The 12v battery is a known weak design that can cause all those cascading and strange errors. Did you see any messages about the 12v? This is why there is a recall in progress in the EU, and soon in the US but here they are calling it an "update". Its also why they changed the type of battery and the BMS in 22 and 23 cars. Do you have a voltmeter or an OBD dongle to check it?
