Hyundai says a power rear seat in the Ioniq 9 can trap a child

Hyundai Motor America has recalled 5,360 model-year 2026 Ioniq 9 electric SUVs because the second-row power seats may fail to detect a person, and in the company’s own filing, a person, especially a child, may become trapped by a rear powered seat. The recall covers three trims: the Limited, the Calligraphy and the Calligraphy Design.

The campaign arrives about six months after a two-year-old died in Ohio when a power-folding rear seat in a Hyundai Palisade closed on her. Hyundai’s report on the Ioniq 9 says the company knows of five consumer complaints, two of them alleging minor injuries, and of no crashes or fires in the United States as of its decision date.

Seat logic that does not register contact

NHTSA lists the campaign as 26V588 and files it under the component heading for power-adjust mid and rear seat assemblies. Hyundai’s Part 573 safety recall report gives the root cause in one sentence: current second-row power seat logic may not detect contact with an occupant or object as intended. The report singles out the automatic power-folding function that stows the seat, where a passenger or a child standing beside the seatback is least able to react.

Hyundai lists the estimated defect rate as 100 percent of the 5,360 units, meaning every SUV in the population is treated as carrying the fault rather than a sampled fraction. Those vehicles were built between March 17, 2025, and May 4, 2026.

The related Palisade acknowledgment shows what kind of movements are at issue. NHTSA describes powered functions such as tilt-and-slide and automatic fold-and-stow, operations a passenger starts with a button or a one-touch command rather than by hand. A seat that runs under motor power and keeps moving after it touches a limb, a seat belt or a child leaves the person caught between the cushion or backrest and the cabin structure, which is the entrapment hazard the Ioniq 9 filing describes in its consequence statement.

Biomechanical testing behind the Ioniq 9 filing

Unlike the Palisade, where a recall followed a fatality, the Ioniq 9 filing describes a testing discovery. Hyundai’s Safety Testing and Investigation Laboratory and a third-party engineering firm ran benchmarking and biomechanical testing between March and August 2026, and the report says that work revealed excessive force measurements in second-row seat systems. In plain terms, the seats pushed harder against a test body than they should have before stopping.

The timeline overlaps the Palisade recall. NHTSA’s acknowledgment of recall 26V160 covers 61,093 Palisades and states that the second and third row power seats may continue to move after contacting a person, creating a risk of trapping children and adults. The agency’s letter also lists the interim advice for those owners: avoid rear power seat functions and keep children out of the rear seating area while the seats fold.

Reporting by Carscoops placed the Palisade death on March 7, 2026, said Hyundai issued a stop-sale on the affected Palisades in the United States and Canada, and quoted the company offering its deepest sympathies to the child’s family. A permanent Palisade remedy was still in development when that report ran.

The software remedy and the November owner letters

The Ioniq 9 remedy is a software update to the rear seat control logic, delivered either over the air or at a dealer, at no cost to the owner. Hyundai’s report lists the remedy as implemented on September 3, 2026. According to NHTSA’s acknowledgment letter for 26V588, vehicle identification numbers became searchable on September 12, and owner notification letters are expected on November 9, 2026.

Until the update reaches a given SUV, the guidance is direct. The acknowledgment letter says children are advised not to be in the rear seats or near the rear seating area during power-folding operation, and the NHTSA record tells customers to avoid rear seat power functions until the vehicle is repaired. Nothing in the filing restricts driving the SUV itself.

Hyundai Motor America, the filer, is the only body that has said the Ioniq 9 seats are defective; NHTSA’s role in this case is to record the campaign, publish the VIN lookup and check that the remedy is free and effective. The agency’s recall page states that manufacturers must repair, replace, refund or in rare cases repurchase a recalled vehicle at no cost to the owner, so an Ioniq 9 owner has no reason to pay a dealer for the seat update.

Owners who want to confirm whether a specific Ioniq 9 is included can enter the 17-character VIN at NHTSA’s recall lookup. Hyundai’s customer service line for the recall is 1-855-371-9460, and NHTSA’s vehicle safety hotline is 1-888-327-4236.

The unresolved number is the gap between that September 3 remedy date and the November 9 owner letters, a stretch of roughly two months in which the fix exists on paper but the people with children in the second row have only the interim warning to rely on.
