Tesla Update 2025.45.9: FSD v14.2.2.4 Arrives

Tesla’s incremental software rollout strategy continues with the release of update 2025.45.9 . This over-the-air update began appearing on vehicles starting January 23, 2026, and brings the latest iteration of the Full Self-Driving suite to compatible Tesla vehicles .

FSD v14.2.2.4 Takes Center Stage

The headline feature of update 2025.45.9 is Full Self-Driving (Supervised) v14.2.2.4 . This version represents Tesla’s continued refinement of its autonomous driving technology, building upon the foundations laid in previous v14.2 releases. According to tracking data from Not a Tesla App, this update has been installed on approximately 96-100 vehicles, representing about 0.7-0.8% of the fleet as of its initial deployment .

FSD v14.2.2.4 includes several notable improvements to the driving experience. The neural network vision encoder has been upgraded to leverage higher resolution features, enhancing the system’s ability to handle emergency vehicles, road obstacles, and human gestures . The update also introduces “Arrival Options,” allowing drivers to select preferred parking locations such as parking lots, streets, driveways, parking garages, or curbside spots—a feature designed with Robotaxi-style drop-offs in mind .

New Speed Profiles have been added to further customize driving style preferences, including SLOTH for more conservative driving and MAD MAX for more assertive behavior with higher speeds and more frequent lane changes . The driver profile now has a stronger impact on behavior, with more assertive profiles allowing higher maximum speeds .

Emergency vehicle handling has been improved, with FSD now able to pull over or yield for police cars, fire trucks, and ambulances . The system also incorporates navigation and routing into its vision-based neural network for real-time handling of blocked roads and detours.

Beyond FSD: Additional Features and Improvements

While FSD enhancements dominate the release notes, update 2025.45.9 includes several other noteworthy additions . The Tesla Photobooth feature transforms the vehicle into a selfie station, allowing occupants to apply filters, stickers, and emojis to photos captured from inside the car . Dog Mode now includes a Live Activity feature on iOS devices, providing real-time updates on temperature and climate conditions for pets left in the vehicle, along with periodic cabin snapshots for Premium Connectivity subscribers .

The Dashcam Viewer has been enhanced with additional metadata, displaying speed, steering wheel angle, and self-driving state during playback on both the vehicle display and Tesla App . Navigation improvements include the ability to reorder favorites, set Home or Work locations by dropping pins on the map, and view suggested destinations based on recent trips and habits .

For owners of newer Model Y vehicles (2026+), the update adds automatic narrow field washing for the front camera, providing rapid and efficient self-cleaning capabilities . The Paint Shop feature, previously available for Model 3 and Y, has been extended to the Cybertruck, allowing owners to customize their vehicle avatar with new wraps, window tint options, and license plate designs .

The Path to 2025.45.9

The 2025.45 software branch has seen a steady progression of updates. This release follows 2025.45.5, which appeared in December 2025, and subsequent versions 2025.45.6, 2025.45.7, and 2025.45.8 . According to Teslascope tracking, 2025.45.9 was released on January 23, 2026, with a follow-up bug-fix version, 2025.45.9.1, appearing on February 8, 2026 . This suggests Tesla continues its rapid iteration cycle, addressing issues and refining performance based on real-world data.

Deployment Across the Fleet

The update is being deployed across the Tesla lineup, including Cybertruck, Model 3, Model Y, Model S, and Model X vehicles equipped with Hardware 4 . According to tracking data, the rollout has been gradual, with many installations occurring in the United States and Canada throughout February 2026 . The release history shows both AWD and Performance variants across model years 2024, 2025, and 2026 receiving the update .

Bug Fixes and Refinements

While not explicitly detailed in the release notes, the incremental nature of the update suggests it includes various bug fixes and performance refinements . The FSD v14.2.2.4 version notes mention improved ability to manage system faults and recover smoothly from degraded operation, enhancing overall reliability . Additionally, the update addresses camera visibility concerns with new alerting for residue build-up on the interior windshield that may impact front camera visibility .

However, some owners have reported issues following the installation of 2025.45.9, including camera and autopilot functionality problems . These reports suggest that while the update brings significant improvements, there may be compatibility issues with certain vehicle configurations. As always, Tesla continues to monitor and address such concerns through its iterative update process.

The Future of FSD

According to release notes, Tesla is already working on upcoming improvements, including enhanced overall smoothness and “sentience” in FSD behavior, as well as better parking spot selection and quality . These planned refinements indicate that Tesla’s development cycle remains active, with continuous improvements being developed for future releases.

The 2025.45.9 update demonstrates Tesla’s commitment to iteratively improving its vehicles through software, with each release building upon the last to enhance safety, convenience, and the overall driving experience. As the FSD system continues to evolve, updates like this one bring Tesla closer to its goal of full autonomous driving capability.
