12V Battery Keeps Draining

[Alien_Ethereals]

I've been seeing 12V battery drain complaints on the Kia Niro PHEV, and unfortunately, my 2020 model just started doing the same thing.

- New battery installed drained within 36 hours.
- 2.5A current draw when everything is off.
- Dealer appointment is weeks away, so I’m trying to figure this out myself.

Has anyone successfully diagnosed and fixed this issue? Any known culprits that cause parasitic drain on the Niro PHEV?

Parasitic drains can come from telematics, door modules, or faulty relays. Have you tried pulling fuses one by one to isolate the issue?
