I have Hyundai Elantra 2016 model.

This car is totally messing up with a lot of codes popping up.

The car steering will drive smoothly and after some times you will see the steering warning light on your dashboard and steering becomes stiff, until you scan and clear the error codes.

I have replace the power steering rack but still the problem is still there.

This are the codes am getting
