Rivian's 2026.07 software update quietly improved DC fast charging in a way owners can actually feel. I pulled my 2025 R1T Tri-Motor Max into an IONNA Rechargery in Orlando today and watched it hold above 200 kW from 14% all the way into the low 50s, going from 14 to 70% in 25 minutes flat. Rivian has since confirmed thermal adjustments were made, with more on the way.

Rivian is partnering with EnergyHub to expand access to utility managed charging programs across North America, allowing owners to save on charging costs while helping stabilize the electric grid through smarter, automated charging.

A Gen 2 Rivian R1S Dual Standard owner equipped with the LFP battery and 20" AllsSeason wheels, rated at 258 miles EPA, shared real world winter data showing dramatically lower range. With efficiency of 1.35 mi/kWh and just 115 miles displayed at 85%, the numbers raise fresh questions about ongoing calibration and cold weather impact.

Months after Rivian first acknowledged an LFP battery range calibration issue affecting Gen 2 R1 Dual Standard vehicles, owners are once again receiving guidance from Rivian Engineering. Despite running the latest software, the continued outreach suggests the issue is still being actively mitigated rather than fully resolved.

Rivian finally sent an email today about the Dual Standard LFP range estimation issue, and it confirms what a lot of owners have been dealing with quietly for weeks. The message explains that a software calibration problem can cause the range estimate to get less accurate as the state of charge drops, especially below 20%. The fix is part of…
