The defect

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.
