Mine still does not go to sleep, and the other night I randomly checked the garage and my car was blowing air from the vents with no one inside.

That's definitely odd and if it's not fixed after a reset, you should contact the Customer Support ASAP

Gen2 R1T owner searching for answers on a similar/same issue. Two days ago I noticed the rear lights (just the turn signal portions, L and R, not the whole bar) blinking about every 60 seconds or so. I only noticed this as I was parked outside at night as we are traveling away from home. Then I noticed the abnormally large system use of the battery. Last night for example I lost a full 5% SoC. I uploaded diagnostics then did a hard reset. Seems to be sleeping fine now, but the SC says it needs to come in even after looking at the diagnostics I uploaded.

Taking to SC on Friday. Not entirely sure if this is the same issue from this thread or something different.

Do you have a Rivian Roamer account? if not, create one (free should work but I would definititely consider the pay subscription and it adds lots of value for the money)and monitor your truck for 24hrs and watch the Activity bar on RivianRoamer's dashboard:
Rivian R1T R1S Tail lights keep blinking 1775064827400-37


You can clearly see the SLEEP/ Driving/ AWAKE /SLEEP cycle mine has here. This is perfectly normal.
But, if it goes (let's say) 12hrs straight without a long sleep session, then you might have an issue.

Last time it was solved by a OTA pushed update (no involvement from the service center) and I believe it only affected Gen1.

One test I would do, is try opening and closing the Tonneau Cover and see if that works normally (mine and several others didn't operate normally while having this issue).

This might not solve your issue but it'll give you more info on what you're dealing with (Same issue as last time? maybe a new one?)

Finally, if you want to sign-up for Rivian Roamer and you would like to use my referral code, https://rivianroamer.com/join?with=mudo you can do so and we both get a $5 discount :)

Keep us posted!!

Thank you.

I do have an RR account, just not the paid one (yet) to see the deeper data.

the tonneau works fine. No issues.

Wonder if this is a new thing.

Cool, then monitor the sleep time during the day today and if it doesn't sleep at all, then I would keep it plugged into an L2 charger. Otherwise the 12V battery will suffer

If the vehicle is not going to sleep, then yes - you're going to see that high drain and potential 12v battery damage. RR, ElectraFi, etc., can help you monitor.

Iirc, this issue last year was caused by vehicles trying (and failing) to communicate with the cloud server. It was a back-end issue that they resolved quietly, but not before several people needed their 12v replaced.

Here's how normal sleep cycles look on ElectraFi, for reference:

Thank you.

Updates on my end:

One thing I noticed yesterday was the vehicle was not getting up to the full charge that it was set to (70%). It would get to 69% and then it seemed the connection/handshake failed - the green light turned to a white flashing light.

The charger I’m using is not connected to WiFi any longer as it’s not supported (an old Enel X). Not sure WiFi would matter, but perhaps there was a fault with the charger or there was a fault with the truck when completing a charge that caused the problem with the sleep cycle.

Also yesterday, I got into the truck and also noticed the location of the truck was about 1/4 mile from where it was actually parked. Not sure of the reason.

After getting to my truck first thing yesterday morning and seeing the 5% SoC loss, I logged a diagnostic to Rivian and then did a hard reset. The SC says they looked at the diagnostic and want me to come in for service.

Last night when I returned to the property I’m at, I set a high SoC of 95% as I’m driving a long distance today. This morning, it’s charged fine, sleeping, no SoC loss, no blinking tail lights, and the charging circle on the truck is off just like normal after a successful charge.

Not sure if the hard reset fixed it or what’s up.

FWIW - Update.

I picked up the truck last night from the service center. The report from the technician was that they could not diagnose the blinking tail lights. They indicated that was a normal function when a key or phone is within range for proximity functionality. In my case, there was no key or phone within range for that to trigger, and it also occurred after I turned off the proximity functionality.

Not posted previously, but on my way back from my trip my parking and proximity sensors all started to trip/fail. Adaptive, cruise and Autonomy+ was not functional.

Luckily, my service appointment was the next day so I added this to my ticket. I did a soft reset when I got home. That temporarily solved the problem, but on my way up to the service center the same errors occurred again. The technician said that there is a software issue that they’ve identified and are working with vendor to fix it through a future OTA software update. When I drove home last night from the service center, a two hour trip, everything worked fine.

Not really sure what to make of this other than wait to see if it happens again.

Might be kind of the same as the other time but wasn't widespread this time... Maybe?

Certainly a possibility. The last response I got from the service center was that they can push an individual OTA just to my truck for whatever software fixes necessary. He did not think it was widespread (or had no information to support it being widespread).
