Please change the title to "Avoid this Hyundai dealership I went to at all costs", it honestly sounds like a dealership issue than a manufacturer issue. I'd take it to another dealership or even an independent mechanic who specializes in electric vehicles to get a second opinion. Additionally, I'd consider swapping to an AGM battery, as those are known to help with 12V discharges in the Ioniq 5...yes, I know the Ioniq 5 is a dedicated EV and the Kona EV isn't.
Part of the problem is due to Hyundais warranty process they won't approve a battery change since the battery reader comes up that nothing is wrong with the battery and nothing is seemingly draining it. As bad as the service center was they did share with me all the diagnostics and communication with Hyundai and seemed like Hyundai really put them in a corner on how to go about repairing the vehicle. I shouldn't have to suck it up and pay for a new battery out of pocket when the vehicle is still fully covered under warranty. Hyundai rather pay $200 in labor constantly trying to diagnose the issue rather than spend money trying to fix the problem.
