The problem
Kia Motors America (Kia) is recalling certain 2017-2018 Kia Niro hybrid electric vehicles previously recalled 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 risk
Overheated rear seats increase the risk of a fire.
The fix
Dealers will inspect the PRA and replace either the PRA or the Main Relay, as necessary, free of charge. Owner notification letters were mailed January 9, 2023. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC256. This recall supersedes NHTSA recall number 18V-666. Vehicles already repaired under the previous recall will need to have the new remedy completed.
