5/5 Overall
NHTSA 5-Star Safety Rating
Engine complaints dominate the 2015 Sedona's complaint picture, with owners frequently reporting sudden stalling, complete power loss while driving, and catastrophic engine failure, often with no warning lights beforehand. A recurring theme is oil consumption severe enough to damage the engine without triggering any alerts, leaving owners unaware until failure occurs. Overheating is also common, with several owners reporting coolant temperature spikes that led to diagnoses of cracked head gaskets or water pump issues, typically resulting in a recommendation to replace the engine entirely. Electrical system complaints are the second-largest category, followed by exterior lighting issues. The engine failures tend to show up at higher mileage but without the gradual symptoms owners might expect, stalling in traffic and sudden high-pitched squealing at engine failure are among the more commonly described experiences.

With Injuries
By System
The 2015 Kia Sedona has 7 recalls, the most serious involving the front passenger airbag, which can deploy in a crash even when an infant or child is seated there because the wiring that detects seat occupancy can break over time.
This occupant detection wiring issue only affects vehicles with a manually-adjusted front passenger seat. On the sliding door side, the power sliding door may not reverse when something blocks it while closing, which can cause injury to an occupant caught in the doorway. These two issues are covered across multiple recalls but describe the same underlying defects.
There is also a turn signal problem where the junction box software can misread the signal stalk and activate the opposite turn signal from what the driver intends, showing left when the driver signals right or vice versa. On vehicles equipped with an accessory trailer wiring harness, water can get into the control module, short it out, and cut power to the trailer lights, making the trailer less visible to drivers behind and masking braking and turning signals.
At a glance
What can fail
The trailer wiring harness may allow water to leak into the control module, causing a short circuit that disables trailer lights.
What the fix does
Dealers will inspect the harness and replace it if it's from the affected batch. Always verify trailer lights work before towing.

What can fail
The wiring for the Occupant Detection System can break on certain vehicles with manual front-passenger seats. If it breaks, the airbag won't disable when an infant or child sits in the front passenger seat.
What the fix does
A dealer will remove a wiring harness clip to prevent the wire from breaking. If the wiring is already damaged, the front passenger seat cushion will be replaced.
