GMC Yukon 2000–2006

Cause

CERTAIN PICKUP TRUCKS AND SPORT UTILITY VEHICLES MAY EXPERIENCE UNWANTED ANTILOCK BRAKE SYSTEM (ABS) ACTIVATION. THIS CONDITION IS MORE LIKELY TO OCCUR IN ENVIRONMENTALLY CORROSIVE AREAS. THIS RECALL WILL BE LAUNCHED IN THE "SALT BELT" STATES OF CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MARYLAND, MASSACHUSETTS, MAINE, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, WISCONSIN AND THE DISTRICT OF COLUMBIA ONLY.

Remedy

DEALERS ARE TO REMOVE THE WHEEL SPEED SENSOR AND THOROUGHLY CLEAN THE WHEEL SPEED SENSOR MOUNTING SURFACE ON THE BEARING, APPLY RUST INHIBITOR TO THE CLEANED SURFACE, GREASE THE MOUNTING SURFACE, REINSTALL THE WHEEL SPEED SENSOR, AND CHECK THE PEAK-TO-PEAK OUTPUT VOLTAGE TO ENSURE THE WHEEL SPEED SIGNAL IS WITHIN SPECIFICATIONS. THE RECALL BEGAN SEPTEMBER 22, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438 OR GMC AT 1-866-996-9463.

Consequence

THIS CAN CAUSE INCREASED STOPPING DISTANCES DURING LOW-SPEED BRAKE APPLICATIONS, WHICH COULD RESULT IN A CRASH.

Cause

Certain vehicles located in Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland & Labrador may experience unwanted Antilock Brake System (ABS) activation and increased stopping distances during low-speed brake application (less than 16 km/h and greater than 6 km/h). This condition does not set any ABS codes nor does it illuminate the ABS warning lamp. Correction: Dealers will remove the wheel speed sensor and thoroughly clean the wheel speed sensor mounting surface on the bearing, apply Zinc-X to the cleaned surface, grease the mounting surface, reinstall the wheel speed sensor, and check the output voltage to ensure the wheel speed signal is within specifications.

Fault

WHEN SLOWING DOWN AT AN INTERSECTION STOP LIGHT, AT THE SPEED OF UNDER 10 MPH (= 16.1 km/h), THE ABS BRAKES SUDDENLY KICKED IN AND PULSATED, NOT ALLOWING THE TRUCK TO STOP.

Remedy

EVEN THOUGH THERE WAS NO ABS WARNING LIGHT OR ERROR CODE, WE ELECTED TO REPLACE BOTH ABS SPEED SENSORS AS A PRECAUTION. (1 more)

Inspection

AFTER TAKING THE VEHICLE TO THE MECHANICS THEY COULD NOT DIAGNOSE A PROBLEM.

Consequence

THIS ALMOST RESULTED IN A REAR END COLLISION WITH A STOPPED VEHICLE IN FRONT OF ME.

Fault

AT RELATIVELY LOW SPEEDS HE EXPERIENCES UNWANTED ANTI-LOCK BRAKE ACTIVATION.

Remedy

THE VEHICLE HAS NOT BEEN REPAIRED FOR THE MALFUNCTION.

Outcome

THE FAILURE RE-OCCURRED OVER A PERIOD OF TIME. (1 more)

Fault

AT SLOW BRAKING SPEEDS {AT 5 MPH (= 8.05 km/h)} THE ABS BRAKES GO OFF EVERY TIME YOU STOP. (1 more)

Remedy

I REMOVED THE FUSES THAT CONTROL THE ABS BRAKING SO THAT I CAN CONTROL MY BRAKING.

Consequence

WHEN THEY LOCK UP, AND YOUR CANNOT STOP OR CONTROL THE BRAKING, YOU RUN INTO THE CARS PARKED IN FRONT OF ME.

Fault

THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 5 MPH (= 8.05 km/h), THE BRAKES FAILED TO ENGAGE WHEN DEPRESSED AND THE BRAKE PEDAL ABNORMALLY TRAVELED TO THE FLOOR BOARD. (1 more)

Remedy

THE VEHICLE WAS NOT REPAIRED. (1 more)

Inspection

THEY FOUND THE LEFT REAR BRAKE LINE HAD RUPTURED DUE TO RUST.

Consequence

NARROWLY AVOIDED REAR ENDING CAR IN FRONT OF ME AT HIGH SPEED. (1 more)

Fault

AFTER NO WARNING (LIGHTS, CHIMES OR ALARMS), APPLIED BRAKES AND PEDAL WENT TO THE FLOOR. NO BRAKES. (1 more)

Cause

EVERYONE KNOWS WHEN YOU PLACE DIFFERENT METALS IN CONTACT WHERE THEY CAN GET WET, YOU WILL GET ELECTRO-CHEMICAL CORROSION OF THE WEAKER METAL, IN THIS CASE, ALUMINUM. (1 more)

Inspection

*TR LOCAL DEALER SAYS ALUMINUM BRAKE LINES WERE SEVERELY CORRODED AND HAD RUPTURED.

Consequence

LUCKILY IT WAS VERY EARLY AND NOBODY WAS ON THE ROAD WHEN I BLEW THROUGH A STOP SIGN INTERSECTION.

Cause

ON CERTAIN PICKUP AND UTILITY TRUCKS, SOME OF THESE VEHICLES HAVE AN AIR BAG SENSING DIAGNOSTIC MODULE (SDM) WHICH CONTAINS AN ANOMALY THAT COULD RESULT IN THE DRIVER AND PASSENGER'S AIR BAG FAILING TO DEPLOY DURING CERTAIN FRONTAL CRASHES.

Remedy

DEALERS WILL RECALIBRATE THE SDM ON THE AFFECTED VEHICLES. OWNER NOTIFICATION BEGAN AUGUST 28, 2002. 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.

Consequence

IN A VEHICLE CRASH, FRONT SEAT OCCUPANTS MAY RECEIVE MORE SEVERE INJURIES.

Cause

Certain vehicles have an air bag sensing diagnostic module (SDM) which contains an anomaly that could result in the driver and passenger's air bag failing to deploy during certain frontal collisions. In a vehicle crash, front seat occupants may receive more severe injuries. Correction: Dealers will recalibrate the SDM.

Fault

THE PARKING BRAKE ON MY 2000 YUKON WOULD NOT HOLD THE VEHICLE WHEN THE PARKING BRAKE WAS APPLIED AND THE TRANSMISSION WAS IN NEUTRAL.

Consequence

THESE GASES COULD FLOW INTO THE PASSENGER COMPARTMENT IF THE PLUG IS MISSING OR LOOSE AND COULD CAUSE POSSIBLE ILLNESS, UNCONSCIOUSNESS, OR DEATH.

Cause

Certain vehicles may have loose or missing rear wheelhouse plugs. Under certain operating conditions, exhaust gases can flow forward and accumulate in the rear wheelhouse. These exhaust gases could flow into the passenger compartment if the wheelhouse plug is missing or loose and may cause possible illness, unconsciousness or death. Correction: Dealers will inspect for loose or missing wheelhouse plugs, and install new plugs if necessary.

THIS CONDITION MAY CAUSE AN INADEQUATE SEAL AT THE CONNECTION, POTENTIALLY LEADING TO A FUEL LEAK. IN THE PRESENCE OF AN IGNITION SOURCE, A FIRE COULD OCCUR.

Cause

VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS AND SPORT UTILITY VEHICLES. SOME OF THESE VEHICLES HAVE A CLEARANCE CONDITION BETWEEN THE FRONT RIGHT-HAND BRAKE PIPE AND THE BODY CROSS SILL THAT COULD DECREASE TO THE POINT OF ALLOWING CONTACT DURING THE LIFE OF THE VEHICLE. IF CONTACT OCCURS AND THE BRAKE PIPE BECOMES DAMAGED, IN HALF OF THE BRAKE SYSTEM THERE CAN BE A LOSS OF BRAKE FLUID AND PRESSURE. THE BRAKE WARNING LAMP WILL BE ACTIVATED WHEN THE BRAKE FLUID LEVEL REACHES THE INDICATOR LIMIT.

Remedy

DEALERS WILL INSPECT THE FRONT RIGHT-HAND BRAKE PIPE FOR WEAR. IF THERE ARE SIGNS OF WEAR, THIS SECTION OF THE BRAKE PIPE WILL BE REPLACED WITH A NEW DESIGNED BRAKE PIPE SECTION. IF THERE ARE NOT SIGNS OF WEAR ON THE BRAKE PIPE, THE DEALER WILL INSTALL A SPACER CLIP TO ENSURE SUFFICIENT CLEARANCE BETWEEN THE BRAKE PIPE AND THE BODY CROSS SILL.

Consequence

DURING BRAKING, THE PEDAL WILL BE LOWER THAN NORMAL AND STOPPING DISTANCES WILL BE LONGER. IF THIS OCCURS WHEN STOPPING DISTANCE IS LIMITED, A CRASH COULD OCCUR.

Cause

ON CERTAIN SPORT UTILITY VEHICLES EQUIPPED WITH REARWARD FOLDING HEAD RESTRAINTS ON THE SECOND ROW SEATS, TWO POTENTIAL PINCH POINTS EXIST ON EACH OF THE FOLDING HEAD RESTRAINTS WHEN THE RESTRAINTS ARE FOLDED REARWARD AS THE SEATBACK IS FOLDED DOWN.

Remedy

DEALERS WILL INSTALL PROTECTIVE COVERS OVER THE PINCH POINTS. OWNER NOTIFICATION BEGAN NOVEMBER 8, 2002. 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, GMC AT 1-800-462-8782, OR CADILLAC AT 1-800-458-8006.

Consequence

IF A PERSON WERE TO INSERT THEIR FINGER(S) INTO THE PINCH POINT WHEN THE HEAD RESTRAINT FOLDS, IT COULD TRAP AND PINCH THE FINGER(S) CAUSING INJURY.

Cause

CERTAIN PICKUP TRUCK, VAN, AND MINI VAN CONVERSIONS EQUIPPED WITH SOUTHERN COMFORT BUILT RUNNING BOARDS THAT CONTAIN CERTAIN COURTESY LIGHTS MANUFACTURED BY AMERICAN TECHNOLOGY COMPONENTS, INC. THESE UNITS CONTAIN A COURTESY LIGHT OR LIGHTS THAT MIGHT OVERHEAT WHEN THE WIRE HARNESS IS EXPOSED TO EXCESSIVE MOISTURE AND ROAD SALT.

Remedy

This Preliminary Information communicates to the dealer the process for downloading or updating operating software for the Tire Pressure Monitor, Active Fuel Injector tester, multi media tester, PICO Scope, GR8 starting/charging tester  and Vehicle Data Recorder tools, giving website address and step by step instructions to complete the update.

Open the manufacturer’s document (PDF) ↗ The points above were read from this document.

Remedy

Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

Cause

On certain vehicles, the body cross sill may contact the front, right-hand brake pipe. This could eventually wear a hole in the brake pipe over the normal life of the vehicle and result in a brake fluid leak. This could ultimately result in a partial brake system failure and increased stopping distances. Correction: Dealers will inspect for brake pipe wear and replace worn section if necessary. A spacer clip will be installed to ensure adequate clearance.

Cause

Certain vehicles do not comply with the requirements of C.M.V.S.S. 105 - Hydraulic and Electric Brake Systems. Vehicles may have a kinked brake booster vacuum supply hose which could increase stopping distances in multiple brake applications. Correction: Brake vacuum booster supply hose will be rerouted.

Fault

THE CONTACT STATED THAT WHEN TRAVELING AT A LOW RATE OF SPEED THE VEHICLE WOULD SLIDE.

Remedy

THE MECHANIC REPLACED THE BRAKE BOOSTER ROTORS AND PADS BEFORE THE CONTACT TOOK THE VEHICLE TO THE DEALER. (1 more)

Inspection

THE CONTACT TOOK THE VEHICLE TO THE DEALER IN ORDER TO HAVE IT INSPECTED, AND WAS TOLD THAT THE FAILURE WAS WITH THE ANTI-LOCK BRAKING SYSTEM.

Remedy

GM is receiving damaged (cracked or broken) transmission cores returned to the reman facilities. The damage is being caused either in the removal process by the technician, or inadequate packaging or shipping. This bulletin advises the dealers to be more careful not to damage the transmissions during removal and to package the core properly for return.

Cause

Certain vehicles equipped with rearward folding head restraints on the second row seats. Two potential pinch points exist on each of the folding head restraints when the head restraint(s) are folded rearward as the seatback is folded down. If a person were to insert their finger(s) into the pinch point when the head restraint folds, it could trap and pinch the finger(s) causing injury. Correction: Dealers will install protective covers over the pinch points.

Fault

IT FAILED WHILE DRIVING CAUSING THE FULL SYSTEM TO FAIL.

Cause

THE ABS SYSTEM ON MY CAR FAILED BECAUSE OF THE ACTUAL COMPUTER CONTROL UNIT.

Remedy

THE FUSE CONTROLLING THE ABS SYSTEM HAD TO BE REMOVED AS THE PUMPS CONTROLLING THE SYSTEM WOULD NOT TURN OFF SINCE THE CONTROL UNIT FAILED.
