2004 GMC Envoy Xuv

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.

BY LETTER DATED APRIL 29, 2005, GM NOTIFIED THE AGENCY THAT IT IS CONDUCTING ASAFETY RECALL ( NHTSA RECALL NO. 05V198 ) INVOLVING CERTAIN MODEL YEARS (MY) 2003-2004 ISUZU ASCENDER, CHEVROLET TRAILBLAZER, GMC ENVOY, OLDSMOBILE BRAVADA AND MY 2004 BUICK RAINER VEHICLES.THE RECALL APPLIES TO VEHICLES BUILT FROM APRIL 2003 THROUGH NOVEMBER 2003 FOR A TOTAL VEHICLE POPULATION OF 286,478.GM REPORTS THE DIRECTIONAL/HAZARD SIGNALS FAILURE IS DUE TO STICKING CONTACTS ON ROUTING RELAYS IN THE FLASHER MODULE.GM WILL REPLACE THE FLASHER MODULE ON ALL INVOLVED VEHICLES.BASED ON GM'S SAFETY RECALL ACTION, THIS INVESTIGATION IS CLOSED.

THE THIRD BRAKE LIGHT CONNECTIONS LOCATED IN THE REAR TAILGATE ARE SEVERELY CORRODED AND WILL NOT LIGHT UP WHEN BRAKING. THIS CONDITION DOES NOT ALLOW PASSING OF STATE INSPECTION. THE ENTIRE BRAKE LIGHT ASSEMBLY AND WIRE HARNESS MUST TO REPLACED TO PASS STATE VEHICLE INSPECTION. THIS CONDITION IS CONTINUOUS, WHEN PARKED, WHEN DRIVING (WE FOLLOWED IT AROUND THE BLOCK TO SEE IF IT JIGGLED ON), I HAVE NOTHING TO UPLOAD BECAUSE THE BRAKE LIGHT WILL NOT LIGHT UP.

2004 ENVOY XUV, IMPECCABLY MAINTAINED, CAR WAS PARKED IN MY DRIVE WAY AND I STARTED IT TO GO TO THE STORE AND IT STARTED CHUGGING AND THEN ALMOST DIED, BUT THEN WENT BACK TO NORMAL BUT THE SERVICE ENGINE SOON AND REDUCED ENGINE POWER LIGHTS ILLUMINATED ON DASH.TURNED OFF ENGINE. RESTARTED, AND THE SERVICE ENGINE SOON LIGHT WAS STILL THERE SO MY HUSBAND HOOKED UP HIS CODE READER AND IT HAD THE CODE P1680 ( THROTTLE BODY POSTIONING CENSOR.) AND THIS ISN'T THE FIRST TIME IT'S DONE IT BUT THE ENGINE LIGHT HAS ALWAYS JUST FLASHED IT WOULD NEVER STAY ON SO WE COULD READ THE CODE. BUT IN ORDER TO FIX THIS YOU HAVE TO BUY A WHOLE NEW THROTTLE BODY HOUSING BECAUSE THE CENSOR IS BUILT INTO IT. AND IT ISN'T CHEAP. AT AUTOZONE IT IS $280.00. AND YOU HAVE TO ALSO BUY A GASKET FOR IT AND NEW INTAKE MANIFOLD GASKETS BECAUSE TO REMOVE THE THROTTLE BODY HOUSING WHICH IS CONNECTED TO THE MANIFOLD YOU HAVE YO REMOVE THE MANIFOLD ALSO. HOW IN THE WORLD DOES GM EXPECT US TO BE ABLE TO FIX THIS ISSUE IF IT'S ALWAYS SO MUCH MONEY FOR PARTS FOR THESE CARS. AND I ALSO HAVE ISSUES WITH MY BACK TAILGATE AND BOTH BIG WINDOW MOTORS. I HAVE REPLACED ONE BUT STILL SAVING UP TO REPLACE THE MIDDLE ONE AND I'VE ALSO HAD ISSUES WITH MY GAS TANK WHICH IS $677.00 OR MORE AT THE DEALERS FOR A NEW GAS TANK BECAUSE U CAN'T JUST FIX THE FILLER HOSE. SUCH FAILURES WILL EVENTUALLY KILL SOMEONE. SO I THINK GMC NEEDS TO TAKE A LONGER LOOK AT THESE GMC ENVOY XUVS AND GET SOME RECALLS OUT TO FIX THESE DANGEROUS PROBLEMS. AND HONOR ALL CARS THAT COME IN NO MATTER WHAT. BECAUSE WE HAD TO FIX THE GAS TANK ISSUE OURSELVES BECAUSE WE COULD NOT AFFORD TO BUY A NEW GAS TANK.

STARTED SMELLING GAS, STARTED DRIPPING FUEL. AFTER INVESTIGATING THE FUEL LINES COMING OUT OF THE FUEL PUMP WERE SEVERELY CORRODED AT THE TOP OF THE GAS TANK. DRIPPING GAS COULD HAVE CAUGHT FIRE. LEARNED THERE WAS A TSB ON THIS AND EXTENDED WARRENTY DUE TO CORROSION OF FUEL LINES. THE WARRENTY WAS FOR 10 YEARS OR 150K. THE VEHICLE IS NOW 11 YEARS OLD. I HAVE LIVED IN THE SAME HOUSE FOR EIGHT YEARS AND NEVER RECEIVED A RECALL OR TSB NOTICE FROM GMC. OVER 800$ FOR A NEW FUEL PUMP AND TO DROP GAS TANK FOR REPAIRS. WHILE THE VEHICLE IS A 2004 IT ONLY HAS 67K ON IT.

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.
