TL*THE CONTACT OWNS A 2003 CHEVROLET TRAILBLAZER EXT. WHEN THE CONTACT PULLED AWAY FROM A STOP SIGN AND MADE A RIGHT TURN, THE DRIVER'S SIDE DOOR OPENED ON ITS OWN. AS A RESULT, ANOTHER VEHICLE ALMOST STRUCK THE DOOR. THE CONTACT COULD NOT CLOSE THE DOOR RIGHT AWAY BECAUSE HE ONLY HAS ONE ARM; THEREFORE, THE DOOR REMAINED OPEN FOR APPROXIMATELY 500 FEET. THE CONTACT HAD TO SECURE THE DOOR WITH A BUNGEE CORD. HE TOOK THE VEHICLE TO THE DEALER FOR A DIAGNOSTIC AND WAS CHARGED $105. HE WAS THEN INFORMED THAT THE REPAIR WOULD COST $600. BECAUSE HE IS ON DISABILITY, HE CANNOT AFFORD TO PAY FOR THE REPAIRS. THE FAILURE AFFECTS 3 OUT OF THE 4 DOORS ON THE VEHICLE WHEN MAKING RIGHT TURNS. THE FRONT AND REAR DRIVER SIDE DOORS OPEN AND, WHEN MAKING LEFT TURNS, THE REAR PASSENGER DOOR OPENS AS WELL. THE CURRENT MILEAGE WAS 83,000 AND FAILURE MILEAGE WAS 80,000.

DRIVERS SIDE FRONT WINDOW FALLS DOWN WITHOUT WARNING, INTO THE DOOR. WILL NOT ROLL UP INTO THE FULLY CLOSED POSITION WHEN ELECTRIC WINDOW SWITCH IS ACTIVATED. MUST MANUALLY PUSH THE GLASS INTO THE FULLY CLOSED POSITION, HOWEVER, AS STATED ABOVE, IT WILL FALL WITHOUT WARNING. THIS CREATES A SERIOUS HAZARD IN THAT WHEN THE WINDOW FALLS WITHOUT WARNING, NOT ONLY CAN THE DRIVER BE STARTLED AND MAKE A DRIVING ERROR, BUT ALSO, GIVEN THE EXTERIOR CONDITIONS, CREATE A VERY UNSAFE DRIVING / OPERATIONAL ENVIRONMENT WHICH COULD RESULT IN A CRASH. *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

305V494000 · Latches/locks/linkages:doors:latch
Oct 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.
04V527000 · Exterior Lighting:brake Lights
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.
04V046000 · Visibility:windshield Wiper/washer
Feb 4, 2004
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.
