Tesla’s software updates often contain far more than the release notes show, whether they’re undocumented features or preparation for the next big thing. The 2025 Spring Update is no exception - it’s filled with undocumented changes and, of course, new, inaccessible code that points to upcoming features.
Tesla hacker greentheonly on X has been digging into update 2025.14 and found some intriguing additions and hints about what’s coming next, so let’s take a look.
Grok Incoming
New hidden UI elements have been found pointing towards the integration of a Grok-powered smart assistant for Teslas. This includes references to a “personality” button, just like the Grok app. Tesla is likely hard at work on an advanced conversational AI and integrating the ability to control your vehicle.
Grok is the smart assistant that’s expected to replace the ancient voice commands that are available today. However, expect anything beyond vehicle commands to require Tesla’s Premium Connectivity.
While none of these new elements are active just yet, it is a good indication that it is likely on its way quite soon.
Siren Detection UI Removed
Code related to user-facing elements for siren detection has now been removed. We’ve confirmed that the orange dot is still in place with the Spring Update, but elements related to future changes and a UI for siren detection have since been removed from the code base.
Removals don’t indicate much - Tesla could be refactoring the code while they’re working on this or have changed directions on how to implement a future.
Insights into the New Dashcam Viewer
More significantly, for users on HW3, Green reported that the newly improved Dashcam Viewer isn’t just an improved version of the video viewer, but it was built from the ground up, and it’s now web-based. This technical detail explains why the updated viewer is only rolling out to AMD Ryzen vehicles and not older, Intel-based vehicles. HTML-based apps are often quicker to develop but usually require more resources to perform smoothly, which may be why we’re seeing the Ryzen infotainment system requirement.
This likely means that the new Dashcam Viewer won’t arrive on Intel vehicles in a future update unless Tesla can optimize the viewer enough to perform adequately on the older hardware.
HW3 vehicles already missed out on the new B-pillar recording feature. While Green thinks it’s technically possible to bring this feature to HW3 cars, unknown technical issues are likely preventing it. Older HW3 vehicles without a USB port in the glovebox only include USB 2 ports, limiting bandwidth, which could be one of the reasons, among others.
New Key Types
Perhaps a hint at Tesla’s third-party Robotaxi fleet ambitions, Tesla is building out new types of keys.
Rider Keys: These new keys appear to be designed to allow designated riders to access vehicles that are operating in “fleet mode.” This functionality sounds very much like what will be needed to allow Robotaxi customers to access a vehicle temporarily while they’re being given a ride.
Pre-Delivery Keys: Another new key type found is “pre-delivery.” While we don’t have an exact purpose nailed down quite yet, we’re assuming this could potentially allow new owners limited access to their vehicles for inspection prior to officially accepting delivery.
That’s plenty of interesting stuff found in the 2025 Spring Update - and we’re excited to see even more in just a few short weeks once Tesla launches their Robotaxi network in Austin.
