I picked up the bundle about 2 weeks ago with Mario Kart 8 and the deluxe system. I get random freezes when playing Mario Kart 8 (disc version). When it freezes, it makes a buzzing noise out of the speakers for about 5 seconds and the image of the game is frozen on the screen (TV and gamepad). The game disc can still be ejected and if I hold the power button for about 5 seconds the system will shut down. When I reboot it tells me not to shut down that way because it is out of stand by or something like that. I have had it happen once in Pikmin 3 (download) and once in the Wii U menu.
This has never happened when playing DK Tropical Freeze (disc) for hours on end. Hasn't froze when playing New Super Mario Bros. (download). I have the latest updates and firmware. I would be hard pressed to believe it is a problem with the hardware as I have played DK for hours without problems.
Anybody else with these problems?
