Known issues on the 2023 K5. Three recalls are on federal record for this model year. The first covers the gasoline fuel system: a damaged check valve can allow air to enter the fuel tank, causing it to expand and contact hot exhaust components, and a melted fuel tank can leak, increasing the risk of a fire. The second covers the automatic transmission, whose fail-safe limited-mobility drive mode may be impaired; the resulting loss of drive power increases the risk of a crash. The third covers the side curtain air bags, which may have been installed incorrectly, causing them not to deploy properly in the event of a crash and raising the risk of injury. Owners have filed 136 complaints for the year and Kia has issued 68 technical service bulletins.

From tracing a fuel-system fault to checking how the side curtain air bags were installed or working through a scheduled service interval, it keeps you on the OEM procedure and the correct specification for your specific 2023 K5.
