THE FRONT AIR VENTS IN MY 2004 TRAILBLAZER QUIT WORKING AFTER I INSTALLED A NEW BATTERY. MY FRONT AIR VENTS WILL NO LONGER WORK. AFTER RESEARCHING THIS ON THE INTERNET IT APPEARS THAT THIS IS A COMMON PROBLEM WITH THE CHEVY TRAILBLAZER. IT WILL REQUIRE THE PURCHASE AND INSTALLATION OF A NEW CONTROL MODULE TO REGULATE THE AIR FLOW SO THE VENTS WILL WORK. THIS IS A COMPONENT/DESIGN PROBLEM THAT GM NEEDS TO FIX NOT THE CONSUMER. *TR

I HAVE OWNED THIS VEHICLE FOR 2 1/2 YEARS. THE FIRST PROBLEM WAS NOTICEABLE ONLY AT NIGHT WHEN THE WINDSHIELD GLARE WAS SO BAD ON THE FREEWAY THAT I COULD NOT SEE VERY WELL. WE HAD THE WINDSHIELD REPLACED. THE SECOND PROBLEM HAS BEEN ON-GOING FOR THE PAST SIX TO EIGHT MONTHS. THE SPEEDOMETER SOMETIMES WORKS, BUT IS USUALLY NOT VERY CORRECT, AND MOST OF THE TIME IT JUST PICKS A NUMBER AND SITS THERE FOR SEVERAL DAYS, WHETHER THE CAR IS RUNNING OR NOT. I USUALLY USE THE RPMS TO FIGURE OUT HOW FAST I AM GOING UNTIL MY MECHANIC CAN FIX IT FOR MORE THAN A WEEK AT A TIME. *TR

THE CAR DRIVES FINE BUT A FEW WEEKS AFTER PURCHASE, THE PASSENGER MIRROR STARTED MOVING. I HAVE A CAR WHERE WHEN YOU OPEN THE CAR WITH YOUR DESIGNATED KEY, THE MIRRORS SET TO YOUR PREFERENCES. I KEPT RESETTING THE MIRROR AND A FEW DAYS LATER THEY WOULD NOT HOLD THE SET AGAIN. NOW EVERY TIME I SHUT OFF THE CAR AND GET BACK IN THE MIRRORS HAVE TO BE RESET. THERE HAVE BEEN TIMES WHEN I FORGET TO RESET THE MIRROR AND START DRIVING. I AM SO AFRAID I AM GOING TO HIT SOMEONE WHILE ATTEMPTING TO CHANGE LANES. I HAVE TO TRY TO RESET THE MIRROR WHILE DRIVING AND THIS TAKES MY ATTENTION AWAY FROM THE ROAD. I HAVE HAD THE CAR IN THE SHOP THREE TIMES IN KENTUCKY. AT FIRST THEY KEPT TELLING ME THEY COULDN'T FIND THE PROBLEM BECAUSE IT DIDN'T ACT UP FOR THEM BECAUSE IT WOULD HOLD FOR THE TIME THEY HAD THE CAR. FINALLY THEY DID ANOTHER TEST AND IT SHOWED I HAD A FAULTY PART IN THE DOOR THAT IS ATTACHED TO THE MIRROR. THEY REPLACED THAT AND IT HELD FOR ABOUT A WEEK AND A HALF AND THEN STARTED AGAIN. I WAS IN THE PROCESS OF MOVING TO SOUTH CAROLINA SO I TOOK IT TO A DEALERSHIP THERE. THEY COULDN'T FIND ANYTHING WRONG AND CHARGED ME FOR THE VISIT EVEN THOUGH THIS HAS BEEN AN ONGOING PROBLEM. I CALLED GM AND TALKED BY E-MAIL TO THEIR CUSTOMER SERVICE AND HAVE RECEIVED NO HELP AT ALL. THEY SAID THEY WOULD CALL BACK (THEY CALLED ONCE) BUT I HAVEN'T HEARD FROM THEM. *JB

WINDSHIELD WIPER MOTOR WILL NOT SHUT OFF IN 2004 CHEVROLET TRAILBLAZER EXT. 2003 MODEL YEAR HAD SAME PROBLEM AND WAS RECALLED BY MANUFACTURER. *JB
ON CERTAIN TRUCKS AND SPORT UTILITY VEHICLES, THE DRIVER WISHING TO SIGNAL A TURN BY MOVING THE DIRECTIONAL SIGNAL LEVER, (UP OR DOWN) MAY CAUSE THE FRONT MARKER/TURN LIGHTS AND REAR TURN LIGHTS TO FLASH IN A MANNER SIMILAR TO HAZARD WARNING, RATHER THAN FLASHING ON THE DESIRED SIDE ONLY.
Consequence & remedy
Consequence: THE DRIVER MAY NOT BE ABLE TO CLEARLY SIGNAL THEIR INTENTIONS TO TURN, CHANGE TRAVEL LANES, OR POTENTIALLY WARN OTHERS OF AN IMPAIRED VEHICLE OPERATING CONDITION INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE SUSPECT FLASHER MODULES WITH A NEW FLASHER MODULE DESIGNED WITH SEALED RELAYS AND MORE DURABLE CONTACT MATERIAL INSIDE OF THE RELAYS FREE OF CHARGE. THE RECALL BEGAN ON AUGUST 4, 2005. ISUZU BEGAN MAILING OWNER LETTERS ON AUGUST 4, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, ISUZU AT 1-800-255-6727, BUICK AT 1-866-608-8080, AND OLDSMOBILE AT 1-800-630-6537.
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.

RQ17002 · 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.

Status: closed (inferred from source dates) · Exterior Lighting:brake Lights
THE OFFICE OF DEFECTS INVESTIGATION (ODI) OPENED THIS INVESTIGATION ON MODEL YEAR (MY) 2002-04 CHEVROLET TRAILBLAZER VEHICLES.GM REPORTS THAT OTHER VEHICLES SHARING THIS PLATFORM AND BRAKE LAMP DESIGN ARE THE MY 2002-2004 CHEVROLET TRAILBLAZER EXT; GMC ENVOY, XL, XUV; OLDSMOBILE BRAVADA AND 2004 BUICK RAINIER.COMPLAINTS ALLEGE THAT THE REAR BRAKE LAMP DOES NOT OPERATE WHEN THE BRAKE PEDAL IS DEPRESSED.THERE IS NO INDICATION TO THE DRIVER FROM INSIDE THE VEHICLE THAT ONE OR MORE BRAKE LAMPS BULBS ARE NOT FUNCTIONING.GM FOUND THAT HEAT FROM THE BULB COULD DEFORM THE LAMP SOCKET, PRODUCE ELECTRICAL ARCING AND AN INOPERATIVE BULB.TO CORRECT THE CONDITION, GM CHANGED THE BULB TO A BULB THAT TRANSMITS LESS HEAT TO THE SOCKET AND CHANGED THE SOCKET TO A THERMOPLASTIC POLYMER TO IMPROVE THERMAL STABILITY.THESE CHANGES WERE IMPLEMENTED INTO PRODUCTION VEHICLES ON OCTOBER 1, 2003.GM IMPLEMENTED A SPECIAL POLICY BY NOTIFYING CONSUMERS THAT IF THEY SHOULD EXPERIENCE A BRAKE LAMP FAILURE TO GO TO THEIR GM DEALERSHIP TO HAVE THE CIRCUIT BOARD CONTAINING THE BRAKE LAMP REPLACED ALONG WITH NEW BULBS.THIS POLICY IS GOOD FOR THE FIRST 6 YEARS OR 72,000 MILES OF THE LIFE OF THE VEHICLE.ODI WILL UPGRADE THIS INVESTIGATION TO EA 04-021 AND INCLUDE THE ABOVE MENTIONED VEHICLES.
