I PURCHASED MY 2004 TRAILBLAZER OF THE ORIGINAL OWNER WITH 35000 MILES ON THE SPEEDOMETER. AT 75000 MILES THE DOOR LOCKS STARTED CLICKING AS IF LOCKING AND UNLOCKING. I TOOK IT TO A CHEVY DEALER AND THE MECHANIC SAID IT WAS DEFINITELY STRANGE AND I WOULD NEED TO MAKE AN APPOINTMENT TO HAVE THEM LOOK AT IT. JUST HIM SAYING DEFINITELY STRANGE TO MY EARS SAID EXPENSIVE. MY SISTER HAD THE SAME VEHICLE DIFFERENT COLOR AND HERS HAD THE SAME PROBLEM. NOW HOW STRANGE IS THAT? I BROKE THE APPOINTMENT AND GOT USED TO THE CLICKING. SOMETIMES IT WOULD STOP FOR A WEEK OR SO AND CLICK SOME MORE. THE CLICKING WAS LOUD AS IF YOU COULD IMAGINE THE SOUND WHEN YOU LOCK ALL THE DOORS WITH ONE CLICK. CLICK CLICK CLICK CLICK EVERY HALF MINUTE OR SO. THEN THE TACHOMETER WENT NUTS. SOMETIMES IT WORKED SOMETIMES IT DIDN'T. SAME WITH THE GAS GAGE, OIL PRESSURE, TEMP GAGE AND BATTERY. ONCE THE WIPERS WOULDN'T COME ON WHILE BEING CAUGHT IN A RAIN STORM. THE STARTED WORKING AGAIN ABOUT 15 MILES LATER. NOW THE ELECTRIC DOOR LOCKS ARE ACTING UP SETTING OFF THE ALARM. I NO LONGER LOCK THE DOORS DUE TO THE ALARM GOING OFF FOR NO REASON. DEACTIVATING THE ALARM CAN BE A CHORE AS PUSHING THE CORRECT BUTTON TO SHUT IT UP ONLY WORKS AFTER PUSHING IT A FEW TIMES. WE HAVE CHECKED FOR PINCHED WIRES AND CHECKED THE FUSES TO NO AVAIL. WITHOUT THESE ELECTRICAL PROBLEMS I WOULD BE ONE HAPPY CUSTOMER! *TR

I BOUGHT THIS CAR ABOUT 4 YEARS AGO AND IT HAS BEEN NOTHING BUT AN ELECITRICAL MESS. FIRST MY HEAD LIGHTS WOULD GO OUT ONCE A MONTH, THEN A COUPLE TIMES A MONTH, THEN ONCE A WEEK. MY BRAKE LIGHTS STARTED DOING THE SAME. OUR FAMLIY MECHHANIC COULDN'T FIGURE IT OUT, HE JUST KEPT REPLACING THEM AND SENDING THE BAD BULBS IN FOR WARRANTY. A COUPLE TIMES THE PIGTAILS AND LAMPS HAD TO BE REPLACES. ALSO 3 SEPERATE OCCASIONS BOTH HEADLIGHTS WENT OUT AT ONCE WHILE DRIVING. AND I HAD TO DRIVE HOME IN THE DARK WITH NO HEAD LIGHTS ON. I TOOK IT THE CHEVY DEALERSHIP AFTER THE THIRD TIME ABD APPARENTLY MY FUSE BOX WAS MELTED AND NEEDED TO BE REPLACED. SPENT OVER 1000.00 DOING THAT AND IT WORKED OKAY FOR ABOUT A YEAR. THEN HEADLIGHTS STARTED GOING OUT AGAIN AND BRAKE TLIGHTS AS WELL. NOT ONCE A WEEK, BUT STILL ABOUT ONCE A MONTH OR EVERY OTHER MONTH. RECENTLY MY DRIVERS WINDOW STOPPED WORKING AND I COULDN'T CONTROL THE MASTER SWITCH TO LOCK MY CAR OR ROLL UP MY WINDOWS. THE CLUSTER PANEL IN THE DOOR NEEDED TO BE REPLACED. ALSO, HAD TWO SENSORS THAT NEEDED TO BE REPLACED BECAUSE MY 4 WHEEL DRIVE, PARKING BRAKE, AND CRUSIE CONTROL WOULD STOP WORKING ALL AT ONCE AND THE LIGHTS WOULD BE LIT UP ON THE DASHBOARD. I WASNT' ABLE TO USE ANY OF THEM UNTIL THE SENSOR WAS REPLACED. ALSO THE POWER SHORTED OUT IN MY SIDE MIRROS, SO I CAN'T ADJUST THE MIRRORS WITH THE CONTROL OR THEY START TILITING BACK AND FORTH LIKE CRAZY ON THEIR OWN. I HAVE TO GET OUT OF THE CAR AND ADJUST THEM MANUALLY. GM NEEDS TO DO A RECALL, THIS CAR IS NOT SAFE AND I WILL NOT BE BUYING A GM CAR WHILE I LOOK FOR A NEW CAR SOON. *JS

THIS WAS ACTUALLY THE SECOND OR THIRD INCIDENT WHERE THE KEY GOT STUCK IN THE IGNITION, BLAZER WAS IN PARK THE LIGHTS REMAINED ON SO DID THE RADIO ANYTHING THAT IS TYPICALLY ON DURING AUX, BUT THIS WAS THE BEGINNING OF A LONG PROBLEM THAT LEAD TO ME TRADING OFF..THE KEY GETS STUCK YOU CAN NOT REMOVE IT CAUSED THE BATTERY TO GO BAD, IT WOULD BEGIN TO HAPPEN OFTEN THE SERVICE ENGINE SOON LIGHT WOULD COME ON, THE TRANSMISSION WOULD NOT SHIFT ABOVE 3RD GEAR, ALSO SHORTLY AFTER THE PURCHASE IN SEPT OF 2011 THE SPEEDOMETER STOPPED WORKING. THE BLAZER DIED 3 TIMES GAUGES ON DASH WOULD PERIODICLY STOP WORKING. MY SERVICE 4 WHEEL WOULD COME ON RANDOMLY THE KEY ISSUE WAS THE BIGGEST PROBLEM BUT IT WAS ONLY A MATTER OF TIME BEFORE OTHER THINGS WENT WRONG. WHEN THE KEY WOULD GET STUCK IN THE IGINTION AS STATED THE TRANSMISSION WOULD NOT SHIFT PROPERLY IN THE BEGINNING THE TRANSMISSION WOULD ACT OUT ONCE YOU TOOK IT OUT OF PARK IT WAS NOTICEABLE BUT AS THE PROBLEM BECAME WORSE IT STARTED HAPPENING DRIVING DOWN THE HIGHWAY I NOTICED ONCE THAT I HAVE SUCCESSFULLY MADE IT THROUGH 1-2-3 BUT NEVER GOT OUT OF 3. I SHOULD STATE THAT WHEN THE KEY WAS STUCK I WOULD HAVE TO MANUALLY SHIFT THROUGH THE FIRST AND SECOND THEN PUT IT INTO DRIVE OTHERWISE THE CAR HAD NO POWER BECAUSE IT WOULD BE STUCK IN THE HIGHER GEAR.TRIED TO CONTACT THE DEALERSHIP AS THERE WAS A RECALL ON THE DASH FOR THE 2003 MODEL AND THEY TOLD US IT WASNT A SAFETY PROBLEM I DO NOT UNDERSTAND HOW RANDOM LOSS OF POWER AND RANDOM CAR DYING IS NOT A SAFETY ISSUE, I HAVE BEEN WATCHING THE LIST OF GM RECALLS AND I HAVE NOT SEEN MUCH ABOUT THE TRAILBLAZERS, AND IT BOTHERS ME THAT I AM SURE THERE ARE OTHER ISSUES LIKE THE ONES THAT I HAD. ON ANOTHER NOTE TRANSMISSION RELATED MY NEIGHBORS JUST HAD TO GET RID OF THEIR TRAILBLAZER 2006 FOR TRANSMISSION PROBLEMS. *JS

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.
