NHTSA Complaint #11534291 — 2022 KIA EV6

12-volt battery is not being properly charged while driving. once resulting in loss of power while moving (thankfully still in our driveway) requiring a jump start, and twice when parked which forced us to have to break into (airbag the door) the vehicle to get the trunk open and jump start. It seems to lose 12-volt battery charge if not driving for a few days requiring us to leave it unlocked if we are not using it over the weekend for example. There have been no warning indicators or other warning prior to this occurring. I was in an accident in February and my vehicle was in the shop for a month. I lost contact via my app twice so I assumed the 12v battery died while they had my car, but they didn't mention the issue upon returning the car to me.
