On the 2020-2024 Kia Ray, on April 22, 2026, South Korea's automobile recall center published MOLIT's announcement that 220,059 Kia Ray vehicles were being recalled because inadequate engine-control-unit software design could cause the engine to shut off while driving. The corrective action was scheduled to begin April 28, 2026. This indexed page retains its existing 2020-2024 year set; recall applicability must be checked by vehicle or VIN.

Common Symptoms

  • Engine may shut off while driving

How to Fix

Check the vehicle or VIN at South Korea's automobile recall center and have the official Kia recall remedy completed. The primary announcement establishes the defect, population and April 28 start date but does not specify a retail repair part, so no part is linked from this page.

On the 2023-2024 Kia Ray, shortly after the Ray EV's late-2023 relaunch (35.2 kWh LFP battery, 7 kW AC charging), Kia opened a free-repair campaign covering 3,787 vehicles built between September 20, 2023 and January 4, 2024 — effectively every unit sold to that point. When connected to certain slow (AC) chargers, an overcurrent condition can occur inside the integrated charging control unit, illuminating warning lights and preventing the car from charging. Kia is fixing the defect with an improved software update, with the campaign running through August 13, 2026. Separately, early 2023 Ray EVs were reported unable to charge on some older public slow chargers, prompting Korea's Ministry of Environment to publish a list of incompatible charger models.

Common Symptoms

  • Warning light comes on during slow (AC) charging
  • Charging session aborts or never starts on certain public chargers
  • Car charges normally on some chargers but not others
  • Charging error message on the instrument cluster

How to Fix

Have the free service campaign performed at a Kia service center: an improved software update for the integrated charging control unit (campaign deadline August 13, 2026). Until updated, if charging stops with a warning light on a particular charger, retry on a different/newer slow charger, and consult the Ministry of Environment's incompatible-charger notice for chargers to avoid.

Typical repair cost:$0 - $0
