NHTSA has received 25 owner complaints about the 2026 Hyundai Ioniq 5, or 25.0 per year on the road — fewer complaints than typical (complaint index 0.62, where 1.00 is the average of all tracked vehicles). Among the 73 model-year 2026 vehicles we track, it ranks #51 of 73 by complaints per year (#1 = fewest). Against other Hyundai models its rate is 54% lower; against other Electric vehicles it is 51% lower.
Counts are normalized by time on the road, not by sales volume: a popular model generates more reports than a rare one, and complaints are not verified individually. How we count
Limited data: fewer than 30 complaints, so shares and indexes are unstable.
Complaints filed between 2025-12-11 and 2026-10-08. Median delay from incident to filing: 4 days.
