I had a similar issue, except the car didn't start. After change of battery and charger the problem has not reoccured.

How was the weather when the "alarm storm" started? I have experienced similar several times, although not sure if absolutely all errors were present. It happens when driving in sleet or falling wet snow, with the slush on the road splattering onto the car's sensors. The alerts disappears, when conditions betters and it melts/dries up.

A lot of down time. Sometimes for ~ a week, sometimes for hour(s). A reset and login is usually necessary to get contact again.

I have sporadically had similar problems. Plugging in yields various odd reactions. In some cases plugging out and in again fixes the problem, in other cases more complex means have been necessary. In one case it behaved like in your video - plugged-in, the red light came on and stayed (-> unable to lock the plug according to the manual). After troubling for some time I were able to rectify the problem by using the charger for on ordinary 10 A power outlet. Plugging it in, the charging started as it should. Removing it and plugging in the cable from the charger – everything worked fine. In case there is an interworking problem (partly mechanical, party in the handshake) between the charger and the car, I attach a photo of the charger label.
