Hyundai Ioniq Recalls

The Hyundai IONIQ has 13 recalls covering 2017–2020 model years, with the most serious being a 2020 Electric variant where the lithium-ion battery can short-circuit internally and start a fire.

The 2019–2020 model years have two separate wheel lug nut recalls: on 2019 PHEV models, lug nuts were not fully tightened at the factory and can loosen or fall off entirely, and on 2019 Hybrid models, the right rear wheel specifically may not have been tightened sufficiently, in both cases allowing a wheel to detach while driving. The 2017–2019 Electric models share an issue where an unstable electrical ground can push the vehicle into a reduced-power fail-safe mode, and under certain conditions in that mode the car can continue accelerating after the driver lifts off the accelerator pedal.

The 2017–2018 Hybrid and Plug-In Hybrid models have a recurring fire risk tied to the Power Relay Assembly mounted under the rear seat. The relay contacts can have inadequate connections, which raises electrical resistance, generates heat, and can ignite the area beneath the rear seat. An earlier repair attempt for this issue did not fully resolve the problem, leading to a follow-up recall covering the same 2017–2018 vehicles.

The 2017 model year carries the heaviest concentration of issues. On Electric variants, the housing of the Electronic Power Control Unit can contain internal voids that allow coolant to reach the circuit board, causing the vehicle to stall without warning. On Hybrid models, the hydraulic clutch actuator's inner oil seal can leak, letting oil pool near electrical components and create a short-circuit fire risk. There is also a separate Power Relay Assembly fire concern on 2017 Hybrid and Plug-In Hybrid models tied to the main relay contacts overheating. A compliance-only recall affects 2018 Plug-In Hybrid models sold in Canada, where the vehicle's weight rating label may show incorrect values.
