A parasitic draw on a Kia Soul III is usually a module that won’t sleep, a stuck latch or light, or an aftermarket accessory.
Start with the battery and charging system, then measure current draw and isolate fuses.
If your Kia Soul III is dead every morning, you're not imagining it—something is staying awake and sipping current after you lock up. That's a parasitic draw. Before blaming a mystery module, I always confirm the battery itself is healthy and the charging system is working, because a weak battery can mimic a draw and make every small drain look worse. Clean, tight terminals and a proper load test come first.
