The Bavarian company reports the fuel tank ventilation line may not be correctly located, and could wear through if it rubs against the body of the vehicle.
If the condition occurs, fuel vapour may be released into the atmosphere.
Affected i3 REx models were sold from 1 July 2014 through 30 November 2016.
Owners of the recalled vehicles will be contacted by BMW Australia or by a BMW dealer. Customers can also contact their local dealer or 1800 813 299 to arrange the inspection and repair of their i3.
