## What is wrong

Hyundai Motor America \(Hyundai\) is recalling certain 2017\-2018 Hyundai Ioniq Hybrid and 2018 Ioniq Plug\-In Hybrid vehicles.   The Main Relay within the Power Relay Assembly \(PRA\) may have inadequate connections between its contacts, causing increased electrical resistance.


## What can happen

The increased electrical resistance can overheat the rear seat which is above the PRA, increasing the risk of a fire.


## The remedy

Hyundai 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 began February 28, 2019.  Owners may contact Hyundai customer service at 1\-855\-371\-9460.  Hyundai's number for this recall is 178.
