2004 MERCEDES BENZ SL500 Electronic Stability Control Esc Problems

DUE TO DETERIORATION OF THE WIRING HARNESS CONNECTION OR FAILURE OF THE HYDRAULIC PUMP, THE SENSOTRONIC BRAKE CONTROL (SBC) SYSTEM MAY DEFAULT TO THE HYDRAULIC BACK-UP MODE. IN THE BACK-UP MODE, THE DRIVER HAS BRAKING POWER SUFFICIENT TO STOP THE VEHICLE, BUT GREATER BRAKE PEDAL PRESSURE IS REQUIRED AND BRAKE PEDAL TRAVEL WILL BE NOTICEABLY LONGER. DEALERS WILL INSTALL A BRACKET AND REPLACEMENT GROUND WIRE TO THE SBC PUMP UNIT ON ALL AFFECTED VEHICLES. ADDITIONALLY, DEALERS WILL INSPECT AND REPLACE THE SSC PUMP UNIT IN CERTAIN SL MODELS. THE MERCEDES-BENZ RECALL NUMBERS ARE 2005070007 AND 2005110001. RESEARCH SHOWS ONLY 59% OF THE 100% REQUIRED RECALL WAS DONE PROPERLY BY AN AUTHORIZED DEALER. THIS ISSUE WAS NOT DISCLOSED WHEN I PURCHASED THIS CAR AND, THE REQUIRED WORK WAS NOT DONE AND, MERCEDES SAID THE 60 DAYS FROM RECALL HAD PASSED - YET THE REPORTS SENT TO NHTSA BY MERCEDES BENZ APPEARS...
