FRONT WHEEL LINKAGE FAILURE, WHEEL FELL OFF. MY BROTHER AND I NEARLY DIED TODAY FROM AN ACCIDENT IN MY MOTHERS H2. WE HAD JUST LEFT A FRIENDS HOUSE AND WERE TRAVELING AT ABOUT 35 MPH WHEN ALL OF A SUDDEN IT SEEMED THAT THE FRONT DRIVER SIDE WHEEL BROKE FREE. THE H2 VIOLENTLY SWERVED TO THE LEFT AND EVEN THOUGH I AM A BIG GUY IT WAS ALMOST IMPOSSIBLE TO KEEP THAT 6000 LBS BEAST FROM SWERVING. I HIT THE BRAKES BUT THOSE DIDN'T SEEM TO HELP SINCE THE BRAKES WERE STILL ATTACHED TO THE WHEEL WHICH I COULD SEE WAS BEHIND US FROM THE SIDE VIEW MIRROR…

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
