Hyundai Ioniq 5 fuel system problems, 2022–2027
276 of the 1,354 complaints owners filed with NHTSA about the Hyundai Ioniq 5 2022–2027 name the fuel system (NHTSA’s “Fuel/Propulsion System” heading — fuel tanks, lines, pumps and injection — and on an EV, the propulsion battery and motors). The loudest years: 2022 (89), 2025 (69), 2023 (67). Filed under the same heading across these years: 3 manufacturer bulletins. Every figure is a linked federal record; none is a failure rate, none a repair cost, and none a verdict on one car.
Hyundai Ioniq 5 fuel system problems by model year

Two things the counts carry that are not the car: how many of each year were sold, and how long each has been on the road — an older year out-counts a newer one before anything is wrong with it. The share column is the honest comparison across years: what part of that year’s complaints named the fuel system. Nothing here is a rate.

Common questions
Source: NHTSA complaint database, recalls and manufacturer communicationsWhich Hyundai Ioniq 5 years have the most fuel system complaints?
2022, 89; 2025, 69; 2023, 67. Raw counts, and an older year has had longer to collect them; by share of each year's own complaints the loudest is the 2024 (23%).
Is there a recall for the fuel system on the Hyundai Ioniq 5?
No recall campaign is filed under this heading on any of these model years. A bulletin is not a recall: it carries no federal duty to repair for free.
When do fuel system problems show up on the Hyundai Ioniq 5?
Too few of the complaints carry an odometer reading to say.
What does NHTSA's "Fuel/Propulsion System" heading cover?
Fuel tanks, lines, pumps and injection — and on an EV, the propulsion battery and motors. Owners choose the heading when they file, so it says which area of the vehicle the complaint is about, not which part failed.
