  1. Please Help, My R1S is Bleeding Kilowatts

    Y'all are too kind. I'm glad you're enjoying it – let's keep an eye on it. I'm happy to pull raw data if you need/want to nerd out over it at some point. You can always reach me directly at [email protected]. I respond to every email. I can also help provide data you can give to Rivian...
  2. Please Help, My R1S is Bleeding Kilowatts

    It should at least tell you if you're vehicle is sleeping or on the daily view.
  3. Please Help, My R1S is Bleeding Kilowatts

    Rivian tries really hard to abstract the complexities of EV ownership from people. But like you said, when things fail they have no UX escape hatch.
  4. Strange calibration issue on gen2 Max Pack - service has not seen this before

    The nominal gross capacity of a max pack is 150 kWh. There is the real possibility this is a bug in Rivians secret reservation they do. My Gen 1 large stops increasing range at 97%. it seems Rivian sets aside a buffer so that as a battery degrades it didn’t show in the range until a certain...
  5. Please Help, My R1S is Bleeding Kilowatts

    Keeping proximity unlocking on at home almost always is a source of drain.
  6. Please Help, My R1S is Bleeding Kilowatts

    This happened to me, my car was far enough away from "home" it was no longer "home" and gear guard was on all of the time.
  7. 2026 Gen 2 R1S battery capacity drop due to cold - what’s normal?

    I have tried to use ABRP so many times and find the UX incredibly confusing. I have three Rivians. Signed up, linked my account, selected my R1S and it goes "Cook, here's your R1T" with no obvious way to switch.
  8. Elevation Change? That's got to be a record of all time!

    I'm trying to be nice in case Rivian is looking. 👀
  9. Elevation Change? That's got to be a record of all time!

    Oh, I assumed so 😂 50% of Rivian Roamer's code is working around really bad data from Rivian
  10. Elevation Change? That's got to be a record of all time!

    I think someone air-shipped their Rivian. Looks like bad telemetry. I do have corruption detection, will look into this case.
  11. 2026 Gen 2 R1S battery capacity drop due to cold - what’s normal?

    Yeah capacity would affect total range but not efficiency. Unless Rivian is doing bad math with efficiency.
  12. 2026 Gen 2 R1S battery capacity drop due to cold - what’s normal?

    Carefully read the (i) helper next to battery capacity. This swings wildly (as seen in your graph). This is not an indication of actual battery capacity.
  13. Strange calibration issue on gen2 Max Pack - service has not seen this before

    Well, the reason it can trigger it is the way Rivian setup wheel/tire swaps. If you notice it has a very long reboot. It's because it's re-installing the software. I think they legit build the software when installing or something and bake the configuration of the vehicle into that build. Maybe...
  14. Strange calibration issue on gen2 Max Pack - service has not seen this before

    I think this actually may confirm my hypothesis. I've had a few support emails on RR from customers who had issues pop up after updates where a config was mis-flashed, or when changing wheel/tire combos (Which does the same thing). I'll send this along to someone at Rivian.
  15. Strange calibration issue on gen2 Max Pack - service has not seen this before

    You know what. I wonder if your vehicles were originally Large packs that had them swapped out. Or Large+ that had the cap removed. I have quite a few folks on Rivian Roamer that have Standard or Large pack vehicles that have a Max pack installed in them but software limited. This almost looks...
  16. Strange calibration issue on gen2 Max Pack - service has not seen this before

    Oh, I understand now. Yes – the data is there this is a display quirk. Many said for DCFC sessions they didn't want to see battery level and preferred to see the curve where the X axis was the charge % instead of time. Given your battery was pegged at 99% this creates a strange display issue...
  17. Strange calibration issue on gen2 Max Pack - service has not seen this before

    If anyone is willing or wants me to they can DM me link to their charging session and I can share the data in this thread. But looking at @kxev's session both the SOC and Range numbers stopped incrementing once they hit 99%.
