Rivian halted the rollout of its 2026.07 software update on Saturday after the build triggered phone key and key fob failures on Gen 1 vehicles and wiped owner data including elevation records, saved radio stations, and contact addresses.
Deployment data from the third-party tracking platform Rivian Roamer shows the update went from 2,187 new installs on Thursday to 3,555 on Friday before dropping to just four on Saturday — a near-complete halt.
The fleet currently shows 2,551 out of 5,712 monitored vehicles with the update installed, down from a peak of approximately 70% before Rivian stopped pushing the build.
Rivian Roamer‘s fleet distribution data as of Saturday showed the fleet split roughly in half: 47% on 2026.07 and 53% still on the previous build, 2026.03 — meaning more than half the tracked fleet will remain on the older software until a patched version is released.
The 2026.07 build arrived after a nearly seven-week gap from the previous update, 2026.03, which Rivian released on February 19 under the name “Cold Snap.”
The update was one of the company’s largest in months, introducing Universal Hands-Free driver assistance on over 3.5 million miles of North American roads, an Apple Watch companion app, Rivian Digital Key with UWB support, the RAD Tuner custom drive mode for Quad-Motor vehicles, an Unreal Engine 5.5 upgrade for the vehicle’s 3D renderings, and the Kick Turn low-speed rotation feature.
The long wait made owners particularly eager for the 2026.07 version.
Rivian has not issued an official public statement as of early Sunday.
A patch is expected early next week, consistent with the company’s pattern of avoiding weekend software pushes.
What Went Wrong
Owner reports across Reddit, Rivian Forums, and X point to two primary categories of failure.
The most severe involves phone key and key fob functionality breaking on Gen 1 R1T and R1S vehicles.
One owner described the situation on Reddit: “2026.07.0 broke all phone keys and key fob… Only the key cards still work… Service appointment over a month out.”
Multiple owners confirmed the issue in the thread, reporting that re-adding keys in the app failed — with setup buttons greyed out — and that some vehicles would not authorise drive even with the fob present.
Only the NFC-based key cards continued to function.
The second major issue involves widespread data resets.
A number of things have been cleared out for many owners, including elevation min/max records, saved radio stations, and saved contact addresses.
The elevation wipe was particularly frustrating for Rivian’s adventure-oriented customer base — owners lost tracked records of their highest and lowest points driven. “My elevation stats were wiped out… Bad Water Basin at -274 and Coyote Flats at 10,091,” one owner wrote on the Rivian Forums.
Contact addresses were removed from navigation, eliminating the full address display and “Go” button. Saved radio stations were cleared. Owners also reported randomised settings changes affecting door unlock behaviour, interior lighting, and garage door opener functionality, as well as HD Radio loss.
Several owners also reported that the update simply vanished from their vehicle or app menu after it had been offered or downloaded, suggesting Rivian was actively pulling it from the queue.
The 2026.07 Upgrade
The 2026.07 build, first noticed on April 3 and publicly released on April 9, was primarily a stability and refinement release with no major new features.
For all vehicles, it included improved infotainment stability and faster app launch times, better Wi-Fi, cellular, and app connectivity, Apple Music Dolby Audio support and a new streaming quality setting to reduce buffering, and a fix that links rear defrost activation to the front wiper heating element.
Gen 1 vehicles received 12V battery capacity management improvements.
Gen 2-exclusive updates included a fix for Lane Change on Command being immediately rejected after a previous lane change, reduced steering wheel vibrations at highway speeds, improved range estimate consistency, better 12V diagnostics, and a fix for a rare charge port door issue after water ingress.
Not the First Time
The pull comes as Rivian prepares for the launch of its R2 mass-market SUV, which has reportedly begun limited employee deliveries.
Rivian‘s software chief Wassym Bensaid also serves as co-CEO of RV Tech, the 50/50 joint venture between Rivian and the Volkswagen Group that is developing the next-generation software-defined vehicle architecture for VW brands in the Western Hemisphere.
The joint venture completed winter testing of its production-intent zonal architecture on March 27, validating the platform across prototype vehicles from Volkswagen, Audi, and Scout Motors in Phoenix and Arjeplog, Sweden.
VW engineers are expected to begin embedding at RV Tech’s Palo Alto office in May to deepen their knowledge of the architecture.
What’s Still Missing
As EV reported when the 2026.07 release notes first surfaced, the update does not include the Rivian Assistant — the AI-powered voice interface the company announced at its Autonomy & AI Day on December 11 and promised for “early 2026.”
Chief Software Officer Bensaid said at the event that it would launch on every existing Rivian vehicle, not just the second-generation R1 models.
The assistant, the product of a two-year internal development effort, is designed to handle climate controls and other infotainment tasks while connecting vehicle systems with third-party apps through an agentic framework built by Rivian’s engineers.
Rivian said the system would be augmented by frontier large language models including Google Vertex AI and Gemini. An offline-capable version is planned for the R2. As of the 2026.07 release notes, the feature has not shipped — four months after the commitment.
Text messaging integration — consistently cited as the top community request on Rivian’s forums — is also absent. Apple CarPlay and Android Auto remain unavailable on R1 models.
Version 2026.07 is only the second public software release of 2026, following 2026.03 on February 19.
The roughly seven-week gap between updates is slower than the near-monthly pace Rivian maintained in 2025, when the company pushed 11 over-the-air updates.
