2002 GMC Envoy Xl

The subject vehicles are model year (MY) 2002-2009 Chevrolet Trailblazer, GMC Envoy, 2004-2007 Buick Rainier, 2003-2008 Isuzu Ascender, 2005-2009 Saab 9-7X, 2002-2004 Oldsmobile Bravada, 2003-2006 Chevrolet SSR, 2005-2009 Buick Lacrosse, and 2006-2008 Pontiac Grand Prix. This scope includes the Trailblazer/Envoy variants: 2002-2006 Envoy XL/Trailblazer EXT and 2004-2005 Envoy XUV. The original scope of this investigation was expanded to include all vehicles equipped with the subject Headlight Driver Module (HDM). The focus of the investigation was to determine whether actions performed by General Motors adequately addressed any unreasonable risk to motor vehicle safety in the subject vehicles concerning the headlights and the HDM that controls them.Under normal electrical load and environmental conditions, the HDM can overheat inside the Underhood Electrical Center (UEC). This can cause the module to fail and result in a simultaneous loss of both low beam headlights and both daytime running lights (DRLs), often with no warning or prior detectability to the driver. This failure can be intermittent or permanent. No other exterior lights are affected. High beams, turn signals, brake lights, and reverse lights are still operational.General Motors addressed this issue with 2 recalls (14V755 & 15V519) and a special coverage program (N172091910). In view of the recalls and special coverage program implemented by GM and the vehicle high beams continuing to operate, ODI has tentatively concluded that the actions taken by GM mitigate any unreasonable risk to safety posed by HDM failure in the subject vehicles.Accordingly, the investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency reserves the right to take additional action if warranted by new circumstances.The ODI reports cited above are available for review online at NHTSA.gov under the identification numbers in the attached document.

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.

IVE NOTICE MY FRONT HEADLIGHTS HAVE BEEN GETTING WORSE FOR ME TO SEE AT NIGHT. I DON'T SEE WHATS IN FRONT OF ME WHILE DRIVING AT THE LAST MINUTE,ANYTIME AT NIGHT WHILE DRIVING I DON'T SEE TURNS, OBJECTS AND OTHER THINGS TILL THE LAST SECOND.

AS I WAS DRIVING DOWN INTERSTATE AT 70-75MPH , THE HEADLIGHTS, DASH LIGHTS, ALL THE LIGHTING JUST SHUT OFF! I HAD NO IDEA WHAT TO DO. I WAS ON ONE OF THE MOST DANGEROUS INTERSTATES, KNOWN FOR FATAL ACCIDENTS... AND I'M DRIVING IN THE DARK WITHOUT LIGHTS! I QUICKLY MOVED TO SIDE OF ROAD AND SHUT IT OFF IN CASE OF FAULTY WIRING/FIRE HAZARD. AFTER APPROX. A FIVE MINUTE PHONE CALL, I STARTED CAR, LIGHTS WORKED. STARTED DRIVING AGAIN, APPROX. 10 MINUTES DOWN ROAD, LIGHTS SHUT OFF AGAIN. I HOPE THIS PROBLEM IS RESOLVED SOON! THIS IS DANGEROUS AND CAN KILL PEOPLE! *TR

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

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.
