There can be an internal electrical failure- of the control module that will case the eps to fail and the steering failure message to illuminate on the dash. The module will often not communicate with a scanner to read any fault codes. The steering racks can also suffer from mechanical failure of different types.

The rack teeth can wear unevenly causing a knock when turning the steering wheel. As well as a knock when on bumpy ground. Water ingress can also be in issue that can cause the rack to make a grinding noise when turning the steering wheel.
