MY SPEEDOMETER AND RPM DIAL HAVE STOPPED WORKING ON MY 2004 CHEVY TRAILBLAZER. I CALLED THE 800 NUMBER AND THE LADY TOLD ME THAT I AM NOT COVERED FOR THEIR SPECIAL PROVISIONING FOR THIS KNOWN PROBLEM. THAT THEIR SPECIAL PROVISIONING ONLY COVERS VEHICLES 7YRS/70K MILEAGE. I HAVE OVER 90K MILES AND THEY ARE NOT WILLING TO COVER ME. I CAN?T AFFORD TO PAY FOR THIS TO BE FIXED. I WILL NEVER BUY ANOTHER CHEVY CAR I CAN?T BELIEVE THERE IS NO RECALL FOR THIS ISSUE. THERE ARE 1000'S OF COMPLAINTS ONLINE THIS SHOULD BE A RECALL. *TR

TWO YEARS AGO MY WIFE AND I WERE DRIVING OUR 2004 CHEVY TRAILBLAZER ON THE INTERSTATE WHEN OUR SPEEDOMETER, OIL GAUGE, TACHOMETER,AND VOLTMETER WENT OUT. WE COULD NOT SEEM TO FIGURE OUT WHY EVERYONE WAS PASSING BY US SO QUICKLY WHEN WE WERE GOING THE SPEED LIMIT ACCORDING TO THE SPEEDOMETER. THANKFULLY WE HAD GPS AND WERE ABLE TO FIGURE OUT QUICKLY WHAT WAS HAPPENING. THIS IS A VERY DANGEROUS PROBLEM. IF WE DIDN'T HAVE GPS WE WOULD HAVE ABSOLUTELY NO WAY OF KNOWING HOW FAST WE WERE GOING. SOON AFTER THIS HAPPENED, THE CHECK ENGINE LIGHT CAME ON AND WE WERE HAVING ALL KINDS OF ELECTRICAL PROBLEMS WITH SENSORS GOING BAD. I HAVE RESEARCHED THESE PROBLEMS AND IT SEEMS AS THOUGH WE ARE NOT THE ONLY ONES WITH THIS PROBLEM. GM HAS NOT ISSUED A RECALL ON THIS MODEL FOR THIS PROBLEM, YET THEY DID FOR THE SUBURBAN LINE FOR THE SAME PROBLEM. PLEASE, IF YOU CAN, DO SOMETHING ABOUT THIS PROBLEM. WE HAVE YET TO FIX THESE PROBLEMS HOPING FOR A RECALL BUT HAVE HAD NO LUCK. WE ARE NOW IN THE PROCESS OF FIXING THESE PROBLEMS SO WE CAN PASS INSPECTION. THANKYOU VERY MUCH. *TR

I HAVE HEARD FROM OTHERS WITH THE SAME ISSUE THAT EVENTUALLY THE SPEEDOMETER WILL QUIT AS WILL THE GAS GAUGE, OIL GAUGE, ETC. THIS IS A POTENTIAL HAZARD THAT HAS NOT BEEN RECALLED BY CHEVY. OTHER MODELS OF THE SAME YEAR HAVE BEEN RECALLED, BUT NOT THE TRAILBLAZER. *TR

I'VE HAD ISSUES WITH THE ODOMETER, GAS AND BATTERY GAUGES FOR ABOUT A YEAR. HOWEVER, NOW THE ODOMETER DROPS AND THE CAR STALLS AND SHUTS OFF WHEN I GO TO SLOW DOWN. THE CHECK GAUGES LIGHT CAME ON AND OFF FOR A SECOND. NO OTHER LIGHTS ARE ON SO I HAVE NO IDEA WHAT THIS IS. CAR HAS ABOUT 75,000 MILES. *TR

I HAVE A 2004 CHEVY TRAILBLAZER. MY SISTER IN LAW HAS A 2005 CHEVY TRAILBLAZER. MY RPM DIAL ENT CRAZY A YEAR AGO AND NOW MY SPEEDOMETER IS OUT. I HAVE 82000 MILES ON IT. CHEVY REFUSES TO PAY FOR THE REPAIR OF $500. THERE ARE SEVERAL OTHERS WITH THIS SAME PROBLEM. I HAVE FOUND MANY WEBSITES. THIS IS AND HAS BEEN AN ONGOING PROBLEM. WE NEED A RECALL. THIS IS FOR TRAILBLAZERS WITH THE YEARS OF 2003-2005. I AM NOT GETTING MY PROBLEM FIXED AND I AM SURE THERE ARE MANY OTHER INSTRUMENT CLUSTERS THAT DO NOT WORK ON THE HIGHWAY. GM LOST A LAWSUIT FOR THE EXACT SAME YEAR VEHICLES FROM 2003-2005 FOR THE SUBURBAN, TRUCKS, TAHOES ETC. MY VEHICLE IS ALSO CONSIDERED A TRUCK AND I AM SURE THAT SAME CHEAP PART WAS USED IN MY VEHICLE. THIS IS DEFINITELY A PROBLEM PART THAT NEEDS TO BE RECALLED. PLEASE HELP! *TR

I HAVE A 2004 CHEVROLET TRAILBLAZER. THE SPEEDOMETER, THE FUEL GAUGE AND THE TACHOMETER NO LONGER WORKS ON THIS VEHICLE. WHEN I CALLED THE CHEVROLET CUSTOMER SERVICE CENTER, TO CHECK FOR A RECALL, I WAS TOLD THAT THERE WAS NO RECALL FOR THE TRAILBLAZER. THERE WAS HOWEVER A RECALL FOR THE EXACT SAME PROBLEM ON THE CHEVROLET AVALANCHE, TAHOE AND SUBURBAN. I JUST CANT UNDERSTAND WHY CHEVROLET WILL NOT RECALL THE TRAILBLAZER FOR THE EXACT SAME PROBLEM. MY SPEEDOMETER SOMETIMES REGISTERS TO THE POINT OF SEEING NO NUMBERS ON THE NEEDLE. THE GAS GAUGE RARELY REGISTERS THAT I EVEN HAVE ANY GAS. I HAVE TO KEEP UP WITH MY GAS MANUALLY AND WITH MY TRIP ODOMETER. I FIND THIS VERY DISTURBING THAT CHEVROLET WILL NOT RECALL THE TRAILBLAZER. WHAT CAN I DO AS A CONSUMER TO HELP CHEVROLET MAKE THIS OBVIOUS PROBLEM RIGHT? *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.
EA07009 · Fuel Pump Module Leaks Gasoline
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.
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.
