2026 Hyundai Ioniq 9

Too new to assess

The 2026 Hyundai Ioniq 9 is too new for this measure. Almost every complaint about a vehicle this recent is a first-year complaint, because that is all the service life there has been, so the figure cannot separate a genuine early defect from simple youth. The complaint counts, systems and recalls below still stand on their own. The most-reported system is electrical system (19 complaints), typically at 7 mo.

Complaints: 60
Median age at failure: 8 mo
Median mileage: 12,000 n=1
Crash / fire / tow: 8.3% of reports
Safety recalls: 3

Seats:mid/rear assembly:power adjust

Hyundai Motor America (Hyundai) is recalling certain 2026 Ioniq 9 vehicles equipped with a Limited, Calligraphy, or Calligraphy Design trim package. The second-row power seats may fail to detect a person. As a result, the seats may continue to move after contacting a person during powered seat functions, such as automatic power fold-and-stow.

A person, especially a child, may become trapped by a rear powered seat, increasing the risk of injury.

Suspension:critical fasteners

Hyundai Motor America (Hyundai) is recalling certain 2025 Ioniq 5 and 2026 Ioniq 9 vehicles. The fasteners for the rear suspension may loosen and detach, which can result in a loss of vehicle control.

A loss of vehicle control increases the risk of a crash.

Electrical system:propulsion system:traction battery

Hyundai Motor America (Hyundai) is recalling certain 2025-2026 IONIQ 5 and 2026 IONIQ 9 vehicles. The high voltage battery system may contain an improperly tightened bus bar, which can cause a short-circuit.

An electrical short in the high voltage battery system increases the risk of a fire.

Electrical system mileage not reported 3 mo in service

The Integrated Charge Controller Unit (ICCU) failed at 7622 miles, causing the pyrotechnic fuse to fail as well. The vehicle was towed to the nearest Hyundai dealer. Repairs took 2 and 1/2 weeks due to parts availability. My wife, who was driving at the time, could have been stranded. Fortunately, the failure occurred close to our home. The dealer did confirm the fault code and failure of the ICCU and fuse. Warning messages appeared AFTER the failure, not before, including one sent to my phone a day later.

Electrical system mileage not reported 6 mo in service

Suspected ICCU failure. Progressed rapidly to car being immobile. Known issue not being addressed by Hyundai.

Electrical system mileage not reported 7 mo in service

Vehicle was operating perfect then got alert indicating electrical system fault but vehicle still drove (was just 2 miles from home ) but then alarms sounded and just able to pull off road before vehicle died. Checked and see code DTC PIA9096 and car was inoperable after. Towed to dealer for replacement of ICCU module. They acknowledged they have seen this before. I was on a local road, but if this happened on a highway, would have been more hazardous!

How to read this

This is what owners reported, not a reliability rating. People file with NHTSA about alarming failures, not routine ones, and complaint volume tracks how many cars were sold.
Failure ages come from the incident date on each complaint, populated on about 83% of records. Mileage is shown where reported — NHTSA’s 2021 system change cut mileage capture to roughly 15%, so it thins out sharply after MY2020.
Every rank compares this vehicle only against others of the same model year. A 2025 car has not had time to accumulate five-year failures, so comparing early-failure share across years is meaningless.
Fourteen make-months distorted by media storms and mass recalls — Toyota in February 2010 ran 11× normal volume across 33 models — are excluded.
Recalls are manufacturer actions and authoritative; complaints are not. A recall listed here may already have been performed on any individual car. Check a specific VIN at nhtsa.gov/recalls.
