The game files for Forza Horizon 6 leaked online on May 11, before the official release. The leak is believed to have originated from a user using a token dumper, possibly a reviewer. Playground Games, the developer, denied any involvement and clarified that the leak was not due to a preload issue. Players who purchased the Deluxe Edition are unable to preload the game ahead of its launch on May 19. Playground Games is enforcing strict actions against those accessing the leaked build, including potential bans. Some players are posting reviews based on the leak, while repackers are sharing versions of the game on forums. TechPowerUp is conducting a performance review of Forza Horizon 6, with results to be published on May 14.
