Tesla offered an early access program back in 2018 that allowed Tesla owners to sign up to receive early builds of Tesla software updates. Tesla used these vehicles to test software builds before they went out to the general public. Unfortunately, the program was phased out in 2019 as Tesla grew and sold more vehicles.
Today, Tesla allows employees to sign up for their “Wave 1” program to receive and help test early builds of software. While Tesla owners had to sign an NDA to not disclose new software features, restricting early software builds to just employees helps Tesla keep even tighter control of unreleased features.
Tesla also leverages influencers to help test new FSD builds once they pass internal testing. This lets YouTubers and other influencers show off the capabilities of new FSD features and keep owners excited. Influencers often receive new FSD builds several weeks ahead of the public and sometimes receive versions that aren’t released to the public, however, these builds are limited to FSD updates and do not include new features found in major software updates.
This updated early access program seems to focus specifically on FSD, rather than general software features, similar to how Tesla’s influencer early access program works today.
Tesla included the image above in the app, which seems to confirm that this program will focus on FSD/Autopilot features and not include new major updates like 2025.14.
There are a couple of possibilities on how Tesla might roll this out. The program could be offered to users in regions where FSD is already available, allowing newer builds to be tested more quickly. Alternatively, it could target regions that are expected to receive FSD Unsupervised first, such as Austin, Texas. However, the former seems more likely, especially considering Elon Musk’s recent comments during the latest earnings call about needing to meet a minimum safety threshold before deploying FSD Unsupervised to customer vehicles.
Early Access Program Terms
The decompile also provided an image of the early access program privacy policy, which appears to enable Tesla to pull even more data from opted-in users. It seems the early access volunteers will provide vehicle-specific and VIN-associated data, rather than the current anonymous data that is provided under Controls > Software > DataSharing.
This data will contain personal identifiers, including unique vehicle identifiers, account information, GPS data, interior and exterior camera recordings, and likely (but unmentioned) microphone recordings. Tesla could also pull information from the mobile app or contact you for additional details about specific events that it records while a user is enrolled in the early access program.

What You’ll Get
This is an exciting development—it’s the first time in a while that non-influencers can get early access to Tesla’s FSD builds. For FSD enthusiasts, it’s a great chance to experience upcoming features firsthand. Just keep in mind that early builds tend to be less stable than public releases, and extra attention is required.
One thing to keep in mind is that newer builds aren’t always better. Early access testers spent a while on a less stable build of FSD V12.4 as Tesla tried to iron out bugs, but ultimately, Tesla decided to pull FSD v12.4 and focus on v12.5, which eventually made a public release. FSD v12.4 was the first to introduce hands-free driver monitoring but struggled with lane keeping and lane selection.
However, if you consider yourself an FSD enthusiast and are ready to keep a vigilant eye on FSD, this new program could be a great chance to gain access to early FSD builds.
It’s still unclear how Tesla will select users for the program—or whether eligibility will depend on region or vehicle hardware—but we’ll share all the details as soon as they become available.

Tesla’s Vice President of Vehicle Engineering, Lars Moravy, recently took to X and opened the floor for user input. There, he asked the community for features and improvements they’d like to see to make Teslas better heading into 2026.
This post generated thousands of suggestions - and we recapped the best of them. There were also a few that Lars responded to, giving owners hope for some much-requested future changes, so let’s take a look at what may be coming
Lumbar Profile Support
Today, lumbar support is one of the few items that is not saved in the Tesla profile. That means if you have multiple drivers who use the same vehicle, you’re often left adjusting this setting manually, as it retains the setting that was last used. One community member suggested saving your lumbar setting to your profile just like Tesla does for other seat settings.
Lars said making this change seems doable, but it’ll take some engineering magic. The lumbar support isn’t tied to an absolute sensor like the other seat settings. This suggests that Tesla does not have an exact value to save, as it does with other seat functions, but Lars believes Tesla can find a way to save lumbar preferences. Tesla could potentially time how long the motor runs to get to the user’s lumbar setting and save this value.
With that said, it seems the vehicle engineering team may take a look at this one, and we may see it included in a future update.
Model 3 Signal Stalk Retrofit
The move away from traditional stalks in favor of the steering wheel buttons on the Refreshed Model 3 has been a point of debate. While the author is squarely in the camp of steering wheel buttons (at least with the Cybertruck), many dissent and say that the buttons on the Refreshed 3 aren’t as satisfying or easy to use.
Many other drivers also prefer the tactile feel and muscle memory of a physical stalk for signaling. Tesla appears to favor stalks, as they retained the turn signal stalk with the new Model Y. There are also rumors that Tesla is going to reintroduce the turn signal stalk to the Model 3.
If Tesla adds stalks back to the new Model 3, current 2024+ Model 3 owners are still left without stalks. However, a user suggested adding stalks as a retrofit option. Lars said that he would try to consider a retrofitted signal stalk for the Refreshed Model 3, similar to the simplified version in the Refreshed Model Y.
While less definitive than the lumbar support response, it appears that Tesla may at least consider offering a stalk retrofit for the new Model 3. If you’re a lover of signal stalks and can’t wait for Tesla to get an official one - we recommend the Enhauto S3XY Stalks, which are customizable and feel very close to Tesla’s original fit and finish.
With that said, it’s nice to see Tesla incorporating more community feedback into its vehicle design these days. Perhaps one day, they’ll address the infamous auto wipers. They have gotten better, but they’re still not as reliable as what’s available in most other vehicles. With that said, we look forward to the changes that will emerge from these recent conversations.
Sometimes, even with Tesla’s intensive bug-testing regime, bugs manage to make it out into the wild. In this particular case, a European user (@darkwaffle48484 on X) noticed that their 2024 Model 3 was using up more battery than normal while parked. Normally, they noted that the vehicle would lose about 1-2% per week; however, recently, they noticed much larger drops of 3-4% per night.
They monitored their Tesla widget and noticed the car wasn’t entering deep sleep. The widget consistently showed a recent connection time—usually within the past 45 minutes.
Fix Inbound
After discussing the issue with other Tesla owners and realizing it was somewhat widespread, they contacted Tesla Service. The service team confirmed that it was a firmware bug affecting the Telematics Control Unit (TCU), which prevented the vehicle from entering deep sleep mode.
The TCU is essentially the communications hub of your Tesla - and is mounted on the ceiling of newer vehicles such as the Model 3 and the new Model Y. It enables cellular and location services (via GPS) and also handles Wi-Fi and Bluetooth services. Tesla Service stated that this bug is planned to be fixed in update 2025.14.6, although the exact version number could change. However, they confirmed that they are aware of the issue and it is being addressed.

When the user reached out to Tesla Service, Tesla Service responded with the following (translated from Dutch):
“It has been confirmed that this is a firmware bug. The fix is in one of the next updates. Currently, it is planned for 2025.14.6 (subject to change). Do you have any more questions?”
Potentially Region-Specific
This bug could potentially be region-specific. TCUs often require specific hardware components, such as modems, as well as specific firmware versions that support different regions and cellular providers. These enable Tesla to comply with local cellular standards and regulations and ensure that your vehicle can connect to the networks available in that particular region.
At this point, it’s not clear when the fix will roll out, but given that update 2025.14.1 has practically stopped rolling out, Tesla may be waiting to resume the rollout with update 2025.14.3 or this 2025.14.6 version.
If you’ve noticed this issue and are in a non-European nation, let us know.
