Without any warning, my car would not start last night. The only dashboard light was the red security blinking light. No other dash lights. No codes. At first, there was no response to my pushing the start button. Then the red light on the start button would engage, but no dash lights. In a fast read of possible alternative ways to start, I was finally able to start the car in this manner: Without my foot on the brake pedal, depress the start button for 45 seconds. Release the start button. Press the brake pedal and depress the start button. This started the car. All of the usual dash lights came on at this time. No codes appeared. No warning icons appeared. I drove the car to a destination about five miles away, parked the car, and left it for about 2 hours. When I returned, there was the same issue. I started the car the same way as I described above. When I returned home, I visited the car three times in approx. one-hour intervals, and the car started immediately each time, as it normally did. This morning, the car has started immediately, as it normally has. I have checked it several times this morning, at one-hour intervals, and .... all appears normal. I have searched for similar scenarios on this forum and elsewhere; I've looked in my Prius manual, all to no avail. My key fobs do work, but in the last couple of months, there have been times when the car did not respond when I depressed the unlock button to open all of the doors. On the off chance this has anything to do with it, it happens that a strong wind storm, preceding a heavy rain, rose up minutes before I discovered the car wouldn't start. I realize that sounds bizarre, but I've seen stranger things that have affected technology in surprising ways. Thanks in advance for your ideas.
