Cruise control disabled [Update: faulty radar unit fixed, resolved issue]

[kms3]

Has anyone got this issue. Basically it has made my auto pilot and auto steering not working.

I opened a ticket. They analyzed my diagnostics and suggested takin an appointment. Now I am waiting for the appt.

Not to doubt their intuition/reasoning/diagnostics, but heck,
have you done the complete reset, first the display computer
two finger + brake pedal salute, then full power off with phone
in Airplane mode, and wait 3 full minutes?

Don’t need to hold brake pedal to do the reset.



The issue you are describing is a known bug right now with sentry mode in which upon turning on the vehicle, Sentry mode does not “release” the cameras so autopilot doesn’t function.

Turning off sentry mode and allowing Tesla to go to sleep (not just off, but asleep) will reset the issue.

As an aside, this is being heavily discussed in other threads so feel free to look around and search before posting.

I have the same issue, and have tried resets, turning Sentry on/off, leaving off. My Autopilot worked flawlessly until I got a software update about a month ago. My Autopilot now works about 10 percent of the time. Had a mobile tech come out yesterday and he thinks it is software related. I just got a software update a few days ago, but did not fix my issues. He did tell me about giving the “bug alert” voice command when the functions aren’t working and then texting my Tesla service guy about it. It apparently gives them a little more information about circumstances when it isn’t working. Hopefully yours (and mine) will work eventually.

I actually don't have Sentry mode turned on. What is going to sleep means? I know power off and UI reset.

By the way, I also researched other threads. Someone suggested hardware issue to be the cause which worries me.

I took an appointment with Tesla. They found a faulty front radar and replaced it. It is working fine now. Just sharing for the benefit of the group.

Thank you for following up and letting us know how this was resolved. Hopefully the new front radar last the life of the car.

I’m I’m shocked this is still an issue. I got this in April. Posted it on here and it was resolved. Just surprised they still haven’t fixed it

 

[Fernand]

Fixed what exactly? Needing to reset the whole machine
right after an update now and then?

Finally took it in for service, and it took 2 days to fix. They ended up putting in a “car computer” replacement and it is finally working again. Not sure what the issue was, but happy it is working again.

I just had this. Booked a service appt (earliest one was in mid December!) but now the error message has gone away and the autopilot is working.
I've also had an intermittent warning about brake fluid (on a brand new car).
The common factor in all cases is that the car was recently very wet. First few times due to downpours, last one due to a jet wash. No idea if that is a coincidence or not.
