The automaker says the fastening screws for the fuel collection pipes can shear off and cause gas to leak in the engine compartment, but no reports of fires related to the gas leaks have been received.
Porsche received a report in March 2016 about an incident where fuel leaked due to a busted fastening screw in the fuel collection pipes. After gathering the affected parts, engineers determined a crack was caused by corrosion of the threads, likely caused by exposure to "extreme conditions."
No other reports were received, so engineers thought it was an isolated event due to the Porsche being used on a dirty race track. However, another report came in describing the same gas leaks, then a third and fourth showing broken fastening screws.
The automaker also realized three of those reports involved cars used on the same race track in Britain, so engineers performed stress tests on the parts and noticed cracks appearing due to corrosion.
A recall date hasn't been announced, but dealers will need to install improved fastening screws to make sure fuel doesn't leak.
