Tesla software update 2026.2.3, released on January 27, 2026, covers vehicle convenience and software maintenance. Its 3 documented entries explain changes to the ownership experience, from the features used inside the cabin to the software operating behind them. Availability depends on the vehicle and the requirements of each entry.
The feature list covers Model 3, Model Y, Model S and Model X. Some features are restricted to newer vehicles or specific configurations; support should be checked entry by entry.
Unlatching Charge Cable lets Model 3 and Model Y owners stop charging and release the cable by pulling and holding the rear-left door handle for three seconds. The vehicle must be unlocked or recognize a nearby key. This provides another option when the charging cable does not have its own release button, alongside the touchscreen and mobile app.
Child Left Alone Detection is listed for newer Model Y vehicles. If an unattended child is detected, the vehicle flashes its exterior indicator lights, sounds an alert and sends a Tesla app notification. The alerts repeat at intervals until the owner returns. Detection is enabled by default, with cabin information processed locally rather than sent to Tesla.
The child-detection entry processes cabin information locally and does not transmit it to Tesla. Its default-on behavior is paired with repeated notifications, giving the owner both vehicle-based and phone-based alerts. The setting is available through Controls > Safety > Child Left Alone Detection, where owners can review or disable it.
The model requirement is important when comparing this update with another Tesla: the child-detection feature is specifically listed for newer Model Y vehicles. A release number shared by several vehicles does not mean that each vehicle receives the same detection capabilities or cabin features.
Minor Fixes groups the smaller corrections and improvements supplied with the update. The description does not name individual faults or additional capabilities, so it should be read as a maintenance entry alongside the features that receive their own explanations.
Below, you can find the individual 2026.2.3 Release Notes, with images and the vehicle and hardware requirements for each documented feature.
