π UPDATE β August 20, 2026
Tesla has launched the 8th wave of the 2026.26.6.1 rollout, pushing the update to approximately 4,070 additional vehicles in just the last five minutes according to Teslascope fleet data. The deployment has accelerated significantly from the 212 installs tracked at initial publication. The wave continues to deliver minor fixes alongside the Summer Update 2026 feature set. If you haven't received your notification yet, now is a great time to try the force-check steps outlined below.
π UPDATE β August 19, 2026
Tesla's 2026.26.6.1 rollout has now reached its 6th batch of owners, covering approximately 23% of the fleet. While the .1 point release itself carries only minor fixes, the key feature in the broader 2026.26.6 Summer Update is now confirmed: the Estimated Range calculation has been updated to account for battery aging. This means owners of older vehicles should see a more accurate β and likely more honest β range estimate that reflects real-world battery degradation rather than original factory specs. This is a meaningful quality-of-life improvement for long-term Tesla owners who have noticed their displayed range drifting from reality over the years.
π UPDATE β August 18, 2026
The rollout of 2026.26.6.1 has accelerated significantly. Teslascope reports the update pushed to roughly 2,970 additional vehicles within a five-minute window this morning, and @NowRollingOut confirms this is now the 6th wave of distribution. Fleet penetration is approaching ~18% of tracked vehicles, according to The Tesla Newswire.
The headline feature carried over from the base 2026.26.6 release is an enhanced Estimated Range calculation β the battery range display now factors in battery aging characteristics, meaning owners with older packs should see a more accurate (and honest) range estimate rather than the optimistic figures based on a new-battery baseline. The .6.1 patch itself adds minor fixes on top of this.
π UPDATE β August 16, 2026
The 2026.26.6.1 rollout has accelerated significantly β Wave 5 just pushed to approximately 3,740 additional vehicles in the last few minutes alone, a major jump from the 212 installs tracked at the time of our original report. According to @NowRollingOut, this fifth wave confirms the build carries minor fixes and the full Summer Update 2026 feature package. If you haven't received your install notification yet, now is a great time to force a check via your Tesla app or in-car Software menu β the rollout is clearly ramping up fast.
π UPDATE β August 15, 2026
A 4th wave of 2026.26.6.1 is now rolling out, with Teslascope tracking approximately 3,520 additional vehicles receiving the update in just the last five minutes β a significant jump from the 212 installs reported at original publish time. The wave still carries the Summer Update 2026 package along with minor fixes.
Notably, owners are reporting meaningful real-world improvements to autonomous parking. @wholemars reports their Tesla successfully parked itself in a Costco lot for the first time, describing the car as now driving slowly and scanning for open spots rather than speeding around the lot in circles β a clear behavioral change worth watching for after your update installs.
π UPDATE β August 14, 2026
Tesla has launched a third wave of the 2026.26.6.1 rollout, pushing the update to approximately 1,870 additional vehicles in just the last few minutes according to Teslascope fleet data. That's a significant jump from the 212 installs tracked at the time of our original article, signaling the deployment is now moving into a much broader phase. As confirmed by @NowRollingOut, this wave still carries the same payload: minor fixes plus the Summer Update 2026. If you haven't received your install notification yet, now is a great time to try a soft reboot and ensure your car is on Wi-Fi β the expanded wave means your odds of getting queued just improved considerably.
π UPDATE β August 14, 2026
The rollout of 2026.26.6.1 is accelerating faster than initially tracked. A second wave has already been detected as of this afternoon, confirming Tesla is pushing the update more broadly. The release is confirmed as part of the Summer Update 2026 package and carries the Estimated Range feature from its parent build 2026.26.6 β which improves battery range estimation by incorporating additional vehicle characteristics β alongside minor fixes. The first wave reached approximately 2% of the fleet; the second wave suggests wider distribution is now underway. If you haven't received a notification yet, now is a good time to try a soft reset and ensure your car is connected to Wi-Fi overnight.
Tesla has begun pushing firmware version 2026.26.6.1 to the fleet. Early tracking data from TeslaFi and NotATeslaApp shows 212 confirmed installs and fleet coverage sitting at 0.2% β meaning this is still in the earliest wave of distribution. If you haven't seen it yet, that's expected. Here's what to do while you wait.

At 0.2% fleet coverage, 2026.26.6.1 is a point release β almost certainly a minor iteration on the broader 2026.26.6 branch rather than a feature-heavy drop. Tesla typically uses these sub-releases to address specific bugs or stability issues identified in the parent version's rollout. Official release notes have not yet been published; check all software updates as we update this page when the changelog goes live.
Action Plan
Early-wave distribution is partly random, but there are a few things you can do to improve your odds of landing in the first batch.
- Set your update preference to "Advanced." Go to Controls β Software β Software Update Preference and switch to Advanced. This opts your car into early releases before they reach the broader fleet.
- Connect to Wi-Fi at home. Tesla prioritizes Wi-Fi for OTA delivery. Plug in overnight with a stable home network β the car will download and stage the update automatically.
- Check for an update manually. In the Software menu, tap Check for Updates. This won't force a push, but it confirms whether your vehicle has already been queued.
- Don't dismiss the notification. If you get a prompt, install it. Delaying repeatedly can push you further back in the queue for the next release.
- Verify the version after install. Go to Controls β Software and confirm the version reads 2026.26.6.1. If it shows 2026.26.6 without the .1 suffix, you're on the parent release β the point update may follow shortly.

We'll update this article the moment Tesla publishes release notes or community reports surface confirmed changes. If you've already received 2026.26.6.1, drop what you're seeing in the comments β early owner reports are often the fastest way to piece together what a point release actually fixes.
