CHEVROLET TRAILBLAZER EXT WAS TOWED FROM HIGHWAY DUE TO A RUPTURED TRANSMISSION LINE. TOW TRUCK DRIVER TOWED VEHICLE FROM THE REAR WHEELS. UPON DELIVERING VEHICLE TO REPAIR SHOP, THE ENTIRE UPPER HATCH TRIM MOLDING (HIGH MOUNT BRAKE LIGHT COVER) PIECE AND THE HIGH MOUNT BRAKE LIGHT ASSEMBLY WAS MISSING WITH ONLY THE TWO WIRES DANGLING. UPON INSPECTION, THE PIECE IS ONLY HELD ON THE VEHICLE BY 2 BOLTS AND DOUBLE SIDED TAPE. THE DOUBLE SIDED TAPE ON THE REAR GLASS WAS DRY AND CRUMBLING (COMPLETELY INEFFECTIVE). SINCE THE VEHICLE WAS TRAVELING BACKWARDS BEHIND THE TOW TRUCK, THE PIECE WAS NOT ABLE TO WITHSTAND THE FORCE OF WIND WHICH PUSHED THE PIECE UPWARD UNTIL IT ULTIMATELY CRACKED AND BROKE OFF THE VEHICLE. THERE HAVE BEEN MANY REPORTS OF THIS PIECE FALLING OFF FROM TRAILBLAZER MODELS GOING FORWARD AND GM HAS DONE NOTHING TO REDESIGN OR FIX THE PROBLEM. A LARGE PLASTIC PIECE SUCH AS THAT SHOULD NOT USE 2 BOLTS AND DOUBLE SIDED TAPE AS A PRIMARY MEANS OF ATTACHMENT. AT A MINIMUM, A SAFETY NOTICE SHOULD BE SENT THAT TOWING A TRAILBLAZER FROM THE REAR AT HIGH SPEEDS MAY RESULT IN THIS PIECE BREAKING OFF, POSING A REAL SAFETY CONCERN (FLYING HIGHWAY DEBRIS) TO THE FOLLOWING VEHICLE(S). PARTS ARE FALLING OFF VEHICLES AND NO ONE BUT THE DISGRUNTLED OWNERS SEEM TO CARE. *TR

DESIGN FLAW OF THE CENTER HIGH MOUNTED STOP LAMP APPLIQUE (AKA - REAR UPPER LIFTGATE MOLDING) DURING THE WINTER MONTHS, ICE AND SNOW BUILDS UP BEHIND THE MOLDING, AND WHEN THE USER ATTEMPTS TO OPEN THE LIFTGATE, THE MOLDING IS SEPARATED FROM THE VEHICLE, SOMETIMES RESULTS IN PERMANENT BREAKAGE OF THE MOLDING, OR EVEN SHATTERING OF THE REAR WINDOW. THIS IS A PROBLEM THAT THE COMPANY IS ALREADY AWARE OF, AS EVIDENCED BY A RELEASED TSB. AS EVIDENCED BY NUMEROUS REPORTS ON "TRAILVOY.COM", MANY GROUP MEMBERS HAVE REPORTED HAVING THIS EXACT PROBLEM. I HAVE READ REPORTS OF THIS PIECE MYSTERIOUSLY COMING OFF, TO THE SURPRISE OF THE DRIVER, WHILE DRIVING ON THE ROAD. IT SEEMS THAT WHEN THIS VEHICLE WAS DESIGNED, TOO MUCH OF THE LIFTGATE'S STRUCTURE WAS LEFT TO RELY ON THE STABILITY OF PLASTIC AND GLASS. FOR INSTANCE, ON MY VEHICLE, AFTER BREAKAGE OF THE MOLDING, THE FORCE EXERTED BY THE GLASS LIFT ARMS CAUSED THE ADHESIVE TO SEPARATE FROM THE WINDOWS HINGE, LEAVING IT "DANGLING BY A THREAD". I FEEL THAT THIS A PROBLEM THAT HAS OCCURRED IN TOO MANY CASES; A PROBLEM THAT COULD POTENTIALLY CAUSE SAFETY ISSUES WHILE DRIVING ON THE ROAD. IT IS AN EXPENSIVE PART TO REPLACE ($700-$1000, WITH LABOR). CHEVROLET HAS SINCE REDESIGNED THE TRAILBLAZER VEHICLES TO TAKE CARE OF THIS PROBLEM. I FEEL THAT CHEVROLET SHOULD BE HELD RESPONSIBLE TO CORRECT THEIR DESIGN ERROR ON THE OLDER VEHICLES, INSTEAD OF LEAVING IT UP TO THE CONSUMER TO PAY FOR IT OUT OF THEIR OWN POCKET.*TR

THE REAR WINDOW IN THE GATE ON MY 2003 TRAILBLAZER HAS BECOME DISCONNECTED ON ONE SIDE AT THE HINGE. IT APPEARS TO BE A DEFECT WITH THE WAY IT IS ADHERED (VIA SOME SORT OF GLUE) AS THERE IS NO DAMAGE TO THE AREA ITSELF. AS MY VEHICLE IS AN EXT MODEL, IT HAS A SECTION ACROSS THE VERY TOP THAT IS ALSO SIMPLY GLUED TO THE BODY WHICH HOLDS THE CENTRALLY MOUNTED BRAKE LIGHT. I'VE NOTICED SINCE PURCHASING THE VEHICLE LAST YEAR THAT THIS SECTION WITH THE BRAKE LIGHT COMES IN CONTACT WITH THE ROOF WHEN YOU OPEN THE MAIN GATE & SEEMS REALLY LOOSE HOT WEATHER. TODAY, WHEN I OPENED THE REAR LATCH/GATE I HEARD AN UNUSUAL SOUND AND WHEN I CLOSED THE GATE & INSPECTED IT I NOTED THAT THE WINDOW PORTION APPEARED SKEWED. UPON FURTHER EXAMINATION OF THE WINDOW AREA I DISCOVERED THAT THE PASSENGER-SIDE WINDOW HINGE HAD SEPARATED FROM THE GATE & WAS NO LONGER FORMING A SEAL. AS THERE WAS NO PHYSICAL DAMAGE TO THE AREA (THE HINGE SIMPLY LIFTED RIGHT AWAY FROM THE AREA IT WAS GLUED TO), ONE WOULD ASSUME THAT THIS MUST A DEFECT IN ASSEMBLY & MAY AFFECT SIMILAR VEHICLES. IF THE OTHER HINGE WERE TO ALSO SEPARATE THE ENTIRE GLASS ASSEMBLY WOULD NO LONGER BE ATTACHED TO THE VEHICLE WHICH COULD RESULT IN CAUSING A COLLISION OR OTHER INCIDENT TO VEHICLES FOLLOWING THE AFFECTED VEHICLE. OBVIOUSLY, OTHER DAMAGE CAUSED BY RAIN/ELEMENTS WOULD ALSO BE A CONCERN WITH THE LACK OF PROPER SEAL BETWEEN THE WINDOW & THE REAR GATE. *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.
