Toyota Australia has issued a recall of more than 324,000 vehicles.
Cars affected include Prius, Prius V, Corolla and Rukus vehicles built between October 2008 and February 2015.
The recall is due to the possibility that a crack may develop on the fuel suction plate assembled to the fuel tank.

If this occurs, the crack could expand over time and fuel may eventually leak when the vehicle has a full tank of petrol.
Fuel or fuel vapor in the presence of an ignition source could increase the risk of a vehicle fire.
There have been nine reported cases in Australia of a crack developing in Corolla vehicles.
The automotive company are also recalling 4560 previous generation Prius vehicles built between April 2009 and April 2012.
The recall is due to the possibility that there may be a small crack in the weld area joining the curtain shield airbag inflator chambers.
If this happens, the crack may grow over time and lead to the separation of the airbag inflator chambers.
In a statement on their website, Toyota says if an inflator separates, the curtain shield airbags could partially deploy and in limited circumstances one or both sections of the inflator could enter the interior of the vehicle. If an occupant is present in the vehicle, there may be an increased risk of injury.
Toyota Australia will be contacting all affected vehicle owners by mail.
