Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 15 investigation files overlapping the 2003 SL500R. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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

TL* THE CONTACT OWNS A 2003 MERCEDES BENZ SL500R. THE CONTACT STATED THAT WHILE ATTEMPTING A RIGHT TURN, THE VEHICLE EXHIBITED A LOUD METAL NOISE. THE VEHICLE WAS TOWED TO THE LOCAL MECHANIC WHO PERFORMED A DIAGNOSTIC AND LOCATED THE FAILURE AS THE FRONT PASSENGER SIDE STRUT SENSOR FAILING. THE FAILURE CAUSED THE FRONT PASSENGER SIDE END TO LIE ON TOP OF THE TIRE. THE MANUFACTURER WAS CONTACTED AND DENIED ANY ASSISTANCE WITH THE REPAIRS BECAUSE THE VEHICLE WAS NOT INCLUDED IN NHTSA CAMPAIGN ID NUMBER: 08V405000 (SUSPENSION). THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND THE CURRENT MILEAGE WAS 59,000.
