Traveling on interstate, vehicle suddenly jerked (as if I hit something on the road) complete electrical failure. Dash, radio, navigation, power steering went dead. A few seconds later power came back while vehicle was still rolling and was able to restart by depressing brake and "start/stop" button. A few minutes later while traveling at lower speed, the event repeated. This time power would not return. Car was in motion and was able to roll to emergency shoulder. Car was stuck in neutral so emergency brake engaged to prevent roll back. Power gone, unable to roll down windows, activate sunroof, radio or anything requiring power. While call was being made to roadside assistance and after 10 minute wait on hold, dash illuminated power and car was able to be started with start/stop button. Decision was made to leave interstate and take back roads to avoid fatality in event of repeat. Failure experience 3 additional times. . Read more...
