severe NHTSA 19V109000 19/02/2019

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.

Is an extended warranty worth it on a 2018 Kia Sedona?

Math is straightforward: a quality service contract runs $1,800–3,500 over 3 years. With 46 complaints on file and the costliest repair averaging $3,100, one major failure more than pays for it. The catch is reading the contract — many providers exclude wear items and require pre-authorization, so cheaper plans aren't always better value.
