Tesla's new High Fidelity Park Assist feature in the holiday update

Tesla's 2023 Holiday Update is rolling out to happy customers around the world, and it includes everything we've heard about, from the NHTSA-related changes to FSD Beta 11.4.9, High Fidelity Park Assist, Custom Lock Sounds, and more.
However, the most exciting feature in the update is undoubtedly Tesla's updated Park Assist feature with new visualizations.
This feature provides a 3D reconstruction of the vehicle's surroundings while parking, akin to a 360-degree camera, but with 3D models that are built in real-time.
The system is leveraging Tesla Vision to create the surrounding environment, such as cars, pillars, bikes and other nearby objects. It certainly may not recognize what all the objects are, but it can define its outlines and build a 3D model.
Each 3D model is gray, but changes color the closer the vehicle gets to the object. The objects go from gray to yellow, to orange, and then finally red.
This is the first time we're seeing Tesla render 3D models using vision in a manner that LiDAR would be used.
Since these are actual 3D models, you can even pan and rotate the on-screen models to view them from various angles.
Requirements
Many vehicles are receiving the new Park Assist, however, it's not everyone. Vehicles running hardware 3 and hardware 4.0 are both receiving it, which is good news, but there are some limitations. It’s not particularly clear yet, but it appears that the feature may be limited to Ryzen infotainment units, or it may be rolling out to vehicles without ultrasonic sensors (USS) first.
If it's the latter, then there's no doubt that Tesla will expand this to vehicles with USS at some point in the future.
Future Visualizations
The visualizations provided by Park Assist are surprisingly good and accurate. They appear to be much more accurate than Park Assist has been in the past for vehicles without USS. For those owners, this will be a great enhancement that is not only exciting but useful when parking or getting around tight corners.
From the early videos and images we've seen, the visualizations look fantastic. We may be looking at upcoming FSD Beta visualizations in this new holiday feature.
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.
