Hello - The 12v battery in my 2020 Kona EV has fully drained twice in the last 6 weeks. The first time the back hatch was ajar for about 4 hours. The second time not sure what was active, but again drained after about 4 hours. I've never had any similar issues since purchase and now at 39,000 miles. Have other owners had to replace their 12v batteries and at what number of months or miles? I've got an appointment at the dealer next week. BTW: I found this post very helpful for tips on how to jump the battery safely and then reset anything required: https://evjuicedup.com/can-i-jump-start-a-kona-electric/ Thanks!
The search function is a useful tool, particularly concerned 12V battery. This link will take you to the already existing 4+ threads where I think you will find any questions answered...
DOH! Yep - very thorough. Seems like I'm due for replacement and may want to get a BM2 battery monitor. Thanks!
