OUR 2005 CHEVY TRAILBLAZER SPEEDOMETER JUST QUIT WORKING. WE CAN BE SITTING AT A COMPLETE STOP AND THE SPEEDOMETER WILL READ 50MPH. IT WILL RANDOMLY CHANGE AND LATER WILL EVEN DROP BELOW THE ZERO MARK. WE HAVE NO IDEA HOW FAST WE ARE TRAVELING WHEN THIS OCCURS. YESTERDAY, WHILE DRIVING FROM OH TO IN, I HAD TO GUESS HOW FAST …

OUR 2005 CHEVY TRAILBLAZER SPEEDOMETER JUST QUIT WORKING. WE CAN BE SITTING AT A COMPLETE STOP AND THE SPEEDOMETER WILL READ 50MPH. IT WILL RANDOMLY CHANGE AND LATER WILL EVEN DROP BELOW THE ZERO MARK. WE HAVE NO IDEA HOW FAST WE ARE TRAVELING WHEN THIS OCCURS. YESTERDAY, WHILE DRIVING FROM OH TO IN, I HAD TO GUESS HOW FAST I WAS GOING ON THE FREEWAY. THE SPEEDOMETER STARTED OUR READING 45MPH, SO I ESTIMATED THAT I HAD TO TRAVEL AT 110 MPH TO GO 65MPH. THE PROBLEM BECAME WORSE WHEN I NOTICED THAT MY SPEEDOMETER WAS JUMPING FROM ONE SPEED TO THE NEXT, NOT GRADUALLY CLIMBING LIKE IT SHOULD HAVE BEEN. THIS PROBLEM IS A RANDOM OCCURRENCE. I NEVER KNOW WHEN TO EXPECT IT. OBVIOUSLY, THERE ARE SERIOUS CONSEQUENCES THAT CAN ENSUE. SPEEDING TICKETS, ENDANGERING OTHERS' AS WELL AS OUR OWN LIVES BY DRIVING TOO FAST OR TOO SLOW, OR CAUSING ACCIDENTS IN GENERAL. NOTHING HAS BEEN DONE TO CORRECT THE PROBLEM SINCE THE CAR IS OUT OF WARRANTY AND I AM UNDEREMPLOYED AND WE CANNOT AFFORD TO REPLACE THE INSTRUMENT CLUSTER AT THIS TIME. *LN

I HAVE A 2005 CHEVROLET TRAILBLAZER LS EXT AND THE SPEEDOMETER, FUEL, AND BATTERY GAUGES DO NOT WORK PROPERLY. THERE IS A DIMMING OF THE LIGHTS WHILE DRIVING AND PEOPLE SOMETIMES THINK I AM FLASHING MY LIGHTS AT THEM. ACCORDING TO HTTP://FORUMS.TRAILVOY.COM/SHOWTHREAD.PHP?T=18419&HIGHLIGHT=GAS+GUAGE&PAGE=2 THIS HAS BEEN A KNOWN PROBLEM FOR SEVERAL YEARS AND NO ONE HAS DONE ANYTHING ABOUT IT. THERE ARE SEVERAL OTHER FORUMS OUT THERE THAT SAY THE SAME THING,THIS IS A MAJOR SAFETY HAZARD AND COULD CAUSE MAJOR PROBLEMS INCLUDING ACCIDENTS, SPEEDING TICKETS, RUNNING OUT OF GAS...THE PROBLEMS ARE ENDLESS I GUESS. SOMETHING NEEDS TO BE DONE. WHY HAS THERE NOT BEEN A RECALL ON THIS WITH SO MANY COMPLAINTS? ARE YOU WAITING FOR SOMETHING SERIOUS TO HAPPEN? *TR
