The recall notice, lodged with the Australian Competition and Consumer Commission (ACCC), says a fuel line connector may leak at “very high engine temperatures”.
Should the leak occur in the presence of an ignition source, it may result in a fire, increasing the risk of serious injury to vehicle occupants, other road users and property, according to the recall.
CarAdvice has been told there are "no known cases of this fault in Australia".
Porsche Australia says replacement parts will not be available until the end of July 2020, but it is contacting owners now to inform them of the recall.
