Tesla Software Update Tracker
Tesla Software Update Tracker
Verified Tesla software versions, rollout status, supported vehicles and owner-facing changes.
Tracker status: Active. Latest verified check: September 14, 2026 at 4:06 AM PDT. Company statements are separated from specialist fleet observations, and software availability remains dependent on vehicle, hardware, region and staged rollout.
2026.32.3: staged rollout expanded
Evidence status: Reported · independent specialist rollout observations. At the September 14 check, TeslaFi displayed 1410 sampled vehicles on 2026.32.3, including 292 installs during its current day. Teslascope separately displayed 22 September 14 observations. No readable Tesla first-party version record was available to this workflow, so this remains a tracker update rather than a Tesla-confirmed release or feature announcement.

2026.32.3 Reported · staged rollout expanded |
TeslaFi's live table showed 1410 sampled vehicles and 292 current-day installs. Teslascope showed 22 observations dated September 14. These services use different samples and counting methods; their figures are not combined and are not Tesla-wide fleet counts. | The observations support continued rollout activity across several regions. Specialist pages associate the branch with software and interface changes, but this tracker does not establish safety performance, recall scope, universal hardware eligibility, availability for a specific VIN, or a completed rollout without readable Tesla primary documentation. | TeslaFi: live firmware trackerTeslascope: 2026.32.3 rollout pageNot a Tesla App: mirrored 2026.32.3 notes |
Owner note: Check the Software screen and release notes displayed in your own car. Do not infer safety, availability, hardware support, recall scope or behavior changes from a tracker entry; driver-assistance use remains actively supervised.
2026.27.6: staged rollout expanded
Evidence status: Reported · independent specialist rollout observations. At the September 14 check, TeslaFi displayed 491 sampled vehicles on 2026.27.6, including 76 installs during its current day. Teslascope separately displayed 102 September 14 observations. No readable Tesla first-party version record was available to this workflow, so this remains a tracker update rather than a Tesla-confirmed release announcement.

2026.27.6 Reported · staged rollout expanded |
TeslaFi's live table showed 491 sampled vehicles and 76 current-day installs. Teslascope showed 102 observations dated September 14. These services use different samples and counting methods; their figures are not combined and are not Tesla-wide fleet counts. | The observations support continued North American rollout activity. Specialist pages associate the branch with FSD (Supervised) 14.3.9 for AI4 vehicles and 14.2 Lite for HW3 vehicles, but this tracker does not confirm safety performance, universal hardware eligibility, availability for a specific VIN, or a completed rollout without readable Tesla primary documentation. | TeslaFi: live firmware trackerTeslascope: 2026.27.6 rollout pageNot a Tesla App: mirrored 2026.27.6 notes |
Owner note: Do not assume this version is available for your vehicle. Wait for the Tesla app or in-car Software screen, review the release notes shown on the vehicle, and keep all driver-assistance use actively supervised.
Summer Release voice stack: Grok Think Fast 2.0
Evidence status: Company-reported model identification · official SpaceXAI model documentation. Tesla said its 2026 Summer Release uses Grok Think Fast 2.0. SpaceXAI's official model page and developer release notes document the named voice model. The statement does not establish universal availability across every Tesla, market, language or software branch.
| Checked | Status | What it means | Evidence |
|---|---|---|---|
|
In-car Grok voice model Company-reported |
Tesla identified Grok Think Fast 2.0 as the model used by the 2026 Summer Release. This is a company statement about the release's voice stack, not an independent vehicle-by-vehicle deployment measurement. | The named model is documented by SpaceXAI as a speech-to-speech voice model. SpaceXAI's developer notes show the versioned model and the separate grok-voice-latest API alias, but that API documentation does not prove that the vehicle build uses the public API alias or identical server-side routing. |

Owner availability Verify in vehicle |
Tesla's one-line model statement does not list supported countries, languages, vehicles, hardware generations or a complete staged-rollout schedule. | Owners should confirm the installed software version and the Grok interface shown in their own vehicle. Model identification does not establish universal availability or guarantee the same controls and voice behavior on every car. | Tesla North: same-window report and availability boundary |
Owner note: Treat Think Fast 2.0 as Tesla's reported model for the Summer Release, not as proof that every eligible vehicle has received it. Check the Tesla app and the vehicle's Software screen before relying on a reported feature.
China FSD status: Shanghai data-center denial
Evidence status: Company-reported denial · multiple direct newsroom responses. Tesla China told The Paper and Southern Metropolis Daily that its Shanghai data center is operating normally, driver-assistance recruiting is accelerating and it reported the shutdown rumor to police. These are attributed company statements, not an independent inspection of the facility.
| Checked | Status | What it means | Evidence |

Shanghai data center Company-reported |
Tesla China denied reports that the center had been emptied or the related team withdrawn. Two independent Chinese newsrooms published direct responses from the company on August 26. | The denial is evidence of Tesla's stated position. It does not independently prove staffing levels, data-center utilization or a launch timetable. | The Paper: direct Tesla China responseSouthern Metropolis Daily: direct Tesla China response |
|
China customer availability No new rollout |
Tesla's China safety page says driver-assistance availability can require explicit local approval, lists the markets where the feature has launched and says it cannot provide an exact timetable. Mainland China is not listed among those launched markets. | No China rollout date was announced. A data-center operating statement does not confirm full FSD availability, a subscription launch or regulatory approval for Chinese owners. | Tesla China: driver-assistance safety and approval guidance |
Owner note: Treat the shutdown claim as an unverified rumor that Tesla disputes. Check the vehicle, Tesla app and current official China product pages for features actually enabled on a specific car; do not infer availability from the denial alone.
Latest rollout observations
Evidence status: Reported · specialist fleet observations. Tesla had not published matching first-party release notes when this tracker was checked. Rollouts are staged, so availability varies by vehicle, hardware, region and branch.

2026.21.6 Reported |
At 5:15 p.m. PDT on August 14, Teslascope reported about 6,160 additional vehicles receiving this branch. Now Rolling Out called it the eighth observed wave. | The two specialist trackers associate the branch with FSD (Supervised) 14.3.7 on eligible AI4 vehicles and FSD 14.1 Lite on eligible HW3 vehicles. These version mappings and the wave count remain specialist observations, not Tesla-confirmed release notes. | Teslascope fleet observationNow Rolling Out wave observation |

2026.26.6.1 Reported |
At 7:25 p.m. PDT on August 14, Teslascope reported about 3,520 additional vehicles receiving this branch. Now Rolling Out called it the fourth observed wave. | Now Rolling Out describes the branch as a minor-fix build carrying the 2026 Summer Update. No matching Tesla primary release note was found during this check, so the feature scope is not promoted to Confirmed. | Teslascope fleet observationNow Rolling Out wave observation |
Owner note: Do not assume a version is available for a specific car until it appears in the vehicle or Tesla app. Keep the vehicle on Wi-Fi and review the in-car release notes before installation.
