AFTER I TOOK MY 2008 MERCEDES C350 TO THE DEALERSHIP TO HAVE THEM DO THE REPAIRS FOR THE RECALL ON THE TAIL LIGHTS/BULBS. I KEEP GETTING THE "CHECK RIGHT REAR TURN SIGNAL". THE BLINKER WILL WORK FINE, THEN AFTER 10 MINUTES OF DRIVING IT BLINKS VERY FAST AND THE WARNING LIGHT COMES ON. THIS ISSUE IS GETTING WORSE. THIS IS AN EXTREME SAFETY HAZARD AND MUST BE FIXED IMMEDIATELY. PLEASE ADVICE! EVERYTHING APPEARED TO BE WORKING FINE UNTIL I GOT MY VEHICLE BACK FROM THE SERVICE DEPT. THEY CHANGED THE BULBS. *TR

THE TAIL LIGHT AND BLINKERS OUT AND I AM GETTING SEVERAL ERROR MSGS. ON MY DASHBOARD STATING THERE IS AN ISSUE WITH MY LIGHTS. I CANNOT DRIVE MY CARE WITHOUT LIGHTS ARE IT IS A SAFETY ISSUE AND LEGAL ISSUE. *TR I TOOK MY CAR INTO WALTERS MERCEDES BENZ IN RIVERSIDE LAST WEEK. I WAS TOLD THAT THE ISSUE IS CAUSED BY A MELTED ELECTRICAL CONNECTOR . I CALLED MERCEDES BENZ USA CORPORATE AND WAS ASSIGNED TO [XXX](REGIONAL CASE MGR). HE TOLD ME THEY ARE NOT AWARE OF THIS ISSUE AND DUE TO THE FACT THAT MY CAR IS OUT OF WARRANTY I WILL HAVE TO PAY FOR THE $500 REPAIR. NEEDLESS TO SAY, I AM NOT HAPPY WITH PAYING FOR A REPLACEMENT OF A FACTORY DEFECTED PART. I WOULD GREATLY APPRECIATE IT IF YOU LOOK INTO THIS ISSUE. THANK YOU. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

CHECK RIGHT TAILLIGHT INDICATOR APPEARED ON DASH. REAR RIGHT LIGHTS OUT. INSPECTED TO FIND ALL BULBS WERE OPERATIONAL BUT WIRE HAD OVERHEATED AND MELTED INTO HOUSING. *TR

AFTER PARKING MY C350 I NOTICED SMOKE COMING FROM THE TRUNK ON THE PASSENGER SIDE. I OPENED THE TRUNK TO DISCOVER THE SOURCE OF THE SMOKE WAS THE TRUNK FUSE BOX PANEL. I REMOVED THE PANEL AND FOUND THAT THE TAILLIGHT ASSEMBLY WAS SMOKING. FOLLOWING THE REMOVAL DIRECTIONS IN THE OWNER'S MANUAL, I REMOVED THE MULTI-PIN CONNECTOR AND NOTICED THAT THE HOUSING AROUND THE BROWN CONDUCTOR WAS COMPLETELY MELTED AND CORRODED. THERE WAS A DISTINCT SMELL OF BURNING PLASTIC. I THEN DROVE HOME WITH THE PASSENGER TAIL LIGHT ASSEMBLY DISCONNECTED FOR FEAR OF FURTHER DAMAGE OR AN ELECTRICAL FIRE. LUCKILY I WAS NOT PULLED OVER NOR DID I CAUSE AN ACCIDENT DUE TO INACTIVE BRAKE/REVERSE LIGHTS. ONCE HOME, I DETERMINED THAT THE BURNED AND CORRODED CONDUCTOR MUST BE THE GROUND CONNECTION. I BELIEVE THAT THE GROUND CABLE IN THE TAIL LIGHT HARNESS IS NOT OF HEAVY ENOUGH GAUGE TO HANDLE THE CURRENT THAT PASSES THROUGH IT UNDER NORMAL CONDITIONS. HERE IS THE MATH: EACH BULB IS 21W. IF YOU ARE AT A STOPLIGHT AT NIGHT WITH YOUR HEADLIGHTS ON AND YOU'RE TURNING RIGHT, THERE WILL BE 5 BULBS ACTIVE (PER SIDE). THIS IS A TOTAL OF 105W. AT 12V, 105W TRANSLATES TO ABOUT 9A. THE RECOMMENDED WIRE GAUGE IS 16-18 AT THIS LEVEL OF CURRENT. THE BROWN WIRE IN THE TAIL LIGHT HARNESS IS AN 18 GAUGE WIRE I BELIEVE. THIS WIRE IS RIGHT AT ITS LIMIT FOR CURRENT HANDLING. WE KNOW THAT IN THE REAL-WORLD, CURRENT CAN EASILY EXCEED THEORETICAL LIMITS, SO ENGINEERS OFTEN OVER-SPEC WIRE TO BE TOTALLY SURE THAT A CIRCUIT WILL NOT FAIL. IN THIS CASE, THE MERCEDES-BENZ ENGINEERS DID NOT OVER-SPEC THE WIRE...THEY UNDER-SPEC'D THE WIRE, AND IT FAILED! I HIGHLY RECOMMEND A RECALL, SINCE THIS IS POTENTIALLY A SERIOUS SAFETY ISSUE. A CAR COULD EASILY GO UP IN FLAMES DUE TO THIS PROBLEM. OR AN ACCIDENT COULD HAPPEN DUE TO BRAKE/REVERSE/TURNING LIGHTS THAT HAVE BURNED UP AND FAILED. *TR

I WAS DRIVING AROUND 8PM HERE IN CANADA WHEN I WAS PULLED OVER FOR A FLICKERING DRIVER-SIDE TAIL LIGHT. THE OFFICER WARNED ME THAT IT WAS A SAFETY ISSUE. MY WIFE TOLD ME AFTER DRIVING BESIDE ME THAT THE LIGHT FLICKERS INTERMITTENTLY, AND WHEN IT IS NOT, THE PARKING LIGHT ITSELF IS MUCH DIMMER THAN THE PASSENGER-SIDE TAIL LIGHT. I'VE TRIED REPLACING THE BULBS, BUT NOTHING CHANGES. AFTER DOING RESEARCH ONLINE, I'VE FOUND THAT THIS IS A COMMON ISSUE WITH 2008-2011 MERCEDES C-CLASS MODELS. I'VE FOUND THAT THE ELECTRICAL WIRING FOR THE TAILLIGHTS IS NOT SUFFICIENTLY GROUNDED, CAUSING MELTING OF THE WIRING HARNESS, AND IN SOME CASES, CAUSING A FIRE. I'VE CALLED MERCEDES DEALERSHIPS HERE IN VANCOUVER, BUT BECAUSE THE CAR IS NO LONGER UNDER WARRANTY, IT IS AN EXPENSIVE ISSUE TO FIX. IT IS ALSO A SAFETY HAZARD TO MYSELF AND OTHER DRIVERS WHEN DRIVING AT NIGHT. *TR

THE REAR LIGHTS CONTINUE TO FAIL - BRAKE LIGHTS, STOP LIGHTS, TURN SIGNALS AND BACKUP LIGHTS FAIL REPEATEDLY. THE DASHBOARD INDICATOR ANNOUNCES LIGHTS ARE OUT AND WHEN I CHECKED THE BULBS ARE INTACT BUT AND THE LIGHTS COME BACK ON BY JIGGLING THE WHOLE LIGHTING HOUSING. THEY GO OUT AGAIN AS SOON A TRAVEL RESUMES. *TR

TAIL LAMP REPLACEMENT- I GOT A RECALL LETTER 4 MONTHS AGO AND NO FURTHER INSTRUCTIONS. EMAIL TO THE DEALER AND COMPANY NOT BEING SATISFACTORILY RESPONDED TO. WHAT'S THE TIMELINE ON THESE RECALLS? *TR

THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 110,000.

FROM REVIEWING THE SITE, THIS IS THE SAME COMPLAINT YOU HAVE ALREADY HAD ABOUT THESE CARS. IT APPEARS TO ALREADY BE UNDER INVESTIGATION. IN OUR CASE, A NUMBER OF THE REAR LIGHTS, INCLUDING LIGHTS ON BOTH SIDES OF THE CAR, WENT OUT AT ONCE. THIS MEANS TURN SIGNAL LIGHTS, BRAKE LIGHTS, SIDE LIGHTS. THE FIRST CLUE WAS THAT MULTIPLE WARNINGS CAME UP ON THE DASH. WE STOPPED CAR, AND ON INSPECTION, SEVERAL LIGHTS ALSO HAD STOPPED FUNCTIONING. THE WAS NO OBVIOUS VISUAL OR OLFACTORY SIGN OF OVERHEATING OR FIRE. *TR

THE ONBOARD COMPUTER INDICATED THAT THE R REAR TURN SIGNAL HAD FAILED. VISUAL INSPECTION OF THE WIRING INSIDE THE TAIL LIGHT ASSEMBLY SHOWED THAT THE CONNECTOR FOR THE ELECTRICAL WIRING HARNESS WHICH DELIVERS POWER TO THE TAIL LIGHTS HAD MELTED. THIS CAUSED DAMAGE TO THE BULB, CARRIER, PLUG AND SOCKET PARTS. ALL NEEDED TO BE REPLACED. THIS IS A KNOWN ISSUE ON THE C CLASS MERCEDES FOR THIS MODEL YEAR. *TR
