MY 2004 CHEVROLET TRAILBLAZER 4WD HAS 41,000 MILES ON THE ODOMETER. RECENTLY THE SERVICE ENGINE SOON (SES) LIGHT BECAME ILLUMINATED. PERSONAL INSPECTION OF THE VEHICLE REVEALED A SMALL CRACK IN THE PLASTIC FUEL TANK. THE CRACK WAS LOCATED AT THE "WELD" OR JOINT WHERE THE PLASTIC FUEL FILL PIPE CONNECTS TO THE TANK. THIS FILL PIPE ALSO HOUSES THE FUEL TANK INLET CHECK VALVE (ICV). AS MY VEHICLE WAS PAST THE THREE-YEAR - 36,000 MILE WARRANTY PERIOD I ATTEMPTED TO GLUE THE LEAKING CRACK. THIS HELD FOR A FEW WEEKS, THE SES LIGHT WENT OUT AND THERE WAS NO ODOR OR APPEARANCE OF GASOLINE LEAKING FROM THE AREA. EVENTUALLY, THOUGH, THE LEAK RETURNED, EVIDENCED BY THE SES LIGHT ILLUMINATION AND GASOLINE LEAKING FROM THE REPAIRED AREA. ANOTHER REPAIR ATTEMPT WAS MADE AND IS CURRENTLY UNDER OBSERVATION. THIS EXACT PROBLEM APPEARS TO BE DETAILED IN GENERAL MOTORS DOCUMENT ID# 1985459; SUBJECT: SPECIAL COVERAGE ADJUSTMENT - FUEL TANK INLET CHECK VALVE FRACTURE #07099 - (06/07/2007). THIS REFERENCED DOCUMENT ONLY PERTAINS TO 2002-2004 CHEVROLET TRAILBLAZER EXT AND GMC ENVOY XL, BOTH LONGER WHEELBASE MODELS THAN MY STANDARD LS MODEL. UPON MY DISCOVERY OF THIS MANUFACTURER KNOWN PROBLEM WITH THIS VEHICLE MODEL, I TOOK MY TRAILBLAZER TO THE LOCAL CHEVROLET DEALER TODAY. THE SERVICE CONSULTANT SAID HE WAS NOT FAMILIAR WITH MY PROBLEM AND WAS UNABLE TO ACCESS THE COMPUTER DATABASE FOR ANY RELEVANT DOCUMENTS FOR MY VEHICLE. HE DID TAKE A COPY OF THE ABOVE REFERENCED SPECIAL COVERAGE ADJUSTMENT DOCUMENT AND PROMISED A RETURN CALL TOMORROW. *TR

IN ADDITION, THE ENGINE WARNING INDICATOR ILLUMINATED SPORADICALLY ON THE INSTRUMENT CONTROL PANEL. SHE TOOK HER VEHICLE TO THE DEALER AND THEY STATED THAT FUEL VAPORS WERE LEAKING AND COLLECTING ON TOP OF THE MODULE. THE FAILURE CAUSED FUEL TO SPILL ONTO THE GROUND. THE CONTACT WOULD HAVE TO PAY $1,300 TO HAVE THE VEHICLE REPAIRED BECAUSE IT WAS NOT REGISTERED IN A SALT BELT STATE. SECONDLY, SHE NOTICED THAT THE GAUGES ON THE INSTRUMENT PANEL WERE INOPERATIVE AND DISPLAYED INACCURATE INFORMATION. THE DEALER STATED THAT THE VIN WAS NOT INCLUDED IN THE MANUFACTURER'S RECALL FOR THE INSTRUMENT CONTROL PANEL; THEREFORE, SHE WOULD HAVE TO PAY $550 TO REPAIR THE COMPONENT. CURRENTLY, NO REPAIRS HAVE BEEN MADE. THE FAILURE MILEAGE WAS 66,000 AND CURRENT MILEAGE IS 73,000. UPDATED 3/11/09 *CN UPDATED 03/13/09. *JB

I HAVE A 2004 CHEVY TRAILBLAZER LT. ON THE GAS TANK WHERE THE FILL NECK IS CONNECTED TO IT, THE SEAM IS CRACKED AND LEAKS GAS. I HAVE TRIED TO HAVE THE TANK REPAIRED BUT WITH NO SUCCESS. I HAVE CONTACTED GM AND VISITED A CHEVY DEALERSHIP ABOUT THIS CONCERN AND THEY WANT ME TO PAY $1,300 + PLUS CHANGE THE TANK. THIS VEHICLE HAS NOT BEEN DAMAGED IN A WRECK. THIS IS SIMPLY A DEFECTIVE PART THAT CAUSES A HUGE SAFETY CONCERN FOR ME. I HAVE READ OF OTHER TRAILBLAZER GAS TANKS CRACKING AT THE SAME LOCATION THAT RESULTED IN A CAMPAIGN TO REPLACE THEM. I THINK THAT GM SHOULD REPLACE THESE TANKS THAT CRACK BEFORE THEY RESULT IN A FIRE AND CAUSE DAMAGE OR INJURY. GM AND THE DEALERSHIP HAVE DEMONSTRATED NO CONCERN FOR MY SAFETY AND THAT OF MY FAMILY. I FEEL THAT THIS SAFETY ISSUE SHOULD EB DEALT WITH BY THE MANUFACTURER. THANK YOU FOR YOUR TIME. *TR

4RQ17002 · 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.

Opened Jul 10, 2007 · Closed Aug 28, 2008
Status: closed (inferred from source dates) · Fuel System, Gasoline:delivery:fuel Pump
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
GM STATES THAT SOME BRAKE/TAIL LAMP BULBS CAN PREMATURELY BECOME INOPERATIVE DUE TO MALFUNCTIONING BRAKE/TAIL LAMP SOCKETS.ON MARCH 2, 2004, GM INITIATED A 6-YEAR/72,000 MILE SPECIAL POLICY FOR 989,487 SUBJECT VEHICLES TO INSPECT AND REPLACE THE REAR BRAKE/TAIL LAMP BULB SOCKET ASSEMBLIES.ON APRIL 4, 2004, THE OFFICE OF DEFECTS INVESTIGATION (ODI) OPENED A PRELIMINARY EVALUATION (PE04-032) BASED ON CONSUMER COMPLAINTS ALLEGING BRAKE LIGHTS NOT OPERATING WHEN THE BRAKE PEDAL IS DEPRESSED.ON AUGUST 3, 2004 ODI UPGRADED PE04-032 TO AN ENGINEERING ANALYSIS (EA04-021).BY LETTER DATED OCTOBER 27, 2004 GM NOTIFIED NHTSA THAT IT WILL CONDUCT A SAFETY RECALL (NHTSA # 04V527) COVERING SUBJECT VEHICLES THAT WERE NOT ALREADY REPAIRED UNDER GM'S SPECIAL POLICY.MY 2004 SUBJECT VEHICLES BUILT AFTER AUGUST 8, 2003 CONTAIN IMPROVED BRAKE LAMP ASSEMBLIES AND ARE NOT INCLUDED IN THE RECALL.GM DEALERS WILL INSTALL THE IMPROVED BRAKE LAMP ASSEMBLY ON SUBJECT VEHICLES BUILT ON AUGUST 8, 2003 AND EARLIER.THE ACTION TAKEN BY GM IS SUFFICIENT TO RESOLVE THE ISSUES RAISED BY THIS INVESTIGATION.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.
PE04032 · Brake Lamp Failure
Opened Apr 6, 2004 · Closed Aug 3, 2004
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.
