Tesla will now show you which apps are using your location

In an undocumented change in Tesla update 2024.20 and later, Tesla has added a minor, but privacy-focused change to its software. Tesla has a user privacy-first focused policy, which aligns with the expansion of user privacy changes.

Location Privacy

Since late 2023 (update 2023.38), Tesla has been showing a small location icon at the top of the screen any time the vehicle’s location is being accessed, either by Tesla or a third-party app.

This includes someone using the Tesla app, which displays the vehicle’s location on a map. However, as of update 2024.20 and later, Tesla is now expanding the information shown.

Previously, when the icon was tapped, it would display a general message explaining why the icon was appearing. The message stated:

“This icon appears when an app requests your vehicle's live location data.
You can turn off sharing anytime in Controls > Safety > Allow Mobile Access, including all Tesla app access.
When this setting is on, your vehicle communicates directly with the Tesla app and other apps, but Tesla doesn't track your location.”

The same text is still displayed, but now boldly says, “This icon appears when an app requests your vehicle’s life location data.”.

More importantly, Tesla now displays the service that is accessing the vehicle’s location (h/t DriveTeslaCanada). So if someone opens the Tesla app, the vehicle will now display that the vehicle’s location is being accessed by the “Tesla Mobile App.” In addition, it appears to also display which Tesla driver or account is viewing the location of the vehicle. If it’s a third-party app or service accessing the vehicle’s location, Tesla will display the name of the registered third-party app.

Disabling Location Sharing

Tesla states that you can still turn off sharing in the same location as before (Controls > Safety > Allow Mobile Access), but doing so prevents many features of the Tesla app from working. If you use a third-party service, the location information is also tied to gathering detailed data on the vehicle, making it an “all or nothing” option.

If you have a service request active, Tesla Service may also ask you to re-enable Location Services so that Mobile Service can find your vehicle.

Unfortunately, there isn’t a history of which apps have accessed your vehicle’s location over a certain period. The location icon and detailed information are only available for a few seconds when the icon is displayed.

Tesla Smoking While Supercharging? A Look at What's Actually Happening

Winter is here, and temperatures are dropping, so one of the most common Tesla questions is about to resurface.

If you’ve landed here after frantically searching about “smoke” coming from your Tesla while Supercharging, take a deep breath—it’s completely normal.

Tesla Smoking While Charging

If you’re Supercharging in freezing weather—even with preconditioning—you might notice steam rising from your Tesla. But rest assured, your car isn’t smoking.

Your Tesla’s heat pump is hard at work warming both the cabin and battery to keep you comfortable and ensure optimal charging temperatures. Over time, condensation and ice build-up in the heat exchanger coils.

Why Does It Happen?

When you reach a Supercharger with your vehicle, the heat pump is still running hot, but without the cold air from driving to keep the heat exchanger coils cool, the ice and condensation quickly start to evaporate—creating what looks like smoke.

Since this typically happens near the front of the vehicle, where a car would traditionally have an engine, new vehicle owners can be startled by the discovery. However, rest assured that it’s just water vapor and it’s completely normal in cold weather.

In fact, this behavior can be experienced in any EV with a heat pump in cold climates. So, if you saw steam coming out of your vehicle and panicked, don’t worry—you’re not alone.

Now that you know what’s happening, go ahead and Supercharge with confidence.

Tesla Improves YouTube App With Smoother Playback

February 12, 2025

Not a Tesla App

Tesla made a lot of improvements in the 2024 Holiday Update, including more than 15 undocumented improvements that were included in the release. One of these was a stealthy performance improvement to the YouTube app.

Several people have mentioned they’ve seen improved performance on YouTube since this year’s Holiday Update - and there’s an interesting reason why.

YouTube Improvements

The improved YouTube performance in Tesla vehicles comes from an unexpected source—Tesla actually rolled back support for YouTube’s newer AV1 video encoding. Instead, vehicles now default to the older VP9 encoding standard.

While AV1 is highly efficient in terms of bandwidth, it requires considerably more processing power to decode and display videos. VP9, on the other hand, is less computationally demanding but uses more bandwidth to achieve the same video quality. This trade-off means smoother playback and better overall performance, even if it comes at the cost of slightly higher data usage.

Intel Inside

The VP9 video codec that the YouTube app is now using is much easier to decode, making it less taxing on the vehicle’s processor. This change is particularly beneficial for Tesla vehicles with Intel processors, which previously struggled to stream video at just 720p. When using AV1, these vehicles often experienced stuttering, sometimes forcing the YouTube app to automatically downgrade playback to 480p.

With this update, Intel-based Teslas should now be able to stream at 1080p smoothly. Streaming at 1440p is also possible, although occasional stutters still occur as the system keeps up with the decoding process.

Intel-based vehicles are the big winners with this change, but this appears to affect AMD Ryzen-based infotainment units as well, providing even smoother playback.

Chromium Web App

Tesla’s Theater apps aren’t native applications; instead, they run as chromeless web apps, leveraging the open-source browser built into Teslas known as Chromium (the open-source version of Chrome). Although this works quite well, there is a severe limitation - Chromium hardware acceleration isn’t supported on Linux, the operating system Tesla uses for their OS.

As a result, Tesla vehicles rely on software decoding instead of hardware decoding, which would otherwise handle video playback far more efficiently. A potential solution could be for Tesla to transition away from Chromium-based web apps in favor of a Mozilla Firefox-based browser, as Firefox does support hardware acceleration on Linux. This switch could also open the door to better streaming performance and the possibility of expanding Tesla’s in-car entertainment options.

However, Tesla’s choice of Chromium likely stems from Digital Rights Management (DRM) requirements for streaming services like Disney+ and Netflix, which rely on DRM-enabled playback. Firefox on Linux has had inconsistent support for DRM due to codec availability and variations in operating system versions.

We’re hopeful that Tesla will either adopt Firefox or develop a fully native application to improve video streaming, rather than continuing with the current web-based Tesla Theater. This shift could also pave the way for additional in-car applications built on Tesla’s native Linux environment—perhaps even reviving the long-rumored Tesla App Store.

Regardless, this update is a welcome improvement, particularly for YouTube, which remains one of the most widely used Theater Mode apps due to its accessibility, free content, and mix of short and long-form videos. It remains to be seen whether similar improvements are made for Netflix, Disney+, or other streaming platforms.

If you’ve noticed improved performance in Theater Mode, now you know why.
