Mine was like... a day... of warning
Well that’s real bad news because I need a vehicle and I’m using it. Hope I don’t get stranded
My R1T had that warning for about a week before I could get it to a service center appointment. Was able to drive around fine, but there is always the chance it'll just die.
So, my R1S displayed red 12v icon and app instructed replace 12V battery. Mobile service replaced. Within 30 minutes of driving, “system failure” alert occurred. Towed to Gaithersburg. Now, waiting for resolution within the next 14 days. Anyone have any similar experience and what was the cause of the issue?UPDATE:
Nothing major but I had asked to see if I could get my mobile service date pushed up and the answer was no, so May 10th remains the service date.
My larger concern now is where the primary battery will be by the time that happens. I keep the max charge at 60% which is more than enough for any of my local trips and enough to reach any family/friends in an emergency situation without requiring any additional charging (that was basically my prime criteria for setting max charge - as low as I could go while knowing if I needed to jump in and get somewhere in an emergency I could still make it there (plus a 30-40 mile surplus). Anyway...
I am one of the people with fairly consistent 2-3% daily vampire drain. Sometimes a little less, but 2% a day is a fairly safe number. This incident happened somewhere overnight around the 15/16th of April, my last vehicle check-in was 59% charge. it has been unable to initiate charge since that point - it's just dead.
So if we go with 2% per day it will be ~25 days since the battery saw any kind of charging - so...main battery pack could be under 10% remaining. If we go 3% or even just 2.5%... we're in trouble
Now there are things that likely mitigate this - I have to assume there is some kind of HARD shutdown to preserve the battery pack at like 1-2% remaining charge. And we know there is surplus capacity in the pack such that when the vehicle "usable" amount is 0% the pack itself is not ENTIRELY drained, it's just very low. Further... with the 12v system dead and no phoning home or other systems waking the vehicle - it's possible that vampire drain is actually significantly reduced and there will only have been minimal losses. One concern I have about that though is if there is some kind of "fault" and the BMS is trying to REALLY get that 12V system up and running again and wasting a bunch of energy pumping into it.
But I guess this is all a bunch of unknowns at this point... I am not aware of anyone with 12V issues who didn't get towed or otherwise serviced pretty quickly. And I'm aware of people leaving (functioning) vehicles for 3-4 weeks only to find significant vampire drain - I don't know of any reported cases here of 12V failure AND 3-4 weeks sitting idle without charge. Maybe I missed it, or maybe I'm the first. Either way this is what's troubling me now. Is the pack itself going to suffer in some way from extremely low discharge? And I know this will be on Rivian to repair... but all the same, I just want the vehicle back and working. Waiting for a full pack swap is not something I'm terribly excited about.
All I can do at this point is wait and see. So I will update again on the 10th when service happens. Just wanted to let people know that is now confirmed as the soonest they can get to it.
Almost certainly it won't if it's similar to any of the other 12v issues most folks have seen. But I bet the SC finds a way to make a mobile appt THEN - sadly.
Get on the phone and insist on a mobile appointment. in the meantime, keep it plugged in to an L2 charger every time you parking it for an extended period of time (work/home).
Mine was plugged in and it did NOT save it... but I know it has helped for others so hopefully in this case it will
Hypothetical. I've not had any 12V issues (knock on wood--though I do suspect something is amiss given the amount of vampire drain I see even when plugged in)...
Mind you, I said "L2 charger" meaning a AC 240v outlet
If plugged in with a set limit (let's say 70%) but once that limit is reached you left your truck plugged in, it will still draw some power to charge the 12V and also keep other things running at the truck **when needed**.
While this is a relatively minor thing to deal with now, WHERE it happened is the real issue. It's going to be an absolute nightmare to try and get this serviced.
The garage at my place is entirely unreachable for any flatbed to tow. The garage it's in it barely squeaks into and the drink area is inaccessible.
I am hoping it can be jumped from the rear well enough to let it back out a bit and have mobile service replace the 12v bits - but if that doesn't work this is going to get ugly, quickly
Couldn't get a mobile service appointment so I dropped by the local service center about 10am. They initally said it was going to take them until the end of business to complete and I would get ride credits (UBER I'm sure). I told them I drove 1.5 hrs to get to them and would require 3 hours of uber rides and a complete waste of productivity if that were the only way, and the main reason I wanted a mobile appointment. Ultimately they were able to get my vehicle done in about 2 hours, maybe a touch less than, I left the SC around noon.
