AS I WAS DRIVING ON I 5 IN OREGON I EXPERIENCED A COMPLETE FAILURE OF THE ELECTRICAL SYSTEM AND BRAKE SYSTEMS. THE VEHICLE WAS ON CRUISE CONTROL AND WHEN I DISENGAGED IT ALL OF THE SAFETY WARNING LIGHT APPEARED ON THE DASHBOARD. I PRESSED ON THE BRAKES AND THEY WERE A COMPLETE FAILURE ALSO. AT THIS TIME THE DASHBOARD LIGHTS AND CONTROLS WENT OFF AND I LOSS POWER. I WAS ABLE TO GET TO THE SIDE OF THE ROAD WHEN I NOTICED SMOKE COMING FROM UNDER THE HOOD. I GOT MY DAUGHTER OUT OF THE VEHICLE TO A SAFE DISTANCE AND OPENED THE HOOD AND THE MAIN FUSE RELAY PANEL WAS FULLY ENGULFED IN FIRE. I CALLED 911. IN THE APPROX. 5 MIN. THE TIME THE FIRE TRUCK ARRIVED THE TRUCK WAS CONSUMED AND FULLY GUTTED OUT FROM THE FIRE.
MY 2004 H2 HAS A SERIOUS RUSTING ISSUE WITH THE BRAKE LINES. ON 2 SEPARATE OCCASIONS I HAVE BEEN DRIVING ALONG AT APPROXIMATELY 30 MPG AND HIT THE BRAKES ONLY TO HAVE THEM GO ALL THE WAY TO THE FLOOR. LUCKILY I DID NOT AN ACCIDENT. IN BOTH OCCASIONS THE LINE BURST DUE TO RUST. MY VEH. HAS 103,000.00 LIGHTLY DRIVEN. GM NEEDS TO COME OUT AND ADMIT THEY HAVE A PROBLEM WITH RUSTING BRAKE LIENS BEFORE SOMEONE GETS KILLED
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 WAS TRAVELING ON NJ TURNPIKE WHEN MY BRAKES DIDN'T FEEL RIGHT. ALMOST NO BRAKES STEPPING TO FLOOR. THEN BRAKE FAILURE LIGHT CAME ON. THIS IS A GARAGE KEPT VEHICLE WITH APPROX 14000 ORIGINAL MILES. APPEARS BRAKE LINES ARE CORRODED. ONE OWNER. HOW COULD THIS HAPPEN. IS THERE A RECALL HOW CAN I OBTAIN DETAILS FOR FULL RECOVERY OR REIMBURSEMENT? *TR

THE VEHICLE WAS DRIVEN UPHILL IN COMBINATION OF THE EMERGENCY BRAKE BEING ENGAGED IN AN ATTEMPT TO STOP THE VEHICLE.

EXTREMELY EXCESSIVE RUST ON UNDERBODY OF MY 2004 HUMMER H2. BRAKE LINES, CALIPERS, ROTORS, FRAME, SUSPENSION, ETC HAVE HOLES. MY BRAKES COMPLETELY FAILED ON THE HIGHWAY AND I CRASHED INTO A TRUCK AND A SUV. LUCKILY USED THE EMERGENCY BRAKE TO EVENTUALLY STOP IT. DEALER SAYS ENTIRE BRAKE SYSTEM NEEDS TO BE REPLACED AND THE FRAME IS ALSO IN BAD SHAPE. I DID REPORT THE RUST PROBLEM TO GM WHILE UNDER THE 3 YEAR WARRANTY BUT THEY DID NOTHING. I NEITHER DO ANY CROSS-COUNTRY DRIVING NOR AM NEAR THE OCEAN. I AM SCARED OF DRIVING THE VEHICLE. *TR
DISC BRAKE ROTORS NOT MACHINED TO LEGAL SPECIFICATIONS. APPROXIMATELY 40% OF ROTORS FACE WERE STILL ROUGH CASTING, THIS CAUSED ROUGH BRAKING AND EARLY BRAKE PAD FAILURE. DEALER AND GM REFUSED TO REPAIR UNDER WARRANTY, CLAIMED THEY WERE OK. I WILL NOT BUY ANOTHER GM PRODUCT FOR THEIR LACK OF CONCERN. STATE INSPECTION REQUIRES 100% CLEAN UP OF MACHINED SURFACE ON ROTORS. *TR
I WAS DRIVING MY 2004 H2 HUMMER. I WAS ON A DEEP SLOPE HILL. I WAS BACKING UP AND I HIT A 500 SERIES MERCEDEZ ON HIS LEFT BUMPER FROM LEFT REAR BUMPER. IMMEDIATELY AFTER I HIT, I STARTED TO SHIFT THE GEAR SO THAT I COULD STOP THE CAR TO GET OUT TO SEE WHAT HAPPENED. AT THIS POINT, THE HUMMER STARTED TO TRAVEL AT VERY FAST SPEED DOWN THE STREET IN THE SAME PATTERN THAT I HAD ORIGINALLY DRIVEN UP. I TRIED TO APPLY THE BRAKES, BRAKES DID NOT WORK. I TRIED TO STEER, STEERING WAS IN A LOCK POSITION. I HIT A PEDESTRIAN HARD AND MY CAR LANDED IN MY NEIGHBOR'S HOUSE. WHEN I HIT THE HOUSE, THE 2 FRONT WHEELS BECAME DETACHED FROM THE CAR. THE PEDESTRIAN THAT I HIT HAS INCURRED MANY SERIOUS DAMAGES. I HAD 1 ENGINEERING COMPANY LOOK AT THE CAR BACK IN 2004 AFTER THE ACCIDENT AND THEY SAID THEY COULD NOT FIND ANYTHING WRONG. WHEN I LOOK NOW, I'VE HEARD OF MANY CASES WHERE SIMILAR INCIDENTS HAVE OCCURRED DUE TO BRAKES. I AM CURRENTLY IN COURT FOR ANOTHER 1 WEEK AS THIS PEDESTRIAN IS NOW SUING ME. I PLEAD TO ALL H2 HUMMER OWNERS TO CONTRIBUTE ANY INFORMATION THAT THEY MAY HAVE ABOUT OTHER HUMMER OWNERS OR THEIR OWN EXPERIENCE. YOUR CONTRIBUTION TO THIS MATTER IS HIGHLY APPRECIATED. *TR
TL*THE CONTACT OWNS A 2004 HUMMER H2. WHILE DRIVING 55 MPH, THE HYDRAULIC SERVICE BRAKES BECAME STIFF AND MADE IT DIFFICULT TO STOP THE VEHICLE. THE CONTACT ALSO EXPERIENCED STEERING FAILURE, WHICH NEARLY CAUSED A CRASH. THE HUMMER MANUFACTURER STATED THAT HIS VIN WAS NOT INCLUDED IN NHTSA CAMPAIGN ID NUMBERS 05V043000, 04V045000 AND 06E010000. THE PURCHASE DATE WAS UNKNOWN.

DT: 2004 GMC HUMMER THE CONSUMER STATES HE HAD TO MAKE AN EMERGENCY STOP AND THE BRAKES WENT ALMOST TO THE FLOOR. THE VEHICLE WAS TAKEN TO THE DEALERSHIP AND THEY COULD NOT FIND ANYTHING WRONG WITH IT. THE CONSUMER TRIED TO DUPLICATE THE PROBLEM HIMSELF AND IT DID THE SAME THING AGAIN. HE FEELS IT WILL NOT STOP IN TIME DURING AN EMERGENCY. THE MANUFACTURER TOLD THE CONSUMER TO TAKE THE VEHICLE TO THE DEALERSHIP. THIS ALMOST CAUSED AN ACCIDENT. THE BRAKES FAIL EVERY TIME THE CONSUMER NEEDS TO MAKE AN EMERGENCY STOP. *NM
