Common questions
Source: NHTSA complaint database, recalls and manufacturer communicationsAre fuel system problems common on the 2025 Hyundai Ioniq 5?
They are documented: NHTSA holds 69 owner complaints naming the fuel system on this model year (22% of everything owners filed about it), and 4 manufacturer bulletins are filed under the same heading. Whether it is a problem on one particular car is a diagnosis, not a count, and a count says nothing about how many were sold.
Is there a recall for the fuel system on the 2025 Hyundai Ioniq 5?
No recall campaign is filed under this heading for this model year (there are 9 filed under other headings). A bulletin is not a recall: it carries no federal duty to repair for free.
When do fuel system problems show up on the 2025 Hyundai Ioniq 5?
Too few of the complaints carry an odometer reading to say. The model year's page shows the mileage curve across every system where it can.
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.
