TO WHOM IT MAY CONCERN. 8/29/2012. I BOUGHT A USED 2003 GMC ENVOY XL SLE/SLT AND PURCHASED THE VEHICLE FROM SHERMAN OF SKOKIE IL. ABOUT THIS VEHICLE. THE THIRD BRAKE LIGHT PIECE THAT COVERS THE TOP OF THE REAR WINDOW BASICALLY FELL OFF THE CAR ON A WINDY DAY. THE PLASTIC PIECE THAT HOLDS THE THIRD BRAKE LIGHT BROKE LEADING TO THE ENTIRE PIECE FALLING OFF HANGING BY THE 2 WIRES THAT CONNECT FOR POWER. I LIVE IN ALGONQUIN IL AND RECENTLY HAVE SEEN THREE OTHER ENVOYS WITH THE SAME MISSING THIRD LIGHT PIECE IN A PERIOD OF TWO WEEKS. I HAVE LOOKED UP RECALLS FOR THIS VEHICLE BUT SURPRISINGLY HAVE FOUND NONE. KNOWING I HAVE PERSONALLY SEEN SEVERAL ENVOYS WITH THE SAME MISSING THIRD LIGHT PIECE I THINK THERE NEEDS TO BE A RECALL. NOT ONLY IS THIS A SAFETY HAZARD BUT IT'S THE LAW TO HAVE A THIRD BRAKE LIGHT IN ILLINOIS. I HAVE NOT BROUGHT TO A DEALER SINCE THERE WAS NOT A RECALL AND I DO NOT HAVE THE OUT OF POCKET CASH TO PAY FOR THIS TO BE FIXED. RESPECTFULLY I WOULD LIKE THIS THIRD BRAKE LIGHT PIECE REPLACED AND FIXED AT NO COST TO ME. I DO HAVE THE THIRD LIGHT PIECE THAT FELL OFF TO GIVE BACK TO YOU SO YOU CAN INSPECT IT. I WOULD LIKE THIS FIXED WITHIN 30 DAYS OF RECEIVING THIS LETTER. I WOULD APPRECIATE YOUR PROMPT RESPONSE TO THIS SAFETY HAZARD AND THANK YOU FOR YOUR TIME. THIS IS THE LETTER I SENT GMC AND THEY SAID THERE IS NOTHING THEY CAN DO! *TR

IT'S SEEMS CRAZY TO ME THAT THIS AGENCY THAT WAS CREATED TO PROTECT CONSUMERS FROM FAULTY VEHICLES CAN LET SO MANY COMPLAINTS AGAINST THIS MANUFACTURER THAT WAS BAILED OUT BY TAXPAYERS MONEY CAN BE SO BLIND TO THE GROSS NEGLIGENCE ON GMC PART. I HAVE SPENT COUNT LESS HOURS AND WAY TOO MUCH MONEY ON THIS VEHICLE, ONLY TO FIND OUT THAT MANY OTHER CONSUMERS ARE REPORTING THE SAME PROBLEMS. I HAVE LITERALLY SAT DOWN AND CRIED VOWING NEVER TO BY ANOTHER AMERICAN MADE CAR BECAUSE THEY ARE PIECES OF JUNK (AND THAT IS PUTTING IT NICELY). I HAVE PAID TO REPLACE THE OXYGEN SENSOR AND ALL THAT GOES WITH THAT; THE CATALYST CONVERTER TWICE; THE ELECTRICAL SYSTEM THROUGHOUT THE VEHICLE AND NOW MY RADIO DOESN'T WORK BECAUSE THERE IS A SHORT THAT IS DRAINING THE BATTERY WHEN THE CAR IS TURNED OFF; THE SPEED CONTROL (MPH/RPM) DOESN'T WORK AND I ONLY PRAY THAT I'M NOT SPEEDING WHILE I'M DRIVING; THE REAR WIPER BLADE WORKS WHEN IT FEELS LIKE IT; MY CAR INTERIOR CONSTANTLY SMELLS LIKE GASOLINE AND WHEN I'M FILLING UP MY TANK IT THERE IS ALWAYS SPILLAGE; MY SES LIGHT CONSTANTLY STAYS ON AND SINCE MY STATE PRACTICES EMISSION CONTROL I HOLD MY BREATH AND PRAY THAT I PASS THE TEST SO I CAN LEGALLY DRIVE MY CAR. THESE ARE JUST SOME OF THE PROBLEMS THAT I FACE WITH THIS CAR AND FRANKLY THIS YEAR I'M NOT WORKING SO COMING UP WITH THE MONEY TO PAY AGAIN TO HAVE A MECHANIC REMOVE THE SES LIGHT SO I CAN GO HAVE THE EMISSION TESTING PERFORMED IS RIDICULOUS AND DRAINING A WALLET THAT IS VERY MUCH EMPTY. MY CAR NOW HAS MORE MILEAGE & I HAVEN'T HEARD MY RADIO IN OVER 2 YEARS BECAUSE THEY DON'T KNOW WHAT IS WRONG SO THEY JUST DISCONNECTED IT. WHY HAVEN'T THE NHTSA/DOT REQUIRED GMC TO FIX WHAT THEY KNOW IS BROKEN AND A HAZARD ON THE ROADS? I WOULD STRONGLY RECOMMEND THAT THE NHTSA TAKE THIS SERIOUSLY BEFORE SOMEONE LOSES CONTROL AND PEOPLE LIVES ARE LOST. DON'T LET THIS BECOME ANOTHER TOYOTA ISSUE. *TR

(2003 GMC ENVOY XL) I HAVE RECENTLY FOUND THAT MY WIFE AND KIDS HAVE BEEN RIDING AROUND IN A VEHICLE THAT WAS AN EXPLOSION WAITING TO HAPPEN. GENERAL MOTORS HAS EXTENDED THEIR WARRANTY ON FUEL TANK ISSUES 3 TIMES BECAUSE OF A FLAWED DESIGN. I HAD NO KNOWLEDGE OF THIS BEFORE PURCHASING, AS I BELIEVE I AM THE SECOND OWNER OF THIS VEHICLE. I HAVE SINCE SEEN THAT THIS ISSUE HAS BEEN BROUGHT TO YOUR ATTENTION BUT NOT TO THE MAGNITUDE TO WHICH IT IS OCCURRING. I WONDER IF SOMEONE HAS TO DIE A FIERY DEATH BEFORE THIS ISSUE IS ADDRESSED SERIOUSLY ? I HAVE COMPILED MANY ACCOUNTS OF CUSTOMERS COMPLAINING OF THIS ISSUE AND HAVE RECORDS TO SHARE. I HAVE CONTACTED GM CUSTOMER SUPPORT, ONLY TO BE PUT ON HOLD FOR A TOTAL OF 153 MINUTES IN THE REALM OF 4 CALLS WITH NO RESOLUTION. THIS ENGINEERING FAILURE CONSIST OF GREAT NUMBERS STILL ON THE ROAD. UNLUCKY ONES LIKE MYSELF WILL NOT HAVE ANY KNOWLEDGE OF THIS UNTIL TOTAL FAILURE OCCURS AND AT THAT TIME GM'S POOR DESIGN BECOMES THE BURDEN OF THE CURRENT OWNER. I NEED HELP UNDERSTANDING HOW SUCH A SAFETY RISK CAN BE SWEPT UNDER THE RUG WITH 493,579 OF THESE VEHICLES BEING SOLD. I HAVE FOUND THAT THE DESIGN WAS SO BAD THAT AFTERMARKET SUPPLIERS DO NOT EVEN OFFER THIS TANK. THE ONLY PLACE TO GET ONE IS FROM GM DEALER AT A PRICE OF $650.00, WHICH IS EXORBITANT FOR A PIECE OF PLASTIC. I NEED HELP WITH THIS MATTER BUT IT'S NOT JUST ABOUT ME, YOUR ACTIONS COULD SAVE SOMEONE'S LIVES ! *TR

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.

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.
