  1. Opinion on 20" tires for R1T

    I am struggling with this very same decision, but am hung between the Goodyear Territory that I am currently running and the Michelin Defender. Has anyone on here run both that could provide a comparison?? I have the Goodyear Territory and have been thrilled with them, but I am at about 20K...
  2. Recurring R1T 12V Failure — Rivian Refusing LV Battery Replacement Procedure (3 Attempts, No Escalation)

    I was written by Ohmmu customer service after an inquiry. They advised that they are releasing a sodium based battery and thus far, all of their testing shows compatibility with Rivian, even after the latest monitoring algorithm. They have equivalent or better charge/discharge cycles, perform...
  3. Comma AI/OpenPilot Update -- Watch it in Action on Gen1 Rivian (Video)

    I just switched to WMIv8. Between that and toggling the Longitudinal back on, Huge improvement. I am so happy to have regular performance back! Thanks to the Hive for all of the help and suggestions!
  4. Comma AI/OpenPilot Update -- Watch it in Action on Gen1 Rivian (Video)

    I had no idea this existed! What model are you running? I may have my settings off? Is this in the ā€œsettingsā€? I just looked around and did not see it thanks sir! May I ask what model you are using now? I suspect it is time to switch so I can get back to daily use habits You are correct...
  5. Comma AI/OpenPilot Update -- Watch it in Action on Gen1 Rivian (Video)

    I measured to center of the windshield. I have been using it for over a year and never had an issue until about 6 weeks ago. I thought it was a glitch when the updates switched to Firehose. I also noticed the 3 driving personalties are greyed out and the right knob has gone back to distance...
  6. Comma AI/OpenPilot Update -- Watch it in Action on Gen1 Rivian (Video)

    I have been using the Comma 3 on my launch edition R1T for some time and really enjoyed it. for the last many weeks, I have noticed it constantly stays to the right side of the lane. I have confirmed install location, recalibrated, reset the entire unit and reloaded sunnypilot. It still...
  7. Recurring R1T 12V Failure — Rivian Refusing LV Battery Replacement Procedure (3 Attempts, No Escalation)

    I have been told that I will be mandated to switch to OEM battery install at my expense. Many, many Ohmmu users have experienced exactly the same thing since the October update. No solution seems to be planned. They will swap them out at the service center on Jan 5th.
  8. Recurring R1T 12V Failure — Rivian Refusing LV Battery Replacement Procedure (3 Attempts, No Escalation)

    Thanks for weighing in! I am glad to know there are many of us in this boat, and I am hopeful for a long-term solution soon. I will keep you and all posted should I gain some resolve.
  9. Recurring R1T 12V Failure — Rivian Refusing LV Battery Replacement Procedure (3 Attempts, No Escalation)

    What? How is this comment even remotely helpful. I love when commenters such as you hop on and offer an opinion that adds nothing to the discussion. The fact that you could not be bothered to even read through the thread is pitiful. Try scrolling up buddy, read a little, then offer your...
  10. Recurring R1T 12V Failure — Rivian Refusing LV Battery Replacement Procedure (3 Attempts, No Escalation)

    I am not really even sure what an "AI Hallucination" is? I got this information from one of the many forums that I participate in and search as I may, I was not able to find which one. I copied and put the information in my apple notes as I was contemplating the 12 lithium iron phosphate, but...
  11. Recurring R1T 12V Failure — Rivian Refusing LV Battery Replacement Procedure (3 Attempts, No Escalation)

    That is actually the next step. I have heard from the number of forums I participate in that many who have these Ohmmu batteries have experienced the same as I have and all seem to have this occur after the October OTA. This points to a software issue and If I have to buy OEM to resolve, then...
  12. Recurring R1T 12V Failure — Rivian Refusing LV Battery Replacement Procedure (3 Attempts, No Escalation)

    That’s not accurate. Rivian is not refusing hardware support — they are refusing to complete the diagnostic sequence that determines whether the hardware is the issue. That obligation doesn’t disappear because a 12V battery is aftermarket, especially when the vehicle is out of 12V warranty...
  13. Recurring R1T 12V Failure — Rivian Refusing LV Battery Replacement Procedure (3 Attempts, No Escalation)

    No issue with the 12 volts charging. This all appears to be a false flag. I can monitor the batteries real time and confirm with a dashboard that they have not dipped below 13 volts. I typed all of the notes in at the Rivian service center for detail, but the invoice did not show that the...
  14. Recurring R1T 12V Failure — Rivian Refusing LV Battery Replacement Procedure (3 Attempts, No Escalation)

    I totally get the point about Rivian focusing on their own hardware — and I’m not asking them to fix an Ohmmu battery. I’m asking them to complete the diagnostic sequence that determines whether the battery is actually the cause in the first place. Right now, the truck clears the warning...
  15. Recurring R1T 12V Failure — Rivian Refusing LV Battery Replacement Procedure (3 Attempts, No Escalation)

    I understand the chemistry concern, but the behavior of the system doesn’t actually match a charge-curve mismatch. When a 12V battery truly conflicts with the expected chemistry or discharge profile, the system flags it immediately — during charging events, driving, or boot-up. It does not clear...
  16. Recurring R1T 12V Failure — Rivian Refusing LV Battery Replacement Procedure (3 Attempts, No Escalation)

    I’m not trying to gloss anything over – I mentioned the Ohmmu app simply because it’s the tool that reports voltage and balance data for those batteries, just like a multimeter or DMM does. Transparency isn’t an issue here. The real point is that the system behavior doesn’t match a...
  17. Recurring R1T 12V Failure — Rivian Refusing LV Battery Replacement Procedure (3 Attempts, No Escalation)

    What’s ā€˜Ranger’? Mobile service? Where are you getting the ā€˜full procedure’ steps from? This context will help us to help you advocate for yourself.
  18. Recurring R1T 12V Failure — Rivian Refusing LV Battery Replacement Procedure (3 Attempts, No Escalation)

    Thanks — and that’s exactly the issue I keep running into. It’s not that Rivian has no one capable of handling this, it’s that I can’t reach anyone at that level. Every contact point (app, chat, phone, and the service center itself) routes everything through front-line advisors who don’t have...
  19. Recurring R1T 12V Failure — Rivian Refusing LV Battery Replacement Procedure (3 Attempts, No Escalation)

    Sharing this for technical visibility because my 2022 R1T has developed a repeating 12-volt system failure, and after three attempts (Ranger + service center), Rivian still hasn’t performed the correct low-voltage initialization procedures. Symptom Pattern: ā€œReplace 12V Battery Systemā€...
  20. 12V Failure message-plugged in. Switch to Ohmmu Lithium or Stay with Rivian 12v??

    This was a huge concern I had, but the Ohmmu batteries have a feature that pre-heats the battery in cold temperatures during charging to avoid the issue. I am just not sure if this is through the BDU, nor how reliable that is?
