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

IN SEPTEMBER 2009, MY 2004 TRAILBLAZER STARTED GOING HAYWIRE! IT LOST ALL POWER (WHILE GOING DOWN THE INTERSTATE), THE POWER/CIGARETTE OUTLETS STOPPED WORKING, THE DOORS STARTED LOCKING THEMSELVES (SOMETIMES WITH THE KEYS IN THE IGNITION) , THE RADIO WOULD GO LOUD OR STOP WORKING, MY SPEEDOMETER WENT NUTS (LIKE SAYING THAT I WAS DOING 65MPH, WHEN I WAS AT A COMPLETE STOP OR 120MPH DOWN THE HWY), THE SERVICE ENGINE SOON LIGHT WOULD GO ON AND OFF,AND MY HEATER WILL NOT BLOW OUT THE VENTS IN THE DASH. WE HAVE TAKEN IT TO A MECHANIC. HE TRIED EVERYTHING FROM REPLACING THE BATTERY, FUEL FILTER, AND SPARK PLUGS. HE EVEN HOOKED IT UP TO HIS SCANNER (WHICH SHOWED THAT THERE WAS NOTHING WRONG WITH THE CAR) ALL THIS AND $700.00 LATER I STILL HAVE THE SAME PROBLEMS. NOW I'M TOLD THAT THE ELECTRICAL PANEL WILL NEED TO BE REPLACED AT A COST AROUND $500-$900!! IF YOU LOOK AT CARCOMPLAINTS.COM YOU SEE THAT THERE ARE MANY MORE PEOPLE LIKE ME WITH THE SAME CAR AND THE SAME PROBLEMS. THIS IS A HUGE SAFETY ISSUE.HOW LONG WILL IT BE BEFORE SOMEONE PUSHES CHEVY INTO DOING A RECALL? DOES SOMEONE HAVE TO BE KILLED OR KILL SOMEONE ELSE FOR THIS TO HAPPEN? I WAS SO GLAD TO GOOGLE CAR COMPLAINTS AND FIND THAT IT WASN'T JUST ME THAT WAS HAVING SO MANY PROBLEMS WITH THIS TRAILBLAZER. *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.

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.
EA04021 · Brake Lamp Failure
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.
