The 2015 kia optima does not have any power steering fluid because it has electronic power steering. your steering aid system is driven by an electric motor rather than the-classic hydraulic system. manufacturers have found that it is better to have an electric power steering system because there are less weak points in the system. electric power steering systems will never leak, and they are much smaller in size than the-classic hydraulic system. if you happen to notice that your steering feels heavier than normal then you will want to check the fuses and wiring to the power steering motor.
The 2015 kia optima power steering is electric it does not have a power steering pump or reservoir.
