20170722SERVICE BRAKES
THIS VEHICLE IS EQUIPPED WITH SENSOTRONIC BRAKE CONTROL THAT HAS A SERVICE THRESHOLD. WHEN THIS THRESHOLD IS REACHED THE BRAKE SYSTEM DEFAULTS TO NON POWER ASSISTED HYDRAULIC MODE TO THE FRONT WHEELS ONLY. THIS OCCURS WITHOUT ANY PRIOR WARNING AND RESULTS IN INCREASED STOPPING DISTANCE. I HAVE SENT A COPY OF THE MERCEDES SERVICE BULLETIN S142.46-P-0012A WHICH ADDRESSES THIS ISSUE. MERCEDES STOPPED INSTALLING THIS SYSTEM IN 2006. AT THE VERY LEAST, MERCEDES SHOULD ISSUE A MANDATORY RECALL TO INTERROGATE THESE VEHICLES WITH STAR DAS TO DETERMINE HOW CLOSE TO THE SERVICE THRESHOLD THE SBC UNIT IS AND REPLACE THEM AT THE DEALER'S EXPENSE. THIS IS A MAJOR SAFETY ISSUE THAT NEEDS TO BE ADDRESSED EVEN IF THE AUTOMOBILE IS OLDER

I WAS COMING TO A STOP AT A TRAFFIC LIGHT IN LEFT TURN LANE. AT A VERY SLOW SPEED OF LESS THAN 5 MPH. SUDDENLY MY 2003 MERCEDES BENS SL500 STEERING BECAME DISENGAGED FROM THE FROM WHEELS. I HAD ZERO DIRECTIONAL AND TURN CONTROL OVER THE CAR. THE CAR CROSSED THE MEDIAN YELLOW LINES. AT THIS MOMENT NO CARS WERE PASSING BY IN THE OPPOSITE DIRECTION. VERY LUCKY THAT THERE WAS NO ONE TO CRASH INTO. ALSO LUCKY THE STEERING MECHANISM BROKE AT BELOW 5 MPH INSTEAD OF FWY SPEED. THE STEERING WHEEL COULD FREELY SPIN 10+ TURN IN EACH DIRECTION, WHILE FRONT WHEELS DIRECTION WAS COMPLETELY UNCHANGED. *TR

THE FAILURE AND THE CURRENT MILEAGE WAS 59,000.
