I used to drive for five years (2015-2020) a 2009 naturally aspirated petrol Jaguar XF and it had zero issues except a single vacuum hose leak during my 100 000 kilometers (from 120 000 to 220 000) or so. The original rear upper wishbone arms were replaced and no more than expected normal wear & tear brake part replacements were needed. I still sometimes think that I'd like to have one again because in my opinion it was a quite nice and comfortable ride and turned out to be very good value as a used vehicle!

Maybe I had some kind of exception or are there dramatic differences between models and engines?

We had a 2003 Jag S-Type, and it was as reliable as anything else we’ve had. Only had it for three years, bought used in 2006, and didn’t do anything to it. This was back in the days of Ford ownership, though, and it was really a Lincoln Something chassis with a Jag body and badges. Granted, that was a long time ago, but I imagine the underlying chassis has a lot to do with the reliability.
