Hyundai Ioniq I recalls: manufacturer campaigns

Is your version affected?

Find your engine (fuel type and power on the registration document): each row lists the campaigns that concern it. A recall often covers only a production period: only the vehicle identification number (VIN) settles it.

Each campaign in detail

1. Recall: power relay under the rear seat (hybrids)

   Manufacturer recall

   NHTSA recall 18V-704: the main relay of the Power Relay Assembly, located under the rear bench, can have poor contacts and overheat, with a risk of fire. Mainly concerns 2017-2018 hybrid Ioniqs and some 2018 plug-in models. The recall was reopened in 2022 (22V-459) because the correct remedy had not always been applied. US campaigns: have the serial number checked with Hyundai France.

   Fixed free of charge by a dealer and not counted in the reliability score: ask for proof the work was done (invoice, or a VIN check at a dealer).

2. Recall: coolant in the EPCU (electric 2016-2017)

   Manufacturer recall

   Recall 17V-532: the aluminium housing of the Ioniq Electric's power control unit can have porosity allowing coolant to reach the circuit board, with a risk of power loss at high speed. Transport Canada specifies that hybrids are not affected. Production from November 2016 to March 2017 according to NHTSA.

3. Recall: high-voltage battery (electric)

   Manufacturer recall

   Recalls concern the high-voltage battery of the electric Ioniq for a risk of internal short circuit or thermal instability that could cause a fire. In 2021 Transport Canada asked for charging to be limited to 80% before the battery is replaced. A more recent campaign concerns Ioniq EVs built from June 2019 to July 2022, according to a European alert relayed by iautos. Have the campaigns checked using the serial number.
