MY DRIVER SIDE LOCKS AND WINDOW CONTROLS HAVE CEASED TO OPERATE. EVIDENTLY FLUID MAY ENTER THE DRIVER'S DOOR MODULE, CAUSING CORROSION THAT COULD RESULT IN A SHORT CIRCUIT IN THE DOOR MODULE WHICH CAUSED THE POWER DOOR LOCK AND POWER WINDOW SWITCHES TO BECOME INOPERATIVE. MY CONCERN IS THAT THE SHORT MAY ALSO CAUSE OVERHEATING, WHICH COULD MELT COMPONENTS OF THE DOOR MODULE, PRODUCING AN ODOR, SMOKE, OR A FIRE. I LOOKED ON THE INTERNET AND THERE IS A RECALL FROM GM AND DEALERS WILL INSPECT THE DRIVER'S DOOR MODULE, IF IT IS FUNCTIONING CORRECTLY, A PROTECTIVE COATING WILL BE APPLIED. IF THE MODULE IS NOT FUNCTIONING CORRECTLY, IT WILL BE REPLACED. THE GM RECALL NUMBER IS 12180. I CALLED GM AND THEY TOLD ME THAT ALTHOUGH THIS EXACT PROBLEM IS HAPPENING TO MY AUTOMOBILE...MY CAR IS NOT COVERED. I AM AFRAID THAT MY CAR WILL CATCH ON FIRE. *TR

DRIVING THE VEHICLE ON THE HIGHWAY AT APPROXIMATELY 75MPH, GAS GAUGE WENT COMPLETELY DOWN TO E WITH A FULL TANK. THE NEEDLE WAS BASICALLY READING IN THE SAME POSITION AS WHEN IT IS IN THE OFF POSITION. AFTER THAT HAPPENED THE VEHICLE SPEEDOMETER STARTED READING INCORRECT SPEEDS I WILL BE AT A DEAD STOP AND AT A STOP LIGHT AND MY SPEEDOMETER WILL BE READING 75 MPH STUCK. I KNOW THERE WAS A CLASS ACTION LAWSUIT IN 2007 APPROXIMATELY AND LISTED CERTAIN GM VEHICLES BUT THIS ONE WAS NOT INCLUDED. I THINK THAT GM NEEDS TO LOOK AT THIS AFFECTING OTHER MODELS AND MAKES THEY REPLACED SOME VEHICLES WITH THIS ISSUE AND THE PROBLEM LIES WITH THE STEP MOTOR IN THE CLUSTER GAUGE. IF YOU TAKE THE GM DEALERSHIP THEY WANT TO CHARGE YOU $500 DOLLARS TO REPAIR ON A ISSUE THAT IS BEING REPLACED ON OTHER MODELS. PLEASE PLEASE GET THIS TO BE RECALL THIS IS A ISSUE THAT WILL CAUSE SOMEONE TO GET HURT VERY BAD IN A ACCIDENT. *TR

THIS IS THE SECOND OCCURRENCE OF AN ISSUE WITH THE VEHICLES MANUAL SWITCH FOR 2HI,AWD,4HI,4LOW. THE DEALER I BOUGHT THE USED VEHICLE FROM FIXED THE ISSUE RIGHT AFTER PURCHASE AND I'M HAVING ANOTHER PROBLEM WITH THE SWITCH. I TRY TO SELECT ANYTHING BESIDES 2HI AND THE SELECTOR WILL JUST CONTINUE TO BLINK ON THE SELECTION WITHOUT ANY ACTION. SOMETIMES THE SERVICE 4WD WILL ILLUMINATE ON THE DASH.

I GOT HOME ONE EVENING AND WHEN I TURNED THE IGNITION KEY TO SHUT THE TRUCK OFF THE ENGINE CONTINUED TO RUN. I WAS CONCERNED; AS I COULD NOT LEAVE THE VEHICLE RUNNING ALL NIGHT; AT THAT POINT I TRIED TO ENGAGE THE KEY AGAIN AND THE VEHICLE WAS STILL RUNNING . I BECAME CONCERNED AND STARTED TO FIDDLE WITH THE KNOBS AND WAS SURPRISED WHEN AFTER TURNING THE HIGHLIGHT SWITCH THE ENGINE SHUT OFF. THE NEXT MORNING I HESTITATELY ATTEMPTED TO START THE VEHICLE AND WHEN I WAS SUCCESSFUL I HEADED STRAIGHT TO THE GMC DEALER. THE DEALER SAID THAT IT WAS A WIRING PROBLEM AND THE IGNITION WIRING HAD TO BE REDONE; (THE COST WAS $1600.00) I STARTED A DIALOG WITH GM AND THEY ENGAGED ME WITH SEVERAL CONVERSATIONS; WHICH LED ME TO BELIEVE THAT THEY WOULD PICK UP THE COST; AS ELECTRICAL COMPONENTS WERE NOT PART OF ANY SCHEDULED MAINTENANCE THAT I AS A OWNER WOULD BE RESPONSIBLE FOR. WHEN I MADE A REQUEST FOR REIMBURSEMENT I WAS TOLD THAT BECAUSE OF THE MILEAGE THERE WAS NOTHING THEY COULD (OR WOULD DO). I COULD SEE IF IT WERE RELATED TO AN OIL CHANGE. BRAKES,FILTERS,ETC. BUT AS A OWNER THIS ITEM IS OUTSIDE OF MY AREA OF RESPONSIBILITY. GM SHOULD STAND BEHIND THEIR PRODUCTS AND MAKE ME AND OTHERS WHOLE. PS. *TR

MY GOLDEN RETRIEVER/DOG COULD HAVE BEEN CHOKED BY THE ELECTRIC WINDOW CONTROL AS SHE STANDS ON THE ARMREST WITH HER HEAD OUT THE HALF OPEN WINDOW. INSTEAD, WE WERE VERY LUCKY IN THAT THE WINDOW OPENED ALL OF THE WAY INSTEAD AND SHE DIDN'T FALL OUT. THIS WINDOW CONTROL IS THE TOGGLE TYPE, PRE THE SAFETY ONES.

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

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.

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.
