5: Infiniti J30
The Infiniti J30 was another sedan that Infiniti rushed to the market. The problem with the J30 was that it was smaller than the competition. The cramped interior didn’t bode well with shoppers who were in the market for a luxury sedan. The single engine choice was also a drawback when there were smoother options on the road, like the ES300 (via Hooniverse).

Another problem with the J30 was the rear-end, which had a humped design. The end result was a sedan that lacked the cohesive styling you’d expect. Likewise, the performance of the J30 was also lacking. In the luxury car segment, performance is one of the main selling factors and the J30 was lacking.
