Car Firmware Changelog

Tesla firmware 2026.27.200, released 1 September 2026, is the first build in the 2026.27 branch to carry a recall notice: the remedy for EU Recall Submission 2026_103555, restoring compliance with UNECE Regulation No. 135 on pole side impact, for Model 3 and Model Y. Every other release-note entry is carried forward from 2026.27.100.1 unchanged.

Firmware 2026.27.100.1 brings the 2026 Summer Update and FSD 14.2.2.6 to Hardware 4 cars on the FSD branch, starting in Europe — the first merge of Tesla's FSD and feature branches this cycle.

Tesla's 2026 Summer Update has landed as firmware 2026.26, released on 26 July 2026 and already superseded by a 2026.26.1 point release. The feature split follows infotainment silicon: Grok voice commands, Caraoke scoring and the new browser camera access need the AMD computer, while Preferred Routes and Supercharger-by-name search reach the whole fleet.

Tesla's 2026.20 firmware introduces Parental Controls that block the in-car Web Browser, Tesla Theater, and Tesla Arcade; AES-style Dashcam clip encryption keyed to the Tesla account; and integration of xAI's Grok assistant via the App Launcher. Rear-seat map interaction and customisable Pet Mode names round out the release.

Tesla started rolling out firmware 2026.14.6 on 12 May 2026. The release focuses on bug fixes and security improvements, with Tesla pushing some installs over cellular to speed deployment.

Tesla 2026.14.6 introduces a one-tap Self-Driving subscription app, Premium Immersive Sound, interactive rear-display navigation for passengers and expanded avatar customization on top of the carry-over 2026.14 Spring feature set.

Tesla's 2026.14.3 Spring Update entered its third deployment wave on 28 April 2026, bringing sharper Model 3 and Model Y visualizations, the new Creations app for sketches and Photobooth, 24-hour Dashcam clips, weather maps, and overnight automatic install scheduling.
