On the 2020-2024 Kia Ray, in April 2026, Korea's Ministry of Land, Infrastructure and Transport (MOLIT) announced a recall of 220,059 Kia Ray vehicles built between December 5, 2019 and August 8, 2025 — the largest single recall in that announcement batch. The engine control unit (ECU) software was found to be inadequately designed, creating a risk that the 1.0L Kappa engine shuts off unexpectedly while the car is being driven. A stall in traffic disables power-assisted systems and creates a collision risk, which is why MOLIT classified it as a safety defect. Corrective action (free ECU reprogramming at Kia service centers) began March 28, 2026.
Common Symptoms
Engine suddenly shuts off while driving
Loss of throttle response before the stall
Power steering and brake assist feel heavy after stall
Warning lights illuminate when the engine cuts out
Engine restarts normally after the stall
How to Fix
Have the recall performed free of charge at any Kia service center or Auto-Q shop: the ECU software is updated (reprogrammed) to the corrected calibration. Owners can check whether their VIN is included at the Korean automobile recall center (car.go.kr). Owners who paid out of pocket for related repairs before the recall can claim reimbursement from Kia.

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.
