What owners wrote

Electrical failure indicator lit up. I was on my way to the dealership service center. Within 10 minutes of driving, the car completely shutdown right at a busy intersection and before an active railroad crossing. Tow truck was called by the police as the car was not starting and therefore undriveable.
