Tesla App 4.48.0 Update: Cool Features, But Watch Out for the Phone Key Bug!

Tesla recently unveiled version 4.48.0 of its app, which is designed to enhance the experience of Tesla vehicle owners worldwide. This latest version, released on August 21, 2025, introduces several pivotal updates aimed at improving vehicle connectivity, security features, and user interface. However, it comes with a significant warning due to a bug related to the phone key function. This glitch removes pre-configured phone keys, requiring users to utilize their card keys for reset or manual unlocking via the app. Tesla advises caution and recommends waiting for a rectifying update before installing version 4.48.0, as detailed in the release notes.

One of the standout features of this update is the integration of B-pillar dashcam viewer support. Previously, footage from these cameras, which are strategically located on the vehicle's B-pillars, were only accessible from within the vehicle. With this update, owners can now remotely view this footage through the app, enhancing the app's functionality for vehicle surveillance and security. This feature not only amplifies the security measures available to Tesla owners but also marks a significant technological advancement for HW4 Tesla vehicles, with plans to extend this support to the Cybertruck, as discussed in the update details.

In addition to these enhancements, Tesla is laying the groundwork for future improvements by preparing to introduce a message search function within the app. This upcoming feature aims to streamline communication by allowing users to efficiently search through their Tesla app messages for important vehicle alerts and delivery information. Such improvements are poised to significantly bolster the app's user-friendliness and practicality, envisioning a future where app-based vehicle management is markedly more seamless, as noted in the release summary.

The release of Tesla App version 4.48.0 on August 21, 2025, brings with it several significant updates along with some challenges. One of the key issues identified is the Phone Key bug, which has led to the inconvenience of phone keys being removed post-update. Consequently, Tesla vehicle owners are advised to carry their card keys to reset the phone key settings. This has prompted Tesla to caution users to delay updating the app until a resolution is provided. The introduction of the B-Pillar Dashcam Viewer feature is a major enhancement, allowing users to view footage recorded from the vehicle’s B-pillar cameras directly on the app, a functionality previously restricted to HW4 vehicles and soon to be extended to the Cybertruck. Additionally, Tesla is setting the groundwork for a future feature that will enable users to search through Tesla app messages, enhancing user experience by making it easier to locate important vehicle and delivery information. These updates reflect Tesla's commitment to continually improving the functionalities and convenience of their mobile app for vehicle owners.

The Phone Key bug in the latest Tesla App version 4.48.0 has posed significant inconvenience to Tesla owners by unexpectedly removing pre-configured phone keys upon updating the app. This issue necessitates the use of a physical card key to reset the phone key in the app, a step that's quite cumbersome for users who primarily rely on their smartphones for vehicle access. Furthermore, if the card key is unavailable, drivers must resort to manual unlocking and starting through the app, leading to increased frustration. Tesla has acknowledged this glitch and is actively working on a solution, advising users to defer the update until a rectification is issued.

Tesla's latest app update, version 4.48.0, brings significant advancements with the introduction of B-pillar dashcam viewer support. This feature notably enhances remote surveillance capabilities by allowing users to view footage from their vehicle’s side-facing B-pillar cameras directly through the mobile app. Previously, this access was limited to the vehicle itself, meaning that owners can now monitor their vehicles' peripheries even when away, directly from their smartphones. Such a feature is expected to boost security and provide peace of mind for vehicle owners, especially those concerned about theft or vandalism in environments where their vehicles are parked.

This integration of B-pillar camera functionality into the Tesla app not only marks a technological upgrade but also aligns with the industry trend towards increased connectivity and control over vehicle systems remotely. By allowing access to these camera views externally, Tesla further blurs the lines between in-vehicle and remote monitoring, providing a seamless experience for users. This feature, already available in Tesla's HW4-equipped vehicles, sets a precedent for upcoming models like the Cybertruck, which will also receive this functionality according to the update notes.

The addition of the B-pillar dashcam viewer not only enhances security but also represents Tesla's commitment to continually improve the user experience through software innovations. Owners can now utilize this new feature to keep a vigilant eye on their surroundings, facilitating a more proactive approach to vehicle security management.

The upcoming search feature in the Tesla app, aimed at streamlining the way users access important vehicle and delivery messages, promises to be a significant enhancement for Tesla owners.

This approach not only mitigates the risk of introducing large-scale errors but also allows users to adapt to new functionalities without overwhelming them. Such enhancements speak to Tesla's broader strategy of leveraging software updates to refine and augment the connected vehicle experience, solidifying its reputation as a leader in automotive technology innovation.
