Official recalls
605V161000 · Parking Brake
Apr 22, 2005
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.
05V163000 · 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.
04V225000 · Seat Belts:front:anchorage
May 11, 2004
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.
04V129000 · Structure:body:tailgate:hinge And Attachments
Mar 17, 2004
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.
04V045000 · Service Brakes, Hydraulic
Feb 4, 2004
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.
03V018000 · Visibility:windshield
Jan 23, 2003
CERTAIN PICKUP TRUCKS FAIL TO CONFORM TO FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 212, "WINDSHIELD MOUNTING." SOME OF THESE VEHICLES LACK A CONTINUOUS URETHANE BONDING BEAD BETWEEN THE BODY SURFACE AND THE WINDSHIELD.
Consequence & remedy
Consequence: IN VEHICLES WITH THIS CONDITION, THE WINDSHIELD MAY NOT BE RETAINED IN ACCORDANCE WITH THE SAFETY STANDARD DURING A VEHICLE CRASH.
Remedy: DEALERS WILL REMOVE, RESEAL, AND REINSTALL THE WINDSHIELD. OWNER NOTIFICATION BEGAN ON JANUARY 28, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020 OR GMC AT 1-800-462-8782.

Status: closed (inferred from source dates) · Service Brakes, Hydraulic; Service Brakes, Hydraulic:power Assist:hydraulic:hoses, Lines/piping, And Fittings
The Office of Defects Investigation (ODI) received Defect Petition DP10-003 on March 2, 2010, requesting the investigation of model year (MY) 2003 Chevrolet Silverado 2500HD 4WD pickup trucks for corrosion failures of the vehicle brake lines.DP10-003 was granted and on March 30, 2010, Preliminary Evaluation PE10-010 was opened on more than six million model year 1999 through 2003 light trucks and sport utility vehicles manufactured and sold by General Motors Corporation (GM).On July 2, 2010, ODI received GM's response to an information request, which included GM's assessment of the frequency and safety consequences of the alleged defect. GM stated that:(1) the brake system of the subject vehicles is split front/rear and should a brake pipe suddenly fail for any reason, the affected vehicle would be capable of stopping with the pressure supplied by the remaining circuit; (2) the subject vehicles were designed to meet the hydraulic circuit partial failure requirements of Federal Motor Vehicle Safety Standards 105 and 135, Light Vehicle Brake Systems; and (3) should a brake fluid leak occur for any reason, the brake system malfunction indicator lamp (MIL) would illuminate and warn the driver before the brake fluid level was low enough to cause a loss of line pressure.ODI's and GM's analysis indicates that 85 percent of the complaints occurred on vehicles used primarily in States that use salt on the roads during Winter months (Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia and Wisconsin).Overall the complaint rates per 100,000 vehicles for Salt Belt States is 43.0 and Non-Salt Belt is 3.0.In approximately 25 percent of the complaints the brake pipe failure occurred suddenly, with no warning (i.e., no MIL, Brake Fluid Loss Warning), and resulted in extended stopping distances.In 30 of these the increase in stopping distance that resulted was a factor in the crash and in 10 others the vehicle was intentionally steered off the road or into another lane of travel in order to avoid a crash.This investigation has been upgraded to an Engineering Analysis (EA11-001) for subject vehicles sold or currently registered in Salt Belt States to further assess the scope, frequency and safety risks associated with sudden failures of corroded brake pipes that can result in decreased brake effectiveness. ODI will continue to gather information on subject vehicles outside the Salt Belt as well.

PE03057 · Parking Brake Failure
Opened Dec 8, 2003 · Closed Apr 9, 2004
Status: closed (inferred from source dates) · Parking Brake
ODI OPENED PE03-057 TO ASSESS PARKING BRAKE INEFFECTIVENESS IN THE SUBJECT VEHICLES.THESE VEHICLES ARE EQUIPPED WITH FOUR WHEEL DISC BRAKES THAT INCORPORATE A SINGLE-SHOE DRUM-IN-HAT PARKING BRAKE INDEPENDENT OF THE SERVICE BRAKES.COMPLAINT AND WARRANTY DATA INDICATE THAT THE PARKING BRAKE LININGS TEND TO WEAR OUT EARLY IN THE LIFE OF THE VEHICLE (AT AN AVERAGE OF 24 MONTHS IN SERVICE), REDUCING THE PARKING BRAKE SYSTEM'S TORQUE BELOW THAT NEEDED TO IMMOBILIZE THE VEHICLE.GM HAS ATTRIBUTED THIS ACCELERATED WEAR TO FOREIGN MATERIAL INTRUSION AND A FAILURE OF THE BRAKE SHOE TO PROPERLY SELF-CENTER WITHIN ITS BRAKE DRUM.EFFECTIVE WITH THE START OF MY 2003 PRODUCTION, A NEWER REDUCED FORCE HOLD-DOWN CLIP WAS INTRODUCED TO FACILITATE BRAKE SHOE DISENGAGEMENT FROM THE DRUM SURFACE.THIS PART IS ALSO AVAILABLE AT THE SERVICE LEVEL FOR THE MY 1999-2002 VEHICLES.GM HAS INDICATED THAT THE PAKING BRAKE IS INTENDED TO OPERATE IN CONJUNCTION WITH THE TRANSMISSION TO IMMOBILZE PARKED VEHICLES, AND THAT IN MANY CASES, ACCELERATED PARKING BRAKE LINING WEAR IS CAUSED BY ROUGH USE, VEHICLE MODIFICATIONS, AND DRIVING WITH THE PARKING ENGAGED. ODI HAS UPGRADED THE PRELIMINARY EVALUATION TO AN ENGINEERING ANALYSIS TO GATHER FURTHER INFORMATION CONCERNING PARKING BRAKE USAGE FACTORS AND THE CIRCUMSTANCES SURROUNDING THE SEVENTEEN REPORTED VEHICLE CRASHES.
