Hello today when i was driving my car probably doing 20km the steering wheel suddenly got stiff and the engine light came on so immediately stop on the side o the road and switched the car off for only 10 sec or so , when i start it again it cranked a bit than now but it came on and steering wheel was soft again and no engine light i drove back home 5km and on my way home the oil light came on but disappeared after 2 second..when the car is on the engine fan is always on and very load when when it's idling, before my fan only gets loud after along trip but it's always loud. How much will the repairs cost thank you
