Teslascope has detected a new Tesla software version — 2026.14.300 — appearing on a 2026 model vehicle as a factory update. Unlike standard over-the-air rollouts, factory updates are pre-installed on vehicles before they leave the delivery center, meaning this one is exclusive to recently delivered cars rather than something existing owners will receive as a push.
The version sits within the broader 2026.14.x software branch, which has been one of Tesla's more feature-rich release families this year. According to teslascope.com, the update was first detected on June 24, 2026, and is currently rolling out. No dedicated release notes for 2026.14.300 have been published, which is typical for factory builds — Tesla doesn't issue changelogs for these the way it does for mainstream OTA updates.
For context, other versions in the 2026.14.x lineage have introduced automatic overnight software updates, the "Hey Grok" voice activation shortcut, a redesigned Self-Driving app with FSD (Supervised) v14.3.4, rear display maps for passengers, blind spot warning accent lights, and an enhanced Dashcam viewer. It's reasonable to expect 2026.14.300 carries these same foundations, built and validated specifically for vehicles rolling off the line right now.
If you're taking delivery of a new Tesla in the coming days or weeks, this is likely the software version you'll find waiting on the touchscreen. For existing owners, there's nothing to do here — factory updates don't push to vehicles already in the field. Keep an eye on all software updates as Tesla continues iterating through the 2026.14.x branch.
