The wheel works fine on PC with the gte challenge rim but on the Xbox one it has full button function but no pedal or steering input. Any one else have this problem?
Check here: http://forums.forza.net/turn10_topics65_Hardware-and-Peripherals.aspx There are several threads regarding the wheel in there.
Did you try turning the wheel off(hold guide) then turn back on. I have had ‘dead’ pedals happen to me also and a wheel re-boot fixes it.
