Tail lights keep blinking

[ER1T]

Can't agree more with you. Like I posted, I immediately realized there was an issue that warranted an urgent call, but after I squared that down was when I decided to search here and the rest is history.

Good collective thinking, and I'm sure this was helpful

Whilst I wait for my broken truck to be fixed, a few thoughts came to me:

Absolutely agree that the forum is/was a fabulous place to get real time information and help.

This is the 2nd software update failure of my recollection, since taking ownership. This has to improve. Those of us who work in IT know there should be multiple layers of testing before any updates reach the customer.

The Rivian customer support line and service center employees should be in the loop, before the customer. They should be told prior to software pushes (full or incremental), of potential issues to come. Everyone I talked to had no idea of what was happening.

All updates should have a “update now or later” option. I feel for those who had this happen while on vacation, or live hours away from a SC.

Saying all this to help the company I believe in, go from being GREAT to being absolutely OUTSTANDING

While I personally 100% agree with you, I think in this case (I have no way to back my statement here btw) was something that was pushed or updated long ago and just failed today on some vehicles that met certain conditions that triggered the flaw.

Mine is back to normal now and sleeping. Thanks to everyone for contributing but kinda weird that they fixed it and unlikely to ever explain what actually happened. I'll leave my SC appointment open until next week just in case.

Cloud related tells me there was a connectivity problem on the backend that could be fixed easily. Could be an authentication or certificate issue of some sort. Once that got updated, the affected vehicles could connect to the backend again. No OTA needed for that.

However, it exposed a logic problem somewhere in the vehicle software that resulted in an infinite re-try that didn’t recognize a sleep command. Hence the need to push an OTA parch to solve it from the vehicle side.

I installed 2025.22.01. Did a hard reset. The truck finally went to sleep just now. Was awake for 2.5 hrs. after the update.
Cover still won't close. I'll leave my appointment open.

same here. My truck normally go to sleep within a few minutes. After the latest update, it doesn't go to sleep. Did a hard reset and that fixed it.

Mine fixed up yesterday as well (I think that, if they had to send anything specific, it was sent during the day while I was out and about away from the truck). Arrived home and blinking had ceased and truck went right to sleep.

oh and still on 2025.18.01. I'm a non-connect+ person so will probably be a few more days til I get the latest update

well, after 4 days? of blinking, my new 12V battery (replaced earlier this year) is throwing up warnings to be replaced. thanks rivian!!

I wonder if Rivian will replace batteries preemptively if asked

Oh man. I'm so sorry to hear this. I hope you plan on handing them every page of information on this thread when you go to get it it replaced. Let us know what they say.

For anyone else who's still having this issue, I've seen a few threads about back-feeding the 12V through the OBD port. I wonder if that would help? Of course, in the amount of time it would take to order the right adapter the batteries will probably be toast.

Maybe just straight-up disconnect the 12V battery for now, if you can?

Disconnect the 12v would shut the vehicle down most likely. Feeding 12v I would only go directly through battery terminals as you'll eat quite a bit of current

Well... Brought my R1T home back (in spite of what the SC told me, they wanted to keep it until Monday to START the diagnosis process...)

Just parked it in my garage and she's already sleeping. Tonneau cover is again working, I'll probably run a 12V health check tonight.

My Veredict:

• Customer Service over the phone: A+
  • They quickly acknowledge my sense of urgency (12V health, HV batt drain, trip coming up Monday 7/21st) and got me checked into the Dallas SC for the next day.
• Rivian Software Team: A
  • They had a bug (s**t happens) acted quickly and had a quick fix pushed OTA. Won't give them an A+ just because I'm a nerd and I would've liked more transparency during and after the fix (What happened? what was fixed? which module was affected?
• Dallas SC: C-
  • This is a tough one. They were awesome on the check-in, providing me with an immediate rental which was swapped for an R1S just 24hrs later. They made it very pleasant and satisfactory, but..
  • I communicated to them EVERY piece of information I knew for sure (not what I or we suspected, but facts), such as "I see ~10 with the same issue, now are 20 confirmed, now 30, please escalate with Rivian. I see there are R1T and S, Tonneau cover is a symptom for those who have a PTC. Someone in this SC said they're pushing an OTA firmware", etc,etc. I wanted them to be ahead of the game and act accordingly.
  • Rivian SC ignored all that and I got a message at around 11am CST that got me livid which stated that "my truck is on the queue and will be diagnosed ~7/21st". Replied with a "CALL ME ASAP" message.
  • They SHOULD HAVE communicated with Rivian and take my truck out of Service Mode and test if it's fixed or not "automagically".
  • Took my R1S loaner, drove down to Dallas asked them to pull the vehicle and waited. 26 mins later I tested the PTC (it closed now, didn't open, did a reset and all working as expected) and pointed to it saying "you see, It's fixed!". Allowed a few mins and showed "sleeping" for more than 1 minute and said "Check me out, I'm fixed".

I was upset because they SHOULD have been communications in between Rivian Software Corp team and the SC (Not sure where the failure was). They should've kicked me out of their lot yesterday afternoon. By their procedures, my truck would have been taking space, hours from a tech, a loaner and a few more things for something that was already fixed. That was unacceptable to me.

Anyway. She's sleeping at home now (took me 15 mins to write this it seems) and will test further during the next couple of days to confirm, I have a 2000mi trip to make Monday-Friday next week!

Service centre told me to try the tonneau cover reset procedure. Tried it about 10 times without any luck. I was just about to give up but decided to try a soft reset. (I had done several hard resets before without luck.) Well it finally worked! So back to normal operations. Thanks to everyone who contributed to this thread. Misery loves company.
