2021 Kia K4

For almost any modern vehicle category, there’s a Kia that’s worth considering buying. Among small and midsized SUVs, models like the Sportage and Sorento rank near the top in their respective classes for their nice interiors, ride comfort, and appropriately powerful engines. SUVs like the Telluride have ride comfort, interior space, and overall value that earn it regular placement near the top of Consumer Reports’ ratings. Fuel economy across the brand is generally good, but hybrid and plug-in hybrid options are available for even more miles per gallon. Plug-in hybrid options have useful all-electric driving range. Kia EVs are generally competent, ranging from compact sedans up to a three-row SUV. Kia’s reliability scores have been improving, but other brands score higher in our rankings. Specific Kia models have earned our recommendation among used cars.
