NHTSA investigations into the engine on the Sedona

DP24-002opened Feb 27, 2024
Engine · model years 2016

3.3l engine loss of motive power (lomp). Closed mar 5, 2024.

NHTSA summary
The Office of Defects Investigation (ODI) received a petition on February 20, 2024, requesting the opening of an investigation into an alleged defect of the "engine" on the following vehicle model stated by the petitioner: 2016 Kia Sedona vehicles equipped with the 3.3L V-Shaped GDI Lambda-II engine. The petitioner raised the issue of a Loss of Motive Power. On November 13, 2023, ODI opened PE23-019 to address allegations of loss of motive power, on the 3.3L V6 Lambda-II engine for 2016-2017 Kia Sorento and included the 2016 Kia Sedona as a peer vehicle. This investigation is ongoing and addresses the potential safety-related defect raised by the petitioner. In view of the open Investigation, PE23-019, ODI considers the petition moot and is closing this action. The closing of the petition does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency reserves the right to make that determination at the close of PE23-019.

None of these investigations covers the 2015 model year.

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 it’s using coolant and blowing white smoke. It’s 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.”

“Engine failed at 93k miles. Engine burnt off all oil, even though it had engine oil changed 1,000 miles ago. Sensors did not activate to display error engine codes on the dash. Verified by independent mechanic. Kia Dealership said it was owners failure for not keeping oil in engine. Refused to replace engine. Powertrain is not under warranty as second owner.”

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.
