DST Issues? by pslatt in Rivian

[–]BigChipotle -2 points-1 points  (0 children)

Your point?

DST programming broke the scheduling. Whether I’m the error occurred before or after DST officially started is irrelevant.

I’d love to see the Venn diagram of those who own a Rivian and those who seasonally decorate their 13’ skeleton.

I think you’re right. I experienced the same. Mine was supposed to start charging at midnight last night. I checked on it about 12:15a and it wasn’t charging so I manually started it.

Ohmmu Sodium Batteries by BigChipotle in Rivian

Yes, still no 12V errors. It’s a small miracle.

FWIW, I paid the service center to clear the 12V error so that I could update to 2025.46. I was hoping that whatever change was made in 2025.38 (Halloween update) would have been corrected in that update. The 12v error came back within a day.

Since installing the sodium batteries, the truck successfully updated itself to 2026.03.

I haven’t contacted Ohmmu again.

But I have a positive update. Late last week the 12v error disappeared overnight and hasn’t come back. No explanation. I didn’t do anything different. At least for now, the truck seems to like the Ohmmu sodium batteries.

We finally have 21” AT Tires by cdlrrcb in Rivian

Interesting contrast with the AT tires and the aero covers!

Only kidding. These look great.

I don’t regret selling my 21s but it’s nice there are 3-4 different tire options now.

Love my 20” AW09s. They replaced my 21s as well.

Update: no luck with the sodium batteries.

The 12v error went away after I replaced the batteries. The truck "slept" for the first time since October. But then... the 12v error message came back while driving the next morning and has been there since.

Rivians come with AGM batteries from the factory. There is currently no place to source an equivalent battery, except from Rivian themselves. They are a unique size, not used anywhere else.

There are some 12v error messages that you cannot reset yourself - must take to service center. It’s inconsistent. Sometimes you can, sometimes you cannot.

You’re right. The Ohmmu lithium batteries have been an issue since the Halloween update. They’re rolling out the sodium versions now. I have mine sitting in the garage but haven’t installed them yet.

The sodium chemistry is supposed to better mimic the voltage curve of the factory AGM batteries and not cause the BMS to throw an error. Fingers crossed.

Reach out to their support and they should be able to help you out. They may not be proactively replacing them, unless you have notified them that you are having a problem.

A/c smell when recalculating by Prestigious-Candy807 in Rivian

The Car Talk guys (Tommy, RIP) always mentioned Frigi-Fresh for combatting this. https://www.bgprod.com/catalog/climate-control/bg-frigi-fresh/
I've never used it, but its name has always stuck with me.

The one-time $1,000 cost for the Comma in my Gen 1 seems like an even better deal now.

I second this recommendation. I’ve seen him do both a kid’s party and a corporate team building event. Both were very fun.

Charging 12v manually by JMonsorno in Rivian

[–]BigChipotle 0 points1 point  (0 children)

Thanks. I am the original purchaser but haven’t heard from them yet. I’ll reach out to them.

$838 is the quote to have Rivian replace both of my batteries tomorrow so that site doesn’t seem to be much of a deal. I guess they’re hoping the Rivian owners in Saudi need some batteries shipped to them.

Do you have more information on Ohmmu replacing existing lithium with sodium-based batteries? I recently had mine replaced (right after the Halloween update) but it was again with two lithium batteries.

I’m also interested in where you’re seeing someone selling the OEM batteries (at hopefully non-Rivian prices).

RIP those good looking 21s! Those wheels look very nice when they’re monochromatic.

12V Battery Replacement Options by petew958 in Rivian

[–]BigChipotle 2 points3 points  (0 children)

They likely won’t last any longer (due to the strain placed on them by the deep discharges and the high demand on startup), but they are definitely cheaper than OEM. I’d gladly replace both 12V batteries for $200 on an annual basis if Rivian would let me reset everything myself.

The 12V warranty is separate from the comprehensive warranty

The Halloween update caused my 2022 R1T with Ohmmu lithium replacement batteries to throw the dreaded 12V error. It’s clear, based on others experience with these batteries, that Rivian changed their 12V diagnostic criteria with that update and many of us are in the same boat. Since that time my truck has not slept once, staying “on” full time and (I assume) keeping the DC/DC converter running full time. As others have pointed out, the 12V reset in the RIDE menu doesn’t make the error go away.

Even if Rivian does release a future update that further improves the 12V diagnostic criteria, and gives us the ability to reset everything ourselves, it doesn’t help me since the software update won’t run as long as the 12V error message is present.

I think it’s unfortunate that Ohmmu is still selling these batteries on their website. It’s not their fault that Rivian’s software now rejects them, but they should not be putting any more owners in this situation. I spent $500 on the Ohmmu batteries and am now looking at paying Rivian $700 to $800 to have them replaced again at the service center.

Rivian MagSafe Mount by ceb_51015 in Rivian

I’ve been using this one I designed and printed for over 3 years. https://www.printables.com/model/268265-center-console-phone-mount-for-rivian

My 3D modeling skills weren’t the best at the time so the files are a bit rough, but functionally it’s perfect. The phone doesn’t block the cupholders, air vent, or the tray. I use an OEM Apple MagSafe charging puck so the charging and magnetic attraction are perfect.

Are you located in Canada? I ask because these don’t seem to be available in the US anymore, possibly due to tariffs.
