THE GAS TANK ON MY 2003 GMC ENVOY XLT (80K MILES) IS LEAKING, ESPECIALLY WHEN TANK IS FULL. THERE WAS A SMALL PUDDLE ON THE DRIVEWAY. THE PROBLEM ACTUALLY STARTED BACK AROUND 50K MILES WITH ENGINE LIGHT ON. I HAVE TAKEN IT TO DEALER AND MECHANICS BEFORE, BUT IT WAS THOUGHT TO BE SOME SORT OF FUEL CAP PROBLEM OR OVER SENSITIVE SENSORS. HOWEVER, TODAY, BECAUSE MY GAS TANK WAS FULL, THE DEALER FOUND THAT THERE ARE LEAKS CAUSED BY A CRACK TANK AND FUEL TANK NECK. THE FUEL LEAK AND VAPOR ARE SO STRONG THAT I FEARED A SMALL SPARK CAN SET THE WHOLE VEHICLE ON FIRE LIKE A ROMAN CANDLE. CAR WAS USED FOR EVERYDAY COMMUTE ONLY. *TR

MY SERVICE ENGINE LIGHT CAME ON AND THEN I STARTED DETECTING A ODOR OF GASOLINE. THE ORDER GREW STRONGER AND THEN I GOT THE "SPECIAL NOTICE", BUT NOT A RECALL ABOUT THE CORROSION IN THE FUEL TANK. WHEN I TOOK THE CAR INTO THE DEALER, I WAS TOLD THAT THIS WAS NOT THE PROBLEM AND THAT IT WAS A CRACK AT THE FILLER PIPE ON THE GAS TANK AND THAT THIS WAS NOT COVERED. I ASKED WHAT COULD CAUSE THIS AND THEY COULD NOT GIVE ME AN ANSWER. MY CAR ONLY HAS 49,000 MILES AND IS IN EXCELLENT SHAPE, EXCEPT FOR ALL THE RECALL ITEMS. I BELIEVE THAT GMC SHOULD FIX THIS PROBLEM, NOT ONLY IT IS COSTLY TO FIX, BUT IT IS VERY DANGEROUS TO BE DRIVING LIKE THIS. AND READING THE COMPLAINTS, IT SOUNDS LIKE SEVERAL OTHERS HAVE THE SAME ISSUE. *TR

IT ALSO STATES THAT GM WOULD BE SENDING LETTERS TO OWNERS BEGINNING IN JUNE OF 2007 REGARDING THIS "SPECIAL POLICY". I DID NOT RECEIVE SUCH A LETTER. I CONTACTED GM TODAY AT 866-996-9463 REGARDING THIS "SPECIAL POLICY", AND THIS IS THE ANSWER I RECEIVED. SINCE I WAS NOT GRANTED SUCH A LETTER, AND GM DID NOT INCLUDE MY VIN # AS PART OF A SELECTED VIN# MAILING FOR THIS RECALL, I AM NOT ELIGIBLE FOR REIMBURSEMENT OF THE MONIES SPENT TO REPLACE THE GAS TANK. MY COMPLAINT IS THIS: MY VEHICLE FITS WITHIN THE GUIDELINES, MEANING THE MAKE, MODEL, YEAR, AND DESCRIPTION OF DEFECT EXACTLY MATCHES THAT OF WHAT GM CLAIMS TO BE RECALLING, BUT SINCE MY VIN # WAS NOT SELECTED AS PART OF THE "LOT" OF VIN # GM DECIDED TO SEND LETTERS TO, I AM NOT ELIGIBLE. THAT IS NOT A ACCEPTABLE REASON FOR NOT REIMBURSING MY EXPENSES. *TR

TOOK MY 2003 GMC ENVOY TO MY LOCAL GARAGE BECAUSE THE CLUTCH FAN WOULD NOT SHUT OFF. MECHANIC ASKED ABOUT THE STRONG SMELL OF FUEL, AND I SAID I WAS AWARE THE TANK NEEDED TO BE REPLACED DUE TO A CRACK WHERE THE FILL TUBE GOES INTO THE TANK. THE MECHANIC SAID BOTH ARE IMPORTANT TO FIX, BUT THE FUEL LEAK COULD BE A DEADLY SITUATION, AND HE WOULD SUGGEST TACKLING THAT DEFECT FIRST, BUT IN ORDER FOR CAR TO RUN NORMAL HAD TO HAVE CLUTCH FAN REPLACED TOO. TOTAL COST FOR TANK RELATED REPLACEMENT: $1,058.04. TOTAL COST FOR CLUTCH FAN REPLACEMENT: $719.50 TOTAL COST FOR TAXES: $72.75. WHY HAVEN'T THESE WELL KNOWN DEFECTS BEEN ADDRESSED IN A RECALL. THESE ARE NOT INEXPENSIVE REPAIRS WE ARE TALKING ABOUT HERE, NOT TO MENTION THE POTENTIALLY DEADLY CONSEQUENCES GMC IS SUBJECTING THEIR CONSUMERS TO. *TR

Official recalls
3Oct 27, 2005
CERTAIN SPORT UTILITY VEHICLES HAVE A REAR SIDE CLOSURE LATCH THAT MAY NOT LATCH OR UNLATCH DUE TO CORROSION CAUSED BY ROAD SPLASH, SUCH AS WATER AND ROAD SALT. THESE VEHICLES WERE ORIGINALLY SOLD IN OR CURRENTLY REGISTERED IN THE FOLLOWING STATES: CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WEST VIRGINIA, WISCONSIN, AND THE DISTRICT OF COLUMBIA.
Consequence & remedy
Consequence: IF THE DOOR IS NOT LATCHED PROPERLY AND IT GOES UNNOTICED, IT MAY OPEN WHILE THE VEHICLE IS IN MOTION. IF AN UNBELTED OCCUPANT FELL OUT OF THE VEHICLE, PERSONAL INJURIES COULD OCCUR.
Remedy: DEALERS WILL INSTALL A SEAL ALONG THE LOWER PART OF THE ROCKER PANEL TO PREVENT INTRUSION OF CORROSIVE MATERIAL, AND INSPECT THE REAR SIDE CLOSURE LATCHES. FUNCTIONAL LATCHES WILL BE CLEANED AND LUBRICATED. NON-FUNCTIONING LATCHES WILL BE REPLACED. THE RECALL BEGAN ON FEBRUARY 24, 2006. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, OR ISUZU AT 1-800-255-6727.
Nov 1, 2004
ON CERTAIN SPORT UTILITY VEHICLES, VIBRATION AND HEAT MAY CAUSE THE TAIL LAMP/STOP LAMP BULB TO LOOSEN IN ITS SOCKET. IF THIS OCCURS, THE BULB MAY FLICKER AND EVENTUALLY BECOME INOPERATIVE.
Consequence & remedy
Consequence: AN INOPERATIVE BRAKE LAMP WILL NOT CONVEY THE DRIVER'S INTENTION OF STOPPING TO DRIVERS IN FOLLOWING VEHICLES, AND AN INOPERATIVE REAR TURN SIGNAL LAMP WILL NOT CONVEY THE DRIVER'S INTENTION TO TURN TO DRIVERS IN FOLLOWING VEHICLES. BOTH OF THESE FAILURES CAN INCREASE THE RISK OF A CRASH.
Remedy: DEALERS WILL INSPECT THE TAIL LAMP/STOP LAMP ASSEMBLIES, AND IF NECESSARY, REPLACE THEM. THE RECALL BEGAN ON NOVEMBER 22, 2004. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438, OLDSMOBILE AT 1-800-630-6537, BUICK AT 1-866-608-8080, OR GMC AT 1-866-996-9463.

CERTAIN SPORT UTILITY VEHICLES HAVE WINDSHIELD WIPER SYSTEMS THAT WILL NOT TURN ON, CEASE OPERATION WHILE IN USE, FAIL TO TURN OFF/ON BY THEMSELVES (MOISTURE SENSITIVE WIPER SYSTEM), OR HAVE CONTINUOUS WINDSHIELD WASHER PUMP OPERATION BECAUSE THE PRESENCE OF WATER WITHIN THE WIPER MODULES CAN EITHER CAUSE A SHORT CIRCUIT OR CAN LEAD TO THE CORROSION OF COMPONENTS WITHIN THE MODULE.
Consequence & remedy
Consequence: DEPENDING ON THE OCCURRENCE AND WEATHER SITUATION, DRIVER VISIBILITY COULD BE REDUCED, WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS WILL COVER THE WINDSHIELD WIPER MODULE VENT HOLE WITH A PATCH. ALSO, THE WIPER MOTOR, CIRCUIT BOARD, AND ELECTRICAL CONNECTOR WILL BE INSPECTED TO SIGNS OF WATER INTRUSION AND/OR CORROSION AND BE REPLACED AS REQUIRED. THE RECALL BEGAN JULY 6, 2004. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438; OLDSMOBILE AT 1-800-630-6537; OR GMC AT 1-866-996-9463.

6RQ17002 · 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.
