For most vehicles, Charge HQ requires software version 2024.38 or higher, beginning February 2025. This is required in order to support fleet telemetry - for more details see Tesla Fleet Telemetry FAQ.
For pre-2021 Model S & X there is currently no minimum software version required.
If your vehicle is running an unsupported software version in February 2025 then Charge HQ will no longer function correctly. In this case a notice will be displayed on the Charge HQ home screen.
To continue to use Charge HQ please update your vehicle to a supported software version.
Tesla are continually making improvements to their vehicles via software updates - it's one of the great things about owning a Tesla. Along with these improvements come changes to the mechanism used by Charge HQ to access the vehicle - the Tesla Fleet API.
Charge HQ relies on certain features being available, which requires a minimum software version. In particular, version 2024.38 or higher is required in order to support fleet telemetry.
