I was traveling on the highway at 5:30am with minimal traffic. While traveling at 66mph, I put the car into cruise control. Then I pulled my foot off the gas pedal that placed it flat footed with me leg towards the seat. I am a short person. I have 3 house keys on a ring attached to the car key. I felt my knee touch the dangling keys. At that moment, the electrical system and car shut down. I had no power brakes or no power steering, etc. I was in the lane closest to the breakdown lane. I was able get the car into the breakdown lane and cost to a stop. (fortunately no traffic passed me until I finally stopped. ) the ignition key and switch was in the on position when I stopped. I was able to restart the car by placing the car in park and restarting the car. I brought the car to the dealership. They looked at the car and found no error codes. They could not duplicate my problem. They told me I must have shut off the ignition switch with my knee. I attempted to do this an cannot turn the key off with my knee. I addition, my knee does not reach the switch without lifting it up at least a couple inches. I only brushed the bottom of the dangling house keys. 2010 should be included in the recall!!!.
