Seat control module failure. 2 modules per car, 1 for passenger seat, and 1 for driver seat fail. The defective seat control module unit will deplete the cars battery overnight resulting in a no-start condition the following day. A new battery, or a jump start, will get the car going again. The common immediate resolution is to unplug the seat control module which would impact the seats ability to respond in an accident. The replacement part and diagnosis from mb dealer is approx $700/ module. This is a huge liability for Mercedes owners and the repair should be investigated for seat function safety. I understand the part number has been updated, which I believe is an admission by Mercedes that the original part is defective.

The contact owns a 2005 Mercedes Clk320. The contact stated that the vehicle would not start. Once the vehicle was jump started all of the service lights and sensors on the instrument panel would turn on and off. The automatic seat belts would also engage and disengage on their own. The vehicle was shut off but the failures continued to occur. The vehicle was taken to an authorized dealer where they were unable to diagnose the failure; however, they suspect that it could be the electrical system. The vehicle was not repaired. The failure and current mileages were 62,000.
