Confirmed: Newer production R1 only have a single 12v battery, but...

[rhuber]

Great. So just unplug neutral and wait. I feel like this is kind of an old procedure from ICE cars.

You don't have to wait. You just pull the ground and put it right back. Don't do it before your voltage is back up to a reasonable level is all.

My new R1S (VIN 117XX, not sure when made but Monroney sticker and Certificate of Origin dated 6/2/23) has the 12v battery + capacitor setup. I learned this yesterday morning when I got a call from the detailer who is wrapping the car with PPF. The car was unresponsive so he jump-started it and like OP, learned that it had a different 12v battery configuration from other Rivians he has worked on.

It took several jump-starts to get it to the point where he could not just open doors but also the charge port door. He then plugged in the charger and the car recognizes it's plugged in, but won't charge. Meanwhile my app is showing 61% battery (I dropped it off last Wednesday at 62%) but the car shows 0% and won't drive. They finished up the work today - I want to get my car back and they want to free up space in their shop.

This has been extremely frustrating being 40 minutes away from the car, and having to communicate with both Rivian Service and the detailer. I have spoken with Service at least six times in the past two days, and they once called the detailer, but until this evening the phone Service people were unable to get any kind of response from the local Service Center. (Interestingly, both Service people to whom I explained about the detailer's battery + capacitor finding - I hadn't yet read this thread - said they had never heard of this!).

Finally late today they connected with the Service Center and came up with a plan, which a mobile service tech will try to execute tomorrow. Their theory is that the detailer left a seat belt buckled overnight (or even over the weekend), which caused the car to stay awake or maybe even continue to run the AC, which then drained the battery. I said that if the 12v battery drains it should be replenished from the main pack. He said maybe the main pack was also run down. I am incredulous that any systems remaining on - even all weekend - could consume an amount of energy that would otherwise move the car 190 miles at highway speeds. Could that be the case?

I appreciate any thoughts on what's going on here. I'm coming from 10 years of Tesla ownership - one of each except the Roadster - and find it hard to believe that the car could waste so much energy without warning via the app. Tesla's app warns me when the AC is left on too long, windows are left open, or the car is left unlocked. If Rivian's doesn't do those things, it should. And all this happens because a belt is left buckled?

Thanks in advance.

If they are the same "engineers" who designed the completely asinine dual 12V battery system that no other manufacturer in the world uses (for good reason), has caused tons of issues, bricked many vehicles at Rivian's expense causing Rivian to abandon their wonderful design just a year into production.. then they should be hanging their heads, not shaking them!

I don’t know how you can make those statements without knowing why they designed it with dual 12 V. batteries.

As for “no other manufacturer in the world” using that design I remember seeing ICE vehicles with dual 12 V. batteries as far back as the ‘70s. You can still see them in today’s vehicles.

So tell me, what are the “(for good reason)” reasons.

Gotta use the 12v tap in the hitch compartment (small circle plug). IIRC, you need a 12v charger that can do at least 30A continuous before it will wake up. You can't plug in a 240v charger and expect it to work until the 12v system is back up.

Thanks, but they did jump start the 12v several times. That’s how they discovered the capacitor. But even once the car has come back to life, it is not fully there. It won’t drive, it won’t take a charge, and he said while it released the rear hatch, the hatch wouldn’t lift and open. Perhaps the 12v is just too far gone?

Assuming it was "user error" as opposed to a failure, Rivian should not allow this to happen. There should be some programmed logic that if the vehicle is parked, not in Camp Mode, there are no user inputs (no touches to the screen, no steering wheel or pedal motion, etc.) for a certain amount of time - let's say 90 minutes - then it should assume there is no one in the vehicle, sound a warning and prompt on the screen "Are you there??" If that question is not answered, they shoud power down the vehicle to prevent killing the batteries.

That damned seatbelt issue again. I noticed this issue on mine when I left a dog harness (one like this:

)

plugged into the passenger seat, and the car stayed awake all night long. ????

Since then have been hyper-vigilant whenever taking the dog out. Even short trips to the vet, make sure that thing is unplugged. The way it was explained to me was "what if a passenger is sitting in there and needs the AC?"... But what a dumb "feature", IMHO.

I've asked this before and never got an answer, so will ask again. Keep in mind, I don't have kids, will never have kids, and have never installed a child car seat. But could someone who's installed a car seat in their Rivian explain how they're not having constant battery drain all the time? Or do car seats not connect to the buckle? ?‍

My 12V died (about a week ago, I wrote a post about it), and I have no idea why. No kids, no dog, no one else has been in the truck. I do have an iphone charger plugged in, because the pad doesn't work, but nothing was plugged in when it died. Its taking Rivian almost 3 weeks to get to me for service.

Car seats do not attach to the buckle. They attach to dedicated, industry standard "anchors" made specifically for the purpose.

I thought Rivian was moving disabled vehicles to top of their priority for repairs.....maybe 3 weeks now is top priority best they can do.....which sucks...

Got the same harness plugged into my second row middle seat. Luckily no issue doing that.

So tell me, what are the “(for good reason)” reasons.

FWIW.. Rivian has already abandoned the troublesome dual 12V battery system due to it causing so many issues. They now use a single 12 volt battery like all other current vehicle manufacturers. In place of the 2nd 12 volt battery, they now use a large stiffening capacitor to handle large short duration start-up loads.

You do not want to leave it plugged in when not in use or the vehicle will never sleep.

Sometimes. But often you do use the seat belt.

For example, Rivian's middle seat doesn't have any latch anchor points. So if you're putting a kid there, you're going to be using the seat belt.

Also, latch anchor points have a weight limit. If the child + seat is too heavy, you have to use the seat belt to secure the car seat.

I've asked this before and never got an answer, so will ask again. Keep in mind, I don't have kids, will never have kids, and have never installed a child car seat. But could someone who's installed a car seat in their Rivian explain how they're not having constant battery drain all the time? Or do car seats not connect to the buckle? ?‍

Two of my three children are in car seats that are secured via seat belt rather than latch. I have never noticed the AC running when it shouldn't. And according to my app, the car is often asleep when I check on it.

Perhaps you're doing this in the front seat? Carseats don't go in the front. Ever. Second/third row only. Not just because adults would rather be in the front seat - it isn't safe to put kids in the front.

You do not want to leave it plugged in when not in use or the vehicle will never sleep.

My R1S sleeps fine with all of the 2nd row buckles plugged in (securing carseats).
