Charge curves lie if you don't match starting SOC and temp. Match starting SOC and battery temp if you're comparing 2023 Hyundai Ioniq 5 charge sessions. That's where I'd start. Take it or leave it — that's what I'd do. Happens in gear, not in park, for what that's worth.

I'd treat 12V warnings as a no-ignore. On the 2023 Hyundai Ioniq 5, I'd get the 12V/DC-DC side checked even if the traction pack looks fine. Then you'll know the next fork. On “buzzing noise only at one engine rpm,” that was the fork that mattered for me. Happy to compare notes if your setup is different. If your situation is the opposite, ignore me.
