Kia Recalls 21,290 EV9 SUVs as Child Airbag Detection May Fail

A sensor assembly beneath the Kia EV9’s front passenger seat is supposed to help determine whether the occupant is an adult, a child or a child restraint. In 21,290 electric SUVs, that classification process may fail, leaving the passenger airbag active precisely when it should be switched off.

Kia is recalling affected EV9 SUVs from the 2025 and 2026 model years. The company says improper routing within the Occupant Detection System can prevent it from deactivating the front passenger airbag when a child or child seat is present. That condition does not comply with federal occupant-protection requirements because deployment of an active airbag could seriously or fatally injure a child sitting in front.

Why passenger classification matters

An airbag is not simply an on-or-off crash device. Its safe operation depends partly on information about who is occupying the seat. The EV9’s system uses a detection mat and bladder tube to classify the passenger, allowing the vehicle to adjust the airbag’s status for occupants who could be harmed by deployment.

The defect does not mean the airbag will deploy without a crash. It means the system may leave the airbag enabled when a child or child restraint is in the front seat. If deployment then occurs during a collision, the child could be exposed to forces the classification system was designed to prevent.

Kia says it is unaware of any crashes, injuries or deaths associated with this defect. The recall is therefore a response to a documented safety-system noncompliance and potential injury risk, not a report that an EV9 occupant has already been injured by the condition.

Warning signs may not appear consistently

Owners could see an illuminated airbag warning light. Another possible indication is a seatbelt reminder sounding while the front passenger seat is empty. Those symptoms may point to a problem within the passenger-detection system, but the absence of a warning does not establish that an affected vehicle is free of the defect.

Until the recall work is completed, Kia advises owners not to install a child restraint in the front passenger seat. The company also reiterates that children age 13 and younger should travel in the rear. That guidance aligns with National Highway Traffic Safety Administration child-passenger recommendations, which identify the back seat as the safest location for children under 13.

The repair targets hardware and routing

This is not described as a software-only correction. Kia dealers will inspect the Occupant Detection System, replace its detection mat and bladder tube where necessary, and verify that the components are routed correctly. The inspection and any required replacement will be performed at no charge.

The routing requirement is significant because occupant classification depends on a mechanical sensing assembly producing dependable input for the restraint-control system. Correcting only an electronic warning or resetting a control module would not address improperly positioned sensing components. The dealer procedure instead checks the physical parts and their installation.

Kia’s identifier for the campaign is SC379. Owner-notification letters are scheduled to begin mailing on October 20, 2026. Affected vehicle identification numbers were expected to become searchable beginning September 4, 2026, according to the EV9 recall listing. Owners may also contact Kia customer service at 1-800-333-4542.

The campaign illustrates a systems-integration problem with a direct human consequence: the airbag itself may remain available, but the hardware responsible for deciding when it should be suppressed may provide the wrong classification. For affected EV9 families, the immediate boundary is clear keep child restraints out of the front passenger seat until the detection hardware has been inspected and repaired.
