THE SPARE TIRE FELL OFF THE TRUCK. IS HELD ON BY A HOIST AND CABLE SYSTEM. THE CABLE BROKE ALLOWING THE TIRE TO FALL TO THE GROUND. LUCKILY THE VEHICLE WAS BEING BACKED OUT OF THE GARAGE AND NOT GOING DOWN THE ROAD WHEN IT HAPPENED. THIS COULD HAVE BEEN FATAL FOR MY FAMILY OR OTHERS ON THE ROAD! SO FAR I HAVE CALLED THE DEALERSHIP AND GMC. THEY WANT TO SCHEDULE AN APPOINTMENT BUT AS OF RIGHT NOW DO NOT WANT TO COVER THE PART BECAUSE ITS MORE THAN SEVEN YEARS OLD. THIS IS NOT ACCEPTABLE. THIS PART FAILED AND COULD HAVE CAUSED INJURY TO MY FAMILY AND OR OTHERS. INCIDENT HAPPENED THIS MORNING ON 12/9/11. *TR

TL*- THE CONTACT OWNS A 2001 GMC YUKON. WHILE DRIVING HE HEARD A LOUD NOISE THAT SOUNDED LIKE METAL CLASHING ON METAL. THE CONTACT TOOK IT TO THE DEALER, AND THEY STATED THAT THE FAILURE WAS DUE TO A A DEFECTIVE FLEX PLATE. HE FELT THAT THIS WAS A HUGE SAFETY PROBLEM BECAUSE THE FAILURE COULD RESULT IN A LOSS OF THE ABILITY TO STOP THE VEHICLE. ALSO, THIS WAS A HUGE CONCERN FOR ANYONE WHO WAS PULLING A TRAVEL TRAILER. THE CONTACT COULD PROVIDE PICTURES IF NEEDED. THE FAILURE WAS 80,000 MILES. *AK THE NOISE WAS NOTICED A IDLE AND PARTICULARLY AT ACCELERATION. IT WAS DETERMINED THAT THE FLEX PLATE CONNECTING THE CRANK TORQUE CONVERTER WAS FRACTURED. THE CONSUMER STATED THE PROBABLE FAILURE MODE ON THIS PART IS FLEXURAL FATIGUE WHICH WOULD RESULT MISALIGNMENT OF THE TRANSMISSION INPUT SHAFT AND THE CRANKSHAFT, OR EXCESSIVE RUN OUT ON THE ATTACHMENT SURFACE OF EITHER THE CRANKSHAFT OR THE CONVERTER.

I OPENED BACK REAR LIFT GLASS AND IT MADE A VERY STRANGE NOISE. I CLOSED IT THEN NOTICED IT WAS NOT SITTING STRAIGHT SO I OPENED IT AGAIN TO SEE WHAT THE PROBLEM WAS. WHEN I TRIED TO CLOSE IT AGAIN IT WOULD NOT LOCK AND THEN ONE HINGE HOLDING THE GLASS ON JUST BROKE AND THEN THE GLASS WAS ONLY HELD ON BY ONE HINGE AND WAS COMPLETELY CROOKED. I CONTACTED GMC DEALER AND THEY SAID $1,100.00 REPAIR BECAUSE THEY HAD TO REPAIR THE WHOLE GLASS PLUS THE HINGES. I FOUND OUT THAT A COUPLE OTHER PEOPLE IN MY SMALL AREA HAD THE SAME PROBLEM AND THEN I FOUND SOMEWHERE ON THIS WEBSITE THERE HAD BEEN 3 MORE COMPLAINTS ABOUT IT. WHEN I SPOKE WITH GMC THEY SAID IT WASN'T ANYTHING I DID AND IT WASN'T DUE FROM WEAR AND TEAR THAT IT JUST BROKE. APPARENTLY THE PART THAT BROKE ON MINE WAS THE WELDING CAME OFF. I THINK IF AN INVESTIGATION IS STARTED THAT GMC WILL FIND OUT THERE ARE A LOT MORE PEOPLE IN THIS COUNTRY WHO HAVE HAD THE SAME PROBLEM. *JB

I CURRENTLY OWN (PURCHASED NEW) A 2001 YUKON XL WHICH IS EQUIPPED WITH A REAR TAILGATE HAVING A HINGED REAR WINDOW WHICH ALLOWS ACCESS TO THE REAR COMPARTMENT WITHOUT OPENING THE TAILGATE. *AK THE REAR TAILGATE GLASS IS SECURED TO THE TAILGATE VIA TWO HINGES WHICH ARE SECURED TO THE GLASS BY AN ADHESIVE. THE PASSENGER SIDE WINDOW HINGE HAS DELAMINATED FROM THE TAILGATE GLASS RESULTING IN THE WINDOW BEING SECURED TO THE VEHICLE WITH ONE HINGE. THERE IS NO MECHANICAL SECUREMENT TO THE GLASS. I HAVE BEEN TOLD BY SEVERAL DIFFERENT SERVICE PROFESSIONALS (INSIDE AND OUT OF GM) THAT THIS IS A KNOWN PROBLEM. HOWEVER, NO SERVICE BULLETINS OR RECALLS EXIST TO REPAIR THE HINGE FAILURE. I HAVE BEEN ATTEMPTING TO WORK THIS ISSUE WITH THE GMC CUSTOMER SERVICE TEAM AND HAVE A CASE OPENED (1-122096729). I BELIEVE THAT OPENING THE DOOR WINDOWS ON THE VEHICLE WOULD CAUSE ADDITIONAL STRESS ON THE REMAINING HINGE. THEREFORE, I BELIEVE THIS IS A POTENTIAL SAFETY ISSUE SINCE THE WINDOW COULD BREAK FREE FROM THE VEHICLE IF THE SECOND HINGE FAILS RESULTING IN A SAFETY HAZARD FOR ANY VEHICLE DIRECTLY BEHIND OR ADJACENT TO THE VEHICLE. IF YOU HAVE ANY QUESTIONS, PLEASE CALL.

Official recalls
4Aug 29, 2005
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.
Consequence & remedy
Consequence: THIS CAN CAUSE INCREASED STOPPING DISTANCES DURING LOW-SPEED BRAKE APPLICATIONS, WHICH COULD RESULT IN A CRASH.
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.
Apr 14, 2005
CERTAIN TRUCKS AND SPORT UTILITY VEHICLES WERE BUILT WITH FUEL MODULE RESERVOIR ASSEMBLIES THAT CONTAIN FUEL PUMP WIRES CONNECTORS MAY OVERHEAT UNDER CERTAIN OPERATING CONDITIONS.
Consequence & remedy
Consequence: IF THE IGNITION CIRCUIT WIRE IS EXPOSED, THE FUEL PUMP FUSE WILL BLOW, DISABLING THE FUEL PUMP AND CAUSING AN ENGINE STALL OR NO-START CONDITION. IF SUFFICIENT HEAT IS CONDUCTED TO THE PASS-THROUGH CONNECTOR, A HOLE IN THE CONNECTOR MAY RESULT, WHICH MAY CAUSE A 'SERVICE ENGINE SOON' LIGHT TO BE ILLUMINATED DURING THE EMISSION SYSTEM DIAGNOSTIC ROUTINE. FUEL VAPOR AND IN SOME CASES LIQUID FUEL MAY LEAK OUT OF THE FUEL TANK THROUGH THE HOLE IN THE CONNECTOR BODY. FUEL LEAKAGE, IN THE PRESENCE OF AN IGNITION SOURCE, COULD RESULT IN A FIRE. ALSO IF THE IGNITION CIRCUIT OR GROUND WIRE IS EXPOSED AND SHORTS TO THE FUEL LEVEL SENDER CARD WIRES, INACCURATE FUEL LEVEL READINGS MAY RESULT.
Remedy: DEALERS WILL REMOVE THE FUEL TANK, AND REMOVE THE MODULE RESERVOIR ASSEMBLIES FROM THE TANK, AND INSTALL A NEW SERVICE KIT FREE OF CHARGE. AN INTERIM LETTER TO OWNERS WAS MAILED ON MAY 25, 2005. THE OWNERS WERE RE-NOTIFIED ON OCTOBER 19, 2005, SINCE PARTS ARE NOW AVAILABE. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438 AND GMC AT 1-866-996-9463.

VEHICLE DESCRIPTION: PICKUP AND UTILITY TRUCKS. SOME OF THESE VEHICLES HAVE AN INTERNAL COMPONENT IN THE OUTBOARD SEAT BELT RETRACTORS FOR THE 2ND AND 3RD ROW OF SEATS THAT COULD BE CRACKED. WITH REPEATED ACTUATION OF THE LOCKING MECHANISM, THE CRACK COULD SPREAD TO THE POINT SUCH THAT THE SEAT BELT WOULD NO LONGER LOCK.
Consequence & remedy
Consequence: IN A CRASH, INCREASED OCCUPANT INJURY COULD RESULT FROM THE NO-LOCK CONDITION.
Remedy: DEALERS WILL INSPECT THE OUTBOARD SEAT BELTS FOR SPECIFIC LOT NUMBERS AND REPLACE THE BELTS IF NECESSARY. GM IS ENCLOSING AN INSPECTION PROCEDURE FOR THE OWNERS TO USE OR THEY CAN HAVE THEIR DEALERS DO THE INSPECTIONS. OWNER NOTIFICATION BEGAN JULY 2, 2001. 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.
Oct 25, 2000
VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS AND SPORT UTILITY VEHICLES. SOME OF THESE VEHICLES HAVE LOOSE OR MISSING REAR WHEELHOUSE PLUGS. UNDER CERTAIN VEHICLE OPERATING CONDITIONS, EXHAUST GASES CAN FLOW FORWARD AND ACCUMULATE IN THE REAR WHEELHOUSE.
Consequence & remedy
Consequence: THESE GASES COULD FLOW INTO THE PASSENGER COMPARTMENT IF THE PLUG IS MISSING OR LOOSE AND COULD CAUSE POSSIBLE ILLNESS, UNCONSCIOUSNESS, OR DEATH.
Remedy: DEALERS WILL INSPECT THE VEHICLE FOR LOOSE OR MISSING WHEELHOUSE PLUGS AND INSTALL NEW PLUGS IF NECESSARY.

IN A LETTER DATED APRIL 14, 2005, GENERAL MOTORS (GM) NOTIFIED ODI THAT IT HAD IDENTIFIED A DEFECT RELATED TO MOTOR VEHICLE SAFETY IN APPROXIMATELY 316,508 MODEL YEAR (MY) 2000-01 1500 SERIES CHEVROLET SUBURBAN AND GMC YUKON XL VEHICLES (RECALL 05V-155).GM DETERMINED THAT SOME OF THESE VEHICLES WERE EQUIPPED WITH FUEL MODULE RESERVOIR ASSEMBLIES (MRAS) THAT CONTAIN FUEL PUMP WIRES AND/OR CONNECTORS THAT MAY OVERHEAT UNDER CERTAIN OPERATING CONDITIONS.ACCORDING TO GM, FUEL PUMP WIRES THAT OVERHEAT MAY RESULT IN ONE OR MORE CONDITIONS THAT PRESENT RISKS TO MOTOR VEHICLE SAFETY:(1) FUEL LEAKAGE FROM THE MRA PASS-THROUGH CONNECTOR IF THE OVERHEATING PRODUCES A HOLE IN THE PLASTIC CONNECTOR; (2) ENGINE STALL IF WIRING EXPOSED BY THE OVERHEATING SHORTS TO GROUND AND CAUSES THE FUEL PUMP FUSE TO BLOW; OR (3) INACCURATE FUEL LEVEL READINGS IF OVERHEATED WIRING IS SHORTED TO THE FUEL LEVEL SENDER CARD.GM'S ANALYSIS IDENTIFIED THE CAUSE OF THE OVERHEATED WIRING AS A HIGH-RESISTANCE CONDITION IN THE MRA CONNECTOR CONTACTS DUE TO FRETTING CORROSION THAT MAY DEVELOP OVER TIME.GM DETERMINED THAT THE CORROSION IS CAUSED BY MOVEMENT BETWEEN THE CONTACT SURFACES AND THAT SUCH MOVEMENT IS PRIMARILY INFLUENCED BY CHASSIS AND FUEL TANK VIRBRATION CHARACTERISTICS.GM'S TESTING FOUND THAT THE FUEL TANK VIBRATION CHARACTERISTICS OF THE RECALLED MY 2000-01 1500-SERIES VEHICLES WERE SIGNIFICANTLY GREATER THAN IN OTHER GM VEHICLES EQUIPPED WITH THE SAME MRA CONNECTORS.THESE VEHICLES HAD THE HIGHEST RATE OF RELATED FUEL LEAK AND STALL COMPLAINTS; AND A RECENT SURVEY CONDUCTED BY GM FOUND EVIDENCE OF MRA WIRING OVER-HEATING IN ALMOST ONE-THIRD OF THE 1500-SERIES VEHICLES INSPECTED. OTHER VEHICLES EQUIPPED WITH THE SUBJECT MRA CONNECTOR AND EVALUATED DURING THIS INVESTIGATION INCLUDE APPROXIMATELY 33,000 MY 2000-01 2500-SERIES SUBUBRAN AND YUKON XL VEHICLES, WHICH FALL WITHIN THE SCOPE OF EA04-026, AND PEER POPULATIONS OF SHORT WHEELBASE YUKON AND TAHOE UTILITY VEHICLES AND FULL-SIZE SILVERADO AND SIERRA PICKUP TRUCKS. THESE VEHICLES ARE NOT INCLUDED IN RECALL 05V-155 FOR THE FOLLOWING REASONS:(1) THESE VEHICLES ARE EQUIPPED WITH FUEL TANKS WITH SIGNIFICANTLY LESS VIBRATION AT THE MRA INTERFACE THAN THE RECALLED VEHICLES; (2) THE POTENTIAL FOR FUEL LEAKAGE IS SUBSTANTIALLY LOWER IN THE PICKUP TRUCKS AND SHORT-WHEELBASE UTILITY VEHICLES DUE TO DIFFERENCES IN FUEL TANK CONFIGURATION AND NO INCIDENTS OF FUEL LEAKAGE DUE TO OVERHEATED WIRING WERE VERIFIED IN THESE VEHICLES; (3) THERE THERE HAVE BEEN ONLY THREE POTENTIALLY RELATED COMPLAINTS OF FUEL LEAKAGE ASSOCIATED WITH THE OVERHEATED WIRING CONDITION IN THE 2500-SERIES LONG-WHEELBASE UTILITY VEHICLES; AND (4) NO EVIDENCE OF OVERHEATED WIRING WAS FOUND IN THE 2500-SERIES SUBURBAN AND YUKON XL VEHICLES AND PICKUP TRUCKS INSPECTED BY GM IN ITS VEHICLE SURVEY EFFORTS AND THE RATE FOUND IN THE SHORT-WHEELBASE UTILITIES WAS LOWER THAN THE RECALLED VEHICLES BY AN ORDER OF MAGNITUDE. ODI WILL CONTINUE TO MONITOR THE EXPERIENCE IN THE 2500 SERIES MY 2000-01 LONG-WHEELBASE UTILITY VEHICLES.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS FOR THE 2500 SERIES VEHICLES.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY A CHANGE IN CIRCUMSTANCES.

THE FUEL PUMP WIRING AND CONNECTOR MAY OVERHEAT AND MELT A HOLE IN THE TOP OF THE FUEL PUMP MODULE.POSSIBLE CONSEQUENCES INCLUDE FUEL TANK LEAKAGE AND ENGINE STALL WITH NO RESTART.FOURTEEN OF THE 20 COMPLAINTS TO ODI ALLEGE FUEL TANK LEAKAGE, INCLUDING ONE THAT REPORTED THAT A FIRE DEPARTMENT WAS CALLED TO THE SCENE AFTER A POOL OF GASOLINE WAS DISCOVERED BENEATH THE VEHICLE.MOST OF THE ODI COMPLAINTS REPORT INCIDENTS THAT OCCURRED WITHIN THE PAST YEAR. ACCORDING TO GM, FUEL LEAKAGE CAN OCCUR IN THE SUBJECT VEHICLES IF THE HEAT IS SUFFICIENT TO MELT A HOLE IN THE PLASTIC CONNECTOR LARGE ENOUGH FOR LIQUID FUEL TO FLOW THROUGH.ON-BOARD EMISSIONS DIAGNOSTICS MAY DETECT HOLES THAT ARE APPROXIMATELY 0.040 INCHES OR MORE AND SET A SERVICE ENGINE SOON WARNING LIGHT.THE CONNECTOR POSITION IN THE SUBJECT VEHICLES IS BELOW THE FUEL LEVEL WHEN THE TANK IS FULL.WHILE GM DOES NOT KNOW HOW MUCH FUEL COULD LEAK FROM A TANK WITH A MELTED FUEL PUMP CONNECTOR, SEVERAL CONSUMERS HAVE REPORTED SIGNIFICANT LEAK EVENTS.ENGINE STALL CAN OCCUR IF:(1) A SHORT OCCURS IN THE PUMP WIRING (BARE WIRE EXPOSED BY MELTED INSULATION SHORTS AGAINST A GROUND OR GROUND WIRE) AND THE FUEL PUMP RELAY FUSE IS BLOWN; OR (2) THE VEHICLE RUNS OUT OF FUEL DUE TO AN INACCURATE FUEL GAUGE READING RESULTING FROM AN ELECTRICAL SHORT BETWEEN THE FUEL PUMP WIRING AND THE LEVEL SENSOR WIRING. GM'S ANALYSIS OF FIVE ASSEMBLIES RETURNED FROM INCIDENT VEHICLES DETERMINED THAT THE CONDITION IS CAUSED BY ELEVATED RESISTANCE/ ARCING AT THE MRA UNDERCOVER B CAVITY TERMINAL OF THE FOUR-WAY 150 METRI-PAK CONNECTOR.GM ATTRIBUTES THE HIGH RESISTANCE AND ARCING TO A DEPRESSED CONTACT ARM AT THE 150 METRI-PAK B CAVITY FEMALE TERMINAL.GM IS CONTINUING ITS INVESTIGATION TO COMPLETE ITS ROOT CAUSE ANALYSIS. MODULAR RESERVOIR ASSEMBLIES USING THE 150 METRI-PAK CONNECTORS WERE USED BY GM IN SEVERAL MILLION C/K-SERIES SPORT UTILITY VEHICLES AND PICKUP TRUCKS FROM MY 1997 THROUGH 2002, WHEN GM RELEASED A METAL MRA COVER AND A 280 METRI-PAK CONNECTOR IN THE SUBJECT VEHICLES.DURING PE04-042, ODI COLLECTED INFORMATION FROM GM CONCERNING MY 2000-2002 C/K SUV'S AND PICKUP TRUCKS.THE SUBJECT VEHICLES COMPRISE APPROXIMATELY 9 PERCENT OF PRODUCTION FOR THOSE VEHICLES AND ABOUT 39 PERCENT OF COMPLAINTS TO GM. THIS INVESTIGATION HAS BEEN UPGRADED TO AN ENGINEERING ANALYSIS TO FURTHER ASSESS THE SCOPE, FREQUENCY, AND SAFETY CONSEQUENCES OF THE ALLEGED DEFECT IN GM C/K-SERIES VEHICLES.

THIS INVESTIGATION INVOLVES THE GENERAL MOTORS CORPORATION (GM)THROTTLE BODY (TB) UTILIZED IN MODEL YEAR (MY) 1999-2002 SILVERADO, SIERRA, TAHOE, SUBURBAN, AVALANCHE AND YUKON (SUBJECT VEHICLE(S)) WITH 4.8L, 5.3L, AND 6.0L ENGINES. THE TB VALVE MAY INTERMITTENTLY STICK IN A CLOSED POSITION.IN SUCH A SITUATION, AN OPERATOR MAY APPLY ADDITIONAL ACCELERATOR PEDAL FORCE TO INCREASE ENGINE SPEED.THE APPLICATION OF ADDITIONAL ACCELERATOR PEDAL FORCE, TO OPEN A STUCK THROTTLE VALVE, MAY OPEN THE THROTTLE VALVE MORE THAN INTENDED AND, IN TURN, ACCELERATE THE ENGINE AND VEHICLE MORE THAN INTENDED AND REASONABLY EXPECTED BY THE DRIVER.ON AUGUST 1, 2002, THE OFFICE OF DEFECTS INVESTIGATION (ODI), OF THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION (NHTSA), OPENED THIS ENGINEERING ANALYSIS.THE INVESTIGATION REVEALED THAT TWO FACTORS MAY CAUSE THE DEFECT: 1) TB MANUFACTURING PROCESS PROBLEMS; AND 2) ACCUMULATION OF DEPOSITS (A PCV SYSTEM BY-PRODUCT) ON OR AROUND THE TB THROTTLE VALVE AND BORE.ODI CONCLUDES THAT THE TB PERFORMS IN A DEFECTIVE MANNER AFTER ANALYZING GM?S DATA SUBMISSIONS, AND TEST DATA COLLECTED BY THE VEHICLE RESEARCH AND TEST CENTER (VRTC).FIFTY-NINE CRASHES ARE ALLEGED TO HAVE OCCURRED AS A RESULT OF GM?S TB DEFECT.THE MAJORITY OF THE CRASHES INVOLVE A SINGLE VEHICLE, ENGAGING IN A CLOSE QUARTER VEHICLE MANEUVER (OR LOW SPEED), AND CAUSING ONLY MINOR PROPERTY DAMAGE.FOUR OUT OF THE FIFTY-NINE CRASHES INVOLVE INJURY, AND THOSE INJURIES WERE MINOR.ALTHOUGH GM?S TB IS DEFECTIVE, BASED ON THE EVIDENCE GATHERED, ODI HAS FOUND THAT THE ACCELERATOR PEDAL FORCE REQUIRED TO OPEN A STUCK THROTTLE VALVE IS NEGLIGIBLE, AND THE THROTTLE VALVE DOES NOT STICK IN THE OPEN POSITION.THEREFORE THIS ENGINEERING ANALYSIS (EA02-015) WILL BE CLOSED AT THIS TIME.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.FOR A DETAILED DISCUSSION OF THE TB COMPONENT AND TESTING, PLEASE SEE THE ATTACHED REPORT.
