Arkana hybrid engine power loss

Reduced power and error codes usually point to ECU problems. Did you try a system reset? Sometimes that clears things up, but it could also be a sign of a deeper issue. What kind of error code are you getting?

Thanks for the quick reply. I haven't tried a system reset yet. Is that something I can do myself, or is it best left to a professional? I'm not sure about the exact error code, but it mentioned something about the engine control.

If it's pointing to the ECU, and a reset doesn't fix it, it might be a defective main relay. Those can cause all sorts of weird engine performance issues. You're probably best off taking it to a workshop to get it properly diagnosed.

Thanks, I appreciate the advice. I took it to a mechanic, and you were spot on – it was the main relay! Repair cost was around 120€. Runs like new again.
