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

Two numbers, one recall

Every safety recall carries two identifiers. 178 is the number Hyundai assigned in its own system: it is what appears on the owner letter, on the dealer’s service screen and on the repair order. 18V704000 is the number NHTSA filed the same recall under when the manufacturer reported it, and it is the one every federal record, this site included, is keyed on.

The repair is free by federal law for vehicles up to fifteen years old. Whether one particular vehicle is included is settled by its VIN against the manufacturer’s build list, not by its model year.

Common questions

Source: NHTSA, 49 CFR Part 573

Is 178 the same recall as 18V704000?

Yes. 178 is Hyundai’s own number for it; 18V704000 is NHTSA’s. One recall, two references.

Which vehicles does 178 cover?

2017–2018 Hyundai Ioniq, 10,575 vehicles by the manufacturer’s count. A recall covers a build range, so the VIN decides whether one particular vehicle is in it.

Does the 178 repair cost anything?

No. The manufacturer must remedy a safety defect at no charge for vehicles up to 15 years old from first sale.
