WE OWN A 2001 MERCEDES C320 AND HAVE HAD SEVERAL PROBLEMS WITH THE ELECTRICAL SYSTEMS ALL RELATED TO THE POWER SEAT ASSEMBLIES DRAINING THE BATTERY OVER NIGHT. WE HAVE HAD THEM REPLACED BY THE DEALER, FIRST TIME WAS UNDER WARRANTY, AND NOW- JUST ABOUT A YEAR OR SO LATER, SAME PROBLEM. IF WE UNPLUG THE POWER SEATS, THE BATTER DOES NOT DRAIN. WE KNOW WE ARE NOT THE ONLY ONES WITH THIS PROBLEM, SEE WWW.BENZWORLD.ORG/FORUMS/MB-SAFETY-TESTIMONIALS/1279095-C320-BATTERY-PROBLEM-PLZ-HELP.HTML . I AGREE THAT IT IS RIDICULOUS TO SPEND THE TYPE OF MONEY ON THIS CAR AND GET RIPPED OFF BY THE DEALERS FOR "DIAGNOSTICS" ON A VERY WELL KNOWN PROBLEM AND ALSO GETTING SHAFTED FOR REPLACEMENT PARTS, ONLY TO HAVE THEM FAIL THE SAME EXACT WAY. THIS IS A WIDESPREAD PROBLEM FOR MERCEDES, AND TO NOT ACKNOWLEDGE IT AND JUST KEEP RAPING CUSTOMERS WITHOUT FIXING THE ORIGINAL PROBLEM IS WRONG. I CAN ONLY HOPE THIS COMPLAINT WILL KEEP JUST ONE PERSON FROM PURCHASING A MERCEDES, OF ANY TYPE, IN THE FUTURE. MERCEDES NEEDS TO STEP UP AND DEAL WITH THIS. GREAT FOR THE IMAGE TO SEE MB OWNERS GETTING THEIR OVERPRICED CARS JUMP STARTED BY HONDAS AND VOLKSWAGENS...*TR
