CONSUMER COMPLAINED ABOUT A TRANSMISSION PROBLEM. WHEN DRIVING TRANSMISSION SOUNDED AND RODE ROUGHLY. CONSUMER TOOK THE VEHICLE TO DEALER ON THREE OCCASIONS . DEALER WAS UNABLE TO DETERMINE THE CAUSE OF FAILURE. MANUFACTURER WAS ALSO CONTACTED. *AK
CERTAIN VEHICLES ORIGINALLY BUILT WITH CLOTH SEATS THAT WERE EQUIPPED WITH AN AUTOMATIC AIR BAG PASSENGER SENSING SYSTEM AND LATER REUPHOLSTERED WITH AFTERMARKET LEATHER SEAT COVER KITS ARE INVOLVED. TESTING HAS INDICATED THAT THE AFTERMARKET LEATHER SEAT COVERS CAN CAUSE THE PASSENGER SENSING SYSTEM TO MALFUNCTION.
Consequence & remedy
Consequence: IF THE PASSENGER SENSING SYSTEM MALFUNCTIONS, THE FRONT AIR BAG ON THE PASSENGER SIDE MAY BE DISABLED WHEN IT SHOULD BE ENABLED, OR ENABLED WHEN IT SHOULD BE DISABLED. IN EITHER CASE, IN THE EVENT OF A CRASH THAT REQUIRES AIR BAG DEPLOYMENT, A FRONT PASSENGER'S LEVEL OF INJURY MAY BE INCREASED.
Remedy: BECAUSE A REPLACEMENT LEATHER SEAT COVER THAT IS COMPATIBLE WITH THE PASSENGER SENSING SYSTEM IS NOT AVAILABLE, GENERAL MOTORS (GM) WILL REPURCHASE THESE VEHICLES IN ACCORDANCE WITH THE TERMS STATED IN GM'S LETTER TO OWNERS. THE RECALL BEGAN ON NOVEMBER 6, 2006. OWNERS SHOULD CONTACT GM AT 1-877-477-1022 TO BEGIN THE PROCESS OF REPURCHASING THEIR VEHICLE.
ON CERTAIN TRUCKS EQUIPPED WITH AN 8.1L V8 (RPO L8-VIN G) ENGINE HAVE A CONDITION IN WHICH THE ENGINE FUEL RAIL PULSE DAMPER RETAINER CLIP MAY FRACTURE RESULTING IN INADEQUATE RETENTION OF THE DAMPER.
Consequence & remedy
Consequence: IF THE DAMPER COMES LOOSE, A FUEL LEAK MAY RESULT. FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE.
Remedy: DEALERS WILL REPLACE THE ENGINE FUEL RAIL PULSE DAMPER RETAINER CLIP FREE OF CHARGE. THE RECALL BEGAN ON AUGUST 31, 2006. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438 AND GMC TRUCKS AT 1-866-996-9463.
ON CERTAIN PICKUP TRUCKS EQUIPPED WITH MANUAL TRANSMISSIONS AND BUILT WITH EITHER PBR PARKING BRAKE SYSTEMS OR TRW PARKING BRAKE SYSTEMS, THE PARKING BRAKE FRICTION LININGS MAY WEAR TO AN EXTENT WHERE THE PARKING BRAKE CAN BECOME INEFFECTIVE IN IMMOBILIZING A PARKED VEHICLE.
Consequence & remedy
Consequence: IF THE PARKING BRAKE DOES NOT HOLD, UNINTENDED VEHICLE MOVEMENT COULD OCCUR, WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS WILL INSTALL A LOW-FORCE SPRING CLIP RETAINER FOR VEHICLES EQUIPPED WITH A PBR PARKING BRAKE SYSTEM. ON VEHICLES EQUIPPED WITH THE TRW PARKING BRAKE SYSTEM, DEALERS WILL INSTALL A REDESIGNED PARKING BRAKE CABLE ASSEMBLY. THE RECALL BEGAN ON JULY 29, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438 OR GMC AT 1-866-996-9463.
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 EXTENDED AND REGULAR CAB PICKUP TRUCKS AND CARGO VANS CONVERTED TO COMPRESSED NATURAL GAS (CNG) FAIL TO CONFORM TO THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 225, 'CHILD RESTRAINT ANCHORAGE SYSTEMS.' THESE VEHICLES HAVE ONE SEATING POSITION, THE CENTER REAR SEAT, EQUIPPED WITH CHILD RESTRAINT LOWER ANCHORAGES.
Consequence & remedy
Consequence: THE STANDARD REQUIRES CHILD SEAT LOWER ANCHORAGES IN TWO SEATING POSITIONS FOR VEHICLES WITH THREE REAR SEATING POSITIONS. THE STANDARD CAB AND CARGO VAN VEHICLES, WHICH ONLY HAVE FRONT SEATING POSITIONS, HAVE AN AIR BAG OFF SWITCH TO DISABLE THE FRONT PASSENGER AIR BAG AND DO NOT HAVE CHILD RESTRAINT LOWER ANCHORAGES IN THE PASSENGER SEAT. THE STANDARD REQUIRES PASSENGER SEAT CHILD SEAT LOWER ANCHORAGES IN VEHICLES WITH AN AIR BAG OFF SWITCH. HOWEVER, THE STANDARD DOES NOT REQUIRE VEHICLES WITH ONLY FRONT SEATING POSITIONS TO HAVE LOWER ANCHORAGE PROVISIONS IF THE VEHICLE IS NOT EQUIPPED WITH AN AIR BAG OFF SWITCH.
Remedy: TO BRING THE STANDARD CAB AND CARGO VAN VEHICLES INTO COMPLIANCE, DEALERS WILL INJECT EPOXY INTO THE AIR BAG OFF SWITCH TO PREVENT AIR BAG ACTIVATION, RELOCATE THE SWITCH BEHIND THE INSTRUMENT PANEL AND THEN INSTALL A COVER OVER THE RESULTING OPENING. THE SUN VISOR LABEL AND OWNER'S MANUAL WILL ALSO BE CHANGED. THE CORRECTION FOR THE EXTENDED CAB VEHICLE WILL CONSIST OF CHANGING THE FRONT PASSENGER SEAT TO A SEAT THAT HAS CHILD RESTRAINT LOWER ANCHORAGES. THE RECALL BEGAN ON SEPTEMBER 9, 2004. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438 OR GMC AT 1-866-996-9463.
ON CERTAIN PICKUP TRUCKS AND SPORT UTILITY VEHICLES, THE GALVANIZED STEEL TAILGATE SUPPORT CABLES THAT RETAIN THE TAILGATE IN THE FULL OPEN (HORIZONTAL) POSITION MAY CORRODE, WEAKEN, AND EVENTUALLY FRACTURE. IF BOTH CABLES FRACTURED, THE TAILGATE WOULD SUDDENLY DROP AND STRIKE THE TOP SURFACE OF THE REAR BUMPER.
Consequence & remedy
Consequence: ANYONE SITTING OR STANDING ON THE HORIZONTAL SURFACE OF THE TAILGATE WHEN BOTH CABLES FRACTURED COULD BE INJURED BY FALLING FROM THE TAILGATE. ON VEHICLES THAT HAVE HAD THE BUMPER REMOVED, THE TAILGATE MAY DROP EVEN LOWER. ADDITIONALLY, IF THERE IS CARGO ON THE TAILGATE THE CARGO MAY FALL OFF IF THE SUPPORT CABLES FRACTURE.
Remedy: DEALERS WILL REPLACE THE CABLES. INTERIM OWNER NOTIFICATION BEGAN ON APRIL 7, 20004. THE RECALL BEGAN ON SEPTEMBER 24, 2004, WHEN REPLACEMENT PARTS WERE AVAILABLE, AND WILL CONTINUE THROUGH OCTOBER 29, 2004. OWNERS SHOULD CONTACT CADILLAC AT 1-866-982-2339, CHEVROLET AT 1-800-630-2438 OR GMC AT 1-866-996-9463, OR VISIT WWW.MYGMLINK.COM, AND ENTER YOUR VEHICLE IDENTIFICATION NUMBER.
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.
