Yesterday I turned off the alarm and unlocked the doors via the keypad. I opened the driver door and my wife opened the passenger rear door and the Hummer H2 started. No key in the ignition and the fob does not have a start button. I then got in the car and inserted the key and turned the key to ON then to off and the vehicle would not shut off. Only after cycling through the gears was I able to shut off the vehicle. I have now disconnected the battery to prevent another unwanted start.

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 DRIVING HOME AT NIGHT AND ABOUT A MILE BEFORE I GOT HOME MY TRANSMISSION DIDN'T SEEM TO SHIFT AS SMOOTH AS IT USUALLY DOES AND WHEN I PARKED IN MY GARAGE I GOT OUT AND TRANSMISSION FLUID WAS DRIPPING OUT FROM UNDER MY H2 VERY QUICKLY AND BY THE NEXT HOUR IT HAD EVERY BIT RUN OUT AND HUGE PUDDLE OF TRANSMISSION FLUID WAS ALL OVER MY GARAGE FLOOR. I TOOK THE SKID PLATE OFF MY H2 AND THE TRANSMISSION LINE HAD A HOLE RUSTED THROUGH IT. HAD I BEEN ANOTHER FEW MILES AWAY FROM GETTING HOME THIS COULD HAVE DESTROYED MY TRANSMISSION AND POSSIBLY CAUSED ME TO WRECK.

I CHECKED UNDER THE HOOD AND SAW THAT THE BRAKE FLUID RESERVOIR WAS COMPLETELY EMPTY. *TR

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
I FEEL THAT THIS KEY PROBLEM FALLING OUT OF THE IGNITION, KEY WILL NOT TURN ON OR OFF MAKING IT HARD TO CONTROL WHEN THE KEY IS IN THE IGNITION AND CAUSING IT NOT TO START. I HAD THIS SAME PROBLEM ON A 2003 ISUZU ASCENDER. ALSO THE "DRIVER INFORMATION CENTER" HAS QUIT WORKING RIGHT WHICH CONTROLS A LOT OF THINGS ON THE VEHICLE. I THINK IT IS A DEFECTIVE SWITCH FROM GM WHO ALSO BUILT MY 2003 ISUZU. *TR
