The first-gen Model 3 and Model Y will soon have support for their matrix headlights
Not a Tesla App
According to a new document in the EU, Tesla is preparing to enable its matrix headlights on the current Model Y and first-gen Model 3.
The document, dated January 3, 2024, reveals that Tesla is introducing adaptive high-beam support to these vehicles, similar to what they recently released on the new Model 3.
A similar document was leaked in December that showed that Tesla was looking to add adaptive high beams to the new Model 3.
Software Update
In Tesla software update 2024.2, Tesla introduced support for adaptive headlights in their newest vehicle, the new Model 3.
While this was the first Tesla vehicle to receive support for adaptive high beams, it left many vehicle owners wondering whether Tesla would enable support for matrix headlights that have come on vehicles for several years.
Supported Vehicles
According to this document, the approval is only for the Model 3 and Model Y. However, it’s almost certain that the update will also arrive on the Model S and Model X as well, although it could come in a separate, later update.
The first Model X vehicles with matrix headlights were delivered in June/July of 2023, while the Model 3, Model Y, and Model S have had matrix headlights for a longer period. Support on the Model 3 and Model Y has varied by region and model, so the best way to tell whether your vehicle has matrix headlights is to look at them. If you see a large, round projector lens like the image below, your vehicle has the new matrix headlights.

Video of Adaptive Headlights on New Model 3
X user m.jr.88 posted a video (below) of his new Model 3 that has support for the new adaptive high beams feature. In the video, you can see how select parts of the road brighten and dim as vehicles approach.
Will It Be Available Outside of the EU?
Headlights play an important role in vehicle safety and therefore adaptive headlights are often highly regulated by safety agencies. Due to the leaked document, it appears the feature will be available across the European Union, however, it’s not immediately clear whether it will be available in other regions at the same time.
In 2022, the NHTSA issued a ruling that automakers could install adaptive headlights in their vehicles. However, there could be specifications that must be followed in the U.S. or another region that could differ from EU requirements.
Tesla would without a doubt want to make this feature available in as many regions as possible; however, potential adaptations may be necessary to align with local market nuances and regulatory requirements. At this time, we would expect matrix headlights to become available in the EU soon, with other potential markets available at the same time or soon thereafter.
Release Date
The original document for the new Model 3 was dated November 8th, 2023, so it was about two months before Tesla introduced the update that enabled adaptive high beams on the 2024 Model 3.
If Tesla follows a similar timeline, we may see support for matrix headlights in the next 4-6 weeks. Tesla could add it as soon as the next major update, which is expected to be version 2024.6 or 2024.8.
Update 2024.2, which includes support for the new Model 3 is still in the early stages of rolling out with only about 1% of Tesla's fleet having access to the update. However, we'll likely see bigger waves roll out in the next couple of weeks.
Adaptive High Beam Release Notes
The release notes for adaptive high beam support in update 2024.2 states that the high beams will now adjust to reduce glare for other drivers and cyclists. It goes on to say that by detecting road users and selectively dimming individual pixels of the headlights, the high beams can remain on longer and provide better visibility.
The new adaptive high beam feature is disabled by default but can be enabled in supported vehicles by going to Lighting > Adaptive High Beam in the vehicle's settings.

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.
@darkwaffle48484
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.
