Recently upgraded to 2019.28.3 from 2018.24.4. After the upgrade, AP started to error out randomly and require me to take over. This is on roads where it never previously had an issue. Yesterday while driving with AP enabled the car alerted me to take over. After taking over there were warnings that cruise control and automatic emergency breaking were disabled. I parked and rebooted the screen with the two scroll wheels but the warnings persisted. I then shutdown the car and waited two minutes before starting up again. The errors went away. However, now the GPS is stuck at the location I was parked and no longer updates. The instrumentation cluster shows my car but not any cars near me or the lane markings. A firmware update was available yesterday, presumably 2019.28.3.1, but it failed both upgrade attempts. Now I cannot use AP properly.
