The power seat modules continuously drain the battery causing dead battery within 24-48 hours. The seats must be unplugged to stop the problem. Mercedes dealership wants $100 to diagnose and $1,500 per seat module. There are hundreds of people online with the same problem making this a defect.

Defective seat controller modules ( driver and passenger ) cause the battery to drain completely within 24 hours. This leaves me stranded and unable to drive my vehicle. A search online reveals multiple other with the same issues...indicating an obvious safety issue that is well known to the manufacturer with no resolution to this problem from the manufacturer other than paying $1000 for a known defective issue/part.

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.

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.
