Tesla has made significant changes in a recent software update, particularly regarding the 12V power sockets and USB ports. These commonly used features, which previously allowed Tesla drivers to charge various devices such as phones, tablets, and external electronics, are now subject to new restrictions. This update disables these ports when the vehicle is not powered on.
Tesla Restricts 12V Power and USB Ports Functionality
Before the 2024.32 update, the 12V power sockets and USB ports in Tesla vehicles were functioning normally and were freely accessible. However, after the new software update, things have changed as the update restricted the usage of these power outlets. Tesla owners can no longer use these power outlets once the vehicle enters sleep mode.
This means that the power outlet no longer provides constant power while the car is stationary. Moreover, these ports will remain off even when the vehicle is unlocked.
Power will only be available when the vehicle detects a user inside the driver’s seat or when interacting with the touchscreen. The new restriction is designed so that if there is no one inside the vehicle, the sockets will not function, rendering these accessories almost useless. In the software update changelog, there was no mention of these changes affecting the 12V power sockets and USB ports.
The Interior Electronics section of the Owner’s Manual has been updated, and it now states that these ports are only powered when someone is in the car or interacting with the touchscreen.
Note: Power is available when the vehicle detects that a user is present. A user is considered present when a person is in the driver’s seat or interacts with the touchscreen. Power is also available whenever the low-voltage battery is being charged or is in use, when you charge the high-voltage battery, or when the vehicle is communicating with the mobile app. Leaving an accessory plugged in does not deplete the low-voltage battery.
Reason Behind the Changes
Tesla has not provided a detailed explanation for the restrictions, but it’s widely believed to be an effort to optimize battery life cycle and enhance vehicle efficiency. The new restrictions are designed to conserve the car’s battery pack system and reduce the potential long-term drain. Previously, drivers could leave devices plugged in and charging even when the vehicle was not in use, potentially consuming power over an extended period.
Now, by limiting the functionality of these outlets to when the vehicle is in use, Tesla aims to extend the life of both the 12V battery and the main battery, thereby reducing the chances of long-term drain and maintenance costs for owners.
Another reason could be that accessories plugged in for an extended period could lead to overheating, potentially causing a fire in the vehicle.
However, users can bypass these restrictions by using Camp Mode, which allows power to continue flowing to these sockets. But this mode also has a disadvantage. While using this mode, you must be present in the vehicle. During the day, while out sightseeing or hiking, the fridge no longer works because Camp Mode is off. Additionally, Walk-Away Door Lock is inactive when Camp Mode is on.
Conclusion
Many owners are not happy with these changes and are requesting that Tesla provide an option to override these settings, allowing them to keep power available while understanding the risks involved. This update has generated considerable feedback from users, especially those who heavily rely on these essential features.
