Nintendo has officially ended its Wii repair program in the United States. Additionally, Nintendo will no longer accept Wii consoles for repair in Japan after March 31, 2020. While this may present some worry for owners of older Wiis, it should be noted that the Wii has had few (if any) major hardware problems since its release in 2006.
