Update September 25, 2025: Rivian has confirmed the details of software update 2025.34 outlined below. However, we still do not have a concrete timeline for when the update will roll out to current R1S and R1T owners.
Like most software-defined vehicles, Rivian models like the R1S and R1T receive periodic updates over-the-air (OTA). As a Rivian owner and an enthusiast, software updates are often exciting news to report on, as they usually result in new features or abilities to existing technology or enable various efficiencies (and bug fixes fixes, of course).

In late May, RivianTrackr shared that software update 2025.18 was rolling out internally before launching wide to Rivian owners, and it was one of the more robust rollouts we had seen for a while.
