Is your car affected?
Check by VIN to confirm the
exact model and see every recall for it.
Recalls are issued for a make, model and model year. Whether the repair has already been done on one specific car is known only to its manufacturer and dealers. Check your vehicle's official status at nhtsa.gov/recalls or with a dealer.

Electrical system
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 and remedy
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.
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.
Service brakes, hydraulic
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.
Risk and remedy
Risk: 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.
Service brakes, hydraulic
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.
Risk and remedy
Risk: 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.

Certain vehicles equipped with Active Body Control (ABC) the sensors on the front struts may not operate within tolerances. As such, the sensor signal may not be accurately transmitted to the Electronic Control Unit (ECU). A variation in the transmitted values can result in one front strut adjusting to a value while the other does not adjust and presenting the driver with an uneven front suspension. This situation could have an effect on the vehicle's directional stability, possibly resulting in a vehicle crash with injuries or death. Correction: Dealers will inspect and replace affected AZ-sensors

On certain vehicles, the Sensotronic Brake Control (SBC) unit may contain a pump piston which is out of permissible tolerances. Also, vibrations within the electrical connector may cause a loss of electrical continuity. Both conditions may result in the system reverting to hydraulic function mode. A loss of brake power assist would result in increased pedal effort and extended stopping distance. Correction: Dealers will inspect and, if required, replace the SBC pump unit.

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. DaimlerChrysler AG has determined that in certain instances, 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. Correction: Dealers will re-program the SBC hydraulic unit. A software update will provide a clear maintenance notice on the vehicle display and assure continuous pump speed operation within tolerances.
