2002 Mercedes-Benz C-Class Electrical System Problems

While changing one of the lights in the headlight housing, I found the wiring's insulation rotting off all the wires, exposing the bare copper presenting a fire hazard.

There is an old recall campaign for the Camshaft Seal, # 2009100001. This car is among those affected by this problem and should be covered for issues and repairs.

TL* THE CONTACT OWNS A 2002 MERCEDES-BENZ C240. THE CONTACT STATED THAT THE INSTRUMENT PANEL LIGHTS FAILED TO ILLUMINATE PROPERLY. THE CONTACT STATED THAT THE ODOMETER WAS INOPERABLE. THE VEHICLE WAS TAKEN TO MERCEDES-BENZ OF TACOMA (1701-C ALEXANDER AVE E, FIFE, WA 98424) WHERE IT WAS DIAGNOSED HOWEVER, THE CONTACT WAS STILL AWAITING INFORMATION ON THE CAUSE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE APPROXIMATELY 90,000.*DT*JB*DT THE CONSUMER PROVIDED A PHOTO. *TR

TL* THE CONTACT OWNS A 2002 MERCEDES BENZ C320. THE CONTACT STATED THAT THE BATTERY WAS DRAINED AFTER THE VEHICLE WAS PARKED AND TURNED OFF. THE VEHICLE FAILED TO RESTART. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE DRIVER'S SIDE SEAT MODULE WAS DEFECTIVE WHICH CAUSED THE BATTERY TO DRAIN. THE MODULE WAS UNPLUGGED TO PREVENT THE BATTERY FROM BEING DRAINED. THE MANUFACTURER AND LOCAL DEALER WERE NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 114,000.

Battery drains after being parked overnight, 58,000 miles, dealer maintained since new. Driven by a little old lady until I bought it. Took it to the dealer and they replaced one of the seat modules. Soon afterward, the problem recurred. Took it back to the dealer and they said it was a defective fuse box and replaced it for $650. Went to pick up the car and the battery was dead again. After some complaining, they refunded the bill. They looked at it again and said the problem was somewhere in the dashboard and it would cost $2300 just to take it apart and look for a bad module. They offered $2300 trade in toward a new or CPO car, and said my car would be sent to the crusher. I took the car back and installed a remote operated battery cutoff, and have been driving it ever since. Other than disturbing the engine computer, it's been running well for three years and 20,000 miles. Lovely car otherwise.

TAKATA RECALL ESL (ELECTRIC STEERING LOCK) COMPONENTS THE MOTOR FAILS TO UNLOCK THE STEERING THE FIRST TIME, BUT WORK IN FOLLOWING ATTEMPTS. SOME TIMES IT TAKES 1 TO 4 HOURS FOR ESL TO UNLOCK. THIS HAPPENS ONLY WHEN THE VEHICLE IS PARKED WEATHER OVERNIGHT OR JUST COMING OUT OF THE STORE SHOPPING.

BATTERY DRAINING

TL* THE CONTACT OWNS A 2002 MERCEDES-BENZ C240. WHILE DRIVING VARIOUS SPEEDS, THE INSTRUMENT CLUSTER LIGHTS FAILED TO OPERATE. THE FAILURE RECURRED INTERMITTENTLY. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE INSTRUMENT CLUSTER NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE VIN WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 06V028000 (INTERIOR LIGHTING). THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 120,000. THE VIN WAS NOT PROVIDED.

WAS DRIVING ON HIGHWAY WHEN ESP, BAS AND ABS LIGHTS SHOW UP, AND SPEEDOMETER DISPLAY STOPS WORKING - SPEED READING GOES TO ZERO, THOUGH THERE IS NO REDUCTION IN SPEED. GET TO DESTINATION. ON RETURN IT HAPPENS AGAIN. THIS TIME I GO TO REST AREA, STOP THE CAR, REMOVE THE KEY AND RESTART. THE CAR REFUSES TO MOVE OUT OF PARK. CALL ROADSIDE ASSISTANCE AND GET INSTRUCTION TO OVERRIDE PARK, DRIVE HOME WITH FLASHERS ON - VERY ROUGH RIDE QUALITY. TOW TO DEALER NEXT DAY, THEY ARE NOT SURE IF NEW PART WILL FIX IT, EVEN IF $1850 PART IS REPLACED. LOTS OF ELECTRICAL PROBLEMS OVER THE YEARS. TURN LIGHTS GO OUT ROUTINELY. CHANGED CD CHANGER. SEAT DRAINS BATTERY,HAD TO DISCONNECT IT. POOR ELECTRICAL SENSORS ALL AROUND. NOW IT ALSO HAS RUST DAMAGE, ALL OF A SUDDEN, AT THE BOTTOM OF DOORS.

TL*THE CONTACT OWNS A 2002 MERCEDES C320. THE CONTACT STATED THAT THE VEHICLE WOULD NOT START. THE CONTACT MENTIONED THAT AFTER AN HOUR, THE VEHICLE WAS ABLE TO START. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS 123,384.

SEAT CONTROL MODULE DRAINING THE BATTERY. CAR WILL NOT START IF NOT DRIVEN FOR 24 HOURS. 99% OF THE CARS WITH THE SEAT CONTROL MODULE PART NUMBER STARTING WITH "203" ARE BAD!! WHY WONT MERCEDES RECALL THEM AND REPLACE WITH NEW ONES FREE OF CHARGE. ITS OBVIOUS THAT ITS A DEFECTED PART AND IT WILL CAUSE OTHER THINGS TO GO BAD. WE SPEND ENOUGH HARD EARNED MONEY ON BUYING THE CAR TO HAVE TO PAY FOR THERE DEFECTIVE PARTS. THAT'S WHY THEY ARE CALLED THE STEALER NOT THE DEALER! *TR

I AM NOT SURE WHY MERCEDES IS DOING THIS. I AM SURE THE AUTO MAKER IS AWARE OF THE SITUATION AND NOT DOING ANYTHING ABOUT IT. I HAVE READ NUMEROUS FORUMS REGARDING THE SAME ISSUE. ELECTRICAL COMPONENTS NOT FUNCTIONING PROPERLY. I DEMAND MERCEDES TO DO SOMETHING ABOUT THIS PROBLEM AND THEY CAN NOT GET AWAY CLEAN HANDS JUST LIKE ANY OTHER AUTO MAKERS. THIS ARE PEOPLE LIVES YOU ARE PLAYING WITH AND YOU AS A AUTOMAKER HAVE NO REMORSE FOR PEOPLE LIVES. THIS IS NOT A MOVIE WHERE YOU CAN JUST CALCULATE YOUR COLLATERAL DAMAGE AND GET AWAY. WILL NEVER BUY MERCEDES EVER AGAIN. I AM VERY DISAPPOINTED. ITS ONE ISSUES AFTER ANOTHER. MY CAR JUST STOPS ON HIGHWAY ALL OF SUDDEN LOSES POWER AND HAVE TO TURN IT OFF AND TURN IT ON AGAIN. I HAD ALMOST EVERYTHING REPLACED IN THE CAR, SPARK PLUGS, ALTERNATOR, BATTERY(THAT WENT OUT 3 TIMES). OH DON'T GET ME STARTED ON THE AIR CONDITIONER - THE PARTS ARE MADE SO CHEAP THAT THERE IS A LITTLE HOOK TYPE THING THAT REGULATES THE SPEED OF THE SPEED BREAKS SO EASILY I CANT BELIEVE IT. COUNTLESS FORUM DATA EXIST AND NHTSA DOESN'T DO ANYTHING ABOUT IT. BAN THIS AUTOMAKER OR TELL THEM TO GIVE ME A NEW CAR. NOW I AM LOOKING TO SPEND CLOSE TO ANOTHER $600-$1000 BUCKS TO DIAGNOSE AND REPLACE PARTS. THIS IS NOT A JOKE. OH THEN THERE IS THAT WHEEL BEARING ISSUE I MEAN COME ON MY DAD OWNS A HONDA ACCORD OLDER THAN MINE ALL HE HAS DONE TO THAT CAR SO FAR IS OIL CHANGE AND REGULAR MAINTENANCE. I DEMAND SOME ANSWER AND POSSIBLE COMPENSATION FROM THE AUTO MAKER. *TR

THERE HAVE BEEN TWO WARNING LIGHTS FOR REAR LIGHTS AND AFTER DRIVING FOR 4 HOURS, A WARNING CAME ON FOR ELECTRICAL STABILITY AND MY CAR QUIT WORKING COMPLETELY. THERE WAS A BURNING SMELL AND I HAD TO RESTART IT. I AM VERY CONCERNED ABOUT THIS. *TR

I HAVE A 2002 MERCEDES C320. MY BATTERY IS DEAD AFTER SEATING OVERNIGHT. TOOK THE CAR TO THE AUSTIN MB DEALERSHIP TO DIAGNOSE THE PROBLEM. I WAS TOLD THAT THE POWER SEAT MOTOR IS DRAINING MY BATTERY. BOTH SEATS. COME TO FIND OUT THAT MANY OTHER PEOPLE HAVE EXPERIENCED THE SAME PROBLEM. I CALLED MERCEDES USA AND THEY SAID THAT SINCE THE CAR IS OUT OF WARRANTY, THERE IS NOT MUCH THEY CAN DO. THAT IS BULL!! OBVIOUSLY SINCE SO MANY PEOPLE WITH THIS CAR MODEL HAVE THE SAME PROBLEM, IT HAS TO BE A MANUFACTURER FAULT. I WAS WONDERING HOW MANY PEOPLE NEED TO EXPERIENCE THIS PROBLEM BEFORE MERCEDES WILL ADMIT THAT THEY HAVE A BAD COMPONENT ON THIS MODEL. I FIGURED,IF ENOUGH PEOPLE CALL AND TELL MB THAT THEY HAVE THIS SAME PROBLEM, THEY WILL REALIZE THAT THIS IS A DEFECTIVE PART AND THEY WILL ISSUE A RECALL AND PAY FOR NECESSARY REPAIRS. PLEASE CALL MERCEDES USA AND REPORT THIS PROBLEM. 1-800-FOR-MERCEDES (1-800-367-6372) OR 201-476-6200. *TR

I HAVE A 2002 MERCEDES C-320 CAR THAT THE BATTERY WILL NOT HOLD A CHARGE! I HAD THE MERCEDES DEALER COME TO MY HOME AND PUT IN A NEW BATTERY. AFTER SPENDING $300 AND 2 DAYS LATER THE NEW BATTERY WAS DEAD. I WAS TOLD IT COULD BE THE ALTERNATOR/REGULATOR BY THE MB DEALER AND THE COST WOULD BE $1,200. I TOOK IT TO MY LOCAL MECHANIC, WHO WORKS ON FOR. CARS, AND THEY REPLACED THE ALTERNATOR/REG. FOR $512 OUT THE DOOR. 2 DAYS LATER THE BATTERY WAS DEAD AGAIN. I WAS TOLD MY NEW MERC. BATTERY WAS NOT GOOD AND THEY REPLACED IT. 7 DAYS LATER MY BATTERY DIED AGAIN. MY LOCAL MECH. TOLD ME TO TAKE IT BACK TO THE MB DEALER AS THERE SEEMS TO BE A PROBLEM WITH THEIR MODULE AND THEY SHOULD REPLACE IT FOR FREE AS THROUGH HIS RESEARCH MANY INDIVIDUALS ARE HAVING THE SAME PROBLEM. CLEARLY A DEFECT PART BY MERCEDES AS THROUGH MY AND MY MECH. RESEARCH, THE MB MECH ARE REPLACING THE OLD MODULES WITH A NEW AND IMPROVED ONE TO FIX THE PROBLEM. I NOW HAVE NOW HAD AAA TO COME AND CHARGE MY BATTERY ONCE AGAIN AND I WILL TAKE IT TO THE MB DEALER. I HOPE THEY A WILL DO THE RIGHT THING. *TR
