Rivian Assistant Improvements

Messaging and Calling

  • Uses an updated search hierarchy to identify the contact you are trying to reach by first searching your Favorites, then your Recents, and finally your main contact list.
  • Better recognize harder-to-spell names, nicknames, or slightly mispronounced names.
  • Automatically defaults to mobile numbers when calling a contact and uses natural language (like "Work" or "Home") when it asks you to confirm which number to dial.
  • Allows you to ask for information about a contact without automatically starting a call by saying something like, "Hey, Rivian, what number do I have for Mom?"

Conversations

  • When you dictate a text message, Rivian Assistant now automatically adds punctuation for you.
  • We've tuned the "Hey, Rivian" model to be more responsive, reducing the number of times you need to repeat yourself.
  • Rivian Assistant now has a better understanding of the hardware associated with your vehicle. For example, if you're in an R1T, it knows the vehicle doesn't have a powered liftgate.
  • If the connection drops while Rivian Assistant is processing your request, it now lets you know instead of staying silent.

Navigation

  • Rivian Assistant is now aware of routes visible on your screen before you start navigation, allowing you to ask for charging information or trip details for a route preview.
  • Rivian Assistant is now better at finding points of interest (POIs) and recalling recent destinations.
  • Updating a saved location (like Work) via voice no longer accidentally resets your charging filters.
  • We fixed an issue that caused every stop on a long trip to show the same arrival time.

Climate and Comfort

  • If cabin climate is off and you ask Rivian Assistant to set a temperature, it now restores your previous fan settings instead of defaulting to the lowest speed.
  • If you issue a vague climate request, like, "Hey, Rivian, make it warmer," Rivian Assistant now has a more sensible starting point for how much to increase the temperature, rather than just guessing.
  • We fixed several logic issues to ensure Rivian Assistant heats the exact seat you requested every time.

Calendar

  • If you have certain events hidden on your personal calendar, Rivian Assistant now honors those settings and won't display or read them out loud in the vehicle.
  • Rivian Assistant now anchors correctly to your local time and day when you ask a question like, "What's on my schedule this Friday?" or "What's happening tomorrow?"
  • Rivian Assistant now uses the correct past, present, and future tenses when describing your events, making the conversation feel more natural.

Cabin

  • Based on community feedback, we've reduced the volume of the chimes when using Rivian Assistant.

Under the Hood

  • Availability of Rivian Assistant is now based strictly on your vehicle language settings, regardless of your geographic region. If your vehicle language is set to English, Rivian Assistant is available.
  • We added smarter logic for how Rivian Assistant connects to the cloud, making it more resilient in areas with spotty cellular service.
  • If the vehicle temporarily loses its location, Rivian Assistant is now much better at providing helpful weather information without getting confused.
  • We fixed spacing issues in the messaging interface and ensured that long titles in the Owner's Guide wrap properly on the screen.
  • Rivian Assistant Memory (information Rivian Assistant learns to help you better) is protected by per-user encryption keys.
  • Rivian Assistant now automatically clears chat history and the visual panel whenever you switch driver profiles, ensuring conversations are yours alone.
  • We fixed dozens of issues and made various performance improvements behind the scenes.

NOTE

In order to get the most out of your experience with your Rivian Assistant, enable Rivian Assistant Memory in the Rivian mobile app version 3.12 or later. Choose Account > Rivian Intelligence > Memory and turn it on.

Additional Improvements

Profile Authentication

  • Fixed an issue that allowed a garage to be accessed and opened despite the profile being locked.
  • Fixed an issue that locked the profile when Stay off was selected while Camp courtesy was active.
  • Fixed an issue that prevented the PIN entry screen from appearing when attempting to switch profiles if the PIN screen had previously been canceled.
  • After a PIN is successfully entered to unlock a driver profile, the Navigation app now opens on the center display by default.
  • To help improve driving with the flow of traffic during Universal Hands-Free, Highway Assist, and Adaptive Cruise Control, we reduced the minimum speed to 5 mph (8km/h).
  • Fixed an issue that caused certain Launch Mode visual elements to overlap on the center display.
  • Fixed an issue that caused the garage door pairing menu to appear on top of the reverse camera screen if you shifted into R (Reverse) while setting up a new garage door opener.
  • Fixed an issue with Drive Modes app flashing black when you made changes.
  • Fixed a rare issue that caused some privacy settings to randomly toggle on or off, impacting location and Autonomy features. Please double-check your privacy settings after the update.

    • don’t understand the use of that expression here.. what long-perfected fundamentals are being stupidly redefined here? or do u just mean these are stupid things to spend time on vs other more important features?

    • ^This. I’m shocked to see it isn’t listed. I reported it a week ago, and I’m sure I wasn’t the first. It’s actually quite the dangerous bug when it system faults suddenly in the middle of a drive, without maintaining speed or enabling adaptive cruise instead.

      • Brand new R1S on first trip – constantly shutting down after about 20 minutes. I am hoping this fixed it

  1. On a side note, 12v battery replacement for r1t gen1 cost me 1600 so far [ 4+ years] .. . 800 each visit… so owners be aware the cost of ownership both r1t and r2 is high

      • what is the average time between “public release” and when the majority of people actually see an update? very frustrating reading about updates that are “rolling out” but then randomly don’t surface for days. I still have 2026.15.0 as up-to-date system for my gen1 today – 4 days after rollout. can’t think of another industry example of this and it’s a shame they can’t live up to modern software update expectation in the market, ie once an update is available (to any public user), it is available (within at least a few hours of initial rollout, not days) to all.

        • Staged rolling releases are done for many reasons and are very common in software development. Tesla does the exact same thing, as does Microsoft, as does Google for example. Sometimes the rollout is also paused due to an issue detected in the pilot group, which then turns into another fix and rollout. I can also imagine they want zero bad press during the R2 launch, so risk taking is at a minimum. I’m also on 2026.15.0–it will come when it comes.

  2. I am a new Rivian owner and very much appreciate all the helpful insights and advice.
    This is a very different vehicle ownership experience for sure but so far, really enjoying it. Keep up the great work!
