The lawsuit alleges that the Joy-Con controllers for the Nintendo Switch platform are defective and have a tendency to “drift,” or input movement commands from the joysticks to the console without input from the user.
The Nintendo Switch console launched worldwide on March 3, 2017, and it sold an estimated 330,637 units in Japan within three days of its launch.
Nintendo will also release the Nintendo Switch Lite handheld system on September 20.
The lawsuit lists complaints from users of the console from many websites, and notes the personal experiences of the lawsuit’s lead plaintiff.
