I have a 2011 Mazda2 and my wife has a 2016 Scion iA.
There is almost nothing on this board related to supporting the iA.
You can check out scioniaforum.com but am surprised at the lack of technical skill on that site.
People on this board are mechanically skilled while the iA forum discuss dealership maintenance.
Because of this site, I have yet to take my 2 to a garage.
and yes, the iA is a rebadged 2016+ mazda2 sedan.
