2007 HUMMER H3 Engine And Engine Cooling Problems

NOTICED RADIATOR FLUID DRIPPING UNDERNEATH VEHICLE. OPENED THE HOOD AND FOUND RADIATOR COOLANT HAD BEEN BLOWN ALL OVER INTERIOR ENGINE COMPARTMENT. ENOUGH COOLANT REMAINED IN THE RESERVOIR TO PREVENT OVERHEATING. I NOTICED THE INCIDENT JUST IN TIME. *TR

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

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...

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

RADIATOR IS CRACKED ON DRIVER SIDE DUE TO RUBBING OF METAL PARTS. *TR

TL* THE CONTACT OWNS A 2007 HUMMER H3. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 20 MPH, THE ENGINE STALLED WITHOUT WARNING AND RESTARTED. THE FAILURE OCCURRED FOUR TIMES. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER FOR DIAGNOSIS AND THEY WERE UNABLE TO DUPLICATE OR DETERMINE THE CAUSE OF FAILURE. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 70,000.

EVER SINCE I PURCHASED THIS VEHICLE, THE VEHICLE HAS STALLED AT BETWEEN 25MPH AND 0. I WORK FOR THE US CENSUS BUREAU, PERMANENT WORKER AND I TRAVEL THROUGH ALL TYPES OF WEATHER CONDITIONS IN A DAY, FROM 9,000 FT MOUNTAINS COVERED IN SNOW TO DESERT GRAVEL ROADS, MESAS, CLIFFS. OVER THE PAST TWO YEARS THE VEHICLE HAS SHUT OFF WHILE TRAVERSING MOUNTAIN ROADS COVERED IN SNOW WITH NO GUARD RAILS, AND THREE TIMES, WHEN THE ENGINE SHUT OFF, I LOST STEERING AND CAME WITHIN INCHES OF GOING OFF THE SIDE (CLIFFS) OF THESE ROADS, NOT TO MENTION IN TOWN, WHEN MY ENGINE SHUTS OFF AS I DRIVE, I HAVE COME CLOSE TO HITTING OTHER VEHICLES OR POLES AS I LOSE POWER STEERING ON A TURN.. I HAVE TO DRIVE ABOUT 90 MILES ONE WAY TO GET IT SERVICED, WHILE UNDER WARRANTY, I HAD IT "REPAIRED" ABOUT FIVE TIMES, NO SUCCESS,...

2007 HUMMER H3 HAS VIBRATION IN THE BRAKE AND ACCELERATOR PEDAL. THE CONSUMER ALSO STATED THE VEHICLE OVERHEATED WHILE DRIVING IN TRAFFIC. *JB THE CONSUMER STATED SHE CONTINUES TO FEEL A KICK IN THE PEDAL. THE DEALER WAS UNABLE TO FIX THE PROBLEMS ON THE VEHICLE. UPDATED 01/18/11. *JB

I HAD DROPPED MY DAUGHTER OFF AT SCHOOL THEN WENT TO THE GAS STATION AND I SMELLED SOMETHING LIKE IT WAS BURNING AND I THOUGHT IT WAS OUT SIDE. WHEN I CAME OUT OF THE GAS STATION THERE WAS SMOKE ROLLING OUT OF MY HUMMER . I HAD JUMPED IN AND MOVED THE VEHICLE AWAY FROM THE PUMPS SO THEY WOULD NOT BLOW UP AND HURT THE PATRONS AROUND US. THE FIRE DEPT CAME AND SO DID THE POLICE. THEY TOLD ME THAT THE BLOW HAD STARTED FROM BEHIND THE GLOVE COMPARTMENT AND WAS ON FIRE. *TR
