Jaguars are not known for reliability. Indeed, I got rid of my 2012 XJ L after its coolant system failed catastrophically one too many times (which was "two times" - first one, okay, so be it, happens again, no thank you).
However, at some point the dealer bricked the entertainment console (of course tied into everything else), and it was an all in one unit that they had to replace...
I am near Seattle. "Well crap, how long is that going to take?" (thinking the car is several years old at this point, and not a high volume of sales). "Oh, we should be able to have a new unit installed by the end of tomorrow, unless we have to get it sent from England, in which case, end of day after tomorrow".
