Last month my Infotainment system crashed and rebooted about 20 times over a 4 mile journey. In fact, it never really got going at all throughout the whole trip. Oddly, it worked perfectly on the return leg about an hour later!
Fortunately, I was able to produce video evidence so the dealership immediately accepted there was an issue, even though they couldn't reproduce it. They have updated the software from 1896 to 1899 but I still get the occasional crash (though not as bad as it was), so I suspect that it's going to have to be a hardware replacement on my next visit.
