In a short statement overnight, Subaru has confirmed vehicle production has recommenced at its factories in Japan.
With the company having secured "countermeasure parts" for these vehicles, the Gunma production line has started up again.
According to Subaru, when the component malfunctions, the steering control light on the dashboard come on, and power assistance is cut off, making the wheel much heavier than normal.
The automaker has advised customers who experience this problem to "stop driving immediately [and] contact your local Subaru dealer".
Subaru Australia has confirmed to CarAdvice "no vehicles in customers hands or in Australian dealer stock are affected".
Some vehicles with the faulty component may be on ships heading to Australia, but the company says they will be rectified before they end up in dealerships or in customers' driveways.
