Seats problem

While driving my 2001 mercedes c240 at freeway speed. The automatic "easy exit" feature shorted out causing my seat to automatically move all the way backwards so that I could no longer reach my clutch, brake or gas pedal. In addition to this my steering wheel moved itself upwards as far as it could go. I nearly wrecked my car when this happened, however I was able to reach my brake pedal by scooting way forward in the seat, and I also was able to push the stickshift into neutral, and pull to the shoulder. I had been having a problem with the drivers side window freezing up, but I had no idea that the relay switch connecting to the electric window, could also cause a short, and thus initiate this most dangerous "easy exit" feature. I had been having problems with all of the door mounted controls, off an on. I had even complain to the dealers shop. But it always seemed that they could not reproduce my complaints, so they told me that it was not broken. This time I took my car in as soon as I could after the seat and steering wheel incident (they could not get my car in until Tuesday, the following week. ) the diagnosis that part #203-820-15-85 (control unit) was faulty. The part was replaced for $579. 20. I feel strongly that Mercedes Benz company should warn any other owners of a car with this part to have it checked. This could have been a serious wreck if I had been in heavier traffic, or was driving in bad weather conditions, such as snow. Thank you in advance for your attention to this matter.
