VISIBILITY). THE CONTACT STATED THAT THE AIR CONDITIONING MODULE FAILED AND THE AIR BAG WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO RIZZA CADILLAC BUICK GMC (LOCATED AT 8425 159TH ST, TINLEY PARK, IL 60487, (708) 429-6600), WHERE IT WAS DIAGNOSED AND REPAIRED. THE DIAGNOSTIC AND REPAIR SPECIFICS WERE NOT DISCLOSED. THE FAILURES RECURRED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS UNKNOWN.
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!
STARTER SWITCH MOUNTED ON THE LOCK CYLINDER ASSEMBLY SHORTS OUT AND ENABLES THE PASS LOCK MODULE OR SECURITY AND YOU HAVE WAIT TEN MINUTES TO START THE VEHICLE
MY HUMMER WAS PARKED IN MY GARAGE AND WOULD NOT START. THERE WAS A CLICKING NOISE WHEN I TURNED THE KEY. I CALLED AAA THINKING IT WAS A DEAD BATTERY. THEY CAME OUT, GOT IN THE CAR AND IT STARTED RIGHT UP. THEY TESTED ALL ELECTRICAL AND FOUND NO ISSUES. THE BATTERY IS LESS THAN 2 YEARS OLD. A FEW WEEKS LATER, I DROVE A SHORT DISTANCE, PARKED AND TURNED OFF MY HUMMER. LESS THAN 1 MINUTE LATER, I GOT IN AND IT WOULD NOT START. THIS TIME, NO CLICKING NOISE, NOTHING. I WAITED A FEW MINUTES, SINCE I REMEMBERED THAT IT STARTED UP THE LAST TIME THIS HAPPENED. A FEW TRIES AND ABOUT 10 MINUTES LATER, THE HUMMER STARTED. I IMMEDIATELY DROVE IT TO MY MECHANIC FOR A COMPLETE DIAGNOSTIC CHECK-COST $110.00. EVERYTHING CHECKED OUT FINE, AND THEY COULD NOT REPLICATE THE PROBLEM. I HAVE LOOKED ONLINE AND FOUND HUNDREDS OF COMPLAINTS FROM PEOPLE WITH THE SAME EXACT PROBLEM. AND THERE SEEMS TO BE NO FIX. GM REFUSES TO DO ANYTHING ABOUT IT. I HAVE HAD AN ISSUE ALMOST FROM DAY ONE WITH THE KEY FOB SETTING OFF THE ALARM WHEN I TRY TO UNLOCK THE VEHICLE. THE HORN BLOWS, BUT NOT STRONGLY LIKE IT WOULD IF THE CAR IS BEING BROKEN INTO. IT'S A VERY WEAK HONK, AND IT WILL NOT STOP UNTIL THE DOOR IS UNLOCKED AND THE KEY INSERTED INTO THE IGNITION AND THE VEHICLE IS STARTED. MY DEALER SAID THERE WAS NOTHING THEY COULD DO ABOUT THIS AND SUGGESTED IT MIGHT BE THE FOB BATTERY. IT'S NOT, IT DOES IT WITH NEW BATTERIES INSTALLED. THE CONSENSUS OF READERS ONLINE IS THAT THIS NOT STARTING ISSUE IS A FLAW IN THE ANTI-THEFT SYSTEM. THE VEHICLE THINKS IT'S BEING STOLEN AND THEREFORE WILL NOT START. I ALSO BELIEVE THIS IS THE CASE, BASED ON THE PROBLEMS I'VE HAD WITH THE KEY FOB. GETTING STUCK SOMEPLACE IS NOT ONLY ANNOYING, BUT CAN BE DANGEROUS. I LIVE IN ARIZONA WITH TEMPS IN EXCESS OF 110 DURING THE SUMMER. LIKEWISE FOR PEOPLE THIS HAPPENS TO IN AREAS OF FRIGID COLD AND SNOW.
IT STARTED ONE MORNING I WENT TO START MY VEHICLE AND IT WOULDN'T START I WAS GETTING A (NO CRANK NO START).I TESTED THE BATTERY THAT HAD BEEN REPLACED ONLY MONTHS BEFORE AND THE BATTERY WAS FINE, I THEN PROCEEDED TO CHECK MY IGNITION AND STARTER FUSES AND RELAYS ALL WERE REPLACED. I NOTICED I HAD A DASH LIGHT ON THAT WAS A CAR SYMBOL NOT EVER DEALING WITH IT I TALKED TO A GARAGE AND WAS TOLD IT WAS THE ANTI THEFT PASS LOCK SYSTEM AND THAT I COULD CHECK BY LETTING THE KEY ON FOR 10 MINS THEN WHEN THE LIGHT GOES OUT START IT WORKED AS THEY SAID. THEY SUGGESTED I REPLACE THE LOCK ASSEMBLE WHICH INCLUDED THE LOCK HOUSING,KEY CYLINDER,AND PASS LOCK MODULE.I GOT THE PARTS FROM MY LOCAL DEALER AND HAD THEM REPLACED AND RE LEARNED CAR WORKED FINE NO LIGHT ANY MORE FOR ABOUT 4 MONTHS. AT THAT TIME I WAS DRIVING WITH MY FAMILY DOWN THE HIGHWAY AND THE VEHICLE SHUT OFF DURING DRIVING I GOT IT TO THE SIDE OF THE ROAD AN IMMEDIATELY TURNED MY KEY OFF AND TRIED STARTING IT AGAIN WHEN I DID SO I NOTICED THAT STUPID RED DASH LIGHT SHAPED LIKE A CAR WAITED THE 10 MINS AS DID BEFORE AND STARTED RIGHT UP TOOK IT RIGHT HOME NOW THE SAME THING BUT IT JUST BLINKS AND WILL NOT GO OFF ANYMORE. THIS IS A VERY SERIOUS PROBLEM NOT STARTING SOMEWHERE IS ONE THING THAT'S BAD ENOUGH BUT TO HAVE IT SHUT OFF COMPLETELY WHEN DRIVING IS SCARY. I HAVE MAINTAINED THIS VEHICLE REGULARLY AND I'M FINDING OUT THAT THEIR ARE MULTIPLY PEOPLE HAVING THE SAME ISSUE WITH THEIR VEHICLES NOT ONLY HUMMER'S BUT MOST GM PRODUCTS. *TR
I HAVE BEEN HAVING SECURITY ISSUES WITH THIS VEHICLE FOR THE LAST 2 YEARS. KEEPS ME STRANDED AT TIMES UNTIL THE SYSTEM RESETS ITSELF. MY HOOD IS RATTLING AND AM AFRAID ONE DAY IT WILL COME OFF. DON'T WANT TO TRADE IT IN BUT MAY NOT HAVE A CHOICE. IF COMPANIES ARE AWARE OF THESE PROBLEMS THEY NEED TO FIX THEM BEFORE SOMEONE GETS KILLED OR SERIOUSLY INJURED. IT IS A TOTAL SHAME THAT CONSUMERS HAVE TO DEAL WITH ALL THESE PROBLEMS AND BY THE WAY PAYING HIGH CAR OR TRUCK NOTES A MONTH AND HAVING TO DEAL WITH EXTRA PROBLEMS WE DON'T NEED OR WANT. FIX EVERYTHING RIGHT THE FIRST TIME AND THERE WON'T BE SO MANY COMPLAINTS COMING YOUR WAY. I HAVE TAKEN MY VEHICLE IN MORE THAN ONCE FOR RECALLS ON THIS VEHICLE. PLEASE DO SOMETHING ABOUT THESE PROBLEMS BEFORE SOMEONE GETS SUED. THANK YOU FOR YOUR TIME. *TR

THE VEHICLE WAS TAKEN TO A DEALER WHO STATED THAT MORE TIME WAS NEEDED TO DIAGNOSE THE FAILURE. THE CONTACT DID NOT WANT TO PAY THE DIAGNOSTIC FEE WITHOUT CHECKING TO SEE IF THE VEHICLE WAS INCLUDED IN A RECALL. THE FAILURE RECURRED, BUT THE VEHICLE WAS NOT DIAGNOSED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND STATED THAT THERE WAS A RECALL. THE CONTACT STATED THAT NHTSA CAMPAIGN NUMBER: 15V421000 (VISIBILITY) DID NOT ADDRESS THE FAILURE.

INTERMITTENTLY THE VEHICLES PASSLOCK SECURITY SYSTEM DISABLES THE STARTER LEAVING THE DRIVER AND PASSENGERS STRANDED FOR 10 MINUTES WHILE THE SYSTEM RESETS ITSELF AND REENGAGES THE STARTER. THIS ISSUES SEEMS TO OCCUR AT RANDOM, I HAVE NOT BEEN ABLE TO DUPLICATE THE PROBLEM AT WILL. AN INTERNET SEARCH ON THE PASSLOCK SECURITY ISSUES PROVES THAT THIS IS A COMMON PROBLEM WITH THE H3.
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 2008 HUMMER H3. WHILE DRIVING APPROXIMATELY 50 MPH WITH THE AIR CONDITIONING UNIT ACTIVATED, THERE WAS A BURNING ODOR INSIDE THE VEHICLE WITHOUT WARNING. THE AIR CONDITIONER FAILED. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE LOWER RESISTOR AND WIRING HARNESS FAILED, MELTED TOGETHER, AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE CONTACT RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBER: 15V421000 (VISIBILITY), HOWEVER, THE PART TO DO THE REPAIR WAS UNAVAILABLE. THE CONTACT STATED THAT THE MANUFACTURER EXCEEDED A REASONABLE AMOUNT OF TIME FOR THE RECALL REPAIR. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 82,926. VIN TOOL CONFIRMS PARTS NOT AVAILABLE.
THE AIR CONDITIONING BEGAN WORKING INTERMITTENTLY TWO YEARS AGO. ABOUT A YEAR AGO IT STOPPED COMPLETELY. THE ISSUE IS RELATED TO OVERHEATING OR MELTING OF AN ELECTRICAL COMPONENT (OURS HAS MELTED AND IS VISIBLE) AND I RECEIVED A RECALL NOTICE OVER A MONTH AGO BUT THE PART IS STILL UNAVAILABLE TO DO THE REPAIR. I LIVE IN FLORIDA WHERE THE TEMPERATURES ARE HIGH MOST OF THE YEAR SO I HAVE BEEN DEPRIVED OF FULL USE OF MY VEHICLE FOR ALMOST TWO YEARS. I BELIEVE GM NEEDS TO DO BETTER TO GET THESE ISSUES RESOLVED AS OUR LOSS OF USE IS NOT IN ANY OTHER MEANS BEING COMPENSATED. THIS IS FRUSTRATING AND DISAPPOINTING AND WE NEED IMMEDIATE RESOLUTION. IT IS A FREQUENT, KNOWN, RECURRING AND COSTLY ISSUE.
I OWN A 2008 HUMMER H3 AND FOR THE PAST 4 1/2 YEARS I HAVE BEEN DEALING WITH ISSUES RELATED TO ENGINE NOT STARTING WHEN YOU FIRST GET IN. IF YOU WAIT EXACTLY 10 MINUTES, IT STARTS JUST FINE. I HAVE HAD DEALERSHIPS AND REPAIR SHOPS LOOK AT THE VEHICLE AND NO ONE SEEMS TO KNOW EXACTLY WHAT IS CAUSING THIS INTERMITANT PROBLEM. THE COMPANY THAT INSTALLED MY ALARM SYSTEM THOUGHT IT COULD BE THE IGNITION AND/OR THE PASSLOCK. APPARENTLY, THE PASSLOCK IS WHAT THINKS YOUR CAR IS BEING STOLEN AND SHUTS IT DOWN FOR 10 MINUTES. HOWEVER, THEY ARE EACH $600 AND NO GUARANTEE THAT EITHER IS THE PROBLEM AND THE CAR IS OUT OF WARRANTY. AFTER READING SOME HUMMER FORUM THIS APPEARS TO BE A GLOBAL PROBLEM WITH ALL HUMMERS FROM 2006 TO 2010 AND GM REFUSES TO ADMIT THEY HAVE A SERIOUS PROBLEM AND WILL NOT SUBMIT A RECALL FOR THE FAULTY IGNITION SWITCH.
