Review – Rivian 2025.38 Update Brings Climate Hold, IONNA Support, and Big Charging Upgrades

Rivian’s rolling out software update 2025.38, and it’s packed with useful quality-of-life upgrades that make daily driving just a little smoother. I spent some time testing everything that’s new in this release, including Climate Hold, auto cabin ventilation, Plug & Charge support for IONNA and Electrify America, and a few hidden tweaks Rivian didn’t exactly highlight. Plus included in this release is all the Halloween goodies which you can check out in my other video.

Check out my full hands-on review video below where I walk through each feature, show how they work in real life, and talk about what Rivian might be planning next.
