Kia has identified a potential safety issue with certain 2022 Kia Niro Electric Vehicle (EV) models. The problem affects the high-voltage battery safety plug, which may overheat and melt due to electrical resistance.
What Happened?
The issue came to light in July 2023 when a dealer reported a case involving a 2022 Niro EV that shut off while driving without entering “Ready” mode. Further investigation revealed an isolated melted safety plug. Kia’s Safety Office monitored the issue and found no other incidents except for one isolated case.
What Did Kia Find?
Kia’s Safety Office conducted field data analysis and discovered that the melted safety plug was caused by high temperatures, not any issues with the battery cells or temperature sensors. The investigation also revealed a manufacturing process deviation in the supplier’s Female-Female terminal, which affected specific vehicle production lots.
Recall Alert
As a result of the findings, Kia has issued a recall for certain 2022 model year Niro EV vehicles due to the potential safety risk posed by the faulty safety plugs. The recall was announced on May 15, 2024.
If the electrical resistance in the safety plug occurs while driving or during battery charging, it may melt, increasing the risk of:
- Loss of motive power
- Fire
Drivers may notice an illuminated EV Service Warning light and/or a burning smell (melting plastics and smoke).
What to Do?
Owners with affected vehicles are advised not to charge their vehicle in a garage or any other covered structure until the recall repair is completed. Dealers will replace the safety plug, and owner notification letters are expected to be mailed on July 19, 2024.
