4: 2000 Kia Spectra
The Kia brand you see today is nothing close to what it was two decades ago. Kia started out in the U.S. market very lean. The Spectra was one of the first new models introduced to the brand after the Sportage and the Sephia. The Spectra offered great gas mileage and a unique design (via Forbes).

But as with all first model runs, the Spectra had many quality issues from the gate. The car was underpowered and the exterior was not the best looking. The Kia dealership network was also quite small at this time.
