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.

TL* THE CONTACT OWNS A 2004 HUMMER H2. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 35 MPH, THE BRAKE PEDAL FAILED TO RESPOND WHEN DEPRESSED REPEATEDLY. THE VEHICLE WAS DRIVEN UPHILL IN COMBINATION OF THE EMERGENCY BRAKE BEING ENGAGED IN AN ATTEMPT TO STOP THE VEHICLE. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC WHERE THE BRAKE POWER BOOSTER WAS REPLACED. IN ADDITION, THE MASTER CYLINDER AND BRAKE LINES WERE REPLACED AT DIFFERENT TIMES. THE MANUFACTURER WAS NOTIFIED OF THE DEFECT. THE APPROXIMATE FAILURE MILEAGE WAS 71,000.
ON CERTAIN CREW CAB PICKUP TRUCKS AND SPORT UTILITY VEHICLES, THE 2ND ROW CENTER OCCUPANT SEAT BELT ROUTING MAY MAKE IT DIFFICULT TO POSITION THE LAP PORTION OF THE SAFETY BELT LOW AROUND THE HIPS OF OCCUPANTS, ESPECIALLY SMALLER OCCUPANTS, SEATED IN THIS POSITION. APPROPRIATE USE OF A CHILD SEAT OR BOOSTER SEAT, AS RECOMMENDED FOR SMALL CHILDREN, DOES IMPROVE THE FIT CONDITION FOR THIS USER GROUP. IN ADDITION TO INSTRUCTIONS ON PROPER INFANT AND YOUNG CHILD RESTRAINT (WITH CHILD SEATS OR BOOSTERS), SPECIAL VERBIAGE FOR RESTRAINING OLDER CHILD IS INCLUDED IN THE OWNER'S MANUAL. ALSO, THE SUGGESTED SEAT BELT FIT/ROUTING FOR ADULTS, IRRESPECTIVE OF SEATING POSITION, IS DESCRIBED IN THE OWNER'S MANUAL TEXT.
Consequence & remedy
Consequence: A LAP PORTION OF THE SEAT BELT ROUTING THAT IS NOT LOW AND SNUG ON THE HIPS CAN ALLOW THE LAP BELT TO RIDE UP ON AN OCCUPANT'S ABDOMEN INSTEAD OF FITTING LOW AROUND THEIR HIPBONES, AND THEREFORE, CAN EXPOSE THEM TO MORE RISK OF ABDOMINAL AND INTERNAL ORGAN INJURY.
Remedy: DEALERS WILL CUT OPEN THE GUIDE LOOP, REMOVE A PORTION OF THE LOOP, AND THEN THE REMAINING TWO SIDES SHOULD BE FOLDED OVER AND SECURED WITH A RETAINER FREE OF CHARGE. THE RECALL BEGAN ON JULY 21, 2005. OWNERS MAY CONTACT CADILLAC AT 1-866-982-2339, CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, OR HUMMER AT 1-800-732-5493.
CERTAIN TRUCKS, SPORT UTILITY VEHICLES, AND VANS EQUIPPED WITH BOSCH HYDRO-BOOST BRAKE ASSEMBLIES, THE HYDRAULIC BRAKE BOOSTER PRESSURE ACCUMULATOR MAY CRACK AND SEPARATE FROM THE HYDRO-BOOST ASSEMBLY DURING NORMAL OPERATING CONDITIONS.
Consequence & remedy
Consequence: IF A SEPARATION OCCURRED AND THE HOOD OF THE VEHICLE WERE OPEN, FRAGMENTS FROM THE ACCUMULATOR COULD CAUSE INJURY TO PEOPLE IN THE IMMEDIATE AREA. THE PRESENCE OF THIS CRACK OR FRACTURED SURFACE COULD ALLOW THE HYDRAULIC FLUID TO LEAK FROM THE ACCUMULATOR CIRCUIT OF THE BOOSTER ASSEMBLY. THE LOSS OF FLUID WOULD CAUSE INCREASED STEERING AND BRAKING EFFORT AND A CRASH MAY OCCUR WITHOUT PRIOR WARNING.
Remedy: DEALERS WILL TEST THE HYDRO-BOOST ASSEMBLY FOR FUNCTIONAL OPERATION OF THE TWO-FUNCTION VALVE. IF THE HYDRO-BOOST ASSEMBLY FAILS THE TEST, DEALERS WILL REPLACE THE ASSEMBLY FREE OF CHARGE. THE RECALL BEGAN ON MARCH 23, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC TRUCKS AT 1-866-996-9463 AND HUMMER AT 1-800-732-5493.
CERTAIN SPORT UTILITY VEHICLES, PICKUP TRUCKS, AND PASSENGER VANS FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 135, ?PASSENGER CAR BRAKE SYSTEMS.? SOME OF THESE VEHICLES WERE PRODUCED WITH AN OUT-OF-SPECIFICATION BRAKE HYDRO-BOOST HOUSING RELIEF VALVE BORE.
Consequence & remedy
Consequence: CONSEQUENTLY, THE VALVE O-RING SEAL MAY FRACTURE. STEERING EFFORTS MAY BE SLIGHTLY INCREASED WHILE BRAKING OR PARKING. UNDER CERTAIN DRIVING CONDITIONS, A FRACTURED SEAL MAY REQUIRE A SLIGHT INCREASE IN THE APPLIED BRAKE PEDAL EFFORT TO ACHIEVE THE SAME VEHICLE DECELERATION RATE AS PRIOR TO THE SEAT FRACTURE.
Remedy: DEALERS ARE TO REPLACE THE HYDRO-BOOST RELIEF VALVE. THE RECALL BEGAN ON JUNE 18, 2004. OWNERS SHOULD CONTACT CADILLAC AT 1-866-982-2339; CHEVROLET AT 1-800-630-2438; GMC AT 1-866-996-9463; OR HUMMER AT 1-866-486-6376.

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.
