Electrical system
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.
Air bags
Problem: Certain passenger vehicles equipped with sport model steering wheels fail to comply with the requirements of federal motor vehicle safety standard no. 208, "occupant crash protection." in certain low risk air bag deployment tests conducted by nhtsa, using an out-of-position unbelted 5th percentile female crash test dummy, irregularities were demonstrated indicating that occupants may not be properly protected in a crash.
Risk: In the event of a crash, an occupant may not be properly restrained which could result in injuries.
Fix: Dealers will install a new air bag inflator module free of charge. The recall began on march 15, 2006. Owners may contact mercedes-benz at 1-800-367-6372.
