Car Firmware Changelog
2026.38 2 releases
2026.38.3
Tesla firmware 2026.38.3 began rolling out on 6 October 2026 at 0.1% of the fleet. Halloween Mode is the only genuinely new entry in its seven-item release note: Set Arrival Energy shipped in August with 2026.26, and Visual Updates, Supercharger Site Maps and Dynamic Headlight Leveling all arrived with 2026.38 on 29 September.
2026.38
Tesla started rolling out firmware 2026.38 on 29 September 2026, a new branch that skips five branch numbers past the current 2026.32. Only one entry is unambiguously new: Visual Updates, giving the centre display higher quality images of the car and an enhanced park scene. The Supercharger Site Maps entry is the feature's first appearance in a vehicle release note, but Site Maps have been in the car since the 2025 Holiday Update, still require an AMD Ryzen computer, and still cover only two European sites. Wheel Selection and Apple Music are carried forward from earlier branches. At 0.4% of the tracked fleet, early installs skew towards Europe on Model 3, Model Y and legacy Model X, though the sample is too small to call a pattern.
2026.32 2 releases
2026.32.7
Firmware 2026.32.7 reached customer cars on 23 September 2026 with release notes identical to 2026.32.3. The branch's real addition — a network-level ad blocker in the car browser, worth most on older Intel MCU2 units — has never been documented. The 2026.32 branch now covers about 46% of the tracked fleet.
2026.32.3
Firmware 2026.32.3 opened Tesla's 2026.32 branch on 9 September 2026 with just four release-note entries for Model 3 and Model Y: a new Wheel Selection option, a reprinted Apple Music entry, security fixes, and the remedy for EU Recall 2026_103555 on pole side impact. There is no FSD section at all — that work stays on 2026.27.x — and the build sits at 0.4% to 0.8% of the tracked fleet against 2026.26's 79.5%.
2026.27 2 releases
2026.27.200
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.
2026.27
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.
2026.14 3 releases
2026.14.6

2026.14.6

2026.14.3
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.
