Check Brakes if Sensotronic Brake Control (SBC) Light Comes on on Mercedes-Benz SL500

Problem Description and Possible Solution

This vehicle has sensotronic brake control (SBC). If the SBC light on the dash illuminates, have the brakes checked. If the SBC is not working, limited brake pressure is delivered to the front brakes, increasing the distance it takes to stop. The SBC hydraulic unit has a specific service life programmed into the control module; follow the manufacturer's recommended service procedure for proper maintenance of the SBC.

Red stop light on the left hand side. And brake malfunction on the right side lites up on the instrument cluster whats wrong ????
Technicians found bad batteries and bad SBC (failed accumulator). Total repair cost $2400. This has not even begun to fix the convertible hard top problems, or the random turning on of the 4-way flashers.
Stop sign on left side, warning message Brake failure on right side, forces car to downshift and come to stop. Told by local repair shop that this is a known issue that should be covered by MB, but local dealership says no.
