Got in the car after being parked for about 48 hours at work. Start her up and NONE of the electrical functions controlled from the steering column worked. No cruise control, turn signals, wipers, horn, audio and phone controls. This is the second time it has happened in about 6 months. Both times everything came back after parking at home in the garage overnight. I've asked 2 techs about it and they claim to have never heard about the issue. And, of course, being intermittent it's almost impossible to trace. Any thoughts are appreciated.
