2003 GMC Envoy Xl 370

DURING THE COURSE OF THIS EA INVESTIGATION, ODI OBSERVED THAT THE MAJORITY OF THE COMPLAINTS (88%) AND WARRANTY CLAIMS (94%) WERE REPORTED FOR VEHICLES THAT ARE REGISTERED FOR USE IN THE SALT BELT REGION OF THE US.THIS AREA INCLUDES 20 STATES IN THE NORTHEAST, MID ATLANTIC AND THE MIDWEST REGIONS AND THE DISTRICT OF COLUMBIA.CONSUMERS IN THE SALT BELT REGION REPORTED TO ODI THAT THEY COULD SMELL FUEL VAPORS IN THEIR VEHICLES WHILE DRIVING.UPON FURTHER EXAMINATION OF THEIR VEHICLES, THEY DISCOVERED THAT FUEL VAPORS WERE COMING OUT OF THE TOP OF THE FUEL TANK. THIS CONDITION IS CAUSED BY CORROSION OF THE RETURN AND SENDER LINES OF THE FUEL PUMP MODULE.WATER AND ROAD SALT COLLECT ON TOP OF THE FUEL PUMP LEADING TO SMALL PINHOLES APPEARING ON THE FUEL LINES.FUEL MAY LEAK AND COLLECT ON TOP OF THE MODULE AND/OR SPILL ONTO THE GROUND.THE DATA EVALUATED UNDER THIS INVESTIGATION REFLECT A RELATIVELY LOW FREQUENCY OF OCCURRENCE THAT LARGELY ARISES IN SALT BELT STATES.GM HAS EXTENDED THE WARRANTY ON THE SUBJECT COMPONENT TO TEN YEARS OR 120,000 MILES.FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED AT THIS TIME; ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.FOR ADDITIONAL INFORMATION SELECT DOCUMENT SEARCH.

IN JUNE 2007, GM WILL EXPAND ITS SPECIAL POLICY TO ADDRESS FUEL TANK INLET CHECK VALVE (ICV) FRACTURES ON CERTAIN MODEL YEAR (MY) TRAILBLAZER EXT AND GMC ENVOY XL VEHICLES.THE EXPANDED POLICY COVERS MY 2002-2004 TRAILBLAZER EXT, GMC ENVOY XL, AND GMC ENVOY XUV VEHICLES AND WILL EXTEND FOR A PERIOD OF 10 YEARS OR 150,000 MILES (WHICHEVER COMES FIRST).GM WILL PROVIDE FREE REPAIR OF THE FUEL TANK. IT IS SENDING LETTERS TO OWNERS BEGINNING IN JUNE OF 2007.THIS ACTION SUPERSEDES GM'S PREVIOUS 7 YEAR/70,000 MILE SPECIAL POLICY FOR MY 2002 TRAILBLAZER EXT AND ENVOY XL VEHICLES.THE CONDITION IS MOST OFTEN REPORTED AS ILLUMINATION OF THE SERVICE ENGINE SOON (SES) LIGHT.THE VEHICLE'S DIAGNOSTIC SYSTEM DETECTS THE PRESENCE OF A FUEL SYSTEM PRESSURE LEAK AND ILLUMINATES THE SES LIGHT.OTHER OWNERS REPORT SMELLING GASOLINE FUMES. THE ACTION TAKEN BY THE MANUFACTURER IS SUFFICIENT TO RESOLVE THE ISSUES RAISED BY THIS INVESTIGATION.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.

ODI HAS RECEIVED REPORTS THAT THE FUEL PUMP MODULE LEAKS FUEL AND OR VAPOR UNDERNEATH THE VEHICLE.GM STATES, THE FAILURE MECHANISM IS CORROSION OF THE FUEL PUMP MODULE FLANGE WHICH MAY LEAD TO A FUEL LEAK.CORROSION OF THE FUEL PUMP MODULE FLANGE IS THE RESULT OF THE VEHICLE OPERATING IN A CORROSIVE ENVIRONMENT.ODI HAS UPGRADED THIS PE TO ENGINEERING ANALYSIS (EA07-009) TO FURTHER ASSESS THIS ISSUE.

ALL THE ELECTRICAL COMPONENTS GO CRAZY. SPEED-OMETER WORKS WHEN IT WANTS TO JUST LIKE THE BATTERY OIL GAS AND TEMP GAUGE. THE AC AND HEATER HAVE A MIND OF THEIR OWN AS WELL. ALONG WITH ALL THE LIGHTS. SOME TIMES THEY WORK SOMETIMES THEY DONT

GMC IS ADMITTING TO A FAULTY GAS TANK AND ONLY COVERS THIS UP TO 150,000 MILES I BOUGHT THE CAR AFTER THE 150,000 MILES AND NOW HAVE GAS LEAKING THE TANK WAS NEVER FIXED. WHY DOES THE MILEAGE MAKE A DIFFERENCE? THIS IS A MAJOR SAFETY ISSUE THAT GMC SHOULD COVER REGARDLESS OF THE MILEAGE. JUST BECAUSE MY GAS TANK DID NOT LEAK AS SOON AS OTHER ONES DID MEANS I SHOULD NOT BE COVERED? A RECALL IS A RECALL AND THEY SHOULD BE RESPONSIBLE FOR FIXING THE PROBLEM.

MY WIFE WAS IN THE PROCESS OF CLOSING THE REAR HATCH ON OUR 2003 ENVOY XL (80,000 MILES) AFTER REMOVING SOME ARTICLES FROM THE BACK. SHE HAD MOVED THE DOOR ABOUT 1-2 INCHES DOWNWARD USING THE MOLDED HANDLE ON THE BOTTOM OF THE LIFT GATE TO CLOSE THE DOOR WHEN THE REAR GLASS SHATTERED OVER HER HEAD. LUCKILY SHE WAS NOT INJURED BUT WAS COVERED IN SAFETY GLASS. THE GLASS WAS NOT DAMAGED YESTERDAY WHEN I DROVE THE VEHICLE AND UNLOADED SUITCASES FROM THE REAR. AMBIENT TEMPERATURE WAS ABOUT 70 DEGREES. I DID NOTICE THAT THE REAR BRAKE LIGHT ASSEMBLY IS NOW ANGLED UPWARDS IN THE 'GATE RAISED' POSITION, EVEN AFTER CLOSING THE HATCH. ALSO NOTICED THE TOP, RIGHT SIDE RUBBER GROMMET ON THE STAMPED BRACKET ATTACHING THE GLASS IS VERY WORN, ALLOWING SIGNIFICANT MOVEMENT. I PLAN ON TAKING THE VEHICLE TO A DEALER TO DETERMINE ROOT CAUSE IF POSSIBLE AND WILL HAVE THE GLASS AND ALL TOUCH POINTS REPLACED IF POSSIBLE. I HAVE NO CONFIDENCE THAT THIS WILL NOT HAPPEN AGAIN IF THERE IS A DESIGN INTERFERENCE ISSUE WITH THE GLASS AND THE SURROUNDING COMPONENTS THAT HAPPENS OVER TIME. THERE APPEAR TO BE NUMEROUS CASES ON THE AUTOMOTIVE FORUMS WEBSITE REGARDING ENVOY XL REAR HATCH GLASS SHATTERING FOR NO APPARENT REASON (SOME MULTIPLE OCCURRENCES). I AM SURPRISED MORE COMPLAINTS HAVE NOT BEEN REGISTERED TO NHTSA OFFICIALLY (ONLY FOUND ONE-10081011). IT IS ONLY A MATTER OF TIME BEFORE SOMEONE IS SERIOUSLY HURT. I HAVE BEEN A BRAKE ENGINEER FOR 10+ YEARS AND TAKE SAFETY VERY SERIOUSLY. *TR

This PI communicates the requirement to provide a pico file to receive diagnostic assistance from TAC.

This Preliminary Information communication provides information to the technician about changing the tire and wheel size on vehicles. General Motors will only support a tire calibration for tires that have been sized, tested and designed for the vehicle in question and its applications. Technician should not use the information that is provided by the antilock braking system tire size selection.

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.
