IT APPEARS THAT THE FRACTURES OF H2 STEERING KNUCKLES CAN BE ATTRIBUTED TO WHEEL/TIRE COLLISION FORCES BEING TRANSFERRED DIRECTLY TO THE STEERING KNUCKLE.THE ORIGINAL KNUCKLE DESIGN APPEARS TO BE SUFFICIENT FOR THE H2 APPLICATION.EVIDENCE FROM INSPECTED VEHICLES, PHOTOGRAPHS, POLICE REPORTS AND EDR DATA INDICATES COLLISION IMPACT EVENTS PLACED STRESS ON THE STEERING KNUCKLE CAUSING IT TO FRACTURE.FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS WITH REGARD TO THE SUBJECT COMPONENT.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION ON THIS ISSUE IF WARRANTED.

DURING THE PE, ODI INVESTIGATED THE HUMMER H2 FOR FRACTURES WHICH WERE OCCURRING AT THE FRONT STEERING KNUCKLE LOWER BOSS.WHEN THE KNUCKLE LOWER BOSS FRACTURES, THE LOWER BALL JOINT STUD IS RELEASED AND THE ENTIRE KNUCKLE AND WHEEL/TIRE ASSEMBLY SEPARATES FROM THE VEHICLE.ODI IS UPGRADING THIS INVESTIGATION TO GAIN A FULL TECHNICAL UNDERSTANDING OF THE FACTORS WHICH CONTRIBUTED TO THESE FAILURES.

While driving in extreme rain downfall at night my windshield wipers stopped functioning. I could not see the road. Luckily I had just exited the highway when this happened. Therefore I was able to move over to the side of the road turn on my hazards and wait an hour for the rain to settle before driving to a near by gas station. Otherwise a fatality would have been likely being on a busy interstate should the wipers failed to function then. That wipers do not work and the Hummer can not be driven when rain is expected. I heard a recall had been issued for wiper malfunction. However when pulling up any recalls from my vin nothing shows but I have seen recalls for this situation and for the same make model and year. Please advise. I have given the vehicle to my 16 year old son a soon to be new driver and is excited to start but I must get this safety isssue taken care of first.

THE PASS LOCK KEEPS MY VEHICLE FROM STARTING AND STOPPING IT AT RANDOM, AND HAS BEEN DOING THIS FOR YEARS. SEEMS TO HAPPEN TO AT LEAST 85% OF HUMMERS OUT THERE IF YOU CHECK AROUND, HUMMER FORUM AND OTHER PLACES. THIS IS VERY SERIOUS. STOPS AT INTERSECTIONS, AND COULD ON RAILROAD TRACKS. I KNOW THAT YOU'VE HAD COMPLAINTS ABOUT THIS FOR YEARS AND IGNORED THEM, SAYING THAT YOU HAVEN'T HAD OTHER COMPLAINTS. THIS SHOULD BE ADDRESSED BY YOUR AGENCY, AS YOUR JOB IS TO KEEP THE CITIZENS SAFE. NOT PASS THEM OFF AS YOU'VE BEEN DOING FOR YEARS ON THIS ISSUE WITH THE GM PASS LOCK SYSTEM. THIS NEEDS RECALLED BEFORE MORE PEOPLE ARE KILLED DUE TO THIS MISS FUNCTION ON HUMMERS. MORE PEOPLE ARE HAVING THIS SHUTDOWN ISSUE THAN NOT. WHEN IT HAPPENS, YOU HAVE TO WAIT BETWEEN 10 AND 30 MINUTES WITH THE KEY IN THE START POSITION BEFORE IT WILL START. SO IT SITS IN THE MIDDLE OF AN INTERSECTION, INTERSTATE, BRIDGE, OR ANYWHERE ELSE DURING THIS TIME. HOPEFULLY YOU WILL ADDRESS THIS ISSUE PROMPTLY.

ONE EVENING WHILE DRIVING IN THE RAIN ON A LOCAL ROAD HEADED HOME MY WINDSHIELD WIPERS WHICH OFCOURSE WERE IN OPERATION SUDDENLY STOPPED STUCK IN THE UPRIGHT POSITION I IMMEDIATELY HEARD A SOMEWHAT LOUD HUMMING NOISE SOUNDING AS IF IT WERE COMING FROM INSIDE THE UPPER DASHBOARD I COULDN'T SEE TO DRIVE AS I NATURALLY RESPONDED TO THE WIPERS SUDDENLY STOPPING AND IN THE UPWARD POSITION MAKING IT HARD FOR ME TO SEE WHILE DRIVING, I QUICKLY TURNED THE KNOB ON THE LEFT SIDE OF THE STEERING WHEEL WHICH OPERATES THE WIPERS SPEED AND ON & OFF FUNCTION IN HOPES IT WOULD BRING THE WIPERS DOWN TO THE RESTING POSITION ESPECIALLY IF TURNED OFF HOWEVER EVEN THOUGH I TURNED THE KNOB TO THE OFF POSITION THE WIPERS REMAINED FROZEN IN THE SAME UPWARD STATE AS WHEN NO LONGER WIPING BUT THE HUMMING NOISE STOPPED. I QUICKLY PULLED OFF THE ROAD TURNING THE WIPERS ON AGAIN I COULD HERE THE HUMMING NOISE BUT THE WINDSHIELD WIPERS STILL FAILED TO MOVE. WHEN I TURN THE WIPERS OFF AGAIN NO NOISE COULD BE HEARD AND YET STILL NOT MAKING A DIFFERENCE IN MOVING THE WIPERS WHICH STOPPED WORKING WHILE IN THE UP ON WINDSHIELD POSITION. AFTER TOGGLING AROUND WITH THE ON AND OFF KNOB AND THE NOISE COMING ON AND OFF IN SEQUENCE WITH BUT NOT THE WIPERS I CONCLUDED THAT THE MOTOR WAS THE NOISE I WAS HEARING ESTABLISHING IT STILL WORKS HOWEVER NOT MOVING THE WIPERS IT IS INTENDED FOR. A WORKING WINDSHIELD WIPER MOTOR OR WHATEVER OPERATING MECHANISM BUT NO FUNCTIONAL WIPERS. THEREFORE I CAN NOT SEE ANYTIME DRIVING AND ALONG COMES THE RAIN FOR IT QUICKLY IMPAIRS THE VISIBILITY TO SEE THROUGH THE WINDSHIELD TO SEE THE ROAD OR TRAFFIC IN FRONT OF YOU MAKING EXTREMELY UNSAFE TO DRIVE AND PUTTING OTHER DRIVERS AT RISK ESPECIALLY IF ON THE HIGHWAY DOING FAST SPEEDS AND/ OR A PLACE WHERE IT IS NOT EASY TO PULL OVER SUDDENLY MAKES VERY STRESSFUL AND INCONVENIENT
