THE 2003 MERCEDES BENZ E320 HAS A FAULTY GATEWAY MODULE AND SOFTWARE. THIS MODULE HAS RESULTED IN PROBLEMS BEING REPORTED IN MY CAR THAT THE BRAKES, SELF RESTRAINT SYSTEM, TELEPHONE SYSTEM, AND TIRE PRESSURE HAVE FAILED. I HAVE NO WAY OF KNOWING IF THE THE SAFTY SYSTEMS ARE OPERATIONAL OR NOT. AT THIS POINT I AM DRIVING A CAR THAT SAYS MY SRS SYSTEM IS NOT WORKING. I HAVE BEEN IN THE MERCEDES SHOP NO LESS THAN 4 TIMES TO HAVE THE PROBLEM REPAIRED. IT SIMPLY RE-OCCURS AFTER EACH REPAIR. FROM RESEARCH ON THE INTERNET, THIS APPEARS TO BE A COMMON PROBLEM.
MERCEDES-BENZ IS RECALLING MY 2006-2008 M-CLASS, R-CLASS, MY 2005-2009 SLK-CLASS, MY 2005-2008 C-CLASS, MY 2003-2004 AND 2006-2008 CLK-CLASS, MY 2003-2008 E-CLASS, MY 2004 AND 2008 CL-CLASS, MY 2008 CLS-CLASS, MY 2004 AND 2007-2008 S-CLASS, MY 2003 G-CLASS, AND MY 2003-2004, 2006 AND 2009 SL-CLASS VEHICLES. A SOFTWARE CALIBRATION NUMBER (SCN) CODING RECEIVED ON THE AFFECTED VEHICLES DURING A RECENT WORKSHOP VISIT WAS INCORRECT. DEPENDING ON THE MODEL YEAR AND MODEL AFFECTED, THE RESULTS OF AN INCORRECT SCN CODING CAN AFFECT A NUMBER OF VEHICLE SAFETY AND EMISSION FUNCTIONS INCLUDING THE FOLLOWING TYPES OF FUNCTIONS: (1) THE FUEL GAUGE READINGS MAY BE INCORRECT; (2) A STUCK FUEL-LEVEL SENSOR MAY NOT BE DISPLAYED IN THE INSTRUMENT CLUSTER; (3) THE OBD SYSTEM MAY CAUSE THE CHECK ENGINE LIGHT TO ILLUMINATE INCORRECTLY; AND, (4) THE SPEEDOMETER MAY BE OUT OF TOLERANCE.
Consequence & remedy
Consequence: IN THE EVENT OF A VEHICLE CRASH, THE ELECTRICAL FUEL PUMP MAY NOT RECEIVE A CRASH SIGNAL THAT IS REQUIRED FOR THE FUEL PUMP TO DISCONNECT AND PREVENT FUTURE FUEL DELIVERY AS DESIGNED.
Remedy: DEALERS WILL RECODE THE SCN FREE OF CHARGE. THE RECALL BEGAN ON AUGUST 30, 2008. OWNERS MAY CONTACT MERCEDES-BENZ AT 1-800-367-6372.
ON CERTAIN VEHICLES, THE SENSOTRONIC BRAKE CONTROL (SBC) SYSTEM MAY PREMATURELY SHIFT TO THE HYDRAULIC BACK-UP FUNCTION MODE, DUE TO DETERIORATION OF THE WIRING HARNESS CONNECTION, OR DUE TO PREMATURE FAILURE OF THE HYDRAULIC PUMP.
Consequence & remedy
Consequence: IN THE HYDRAULIC BACK-UP MODE, THE DRIVER HAS BRAKING POWER SUFFICIENT TO STOP THE VEHICLE, ALTHOUGH GREATER BRAKE PEDAL PRESSURE IS REQUIRED AND THE BRAKE PEDAL TRAVEL WILL BE NOTICEABLY LONGER.
Remedy: DEALERS WILL INSTALL A BRACKET AND REPLACEMENT GROUND WIRE TO THE SBC PUMP UNIT ON ALL VEHICLES FREE OF CHARGE. ADDITIONALLY DEALERS WILL INSPECT AND REPLACE THE SBC PUMP UNIT IN SL VEHICLES PRODUCED DURING A LIMITED PRODUCTION PERIOD. THE RECALL BEGAN ON AUGUST 8, 2005. OWNERS MAY CONTACT MERCEDES-BENZ AT 1-800-367-6372.
ON CERTAIN VEHICLES, THE ELECTRONIC MONITORING SYSTEM OF THE SENSOTRONIC BRAKE CONTROL (SBC) IS DESIGNED TO MONITOR THE PRESSURE GRADIENT WITHIN THE HIGH PRESSURE LINE OF THE BRAKE SYSTEM. IF AN UNACCEPTABLE PRESSURE GRADIENT IS DETECTED, THE SYSTEM WILL SWITCH, AS IT IS DESIGNED TO DO, INTO THE HYDRAULIC FUNCTION MODE.
Consequence & remedy
Consequence: IF VEHICLES ARE NOT ROUTINELY SERVICED AND HAVE EXTREMELY HIGH MILEAGE COMBINED WITH A HIGH NUMBER OF BRAKE ACTUATIONS, OR A HIGH BRAKE ACTUATION FREQUENCY, THE PUMP MOTOR OF THE SBC MAY RUN OUT OF PERMISSIBLE TOLERANCES, THEREBY TRIGGERING THE HYDRAULIC FUNCTION MODE.
Remedy: DEALERS WILL INSPECT THE SBC HYDRAULIC UNIT, REPLACING IT IF NECESSARY. THE RECALL BEGAN ON OCTOBER 21M 2004. OWNERS SHOULD CONTACT MERCEDES-BENZ AT 1-800-367-6372.
ON CERTAIN PASSENGER VEHICLES, THE NUT ON THE BOLT WHICH CONNECTS THE STEERING GEAR TO THE STEERING COUPLING MAY NOT BE TIGHTENED CORRECTLY.
Consequence & remedy
Consequence: THE LOOSENING OF THE NUT COULD RESULT IN A SLIPPING OF THE CONNECTION OVER TIME, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL INSPECT THE VEHICLES AND TIGHTEN THE NUT ON THE BOLT IF NECESSARY. OWNER NOTIFICATION BEGAN AUGUST 21, 2003. OWNERS SHOULD CONTACT MERCEDES-BENZ AT 1-800-367-6372.
