I HAVE A 2005 CHEVY TRAILBLAZER THAT'S WARRANTY JUST EXPIRED. IN THE LAST SEVERAL DAYS AFTER GETTING GAS THE GAS SENSOR LIGHT AND SOUND ALERT STAYS ON EVEN AFTER I COMPLETELY FILL THE TANK. IN RESEARCHING THE PROBLEM ONLINE I HAVE FOUND OUT THAT THIS IS A WIDESPREAD PROBLEM WITH THIS VEHICLE, AND THAT IT IS VERY COSTLY TO REPAIR. THIS VEHICLE IS MARKETED AND USED AS A FAMILY CAR, WHICH IS WHAT MY WIFE AND I USE IT FOR. IT IS VERY RISKY TO TRY TO GUESS HOW MUCH FUEL YOU ARE USING, NOT TO MENTION THE COST OF FUEL TODAY. I HAVE HEARD OF SEVERAL INCIDENTS OF PEOPLE RUNNING OUT OF GAS IN RISKY SITUATIONS LIKE ON THE INTERSTATE. AS A CONSUMER I WISH YOU WOULD INVESTIGATE THIS SITUATION, AND IF IT IS AS WIDESPREAD AS I AM HEARING, ENCOURAGE THE MANUFACTURER TO ISSUE A RECALL FOR SAFETY PURPOSES. *TR

IN REGARDS TO MY COMPLAINT #1030331, DP10-001 REGARDING MY COMPLAINT OF MY FUEL SENSOR AND GAUGE ALWAYS READING EMPTY AND THE FACT THAT THIS HAS BEEN GOING ON FOR OVER A YEAR ON MY 2005 CHEVROLET TRAILBLAZER, I DIDN"T HAVE THE VIN NUMBER AT THE TIME. I WOULD LIKE TO PROVIDE IT TO YOU AT THIS TIME IN YOUR FORM. PLEASE ADD IT TO MY PREVIOUS COMPLAINT. THIS IS A SERIOUS PROBLEM THAT SEEMS TO BE PREVALENT IN SEVERAL YEARS OF THE TRAILBLAZERS EXISTENCE AND COULD BE A VERY DANGEROUS SITUATION ESPECIALLY IF THE COMPUTER DECIDES TO SHUT THE TRUCK DOWN AT AN INOPPORTUNE TIME. I READ WHERE NISSAN IS RECALLING ONE OF THEIR MODELS BECAUSE OF THE FUEL GAUGE. WHERE IS GM IN THIS MATTER? *TR

I HAVE A 2005 CHEVY TRAILBLAZER LS AND I HAVE TWO COMPLAINTS REGARDING PART DEFECTS THAT SHOULD BE INVESTIGATED. 1. THE SPEEDOMETER STICKS. I CAN BE DRIVING ALONG AND ALL OF A SUDDEN MY SPEEDOMETER IS NOT MOVING AT ALL. THIS IS EXTREMELY DANGEROUS BEING THAT I HAVE NO CLUE HOW FAST OR SLOW I'M GOING. 2. THE FUEL LIGHT GAUGE/SENSOR JUST COMPLETED STOP WORKING. THE GAS NEEDLE DOES NOT MOVE AT ALL, I HAVE NO IDEA HOW MUCH FUEL IS IN THE TANK. THIS IS ALSO EXTREMELY DANGEROUS!. I HAVE MANY FRIENDS THAT OWN CHEVY TRAILBLAZERS WHO HAVE ENCOUNTERED THESE SAME ISSUES AND I FEEL THAT CHEVY SHOULD FIX THE PROBLEM. I HAVE ALSO READ MANY BLOGS ONLINE WHERE TRAILBLAZER OWNERS ARE COMPLAINING OF THE SAME ISSUES SO THIS IS CLEARLY A PROBLEM FOR THOUSANDS OF TRAILBLAZER OWNERS. I HOPE THAT THIS COMPLAINT WILL HELP JUMP START AN INVESTIGATION OF THESE DEFECTS, BECAUSE IT IS A MAJOR PROBLEM! I HAVE CONTACTED MY LOCAL CHEVY DEALER AND THEY STATED THAT IT WILL BE $1,200 TO FIX THIS ISSUE.. THIS IS OUTRAGES BEING THAT THE PROBLEM IS SOMETHING THAT WAS CAUSED BY CHEVY. *TR
FUEL JUST STOPPED WORKING, DRIVING DOWN THE ROAD AND HEADLIGHTS START DIMMING GAUGES GO ALL OVER THE BOARD. PUT A NEW BATTERY IN, CHANGED THE ALTERNATOR AND IT CONTINUES TO DO THIS. CHECK ENGINE LIGHT KEEPS COMING ON FOR OXYGEN SENSOR HAD THAT REPLACED 1 YEAR AGO NEEDS REPLACED AGAIN. *TR
2005-2006 CHEVY TRAILBLAZER EXPERIENCING PROBLEM W/ THE FUEL SENSOR. WHEN THE GAS TANK IS FILLED THE CAR IS TELLING ME THERE IS NO FUEL IN THE TANK, AND THE GAUGE READS EMPTY. *TR
MY FUEL GAUGE IS NOT WORKING ON MY 2005 TRAILBLAZER AND THE BLOWER RESISTOR WENT ON MY TRUCK AS WELL. IT WENT FROM NO HEAT BLOWING ON LEVEL 5 TO THE ENTIRE THING NOT WORKING. *TR
FILLED TANK WITH GAS & THE FUEL LIGHT CAME ON AND READS EMPTY. THIS HAS HAPPENED TWICE, FIRST TIME IN NOVEMBER 2009. I STALLED AT AN INTERSECTION. THE 2ND TIME WAS FEB 28, 2010. THE NEEDLE FLUCTUATES AND LOW FUEL LIGHT FLICKERS ON/OFF. I DON'T HAVE THE MONEY TO HAVE THIS PROBLEM FIXED. *TR
FUEL GAUGE STARTED FUNCTIONING ERRATICALLY - WOULD GO FROM EMPTY TO FULL OR JUST START GOING BETWEEN FULL AND EMPTY FLOATING AROUND. EVENTUALLY IT JUST STAYED ON EMPTY EVEN WHEN I HAD JUST FILLED UP. FROM THE TIME THE PROBLEM STARTED TILL IT STOPPED WORKING WAS ONLY A MATTER OF WEEKS. NOW MY OIL GAUGE STOPPED WORKING ALSO. *TR
Official recalls
206V417000 · Air Bags:frontal
Oct 31, 2006
CERTAIN VEHICLES ORIGINALLY BUILT WITH CLOTH SEATS THAT WERE EQUIPPED WITH AN AUTOMATIC AIR BAG PASSENGER SENSING SYSTEM AND LATER REUPHOLSTERED WITH AFTERMARKET LEATHER SEAT COVER KITS ARE INVOLVED. TESTING HAS INDICATED THAT THE AFTERMARKET LEATHER SEAT COVERS CAN CAUSE THE PASSENGER SENSING SYSTEM TO MALFUNCTION.
Consequence & remedy
Consequence: IF THE PASSENGER SENSING SYSTEM MALFUNCTIONS, THE FRONT AIR BAG ON THE PASSENGER SIDE MAY BE DISABLED WHEN IT SHOULD BE ENABLED, OR ENABLED WHEN IT SHOULD BE DISABLED. IN EITHER CASE, IN THE EVENT OF A CRASH THAT REQUIRES AIR BAG DEPLOYMENT, A FRONT PASSENGER'S LEVEL OF INJURY MAY BE INCREASED.
Remedy: BECAUSE A REPLACEMENT LEATHER SEAT COVER THAT IS COMPATIBLE WITH THE PASSENGER SENSING SYSTEM IS NOT AVAILABLE, GENERAL MOTORS (GM) WILL REPURCHASE THESE VEHICLES IN ACCORDANCE WITH THE TERMS STATED IN GM'S LETTER TO OWNERS. THE RECALL BEGAN ON NOVEMBER 6, 2006. OWNERS SHOULD CONTACT GM AT 1-877-477-1022 TO BEGIN THE PROCESS OF REPURCHASING THEIR VEHICLE.

2RQ17002 · 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.
