What stands out

No new NHTSA electrical complaint has been filed on this vehicle in over 6 years — the issue may be aging out of the active population.
Kia Motors America (Kia) is recalling certain 2015-2018 Sedona vehicles equipped with manually-adjusted front passenger seats
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.
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. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC175.
