Tesla software update 2026.2.3.1 was listed with a release date of February 13, 2026. Its official release notes are not yet available, leaving the specific changes and vehicle compatibility unconfirmed. The version number suggests a relationship to the earlier 2026.2.3 configuration, although that connection remains an editorial interpretation rather than a confirmed upgrade path. The earlier 2026.2.3 notes were dated January 27, 2026, making them historical context for this listing rather than evidence of a newly announced feature.
One possible predecessor is 2026.2.3, whose official notes described charging-cable release through the rear left door handle on Model 3 and Model Y, an unattended-child alert for the new Model Y, and minor fixes. The original feature list therefore offers a charging and cabin-alert context for this branch, with distinct vehicle requirements rather than a single feature package for the entire fleet.
The additional suffix in 2026.2.3.1 could indicate a continuation of that earlier configuration. If so, the software may preserve its existing functions while incorporating subsequent adjustments. However, no particular correction or inherited feature has been verified for this build. Even when an earlier release lists minor fixes, that description cannot establish what changed in a later version without its own official notes.
The exact supported models, hardware generations, and regions for this build have not been confirmed by an official feature list. Earlier vehicle requirements are included to explain the possible software lineage; they do not establish eligibility for this release. Owners should use their vehicle's own update information to determine which features are actually available after installation.
This article will be updated when official release notes become available, replacing the provisional assessment with confirmed changes, vehicle compatibility, hardware requirements, and regional conditions. Until then, the earlier features described here provide context for a possible continuation of the branch and should not be read as the confirmed release notes for this version.
