Platform Heritage

The Hyundai Sonata (Korean: 현대 쏘나타) is a mid-size car that has been manufactured by Hyundai since 1985. The first generation Sonata, which was introduced in 1985, was a facelifted version of the Hyundai Stellar with an engine upgrade, and was withdrawn from the market in two years due to poor customer reaction. While the nameplate was originally only sold in South Korea, the second generation of 1988 was widely exported. The Sonata is currently manufactured in South Korea, China, and Pakistan. It was named after the musical term, sonata. It was formerly manufactured in the United States from 2005 until 2022, though after 2022, American production was phased out.

  4. Run a MotoMetrics on-site scan for Hyundai Sonata before signing the bill of sale.

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.
