2008 Mercedes Benz S Problems, Complaints & Recalls

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.

Risk: 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.

Fix: 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.

Problem: 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.

Risk: The presence of this moisture in combination with the thermal stress during the "reflow soldering" may damage the transistors and prevent them from properly functioning which will increase the risk of crash.

Fix: Dealers will inspect and replace all potentially affected sam free of charge. The recall began on may 2, 2008. Owner may contact mercedes benz at 1-800-367-6372.
