Tesla owner here. Many stories of that with them, and the latest autosteer update was a major downgrade.

Thankfully they mostly break the UI. Though my auto wipers got really bad recently. The body control electronics are pretty solid. I mean, you could lock/unlock, drive the car without the tablet. Not that regulators would approve of it.

Rivian, Tesla, Ford (Mustang EVs) all have had bad OTA software shipped to them. The problem will continue to get worse as cars become mostly software defined.
