Driver's side seat back, left bolster, started to smoke and burned a dime size hole in the leather seat cover. Driver's seat heat was on at the time. Turning the seat heat off seems to have solved the problem temporarily. Suspect short in seat heat wiring. Potential fire hazard!

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 stated the automatic driver seat in the vehicle moved forward on its own, pushing the contact into the steering wheel. The vehicle was not recording the correct seat position of each driver. The vehicle was taken to a service dealer who was unable to duplicate the problem. Also, both front tires made a thumping noise while driving at any speed. A service dealer determined that the wear on the tread was uneven. Due to the vehicle having staggered wheels, the tires could not be rotated.
