Some Hyundai Elantra owners report experiencing loud knocking noises from the steering wheel, particularly during turns, often accompanied by a jerking motion. Additionally, many owners have faced unexpected loss of power steering assist due to failures in the electronic control system unit, which can lead to significant handling and control issues. Reports indicate widespread problems with the electric power steering, including disabled assist and illuminated power steering warning lights. Although Hyundai does not classify the loss of power steering assist as a safety-related defect in the U.S., it is crucial for owners to address any steering issues immediately, as electronic power steering locking up can pose a serious safety risk, especially when cruise control is engaged. Furthermore, a recall has been issued for certain models due to potential electrical shorts in the Motor Driven Power Steering (MDPS) assembly, which could lead to sudden loss of power steering assist and increase the risk of crashes or injuries.
