NHTSA Complaint #10676330 — 2004 CHEVROLET TRAILBLAZER

I PURCHASED A 2004 CHEVY TRAILBLAZER LT IN FEBRUARY 2013. THAT WINTER I STARTED EXPERIENCING ISSUES WITH MY SPEEDOMETER NEEDLE RISING ABOVE WHATEVER SPEED I WAS GOING. I TOOK A PICTURE OF IT SAYING I WAS DRIVING 120 MPH WHEN I CLEARLY WASN'T. SO I DID MY RESEARCH AND FOUND THAT THOUSANDS OF OTHER CHEVY TRAILBLAZER OWNERS WERE EXPERIENCING THE SAME PROBLEM!! I CALLED CHEVYS CUSTOMER CARE LINE AND THE REPRESENTATIVE CLAIMED THIS WAS HER FIRST TIME HEARING ABOUT THIS AND THERE IS NOTHING THEY CAN DO TO HELP ME. I CONTACTED THEM VIA FACEBOOK AND STILL NOT WILLING TO HELP. AS OF RIGHT NOW MY SPEEDOMETER DOESN'T WORK. I HAVE TO USE AN APP ON MY PHONE TO KNOW HOW FAST I'M GOING. I CAN'T AFFORD TO SPEND THE $500-$800 THAT IT WOULD COST TO REPAIR SOMETHING THAT IS A MALFUNCTION ON CHEVYS BEHALF!! I JUST DON'T UNDERSTAND HOW THEY'RE GETTING AWAY WITH THIS WHEN THOUSANDS OF OTHER CUSTOMERS HAVE THE SAME PROBLEM!! I WILL NEVER BUY ANOTHER CHEVY OR GM AGAIN!! *TR
