I watched the video on the single version replacement and it looks pretty easy to do your self. I would 100% replace it with a Litium ion based version.

Why? There's a whole lot of risk and very little gain from changing LV battery chemistries. LiFEPO4 batteries are not meant to be subjected to constant cycling like these vehicles subject their 12V batteries to. I would be surprised if lithium batteries are more reliable than a well made AGM battery in this application.I watched the video on the single version replacement and it looks pretty easy to do your self.

Gen 2? Isn’t it under the seat on Gen 2 and you have to take the whole seat out to replace?I watched the video on the single version replacement and it looks pretty easy to do your self. I would 100% replace it with a Litium ion based version.
Please google the topic before commenting. Most Evs have switched to Li for low voltage and it’s a drop in. Tesla did this 4 years ago and OHM makes one for the Rivian. Infect the chemistry and design is much better than lead acid in an EV.Why? There's a whole lot of risk and very little gain from changing LV battery chemistries.

Yeah, with battery management systems designed for LiFEPO4, sure. Your vehicle does not have a BMS designed for anything other than AGM.Please google the topic before commenting.

Lord knows they need an enormous SC near socal. I give eastvale 100% and the shitty battery replacement process 0%.Holy cow. That's an enormous SC.
My 12V was replaced last week, at Lake Forest SC, under warranty. Did not have any warnings or problems with the original. It's something they added to my service ticket as a active measure/campaign, along with checking and retightening the front knuckle-to-hub bolts.

I did, but its out of warranty. I spoke to the service advisor at length and talked to her supervisor. They were both very nice, so I'm not going to be an asshole about it. I could tell their hands were tied. I did push on the fact that I can't buy it and put it in myself , and I'll also relay that to Rivian customer service. If enough people get upset, maybe they'll change their policy.Since you were so close out of warranty they should have worked with you on some coverage. I recommend others in same situation push harder for some coverage. I assume there has to be some similar batteries available in the market if they weren’t willing to support but have only seen the lithium alternative posted on this forum before.
Yeah I was slightly upset about it. This is the gen1 with the 2 batteries. I think gen2 labor will be worse but the parts will be less given it has 1 battery.Pretty ridiculous that it costs $700-$800 to replace these dogsh** batteries that are known to be highly issue prone.
Complain to your state attorney general's office with them refusing to sell parts. Rivian is not interested in you servicing your own car.I did, but its out of warranty.

Common repairs are always cheaper than a new vehicle or a lease. Even Rivian bullshit like what the op went through.Stuff like this is why I wish they offered leases in the beginning. Hopefully Rivian will give me a decent trade in for whenever Gen 3 is out so I don't have to deal with out of warranty repair.
Yeah, very worried about out of warranty repair on the suspension. I'm doing some research on who is replacing the suspension and when.Stuff like this is why I wish they offered leases in the beginning.

It's not even difficult to replace. You just can't easily get them.So, it's very much like an ICE battery except for the difficulty replacing it. Interesting.
The Gen1 2023-2024 single battery version has a $400 capacitor, labeled as an "isolator", be grateful you don't need to replace that. Alas, you can't replace your 2nd battery with it. There's some sort of 3-pin plug that goes into the isolator, something the 2-battery system lacks, so it likely wouldn't function the same.Total cost was $717.18 for the 12V batteries (2 of them). Parts 479.98, labor 200, plus tax. I'm not in love with this. They don't let you replace them on your own. That means I paid ~$29 per month of ownership for my 12V batteries. For reference, a Lamborghini Aventador battery is ~$180-250 for parts only and can be replaced by yourself. Model X is from $120-200 and easily done DIY.
There's nothing special in the service manual regarding "post battery calibration" or anything of the like.Prepare to be barraged by comments saying the same thing, but yeah - you can do it yourself - there's videos on YouTube that show how. It is more difficult than a legacy ICE car, in particular if you have a vehicle with the dual 12V batteries. But it's do-able.
Imo Rivian really needs to start publishing their own service & repair documentation, but that's a whole other conversation.![]()
