I wouldn’t even know where to start but I’m glad to see I’m not alone, although I’m very sorry you’re having similar issues! I bought a 2019 Subaru Forester Touring and had all of these issues plus some Eyesight-related safety issues, swapped that one for a 2020, and all of the problems have continued, some in different flavors. Tons and tons of CarPlay problems that would be too lengthy of a list to detail here easily. There was a recent “big“ update according to Subaru (at least for my model and year) but my car apparently already had it after wasting another day at the dealership. My phone is an iPhone 12 Pro and is also up-to-date. Subaru continues to the deny knowledge about these things, but I read the other day in a recently filed federal class action suit that they have known above some of this as far back as 2012. They settled one of the safety issue class action suits not that far back for $3.25 million. Many other infotainment deck issues started in 2018 when Samsung took over the HK. Overall, the vast majority of owners of all Subaru models seem to be incredibly happy and not have these issues, and then there are the rest of us. If you haven’t, I would strongly encourage you at least open a case ID and report it to SOA so they have your documentation. Do the best you can to take photos or video clips and keep good records, although at least in my experience even their highest corporate techs said they didn’t know what to suggest. After countless hours of research on how to fix the problem myself, I found the suggestion on an overseas YouTube channel to try a shorter cable, between 12 and 24 inches (24” still will allow you to handle the phone when needed)– – since even replacing the OEM Apple cable made no difference. The thinking here and from my consults with a few engineers outside of Subaru is that there may be some noise in some of the lines (also related to the BUS) or something not well-connected, where the shorter cable seemed to make some difference, although it didn’t fix everything. There are a whole bunch of phone/car/other resets in a particular order you can try, but for me this hasn’t solved much. I am considering getting rid of this car through Carmax/Edmunds because they are offering so much for used cars, and just trying something else altogether, although I had really hoped to stay with Subaru. Sure do wish you the best of luck and empathize greatly with your frustration!
