This is genuinely worth knowing if your battery keeps going flat after short trips involving fog lights: a documented, real quirk in some Kia wiring means that if you use the front fog light and don't switch it off before turning the ignition off, the light itself goes dark, but the switch continues to draw a small amount of power regardless.
It's also worth knowing a genuinely useful warranty fact: genuine Kia batteries are covered for 24 months from the date of registration specifically for manufacturing defects.
