Jose Castillo is the founder and editor of RivianTrackr, an independent publication he started to cover Rivian from an owner's point of view. He has followed the company since early in its consumer history and has owned and leased several Rivians over the years, including multiple R1T and R1S vehicles. Today he drives an R1S and an R2 in Florida and uses Universal Hands-Free for his daily driving.

Most of his coverage comes from firsthand access rather than press releases. He was at the R2 First Drive in Park City for hands-on time with the production R2 and RivianOS 2.0, and he reported from SXSW when Rivian revealed the full R2 lineup. He has spoken directly with Rivian leaders like Wassym Bensaid and James Philbin about where the company is taking its software and autonomy work.

Before RivianTrackr, Jose worked at Apple as a software developer, which is part of why he follows Rivian's software and autonomy side as closely as he does. He has also helped more than 400 people order their own Rivians through the site. The whole thing stays independent, written by an owner for other owners.

Your Old Charging Adapter Could Fail on the Rivian R2

Tom Moloughney melted a pin on an older Tesla adapter while charge testing the R2, and the reason is the R2 itself. It pulls more current than almost anything else on the road, which means the adapter in your frunk may not be up to it.

R2 VIN Assignments Climb Into the 4100s as Deliveries Lag

A friend of the site had his R2 VIN assigned in the low 4100s, a sign Rivian keeps moving reservation holders forward. Deliveries still look slower than expected though, with plenty of R2 sitting in Normal and some owners left waiting on vague "final checks" while software update 2026.24 begins rolling out.
