2005 Chevrolet Trailblazer

SPEEDOMETER GIVES AN INACCURATE READING OR SOMETIMES STOPS WORKING ALTOGETHER. THIS PROBLEM BEGAN 2-3 WEEKS AGO AND FROM OTHER TRAILBLAZER OWNERS THAT I HAVE DISCUSSED THIS WITH ONLINE IT IS A VERY COMMON PROBLEM. I DIDN'T REALIZE THAT THE SPEEDOMETER WAS FUNCTIONING IMPROPERLY UNTIL IT BECAME VERY OBVIOUS - IT WAS REGISTERING 30 MPH WHEN I WAS TRAVELING WITH THE FLOW OF TRAFFIC ON AN INTERSTATE FREEWAY. WHEN THE VEHICLE HAS BEEN TURNED OFF AND SITS FOR A WHILE, THE SPEEDOMETER SEEMS TO RESET ITSELF AND WORKS PROPERLY AGAIN FOR A WHILE, THEN THE PROBLEM BEGINS AGAIN. FROM WHAT MY RESEARCH INDICATES, IT IS A BAD STEPPER MOTOR THAT CAUSES THE PROBLEM, WHICH REQUIRES SPECIALIZED TOOLS AND EXPERTISE TO REPLACE. THE COST IS IN THE HUNDREDS OF DOLLARS. GIVEN THAT THIS IS SUCH A COMMON PROBLEM AND COMPROMISES THE SAFETY OF THE VEHICLE, I STRONGLY FEEL THAT THIS ISSUE SHOULD BE ADDRESSED BY NHTSA. THANK YOU.*CN

I OWN A 2005 CHEVY TRAILBLAZER AND I HAVE ENCOUNTERED NUMEROUS PROBLEMS SINCE PURCHASING THIS VEHICLE BRAND NEW FROM THE DEALER. I HAVE HAD TO HAVE SENSORS REPLACED, FUEL TANK HAS HAD TO BE WORKED ON, AND NOW THE MAIN MOST COSTLY IS I AM HAVING TO REPLACE THE TRANSMISSION. THIS VEHICLE HAS APPROX. 84,000K MILES ON IT AND IS ONLY TWO YEARS OLD. PLEASE HELP TO SEE IF THIS SHOULD HAVE BEEN A FACTORY RECALL. I HAVE ALWAYS HAD MY VEHICLE SERVICED AT THE DEALER WHERE I PURCHASED IT AT. *TR
