What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2027 Hyundai Ioniq 5, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
ICCU failure after owning this brand new car for 14 hours. Odometer was under 200 miles when it failed and became inoperable. Hyundai has not fixed this ICCU problem and should be prohibited from selling these cars until the issue is fixed. The past recalls don’t cover 2026 or 2027 model years, but obviously this is still a major problem
