NHTSA Complaint #10455210 — 2002 GMC SONOMA

WHILE BRAKING FOR A YIELD INTERSECTION ON 3/30/2012, APPROX. 10AM, IN DRY AND CLEAR CONDITIONS, BRAKES ON 2002 GMC SONOMA FAILED. VEHICLE WOULD NOT STOP DESPITE HARD PRESSURE ON THE BRAKE PEDAL AND RAN THROUGH INTERSECTION ALMOST COLLIDING WITH ANOTHER VEHICLE. WHEN MANAGED TO GET VEHICLE STOPPED AND PULLED TO SIDE OF ROAD, BOTH THE ABS AND BRAKE FAILURE WARNING LIGHTS WERE ILLUMINATED ON THE DASH. UPON TURNING THE IGNITION OFF AND RESTARTING, BOTH THE ABS AND BRAKE FAILURE WARNING LIGHTS CLEARED AND WERE NO LONGER ILLUMINATED. CHECK ENGINE LIGHT NEVER ILLUMINATED. TOOK VEHICLE TO BOTH INDEPENDENT MECHANIC AND GM DEALERSHIP MECHANIC AND BOTH CONFIRMED AN ODB II TROUBLE CODE OF C0265 HAD BEEN GENERATED. THIS CODE, I WAS TOLD, INDICATES FAILURE OF THE EBCM (ELECTRONIC BRAKE CONTROL MODULE) OF THE ABS SYSTEM. APPARENTLY, THIS PROBLEM IS WELL-KNOWN TO GM AND IT HAS ISSUED SEVERAL TECHNICAL SERVICE BULLETINS ON THE PROBLEM, BUT NO RECALLS. INDEPENDENT MECHANIC COULD NOT REPLACE THE EBCM AS LACKED THE PROPRIETARY GM SOFTWARE NEEDED TO PROGRAM IT. GM DEALERSHIP MECHANIC--WHILE CONFIRMING GENERATION OF THE C0265 TROUBLE CODE--REFUSED TO REPLACE THE EBCM INSTEAD SAYING I SHOULD "JUST DRIVE IT AROUND AND SEE IF THE PROBLEM HAPPENS AGAIN." THIS SEEMED A VERY DISMISSIVE APPROACH BY GM TO A KNOWN PROBLEM ON CERTAIN OF THEIR ABS VEHICLES AS THE FIRST BRAKE FAILURE ON 3/20/2012 ALMOST CAUSED A WRECK. NOT ANXIOUS TO FIND OUT WHAT THE SECOND FAILURE THE GM DEALER WANTS ME TO "WAIT FOR" WOULD RESULT IN. *TR
