After the last update (2020.44.10.1), the car suddenly stopped making any sounds, including turn signal sounds, navigation, etc. I tried rebooting it (by holding down both steering wheel buttons), and I noticed it took slightly longer than usual to reboot.
After it finished rebooting, it turns out that it had completely reset itself! It forgot its name, it forgot my entire profile, all of my preferences, home address, etc. Thank goodness it still remembered my key cards and phone pairing, but that's about it.
I managed to re-enter all of my preferences, but it still refuses to do any navigation, saying that navigation data isn't loaded and "service is required," also showing an error code of "ui_a010". Has anyone seen anything like this? Is it safe to drive it? The earliest service appointment I could get is three weeks from now.
