Engine failure on other Sedona years
Report counts are for each model year on its own, so a newer car has had less time to collect them.
What this problem usually is
These are the reports nobody wants to file. The engine started knocking or ticking, the oil light came on, and then it seized or had to be replaced. Some owners had the replacement covered under warranty or an extension, and plenty were told they'd pay. Several narrower sheets split this group into knocking, seized engines and rod bearing failure.
What got replaced
Owners who name the part that was replaced mention the engine (29 reports).

Is this a known problem?
The manufacturer has sent NHTSA 5 service bulletins or notices for the 2015 Kia Sedona that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

What owners wrote
“In 2021 we purchased the van and within hours the motor blew. The car dealer had the motor rebuilt and it has been good until recently. It seems the head gasket is blown as itâs using coolant and blowing white smoke. Itâs also burning oil. This should not happen every couple years”

“Rod failure, was told there was fuel mixing with the oil and caused the oil to break down and cause complete engine failure while driving down the highway with my kids. Kia will not do anything about it. How can this be right. I know a lot of people with the same issues.”

“Engine light came on while in route for an oil change. Walmart automotive changed the oil and checked the light. Read p0014. Engine light went away after oil change. Drove fine for 4 days then went haywire on the interstate. Oil light started flashing then engine light. Lost all power. Had it towed home. It started with a loud knocking noise. Towed to Kia and there are metal fragments in my oil. Engine blown.”

Should you keep driving it?
This page can't tell you that. 0 of 32 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
