The BMW 3 Series G models were introduced in 2018 onwards uses a new design of electric power steering rack.
The G20 / G21 / G28 steering rack can fail for a variety of different reasons.
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 an issue that can cause the rack to make a grinding noise when turning the steering wheel.
The mounting bolts that secure the motor to the steering rack body can also shear this, in turn, causes the motor to come loose and even fall off of the rack in some cases.
This lisiting is for vehicles without variable sport steering
