I've had the Xs (upgraded from 7) for about 3 weeks now and have had to re-pair it with my car (2013 Hyundai Elantra -- dont get jealous) exactly every 2 days. After the first week, I started keep a log to make sure I wasn't going crazy. When I get in the car, I get a message from the dash that says "Pairing Failed." I have to manually delete my phone from the source list in the car, delete the car from the source list on my phone, and re-pair. With my iPhone 7, I only had to re-pair when I got a new car battery. Maybe 2-3 times total in 2 years. I've reached out to Apple support, who ran a remote diagnostic and said that the bluetooth hardware is functioning as expected (duh). Suggested I reach out to Hyundai and ask about a firmware update — for a 6 year old car. I'm sure they'll get right on that. Meanwhile the only variable that has changed is the phone. Anyway else have similar issues? It's kind of strange that it's every 2 days...not some random duration.
