Car battery drains due to a short in the power seat control units in my 2002 Mercedes Benz C320. Replaced battery, recharged battery numerous times. Every other owner of this make / model complains of same problem.

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.

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.

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.

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 that the seat modules would continue to drain the battery and would have to be replaced again and this became a cycle.
