Hyundai Motor America is recalling 5,360 potentially affected 2026 Hyundai IONIQ 9 electric SUVs in the United States because the second-row power seats may fail to properly detect a person during powered seat operation.
If the detection system does not respond correctly, a powered rear seat may continue moving after contacting someone during functions such as automatic fold-and-stow. That can create a trapping and injury risk, particularly for children.
The campaign is identified by the National Highway Traffic Safety Administration as 26V588000. Hyundai's internal recall number is 307.

What Is Wrong With the IONIQ 9 Power Seats?
The issue involves the powered second-row seating system.
During functions such as automatic power fold-and-stow, the seat system is designed to recognize contact with a person or obstruction and respond appropriately.
On affected vehicles, Hyundai says the second-row power seats may fail to detect a person. As a result, the seat can continue moving even after making contact.
That matters in a three-row family SUV because children and other passengers may frequently be close to the second-row seats while entering, exiting or accessing the third row.
What Is the Safety Risk?
A person could become trapped by a powered rear seat if the system does not detect contact and stop as intended.
The recall specifically notes the increased concern for children.
This is therefore more than a convenience or seat-adjustment issue. The defect affects the behavior of a powered component that can continue moving while a person is in its path.
How Will Hyundai Fix the Recall?
Hyundai's remedy is software-based.
The seat-control software will be inspected and updated as necessary. Depending on the specific vehicle, the remedy may be completed:
- Through an over-the-air software update, or
- At an authorized Hyundai dealership.
The recall repair will be performed free of charge.
When Will Hyundai Notify Owners?
Owner notification letters are expected to begin mailing on or around November 9, 2026.
Owners do not need to wait for a mailed notice before checking their vehicle.
VINs involved in the campaign became searchable through NHTSA's recall system on September 12, 2026.

Where Is the VIN Located?
You can usually find the VIN:
- At the lower driver's side of the windshield
- On the driver's door-jamb certification label
- On the vehicle registration
- On insurance documents
Should Owners Stop Driving the IONIQ 9?
The recall remedy does not instruct owners to stop driving the vehicle.
Instead, Hyundai's guidance focuses specifically on careful operation of the second-row power-seat system until the software repair is completed.
Owners should:
- Keep children away from the rear seating area while powered seats are moving.
- Make sure no passenger or object is in the seat's movement path.
- Avoid relying on the seat-detection function as a substitute for visual supervision.
- Complete the recall remedy as soon as it becomes available for the vehicle.
Why a Software Recall Still Matters
The IONIQ 9 recall is another example of how modern vehicle safety increasingly depends on software controlling physical hardware.
The rear seat is a mechanical component driven by electric motors, but the system's response to an obstruction depends on sensors, electronic controls and software logic.
That is why a software update can sometimes correct a safety defect without replacing the entire seat assembly.
Over-the-air updates can make repairs more convenient, but an OTA remedy should still be treated like any other safety recall: owners should confirm that the required campaign has actually been completed.

DriveSpecLab Take
This is not a massive recall by U.S. market standards, but the potential consequence makes it important.
The IONIQ 9 is designed as a three-row family EV, so powered rear-seat convenience is likely to be used regularly by families accessing the second and third rows.
The good news is that Hyundai's remedy is software-based, free, and may be completed over the air for some vehicles.
For owners, the practical response is straightforward: check the VIN, confirm whether campaign 307 is open, and complete the update as soon as possible.
