I have a 2012 sport with 94k miles on it. Recently, the car stalled while driving (all electrical went dead; radio, steering, engine, everything) and I had to come to a complete stop, put it in park, then it would start right up. This has happened three times over the last 6 months. I refreshed all the ground cables and battery terminals, but still it just happens every once in awhile. Has put me in danger a few times while in traffic. Thoughts?

If "everything " goes off like you've turned the car off I might look at the BCM or ignition switch?
