ON AUG 23,07 AT APPROX 4:30 P.M., I PULLED UP TO A STOP SIGN IN SAN MATEO, CA. I STOPPED COMPLETELY, MADE A RIGHT HAND TURN, AND PROCEEDED SOUTH AT APPROX 10MPH, WHEN SUDDENLY THE RIGHT FRONT END OF MY 2003 HUMMER DROPPED ONTO THE GROUND, AND I COMPLETELY LOST CONTROL OF THE VEHICLE. THERE WAS NO STEERING, LITTLE BRAKE PEDAL AND THE VEHICLE PROCEEDED TO TRAVEL TO THE RIGHT AND COLLIDED WITH A PARKED VEHICLE. THERE WAS ABSOLUTELY NOTHING I COULD DO TO PREVENT THIS. I EXITED THE VEHICLE, A PEDESTRIAN APPROACHED ME, AND SAID HE NOTICED THE WHEEL WOBBLING AND SUDDENLY FLY OFF, TURN AROUND, MY VEHICLE DROP, SCREECH AND CONTINUE IN A FORWARD MOTION, AND THE WHEEL TURNED AROUND, CONTINUED MOVING, AND PARKED ITSELF IN A GREEN ZONE, INSIDE OUT, NEXT TO A CURB. I EXITED THE VEHICLE, SHOCKED AND CONFUSED, INSPECTED THE DAMAGED VEHICLE, INSPECTED THE AXLE ASSEMBLY AND WHEEL SITTING NEXT TO THE CURB, GOT MY WITNESS INFO, TOOK PICTURES AND NOTIFIED THE POLICE. I ALSO NOTIFIED MY INSURANCE (AAA). I ACQUIRED A RENTAL VEHICLE AND WAITED TO HEAR THE OUTCOME FROM MY INSURANCE CARRIER. THEY HAVE SINCE NOTIFIED ME THAT IT HAS BEEN DETERMINED THAT I AM 100 PERCENT AT FAULT FOR THIS COLLISION AND PRINCIPALLY AT FAULT FOR A ROLLAWAY VEHICLE. I HAVE ALSO CONTACTED GMC , WHO ARE ADMITTING NO LIABILITY, (GMC SAID A REP WILL RESPOND IN 30 TO 45 DAYS). I AM APPEALING AAA'S DETERMINATION THAT I AM AT FAULT, DUE TO THE FACT THAT THIS IS A STEERING KNUCKLE FAILURE (SAFETY), I COULD HAVE BEEN KILLED OR KILLED SOMEONE, THERE WAS NO REASONABLE WAY TO CONTROL AN OUT OF CONTROL VEHICLE, AND IF AAA AND/OR GMC DO NOT WANT TO STEP UP AND TAKE RESPONSIBILITY I WILL BE FORCED TO TAKE LEGAL ACTION. AS OF THIS LETTER, 36 DAYS LATER, I AM IN A RENTAL VEHICLE, MY VEHICLE HAS NOT BEEN TOUCHED, NO REPAIRS HAVE BEEN STARTED , AND EVEN IF THEY WERE, AT THIS POINT I DO NOT EVER WANT TO DRIVE THIS VEHICLE AGAIN. IT IS TOTALLY UNSAFE. IN ALL MY YEARS OF DRIVING, I HAVE NEVER BEEN SO SCARED OR SO OUT OF CONTROL. *TR

2003 HUMMER H2 SPEEDOMETER IS NOT ACCURATE OR CONSISTENT. CURRENTLY THE GAUGE IS STUCK ABOVE THE MAX SPEED ON THE GAUGE. EARLIER TODAY THE SPEEDO WENT DOWN TO 35 MPH WHILE THE VEHICLE WAS AT A STOP THEN CLICKED OR SURGERED ITS WAY PAST 120MPH WHILE DRIVING APPROX. 70MPH. THIS IS MADDENING AND UNSAFE. *TR

EA05017 · Hummer H2 Steering Knuckle Failures
Opened Oct 28, 2005 · Closed Apr 30, 2007
Status: closed (inferred from source dates) · Suspension:front:control Arm:lower Ball Joint
ODI UPGRADED THIS INVESTIGATION AT THE CONCLUSION OF PE04-080.THE ALLEGED DEFECT INVOLVES THE FAILURE OF THE STEERING KNUCKLE AT THE LOWER BALL JOINT BOSS, RESULTING IN A SEPARATION OF THE LOWER BALL JOINT FROM THE KNUCKLE.A LOWER BALL JOINT SEPARATION COULD RESULT IN A LOSS OF STEERING AND/OR A DISABLED VEHICLE. 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.
