Sometimes when I shut the car off, it goes completely down. If you have a Genesis, you know when you power off you get that nice sound the lights stay on for a while that's a soft shut down in my case. Sometimes when I turn off the power, it's just like somebody pull the plug. And then the car won't restart. Completely black, engine won't turn over, on some occasions, I can disconnect the negative battery terminal and reconnect it and everything lights up like a Christmas tree, sometimes it doesn't and I have to get a jumpstart. Just had the battery replaced last year. I've taken it to the standard AutoZone to check battery and alternator. It always comes back as past.

Very frustrating…
