ODI'S REVIEW OF COMPLAINT DATA RECEIVED SINCE THE CLOSE OF EA04-011 REVEALED NO INDICATION THAT THE INVESTIGATION SHOULD BE RE-OPENED.MORE DETAILS CAN BE FOUND IN THE FEDERAL REGISTER NOTICE ENCLOSED IN THE DP05-009 PUBLIC FILE.ODI RESERVES THE RIGHT TO REOPEN THE INVESTIGATION IN THE FUTURE SHOULD CONDITIONS WARRANT.

IN A LETTER DATED AUGUST 29, 2005, GM NOTIFIED ODI THAT IT WAS RECALLING CERTAIN MODEL YEAR 1999 THROUGH 2002 C/K PICKUP TRUCKS AND SPORT UTILITY VEHICLES TO CORRECT A PROBLEM WITH ANTI-LOCK BRAKE SYSTEM (ABS) WHEEL SPEED SENSOR CORROSION THAT MAY RESULT IN UNWANTED ABS ACTIVATION AND EXTENDED STOPPING DISTANCES DURING LOW-SPEED BRAKING (RECALL 05V-379).GM'S RECALL COVERS APPROXIMATELY 804,000 VEHICLES CURRENTLY REGISTERED IN THE FOLLOWING 14 SALT-BELT STATES:CONNECTICUT, ILLINOIS, INDIANA, MASSACHUSETTS, MAINE, MICHIGAN, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, AND WEST VIRGINIA.THE RECALL PROCEDURE WILL INVOLVE REMOVING THE SENSOR, CLEANING THE MOUNTING SURFACE, APPLYING A RUST INHIBITOR (ZINC-X) TO THE SURFACE, AND REINSTALLING THE SENSOR.IF NECESSARY, THE SENSOR WILL BE REPLACED. THE POPULATION AND FAILURE REPORT DATA GIVEN IN THIS RESUME ARE FOR THE FULL REGION THAT HAS BEEN CONSIDERED BY ODI AS THE SALT-BELT.THAT INCLUDES DELAWARE, IOWA, MARYLAND, MINNESOTA, MISSOURI, WISCONSIN AND THE DISTRICT OF COLUMBIA IN ADDITION TO THE 14 STATES INCLUDED IN 05V-379.THE STATES COVERED BY GM'S RECALL HAVE THE HIGHEST INCIDENT RATES FOR THE SUBJECT CONDITION, ACCOUNTING FOR 91% OF THE INCIDENTS, BUT ONLY 24% OF SUBJECT VEHICLE SALES IN THE UNITED STATES.ODI'S ANALYSIS DETERMINED THAT 840 OF THE COMPLAINTS, 244 OF THE CRASHES, AND 16 OF THE INJURIES IDENTIFIED IN THIS INVESTIGATION OCCURRED IN THOSE STATES.THE RESULTING INCIDENT AND CRASH RATES ARE 96.2 AND 28.0 PER 100,000 VEHICLES RESPECTIVELY (NOTE:RATES ARE BASED ON VEHICLE SALES, NOT REGISTERED VEHICLES). THE CORRESPONDING NUMBERS IN THE EXCLUDED PORTIONS OF THE SALT-BELT ARE 399,000 VEHICLES, 81 INCIDENTS (20.3 PER 100,000 VEHICLES), 3 CRASHES, AND NO INJURIES.THE STATISTICS IN THE REMAINING 30 STATES ARE 2,406,000 VEHICLES, 168 INCIDENTS (7.0 PER 100,000 VEHICLES), 31 CRASHES, AND ONE INJURY.GM AND ODI ARE CONTINUING TO MONITOR THE PROBLEM EXPERIENCE IN STATES THAT ARE NOT INCLUDED IN THE RECALL.GM WILL PROVIDE ODI WITH UPDATED COMPLAINT, FIELD REPORT, AND WARRANTY DATA IN NOVEMBER 2005.ODI AND GM WILL REVIEW THAT DATA AND ASSESS THE APPROPRIATENESS OF THE CURRENT SCOPE OF THE RECALL AT THAT TIME.

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.

Tire Size: 265 70 16. While driving on a straight and level highway, the right rear tire sidewall completely shredded. Tire lost all air pressure and separated from the rim. I bought four General Grabber tires in July 2021. This is the second tire that the sidewall shredded. The first one shredded on the left rear side in July of 2024. There are a lot of General Grabber tires being recalled for over-cured sidewalls but it's strange that there are no recalls on this particular tire.

THE FIRST TIME THE ABS EBCU FAILED WE HAD ONLY OWNED THE CAR A FEW YEARS. WE FIGURED OUT SOMETHING WAS WRONG BY THE CONTINUOUS GROWLING BUZZ UNDER THE VEHICLE. WE HAD TO FULL THE FUSE TO DISCONNECT THE UNIT TO PREVENT IT FROM RUNNING DOWN THE BATTERY WHILE WE TRIED TO LEARN EXACTLY WHAT WAS WRONG. ----------- ON THE GOOD SIDE, THE CAR RUNS FINE WITHOUT IT. ON THE BAD SIDE, EBCU REPLACEMENT IS A RIDICULOUSLY EXPENSIVE REPAIR. GM CHARGES $1400 FOR THE STUPID PART, THE TOTAL WAS JUST UNDER $2000 BY THE TIME ALL WAS DONE.----------- IT WOULD BE ONE THING IF THE EBCU WAS SOME GREAT INVENTION THAT REALLY IMPROVED THE HUMAN CONDITION. IT IS NOT. NOT ONLY DOES IT NEVER HELP, IT IS ACTUALLY DANGEROUS.---------- ANY TIME YOU TRY TO STOP ON BUMPY ROADS THE EBCU FIGHTS YOU. MANY TIMES I THOUGHT I WAS GOING TO DRIVE INTO AN ACCIDENT AT AN INTERSECTION BECAUSE THERE WAS A BUMP AND THEN THE STUPID ABS UNIT WOULD NOT LET ME BRAKE. IT FORCES THE BRAKE PEDAL UP AND LETS THE CAR ROLL FORWARD WHEN I AM FRANTICALLY TRYING TO STOP THE CAR.---------- HOW MANY TIMES I HAVE WISHED I DIDN'T HAVE POWER BRAKES AT ALL! ---------- THE REASON I FOUND THIS WEBSITE IS BECAUSE NOW AT 130782 THE STUPID THING HAS FAILED AGAIN. NOW WITHOUT A WARRANTY, BUT WITH THE INTERNET, I LEARNED HOW MANY OTHER PEOPLE HAVE EXPERIENCED THE FAILURE OF THIS UNIT. THERE ARE MANY PAGES ABOUT IT AMONG GM CAR ENTHUSIAST GROUPS, AND EVEN EBAY AUCTIONS OFFERING TO FIX THE THINGS! ---------- THE EBCU IS IN A TIGHT SPOT YOU CAN ONLY GET TO WITH ONE HAND WHILE LYING UNDER THE VEHICLE, AND A QUART OF BRAKE FLUID DRIPS OUT ON YOU AS YOU SEQUENTIALLY UNDO THE 5 BRAKE LINES THAT LEAD TO THE UNIT.---------- MY GENERAL OPINION ABOUT AUTO DESIGN IS THAT WHOEVER APPROVES THE FINAL DESIGN OF SOME PART SHOULD HAVE TO CHANGE ONE OF THEM AT HOME WITH TOOLS COMMONLY AVAILABLE TO AN AVERAGE CITIZEN! *TR

This service bulletin explains how to measure for oil consumption and possible reasons for loss of oil.

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.

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.

This service bulletin advises of a new fuel injection cleaner kit used for decarbonizing the intake valves to correct conditions of rough idle, Crank no start, extended crank or misfire, MIL with DTCs, and explains how Top Tier fuels should be used to reduce carbon build-up.

This bulletin provides information for use on a Product Assistance Claim (PAC), which is formerly known as a Product Allegation Resolution (PAR) claim.

This service bulletin provides information for dealers/technicians on Service Programming System (SPS) Error Codes E4398, E4399, E4401, E4403, M4404, M4413, M6954, M6955, E4414, E4423, E4491, E4492, or E6961 and resolution information.
