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

AIR BLOWER FOR AIR CONDITIONING AND HEATER STOPPED WORKING BECAUSE MELTED PLASTIC ON RESISTOR ALSO FRIED WIRING AND HARNESS NEEDED TO BE REPLACED. *TR

MY SON WAS DRIVING HIS 2007 HUMMER H3 WHEN IT CAUGHT ON FIRE. IT WAS AN ELECTRICAL FIRE STARTED ON THE PASSENGER SIDE IN THE DASH. HE DIDN'T KNOW IT WAS ON FIRE UNTIL HE GOT OUT OF THE CAR TO GO INTO A RESTAURANT. HE DIDN'T EVEN SMELL ANYTHING BURNING AND HAD ONLY BEEN DRIVING AROUND 5 MINUTES. PEOPLE WERE POINTING AT HIS CAR TELLING HIM IT WAS ON FIRE. THE LOCAL FIRE DEPARTMENT GOT TO HIM IN 3-4 MINUTES. THE HUMMER H3 WAS TOTALED OUT BECAUSE OF THE FIRE. THE CAR HAD APPROXIMATELY 64,000 MILES ON IT AND WAS IN EXCELLENT CONDITION. *TR

JUST HAD MY HUMMER IN 2 WEEKS AGO AT THE GM DEALERSHIP TO HAVE THE IGNITION SWITCH REPLACED. HAD BEEN DEALING WITH IT STRANDING ME AND MY KIDS FOR 10 MINUTE PERIODS LONG ENOUGH. ( SOMETIMES LONGER) WHILE IT WAS IN THERE WE ALSO HAD TO GET THE RADIATOR REPLACED DUE TO IT BEING CRACKED. NOW 2 WEEKS LATER MY CHECK ENGINE LIGHT AND TRACTION LIGHT HAVE COME ON. THE TRACTION LIGHT SAYING SERVICE SAB SYSTEM. AFTER READING ALL THE HUMMER PROBLEMS I CAN NOT BELIEVE THAT THERE WAS NOT A RECALL ON BOTH THE IGNITION SWITCH AND RADIATOR. THE IGNITION SWITCH BEING FAULTY PUT ME AND MY KIDS IN SITUATIONS IN PLACES FOR LONG PERIODS OF TIME THAT WERE NOT SAFE AND AT TIMES WE WERE VERY COLD SINCE WE CAN HAVE BELOW ZERO WEATHER IN COLORADO. THE IGNITION NOT RECOGNIZING THE KEY CAUSING THE ANTI THEFT SYSTEM TO ACTIVATE IS RECALL ISSUE AND GM YOU SHOULD BE TAKING RESPONSIBILITY FOR THIS!! *TR

THE CAR SHUT OFF AS I WAS MAKING A LEFT HAND TURN WITH NO WARNING OR INDICATION. COMPLETE LOSS OF POWER. *TR

TL* THE CONTACT OWNS A 2007 HUMMER H3. THE CONTACT STATED THAT WHENEVER THE AIR CONDITIONER OR HEATER WAS TURN ON, BURNING WIRE FUMES WOULD EMIT INTO THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER. THE TECHNICIAN DIAGNOSED THAT RESISTOR NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED BUT THE FAILURE RECURRED. THE VEHICLE WAS TAKEN BACK TO THE DEALER WHO REPLACED THE BLOWER AND THE WIRE HARNESS THAT HAD MELTED. THE FAILURE RECURRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE ISSUE. THE APPROXIMATE FAILURE MILEAGE WAS 40,000.

CONTINUOUS PROBLEMS WITH VEHICLE SHUTTING DOWN AND OR NOT STARTING WITH FAULTY PASSLOCK II SYSTEM..... ........ OWNERS MANUAL SAYS TO WAIT 10-15 MIN BUT KEEPS HAPPENING INTERMITTENTLY 4 TIMES ON 9-9-14 PROBLEM IS WORSENING BY THE WEEK. *TR

THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 119,000.

MY VEHICLE HAS A CRACKED RADIATOR AND ACCORDING TO OTHER HUMMER OWNERS THIS IS A COMMON DEFECT THAT HAPPENS TO THESE VEHICLES. HIS OVER HEATING CUASED ME TO PULL OVER ON A BUSY HIGHWAY WERE I COULD OF BEEN HIT AND KILLED, TOTAL FAILER OF VEHICLE ELECTRONICS, GMC DOES NOT WANT TO WORK ON THE VEHICLE THAT IS NOT UNDER WARRANTY, BECAUSE OF THE MANY PROBLEMS WTH THIS VEHICLE. THIS CRACK IS WERE IT IS WEARING NEAR THE MOTOR. *TR

WAS DRIVING IN A SMALL TOWN AND THE VEHICLE JUST LOST ALL POWER WITH NO WARNING. IT COST ME OVER 600.00 TO GET REPAIRED AND I'M THANKFUL I WAS NOT ON THE HIGHWAY GOING 60 OR 70 AND I'M THANKFUL THERE WAS NO VEHICLES BEHIND ME. ALSO THE KEY WON'T COME OUT OF THE IGNITION AFTER I DRIVE IT FOR A WHILE AND THIS WEARS DOWN MY BATTERY AND I HAVE TO GET A JUMP. HAS THERE BEEN ANY RECALLS OR OTHER COMPLAINTS ABOUT THESE PROBLEMS. *TR

I PURCHASED THIS VEHICLE, NEW IN JULY 2007. SINCE THAT TIME I HAVE METICULOUSLY MAINTAINED THE VEHICLE. ON 7/28/14, PARKED AT HOME. GOT OUT AND SMELLED COOLANT VAPORIZING (DISTINCT SMELL). I AM A RETIRED MASTER MECHANIC, WITH 44 YEARS EXPERIENCE (CURRENTLY AGE 60). I EXAMINED THE RADIATOR, RINSED IT OFF AND DRIED IT, PRESSURIZED THE SYSTEM TO DISCOVER A HAIRLINE CRACK IN THE UPPER, PLASTIC TANK OF THE RADIATOR IN AN AREA WITH NO IMPINGEMENT OF OTHER COMPONENTS, NO TRAUMA, AND NO ROUGH USE, EVER. I CAUGHT IT AT THE VERY FIRST MANIFESTATION, SOLELY BY THE SMELL. EXAMINING THE VEHICLE CLOSELY TO DISCOVER WHILE MY RADIATOR HAD ONLY THIS HAIRLINE CRACK IN A LOCATION OF NO-STRESS AND NO IMPINGEMENT OF OTHER COMPONENTS. RESEARCH FURTHER TO DISCOVER THIS IS A VERY COMMON PROBLEM WITH THE H3, FROM 2006, 2007, 2008 AND 2009 MODELS ALL IN THE 50,000 TO 100,000 MILE READINGS. THE REPLACEMENT OF THE RADIATOR AT LOCAL GM DEALER, WITH COOLING SYSTEM SERVICE WAS EXTREMELY EXPENSIVE AS THE REPLACEMENT OF THE RADIATOR REQUIRES THE RECEIVER DRYER OF THE AIR CONDITIONING SYSTEM TO BE DISCONNECTED WHICH REQUIRES DISCHARGE AND RECHARGE OF REFRIGERANT R124A. I SAVED THE DEFECTIVE RADIATOR. THERE IS NO OTHER WEAR NOR DAMAGE. THE INTERNAL CORES WERE CLEAR AND CLEAN LIKE NEW. NO OBSTRUCTIONS, DIRT NOR WEAR. IN OTHER WORDS I WAS FORCED TO REPLACE A PERFECTLY GOOD RADIATOR FOR 1 HAIRLINE CRACK ON THE UPPER PLASTIC TANK. THIS REPAIR, INCLUDING ALL COURTESY DISCOUNTS FROM THE SELLING DEALERSHIP, AS I HAD

I WAS DRIVING HOME I WAS GOING ABOUT 50 MPH WHEN I HEARD A LOUD NOISE. MY SIDE CURTAIN AIRBAGS AUTOMATICALLY DEPLOYED. MY SEAT BELT LOCKED UP ON ME AND CAUTION LIGHT CAME ON. I PULLED OFF THE ROAD TO SEE WHAT HAPPENED. I WAS GLAD THAT NO CAR WAS AROUND BECAUSE I WOULD HAVE WRECKED. THE INSIDE OFT HUMMER WAS FILLED UP WITH GUN POWDER. I CALLED GM AND TOLD THEM WHAT HAPPENED. AFTER ABOUT 2 DAYS OF CALLING THEY CAME TO PICK UP MY TRUCK. THEY FIRST ASKED ME IF I COULD DRIVE IT TO THE LOCAL DEALER 25 MILES AWAY LOL NO MY AIRBAGS ARE DOWN AND I COULD NOT PUT MY SEAT BELT ON. SO NOW I HAVE A RENTAL CAR TO DRIVE TILL THEY LET ME KNOW SOMETHING. I JUST SO GLAD THAT IT DID NOT HAPPEN THE DAY BEFORE WHEN I WAS DRIVING DOWN 95 I COULD HAVE BEEN DIED IF IT WOULD HAVE GONE OFF THEN. I HOPE GM WILL FIX THE PROBLEM. *TR

FAN BLOWER RESISTOR BURNT UP AND MELTED WIRING HARNESS ELECTRICAL SEAT BUTTON THAT CONTROLS POSITION AND HEAT TURNS ON DUE TO THE SIDE PLASTIC SEAT MOLDING THAT FLEXES WHEN YOU SIT IN THE SEAT. *TR

WIPERS STOP INTERMITTENTLY AND DO NOT RETURN TO PARK POSITION. WIPERS COME ON WHEN STARTING VEHICLE AND THE SWITCH MUST BE TURNED ON AND OFF TO MANUALLY STOP THEM IN THE PROPER PARK POSITION. THIS IS A SERIOUS ISSUE THAT HAS COMPLAINTS ALL OVER THE INTERNET AND HAS PEOPLE QUESTIONING THE VIABILITY OF A CLASS ACTION SUIT. *TR

AC/HEAT BLOWER FAN RESISTOR FAULTY. CAUSES BLOWER TO STOP WORKING. THE SHORT MAY CAUSE A FIRE. MANY COMPLAINTS OF THIS ISSUE ON THE INTERNET. MAY BE TIME TO PURSUE A CLASS ACTION SUIT. *TR

HUMMER H3 HAS PASSLOCK SECURITY PROBLEM WHEN DRIVING. WHEN I DRIVE THE HUMMER AT ANY SPEED MY HUMMER LOCKS OUT AND ACTIVATES THE SECURITY LOCK AND LOOSES POWER FOR 10 SECONDS AND GAINS POWER AGAIN OR LOOSES POWER COMPLETELY FORCING ME TO PULL OVER AND TURN MY CAR BACK ON. *TR

RADIATOR HAD SMALL LEAK, HAS SINCE INCREASED OVER LAST 3 YEARS. NOT COVERED UNDER WARRANTY AND EVERY H3 OWNER KNOWS THIS IS A DEFECT THAT NEEDS TO BE RECALLED. *TR

LESS THAN 1 YEAR AGO, I HAD THE RADIATOR AND TRANSMISSION REPLACED IN MY VEHICLE. I HAVE RECENTLY NOTICED THE SMELL OF ANTIFREEZE COMING FROM MY HOOD AFTER LONG TRIPS. THE RADIATOR THAT WAS INSTALLED IN MY VEHICLE 10 MONTHS AND 8K MILES AGO HAS DEVELOPED A CRACK IN THE TOP TANK. THERE IS DRIED COOLANT SPRAY ACROSS THE TOP OF MY ENGINE AND A CRACK FORMING RIGHT BEHIND THE LIP OF THE FRAME OF THE TRUCK. *JS

MY RADIATOR TANK CRACKED RIGHT ACROSS THE TOP COMPROMISING MY COOLING SYSTEM. THIS TURNED INTO A BIGGER PROBLEM AS THE TRANSMISSION OIL COOLER WAS NOT OPERATING CORRECTLY AND EVENTUALLY DESTROYING MY TRANSMISSION. I HAD TO SPEND OVER $2K TO HAVE A REFURBISHED TRANNY AND NEW RADIATOR INSTALLED. *JS

44,000 MILES CHECK ENGINE LIGHT CAME ON . TOOK TO DEALER I HAD A CYLINDER 5 MISFIRE CODE P300 COUPLE THOUSAND MILES LATER MY TRUCK WAS STILL SHOWING MULTIPLE MISFIRES. I HAD TO REPLACE THE RADIATOR BECAUSE IT WAS LEAKING AND THERMOSTAT AT 46,000, APRIL 2011 AT 65,000MILES MY TRANSMISSION WENT OUT COMPLETELY AND HAD TO BE REPLACED JULY 2012 AIR STOP WORKING TOOK TO DEALER THEY SAID I HAD TO REPLACE THE FAN BLOWER MOTOR RESISTOR. RESEARCHED AND FOUNDED THIS WAS A KNOWN PROBLEM FOR HUMMERS THE MOTOR GETS TO HOT AND MELT CAUSING THE FAN BLOWER TO GO OUT . SEVERAL MONTHS LATER CHECK ENGINE LIGHT CAME ON SEVERAL MORE TIMES TOOK TO THE DEALER SAID THEY COULDN'T FIND PROBLEM AND CLEARED CODE MY CHECK ENGINE LIGHT CAME ON AGAIN SO I TOOK TO AUTO ZONE DIAGNOSTIC SHOWED CYLINDER 5 COIL MULTIPLE MISFIRE SO I HAD SPARK PLUGS CHANGED ALONE WITH ALL FIVE IGNITION COILS. COUPLE MONTHS LATER CHECK ENGINE LIGHT CAME ON AGAIN TOOK IT TO DEALER DIAGNOSTIC TEST REVEAL CODE PO 300 AGAIN AND COUPLE OTHER CODES DEALER SAID MY TRUCK HAD AN EMISSION LEAK. MULTIPLE MISFIRE ,CYLINDER 5 AND A SMALL CRACK IN THE HEAD. I DIDN'T UNDERSTAND HOW THAT MAGICALLY HAPPEN. I PAID THE DEALER TO FIX THIS ON MARCH 2014. A WEEK LATER CHECK ENGINE LIGHT CAME ON AGAIN . TOOK TO DEALER DIAGNOSTIC SHOWED EMISSION LEAK APPARENTLY THEY DIDN'T FIX IT THE FIRST TIME. WEEK LATER CHECK ENGINE LIGHT CAME ON AGAIN TOOK TO DEALER AND DIAGNOSTIC TEST REVEAL TORQUE CONVERTER CLUTCH SOLENOID .DEALER SAID I NEED TRANSMISSION REPLACED.

I OWN A 2007 HUMMER H3 WITH 66000 MILES ON IT. IT HAS BEEN DIAGNOSED AS HAVING A BAD HEAD DUE TO THE USE OF SOFT METALS FOR THE CYLINDER SLEEVE. DUE TO THIS, THERE IS SUDDEN REDUCED POWER. THE COST OF THIS FIX IS ABOUT $4500.00. MY TRUCK BEGAN WITH A CHECK ENGINE LIGHT ON (AUTOZONE) SAID IT WAS A MISFIRE ON CYLINDER #5. I WENT TO THE LOCAL DEALER AND ASKED THEM TO LOOK AT THE TRUCK. THEY DIAGNOSED IT AS A #5 CYLINDER HAVING THE COMPRESSION LEAK OF 90%. IN LOOKING ON THE INTERNET (AT HUMMER FORUMS), I OBSERVED THAT QUITE A FEW HUMMER H3 OWNERS WERE WRITING IN ABOUT THEIR EXPERIENCE WITH MISFIRES AND BAD HEADS, AT ABOUT THE SAME MILEAGE. I THINK THIS NEEDS TO BE LOOKED INTO AND THAT GM SHOULD BE ORDERED TO DO A RECALL. THIS IS THE SAME PROBLEM THEY HAD WITH THE 3.5L ENGINES THEY USED IN THEIR PRE-2007 HUMMER H3 AND COLORADO. I AM GOING TO WRITE MY CONGRESS REP AND ASK THAT WITH THE PROBLEMS THAT GM IS HAVING RIGHT NOW, THAT THIS ALSO BE MOVED FORWARD AND THAT THEY ORDER AN INVESTIGATION. ANY OTHER HUMMER H3 OWNERS WITH THE SAME PROBLEMS SHOULD DO THE SAME THING. *TR

MY CAR BEGAN SHOW THE PASSLOCK DISABLING SYSTEM LIGHT AND THEN FAILING TO START. AFTER STARTING, IT WOULD THEN SHOW THE AIR BAG WARNING LIGHTS FOR A PERIOD THAT MIGHT BE SEVERAL MINUTES TO SEVERAL DAYS BEFORE GOING OUT AGAIN. THIS CYCLE HAPPENED AT RANDOM TIMES DISABLING THE AUTO WITHOUT WARNING AND IN SOME DANGEROUS SITUATIONS. IT IS A WELL KNOWN AND PUBLICIZED PROBLEM THAT GM HAS CHOSEN TO IGNORE. I HAVE SOLVED THE PROBLEM BY HAVING PASSLOCK DISABLED AND IGNORING THE AIR BAG WARNING LIGHT WITH THE ASSUMPTION IT IS A FALSE WARNING. THESE RECENT EVENTS HAVE ME RECONSIDERING THAT ACTION, BUT THE COST OF HAVING THE PROBLEM RECTIFIED WOULD BE MORE THAN I COULD AFFORD. *TR

I WAS SITTING IN THE LINE AT MY SON'S SCHOOL, BEEN SITTING THERE 2 - 3 MINUTES, AND I SMELLED COOLANT. LOOKED AT MY GAUGE AND IT WAS RIDING JUST BELOW MID-POINT....NORMAL. GOT MY SON AND STARTED HOME. SITTING AT THE RED LIGHT, I SMELLED COOLANT AGAIN. THIS TIME I KNEW IT WAS MY CAR. WE WENT TO A SERVICE STATION AND ASK IF SOMEONE COULD CHECK TO SEE IF WE HAD A LEAK. THEY PULLED MY H3 INTO THE BACK AND HOOKED UP A PRESSURE "TOOL" TO THE RADIATOR AND LOW AND BEHOLD, BUT A HAIRLINE CRACK ON THE UPPER DRIVER'S SIDE OF THE RADIATOR. THE MECHANIC LAUGHED AND SAID I WAS THE 2ND ONE THIS WEEK AND THE 6TH ONE SINCE THEY OPENED 6 MONTHS AGO. HE SAID THAT H3S WERE KNOWN TO HAVE RADIATOR ISSUES BECAUSE THE RADIATORS WERE PLASTIC! SERIOUSLY...PLASTIC! I WAS GIVEN A QUOTE OF $1,100 TO REPLACE THE RADIATOR WITH ANOTHER PLASTIC ONE AND THAT WOULD GIVE ME A 2 YEAR OR 24,000 MILE WARRANTY. I BROUGHT THE TRUCK BACK TO MY HOUSE SO MY HUSBAND COULD LOOK AT IT. I DID SOME RESEARCH ON THE INTERNET AND IT SEEMS THAT THIS IS A WELL KNOWN PROBLEM WITH HUMMERS AND YET GM HAS NOT DONE A RECALL. I FOUND A NUMBER FOR HUMMER CUSTOMER SERVICE AND CALLED THEM. WHEN I TOLD THE MAN THAT ANSWERED I HAD COOLANT LEAKING, HE SAID "OH, GIVE ME YOUR ZIP CODE AND I WILL FIND A LOCAL DEALERSHIP THAT CAN REPLACE THE RADIATOR." NO QUESTIONS...HE KNEW WHAT THE PROBLEM WAS ALREADY. HE WENT ON TO SAY THAT WE WOULD HAVE TO "INVEST" IN A DIAGNOSTIC AND IF THE DEALERSHIP DETERMINED IT WAS A MANUFACTURERS DEFECT, THAT HUMMER M

SMELLED RADIATOR FLUENT WHEN I PARKED INTO THE DRIVE WAY, POPPED THE HOOD AND SAW THAT THE LIQUID SPLASHED ALL OVER THE ENGINE AND PARTS AS WELL AS ON TOP OF THE PLASTIC FAN COVER, WHICH SEEMED ODD. COULDN'T FIND THE LEAK IN THE HOSE. LOOKED AT THE HUMMER FORUM THAT I'M A MEMBER OF AND LORD BEHOLD THERE WAS A BIG TOPIC OF RADIATORS CRACKING AND BREAKING IN THE SAME PLACES WITH THE 2007 MODELS. NO RECALL HAS BEEN ISSUED, SO NO RECALL HAS BEEN SUBMITTED. BUT IT'S A WELL KNOWN DEFECTIVE RADIATOR PROBLEM THAT GM KNOWS ABOUT BUT WON'T RECALL. SO THEY DECIDED TO MAKE A NEW RADIATOR THAT FIXES THE PROBLEM FOR THE 2007 HUMMERS. THE PROBLEM IS THE MIDDLE PIN THAT HOLDS THE RADIATOR RUBS THE NECK AND STARTS A CRACKED UNDER THE STYROFOAM, THUS THE RIGHT DRIVERS SIDE CRACKS IN THE SAME SPOT AS WELL ON THE PLASTIC SIDE. HUNDREDS OF H3 OWNERS HAD THIS HAPPEN TO THEM AND POST PICS AND WHAT NOT, BUT STILL NO RECALL. THIS PROBLEM IS ONGOING AND NOTHING IS BEING DONE. I HAVE SPOKE TO THE HUMMER CUSTOMER SERVICE AND THEY CONTACTED THE LOCAL GM AND THEY SCHEDULED MY SCHEDULED DATE TO TAKE MY H3 IN FEB 17 2014, @ 8 AM AT THE LOCAL GM DEALERSHIP AND HOPEFULLY THEY WILL FIX THIS ISSUE AND NOT CHARGED ME TO FIX DUE TO THE FACT THAT THEY KNOW THE PROBLEM AND HAVE DONE NOTHING TO FIX IT. BUT IT'S BEEN KNOW THAT THEY WILL NOT FIX THE RADIATOR AND THEY SAY IT'S DUE TO CLIMATE WHICH IS FALSE BECAUSE EVERY H3 OWNER HAS IT BREAK IN THE SAME PLACE, AND HAVE SUBMITTED COUNTLESS TICKETS. *TR

TL* THE CONTACT OWNS A 2007 HUMMER H3. THE CONTACT STATED THAT WHILE DRIVING 25 MPH, SHE BEGAN TO SMELL PLASTIC BURNING UNDER THE DASHBOARD. THE CONTACT STATED THAT WHEN SHE STOPPED THE VEHICLE, SHE NOTICED THAT THE RESISTOR FOR THE MOTOR BLOWER HAD CAUGHT ON FIRE AND MELTED. THE VEHICLE WAS NOT TAKEN TO THE DEALER FOR INSPECTION. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 120,000.

I WAS DRIVING ON THE EXPRESS WAY WHEN I NOTICED MY ENGINE REV REAL HIGH. I LOOKED AT THE RPM'S AND IT WAS ALMOST RED LINED. I LET OFF THE GAS IMEDIATLY AND CAME TO A SLOW CRAWL AND FOUND THAT IT WOULD NOT SHIFT OUT OF SECOND GEAR. PULLED IT OFF THE ROAD AND SHUT IT OFF TO GET OUT TO FIND THAT THERE WAS TRANSMISSION FLUID AND RADIATOR COOLANT POURING FROM THE TRANSMISSION. HAD IT TOWED TO A MECHANIC TO FIND OUT THAT THE RADIATOR WAS BAD WHICH CAUSED THE TRANSMISSION AND COOLANT TO MIX BETWEEN THE TWO. THIS CAUSING THE TRANSMISSION TO BE DESTROYED ALONG WITH THE RADIATOR. FOR THIS VEHICAL BEING THIS LOW ON MILES THIS SHOULD HAVE NEVER HAPPEND. GM HAS MADE A FAULTY RADIATOR AND SOMETHING NEEDS TO BE DONE. *TR

HIT POTHOLE ON I-285 AS EXITING ONTO RAMP FOR I-20 EXIT. BUMP WAS NOT THAT SEVERE BUT APPARENTLY FAULTY ROLLOVER SENSOR TRIGGERED BOTH SIDE AIRBAG DEPLOYMENT . *TR

HAD PURCHASED VEHICLE 3 DAYS PRIOR FROM INDIVIDUAL. DROVE TO EL PASO TX1 APPROXIMATELY 80 MILES DROVE AROUND TOWN DOING ERRANDS. TRANSMISSION STARTED SLIPPING BADLY, I PULLED INTO A WAL-MART AND WENT TO CHECK THE TRANSMISSION FLUID. VEHICLE HAD A COMPRESSION TYPE DIPSTICK. WHEN I TOUCHED THE LEVER ON THE DIPSTICK IT SHOT UP APPROXIMATELY 8 INCHES AND SHOWERED MY RIGHT HAND WITH VERY HOT TRANSMISSION FLUID. THIS CAUSED SECOND DEGREE BURNS TO THE PALM AND FINGERS, THIS MADE A TRIP TO THE EMERGENCY ROOM NECESSARY. THE OWNER OF THE TRANSMISSION SHOP TOLD ME THAT IN HIS 20 YEARS IN THE BUSINESS HE HAD NEVER SEEN A TRANSMISSION GET SO HOT AS TO MELT THE FILTER. THIS ONE HAD MELTED THE FILTER. *TR

HERE ARE MULTIPLE ISSUES WELL DOCUMENTED ACROSS THE INTERNET OF HUMMERS HAVING AND ISSUE WITH THESE RESISTORS, AS WELL AS CHEVY COLORADOS. MY BLOWER QUIT A FEW MONTHS AGO, AND THE RESISTORS AND WIRING HARNESS ARE MELTED TO THE POINT OF CHARRING! THE NHTSA NEEDS TO INVESTIGATE THIS OR ARE YOU WAITING FOR AN ACTUAL FIRE TO CAUSE GM TO FIX THIS ISSUE? *TR

THE ANTI-THEFT PASSLOCK SYSTEM IS FAULTY AND WILL NOT LET ME START MY CAR. IT HAS HAPPENED TWICE SINCE I GOT THE CAR IN DECEMBER OF LAST YEAR. GOING ON-LINE TO SEE WHAT TO DO ABOUT IT MADE ME AWARE OF THE OVERWHELMING AMOUNT OF GM CAR OWNERS THAT THIS HAS AFFECTED. SOME BEING STRANDED FOR HOURS AND DAYS OF NOT BEING ABLE TO START THEIR CARS DUE TO THE FAULTY PASSLOCK SYSTEM. IT IS HAPPENING TO ALL MAKES AND MODELS OF GM CARS. I CALLED GM AND THEY WEREN'T INTERESTED IN DOING ANYTHING ABOUT THE PROBLEM UNLESS YOU FORCE THEM TO. PLEASE CHECK INTO THIS AND HELP THOSE OF US WHO GET STRANDED IN PLACES (SOMETIMES SCARY PLACES) BECAUSE OUR CAR WON'T START. THANK YOU. *TR

DRIVING DOWN THE ROAD AT 20 DEGREES OUTSIDE AND THE HEATER FAN QUIT. HAD CUT OUT A COUPLE TIMES BEFORE AND COME BACK ON. *TR

THIS VEHICLE HAS HAD TRANSMISSION ISSUES SINCE 25,000 MILES. NO CODE EVER INDICATED SO DEALERS WOULD NOT INVESTIGATE TRANSMISSION UNTIL 1ST AND 2ND GEARS FAILED. PROBLEM OF INCORRECT SHIFTING CONTINUED WITH SEVERAL STOPS AT THE DEALERSHIP. NO CODE NO SERVICE. NOW THE TRANSMISSION SLAMMED IN REVERSE INITIATING A CODE (SPEED SENSOR PASS/FAIL). AFTER AGREEING TO REPLACE THE PORTION OF THE TRANSMISSION THAT CONTAINS THE SHORTED SPEED SENSOR, IT WAS DISCOVERED THE TRANSMISSION WAS CONTAMINATED BY RADIATOR FLUID. NOW THE RADIATOR, NOT COVERED BY WARRANTY, ALSO MUST BE REPLACED WITH THE COMPLETE TRANSMISSION. RESEARCHING HUMMER FORUMS, THIS IS APPARENTLY A KNOWN ISSUE WITH THE SPEED SENSOR AND RADIATOR CONTAMINATION THAT IS BEING IGNORED. *TR

TL* THE CONTACT OWNS 2007 HUMMER H3. THE CONTACT STATED THAT THE IGNITION FAILED TO RECOGNIZED THE KEY, CAUSING THE ANTI-THEFT SYSTEM TO ACTIVATE. THE VEHICLE WAS TAKEN TO THE DEALER SEVERAL TIMES WHO WAS UNABLE TO DIAGNOSE THE FAILURE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE WHO DID NOT OFFER ANY ASSISTANCE. THE VEHICLE WAS NOT REPAIRED. THE VIN WAS NOT AVAILABLE. THE FAILURE MILEAGE WAS 40,000 AND THE CURRENT MILEAGE WAS 98,000.

I WAS IN A PARKING LOT, I STARTED THE VEHICLE AND TURNED THE AIR CONDITIONER ON. IT WORKED BUT SUDDENLY STOPPED BLOWING AIR. I TOOK IT IN AND IT WAS DIAGNOSED AS THE BLOWER MOTOR RESISTOR HAD GONE OUT. I HAD IT REPLACED ONLY TO HAVE THE SAME THING HAPPEN AGAIN ONE WEEK LATER BUT THIS TIME I SMELLED SOMETHING BURNING. THE WIRING HAD BURNED GOING TO THE RESISTOR. THE TECHNICIAN INFORMED ME THAT THIS HAPPENS OFTEN WITH THESE VEHICLES AND HE DOESN'T UNDERSTAND WHY THERE ISN'T A RECALL. AFTER RESEARCHING THE PROBLEM, I FOUND THAT THIS IS A COMMON AND POTENTIALLY VERY DANGEROUS PROBLEM WITH THE HUMMER H3. THERE NEEDS TO BE AN INVESTIGATION AND RECALL SO THAT NO ONE GETS HURT. IF I HAD A PASSENGER IN MY VEHICLE AT THE TIME OF THIS INCIDENT, THEY WOULD HAVE RECEIVED BURNS ON THEIR FEET FROM THE WIRING MALFUNCTION AND BURNING. I AGAIN AM HAVING TO PAY TO GET THIS CORRECTED. VIN # [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

I AM THE ORIGINAL OWNER OF A 2007 GENERAL MOTORS HUMMER H3. THE AUTO HAS BEEN WELL MAINTAINED AND PROFESSIONALLY SERVICED BY A GM DEALERSHIP. THE VEHICLE HAS 53,600 MILES AND IS IN PERFECT MECHANICAL CONDITION EXCEPT THIS RECENT ISSUE WITH PASSLOCK SECURITY WHICH HAS RENDERED THE VEHICLE UNRELIABLE AND A PERSONAL AND PUBLIC SAFETY HAZARD. THE VEHICLE IS LESS THAN 30 DAYS OUT OF WARRANTY AND DEALER WILL NOT REPAIR UNDER WARRANTY. IN RECENT WEEKS, THE PASSLOCK SECURITY LIGHT BEGAN RANDOMLY ILLUMINATING WHILE DRIVING. THIS LIGHT COULD EXTINGUISH ON NEXT START OR STAY ILLUMINATED THROUGH SEVERAL STARTS. TWO WEEKS AGO WHILE RETURNING FROM A TRIP LATER AT NIGHT, THE VEHICLE WAS DISABLED AND FAILED TO START IN AN AIRPORT PARKING LOT. THE PASSLOCK LIGHT CONTINUALLY FLASHED AND THE ENGINE CRANKED, BUT WITHOUT STARTING. A TOW TRUCK WAS CALLED, BUT BY THE TIME IT ARRIVED, AN ATTEMPT TO START THE VEHICLE WAS SUCCESSFUL AND THE LIGHT WAS EXTINGUISHED. THIS HAS HAPPENED AT LEAST TWICE SINCE IN LESS INCONVENIENT AND LESS DANGEROUS AREAS. THE VEHICLE IS UNRELIABLE AND UNSAFE. I CANNOT TRUST IT TO ALLOW MY WIFE TO DRIVE IT FOR FEAR IF HER BEING MAROONED IN A DANGEROUS SITUATION. THE DEALER HAS INDICATED IT MIGHT BE SEVERAL HUNDRED DOLLARS TO REPAIR THIS PROBLEM AND WAS WELL AWARE THAT IT WAS A WIDESPREAD PROBLEM WITH GM AUTOS. THERE ARE HUNDREDS OF SIMILAR COMPLAINTS ON THE INTERNET AND YET THERE IS NO RESPONSE OR ATTEMPT TO REMEDY THIS SITUATION BY THE MANUFACTURER. I AM A SENIOR CITIZEN AND
