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

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

Electrical system, Apr 29, 2009
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

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
Electrical system, Seats, Dec 19, 2008
SEAT CONTROLLER MODULES, THEY CONSTANTLY DRAIN THE BATTERY WHEN THE CAR IS OFF. THIS IS A VERY VERY COMMON PROBLEM WITH MERCEDES C CLASS. THE CONTROLLER DRAINS THE CAR BATTERY TO THE POINT WERE THE CAR CANNOT START, AND CONTINUES TO DO THIS IF THE CAR IS NOT DRIVEN EVERYDAY. OBVIOUSLY HAVING A CAR BATTERY GET SUCKED BELOW 3V IS NOT HEALTHY FOR THE BATTERY, AND IN THE END EVERYONE WITH THIS PROBLEM HAS TO REPLACE THEIR BATTERY MANY MANY TIMES. *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

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

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

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

I HAVE A 2002 MERCEDES C320 AND THE CAR'S BATTERY KEEP DYING AND I HAVE TO JUMP START MY CAR EVERY DAY. BATTERY WAS REPLACED AND SAME PROBLEM HAPPENS AGAIN AND AGAIN. I WENT ONLINE AND FOUND OUT THAT I AM NOT THE ONLY PERSON WHO HAS THE PROBLEM. IT HAPPENS TO MANY MANY MANY PEOPLE - SEE ATTACHED LINK HTTP://WWW.BENZWORLD.ORG/FORUMS/W203-C-CLASS/1196568-MERCEDES-C320-BATTERY-DRAIN-4.HTML I HAVE PAID THE DEALER $375 JUST FOR THE DIAGNOSES WITH NOTHING FIXED AND ACCORDING TO THESE COMPLAINTS, EVEN AFTER THEY HAVE THE RECOMMENDED REPLACEMENT, THE PROBLEM PERSISTS. IT SEEMS LIKE THEY SHOULD HAVE ALL THESE CARS RECALLED AND HAVE THE PROBLEM FIXED WHEN IT'S THEIR PRODUCTION/COMPONENT PROBLEM.

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.

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
