What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2026 Kia Niro, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
Driving through intersection making a left turn and a driver blew the light at 45-50 (speed limit is 45 on road) t-boned the vehicle. Air bags did not go off even hitting the zone on the car front passenger door. I have pictures and police report if needed. I contacted Kia and haven’t heard back. This was a rental car through Dollar Rental at Orlando Intl Airport. It was not drivable.

Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
Falsification and/or alteration of repair logs, service dates, and/or mileage records across dealership diagnostic networks and third parties. Evasion of warranty and/or other maintenance requirements. Poor dealership and corporate treatment/harassment of military veterans. Suspected unauthorized non-factory wiring harness splices and/or other devices tapped directly into primary Controller Area Network (CAN-Bus) control modules on current model-year (2026) passenger vehicles; resulting in inconvenient and unsafe intermittent faults including potential thermal runaway/fire hazard, other potential safety hazards, severe mental distress, and time/financial losses. Real time telematics updates when parked ultimately resulted in total loss of vehicle, likely due to logic induced parasitic 12v battery drain from previously mentioned unauthorized aftermarket devices. Second ("new") vehicle from the same lot shows similar symptoms and contradicting Carfax reports. Parked pending investigations.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
