The increased electrical resistance can overheat the rear seat which is above the PRA, increasing the risk of a fire.
Kia Motors America (Kia) is recalling certain 2017-2018 Kia Niro hybrid electric vehicles. The Main Relay within the Power Relay Assembly (PRA) may have inadequate connections between its contacts, causing increased electrical resistance.
Kia will notify owners, and dealers will inspect the Power Relay Assembly (PRA) for damage. If no damage is found, the main relay will be replaced. If damage is found, the PRA will be replaced. These repairs will be performed free of charge. The recall is expected to begin November 23, 2018. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC168.
