PlayStation®4 system software update 10.50 and PlayStation®5 system software update 23.01-07.00.00, released on March 8, 2023 included connectivity repairs for the Logitech® G G923 Racing Wheel (G923). Therefore, the GT923 should now function properly, although certain users may experience some differences in the force feedback and vibration effects.

In Gran Turismo 7, the force feedback effects are outputted using the G923’s TRUEFORCE function to replicate car engine vibrations and wheel slip vibrations. If you experience any excessive or loud vibrations, adjust the in-game settings from 'Options'> ‘Controllers’>’Vibration Function’ and change the "Vibration Strength" to your preferred setting. (Vibration Strength is set to 100 by default.)

Also, it's possible to check the inputs of the connected steering controller and calibrate the sensitivity of the pedals from ‘Options’ > ‘Controllers’ > ‘Steering Controller Settings.’

If you continue to experience issues, then disconnect the steering controller entirely and reconnect it to the console.
