Mercedes-Benz USA, LLC: Safety Recalls in 2008

MERCEDES-BENZ IS RECALLING 577 MY 2008 GL-CLASS, M-CLASS, AND R-CLASS VEHICLES. A DEFECT MAY EXIST IN THE DRIVING PIN USED TO CONTROL THE OIL PRESSURE OF THE POWER STEERING.

MERCEDES-BENZ IS RECALLING 1,515 MY 2007 S-CLASS VEHICLES. THE RADIAL KNUCKLE OF THE FRONT STRUT MAY FAIL. THE RADIAL KNUCKLE FLAW MAY OCCUR AFTER SIGNIFICANT MILEAGE ACCUMULATION COMBINED WITH EXPOSURE TO HIGH CONTINUOUS STRESS BY DRIVING ON ROUGH ROADS.

MERCEDES-BENZ IS RECALLING 125,228 MY 1998-2004 M-CLASS VEHICLES. THE HOSE CLAMP USED TO SECURE THE POWER STEERING FLUID COOLING HOSE TO THE POWER STEERING FLUID COOLER MAY NOT PROVIDE SUFFICIENT CLAMPING FORCE FOR THIS CONNECTION.

MERCEDES BENZ IS RECALLING 4,564 MY 2001-2006 CL-CLASS (MODEL 215), MY 2002-2006 S-CLASS (MODEL 220), MY 2003-2007 SL-CLASS (MODEL 230), MY 2007-2008 CL-CLASS (MODEL 216), AND MY 2007 S-CLASS (MODEL 221)PASSENGER VEHICLES EQUIPPED WITH ACTIVE BODY CONTROL (ABC) ACCELERATION SENSORS ON THE FRONT STRUTS. THESE SENSORS MEASURE ACCELERATION AROUND THE Z-AXIS OF THE VEHICLE AND ASSURE AN AUTOMATIC ADAPTATION OF THE FRONT STRUTS TO MAINTAIN A RELATIVELY LEVEL BODY POSITION. VARIATIONS IN THE SOLDERING PROCESS RESULTED IN SOLDERING POINTS ON THE BOARD OF THE ABC SENSORS WHICH MAY NOT BE WITHIN DESIGN TOLERANCES. SIGNALS FROM THE AFFECTED SENSORS MEASURING THE ACCELERATION MAY NOT BE ACCURATELY TRANSMITTED TO THE ENGINE CONTROL UNIT.

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.

MERCEDES-BENZ IS RECALLING 52,740 MY 2006-2008 GL AND ML CLASS VEHICLES EQUIPPED WITH FLEX-N-GATE TRAILER HITCH. SOME OF THE WELD SEAMS CONNECTING THE TRAILER HITCH RECEIVER TO THE ATTACHMENT BAR USED TO SECURE THE TRAILER HITCH TO THE BODY FRAME DO NOT MEET PERFORMANCE SPECIFICATIONS.

MERCEDES-BENZ IS RECALLING 3,283 MY 2008 S-CLASS AND CL-CLASS PASSENGER VEHICLES. A MALFUNCTION MAY OCCUR ON THE SIGNAL ACQUISITION AND ACTUATION MODULE-FRONT (SAM-F) TRANSISTORS. THE SAM-F IS A DOUBLE TRANSISTOR THAT HELPS CONTROL VEHICLE FUNCTIONS AND THE LIGHTING OF THE CENTER CONSOLE. INCORRECT STORAGE OF THE TRANSISTORS LED THE TRANSISTORS TO BE EXPOSED TO EXCESS HUMIDITY.

ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH DIESEL ENGINES, THE CRANKSHAFT SENSOR COULD FAIL DUE TO SEPARATION OF BOND WIRES FROM THE LEAD FRAME IN THE SENSOR. THIS RESULTS IN AN INTERRUPTION IN THE ELECTRICAL CONNECTION IN THE CHIP HOUSING OF THE SENSOR.
