Lose Power Steering problems of the 2011 Honda FIT

Lost power steering while driving on the hwy in my 2011 Honda Fit with about 58,500 miles driven. . Had car parked in the sun for several hours with ambient temperature of 92f, got in and drove home, had radio on, a/c on, gas level close to the empty indicator ("e"). , and within 5 minutes of driving, was on the freeway at that time, the electric power assisted steering functionality failed. I almost lost control of vehicle, steering was heavy and difficult, no lights illuminated to indicate a problem, was able to stay in # 1 lane till I reached home. When I started the car the following day, and power assist functionality was magically restored. I visited the local Honda dealership service department and service representative claimed that he has not heard of such problems with the Honda Fit, even for earlier years when I asked specifically. Service representative was not even interested in hooking up any devices to see if information can be retrieved from the computer in the car.
