What's wrong?
The Power Relay Assembly on the 2017-2018 Hyundai Ioniq Hybrid and Ioniq Plug-In Hybrid sits under the rear seat. It is part of the hybrid propulsion system, and its main relay switches electrical power through the hybrid system. The relay contacts are the internal points that close the circuit when power needs to flow.
On affected vehicles, the connection between the main relay contacts is loose. A loose contact creates extra resistance instead of a clean electrical path. That resistance creates heat inside the Power Relay Assembly. If the heat builds, the assembly overheats.
The warning sign is an HEV warning light while driving. The vehicle also can fail to start, which means the relay is not completing the electrical path the hybrid system needs.
Who's affected?
Covers both Ioniq Hybrid and Ioniq Plug-In Hybrid versions across the 2017 and 2018 model years, all tied to the same inverter power relay assembly.

| 2017 Hyundai Ioniq Plug-In Hybrid | Inverter |
| Units affected | 10,575 |
A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific hatchback.
What's the safety risk?
An overheated PRA increases the risk of a fire. If the HEV warning light turns on while driving, or the vehicle will not start, treat that as a warning sign and contact a Hyundai dealer before using the vehicle again. Repair is free at any franchised Hyundai dealer.
What should I do?
- Check your VIN to confirm your 2017-2018 Hyundai Ioniq Hybrid or Ioniq Plug-In Hybrid is included in this recall.
- Contact a franchised Hyundai dealer to schedule the free inspection and main relay or Power Relay Assembly replacement.
- Bring the recall notice if Hyundai mailed one, and reference recall number 22V459 when you call.
- Tell the dealer if the vehicle was repaired under recall 18V-704; Hyundai says those vehicles still need this new remedy.
What happens at the repair
At the dealer, a Hyundai technician inspects the main relay or Power Relay Assembly under the rear seat and replaces the part if inspection shows it is needed. Parts and labor are covered under the recall. Vehicles repaired under the earlier 18V-704 recall still need this new remedy completed. If you already paid out of pocket to fix this recall condition, Hyundai's reimbursement plan covers eligible expenses. Bring repair invoices or payment records and ask the service desk how to submit the claim.
