NHTSA Complaint #10297869 — 2004 CHEVROLET TRAILBLAZER

THE PROBLEMS THAT ARE HAPPENING TO MY 2004 CHEVY TRAILBLAZER : I AM HAVING A WHINING NOISE IN THE FRONT END OF THE VEHICLE AND WHEN I TRY TO ENGAGE INTO 4WD THE SOUND WORSENS AND THERE IS A VIBRATION IN THE FRONT AS WELL THE WHINING ALMOST RESEMBLES A LOW SIREN SOUND. I AM ALSO HAVING A MAJOR MALFUNCTION WITH MY SPEEDOMETER SINCE THE WEATHER HAS GOTTEN COLDER??? I COULD ONLY BE MOVING 10MPH AND IT WILL REGISTER TO 120 OR EVEN SURPASS IT AND THEN GET STUCK, THE ONLY WAY TO UNSTICK IT IS TO SHUT THE CAR OFF AND KEEP RESTARTING IT UNTIL IT RESETS ITSELF BUT NOW IT IS STUCK AND WONT RESET, I WENT ONLINE TO SEE IF THERE WERE ANY RECALLS AND I ALL I FOUND OUT WAS THERE WERE TONS OF PEOPLE HAVING THE SAME ISSUES WITH THEIR TRAILBLAZERS AS I AM HAVING. THESE PROBLEMS ARE OCCURRING AT ALL DIFFERENT TIMES DURING THE LIFE OF THE CAR SOME PEOPLE HAVE THEM HAPPEN AROUND 30,000 MILES OR SOME 50 THOUSAND AND MYSELF THE SPEEDOMETER IS HAPPENING AROUND 72,000 MILES. THE SPEEDOMETER SEEMED TO START TO ACT UP ONCE THE WEATHER WAS COLDER. ITS A SHAME THEY WILL FIX THE LARGER SUV'S DUE TO A LAWSUIT BUT SINCE THIS IS A SMALLER SUV IT'S NOT COVERED. WE HAVE TRIED TO REPLACE THE WHEEL BEARINGS IN THE TRUCK FOR THE FRONT END NOISE TO ONLY FIND THE NOISE DID NOT DISAPPEAR AFTER READING MANY OF OTHER COMPLAINTS FROM OTHERS IT SEEMS THIS COULD BE THE TRANSFER CASE ON THE TRUCK. I AM NOT GOING TO KEEP REPLACING PART AFTER PART TO ONLY FIND OUT ITS THE DRIVE TRAIN AND SOMETHING SHOULD BE DONE ABOUT THIS. *TR
