Consumer Description

THIS VEHICLE WOULD GO OUT OF GEAR WITHOUT WARNING BECAUSE OF A FAULTY 4 WHEEL DRIVE SWITCHING SYSTEM. THIS OCCURRED IN TRAFFIC, AND AN UNOCCUPIED PARK SITUATION. THE VEHICLE WENT OUT OF PARK AND ROLLED INTO A DOOR WHILE IN THE GARAGE. THE VEHICLE ALSO WENT OUT OF GEAR IN TRAFFIC SITUATIONS CAUSING THE DRIVER TO FIND THE ROAD SHOULDER. IF THE DRIVER MANIPULATED THE SWITCH IT WOULD SOMETIMES RE-ENGAGE THE TRANSMISSION. AN ENCODER MOTOR SENSOR WAS REPLACED, THEN FAILED IN TWO WEEKS. IT WAS THEN DIAGNOSED THAT THE ENCODER MOTOR WAS FAULTY AND CAUSING THE ENCODER SENSOR TO FAIL. REPLACED MOTOR AND SENSOR AGAIN. THIS IS A DEFECT THAT SHOULD BE PART OF THE EXISTING RECALL FOR ALL 2002 CHEVROLET TRAILBLAZERS, NOT JUST THE SELECT FEW AS PRESCRIBED TODAY. *TR
