Tesla OTA 2021.12.5.7 Software Update Now Rolling Out For Some Instead of 2021.12.10

Tesla had just rolled out the 2020.12.10 software update less than a day ago for several vehicles, but it appears that some are now receiving the 2020.12.5.7 update instead. From what we can see, this Tesla software update is essentially the same as the Traffic Light and Stop Sign Control update late last week.



Based on some data we gathered, we’re seeing software updates from vehicles with these versions:

  • Majority of the 2020.12.10 updates previously had version 2020.12.5, these all had Model X, S or 3.
  • All the Model Y models that received 2020.12.10 update originally had versions 2020.5.10.7 or 2020.5.10.8
  • For vehicles receiving this latest 2020.10.5.7 update, they are either upgrading from version 2020.12.1 or 2020.12.5.6

Keep in mind these are from extremely limited data.

The official version number for this latest tesla sofware update is 2020.12.5.7 01a17392a3e6.

Tesla 2020.12.5.7 Release Note

Traffic Lights and Stop Sign Control (Beta)

Traffic Light and Stop Sign Control is designed to slowdown and stop for visible traffic lights or stop signs that are detected when Traffic-Aware Cruise Control or Autosteer is engaged. Driver accelerator or stalk confirmation is required to proceed through all traffic controls, including green lights. The vehicle will continue straight and will not make turns.

The Traffic Light and Stop Sign Control feature will not control for all intersections; therefore, you must pay attention and be ready to take immediate action at all times, including braking.

This feature may be conservative and slowdown often at first. Over time, as we learn from the fleet, the feature will control more naturally. Performance may be degraded in difficult environments with pedestrians, rain, direct sunlight or when approaching traffic controls that are obstructed.

Dashcam Viewer

Watch saved Dashcam clips or Sentry Mode events directly from the touchscreen with the Dashcam Viewer. To launch, tap the Dashcam icon in the status bar and select “Launch Viewer” while the car is in PARK. If the car is in DRIVE, you will continue to save a clip by tapping the icon.

To view saved clips and events stored on your USB drive, tap the Menu icon in the upper left corner of the viewer. Each video is organized by location, date and thumbnail for easy access. For additional filtering options, tap the “Dashcam” or “Sentry” tabs.

Select a clip or event to play the corresponding video. To select video from a particular camera, tap the associated thumbnail marked Front, Rear, Left or Right. Play, pause or scroll by using the video controls at the bottom of the player. To delete a video, tap the trash icon in the bottom right corner of the video player.

The driving visualization can now display additional objects which include stop lights, stop signs and select road markings. The stop sign and stop light visualizations are not a substitute for an attentive driver and will not stop the car. To see these additional objects in your driving visualization, tap Controls > Autopilot > Full Self-Driving Visualization Preview.

Out of Order Supercharger Stalls

Supercharger stations now identify the number of out of order stalls. To view the current availability, tap the Supercharger station map pin.
