Car won't stop accelerating

@merelmonster Hey, it sounds like your system is trying to use multiple inputs at once. Can you try unplugging any other USB devices from your account, then try to play with just the Keyboard & Mouse?

Thanks, please let us know how you get on. 

i tried that, it did not help.
i even tried unplugging my mouse and keyboard aswel,, yet the car still keeps accelerating

@merelmonster Huh, that's interesting, maybe there's a software reason for the ghost input. 

Can you try restarting your system with a Clean Boot and see if this has any effect?

When i restart my pc and the game without the controller attached to it, it works fine for a few minutes.
i can just attach my controller and do some race, but after a while the problem just returns, and i cant control my car anymore, Even when i detach the controller again.

I also tried a different controller, yet still the problem returns.

That's very odd indeed. I wonder if disabling the device will help...

If you go to Control Panel > Device manager there should be a section for gamepads. When you encounter the issue next, can you try disabling the pads here and see if that affects things. 

I'd also try entering another game and see if that is also affected.
