NHTSA Complaint #10336249 — 2002 CHEVROLET TRAILBLAZER

WHENEVER BRAKING AND SLOWING DOWN ALMOST TO A STOP, THE ANTI-LOCK BRAKE SYSTEM (ABS) WILL ENGAGE. VEHICLE MAKES THE TYPICAL ABS "CHATTER" SOUND WHEN THIS OCCURS AND THE ABS ENGAGEMENT CAN BE FELT IN THE BRAKE PEDAL. ROAD CONDITIONS ARE CLEAN AND DRY; ROAD SURFACE IS LEVEL AND NOT BUMPY. ONLY OCCURS WHEN SPEED IS BELOW APPROXIMATELY 10MPH (FOR INSTANCE, WHEN COMING TO A STOP AT A STOPLIGHT, STOPSIGN, OR BRAKING ON A LEVEL DRIVEWAY). AS A RESULT, BRAKING DISTANCE IS EXTENDED AT THE VERY TIME THE VEHICLE SHOULD BE COMING TO A STOP -- EVENTUALLY, A COLLISION IS INEVITABLE. THIS STARTED APPROXIMATELY 2-WEEKS AGO, OCCURRING RARELY BUT NOW OCCURS ABOUT 30% OF THE TIME. BRINGING THE CAR TO THE LOCAL CHEVY DEALER SERVICE DEPARTMENT TOMORROW MORNING (6/15/2010) TO EXAMINE THE PROBLEM. NOTE THAT THE VEHICLE HAD A COMPLETE BRAKE JOB AT THE SAME CHEVY DEALER SERVICE DEPARTMENT ON 2/10/2010. *TR
