2: Mazda 5 (2015)
The Mazda 5 never stood a chance to be a sales success. It was smaller than almost any other minivan on the market, and that market was shrinking. Mazda had never sold a lot of minivans and the 5 was just a victim of this. The small dimensions of the car were no match for Americans.

A fair amount of these models went to rental car lots, and then the model was quietly discontinued in favor of crossovers. The Mazda 5 had a lot of unique potential but it just didn’t fit into the larger scope of the Mazda lineup.
