2004 GMC ENVOY XUV DIES WHEN IN DRIVE AND STOPPED FOR STOP LIGHT, STOP SIGN, ETC. WHEN THE GAS IS APPLIED, THE CAR DIES AND I TIE UP TRAFFIC WHILE HAVING TO SHIFT TO PARK, RESTART THE ENGINE, AND THEN SHIFT TO DRIVE AND PROCEED THROUGH THE INTERSECTION. IT NEVER DIES WHILE DRIVING, ONLY AT A STOP. I HAVE HAD THIS CAR TO THE DEALER NUMEROUS TIMES AND, BECAUSE THERE IS NO "CODE" , THEY DON'T KNOW WHAT TO DO TO FIX IT. THE CAR ALSO HAS A GAS TANK THAT IS CRACKED AT THE NECK AND CAUSES THE CHECK ENGINE LIGHT TO BE ON ALL THE TIME. THE DEALERSHIP ASSURES ME THAT THIS IS NOT A SAFETY CONCERN NOR DOES THE GAS TANK CRACK HAVE ANYTHING TO DO WITH THE ENGINE DYING. THERE IS NO GAS LEAK BUT AIR DOES GET INTO THE TANK CAUSING THE LIGHT TO STAY ON. THE THROTTLE BODY HAS BEEN CLEANED AND THE ENTIRE EMISSION SYSTEM HAS ALSO BEEN CHECKED AND NO ONE CAN FIGURE OUT WHAT THE PROBLEM IS. DEALERSHIP ALSO SAYS THAT THE GAS TANK PROBLEM IS QUITE COMMON BUT THAT THERE IS NO RECALL..................WHY NOT?????? THE MAIN COMPUTER MODULE WAS REPLACED AND THIS HAS BEEN HAPPENING SINCE THEN. *TR

I HAVE A 2004 GMC ENVOY XUV AND WHEN THE OIL WAS JUST RECENTLY CHANGED THE MECHANIC NOTICED THAT THE GAS TANK WAS LEAKING AT THE POINT WHERE THE FILLER MET THE MAIN BODY OF THE TANK. HE SAID SINCE THE TANK WAS PLASTIC THE GAS WAS CAUSING THE DETERIORATION AND THE ENTIRE TANK WOULD CAUSE A MAJOR ISSUE. AFTER CHECKING WITH OUR LOCAL GMC DEALER I DISCOVERED THAT THE VEHICLE IS JUST OUT OF THE 3 YR WARRANTY PERIOD AND SINCE IT WAS PURCHASED IN ARIZONA AND NOT CALIFORNIA IT IS NOT COVERED UNDER THE EXTENDED GMC WARRANTY. THIS SHOULD NOT BE PART OF A REPLACEMENT PLAN THE CONSUMER SHOULD BE PAYING FOR, NOT LIKE A REGULAR MAINTENANCE ITEM (CHANGING TIRES, OIL CHANGES, SPARK PLUGS, ETC.) CUTTING CORNERS TO MAKE THE VEHICLE LIGHTER AND THEN NOT SUPPORTING THE CHANGE IS NOT THE BEST WAY TO BE POPULAR. *TR

VEHICLE'S "CHECK ENGINE" LIGHT CAME ON 2 DAYS PRIOR TO FAILING A VEHICLE EMISSIONS TEST FOR FUEL TANK LEAK. DEALER STATED THAT THERE WAS A "SPECIAL POLICY" IN PLACE AS THE MANUFACTURER RECOGNIZED THIS SAME DEFECT ON OTHER VEHICLES. THE VIN NUMBER WAS NOT INCLUDED IN THE "SPECIAL POLICY" BUT WAS THE SAME DEFECT. THE DEALER IS ADVISING NOT TO CONTINUE TO DRIVE THE VEHICLE UNTIL REPAIRED. THE DEALER OPINION IS THAT DUE THE "SPECIAL POLICY" THERE ARE NO FUEL TANKS AVAILABLE SO THE VEHICLE IA LOCATED AT THE DEALER UNTIL REPAIRED. OLD PART CAN BE MADE AVAILABLE. *TR

4RQ17002 · Loss Of Headlights
Opened Apr 24, 2017 · Closed Mar 29, 2021
Status: closed (inferred from source dates) · Exterior Lighting:headlights
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.
