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 CAR PARKED IN THE GARAGE OVERNIGHT AND THE MORNING I HAD AN EMERGENCY AT THE BUSINESS AND COULD NOT START THE CAR. THE BATTERY WAS TOTALLY DRAINED. HAD IT TOWED TO THE SHOP TO BE DIAGNOSED THAT IT WAS THE FRONT DRIVER SIDE POWER SEAT THAT HAS DRAINED ALL THE ENERGY FROM THE BATTERY EVEN WHEN THE CAR IS NOT RUNNING. THE POWER SEAT IS NOW CONTINUOUSLY EXCESSIVELY DRAIN THE BATTERY EVEN WHEN THE CAR IS NOT RUNNING. THE CONSEQUENCES ARE THAT THE CAR IS NOT TRUSTED TO BE ABLE TO START IN AN EMERGENCY SITUATION WHEN THE CAR IS NEEDED FOR TRANSPORTATION. THE CAR HAS VERY LOW MILEAGE ON IT. THE POWER SEAT HAS BEEN RARELY USED AND IT SHOULD NOT FAIL FOR HAVING BEEN IDLE/NOT USED FOR THE LENGTH OF TIME THAT I HAVE OWN THE CAR. I AM THE ORIGINAL FIRST TIME OWNER OF THE CAR AND I HARDLY HAVE TO ADJUST THE POWER SEAT. I BELIEVE THAT THE POWER SEAT IS A MANUFACTURE DEFECT AND COULD BE A DANGEROUS IMPEDIMENT IN AN EMERGENCY SITUATION. THE ARE LOTS OF MERCEDES OWNER WHO HAVE EXPERIENCING THE SAME MALFUNCTION IN THEIR POWER SEATS. I FEEL THAT WITH THESE MANY PEOPLE, IT WARRANTS A RECALL BY MERCEDES FOR ALL THE POWER SEATS. *TR

I OWN A 2002 MERCEDES BENZ C230, WHICH HAS NOW HAD 2 SEVERE ISSUES WITH IT. THE FIRST ISSUE IS THE ELECTRICAL SYSTEM - THE SEAT CONTROL MODULES GO FAULTY AND START DRAINING THE BATTERY EVEN WHEN THE CAR IS TURNED OFF. IF YOU HAVE A BATTERY DRAIN, THIS IS THE LIKELY CULPRIT. I HAVE REPLACED THE SEAT CONTROL MODULES A TOTAL OF 3 TIMES. THIS IS A COMMON PROBLEM ACCORDING TO INTERNET BOARDS. THE 2ND PROBLEM IS THAT OIL STARTED TO LEAK ALL OVER THE WIRES. AGAIN ANOTHER COMMON PROBLEM ACCORDING TO THE INTERNET BOARDS. *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 VEHICLE WOULD NOT START, SO I RECEIVED A JUMP, TWO DAYS LATER WHEN I DID NOT DRIVE THE CAR IT WOULD NOT START RECEIVED ANOTHER JUMP AND REPLACED THE BATTERY. DID NOT DRIVE THE CAR FROM 7-4 TO 7-8-07 AND CAR WOULD START. WENT TO MERCEDES DEALERSHIP ON 7-9-07 AND WAS TOLD THAT IT WAS A COMMON PROBLEM ON MY CAR THAT THE SEAT MODULES DO NOT POWER DOWN WHEN THE CAR IS OFF AND THAT IT IS DRAINING THE BATTERY. WENT TO SEVERAL MERCEDES-BENZ FORUM WEBSITES AND FOUND THAT THERE WERE HUNDREDS OF PEOPLE HAVING THE SAME PROBLEM. ONCE THE SEAT MODULE ARE REPLACED FOR $1200.00 THAT THE SEAT MODULES WOULD CONTINUE TO DRAIN THE BATTERY AND WOULD HAVE TO BE REPLACED AGAIN AND THIS BECAME A CYCLE. PLEASE VISIT WEBSITES WWW.BENZWORLD.ORG/FORUMS OR M-BENZFORUM.COM OR TYPE IN GOOGLE OR YAHOO MERCERDES BENZ FORUM AND CONNECT. HERE YOU WILL SEE A LIST OF PEOPLE WITH THE SAME PROBLEM. *AK
