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

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. 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

ABSOLUTELY NOTHING OUT OF THE ORDINARY, REGULAR DRIVING CONDITIONS. THE SPEEDOMETER ON MY 2005 CHEVY TRAILBLAZER DOES NOT WORK. IT IS CONTINUOUSLY READING THE WRONG SPEED AND SKIPS WHEN MOVING. IT WILL GO ALL THE WAY TO 120MPH AND THEN BEYOND WHEN I KNOW I AM ONLY GOING 50. AT 55 TO 65 MILES AN HOUR THE SPEEDO STICKS THEN CONTINUES TO CLIMB. THE ONLY WAY I HAVE FIGURED OUT HOW TO CHANGE IT BACK IS TO TURN ON AND OFF THE VEHICLE UNTIL IT RESETS BACK TO 0. THIS TAKES FOR EVER AND IS DAMAGING TO THE VEHICLE. IT ONLY GOES BACK 4 MPH AT A TIME WHENEVER I HAVE TO DO THIS. IT HAPPENS ALMOST EVERYDAY NOW AND I AM LIVID WITH MY VEHICLE. I WILL NEVER BUY A GMC AGAIN. *TR
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.
CERTAIN SPORT UTILITY VEHICLES FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 212, 'WINDSHIELD MOUNTING.' THE WINDSHIELD URETHANE BEAD MAY NOT HAVE ADHERED TO THE BODY IN CERTAIN AREAS DURING THE CURE PROCESS.
Consequence & remedy
Consequence: IF A CRASH OCCURS, THE WINDSHIELD MAY NOT BE RETAINED, INCREASING THE RISK OF INJURY TO A VEHICLE OCCUPANT.
Remedy: DEALERS WILL REPLACE THE WINDSHIELD FREE OF CHARGE. THE RECALL BEGAN ON MARCH 10, 2005. OWNERS MAY CONTACT BUICK AT 1-866-608-8080, CHEVROLET AT 1-800-630-2438, OR GMC AT 1-866-996-9463.

RQ17002 · 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.
