Platform Heritage

The Kia Rio (Korean: 기아 리오) is a subcompact car manufactured by Kia from 1999 to 2023. It was discontinued due to declining popularity and broader economic factors. Body styles have included a three and five-door hatchback and four-door sedan, equipped with inline-four gasoline and diesel engines, and front-wheel drive. The Rio replaced the first generation Pride—a rebadged version of the Ford Festiva—and the Avella, a subcompact sold as a Ford in some markets. A second generation was introduced in 2005 in Europe and in 2006 in North America, sharing its platform with the Hyundai Accent, a subcompact manufactured by its sister Hyundai Motor Company in South Korea. In August 2023, the K3 was introduced as its successor in several markets such as Mexico and the GCC countries.

Vehicle health varies wildly by individual history. Aggregate recall and complaint data cannot tell you whether the specific car on the lot had its monitors cleared or its odometer rolled back. Verify the physical or digital scan before you sign a bill of sale.
