Kia Optima System Off - Today i got a check hybrid system. Stop vehicle and turn off engine i shut it off and it would not start. Got the message to check hybrid system and turn off engine. Its manual about 80000. It's a 2025 kia optima hybrid. Sorry to be the first to reply as i don't know much and unsure if yours has this but have you checked any of the stop and go system for issues? It's basically, it's a fail safe. It has electronically inhibited you from starting it so that you don't start a fire. The most likely cause is there's a power relay assembly in the trunk.
