Tesla software update 2026.2.3.17 was listed on October 28, 2026, adding another build to the 2026.2.3 family. Official release notes are not yet available, leaving its specific changes and vehicle compatibility unconfirmed. The listing establishes the version's appearance, but does not by itself confirm a rollout or identify a particular correction. Its numbering makes the earlier 2026.2.3 release a useful possible branch reference.
That earlier release, dated January 27, documented Unlatching Charge Cable for Model 3 and Model Y. Its notes described stopping charging and releasing the connector by holding the rear left door handle for three seconds, with the vehicle unlocked or a recognized key nearby. This offered an alternative when a connector button failed or an adapter was stuck; the touchscreen and Tesla App remained other release methods.
A separate entry in 2026.2.3 covered Child Left Alone Detection specifically for the new Model Y. It described repeated exterior light and sound alerts, together with a phone notification, when an unattended child was detected. Cabin information was processed locally, and the setting was enabled by default. Those details explain the older feature's purpose and conditions; they do not establish that this new build includes it.
The earlier package also listed general minor fixes for Model S, Model 3, Model X, and Model Y, with worldwide availability on that entry. It did not identify individual corrections. Consequently, that description cannot support a claim about a particular fault being resolved in 2026.2.3.17.
If this update continues the same branch configuration, some of those functions could remain part of its software package while further refinements may have been made. This is an editorial possibility, not a confirmed feature list. The version number alone does not establish hardware generation, regional eligibility, or a new FSD edition, and an older model restriction should not be broadened to other vehicles.
This same article will be completed when official release notes become available, with confirmed changes, supported vehicles, hardware requirements, regional conditions, and appropriate illustrations. Until then, the predecessor details provide background rather than verified release notes for this version.
