Since 2019.5.15 update ,new issue. When shifting P->R the backup camera sometimes waits a couple of seconds before activating. Black screen until then. I've seen other black screen situations, but it recovers pretty quickly, so I haven't figured out any association.
I have had issues with the right stalk since I got the car in December, where it sometimes doesn't accept a request to enter AutoSteer. Troubling because if I'm in Cruise I THINK I'm now in Autosteer, but then I realize I'm not. Ouch. It's also failed to enter Reverse a few times. It's like the sensor polling misses the event or the sensor is intermittent. I'll have to take it in at some point soon.
