These problems plague so many new cars it's incredible. I know people who don't want to buy a new Mercedes S-class, but are instead looking for low-mileage units of the previous generation because it has the same issues. I don't know what the fuck is going on with cars these last few years but the manufacturers need to wake up.
I've had the "Complete Center Screen Malfunction" issue on my Polestar 2 (though an infotainment reboot "fixed" it.
But climate controls disappearing and climate shutting off during infotainment reboots is already pretty atrocious.
I have the "backup camera unavailable" issue, and despite multiple recalls and attempts to fix in software... the issue persists.
There are other issues, but none as bad as he's seen with his EX90!
