The company says affected vehicles will have the fastening screws replaced with optimised screws as a precautionary measure.
According to Porsche, the only indication of the loose screw connection is the smell of fuel in the cabin. Globally, 16,429 vehicles are affected.
Owners of the affected models will be contacted directly by Porsche Cars Australia (PCA) to arrange an appointment with the workshop. The repairs will be free of charge.
