Hi Steve, and welcome to the group.
I also purchased a 2010 XF 3.0 V6 about 2 years ago. To be honest, I don't think the problems are any different to that of any other car manufacturer.
However, I have replaced the cam belt, rear suspension arm, crossover valve, 4 new tyres, alternator pully and soon to have pads and discs all round to name but a few issues. These do add up over the years!! ££££££££
