Cruise Control Not Available

[Midnightsun]

My cruise control (autopilot) has been out for some time now. Keep getting not available and reduced radar visibility warnings when I try to activate it. Do have a service appointment on the 28th but just putting feelers out if other have had this issue on the 2021+ refresh.

If you didn't already try rebooting, do that.

i dono about for the newer cars but sometimes i get those errors when the sun hits the windshield cam at the right angle when its parked but as soon as i move its fine.
Also i get that error in the winter when the front radar thing on the bumper gets too much snow accumulated in it.

I'd try a brake pedal reboot and if that doesn't work do a super reboot and disconnect the pos of the 12v and then pull the firemans loop for about 15 min before reassembly then see if its solved (do both of these unplugged from charging)

I get it often. They replaced the radar unit and it helped, but I still get it from time to time. Seems to go away after driving for a bit though.

Something bigger going on as I don't even get external car visualization on the drivers screen any more. Got a feeling the radar is out.

Try to reset camera calibration to see if it helps, but yeah you gotta go through service and pray the part is available.

Try a 12V reset?

There's some background here that might be related:

Wonky 2022.8.2?

Hi all, I seemed to notice some things yesterday following this update (which I kinda regret doing) - it seems garbage cans now flash on the screen, and my autopilot went from working reliably to rarely working, and when it will engage, it seems to want me to get my hands on that yoke right...

This just started happening to my Model 3 yesterday. (Cruise control, autopilot, emergency breaking all unavailable w/ reduced visibility warning and no FSD visualization.) Read on another thread to remove the USB drive for sentry, turn sentry off, and let the car sleep for a little bit. Somehow this fixed my issue. Must be a software problem with the latest round of updates. I haven't tried reinstalling the drive to see if the fix remains.

They replaced the radar unit. All is good.
