I was away for some time but in the meantime my car went to the workshop as scheduled to see what they would say about the reported bugs.
The car was there for 3 days under "observation" and left the same, they did nothing...
After another complaint, the head of the workshop came to talk to me and now I have some news.
He confirmed to me that the brand will make a service recall to the first vehicles sold and that have the first software versions.
He confirmed that they will probably replace the 12v battery and do the first software upgrade.
Only after these interventions the car will start making OTA updates.
Newer cars should already do it.
However, as for my complaints (screen resets itself on the go, charging routines don't work, etc.), they spoke to the manufacturer and gave me a tip that would fix these bugs. And would you believe it, it worked!?
It doesn't make much sense, but what causes the bugs in versions 0796 is the "Automatic selection of station logos" function in the radio settings.
Disabling this, the bugs stop happening and even the charging routines started working!!!
For those who have an old software version, here's the tip.
In the meantime I will have to wait for their call to see if they update my software once and for all.
P.S. meanwhile I also ran out of AC. No longer providing cold air.
Returned to the workshop and was out of AC gas... with 4000km...
They said it must have been a factory error and it wasn't full...
