I’ve cleaned and rechecked the oil a few times and it’s stayed at this level, could this cause issues?

The car has shown a lot of errors today, and now is running rough on idle, revs keep dropping. It’s showing errors: HDC not available system fault. Park brake fault. Stability control not available drive with care. AEB not available. Forward alert not available.

I also checked battery with the engine off and it was at 12.5V and with the engine on, at 14.5V.

I don’t know much else or if anything is related, any advice if this is drivable for now or if it needs looked at properly would be great, thank you!
