NEW YORK -- Masahiro Moro takes the helm of Mazda North American Operations at a critical time. The product portfolio is fresh and stocked with well-timed crossovers. But profits have stagnated, and 2016 sales are off steeply. The automaker also has some of the lowest loyalty rates in the industry -- 39 percent vs. the industry average of 53 percent, according to IHS Automotive.
