Recall on curent GT4 . The whole gear box will be exchanged !! 

What is wrong with Porsche quality these days? They change engines and gearboxes all over the place... On the GT lines nonetheless.

 

The manufacturer of the gearbox for the GT4 changed the process for creating 3rd gear (welding on the splines), which resulted in some failures for some cars.  Primarily cars built in 2016 I believe (so all the early 2015 builds are fine).  Porsche had been replacing gearboxes with a fixed gear already, but I'm guessing they have worked out some deal with the supplier, and so the rest of them are being changed out as a precautionary measure.  Recall hasn't been announced in U.S. yet though, so we shall see.
