Kia Motors America is recalling certain 2017-2018 Kia Niro hybrid electric vehicles previously affected under recall 18V-666. The Main Relay within the Power Relay Assembly (PRA) may have inadequate connections between its contacts, causing increased electrical resistance, which can overheat the rear seats.

The potential number of units affected is 27,030.

Dealers will inspect the PRA and replace either the PRA or the Main Relay, as necessary, free of charge. Owner notification letters are expected to be mailed Jan. 9, 2023. Kia’s number for this recall is SC256. This recall supersedes NHTSA recall number 18V-666.
