NHTSA Complaint #10225326 — 2003 CHEVROLET TRAILBLAZER

THE VEHICLE TRANSFER CASE HAS FAILED TWICE. THE FIRST FAILURE OCCURRED AT 33,377 MILES. THE DEALER REPAIRED THE VEHICLE UNDER THE VEHICLE ORIGINAL WARRANTY. THE SECOND FAILURE OCCURRED WITH 43,971 MILES. (MILES PER EACH TRANSFER CASE)THE VEHICLE WAS IDLING ROUGH AND IN 4WD. I SELECTED THE AWD MODE AND THE VEHICLE MADE A CLUNKING SOUND BUT STOPPED IDLING ROUGH. WHEN I TRIED TO PUT IT BACK IN 4WD IT WOULD NOT GO INTO THE 4WD MODE. WHEN I RETURNED HOME I TRIED TO PUT THE VEHICLE IN 4 LOW AND IT WENT INTO 4 LOW BUT WOULD NOT COME OUT OF 4 LOW. THE SERVICING DEALER AND GM CLAIM THE TC FAILURE IS BECAUSE WE LIVE IN A NORTHERN STATE AND THEREFORE USE THE AWD AND 4WD MORE THAN OTHER REGIONS. I SPOKE WITH ANOTHER DEALER AND THEY CLAIM GM IS AWARE OF THIS PROBLEM, BUT CANNOT FIX IT. THE SECOND DEALER SAID THEY COULD REPAIR THE VEHICLE, BUT ASSURED ME THAT THE TC WOULD FAIL AGAIN. BOTH DEALER SAID THEY SEE THESE TRAILBLAZER TC FAILING ALL WINTER LONG. THERE WERE ABOUT 4 TO 5 TRAILBLAZERS IN THE SERVICE DEPT (NOT INCLUDING OURS) WITH BROKEN TRANSFER CASES. *TR
