π UPDATE β October 31, 2026
π Undocumented change spotted: Tesla's 2026.38.6 update quietly adds Latvian language support to the vehicle UI β a change not listed in any official release notes. The addition appears timed with Latvia's recent regulatory approval of FSD (Supervised), suggesting Tesla is preparing the market for a broader rollout. This follows a pattern Tesla has used in other newly approved regions, where UI localization lands in firmware just ahead of or alongside FSD activation.

π UPDATE β October 31, 2026
Tesla 2026.38.6 has expanded to a second rollout batch, now reaching approximately 7% of the fleet β up from the 238 installs tracked at initial publication. The update's changelog remains focused on security improvements, as do the intermediate 2026.38.3.1 and 2026.38.3.2 releases that preceded it. Notably, the broader 2026.38.3 branch introduced Halloween Mode for vehicles equipped with the AMD Ryzen infotainment chip β a spooky seasonal easter egg that lets owners spread some holiday fear from their touchscreen. If your car has the Ryzen hardware and you're on any 2026.38.3+ build, check your Toybox for the feature.
π UPDATE β October 30, 2026
Tesla has pushed a second wave of the 2026.38.6 firmware rollout as of this evening. According to @NowRollingOut, this wave specifically includes security improvements β confirming that 2026.38.6 carries more than just the previously noted changes. If you haven't received the update yet, now is a good time to check your Tesla app or tap Software β Check for Updates on your touchscreen, as the wider wave means more vehicles are being targeted.
π UPDATE β October 30, 2026
The rollout of both 2026.38.6 and its point release 2026.38.6.1 has accelerated significantly. According to Teslascope fleet data, 2026.38.6.1 pushed to approximately 3,850 additional vehicles in a single five-minute window around 10:00 PM UTC, while 2026.38.6 hit roughly 2,200 more vehicles forty minutes later β a strong signal that Tesla is ramping both builds in parallel. Install counts have grown well beyond the 238 tracked at the time of our original report, suggesting a broad fleet-wide wave is now underway. If you haven't received a notification yet, check Controls β Software and tap Check for Updates.
π UPDATE β October 29, 2026
Tesla 2026.38.6 is now confirmed in its first batch rollout, reaching approximately 2% of the fleet. The update's primary addition is Security Improvements, consistent with the intermediate 2026.38.3.1 and 2026.38.3.2 releases that preceded it. Notably, the changelog traces back to 2026.38.3, which introduced Halloween Mode β a seasonal feature exclusive to vehicles equipped with AMD Ryzen processors. If you're on an older AMD Ryzen-equipped Tesla and haven't seen Halloween Mode yet, this rollout may finally bring it your way. The broader 2026.38.x branch appears focused on incremental security hardening alongside this limited hardware-specific feature.
π UPDATE β October 29, 2026
Tesla 2026.38.6 has now been spotted in Europe, with @teslascope confirming a deployment to a 2023 Model X AWD in Aargau, Switzerland. This marks the update's first verified appearance outside North America, suggesting the rollout is expanding internationally. Tracker @NowRollingOut has also flagged the version and is monitoring for further details. European Tesla owners can now expect to see this update appearing in their queues in the coming days.
Tesla has begun seeding firmware 2026.38.6 to the fleet, with tracker data from TeslaFi and NotATeslaApp confirming the rollout started around October 28β29, 2026. Install counts are still in the low hundreds β a clear sign this is an early, limited seed β but the update is live and moving. Here's what we know so far and what you should do if you want it sooner rather than later.
What Changed
| Change | Type | Models |
|---|---|---|
| FSD Streaks β legacy Model S support added | π Undocumented | Model S |
Official release notes for 2026.38.6 have not yet been published by Tesla. The FSD Streaks addition for legacy Model S hardware was surfaced by community trackers, not Tesla's own changelog. Additional documented changes may surface as the rollout widens β we'll update this article when they do.
A note on Model S: While Tesla ended new Model S production in May 2026, existing customer-owned Model S vehicles continue to receive OTA software updates normally. This update is consistent with that ongoing support.

How to Check for the Update on Your Tesla
Tesla's OTA rollouts are staggered β not every car gets pinged at the same time. These steps won't force an install, but they give you the best chance of landing in an early wave.
- Check your current version first. On your touchscreen, tap Controls β Software. Note your version number so you know whether 2026.38.6 has arrived.
- Connect to Wi-Fi. Tesla strongly prefers delivering updates over Wi-Fi. Park within range of your home network and make sure the car is connected β tap the Wi-Fi icon in the top bar to confirm.
- Enable Advanced Updates (if available). In Controls β Software, look for the update preference toggle. Setting it to Advanced opts you into earlier access on eligible vehicles.
- Tap 'Check for Updates'. On the Software screen, pull down or tap the refresh option if your UI version supports it. This nudges the car to poll Tesla's servers.
- Leave the car plugged in and idle. Updates are typically staged while the car is charging or parked. Leaving it on the charger overnight significantly increases the chance of waking up to a new version.
- Track your wait via TeslaFi. If you want real-time rollout data, TeslaFi's 2026.38.6 tracker shows install counts and fleet coverage as the push progresses.
With only 238 installs confirmed so far, 2026.38.6 is still in a very narrow seed. Rollout pace typically accelerates over 48β72 hours once Tesla confirms stability β so if your car hasn't received it yet, that's entirely normal. Keep an eye on the trackers and check back here as the official changelog fills in.
