Hello, I have had this problem with my Wii U Gamepad since April. It appears that the left stick has been stuck moving up, and it looks normal on the outside. It just started to do this frequently, and overtime the problem has grown worse. I have tried things, like pressing a, b, -, + at one time, but it seems to change the direction that the left stick is pointing. I also asked nintendo about the situation, but they have not replied (I sent the email 2 months ago). My warranty is also void, Walmart gave me the incorrect plan. Please help me!
