On the evening of 12/18/15 (10:00pm), after starting up the car, none of the controls located on the steering wheel and steering wheel column would operate. I had no turn signals and no wipers and no cruise control. A minor inconvenience was that I could not operate any systems nor the radio from the steering wheel. After turning off the vehicle at home the car acted as though the key was still in the ignition even though it had been removed and the headlights would not turn off. I had to disconnect the battery to kill the headlights. When I reconnected the battery the following morning all systems were working again.
