I've had my '17 Sport Sedan non-navi for less than one week, and my radio presets mysteriously vanished as well on day #3. What's really weird is that my last three presets (16, 17, & 18) were all SXM stations and they were still in the presets, but 1 - 15 were "initialising." I was hoping this had something to do with the free Starlink trial I was given, but now that I see this thread, I am fearful I will be seeing this problem again. This is my first Subaru, and it is replacing a Honda Civic that I also bought new and is still running at 265K miles. Very few problems over the course of ownership, even with all those miles. I told my sales rep the day I bought this Subaru that this Impreza has a tough act to follow. Well, not off to a good start.
