NHTSA Complaint #11580665 — 2020 HYUNDAI KONA ELECTRIC

We just had our 2020 Kona updated from the dealer with major software and recall updates. Since that point the car has been draining from the 12volt battery on it's own and killing the charging circuit for the battery. It has caused us to have to jump start the car and not be able to keep the 12 volt charged which runs all of the environmentals and car systems. Unless you have a jump pack with you, you have to jump it after every stop. I have tested the battery and it is fine but the system needs a high end initial draw and is not getting it. I have contacted the dealer but they are saying it is not their problem. This needs government address, as it is the same issue in the NHTSA recalls or Hybrid and EV Sonata and Ioniq 5 models.
