What happened? Car won't start, electronics don't work.

Check your battery ground.

sounds like a loose connection/ground.

I just tried again and it worked as normal. It didn't have any issues cranking over and everything worked normally. Battery voltage with the car off was 12.46. The battery is less than 2 years old and it's been in CA (and garage kept) the whole time so no extreme lows. I'm having sorta a hard time believing that it would die so soon.

Or bad connection at a battery terminal. Or a dying alternator and a bad battery.

dead battery

I was driving the car, everything seemed fine. I noticed a few times during my drive that my V1 power cycled itself a few times while I was driving. That's never happened before.

Now like an hour later I go to start the car and it's completely dead. Turn the key and nothing happens, no crank, no dash lights.

Any ideas on what it could be?
