THIS IS THE 3RD TIME IN THE 5YRS I HAVE OWNED THIS VEHICLE THAT WE HAVE LOST CONTROL OF THE FRONT WINDSHIELD WIPERS DURING A RAIN STORM IN FLORIDA. WE HAVE REPLACED AT OUR EXPENSE THE WIPER CONTROL MODULE. THIS TIME BEING THE SHORTEST SPAN OF ABOUT A MONTH BEFORE IT GETS DAMP AND MALFUNCTIONS. WIPERS EITHER WORK INTERMITTENT OR NOT AT ALL AND THIS HAMPERS VISIBILITY AND CAN CAUSE A WRECK. I HAVE NOTICED THAT GM HAD A RECALL FOR 2003 BUT NOT FOR OTHER YEARS. I ALSO AM A MEMBER OF THE HUMMER FORUM AND CAN TELL YOU THAT THIS IS COMMON AMONGST ALL YEARS. *TR

DRIVING HOME I BEGAN TO SMELL AND ELECTRICAL BURNING SMELL. IT BEGAN VERY QUICKLY AND CAME AND WENT FOR ABOUT 2 MILES. I PULLED OVER AND LOOKED AND COULD NOT SEE SMOKE OR FIRE SO I CONTINUED HOME. I DROVE THE REMAINING 4 MILES TO MY HOME AND IMMEDIATELY GOT MY HUSBAND TO CHECK AS THE CAB HAD FILLED WITH THE SMELL OF AN ELECTRICAL FIRE. HE LOCATED THE AREA THE SMELL WAS STRONGEST AND THEN WATCHED AS SMOKE CAME OUT. HE UNBOLTED THE WINDSHIELD WASHER FLUID TANK AND THE MOTOR ON BOTTOM HAD ACTUALLY BURNED, MELTED AND WAS ON THE VERGE OF CAUSING SOME SERIOUS DAMAGE. THE WIPERS WERE NOT BEING USED AND HAD NOT BEEN TOUCHED. THIS VEHICLE IS EQUIPPED WITH A HEATER FOR THE FLUID. *TR

205V163000 · Seat Belts:rear/other
Apr 22, 2005
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.
05V043000 · Service Brakes, Hydraulic
Feb 8, 2005
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.
