BOUGHT VEHICLE USED IN 2005, HAD 56,000 MILES ON IT AT THE TIME. AT 76,000 MILES THE SPEEDOMETER WENT OUT COMPLETELY HAD TO BE REPLACED. REPLACED THE SPEEDOMETER $500.00 COST. IN 2007, THE DASHBOARD AND ALL THE GAUGES STARTED GOING CRAZY, HAD IT CHECKED AT A CHEVY DEALER THEY CONFIRMED IT WAS AN ELECTRICAL PROBLEM THAT WAS NOT COVERED UNDER MY WARRANTY AND WAS GONNA COST WAY TO MUCH TO FIX. LATER IN 2009 THE ALARM SYSTEM DECIDED IT WOULDN'T WORK ANYMORE, OR IT WOULD SET ITSELF. (GOT LOCKED IN THE CAR FOR AT LEAST 20 MINUTES OR MORE, WOULDN'T START EITHER TO RESET THE PROCESS), THE REMOTE KEY WOULDN'T WORK AS WELL. HAD IT INSPECTED AGAIN, FULL DIAGNOSTIC DONE BY THE CHEVY DEALER & ALSO BY FIRESTONE, EVERY ISSUE THAT THE CAR HAS IS RELATED TO THE ELECTRICAL SYSTEM FAILING CONSTANTLY. HEADLIGHTS GO OFF AND ON WHEN THEY FEEL LIKE IT, HIT THEM THEY COME BACK ON SOMETIMES, TAIL LIGHTS HAVE GONE OUT, NO NEED TO REPLACE BULBS THAT IS NOT THE ISSUE. FULL DIAGNOSTIC COST MONEY, I HAVE CALLED THE BETTER BUSINESS BUREAU TO SEE WHAT I COULD DO TO MAKE CHEVY PAY FOR THIS DISFUNCTIONING VEHICLE BUT, OF COURSE IT IS A BUNCH OF RED TAPE AND POLITICAL BULL CRAP. I DO NOT RECOMMEND THIS VEHICLE TO ANYONE TOO MUCH MONEY WILL BE LOST AND STILL NO RESULTS. CURRENTLY MY VEHICLE HAS OVER 100,000 MILES ON IT AND THE GAUGES STILL GO OUT EVERY NOW AND THEN, THE HEADLIGHTS STILL GO OUT AND THE ALARM STILL SETS ITSELF WHEN IT FEELS LIKE IT. I PRAY OVER THIS VEHICLE EVERYTIME I GET IN IT. *TR

I HAVE A 2004 CHEVY TRAILBLAZER; WHILE DRIVING ON THE HIGHWAY; ALL GAUGES, LIGHTS, ETC. ABRUPTLY STOPPED WORKING AND CONTINUE TO NOT WORK. I RESEARCHED ON LINE AND FOUND IT COULD BE WHAT IS CALLED THE "CLUSTER BOARD". I TOOK MY VEHICLE TO A LOCAL CHEVY DEALER IN DAYTONA BEACH FL. THEY INSISTED IT WAS THE IGNITION SWITCH. THEY REPLACED THAT MECHANISM FOR JUST UNDER $300. THE FOLLOWING WEEK (THIS OCCURRED IN 2010); THE EXACT SAME SITUATION RECURRED; SO I BROUGHT IT BACK TO THE DEALER AND THEY THEN AGREED IT WAS THE CLUSTER BOARD WHICH WOULD NOW COST ME CLOSE TO $700.00. IN ORDER TO AVOID BEING RIPPED OFF TO THE TUNE OF ALMOST $1K; I PURCHASED A GPS UNIT SO I COULD AT LEAST MONITOR MY SPEED. THE SPEED/RPMS NEVER REGISTER CORRECTLY; HOWEVER, SO FAR THE OTHER GAUGES SEEMS TO BE OK (EXCEPT FOR THE OIL PRESSURE, IT GOES OUT OF WHACK FREQUENTLY SO I JUST BRING IT IN QUICKLY TO MAKE SURE I HAVE SUFFICIENT OIL AND THAT IT'S CLEAR/CLEAN). MOST RECENTLY MY HEADLIGHTS JUST GO OUT WITHOUT WARNING; I AM ABLE TO USE THE HIGH BEAMS, BUT OF COURSE THAT PUTS ME IN JEOPARDY OF GETTING A TICKET. THERE ARE SO MANY COMPLAINTS ON THE 2004 CHEVY TRAILBLAZER - I DO NOT UNDERSTAND WHY THERE HAS NOT BEEN A RECALL ON THE CLUSTER BOARD AND THE ELECTRICAL ISSUES (LIGHTING). I CANNOT AFFORD TO HAVE ALL THE REPAIRS COMPLETED AND WOULD LIKE TO SEE CHEVROLET TAKE ON SOME RESPONSIBILITY FOR THE COST OF THESE FLAWS IN THE MANUFACTURING OF THIS VEHICLE. *KB

THE SPEEDOMETER STOPPED WORKING TODAY. I CHECKED ONLINE TO SEE IF ANYONE ELSE WAS HAVING THE SAME PROBLEM. APPARENTLY THERE IS A LOT OF US ALL EXPERIENCING THE SAME PROBLEM. I DON'T THINK IT IS FAIR THAT WE ALL HAVE TO PAY $500 TO REPAIR THE PROBLEM. IF WE ARE ALL HAVING THE SAME PROBLEM THERE IS OBVIOUSLY SOMETHING WRONG. *TR

DASHBOARD GAUGES ON OUR 2004 TRAILBLAZER HAVE BEEN FAILING ONE BY ONE. NO GAUGES EXCEPT THE SPEEDOMETER HAVE BEEN OPERABLE FOR MANY MONTHS. NOW, ON FRIDAY 11/11/11, THE SPEEDOMETER STOPPED WORKING! THIS IS A SERIOUS PROBLEM. I BELIEVE IT MUST BE CAUSED BY THE SAME ISSUES AS THE IDENTICAL WELL-PUBLICIZED PROBLEMS ON OTHER TRAILBLAZERS. IN ADDITION, SOME OF THE DASHBOARD LIGHTS (SEATBELT LIGHT, ETC.) REMAIN ON ALMOST ALL THE TIME. CHEVROLET SHOULD BE RESPONSIBLE FOR IMMEDIATE REPAIRS AT NO COST TO US, THE OWNER. THANK YOU. *TR

WE HAVE A LOW MILEAGE 2004 CHEVY TRAIL BLAZER (UNDER 45,000 MILES AS OF SEPTEMBER 2011). IN MARCH 2011, THE CHECK ENGINE LIGHT ILLUMINATED. WE HAD THE OIL CHANGED AND TRIED SOME FIXES WITH THE BATTERY CABLES. ALL RESET THE ENGINE LIGHT, BUT EACH TIME THE LIGHT WOULD AGAIN ILLUMINATE AFTER SEVERAL DAYS HAD PASSED. IN AUGUST 2011, WE TOOK IT TO TEXAS AUTO SERVICE TO HAVE THEM TEST THE ENGINE LIGHT SENSOR AND WE THEN PAID FOR THEM TO REPLACE THE CANISTER VENT SOLENOID. ONCE AGAIN, THE LIGHT TURNED OFF FOR A PERIOD OF DAYS AND THEN CAME BACK ON. IN LATE SEPTEMBER WE TOOK IT TO FIRESTONE - AND AFTER 2 DAYS OF TESTING, IT WAS DETERMINED THAT THE FUEL TANK HAD A CRACK. WE THEN PICKED IT UP FROM FIRESTONE AND TOOK IT TO BANKSTON CHEVROLET IN FT WORTH - AFTER ANOTHER DAY OF TESTING, THEY CONCURRED AND WE WERE FORCED TO PAY $1336.18 TO HAVE THE FUEL TANK REPLACED... OTHERWISE WE RAN THE RISK OF A FIRE. WE DID RESEARCH AND FIND THAT MANY OF THE GM TRUCKS HAVE HAD RECALLS ON THIS SPECIFIC FAILURE - BUT NOT OUR SPECIFIC YEAR/MODEL AND VIN NUMBER. *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.

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.

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.
