Any Battery Degradation in your Rivian yet?

Service menu. I haven't tried accessing since updating from 2024.03, but supposedly it's hidden now.

Is that something we can do? Or required some kind of password?

I’m sure it’s been posted, but having trouble finding it, so here’s the steps:

Turn on service mode from your settings menu (I think in the ‘system’ area). Tap top menu bar 5 times, swipe up on app launcher to find the RiDE icon, tap 5 times on the Thomas Edison quote, then enter code 33748.

There is a BMS section that should give you the SOH (state of health) of your battery among other things.

Used to look like this

Now it looks like this

Thanks. What am I looking for to see the battery degradation percentage?

We can't see it anymore. SoH (State of Health) used to be really visible in the older version

Wow...considering Tesla had a tweet the other day saying only 12% degradation after 200k miles...that seems high.

Ha, try 30% on my Model S. Total BS.

Then all you all complained when you didn't understand the number. And now we don't have it.

What year of S and which config and mileage? If it truly has 20% or more within 8 years/ 100K miles or > 15% within the bumper to bumper warranty period, that's a new pack installed under warranty.

Tesla batteries settle or break in over time as well las the estimated range adjusting based on long-term driving habits. Even though Tesla is vague on that and many fan-boys claim that isn't the case, I've been a Tesla owner for 8-1/2 years with over 180K miles driven between my wife and I and can confirm that's exactly what happens.

Have you had the battery serviced and profiled with full diagnostics?

Don't blame this guy, I understand SoH curves, I was happy with my 94% @ 44k miles

I'm not convinced it meant what people thought it did. What my pack BMS reports and what the SOH reports don't coincide.

4 times with the full diagnostics. I have a bad brick in module 9 thanks to my canbus sleuthing. But it was "within normal operation". The warranty for my 2016 was unlimited miles/8 years. But there was no capacity clause, just failure. You may want to read the fine print again. What's funny is that it reads 70-71kwh of nominal energy, but you can't extract more than 60kwh. Once that brick drops below a certain voltage, the whole module "disappears" from the capacity calculation. Original capacity for the 90-A packs was somewhere between 84-86kwh. All very frustrating. Anyone who is going by the dash number on their Tesla is living in ignorant bliss. The only sure fire way to tell the battery health is to drive from 100% to 0% at EPA consumption (290 Watts/mile on mine) with no HVAC, and canbus monitoring. Btw, the last 4kwh on your battery is added to the range at 100% but slowly taken away until 0%. So the car is actually lying to you anyway on how far you can drive.

Rivian has since upped the available kWh percentage of the pack.
The physical pack is 141kWh, rated at 135kWh.

Large pack is rated at 131 kWh (according to Rivian).

Good link/source.

Here is my comparison Gsheet that I've spent a fair amount of time on.

15k miles, just charged to 90% and calculate full battery health on large battery. Put over 102kw in going from 15%->90%. Range still estimating like new.
I mostly fast charge from 20% to 70%. Occasionally at home. Only a handful of times to 95%+
