I HAVE A 2005 CHEVY TRAILBLAZER LT AND LIVE IN BIRMINGHAM, AL. ON MY WAY HOME FROM CHURCH ON A SUNDAY MORNING, I ENCOUNTERED A SEVERE ISSUE WITH MY SPEEDOMETER. AS I WAS DRIVING UP ON A POLICE OFFICER I LOOKED AT MY SPEEDOMETER, WHICH SAID I WAS DOING 70 SO I BEGAN SLOWING DOWN BUT MY SPEEDOMETER DIDN'T - IT CONTINUED TO GO UP. I STARTED HITTING MY BRAKES THINKING THAT WOULD MAKE THE SPEEDOMETER GO BACK DOWN BUT IT DIDN'T. AS I PULLED OFF THE INTERSTATE AND STOPPED AT A RED LIGHT, THE SPEEDOMETER KEPT GOING UP TO 110 MPH. THEN AS THE LIGHT TURNED GREEN, I STARTED AGAIN AND THE SPEEDOMETER WENT STRAIGHT TO THE BOTTOM FACING THE FLOOR. I THOUGHT WHEN I GET HOME AND TURN THE CAR OFF, THE SPEEDOMETER WOULD RESET ITSELF. WELL ... IT DIDN'T!! I DON'T KNOW WHAT I'M GOING TO DO NOW! THE ECONOMY IS SO !@#$% BAD THAT I'M IN THE MIDDLE OF A FORECLOSURE AND NOW THIS CRAP HAPPENS! GM SHOULD RECALL THIS FAULTY ISSUES AS IT IS A DANGEROUS SITUATION. IF YOU DON'T KNOW HOW FAST YOU ARE GOING ... HOW THE !@#$% DO YOU DRIVE WITHOUT A SPEEDOMETER UNLESS YOU ARE LOOKING TO GET IN TROUBLE BY THE LAW!! *TW

THE SPEEDOMETER ON MY 2005 CHEVY TRAILBLAZER MALFUNCTIONED SAYING I WAS GOING FASTER THAN I REALLY WAS. THIS HAS HAPPENED 3 TIMES; THE FIRST TIME ON JANUARY 28TH 2010, AND TWICE ON THE NIGHT OF FEBRUARY 4TH 2010. IT APPEARS TO BE GETTING WORSE EACH TIME. THE SPEEDOMETER WILL INCREASE DURING ACCELERATION AND NOT MOVE FOR DECELERATION. WITH EACH DECELERATION AND SUBSEQUENT ACCELERATION THE SPEEDOMETER CONTINUES TO INCREASE UNTIL YOU HIT MAX SPEED OF 120 MPH. THIS IS A LARGE DANGER FOR FREQUENT FREEWAY/HIGHWAY TRAVELING CONSIDERING THE VEHICLES APPROACHING FROM THE REAR AND I HAVE NO WAY OF KNOWING HOW FAST MY VEHICLE IS REALLY GOING. THE ONLY WAY THAT I HAVE FOUND TO RESET THE SPEEDOMETER, IS TO STOP AND SHUT OFF THE VEHICLE, THEN RESTART THE VEHICLE. HOWEVER, THIS MUST BE DONE MULTIPLE TIMES, SOMETIMES UP TO 10 TIMES OR MORE. EACH TIME THE VEHICLE IS SHUT OFF AND RESTARTED, THE SPEEDOMETER WILL RESET APPROXIMATELY 5 MPH. THIS EVENING I HAD TO RESTART MY TRUCK 12 TIMES TO GET IT BACK TO ZERO. THE FIRST TIME THIS HAPPENED, A FRIEND WAS DRIVING FOR ME, AND THIS MALFUNCTION HAS RESULTED IN A SPEEDING TICKET. *TR

AFTER FILLING MY GAS TANK, THE GAS GAUGE NEEDLE DROPPED PAST "E". IT RECOVERED SOMEWHAT AND A FEW DAYS LATER, BACK TO "E". THE NEEDLE ONLY SOMETIMES MOVES PAST "E", EVEN WHEN FULL, AND NEVER GOES MORE THAT THE 1/4 MARK. I'VE UNKNOWINGLY RUN OUT OF GAS TWICE. FIRST OCCASION I WAS ON A DARK ROADSIDE BUT HAD SOMEONE NEARBY TO HELP. THE MOST RECENT OCCASION I WAS ON A HIGHWAY, STALLED PARTIALLY IN TRAFFIC. IT WAS 5 DEGREES OUTSIDE AND THE CLOSEST ROADSIDE ASSISTANCE PROVIDER WAS OVER AN HOUR AWAY. *TR
1. DRIVING ON THE HIGHWAY, MINDING MY BUSINESS... 2. SPEEDOMETER IS STUCK AT 0 WHEN I'M DRIVING, SAYS I'M GOING 100+ WHEN I'M AT A STANDSTILL, & IS NEVER ACCURATE ANY MORE. HAPPENS EVERY TIME I DRIVE NOW. ALREADY ONE SPEEDING TICKET- 55 IN A 40 AND I HAD NO IDEA. 3. NOTHING DONE YET- DEALER SAYS COST WILL BE $500+. *TR
I OWN A 2005 CHEVY TRAILBLAZER. ON HIGHWAY 61 NEAR TROY, MO, THERE IS A SPEED RADAR SET ALONG THE ROAD TO DISPLAY VEHICLE SPEED TO DRIVERS.

I OWN A 2005 CHEVY TRAILBLAZER. ON HIGHWAY 61 NEAR TROY, MO, THERE IS A SPEED RADAR SET ALONG THE ROAD TO DISPLAY VEHICLE SPEED TO DRIVERS. ON 2 OCCASIONS, MY SPEEDOMETER SHOWED SPEEDS OF 60 MPH WHEN THE RADAR DISPLAY SHOWED 40 TO 45 MPH AND ON 3 OCCASIONS, MY SPEEDOMETER INDICATED SPEEDS OF 60 (THE SPEED LIMIT), WHILE THE RADAR DISPLAYED SPEEDS ANYWHERE FROM 75 TO 85 MPH. I WAS GOING 15 TO 25 MPH FASTER THAN THE SPEED LIMIT, BUT DID NOT KNOW IT ACCORDING TO MY SPEEDOMETER. THIS DOES NOT HAPPEN ALL THE TIME, BUT HAS OCCURRED AT LEAST 6 OR 7 TIMES OVER THE PAST YEAR AT DIFFERENT LOCATIONS. I HAVE FOUND THAT WHEN I STOP THE TRAILBLAZER, WHEN THE SPEEDOMETER IS REGISTERING LOW, THE SPEEDOMETER NEEDLE WILL ACTUALLY MOVE BELOW THE 0 MPH. ON THOSE OCCASIONS WHEN MY SPEEDOMETER WAS REGISTERING HIGH, WHEN I HAVE STOPPED THE VEHICLE, THE NEEDLE WILL STILL BE SHOWING 25 TO 40 MPH! MY FEAR IS THAT ON ONE OF THOSE OCCASIONS THAT MY SPEED IS ACTUALLY FASTER THAN INDICATED, MY SPEED MY CAUSE AN ACCIDENT. I HAVE FOUND THAT AFTER STOPPING THE CAR AND TURNING IT OFF, IF I JUST TURN THE IGNITION KEY TO RUN WITHOUT STARTING IT SEVERAL TIMES, THE NEEDLE WILL GRADUALLY RESET ITSELF BACK TO 0 AND I WON'T HAVE ANY MORE PROBLEMS FOR A WHILE. I HAVE HAD AN ESTIMATE TO REPLACE THE INSTRUMENT CLUSTER FOR $500 TO $600, BUT I FEEL THIS IS A RECALL PROBLEM THAT CHEVROLET NEEDS TO TAKE CARE OF. I HAVE READ NUMEROUS COMPLAINTS FROM OTHER TRAILBLAZER OWNERS ON THE INTERNET, THIS IS WHAT MOVED ME TO FILE THIS COMPLAINT. *TR
HEADLIGHTS DIM GREATLY WHEN THE TEMPERATURE IS IN THE 30S OR BELOW. TOOK THE CAR IN FOR SERVICE AT A CERTIFIED CHEVROLET REPAIR CENTER ONLY TO BE TOLD THAT IT IS NORMAL. *TR
2005 CHEVROLET TRAILBLAZER FUEL GAUGE STOPPED WORKING. FILLED CAR WITH GAS GAUGE READS EMPTY. NO WAY TO KNOW NOW WHEN I AM OUT OF GAS. CAR ALSO HAS A DISTINCT GAS SMELL. *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.
