Electrical, Body & structure Vehicle recall #18V338000 · 2018 · 106,428 vehicles
What's wrong: The psd May not auto-reverse when its closing is obstructed.
Why it matters: If the door closes on an occupant, there is an increased risk of an injury.
The fix: Kia will notify owners, and dealers will reprogram the psd module software, free of charge. The recall began on June 18, 2018.
Electrical Vehicle recall #19V109000 · 2019 · 94,389 vehicles
What's wrong: Over time, the occupant detection system (ods) wiring harness located underneath the front passenger seat May break from the seat being occupied.
Why it matters: If a child is in a child seat in the front seat, a broken ods wiring harness will not prevent the front passenger air bag from deploying in the event of a crash, increasing the risk of injury to the child.
The fix: Kia will notify owners, and dealers will remove the wire harness clip to prevent the wiring harness from breaking. If the harness is found damaged, the front passenger seat cushion will be replaced. These repairs will be performed free of charge. The recall began March 19, 2019.
Airbags Vehicle recall #22V031000 · 2022 · 410,619 vehicles
What's wrong: The air bag control unit (acu) cover May contact a memory chip on the printed circuit board and damage the electrical circuit. Circuit damage May result in deactivated air bags that will not deploy in a crash.
Why it matters: Air bags that do not deploy as intended can increase the risk of injury in a crash.
The fix: Dealers will inspect the acu, and either update the software or replace the unit, as necessary. Repairs will be performed free of charge. Owner notification letters were mailed March 21, 2022.
