Yeah, only plugging in the car, not putting a charger on the 12v, although i could do that. So, if i didn't charge the 12v at home, I got enough charge to get rid of the stop safety now triangle and the check engine light just from driving home for 20 minutes. I'm going to take it out today in EV later mode only and see if that charges the battery up well enough. It's been plugged in over night, so the charge is full on the hvb. So after that, it should have been charging the 12v battery for the rest of the night. I didn't know it worked like that. Thanks! Makes me feel better about driving 30 minutes from home today, haha. I might buy a replacement battery and just keep it in the trunk. I don't want to be a out in the middle of nowhere and have this happen again. Thank you for the reply!

Had the car plugged in for another hour or so, went outside and turned it on , the check engine light was off, and i drove it around the block with no issues. Thoughts? Maybe the battery is old and drained quickly? All looks to be fine now. Should is still look into a replacement 12v battery?

So, i went camping and accidentally left my car in acc while unpacking and setting up. I turned it off and later the car trunk wouldn't open with the remote. I turned the car on and popped the trunk. When i turned off the car, instead of staying on for a bit like usual, a note popped up that said turning system off for battery saving mode or something like that. In the morning, i had to turn it on to get the rest doors unlocked and the trunk open. Then it turned itself to battery saving mode and the bar was really close to the bottom. When it was time to leave, it wouldn't start. So, i got the transer to jump it. Car starts, check engine light goes on and stop safety now triangle. I drove home carefully. Took about 20 minutes and the car drove fine. Got home and read the code: P0562 low system voltage Plugged the car in to charge. It charged for about an hour, which isn't much. I charge at a low rate. Went back out, unplugged the car, left it off, and checked the battery in the trunk. It read 12.59. Turned the car on and it read 14.81. The stop safety now light went off, but the check engine light is still on. I know sometimes it takes a while for that light to go off. Any thoughts on the situation? Where to go next?
