  • Tesla HW4 Computer Failures as FSD 13 Launches for AI4 Vehicles

    Tesla HW4 Computer Failures as FSD 13 Launches for AI4 Vehicles

    While drivers of older Tesla vehicles equipped with HW3 computers are eagerly anticipating the much-anticipated FSD 12.6 update, those fortunate enough to own newer HW4 models are already enjoying the latest FSD 13.2.1.

    Issues with the New AI4.1 Upgrade

    However, there’s a significant problem for buyers of the latest Tesla models, which come with an unannounced upgrade to the HW4 computer, referred to as AI4.1. These new units are reportedly experiencing failures shortly after purchase, causing them to shut down unexpectedly.

    In some instances, the AI4 computer breaks down after just a few hundred miles, leading to the loss of not only the FSD feature but also the functionality of cameras and GPS navigation, making range estimates impossible to determine. Reports suggest that this issue is quite common, with Tesla’s service team receiving numerous alerts regarding it. The potential cause seems to be a low-voltage system that could be damaging the HW4 system boards during the calibration of the cameras.

    Uncertain Causes and Possible Recalls

    It remains unclear what exactly is causing the short-circuiting that leads to the failure of AI4.1 computers in Tesla vehicles manufactured in recent months; this could potentially be a production flaw. If that’s the case, it may lead to a recall for full unit replacement, even though Tesla is reportedly trying to postpone this outcome with a software solution.

    Despite providing quicker AI processing capabilities, Tesla’s HW4 computer doesn’t offer many other benefits compared to the HW3 unit. The primary aim appears to be reducing production costs, as HW4 has less RAM and storage in models like the Model Y and Model 3, along with increased power consumption when not in use.

    Cost-Cutting Consequences

    Tesla might have pushed the boundaries of cost-saving measures too far with the AI4.1 version of their computer, leading to potential weaknesses. Elon Musk had promised that all HW3 computers would be upgraded to AI4 units for free if FSD 13 couldn’t be made functional on them. Given the issues with the AI4 computer, this assurance doesn’t seem as promising now as it did at the time of the retrofit announcement.

  • Tesla FSD V13.2 Launches: Full Parking Automation & 3-Point Turns

    Tesla FSD V13.2 Launches: Full Parking Automation & 3-Point Turns

    Tesla has unveiled its newest Full Self-Driving (Supervised) V13 edition, just a few months after the release of V12.5.

    Launch Timing and Features

    Previously, the AI team at Tesla had indicated that FSD 13 would be ready by October, likely coinciding with the Robotaxi demonstration. At the event, Cybercabs were indeed utilizing FSD 13. The public rollout has just occurred, and Tesla shared an extensive list of updates for FSD 13.2, highlighting improvements like a response speed that is twice as fast and enhanced collision avoidance, made possible by a three times larger AI model trained on computers that operate five times quicker.

    User Experience Enhancements

    While the statistics on processing capabilities, such as 5x-6x improvement in miles driven without needing intervention, are noteworthy, there are real benefits for users of FSD 13. For example, drivers can now engage FSD directly from Park with a simple button press. The new profiles for city and highway driving also contribute to a more pleasant driving experience.

    Development Insights

    Yun-Ta Tsai from Tesla mentioned the extraordinary effort to launch FSD 13:

    “We completely restructured the system to greatly simplify the flow—from direct photons to control—while adding much more functionality within the same unified framework. This is likely one of the most significant rewrites in years since we began our journey with ‘photon count’ four years ago.”

    New Functionalities

    Among the most noticeable features in FSD 13 are the capabilities for three-point turns and self-parking. The Tesla can now exit a parking spot, reverse, or park itself in locations like driveways or garages, with these features coming in a future update. FSD 13 also includes enhancements in camera visibility and cleaning, with plans for future updates to improve how the system handles camera view obstructions.

    Navigation Improvements

    FSD 13 can now identify road closures and suggest alternate routes, thanks to its ability to process mapping data more efficiently. Additionally, Tesla has tackled some common grievances of FSD users, such as unnecessary braking and overly cautious driving in parking areas.

    Hardware Limitations

    It’s unfortunate that all the new features in FSD 13.2 are only available for Tesla owners equipped with the latest HW4 or AI4 computer and camera systems. Most Teslas still operate on HW3, but Elon Musk hinted that the company might offer free upgrades to HW4 if it proves challenging to make the next unsupervised FSD update compatible with older hardware.

    With Elon Musk now leading the DOGE government efficiency department, the rollout of unsupervised FSD could happen more quickly, and it will soon be determined whether HW4 retrofits will be necessary.

  • Tesla Simplifies Identification of HW4 and HW3 Vehicles with License Plates

    Tesla Simplifies Identification of HW4 and HW3 Vehicles with License Plates

    Tesla has made it simpler for users to determine if their vehicles are equipped with HW3 or HW4 Full Self-Driving (FSD) cameras and processing power.

    With the most recent software update, version 2024.38, users can now view the FSD hardware version right in the additional vehicle info submenu. By selecting the Additional Vehicle Information option located under the FSD computer section in the Controls > Software menu, drivers can see if their Tesla features HW4, HW3, or the older HW2.5 setup.

    Understanding FSD Hardware Designations

    Tesla has rebranded Hardware 4.0 as the AI4 computer, which is how it appears in the fresh FSD hardware version display option. Previously, identifying whether a Tesla has a HW3 or HW4 kit has been quite complex, relying on physical traits such as the red tint associated with AI4 cameras or the vehicle’s delivery date.

    Although HW4 vehicles are still relatively rare, they were the first to receive the FSD 12.5 update. Tesla’s AI chief has indicated that these vehicles will also be prioritized for the forthcoming FSD 13 update, which includes new features.

    Free Upgrades for HW3 Vehicles

    Elon Musk has stated that if HW3 vehicles are unable to support the unsupervised FSD that comes with the v13 update, they will be upgraded to the AI4 computer at no cost. Initially, it was believed that retrofitting HW3 to HW4 was impractical due to differences in the system board size and connectors. However, visiting a Tesla service center will help navigate these constraints, as the company needs to collect miles driven on FSD to prove its safety to regulators overseeing the Robotaxi and Cybercab services.

    After introducing the FSD hardware version on the vehicle display, Tesla is also working on a feature to show the car’s license plate number. A hacker named Green has explored Tesla’s 2024.38 update code and discovered hints of a license plate number display on the central console screen. This feature appears to be rolling out first for Chinese models, as is common for the company, before becoming available worldwide.

    Personalization Options for Tesla Owners

    In addition to displaying the license plate number in the previously blank area, owners will have the ability to enter any text they wish. Parents whose kids enjoy customizing their virtual Teslas with unique colors will find this new feature to be another fun way to personalize their vehicle’s display, whether for a specific purpose or just for enjoyment.
