What are the biggest issues with Wii U, PS4, Xbox One?

Troubleshooting service Fixya has released a new report on the issues affecting today's latest game consoles, and the results aren't pretty.
Fixya combed through 40,000 troubleshooting requests shared on its Web site and found that 35 percent of Wii U owners complain of freezing problems, while others are looking for fixes to the GamePad. Another 15 percent of Wii U owners report issues with the console's Internet connection.
Like the Wii U, the Xbox One and PlayStation 4 also suffer from a wide range of troubles. The Xbox One's chief troubleshooting culprit is the Kinect, with 30 percent of users looking for some form of help with the motion-gaming peripheral. The Xbox One turning off was highlighted in 25 percent of posts about the console, but that same problem turned out to be the biggest troubleshooting request from PlayStation 4 owners, coming in at 35 percent of all issues related to Sony's console.
It's worth pointing out that while the issues were in fact tallied on Fixya, the categories are general and do not necessarily indicate a major issue with the consoles. Instead, the data suggests that there are certain tendencies of each console to have trouble in particular areas. That users are questioning certain aspects is also not an indication in every case that they are major issues that could cause any of the consoles to stop working.
