2010 MERCEDES BENZ C300 Exterior Lighting Problems

The vehicle had a previous warranty repair for the taillight burning out repaired but the issue has happened per the recall but the dealer states that since they fixed it then they wont fix it again even tho its what the complaint for the recall was originally

car not able to be driven rear subframe had completely rusted out and rear light housing is burn

I purchased the vehicle in 2010 & immediately had to have the electrical system for all lights replaced. The lights on the vehicle goes out every 2 mos as if theres an electrical issue. Air bags had a recall & have been replaced now the system states there is a malfunction. This started 09/08/22.

My husband drove my car home from work on April 18th 2022 and it was a bad rain storm that everyone. He had to drive through a couple of big rain storms. Soon afterwards he got around the corner from the house and the electric system failed lights started going off everywhere in the car, he lost steering and couldn’t see and almost crashed and got the car home safely but it wouldn’t shut off so he had to disconnect the battery for the car to shut off. On April 22 nd the car was towed to the dealership because it wasn’t driveable and they check out the car and discovered water under the carpeting of the drivers seat near the wiring of the car. I submitted an insurance claim and an adjuster went out to see the damage and his thought is that it’s due to a known problem for this car that’s been reported by many people with this same vehicle. The Mercedes Benz c300- 2010-2014 years. I checked online and apparently many people have reported this same issue water underneath the car due to bad firewall manufacturered not sealed correctly which could be a manufacturers/ safety issue. My husband was almost killed thank goodness he made it home safe that night. I believe there are many people that have had this issue and someone needs to be done for safety purposes, and I believe the insurance doesn’t want to cover the repairs because they are blaming Mercedes’ Benz. My cars been in the shop a month and I still have no answer from State Farm or the shop Mercedes Benz.

MERCEDES BENZ C300W LIGHT BULBS ARE CONSTANTLY BLOWING OUT. PRIMARILY DUE TO THE HEAT ACCUMULATION IN THE HEADLIGHTS. THE PLASTIC PARTS ARE MELTING, DRY AND VERY BRITTLE WHICH CAUSES BULBS TO OVERHEAT AND BLOW OUT. LEFT & RIGHT PARKING LIGHTS(4), SIDE LAMPS(2) AND LICENSE PLATE LAMP(2) HAVE BEEN CHANGED OUT AT LEAST 15 TIMES PER LAMP. THE DEALERSHIP SUGGEST I CHANGE OUT THE HEAD LAMP CASING COSTINS APPROX. $2K WITH LABOR. AFTERMARKET $700 PLUS LABOR. THE SERVICE DEPARTMENT AT THREE SEPERATE SHOPS HAVE STATED THIS IS A COMMON PROBLEM WITH THE MB C300.

TAIL LIGHT WIRING FOR 2010 MERCEDES C300 WAS REPLACED UNDER THE RECALL ISSUED IN 2014. TAIL LIGHT WIRING IS CURRENTLY EXPERIENCING BURNING/MELTING DUE TO INSUFFICIENT GROUND WIRE CAPACITY (ISSUE OF ORIGINAL RECALL). MERCEDES DEALERSHIP WILL NOT REPLACE THE PARTS UNDER RECALL PROCEDURES AND IS REQUIRING PAYMENT FOR REPLACEMENT. TAIL LIGHTS CURRENTLY INTERMITTENTLY WORK BUT EXPERIENCE TOTAL FAILURE OF ALL TAIL LIGHTS (INCLUDING BRAKE, TURN INDICATOR, ETC) WHEN NOT WORKING.

I CHECKED AND IT LOOKS LIKE THE PLASTIC AND WIRE IS MELTING ON RTE RIGHT TAIL LIGHT.

TAIL LIGHT ASSEMBLY BURNING UP AGAIN. MY 2010 MB C300 4MATIC SPORT HAD A RECALL TO REPLACE BOTH TAIL LIGHT ASSEMBLIES ABOUT 3 YEARS AGO. NOW IT IS HAPPENING AGAIN AND MB DEALER WANTS $159 JUST FOR A DIAGNOSTIC. PROBLEMS: DASH WARNING MESSAGES STARTED TO APPEAL SAYING PROBLEMS WITH TAIL LIGHT, BRAKE LIGHT, FOG LIGHT, TURN SIGNAL, REVERSE LAMP... EVERYTHING IS OUT. LIGHT BULBS LOOKED FINE BUT I REPLACED ALL BULBS ANYWAY (FROM AUTOZONE PARTS), WORKED FOR A FEW HOURS, THEN WARNING MESSAGES SHOWED UP AGAIN. REPLACED ALL BULBS AGAIN. SAME THING. THEN ONE DAY, MESSAGES STOPPED AND EVERYTHING IS WORKING AGAIN. THEN A FEW DAYS LATER, IT STARTED AGAIN. WENT TO A MB DEALER (AT CHANTILLY, VA) ON 10/2/18 WHO WANTED $159 JUST FOR A DIAGNOSTIC TEST. I INSTEAD PURCHASED A NEW TAIL LIGHT PANEL (LAMP CARRIER P/N 204-820-15-00-05) AT $20 BEFORE TAX TO REPLACE ON MY OWN. CAME HOME OPENED UP THE PANEL AND FOUND A BURNED WIRE. IT EVEN MELTED THE BLACK PLASTIC HOUSING OF WIRE HARDNESS AND A BLACK BURNED MARK ON THE PANEL (CARRIER). PLEASE SEE ATTACHED PHOTOS. THIS CAN CAUSE A CAR FIRE. ALSO VERY UNSAFE DRIVING BECAUSE TUNE AND BRAKE LIGHTS ARE NOT WORKING. SHOULDN'T MB FIX THIS AGAIN AT NO CHARGE? PLEASE RECALL AGAIN.

THERE ARE TWO PROBLEMS THAT HAVE SHOWN UP ALL AT THE SAME TIME JUST RECENTLY. OVER THE LAST SEVERAL WEEKS IT SEEMS THAT EVERYDAY WHEN I GO LEAVE IN MY CAR I AM GETTING A NEW WARNING MESSAGE ABOUT ANOTHER LIGHT I NEED TO CHECK. AT FIRST IT WAS PROMPTING ME TO CHECK THE RIGHT REAR TAIL LIGHT WHICH APPEARS TO BE WORKING FINE. BUT NOW THE LIST HAS GROWN TO INCLUDE THAT TAIL LIGHT, A TURN SIGNAL LIGHT, LICENSE PLATE LIGHT AND A COUPLE MORE EVEN THOUGH TO ME IT APPEARS THAT ALL ARE WORKING FINE WITH THE EXCEPTION OF THE LICENSE PLATE LIGHT WHICH IS TRULY OUT. HOWEVER THE WARNING ARE LISTED FOR ALL THESE MALFUNCTIONING LIGHTS. THE SECOND ISSUE IS WITH THE POWER STEERING. IT STARTED MAKING A DISTRESSING NOISE ONE EVENING ON MY DRIVE HOME, IN WHICH I WAS ABLE TO REACH MY HOME WITHOUT TROUBLE. HOWEVER WHEN I TRIED TO LEAVE THE NEXT MORNING THE POWER STEERING ON THE CAR WAS COMPLETELY NOT WORKING AND I WAS HAVING SUCH A HARD TIME TURNING THE WHEEL BACKING OUT OF MY DRIVE THAT I THOUGHT IT SMART NOT TO TAKE IT OUT ON THE ROAD AND PULLED IT BACK UP INTO MY DRIVEWAY WHERE IT HAS SAT FOR THE LAST SEVERAL DAYS. LUCKILY MY SON IS AWAY AT BOARDING SCHOOL BUT HE DOESN'T NEED HIS CAR THERE SO I HAVE HAD IT AVAILABLE TO GET ME TO WORK AND BACK UNTIL I HAD THE TIME TO LOOK INTO THE ISSUE WITH MY CAR WHICH I AM DOING NOW.

A LITTLE LESS THAN A YEAR AGO MY DRIVER SIDE INNER PARKING LIGHT BULB FAILED, AND ABOUT A WEEK LATER THE PASSENGER SIDE INNER PARKING LIGHT BULB FAILED AS WELL. WHEN I WENT TO REPLACE THEM, THE BULB AND HEADLIGHT ASSEMBLY SHOWED VISIBLE DAMAGE FROM WHERE IT APPEARED AS IF BOTH BULBS CAUGHT ON FIRE AND MELTED INTO THE HEADLIGHT ASSEMBLY, PERMANENTLY DAMAGING BOTH DRIVER AND PASSENGER HEADLIGHT ASSEMBLIES. THERE WAS THE PRESENCE OF CHARRING ON THE BULB SOCKET AS WELL. I TOOK THE VEHICLE TO THE LOCAL MERCEDES BENZ DEALERSHIP AND THEY STATED THERE WAS NOTHING THEY COULD DO EXCEPT TO REPLACE BOTH HEADLIGHT ASSEMBLIES. IF IT WERE MERELY ONE BULB THAT FAILED IN THIS MANNER, I WOULD HAVE CHALKED IT UP TO MAYBE A FAULTY BULB OR SOCKET, BUT IT IS VERY ODD THAT IT OCCURRED ON BOTH INNER PARKING LIGHT ASSEMBLY.

MY CAR IS ALWAYS PARK IN THE BACK OF MY YARD.. AND I ALWAYS CHECK AROUND MY CAR REGARDLESS OF WHERE I AM... DROVE TO WORK WHICH TOOK ABOUT 15 MINUTES AND NOTICE WHEN I GOT IN MY CAR TO GO TO LUNCH THE FOG LIGHT WAS OUT ON THE LEFT DRIVING SIDE AND THE RIGHT FOG LOG IS CRACK ALSO.. NO OTHER VEHICLES PARKS IN FRONT OF ME BECAUSE I PARK FACING THE BUILDING OF MY WORKPLACE. TOOK IT TO THE DEALER SHIP SHE ADVISE THAT SOMEONE BURST THE FOG LIGHT OUT ON THE LEFT DRIVE SIDE AND GAVE ME A QUOTE OF $350 TO FIX FOR EACH FOG LIGHT... ADVISE COULDN'T BE POSSIBLE BECAUSE OF HOW PECULIAR I AM WITH HOW AND WHERE I PARK AND BECAUSE I CHECK MY VEHICLE BEFORE ENTERING TO DRIVE... I USE TO DRIVE WITH MY FOG LIGHTS ON COMMUTING BACK AND FORTH TO WORK. THE ONLY THING I CAN SEE IS THAT IT GOT OVERHEATED BUT HOW BECAUSE OF THE SHORT COMMUTE TIME... TRYING TO UNDERSTAND. *TR

I RECEIVED NOTICE OF A SAFETY RECALL INVOLVING THE REAR TAIL LIGHTS FOR MY 2010 MERCEDES C300. THIS CAR HAD PREVIOUSLY BEEN IN AN ACCIDENT AND DECLARED A TOTAL LOSS. HOWEVER, IT WAS REBUILT, INSPECTED, AND CERTIFIED AS ROAD WORTHY. THE MERCEDES DEALERSHIP REFUSES TO PERFORM THE RECALL WORK ON MY CAR, STATING THAT THE FACT THAT THE CAR WAS A TOTAL LOSS INVALIDATES ANY WARRANTY AND A SAFETY RECALL IS CONSIDERED WARRANTY WORK. I FEEL THAT A SAFETY RECALL IS NOT OPTIONAL, AND THAT MERCEDES NEEDS TO PERFORM THIS WORK, REGARDLESS OF WARRANTY ELIGIBILITY. *TR

SECOND INCIDENT OF ALL LIGHTS SUDDENLY FAILING AND THEN BEING RESTORED WITHIN THREE SECONDS DEALER FIXED BY CHANGING OUT LIGHTING SWITCH BECAUSE THEIR DATABASE SHOWED SIMILAR INCIDENTS WITH OTHER SIMILAR CARS AND CHANGING THE LIGHTING SWITCH APPEARED TO CURE THE PROBLEM ALTHOUGH NO PROBLEM COULD BE SEEN WITH SWITCH. ALTHOUGH ONLY 3 MONTHS OUT IF TIME ON THE ORIGINAL WARRANTY MERCEDES DECLINED TO PAY FOR THE REPAIR AND TOLD ME THAT I SHOULD HAVE CONSIDERED BUYING AN EXTENDED WARRANTY. I REMONSTRATED THAT THIS WAS A POTENTIALLY SERIOUS FAULT AND THAT MERCEDES SHOULD ISSUE A RECALL -MERCEDES DECLINED ANY FURTHER ACTION. *TR

THE WARNING SYSTEM FOR THE REAR LIGHTS HAVE BEEN GOING OFF SINCE PURCHASING THE CERTIFIED PREOWNED VEHICLE IN JUNE 2014. IT WAS RETURNED THE DEALER MULTIPLE TIMES FOR THE ISSUE AND NEVER FIXED. WHILE DRIVING AT NIGHT I SMELLED SOMETHING BURNING AND THE WARNING SYSTEM INFORMED ME TO CHECK ALL OF MY REAR LIGHTS. THERE WERE NO LIGHTS FUNCTIONING ON THE REAR OF THE VEHICLE WHILE DRIVING. THE LIGHTS, BRAKE LIGHTS, TURN SIGNALS, AND REAR FOG LAMPS WERE ALL NOT FUNCTIONING. WHEN A ROAD SIDE TECHNICIAN CHECKED THE VEHICLE HE SAW BURNT WIRES AND MELTED PLASTIC ON THE LIGHTING MOUNT. THIS OCCURRED DURING A ROUTINE TRIP FROM NEW JERSEY INTO PHILADELPHIA, PA AND INCLUDED DRIVING OVER THE BEN FRANKLIN BRIDGE. ONCE I REACH PHILLY I STOPPED THE VEHICLE AND CALLED FOR ASSISTANCE. THAT IS WHEN THE ISSUE WAS LOCATED. THE CAR WAS TOWED TO THE DEALER FOR REPAIR. NO MORE INFORMATION HAS BEEN PROVIDED FROM THE DEALER YET. *TR

RECEIVED MESSAGE REAR LICENSE LIGHT OUT. REPLACED BULB BUT CONTINUED GETTING MESSAGE. REAR PARKING CAMERA STARTED DISPLAYING IMAGES WHEN BRAKE DEPRESSED. MESSAGES CONTINUED TO CHECK ALL REAR LIGHT BULBS. WHEN INSPECTING, I NOTICED BURN MARKS ON BULB CARRIER (PART #211-545-03-28) AND PLUG (PART #204-820-09-77). I PURCHASED NEW PARTS TO INSTALL BUT HAD DIFFICULTY REMOVING THE WIRE CLIPS FROM THE PLUG. I WAS NOT AWARE AND THE MERCEDES PARTS DEPARTMENT DID NOT MENTION I WOULD NEED TO ALSO GET CONNECTOR PINS (OR THAT THIS OVERHEATING WAS A RECURRING PROBLEM). UNABLE TO EASILY REMOVE WIRING & PINS, I DECIDED TO SEARCH INTERNET FOR GUIDANCE ON REPLACEMENT (BEFORE CUTTING WIRES) AND DISCOVERED SEVERAL WEBSITES RECITING OTHERS HAVING SIMILAR PROBLEMS WITH OVERHEATING OF THE GROUND WIRE CONNECTION AND THAT A RECALL INVESTIGATION HAD BEEN STARTED. IT CERTAINLY APPEARS THAT THIS PROBLEM OF OVERHEATING/MELTING OF PARTS IS A REAL FIRE HAZARD THAT IS OCCURRING FREQUENTLY ENOUGH TO AT LEAST REQUIRE THAT A NOTICE BE SENT TO CAR OWNERS TO HAVE CARRIAGES & WIRING PROMPTLY INSPECTED AND REPAIRED. *TR

ALL BULBS ON THE RIGHT SIDE TAIL LIGHT ARE NOT WORKING, THAT INCLUDES BRAKE LIGHT, REVERSE LIGHT, AND SIGNAL LIGHT. I THOUGHT THE BULBS WERE OUT BUT WHEN I WENT TO CHANGE THE BULBS THEY WERE ALL FINE. WHAT I DID NOTICED WAS THE BROWN WIRE WAS BURNT AND SO WAS THE PLASTIC THAT HOLDS THE WIRES TOGETHER, IT SEEMED LIKE THAT ENTIRE SIDE WAS BURNT AND EVEN MELTED. THIS SEEMS TO BE AN ELECTRICAL PROBLEM AND IT ALSO SEEMS TO BE A SAFETY HAZARD. I'VE MENTIONED THIS A FEW TIMES TO THE DEALER. EACH TIME THEY LOOK FOR A RECALL WITH NO SUCCESS. I REPORTED THE PROBLEM DIRECTLY TO MB AND SINCE THERE STILL HASN'T BEEN A RECALL, I'M NOW REPORTING TO NHTSA. *TR

I GOT COUPLE WARNING MESSAGES ON MY 2010 MB C-300 THAT THE TAILLIGHTS WERE NOT WORKING. WHEN I TOOK THE CAR TO THE DEALER'S SERVICE DEPARTMENT THINKING IT WAS THE LIGHTBULBS THAT NEEDED TO BE CHANGED, I FOUND OUT THAT THE TAILLIGHT WIRES AND CONNECTORS HAVE OVERHEATED AND MELTED. IN MY CASE, THE DEALER SERVICE DEPARTMENT AND MERCEDES CUSTOMER CARE DID TAKE THE INITIATIVE AND REPLACED THE WIRES AND CONNECTORS WITH NO COST TO ME, AFTER I DISCUSSED WITH THEM ABOUT THE FACT THAT THIS PROBLEM IS CURRENTLY UNDER INVESTIGATION BY NHTSA. I DO APPRECIATE MB DEALER AND CUSTOMER CARE'S HELP TO RESOLVE THE ISSUE AND TAKE CARE OF MY CAR. HOWEVER, I WANT TO REPORT MY CASE TO NHTSA TO HELP YOUR AGENCY IN DATA COLLECTION TO DETERMINE HOW WIDE SPREAD THE PROBLEM IS AND WHETHER A RECALL SHOULD BE WARRANTED. *TR

I SPOKE TO ONE OF MY MECHANIC FRIENDS WHO SUGGESTED I BRING THE CAR BACK TO THE DEALER TO TRY AND RESOLVE THE PROBLEM AND HE ALSO ADVISED ME TO DISCONNECT THE WIRES OR SOMETHING LIKE THAT AS THIS COULD CAUSE A POTENTIAL FIRE. SINCE I'M PAST THE WARRANTY PERIOD (50,000 MILES) I'M NOT SURE HOW I'M GOING TO FIX THIS PROBLEM, IT MAY BE PRETTY COSTLY AND I'M NOT SURE WHERE TO START.
