Several tries at power button failed. Icon on dashboard (small car image) flashing whether nor not I was in the car. Lights worked and emergency flashers worked. After many tries, called AAA. The AAA driver got in the car and it started right up and has worked ever since. Called dealer. Never heard of such a thing. Does anybody know what happened.
Likely possibilities: 12V battery dying; brake position sensor bad; operator error. The flashing icon is normal, indicating that the immobilizer system is working. It's always been there.
