2002 Mercedes-Benz C-Class Electrical System

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.

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

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

2002 MERCEDES BENZ C320 STATION WAGON: FAILURE TO KEEP A CHARGE IN THE BATTERY, AND APPARENTLY THE SOLUTION IS TO DISCONNECT THE POWER SEATS AND THEN RECHARGE THE BATTERY. BUT THEN THE POWER SEATS ARE INOPERABLE, UNLESS YOU GET THESE REPLACED. APPARENTLY, THIS IS A COMMON PROBLEM. *TR

CAR STALLED IN THE MIDDLE OF THE ROAD AND ALMOST CAUSED AN ACCIDENT. AFTER 15 MINUTES, CAR STARTED BACK. I HAD IT DIAGNOSED AND A MODULE WAS REPLACED. 2 MONTHS LATER, THE BATTERY STARTED DRAINING. I HAD THE ALTERNATOR REPLACED AND THE BATTERY TWICE. CAR WILL WORK FOR A DAY OR TWO AND DIES AGAIN. SO MANY OTHER MERCEDES OWNERS OF C320 ARE HAVING THE SAME PROBLEM. BATTERY DYING AND CAR STALLING. *TR

BATTERY DRAINING, OFFICIAL DEALERSHIP IS UNABLE TO IDENTIFY WHAT IS CAUSING DRAIN. *TR

BATTERY GOES DEAD AFTER A FEW DAYS: MAJOR CAUSE IS ELECTRICAL POWER DRAIN DUE TO FAULTY UNITS, MAJOR CAUSE BUT NOT ONLY CAUSE IS THE SEAT CONTROL MODULE UNIT. QUICK FIX IS TO DISCONNECT TO ELIMINATE POWER DRAIN BUT THIS CAUSES OTHER SAFETY FEATURES TO GO DORMANT. I HAVE READ MORE THAN 100 REPORTS ON BENZWORLD.ORG ON THE VERY SAME ISSUE WITH LITTLE OR NO SOLUTION FROM DEALERSHIPS. ITS A MAJOR AND COMMON PROBLEM AND SHOULD BE RECALLED BEFORE PEOPLE GET HURT. *TR

WHILE DRIVING ON HIGHWAY OUT OF STATE AT APPROX. 60MPH CAR SUDDENLY BUCKED AND ALL POWER CUT OUT, ALL LIGHTS ON CONTROL PANEL LIT UP- HIT CLUTCH AND GAS, VEHICLE RESTARTED. NEAREST DEALER WOULD NOT SEE ME FOR 2 WEEKS, DEALER IN ANOTHER STATE DID DIAGNOSTIC ESTIMATED REPAIR AT CLOSE TO $4,000; ALREADY GAVE OVER $1800 AS DOWNPAYMENT TOWARD PARTS. REPAIR ? SCHEDULED FOR NEXT WEEK. READ OTHER COMPLAINTS, BELIEVE MANUFACTURER SHOULD TAKE SOME RESPONSIBILITY HERE, AND WANT REASSURANCE IF REPAIR DOES NOT WORK I WILL NOT BE CONTINUOUSLY CHARGED WHILE THEY REPLACE EVERYTHING UNTIL THE GET IT RIGHT. SAID COMPUTER DID NOT READ A DEFECT. CAR HAS BEEN SERVICED BY DEALERS ONLY AT EVERY RECOMMENDED SERVICE MILESTONE. *TR

THE BATTERY IN MY 2002 MERCEDES BENZ C320 DIED IN LATE FEBRUARY 2008. DIAGNOSTICS WERE DONE AND THE BATTERY WAS REPLACED BY BY CHANDLER MERCEDES BENZ VIA ROADSIDE SERVICE. IN LATE MARCH I GOT INTO THE CAR TO GO TO WORK AND THE BATTERY WAS DEAD; CALLED ROADSIDE SERVICE. CHANDLER MB ARRIVED AND JUMP-STARTED THE CAR. MAY 5TH I GOT IN MY CAR TO GO TO WORK AND AGAIN, THE BATTERY WAS DEAD. CHANDLER MB ROADSIDE SERVICE AGAIN JUMP-STARTED THE CAR WHICH WAS THEN DELIVERED TO THEIR SERVICE DEPARTMENT. THE BATTERY WAS CHECKED AND THERE WAS NOTHING WRONG WITH IT. FURTHER DIAGNOSTICS REVEALED THAT THE DRIVER'S SIDE POWER SEAT MODULE WAS DRAINING THE BATTERY. I REQUESTED A BATTERY THAT COULD POWER THE CAR. WAS TOLD THERE IS NO BATTERY THAT WILL POWER THE CAR, THE POWER SEAT MODULE MUST BE REPLACED TO THE TUNE OF $398.00 PLUS LABOR. I DID FURTHER RESEARCH AND DISCOVERED THAT THIS IS A VERY WIDESPREAD PROBLEM IN THE MERCEDES C320, IN FACT MERCEDES BENZ IS NOW INSTALLING A DIFFERENT MODULE IN THE 2002 C320'S DUE TO THE EXTENT OF THE PROBLEM. IT SEEMS TO ME THAT WHEN I BUY A MERCEDES BENZ WITH A MERCEDES BENZ BATTERY AND A MERCEDES BENZ INSTALLED POWER SEAT MODULE, THERE SHOULD BE SUFFICIENT POWER TO DRIVE MY CAR. ASKING ME TO PAY OVER $400 TO REPLACE THEIR OWN PART BECAUSE IT DRAWS TOO MUCH POWER FROM THEIR OWN BATTERY AND THEN NOT MANUFACTURING A BATTERY THAT WILL PROVIDE THE REQUIRED POWER, IS VERY CONVENIENT FOR MERCEDES BENZ AND A GREAT WAY TO MAKE SOME VERY EASY MONEY, BUT WHEN I PAY $35,000 IN CONSIDERATION FOR A CAR AND THEY PROVIDE ME A CAR THAT DOES NOT HAVE ENOUGH POWER TO RUN, I BELIEVE THERE IS SOME FRAUD GOING ON AND FROM MY RESEARCH IT APPEARS THAT IT IS ON A VERY WIDESPREAD BASIS. JUST THE FACT THAT MERCEDES HAS ACKNOWLEDGED THE PROBLEM BY SWITCHING TO A DIFFERENT MODULE, INDICATES THEY ARE AWARE THAT THEIR ORIGINAL PART IS DEFECTIVE AND I BELIEVE IT'S THEIR RESPONSIBILITY TO BEAR THE COST TO REPLACE IT WITH THEIR REPLACEMENT MODULE. *TR

2002 MERCEDES C320 BATTERY DIES EVERY 2-3 DAYS. NEEDS JUMP START EVERY 2-3 DAYS. *TR

ON MY MERCEDES BENZ C320, IF THE CAR IS NOT STARTED AT LEAST EVERY 12 HOURS, THE CAR WILL NOT START AND IT NEEDS A JUMP. THE CAR IS A 2002 AND HAS 51K MILES. *TR

THE LIGHTS ON MY DASH BOARD FLICKER AND DIM , MAKING IT DIFFICULT TO SEE THE SPEEDOMETER AND OTHER INSTRUMENTS. *TR

MY WIFE DROVE THE CAR IN THE MORNING, NO PROBLEM. EARLY AFTERNOON, SHE LEFT TO PICK UP OUR CHILD, WHILE LEAVING THE NEIGHBORHOOD. THE VEHICLE STARTING SENDING WARNING SIGNS CAME ON THE DASH THAT HAD NEVER BEEN SEEN BEFORE. THEN THICK SMOKE CAME OUT FROM UNDER THE STEERING WHEEL. MY WIFE HAD TO OPEN HER WINDOW. SHE THEN TURNED AROUND TO GO BACK HOME PRIOR TO LEAVING THE COMMUNITY. ON THE WAY BACK THE CAR SLAMMED ON BRAKES BY ITSELF AND CUT ITSELF OFF AND SAID THE VEHICLE HAD 7 FAULTS. RAN UP TO A NEIGHBORS HOME, UPON RETURNING THE VEHICLE WAS ENGULFED IN FLAMES AND BECAME A TOTAL LOSS. POLICE AND FIRE MARSHAL CAME TO INSPECT THE VEHICLE. SINCE THEN, WE HAVE HAD TO TRACK DOWN MERECEDES BENZ AND BASICALLY HAVE HAD NO CUSTOMER SUPPORT WHATSOEVER. WE LOCATED THE VEHICLE FOR MERCEDES AS THEY TOOK THEIR SWEET TIME. THEY DID GET AN INSPECTOR THERE TO VIEW THE VEHICLE BUT HAVE YET TO HEAR ANYTHING FROM THEM REGARDING THIS MATTER. WE HAVE CONTACTED AN ATTORNEY TO PROTECT US AND WANT MERCEDES TO BE HELD LIABLE FOR THIS INCIDENT. SOMETHING WAS VERY WRONG AND WE ARE GRATEFUL THAT NO ONE WAS HURT. *TR

ON FEBRUARY 6, 2007, I TOOK MY MB TO SOVEREIGN MOTOR CARS LTD IN BROOKLYN, BECAUSE OF THE SRS LIGHT. THE ALTERNATOR WAS REPLACED IN 2005 AND THE ABOVE COMPANY TOLD ME THAT IT HAD TO BE REPLACED AGAIN. IN THE MIST OF REPLACING THE ALTERNATOR VIA DRILLING, THE CAP (BOTTOM PART THAT HOLDS THE BOLT) BROKE. I WAS INFORMED THAT THIS IS COMMON BECAUSE OF THE MIXTURE OF ALUMINUM ENGINE AND STEEL CASING. I WAS TOLD MORE THAN 2% OF MERCEDES BENZ VEHICLE THAT ENTER THIS SHOP THE CAP BREAKS AS A RESULT OF OXIDATION AS TOLD BY MR. YELTKIN, SHOP STEWART. SOVEREIGN WANTED ME TO PAY FOR THE REPAIR OF THIS INCIDENT MORE THAN $2000 FOR A FAULTY CAPPING. OR $800 TO HAVE IT WELDED TOGETHER BUT THEN WAS TOLD IT MAY BREAK AGAIN. BOTH BOLTS WERE DAMAGED BUT SOVEREIGN REPLACED THEM WITH TEMPORARY BOLTS TO SHOO ME ON MY WAY. *NM

MY 2002 MERCEDES C230 KOMPRESSOR KEEPS DRAINING THE BATTERY. I HAVE HAD THE BATTERY AND THE ALTERNATOR REPLACED. NO ONE, INCLUDING THE DEALER CAN DETERMINE WHAT IS CAUSING THE DRAIN. ONLINE FORUMS FROM MERCEDES OUTLINE THAT THIS IS A REGULAR ISSUE THAT MERCEDES IS AWARE OF, BUT NO RECALL HAS BEEN ISSUED. *JB
