DOUBLE FAILURE OF 4-WHEEL DRIVE INDICATORS. 4-WHEEL DRIVE FAILED BUT THE "SERVICE LIGHT" DID NOT APPEAR ON THE DASH AND THE LED LIGHT ON THE 2WD/AWD/4-HI/4-LO SWITCH DID NOT DISPLAY CORRECTLY. BECAUSE WE WERE UNAWARE THAT BOTH INDICATORS WERE NOT WORKING AND THE 4-WHEEL DRIVE WAS NOT WORKING WE ATTEMPTED TO GO OVER A MOUNTAIN PASS DURING SNOW CONDITIONS UNDER THE ASSUMPTION THAT THE 4-WHEEL DRIVE WAS WORKING CORRECTLY. I WAS BRINGING MY MOTHER HOME FROM THE HOSPITAL AFTER A HEART PROCEDURE. LUCKILY I WAS DRIVING CAREFULLY, BECAUSE THE VEHICLE DID BEGIN TO LOSE CONTROL, BUT I WAS ABLE TO MAKE THE NECESSARY CORRECTIONS. WE WERE FORCED TO TURN AROUND AND TAKE ANOTHER ROUTE, WHICH DOUBLED THE LENGTH OF OUR DRIVE. THIS NORMALLY WOULD NOT BE A PROBLEM EXCEPT FOR MY MOTHER'S CONDITION. *NM

AS I AM GOING DOWN THE ROAD THE TACHOMETER STARTS TO JUMP AROUND AND THEN I LOSE THE DIRECTIONALS AND MY LIGHTS. IF I TURN OFF THE IGNITION IT WILL NOT START AGAIN. THIS HAS HAPPENED FOUR TIMES IN THE PAST YEAR. THE DEALERSHIP TELLS ME THAT FUSE #22 IS BLOWING. AS OF TODAY, MY TRUCK IS STILL AT THE DEALERSHIP AND THEY DO NOT KNOW WHAT IS CAUSING IT. THEY HAVE REPLACED THE FUSE EACH TIME. THEY ALSO REPLACED THE INSTUMENT CLUSTER AND THE IGNITION LOCK. I AM SEEKING LEGAL ADVISE.

NEXT CAME THE TAILLIGHT RECALL. NOW I HAVE A RECURRING PROBLEM WITH A DEAD BATTERY. THIS DOESN'T HAPPEN ALL THE TIME AND NOTHING HAS BEEN LEFT ON TO CAUSE IT. I CAN GO INTO A STORE AND COME OUT TO FIND IT DEAD. WHEN YOU CHARGE THE BATTERY, THEN EITHER THE HEATED SEATS WORK IMPROPERLY, THE BLOWER WON'T COME ON, SOMETHING DIFFERENT EVERY TIME. *JB

WENT OUT TO START VEHICLE ON SEPTEMBER 18, 2004 - TUNED KEY AND NOTHING HAPPENED, NO STARTER MOTOR, NO DASHBOARD LIGHTS, NOTHING. KEY REMIANED LOCKED IN STEERING COLUMN, COULD NOT BE REMOVED. TRIED AGAIN THE NEXT MORNING (9/19) - SAME THING. TRIED AGAIN THE NEXT MORNING (MONDAY, 9/20). THE SAME THING - AT THAT POINT CALLED DEALER TO TOW VEHICLE. ABOUT 3 HOURS LATER THE TOW TRUCK CAME - TOW TRUCK OPERATOR GOT IN VEHICLE TURNED KEY - AND VEHICLE STARTED RIGHT UP JUST AS IF NOTHING WAS EVER WRONG! . STILL HAD VEHICLE TOWED TO DEALERSHIP - DEALER CHECKED BEHICLE OVER AND FOUND NOTHING WRONG. ON SATURDAY, OCTOBER 23RD, CAME OUT OF BANK AFTER RUNNING ERRNAD, TURNED KEY IN VEHICLE - NOTHING HAPPENED AGAIN. KEPT TURNING KEY OFF AND ON FOR ABOUT 10 MINUTES UNTIL VEHICLE STARTED OUT OF THE BLUE. DROVE STRAIGHT TO DEALER. DEALER REPLACED IGNITION SWITCH. VEHICLE WORKED FINE UNTIL SUNDAY, JANUARY 23RD. WENT TO START VEHICLE AND ONE AGAIN, NOTHING HAPPENED, NO LIGHTS, NO STARTER - NOTHING. KEY ALSO LOCKED IN STEERING COLUMN. DEALER TOWED VEHICLE THE NEXT DAY. DEALER COULD FIND NOTHING WRONG, THEORIZED AN INTERIOR LIGHT WAS LEFT ON (BUT I KNOW IT WASN'T). DEALER REPLACED SOME ENGINE FAN THEY THEORIZE WAS TURNING ON AFTER ENGINE TURNED OFF AND DRAINING BATTERY - I TOLD THEM THAT'S FINE BUT DOESN'T EXPLAIN WHY TRUCK WILL START DAYS AFTER AN INITIAL FAILURE. THIS INTERMITTENT FAILURE IS FRIGHTENING AS IT SEEMS TO BE A POSSIBLE PART OF A LARGER SYSTEM FAILURE - AS NOTED ON THIS WEBSITE BY OTHER OWNERS - WHEN THE TRAILBLAZER WILL FAIL AT HIGH SPEEDS ON THE HIGHWAY.

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.

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.
