Tesla's Holiday Update has made the most wonderful time of year the hap-happiest season of all. Adding to the parties for hosting, marshmallows for toasting and caroling out in the snow have been significant advancements to the user interface, the apps and the farts. So, in the spirit of reflection, let's look back at the last five years of updates courtesy of Santa Musk and the Tesla Elves.
2018
The 2018 update was significant because it was the first to go to the Model 3. Yes, it's hard to believe the Model 3 was celebrating its first Christmas five years ago. This update brought the browser, calendar and energy app to the 3, plus much more to the rest of the lineup.
Navigate on Autopilot made its first appearance in Beta. It suggests lane changes and monitors surrounding traffic to make adjustments to ensure you don't get stuck behind slower traffic. Autosteer and Auto Lane Change were also combined in a beta feature. If you were around when these features were first introduced, you know exactly how far they've come. Plus, Blindspot Warning was introduced. You can see how these are now utilized with today's vehicles, combining the technology as the company works towards Full Self Driving.

Another significant advancement in how Tesla operates came with increased regenerative braking. Tesla continues to lead the EV market in regenerative braking, and this update allowed more kinetic energy to return power to the battery.
2019
There was more fun in 2019, with the addition of the Tesla Theater, a new arcade game (Cuphead) and more media options. But, first, carrying over from 2018, yet another piece in the Autopilot collection was unveiled with Smart Summon, allowing users to have their Tesla come to them.

The Theater brought Netflix into Tesla, of course, when in park, so those waiting for their spouse to finish Christmas shopping could sit back and binge-watch their favorite shows. Nothing to watch? Tesla has you covered with Caraoke. This road trip favorite was also launched in 2019 alongside the inclusion of Spotify in the US market.
2020
In 2020, Tesla stuffed three new games down the chimney and into cars worldwide. The games were Cat Quest, the Battle of Polytopia and Solitaire. Is anyone else happy Steam was added in 2022?
While the entertainment addition wasn't at the same level as the previous year, made several UI improvements with driver visualization improvements, scheduled departure upgrades, Boombox and improvements to Emissions Testing Mode and Text messaging.
2021
2021 was a magical year allowing users access to the side camera to act as a blind spot camera. This welcome improvement caught Tesla up to the legacy automakers in that regard. From a usability standpoint, the company made the app launcher customizable and simplified controls so drivers can focus on navigation and primary controls, although there were some UI changes that needed to be gradually rolled back or reworked.
Three more video games were added, Sonic the Hedgehog, The Battle for Polytopia (Multiplayer) and Sudoku. Did I mention I'm happy Steam was introduced in 2022?
Since the update came out in December, its fitting cold weather improvements and automated seat heaters were included. Tesla also introduced the ability for seat heaters to be automated based on the desired cabin temperature. The Car Wash Mode was added, and perhaps one of the most used features, Sentry Mode Live Camera Access.
2022
That brings us to 2022. The year Steam was put inside the newer Model S and Model X cars, giving users the ability to access more than 50,000 high-end, high-resolution games. Apple Music, MyQ garage door opener, and Zoom were also wrapped up and put under the tree.
Tesla's incredibly generous gifting continues to have hearts glowing over the holidays. Just 12 months until the next big update. Let us know what's on your wishlist and be sure to stay on the nice list!

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 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.
