Tesla Rolls Out 2026.27.10 Update With FSD 14.3.10

Tesla has begun pushing a new software update, version 2026.27.10, to vehicles in its fleet, according to release notes tracked by Not a Tesla App. The update includes FSD 14.3.10, the latest build in Tesla's Full Self-Driving 14.3 software branch.

What We Know So Far

The release was flagged through Tesla's official in-car release notes, which the outlet Not a Tesla App regularly monitors and publishes as new software versions roll out to owners. As with previous incremental updates in the 2026.27 and FSD 14.3 series, this build is part of Tesla's ongoing cadence of over-the-air software refinements delivered directly to compatible vehicles.

Tesla typically distributes these updates in staged waves, meaning not all eligible vehicles receive 2026.27.10 and FSD 14.3.10 simultaneously. Owners are generally notified through their vehicle's touchscreen or the Tesla mobile app once the update is available for download and installation.

Why It Matters

Software updates like this one are central to Tesla's approach of continuously improving vehicle functionality after purchase, spanning everything from user interface tweaks to changes in driver-assistance behavior under the FSD umbrella. Because detailed line-by-line change logs are published by Tesla directly to vehicles rather than through a public press release, outlets such as Not a Tesla App play a key role in surfacing this information for the wider Tesla community and prospective buyers tracking the pace of FSD development.

Tesla has not issued a separate public statement beyond the in-car release notes referenced in this report. As more details or owner feedback on 2026.27.10 and FSD 14.3.10 emerge, further reporting is expected to clarify the scope of changes included in this release.
