Yeah, we have a CX-3 too, and been reliable, not a single repair. Only complaint is that once in a while the blind spot monitor thinks something is there that isn’t.
Had a Protege 5 that had no issues at all either.
Had a Mazdaspeed Protege that had issues with pretty much everything that made it a Mazdaspeed, but that wasn’t developed by Mazda themselves, and was low volume for US only, so I don’t take that as being representative.
