RECEIVED WARNING ON DASH TO CHECK REAR DRIVER TAIL LIGHT. TOOK THE CAR IN TO THE DEALER TO GET IT CHECKED OUT AND WAS TOLD THE WIRES FROM THE TAIL LIGHT WERE MELTED FROM THE ELECTRICAL PANEL AND MY CAR IS RUNNING ON BACK UP LIGHTS. THE ONLY SOLUTION IS TO REPLACE THE ENTIRE ELECTRICAL BACK LIGHT SYSTEM SINCE THE MELTED WIRES WOULD EVENTUALLY DAMAGE THE ENTIRE BRAKE LIGHT SYSTEM. THE COST TO REPAIR $900. CAR SMELLS BURNT INSIDE, AND IN THE TRUNK. I AM AFRAID OF A FIRE, AND GETTING REAR ENDED IF MY BRAKE LIGHTS STOP WORKING. *TR

AS I WAS STOPPED AT A RED LIGHT BOTH MY WIFE, KIDS AND MYSELF SMELLED A STRONG ODOR IN THE CABIN OF THE CAR. IT WAS WORSE TOWARDS THE BACK SEAT WHERE THE KIDS WERE. I IMMEDIATELY PULLED OVER AND GOT THE FAMILY OUT OF THE VEHICLE (MERCEDES BENZ C300 2008) AND SAW THAT GREY SMOKE WAS COMING OUT OF THE TRUNK OF THE CAR. WHEN I OPENED THE TRUNK I NOTICED THAT THE SMOKE WAS COMING OUT OF THE RIGHT TAIL LIGHT. THE CABLE THAT FEEDS ELECTRICITY TO THAT PANEL SHORTED AND CAUSED A SMALL FIRE WHICH TURNED OFF THE MINUTE I SHUT THE VEHICLE DOWN. I THEN TRIED PULLING OUT THE CABLE FROM THE LIGHT PANEL AND IT DID NOT BUDGE BECAUSE IT MELTED AND FUSED TOGETHER WITH THE LIGHT PANEL. *TR

THE BRAKE LIGHT (DRIVER SIDE) WAS MALFUNCTIONING AND GIVING MULTIPLE INDICATOR WARNINGS ON THE DASH COMPUTER. AFTER CHECKING TO SEE IF IT WAS A FAULTY BULB... THE HARNESS CONNECTING TO THE TAILLIGHT HOUSING WAS BURNT AND MELTED. THE TAILLIGHT BULB HOUSING WAS BRITTLE AND WAS BURNT AS WELL. THE DEALERSHIP SAID THEY KNOW OF NO SUCH RECALLS AND ARE REPLACING THE TAILLIGHT BULB HOUSING AND REPLACING THE BURNT HARNESS. (435.00) THEY ALSO SAID THAT THE COMPUTER MODULE IS BAD BECAUSE IT IS TELLING THE BRAKE LIGHT TO STAY ON. THEY ARE NOT SURE WHICH OCCURRED FIRST. THIS IS ANOTHER 1000.00 REPAIR. I HAVE RESEARCHED THIS ISSUE ONLINE AND THERE ARE MANY OTHER MERCEDES C-SERIES VEHICLES HAVING THE SAME ISSUE. MOST EXPERTS THINK THE GAUGE OF THE WIRING IS NOT ACCEPTABLE TO THE LOAD OF CURRENT. THIS IS A SAFETY HAZARD AND IS NOT LOOKING LIKE AN ISOLATED INCIDENT. THANK YOU FOR YOUR SUPPORT ON THIS MATTER. *TR

RANDOMLY I STARTED RECEIVING CHECK BULB MESSAGES FOR THE REAR LIGHTS ON BOTH SIDES OF MY CAR. I DIDN'T THINK MUCH OF IT AS I DON'T THINK THEY HAD EVER BEEN CHANGED SO I CHANGED THEM AND ALL WAS FINE AND THEN A FEW WEEKS LATER THE MESSAGES STARTED TO POP UP AGAIN. I RECHECKED THE BULBS TO MAKE SURE THEY WERE SECURELY IN PLACE AND THEY WERE SO I STARTED DOING A LITTLE RESEARCH AND DISCOVERED THAT THIS WAS A KNOWN ISSUE. PRESENTLY THE ENTIRE LEFT REAR SIDE IS OUT AND IT LOOKS LIKE THE WIRING HAS OVERHEATED AND BEEN SINGED (LOOKS LIKE IT HAD BURNED).WHEN CALLING ALL THE LOCAL SOUTHERN CALI DEALERSHIPS (ORANGE COUNTY/LONG BEACH) NONE OF THEM WILL ADMIT TO IT BEING A WIDESPREAD PROBLEM AND FIXING IT FOR FREE BECAUSE THE PARENT COMPANY, MERCEDES BENZ, HASN'T YET. I HAVE NO DESIRE TO PAY FOR A PROBLEM THAT SHOULD HAVE NEVER OCCURRED IN THE FIRST PLACE. MY MAJOR CONCERN IS ABOUT POTENTIAL FIRES IN THE TRUNK DUE TO THIS. ALL IT WILL TAKE IS ONE SPARK TO CATCH ON SOMETHING IN THE TRUNK AND THEN WELL CAR IS ON FIRE. AS MUCH A MERCEDES BENZ CLAIMS TO BE ABOUT SAFETY, I'M SHOCKED, ONE AT THE DESIGN FLAW AND TWO THAT THEY ARE GOING THROUGH THE MOTIONS OF PRETENDING LIKE THE THOUSANDS OF OWNERS WHO HAVE REPORTED THIS ARE MAKING IT UP. THEY NEED TO GET ON THIS ASAP. *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.

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

MULTIPLE SYSTEM WARNINGS ON DASH SAYING TO CHECK RIGHT REAR TAIL LIGHT, BRAKE LAMP, AND SIGNAL LIGHT. UPON REPLACEMENT OF LIGHT BULBS, NOTICED THAT THE GROUND WIRE CABLE COVERING WAS MELTED AS WELL AS BURNS AND MELTING ON THE BULB HOUSING UNIT. ALL RIGHT REAR LIGHTS WORKED INTERMITTENTLY OR DIMLY AND NOW DON'T WORK AT ALL. NOW, THERE ARE SYSTEM WARNINGS FOR LEFT REAR LIGHTS AS WELL. THIS IS A SAFETY ISSUE AS A FIRE CAN START IN THE TRUNK OF THE CAR AS WELL AS HAVING REAR LIGHTS WORKING INTERMITTENTLY OR NOT AT ALL WITH NO WARNING. VEHICLE IS NO LONGER UNDER WARRANTY AND AUTHORIZED DEALERSHIP WON'T REPAIR AT NO CHARGE UNLESS THERE IS A RECALL. THIS IS A KNOWN ISSUE WITH THESE VEHICLES, BY BOTH THE MANUFACTURER AND AUTHORIZED DEALERS. RECALL SHOULD BE ISSUED. *TR

WARNING MESSAGE DISPLAYED IN INSTRUMENT PANEL ADVISING TO CHECK REAR RIGHT HAND SIDE MARKER LIGHTS, ON INITIAL INSPECTION IN THE TRUCK THEIR WAS A SMELL OF BURNING PLASTIC EMIGRATING FROM THE RIGHT HAND SIDE REAR LIGHT CLUSTER ON REMOVAL OF THE FUSE PANEL COVER AND INSPECTION THE WIRES WHICH CONNECT THE WIRING HARNESS TO THE LIGHTING BACKPLATEI I WAS UNABLE TO HOLD THE CONNECTOR WITH A NAKED HAND DUE TO THE EXCESSIVE TEMPERATURE. AFTER LEAVING THINGS TO COOL DOWN FOR 60 MINUTES I WAS ABLE TO REMOVE THE WIRING HARNESS CONNECTOR FROM LIGHTING CLUSTER BACK PLATE TO FIND THAT THE EARTH PIN (BROWN WIRE EXTREME RIGHT HAND SIDE ) WAS MELTED AND ALSO THE PIN TO WHICH IT MATED TOO HAD ALSO BEGAN TO MELT THE PLASTIC WHICH SUPPORTED THE PIN ON HE LIGHTING BACK PLATE. THE EARTH (BROWN WIRE) IS OF AN EXTREMELY LOW GAUGE FOR THE POTENTIAL LOAD THIS WIRE WOULD POTENTIALLY NEED TO CARRY UNDER MAXIMUM LOAD (ALL LIGHTS LIT). *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
