THE CHECK ENGINE LIGHT KEPT COMING ON AND THEY REPLACED A SENSOR AND HAD ME BUY A NEW FUEL CAP WHICH DIDN'T FIX THE PROBLEM. I HAD TAKEN MY VEHICLE TO THE DEALERSHIP 5 TIMES BEFORE THEY CORRECTLY DIAGNOSED THE PROBLEM AS A FUEL TANK VAPOR LEAK. THE ONLY WAY TO FIX THIS IS TO REPLACE THE ENTIRE FUEL TANK. MY VEHICLE HAS BEEN IN THE THE SERVICE DEPARTMENT FOR THE PAST 3 WEEKS AND THE FUEL TANK IS ON NATIONAL BACKORDER. I HAVE BEEN READING ABOUT THIS BEING A PROBLEM ON THE TRAILBLAZER EXT. ON MANY WEBSITES AND BLOGS. IT SEEMS THAT THIS WOULD BE OF A HUGE SAFETY CONCERN. *TR

I WAS JUST READING THE COMPLAINTS & THOUGHT I WOULD SUBMIT A FEW OF MY OWN. GAS FILLLING IS ALWAYS A TASK AS TANK ALWAYS SEEMS TO "OVERFLOW" & GAS SPRAYS OUT EVERYWHERE. I WAS TOLD IT IS BECAUSE OF THE TYPE OF FILLER LINE THAT GM USES. HEADLIGHTS CONSTANTLY GOING FROM NORMAL TO DIM, TO DIMMER, THEN BACK TO NORMAL, REGARDLESS OF DRIVING CONDITIONS. SAW THE ONE FROM THE PERSON BEING SHOCKED, THIS TOO HAS ALWAYS HAPPENED TO ME SINCE THE FIRST DAY I BOUGHT THE TRAILBLAZER. IF I TOUCH THE METAL OF THE DOOR UPON EXITING THE VEHICLE THERES A LARGE JOLT FROM STATIC ELECTRICITY I ASSUME. THE ARC FROM THIS JOLT IS VERY VISIBLE & I ESTIMATE IT TO 2 INCHES IN LENGTH AT TIMES (LONGER YOUR IN THE VEHILCE...BIGGER THE ARC). ALL THE RUBBER TRIM ON THE BACKHATH HAS COME OFF. PLASTIC LINING USED ON FENDERWELLS CONSTANTLY COMING LOOSE & MUST BE REATACHED. CARPET AROUND PEDALS HAS ALL COME LOOSE. I BOUGHT THIS VEHICLE NOV. 1 2004 & IT IS HARDLY BEEN DRIVEN WITH ONLY 6,000 MILES YET SEEMS TO BE FALLING APART ALREADY. *JB

I BOUGHT THIS VEHICLE BRAND NEW AND SINCE PURCHASE IT IS IN AND OUT OF THE SHOW WITH NUMEROUS ELECTRICAL AND GAS PROBLEMS. EVERYTIME YOU PUT GAS IN THE VEHICLE IT SPILLS OUT FROM THE UNDERSIDE. THE DEALERSHIP HAS REPLACE PARTS PERTAINING TO THE FUEL SYSTEM AND IT HAS NOT SOLVED THE PROBLEM. MY RADIO HAS BEEN REPLACED AND STILL DOES NOT WORK PROPERLY. MY HEADLIGHTS DIM UP AND DOWN, THE AIR BLOWS LOW AND HIGH THE INTERIOR LIGHTS FLASH OFF AND ON THE ENGINE RUNS ROUGH AND ALL THESE SYMPTOMS HAPPEN SPORADICALLY. IT HAS BEEN IN THE DEALERSHIP NUMEROUS TIMES AND EVERYTIME I TAKE IT THEY STATE THEY CANNOT DUPLICATE THE PROBLEM. THIS VEHICLE I FEEL IS A SAFETY ISSUE AND I DO NOT FEEL COMFORTABLE PUTTING MY FAMILY IN IT. I AM CURRENTLY FILING A LEMON LAW COMPLAINT WITH THE BETTER BUSINESS BUREAU. *JB

IT HAPPENED SEVERAL TIMES BEFORE I TOOK MY CAR IN TO THE DEALER. I THOUGHT MAYBE IT WAS THE GAS STATION I WAS USING. SO I TRIED SEVERAL DIFFERENT PUMPS IN DIFFERENT CITIES AND THE SAME THING HAPPENED. THAT'S WHEN I DECIDED TO TAKE THE CAR IN FOR SERVICE.*AK

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.

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.

Opened Aug 3, 2004 · Closed Nov 4, 2004
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.
