u/Inner-Vermicelli-699

Was hoping to get some help with a diagnosis on an issue I've been having with my car. I drive a 2024 SEAT Ibiza and recently had very frequent Power steering faults where my steering wheel would lock up after any heavy turns. I refilled the power steering fluid and it has decreased the frequency of this but it still occurs and my car seems to struggle to start/ignite afterwards. Battery is also recently replaced. Could this be an electrical fault such as spark plugs or something completely different?
