Advice on half shaft... buying 2018 S75D

[gilliambot]

Thinking about taking the plunge and going electric. Looking at 2018 model S 75D. There is one from a dealer near me that ticks all the boxes but I have been told that the half shaft has been replaced twice (under warranty). Is this a major red flag? I have heard rumours of the half shaft issue with Model S cars. Anyone know if there is an aftermarket permanent fix? Or if some way of avoiding wearing out these half shafts? Cheers
