2002 Mercedes Benz C320

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

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

I OWN A MERCEDES BENZ C320 AND LATELY I'VE BEEN EXPERIENCING SOME PROBLEMS, FEW WEEKS AGO, MY CAR WOULDN'T START ALL OF A SUDDEN. I JUMP STARTED AND I NOTICED 2 FAULTS .. ESP WARNING LIGHT AND LIGHT SENSOR ,FOR SOME REASONS SOMETHING WAS DRAINING MY BATTERY, I WENT AND PURCHASED A BRAND NEW BATTERY AND 2 DAYS LATER IT DID THE SAME THING AGAIN, I WAS TOLD THAT IT WAS A SEAT SENSOR THAT CAUSED IT,S O WE UNPLUGGED THE SEATS, EVERYTING SEAMED FINE FOR LIKE 4 TO 5 DAYS,WHILE I WAS DRIVING,THE CAR JUST CAME TO A COMPLETE STOP WOULD NOT MOVE,THE ENGINE LIGHT CAME ON, I'VE COME TO REALIZE THAT I'M NOT THE ONLY ONE WITH THIS PROBLEM, I HOPE THE GOVERNMENT WOULD DO THE RIGHT THING BY RECALLING THOSE VEHICLES. *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.
