I have a kia forte 2009 but my EPS dash light is always on and my steering is OK, My question is should I ignore this light and continue driving?
No, you should not ignore it. Steering is with the brakes the most important safety critical system in the car. Either steering or brakes failing can be fatal.
The systems are usually designed in such a manner that they don't fail by suddenly turning violently to the left when there's oncoming traffic, but even the mere possibility of this happening would be a major concern.
If you ignore it, you'll soon find the car failed the next mandatory inspection.
However, do note that EPS and ESP are two different things, as user9181 correctly noticed. Even the ESP light would usually mean the inspection is failed.
