2001 Mercedes Benz S500

WHILE DRIVING ON THE FREEWAY, THE BACK LIGHTS IN THE INSTRUMENT CLUSTER THAT ILLUMINATE THE SPEED MARKINGS STARTED TO FLICKER FOR A FEW SECONDS AND THEN TURNED OFF AND WENT DARK. THEN AFTER A FEW MINUETS, THE WHOLE INSTRUMENT CLUSTER WENT DARK AND THE SPEEDOMETER STOPPED WORKING COMPLETELY. IT WAS IMPOSSIBLE TO KNOW WHAT SPEED YOU ARE GOING AT. *TR

RIGHT FRONT END CONTINUOUSLY LOWERING FOR MONTHS. TRIED FILTERING ABC FLUID AND CHANGING FILTERS SEVERAL TIMES, FINALLY PUMP FAILED AND REQUIRED REPLACING AT $4,000. OEM PUMP ONLY AVAILABLE. AFTER REPAIR, ADVISED THAT THE VALVE BLOCK MAY STILL NEED REPLACING FOR AN ADDITIONAL $4,000. ALSO NOTICED THAT THE FRONT RIGHT SPRING CONTROL ARM RUBBER MOUNT WAS CRACKED AND GRINDING AGAINST THE FRONT SUBFRAME. SERVICE DEPARTMENT RECOMMENDED BOTH ARMS AND SUBFRAME REPLACED AT A COST OF AROUND $3,000. SINCE THE CAR IS NO LONGER VALUED AT THIS TOTAL EXPENSE, I ORDERED PARTS ON-LINE AND MET A FRIEND TO REPAIR BOTH FRONT CONTROL ARMS AS RECOMMENDED. JUST PRIOR TO MAKING THIS REPAIR, MY FRIEND IDENTIFIED A TECHNICAL SERVICE BULLETIN (ORDER # P-B-33. 15/12C/12D, DATED 4 SEPT 2008) ISSUED BY MERCEDES TO REPAIR THIS CONTROL ARM AND RECOMMENDED TO CONTACT MERCEDES TO FIX AT NO CHARGE. TWO MERCEDES DEALERSHIPS WERE UNFAMILIAR WITH THE TSB, TOLD ME THAT THERE WERE NO CURRENT OUTSTANDING RECALLS OR WARRANTY ISSUES, AND THAT IT WAS PROBABLY NOT A COVERED REPAIR. HOPING SOMEONE CAN ADVISE IF THIS CONTROL ARM REPLACEMENT IS COVERED BY MERCEDES. *TR

WHILE OPERATING THE VEHICLE ON A TWO LANE DIVIDED HIGHWAY, THE VEHICLE WOULD NOT UP-SHIFT GEARS AND GOT STUCK IN THIRD GEAR WHILE I WAS ATTEMPTING TO PASS A TRACTOR TRAILER WITH OTHER VEHICLES BEHIND ME ATTEMPTING TO DO THE SAME. SUBSEQUENTLY, I MANAGED TO MANEUVER THE VEHICLE TO A PARKING LOT TO EXAMINE THE ISSUE. I COULD NOT FIND ANYTHING EXTERNALLY WRONG WITH THE VEHICLE THAT WOULD STAND OUT IN A VISUAL INSPECTION. NEXT, I TURNED THE IGNITION OFF AND TURNED IT BACK ON, FORCEFULLY PUT THE CAR IN GEAR, AND FOUND THAT IT WOULD NOT SHIFT OUT OF FIRST GEAR. VEHICLE HAD TO BE TOWED OVER 150 MILES TO A SHOP. THE PROBLEM STEMS FROM THE DESIGN AND MATERIALS USED FOR THE TRANSMISSION WIRING HARNESS THAT ENABLES TRANSMISSION FLUID TO WICK UP THE WIRING HARNESS FROM THE BOTTOM OF THE VEHICLE UP INTO THE TRANSMISSION CONTROL UNIT THAT IS ENCASED IN PLASTIC AND LOCATED UNDER THE HOOD. AS IMPOSSIBLE AS IT SOUNDS, TRANSMISSION FLUID TRAVELS UP THIS BUNDLE OF WIRES AND POOLS IN THE ENCASEMENT DISRUPTING THE ELECTRONIC CIRCUIT BOARD THAT CONTROLS THE TRANSMISSION. EQUALLY CONFUSING, THE ELECTRIC CURRENT FROM THE WIRES PULLS THE TRANSMISSION FLUID UP THE WIRING HARNESS. I CAN'T IMAGINE WHY THIS DESIGN OR MATERIALS WOULD BE UTILIZED ON THIS OR ANY OTHER CAR KNOWING WHAT THE ULTIMATE OUTCOME WOULD BE FOR CONSUMERS, $$$$$$$!!!!!!!!!!!! *TR

TL* THE CONTACT OWNS A 2001 MERCEDES BENZ S500. THE CONTACT STATED THAT THE INSTRUMENT PANEL MALFUNCTIONED AND CAUSED THE GAUGES AND WARNING INDICATORS TO STOP WORKING. AN INDEPENDENT MECHANIC STATED THAT THE INSTRUMENT PANEL NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED AND THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS UNKNOWN. UPDATED 10/03/14*LJ UPDATED 05/12/2015 *JS

WHILE DRIVING ON A 400 MILE TRIP HOME IN THE DARK, THE ENTIRE CLUSTER LIGHTING TURNED OFF AND SPEEDOMETER BEGAN TO FLUCTUATE. THE SITUATION WAS EXTREMELY HAZARDOUS AND I WAS FORCED TO PULL OVER ON A MAJOR HIGHWAY TO FIND OUT WHAT IS WRONG. AS NO FUSES OR RELAYS WERE BLOWN OUT, I HAD TO USE A SMALL FLASHLIGHT TO ILLUMINATE THE CLUSTER TO GET HOME. *TR

I WAS DRIVING THE VEHICLE ON THE HIGHWAY WHEN ALL OF A SUDDEN THE ENTIRE DASH GAUGE CLUSTER FLICKERED AND WENT TOTALLY DARK AND STOPPED WORKING. I WAS SO DISTRACTED THAT I ALMOST RAN INTO THE CAR THAT WAS IN FRONT OF ME. THE INTERIOR LIGHTING WENT OUT AS WELL. NOW, THERE IS NO WAY OF KNOWING THE SPEED OF THE VEHICLE OR OF SEEING ANY OF THE OTHER IMPORTANT GAUGES INCLUDING GEAR SELECTION. IT IS IMPOSSIBLE TO DRIVE THE CAR SAFELY. THE MERCEDES DEALER IN MANHATTAN AND NORTH AMERICA MERCEDES CENTER IN NJ SAYS THE CAR IS NOT COVERED AND THAT THE EXTENDED WARRANTY FOR THIS ISSUE HAS EXPIRED. THEY HAVE BASICALLY SAID" TOO BAD" FOR ME IN A VERY ARROGANT AND COLD MANNER. ALMOST LIKE I SHOULD BE ASHAMED FOR ASKING THEM TO FIX IT. THIS IS A LOW MILES WELL CARED FOR VEHICLE THAT HAS ALWAYS BEEN PAMPERED AND GARAGED. IT BELONGED TO MY FATHER. THE ESTIMATED REPAIR PRICE FROM THE DEALER FOR THE INSTRUMENT CLUSTER IS OVER $4,000.00. THE CAR IS CURRENTLY SITTING IN MY GARAGE UNABLE TO BE DRIVEN. FRANKLY, I AM SURPRISED AT MERCEDES' REFUSAL TO FIX THE CAR CONSIDERING THAT THERE WAS A NATIONAL RECALL CONCERNING THIS VERY ISSUE AND THAT ALSO THERE WAS A NEED FOR A MB EXTENDED WARRANTY TO FIX THIS VERY SAME LIGHTING/CLUSTER ISSUE. NOT TO MENTION THE EXORBITANT PRICE FOR THE S500 BOTH RETAIL AND WHEN IT WAS NEW. I EXPECTED WHEN I PURCHASED THE CAR THAT IT WOULD PROVIDE THE TYPE OF RELIABILITY AND ENGINEERING THAT MERCEDES CLAIMS TO HAVE BUILT IT'S REPUTATION ON. *TR

THE CONTACT WAS ALSO INFORMED THAT THE VEHICLE WAS NOT INCLUDED IN THE RECALL ASSOCIATED WITH NHTSA CAMPAIGN ID NUMBER 06V028000 (INTERIOR LIGHTING). THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE, BUT OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS 112,000. UPDATED 11/03/11 *BF UPDATED 11/04/11
