Tesla Update Breaks Third-Party V2L Devices
Software version 2026.38.5.1 disables aftermarket vehicle-to-load adapters that draw power from Tesla batteries.
Tesla owners report that update 2026.38.5.1 interferes with third-party V2L devices connected via the CCS port. These adapters previously allowed power draw by mimicking a DC charging session, but now trigger faults and shut down after minutes of use.
Forum users on Tesla Motors Club describe devices cutting off after three minutes at 3 kW loads or after 15 to 20 minutes regardless of load. Workarounds such as Camp Mode no longer function.
Tesla is expanding its official Powershare V2L system to more Model 3 and Model Y variants while third-party options lose compatibility.
