Tesla's software deployment radar is expanding. Teslascope has detected version 2026.15.6 running on a 2023 Model X Plaid in Gyeonggi-do, South Korea — marking the first confirmed sighting of this build in the wild.
No official release notes have surfaced for 2026.15.6 yet, which puts it in familiar territory — Tesla routinely pushes minor point releases ahead of any public changelog. To put the version in context, the broader 2026.14.x branch has been the dominant global rollout through early June, with 2026.14.6.6 (bundled with FSD Supervised v14.3.3) actively deploying to over 13% of the tracked fleet according to Teslascope data. The jump to a 2026.15.x branch suggests Tesla is seeding a new minor release line, likely carrying incremental fixes or regional adjustments rather than a headline feature drop.
User reports associated with the 2026.15 line mention lingering rain-sensing wiper inconsistencies and occasional climate fan speed sync issues — both recurring complaints across recent builds. Whether 2026.15.6 addresses either remains unconfirmed until more vehicles check in and owners share notes. Keep an eye on all software updates here as rollout data fills in over the coming days.
