12 Volt Demons Caught Up With The Count

[Dark-Fx]

I blame The Count for this.

I decided to reset it in the RIDE menu and it's stayed away so far. I'm sure it'll come back though.

I may not be of royal pedigree, but I too have noticed the reversal of the mobile service policy of Rivian and it’s enough to get me to trade mine in. I’m shopping for deals right now and when I find one my R1S will be traded in.

Living 3 hours from a service center means that even minor annoyances are an all day affair. I didn’t spend this kind of money on this thing to be driving 12 hours to deal with repairs each time I have an issue.

I've always had to push them to do mobile service. Sometimes it meant waiting longer. I'm less than 30 minutes from my SC during non-traffic times though.

I have been running the Ohmmu sodium batteries (2 of them in my 2022 quad) for several months. I originally had the Ohmmu lithium batteries but Rivian didn’t like them after the Halloween 2025 update.

I believe this is when Rivian increased the 12v charging voltage and was a bit high for Lithium. High voltage will trigger the lithium battery internal BMS to stop the charge. Vehicle is not expecting this and must cause an issue and fault message.

Wow! I also got the 12V warning. About 9am Friday. 2022 LE R1T with every indication battery health was good then the sudden warning. I had a R2 test drive scheduled the next morning at the Franklin TN SC and they were able to replace the 12V batteries while we there. 63k miles on my truck and this is the third time the 12V have been replaced. After discovering this thread I’m thinking I shouldn’t have had to pay the $504 for the replacement even out of warranty.

The only good news is the service advisor said the customer pay 12 volts get a two year warranty vs one year if covered under the vehicle warranty. At my historical failure rate I will never have to buy another one because they have NEVER lasted two years.

I say mean to ask if the R2 would have the same ridiculous problem but forgot about it while there. Too many shiny new vehicles distract me!

This must be a software glitch.

This must be a software glitch.

I will be calling them and questioning why I had to pay for something that seems to have simultaneously infected a significant part of the fleet. My truck ain’t no garage queen. It’s driven daily and charged most days. If I can’t keep the 12V alive with normal use I’m not sure how anyone can.

Or how to make $10M+ quickly

I've always had to push them to do mobile service. Sometimes it meant waiting longer. I'm less than 30 minutes from my SC during non-traffic times though.

I tried. It never used to be a hassle living so far away from the service center; they defaulted to mobile first. Now it's clear their policy has shifted for them to save money. I get it, and it works when dealerships are in close enough proximity. That's not true for me, and I won't consider Rivian as a brand again until I have a service center within a reasonable distance. I'm hoping whatever I get next I can keep for a while, though.

Add me to the list of folks who received the 12V battery replacement notification this week -my notification arrived Friday afternoon.

No service appointments available until July 2nd.

This will be my 16th Service Center visit. Yeah! So excited!!!

5/60 Warranty doesn’t officially cover the 12V battery. At least now I don’t need to figure out what to do with that $500 burning a whole in my pocket.

Yeah, I also got the notification last week (while on vacation in Seattle…and my truck was charging in the Dulles parking garage…).

Rivian service offered the mobile option, but I don’t have an L2 charger at home, so I had to make an appointment at the SC. Got 2 weeks out (next Wednesday).

I've had to push for a mobile service as well, but I didn't have to push too hard. This was for a 12v replacement and a (previously) 15k mile inspection. And I live four hours away from a service center.

That being said, I believe that my area has a dedicated Mobile Service tech that gets parts from Seattle but bases in (or near) my city of residence.

All my options are ICE as well. I'd rather EV, but there's nothing out there that meets my needs ATM.

I've been pretty happy with my hybrid F150 even though it's a Ford. I might replace it with a new one and simply sell the R1S outright. I like having the propower 240V on the Ford. Plus with the Ford I am more incognito as it blends in with the millions of others on the road.

My story, on a trip 3k miles from home, got the replace 12 volt battery message this morning. Called the service number from the app. There are no available appointments at the Canton MA SC but the rep said they prioritize these issues, asked when I could get to the SC and they would call call ahead so they could be ready for me. Was a 30 minute drive, they knew who I was when I got here and are currently servicing the vehicle. Less than an hour from seeing the messaging and getting serviced.

Edit: Service completed, was back on the road in under an hour. Rivian service number through the app and the Canton, MA service center were both awesome. $581 for the replacement batteries and installation was a bit high but the customer care was great.
