4. Acura ZDX
Honda’s luxury division Acura is known for elegant cars and quality products. But it’s also known for a strange and pretty ugly model called ZDX. On sale for just three years, the ZDX attempted to present something between a sedan and a crossover SUV. It ended up being neither. Despite a good technical layout and decent power, buyers simply didn’t like the ZDX. Acura managed to sell just 7,200 examples (via MotorBiscuit).
The main reason why the ZDX failed was its design. It was so strange and ugly that most customers decided to stay away although it was a decent car with nice features. However, it became one of the biggest flops that Acura ever had.
