NHTSA overall safety rating
Not ratedNHTSA has no overall rating for this year
NHTSA's VIN data lists these trims for the 2020 Ioniq. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 31 complaints with NHTSA about the 2020 Ioniq. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 1 recall campaign for the 2020 Ioniq over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Hyundai Motor America (Hyundai) is recalling certain 2019-2020 Kona Electric and 2020 Ioniq Electric vehicles. The lithium-ion (Li-ion) battery may short-circuit.
Risk: An electrical short in the Li-ion battery increases the risk of a fire.
Remedy: Owners are advised to park their vehicles outside and away from structures until the interim action is complete. Hyundai will notify owners, and as an interim action, owners have the option to follow provided instructions to perform a battery update through the vehicle's infotainment system or request a Hyundai dealer to provide the update. Once parts are available, dealers will inspect the Battery System Assembly (BSA), and replace it if necessary. Repairs will be performed free of charge. Owners were notified of the safety risk, and the interim action, with a letter mailed April 9, 2021. Final owner notification letters were mailed June 17, 2021. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 200.
Carmakers sent NHTSA 55 service bulletins and notices that cover the 2020 Ioniq, the latest on Oct 8, 2026. They tell dealers how to fix known issues.
The parts they mention most: electrical system (25), equipment (10), steering (8), engine and engine cooling (6), fuel/propulsion system (5).
NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
