Update: I took your advice and called Nintendo. Turns out it was a combo attack: dirty or less than clean screen protector and needing to recalibrate the touch screen. So far, this seems to have fixed the problem.

Thank you for the prompt replies!

So my wife is playing Super Mario U, and blocks start appearing randomly. Keep in mind she's using the Wii remote and I'm NOT playing.
Later, I'm at the home screen and it selects and loads the Mii Maker on its own! Is my system wiggling out? Is the game pad battery low, and features not working affecting gameplay?

Other issues include:
I tried to turn the tv/Wii u off. The tv turned off and the console turned off, but not the game pad (stuck in tv remote mode).
Difficulty selecting anything in Nintendoland when both Wii remote and game pad are up and running.

I bought Gamestop's store warranty (to support those guys, they've been good to me), but I don't want to use it unless I have to. Someone please tell me what's going on!

Hi all, new Wii U owner here (had it about 2 days).
I hope I can contribute as well as get answers to questions here.
GAME ON!
