   We had a previous issue with our 12V battery not charging, which totally bricked the whole car. Hyundai updated the charge management system software under the active recalls and tested the 12V battery, which after it was fully charged they said was fine. Now (a few months outside our warranty period for the 12v battery), our car was bricked again and was so dead that we could not even start it/charge the battery with a jump start kit. We were stranded on the side of the…
