NHTSA Complaint #10164873 — 1999 GMC SIERRA

ABS CONTROL UNIT MODULE ACTIVATED WHILE DRIVING ,CAUSING ABS VALVE TO RUN CONTINUOUSLY & BURN UP. DEALER STATED THAT CAUSE OF FAILURE WAS DUE TO CORROSION GETTING INTO MODULE UNIT. DEALER REPLACED MODULE,VALVE & BLED BRAKE SYSTEM. COST WAS $1090. SERVICE MANAGER STATED THAT THIS WAS A RECURRING PROBLEM THAT GM KNEW ABOUT BUT NO RECALL WAS ISSUED TO FIX THE PROBLEM AT THAT TIME. ACCORDING TO NHTSA WEB SITE , GM HAS ISSUED A RECALL FOR WHEEL SENSORS ON THIS VEHICLE DUE TO THE SAME CAUSE AS THE MODULE FAILURE; CORROSION. THE MODULES ARE LOCATED JUST BELOW DRIVER ON THE INSIDE OF THE FRAME RAIL. HOW THEY EXPECTED TO KEEP THEM FROM A CORROSIVE ENVIRONMENT ,I CAN'T FIGURE. IT SEEMS TO ME THAT IF GM ACKNOWLEDGE A CORROSION PROBLEM ON ONE PART OF THEIR ABS SYSTEM THAT THEY SHOULD DO THE SAME ON THE ENTIRE SYSTEM. I ALSO CAN'T UNDERSTAND HOW THEY CHOOSE CERTAIN STATES AS BEING IN THE "SALT BELT". WE USE IT HERE IN KANSAS TOO. *JB
