Porsche has announced that it is recalling all 918 Spyder models due to a mix-up of screws used to secure the seatbelt system.

Exactly 918 units of the hybrid hypercar – which has been recalled for various reasons before – were produced by the Volkswagen-backed German automaker from 2013 to 2015.

According to a statement, the "original parts catalogue for the 918 Spyder inadvertently transposed the locations for the screws which respectively secure the seatbelt mount and the belt reel mount".

These screws, Porsche points out, are "one-time-use only" and are not the same.

"We cannot rule out the possibility that, due to the mistake in the catalogue, technicians who had to work on those components might have been led to install the wrong screw in the wrong location," the statement explained.

In such an event, the function of the seatbelt system could obviously be impaired in a crash.

"To prevent this risk, the fastening screws on the seatbelt mount and on the belt reel on all 918 Spyder vehicles will be checked. Depending upon the result of the check, Porsche might replace the screws on some vehicles."

And the mistake in the parts catalogue? Well, Porsche sheepishly says that has already been corrected.
