Chosen Solution

When playing games or navigating the Wii U menu, the left stick of BOTH of our Pro Controllers defaults to the left instead of not moving. This means to correct it we have to push in the opposite direction (right) just to go straight in game. It makes menus a nightmare. Also, we never really are ever able to turn right in Mario Kart 8… Please help! We used them for a couple months without any problems before this just happened out of the blue.

First off, have you tried to resync the controllers? Im assuming you know how to do this but if you dont just hold down the sync button on the wii and the controller at the same time and they should link. If that does not help This link here might help http://en-americas-support.nintendo.com/
