Mercedes-Benz Australia has recalled 719 examples of its C-Class, GLC, and EQC model variants, citing a fault with the steering control unit.

The affected vehicles were sold between 3 February 2020 and 31 July 2021 (model year 2020).

The recall notice, lodged with the Australian Competition and Consumer Commission (ACCC), says: “Due to a manufacturing defect, the wiring harness of the steering control unit may be damaged. The damage can allow water or moisture into the wiring harness, which can cause a short circuit, resulting in a loss of electric power steering.

“A failure of the electric power steering would be indicated by a corresponding warning message in the instrument panel,” the notice continues.

“If a short circuit occurs, this may result in a loss of electric power steering or cause a vehicle fire. This can increase the risk of an accident, causing serious injury or death to vehicle occupants, other road users and bystanders.”

A spokesperson for Mercedes-Benz Australia told CarAdvice there have been no recorded instances of the fault in Australia, and the recall is purely precautionary.
