NHTSA Complaint #10596875 — 2003 CHEVROLET TRAILBLAZER

I HAVE A 2003 TRAILBLAZER THAT HAS A SPEEDOMETER THAT DOES NOT WORK CORRECTLY, ON THE HIGHWAY THE SPEEDS VARY AND SOMETIMES SHOW THAT IT IS GOING 0 MILES FOR HOURS OTHER TIMES IT WILL SHOW DIFFERENT SPEEDS SUCH AS 35 OR 45 WHILE DRIVING AT THE SAME SPEED OF TRAFFIC WHICH IS 70 MPH. THE OIL PRESSURE GAUGE IS STUCK BEYOND THE HIGHEST LEVER AND AT INTERMITTENT TIMES THE TACHOMETER DOES NOT WORK. THERE IS ALSO AN ISSUE WITH THE HEATING AND COOLING FAN WHERE THE FAN WILL NOT BLOW AT ALL AND YOU HAVE TO SHUT THE CAR DOWN AND RESTART IT TO GET THE FAN TO BLOW AT ALL. THE AC AND HEAT ARE ALSO NOT CHANGING IN TEMPERATURE AT ALL. I HAVE READ MANY COMPLAINTS ABOUT THE SPEEDOMETER AND INSTRUMENT CLUSTER AND FIND IT RIDICULOUS THAT THERE HAS NOT BEEN A RECALL PUT FORTH ON THIS, ESPECIALLY TO ENSURE MOTORISTS ARE TRAVELING AT THE CORRECT SPEEDS ENSURING THE SAFETY FOR ALL AND THAT GM HAS NOT OFFERED ANY TYPE OF RECALL FOR THE TRAILBLAZER BUT HAS ON DIFFERENT MODELS WITH THE SAME PROBLEM IN THE SAME MODEL YEARS. *TR
