Tesla update 2026.38.5.12 has appeared on multiple US vehicles in TeslaFi’s sample.

Not a Tesla App lists the update on November 4 and includes the previously reported emergency charging-cable drive-away feature, phone-set arrival energy, select Supercharger site maps for Intel-equipped vehicles, and security improvements. Its notes do not specify a new bug fix unique to this version.

TeslaFi’s installation chart begins November 4; its November 5 US records include Model 3, Y, X and Cybertruck installations. These are third-party, opt-in sample observations—not proof of general fleet availability or eligibility for every vehicle. Feature availability varies by model and hardware.
