Due to deterioration of the wiring harness connection or failure of the hydraulic pump, the sensotronic brake control (SBC) system may default to the hydraulic back-up mode. In the back-up mode, the driver has braking power sufficient to stop the vehicle, but greater brake pedal pressure is required and brake pedal travel will be noticeably longer. Dealers will install a bracket and replacement ground wire to the SBC pump unit on all affected vehicles. Additionally, dealers will inspect and replace the SSC pump unit in certain SL models. The Mercedes-Benz recall numbers are 2005070007 AND 2005110001.
The hose clamp used to secure the power steering fluid hose at the cooler may not provide sufficient clamping force, resulting in a power steering fluid leak. Loss of power steering fluid can damage the power steering pump and may result in diminished power steering assist, which could lead to a crash. Dealers will replace the power steering hose clamp to correct this concern. The Mercedes-Benz recall number is 2005 050004.
High mileage combined with a high number of brake actuations, or a high brake actuation frequency, can cause the pump motor of the SBC to run out of permissible tolerances. As a result, excessively high pressure may build the high pressure line of the brake system. If this occurs, the system will switch into the hydraulic function mode as designed. Sensotronic brake control is disabled when the brake system is functioning in the hydraulic mode. Dealers will inspect the SBC hydraulic unit and replace it if necessary to correct this concern. The Mercedes-Benz recall number is 2004 050014.

Dealers will install new blower motor fuse holders. This recall began during October 2004. The Mercedes-Benz recall number is 2004 070010.

This recall is expected to begin on December 22, 2003. The Mercedes-Benz recall number is 2003 120006.
