Defect. 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. 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.

Defect. 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. 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.

Defect. 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. 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.

MY WIFE WAS DRIVING ABOUT 1/2 MILE FROM OUR HOUSE WHEN THE BRAKES COMPLETELY FAILED. SHE WAS ON A BACK ROAD AND HAD TO BRAKE FOR A STOP SIGN. SHE WAS ABLE TO PULL OFF ON THE SIDE OF THE ROAD, TO AVOID REAR ENDING A CAR STOPPED AT THE STOP SIGN, AND FINALLY BRING THE CAR TO A STOP. THE BRAKES STARTED TO WORK WITH ABOUT 1" OF PEDAL FROM THE FLOOR. SHE SAID IT WAS SO HARD TO PUSH ON THE PEDAL THAT SHE COULD BARELY DO IT. LUCKILY SHE WAS NOT HURT. HAD THIS HAPPENED ON A MAJOR ROAD OR HIGHWAY THE RESULTS COULD HAVE BEEN CATASTROPHIC. APPARENTLY THIS WAS THE FIRST YEAR FOR A NEW BRAKING SYSTEM REFERRED TO A "DRIVE BY WIRE". EURO MOTORCARS IN MD INFORMED ME THAT BECAUSE MERCEDES HAD SO MUCH TROUBLE WITH THIS NEW SYSTEM THAT THEY EXTENDED THE WARRANTY FOR THIS PROBLEM FOR 10 ADDITIONAL YEARS. THE NEW EXTENDED WARRANTY ON THIS BRAKE FAILURE ISSUE WAS FOR COMPLETE PARTS AND LABOR. I WAS NEVER NOTIFIED OF THIS EXTENDED WARRANTY. NO ONE AT THE DEALERSHIP, WHERE I HAVE HAD THE CAR SERVICED EXCLUSIVELY, NOTIFIED ME OF ANY WARRANTY EXTENSION FOR THIS VERY SERIOUS BRAKING FAILURE ISSUE. I FIND THIS REPREHENSIBLE! MY WIFE COULD HAVE KILLED. WHY WAS SUCH A SERIOUS BRAKING ISSUE NOT MADE A RECALL INSTEAD OF "IF YOU HAVE A PROBLEM WARRANTY EXTENSION"? AT THE VERY LEAST MERCEDES SHOULD HAVE RECALLED ALL CARS WITH THIS POTENTIAL BRAKING FAILURE. THE PROBLEM LIES WITH THE SBC HYDRAULIC BRAKING UNIT. THE CAR WAS TOWED TO EURO MOTORCARS WHERE IT WAS REPAIRED. I ASKED THE SERVICE WRITER IF IT COULD BE

NO INCIDENT. WAS DRIVING AND AS I PULLED INTO MY DRIVEWAY, HEARD BUMPING SOUND FROM CAR. ASKED MERCEDES WHAT IT WAS, THEY SAID LOOSE BAFFLE IN GAS TANK. SOUNDS LIKE MANUFACTURING DEFECT. CHECKED ONLINE AND FOUND MANY OTHERS WITH SAME PROBLEM. IT IS A COSTLY REPAIR JUST OUTSIDE OF WARRANTY PERIOD. *TR

I PURCHASED A 2003 MERCEDES BENZ SL500 IN DECEMBER OF 2003. AS OF TODAY 8 NOVEMBER 2005, THE SUSPENSION APPARENTLY CAN NOT BE REPAIRED. THE CAR HAS BEING TAKEN BACK TO THE DEALER FOR THE EIGHT (8TH) TIME TO REPAIR THE SUSPENSION. IT IS CURRENTLY ALEXANDRIA VIRGINIA, MERCEDES BENZ AS OF NOVEMBER 9TH, 2005. WHILE DRIVING THE VEHICLE HOME FROM A DINNER ENGAGEMENT, LATE OCTOBER 2005, ONE OF THE FRONT HYDRAULIC SHOCK DROPPED AND THE VEHICLE LITERALLY CHANGED LANES. FORTUNATELY, NO CARS WERE BESIDE ME AT THE TIME. I AM WRITING TO THE NHTSA TO GET THEIR ASSISTANCE IN DETERMINING THE FEASIBILITY OF DRIVING THIS VEHICLE WITH ITS UNPREDICTABLE LEVEL OF SAFETY. I AM APPALLED BY MERCEDES BENZ LACK OF CONCERN TO REPLACE THIS VEHICLE, THE MANUFACTURER OR THEIR REPRESENTATIVES, ARE UNABLE TO REPAIR IT. I REQUEST YOUR ASSISTANCE TO DETERMINE MY NEXT STEPS OR ANY ACTIONS YOU CAN TAKE TO COMPEL THE MANUFACTURER TO RESOLVE THIS MATTER. *JB

I TURNED KEY AND CAR DID NOT START. I ENDED UP GETTING STUCK EITHER AT HOME OR IN A SHOPPING CENTER. CAR HAD TO BE PUT ON A FLAT BED. DEALER RELPACED PARTS EACH TIME , BUT COULD NOT FIND THE CAUSE OF THE PROBLEM.

2003 MERCEDES BENZ SLK 320 EXPERIENCING PROBLEMS WITH HESITATION WHEN THE ACCELERATOR IS DEPRESSED.*MR ON ONE OCCASIONS WHEN THE CONSUMER ATTEMPTED TO APPLY THE GAS THE VEHICLE DID NOT MOVE FOR A FEW SECONDS AND THEN ALL OF A SUDDEN THE VEHICLE LURCHED FORWARD AND THE CONSUMER HIT ANOTHER VEHICLE. THE THERE WAS ALSO A RATTLE IN THE EXHAUST. *JB

THE VEHICLE (2003 MB SLK320) WAS PURCHASED ON 4/14/2004 IN AZ AND BEGAN NOTICING PROBLEMS ON THE DRIVE BACK TO NM. THE MOST SIGNIFICANT SAFETY PROBLEM INVOLVES THE TRANSMISSION, WHICH HAS BEEN SERVICED BY THE MANUFACTURER 8 TIMES WITHOUT RESOLUTION. THE VEHICLE SLIPS IN AND OUT OF GEAR AT HIGHWAY SPEEDS. THE VEHICLE HAS SPENT A TOTAL OF OVER 68 DAYS IN THE SHOP FOR UNSATISFACTORY REPAIRS IN A ONE-YEAR PERIOD. TO THIS DATE, THE MANUFACTURER HAS BEEN UNCOOPERATIVE IN RESOLVING THESE PROBLEMS FORCING ME TO SEEK LEGAL SERVICES.*AK

HYDRAULIC BRAKE FAILURE, TOTALLY UNEXPECTED. CAR IS A MARCEDES BENZ SL500, 2003. ONLY 8,500 K. ON 6-24-04, MB ISSUED A SAFETY BULLETIN (NHTSA CAMPAIGN ID NO. 04V296000)MB HAS NOT NOTIFIED OWNERS LIKE ME. I RUN A 4-WAY STOP SIGN AND A LARGE PICK-UP TRUCK WAS WITHIN 1 OR 2 FEET FROM HITTING ME ON THE DRIVERS' SIDE. IWAS ABLE TO STOP THE CAR ABOUT 50 YARDS AFTER THE STOP SIGN. MESSAGGE --IN RED LETTERS IN THE DASHBOARD-- WICH SAID "REDUCED BRAKE EFFECT. VISIT WORKSHOP".. I WAS NOT INJURED PHYSICALLY, BUT THIS WAS A NEAR DEATH EXPERIENCE. THIS HAPPENED ON 7-26-04. THE DEALER HAS PRACTICALLY CONFICATED THE CAR AND REFUSES TO SAY MUCH. MB SENT A TECHNICIAN FROM HEADQUARTERS TO CHECK THE CAR BUT REFUSED TO TALK TO ME. NEEDLES TO SAY THEY ARE EVASIVE AND DENY THERE IS A PROBLEM. ONLY GOING TO THE INTERNET IA FOUN THAT I AM NOT THE ONLY ONE AFFECTED, HAVING, BY CHANCE FOUND THE INFORMATION ABOUT THE DEFECT. LUCKILY THERE WAS NO INJURIES, BUT I WANT TO REPORT THIS FRO TW REASONS. NO.1: WHY MB DID NOT NOTIFY ME OF THIS DEFECT. IT IS NOW CLEAR THAT THE SENSOTRONIC BRAKE CONTROL THIS CAR USES IS DEFECTIVE, BECAUSE IT REQUIRES ELECTRICAL ENERGY. ACCORDING TO THE CARS' MANUAL (PAGE 260),THE SBC WILL GO INTO THE EMERGENCY OPERATION MODE AND BRAKES ARE ONLY APPLIED TO THE FRONT TIRES, STOPPING DISTANCE IS INCREASED AND THE DRIVER HAS TO BE DEPRESSED ALMOS TO THE FLOOR. IN MY CASE I ALMOST STOOD UP TO APPLY PRESSURE AND WENT DOWN TO SECOND GAER ON THE TRAMNSMISSION, BEFORE THE CAR STOPPED. NO.

IN THE RIGHT DOOR PANEL THERE IS A GLUE THAT SEALS THE PANELS TOGETHER. THIS GLUE GIVES OFF TOXIC FUMES. CONSUMER'S WIFE IS CURRENTLY SEEING A NEUROLOGIST FOR PROBLEMS SUFFERED FROM INHALING THE FUMES. THE MANUFACTURER AND THE DEALER HAVE BEEN NOTIFIED.*AK

THE HEATER MOTOR HAD BLOWN OUT. THE VEHICLE BOX CAUGHT ON FIRE. *AK THE FIRE MELTED THE MELTED THE WIRING HARNESS. *SCC *JB
