To be fully understanding.
This crash fault only manifests itself when route planning with a charging stop is activated
This affects all Taycan
All model years of J1.1
I ask because I have never required a route charging stop, so have not used Nav in this way. I have used destination Nav...
Interestingly 4 or 5 years ago, my Macan S experienced similar issues to this. Nav crashing (no charge planning of course - 3 litre ICE) and all on line services disappearing.
The vehicle was out of warranty but I contacted Porsche and a discussion ensued for a number of weeks and they agreed...
Heater and OBC are 'the luck of the draw'. New variations are developed all the time but they seem to keep failing, perhaps not a frquently as once was the case.
'Standard' 11kw charger is not immune but much less frequent than the 22kw one.
The good thing about my previous Macan S was that 'my' wheels were available in 21 summer, and 20/19 winter sizes in the same design. Sport Classics thus negating your issue.
I know, doesn't help...
