A member of online community Reddit contacted Nintendo of America customer support about the freezing issue which seems to be affecting quite a few Wii U owners. The customer service representative told the individual that they were aware of the issue and that there should be a patch coming sometime next week.
“I called about my Wii U locking up at random and the lady surprised me when she said that I should wait until next week to apply the new system update that should fix the issue and if it does not then I should call back and do further troubleshooting. So I asked her “are you telling me that there will be a update for the Wii U next week that will fix these freezing issues?” and she again said that there would be an update and it would likely fix my problem. The only other info she asked of my was what color the system was (so they can keep track of basic vs deluxe console issues I assume) and what game I was playing when it was freezing.”
“So there you have it, get ready for another patch and cross your fingers it doesn’t take longer than a week.”
