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.

Should you keep driving it?

This page can't tell you that. 0 of 29 reports involved a crash and 2 people were hurt. 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.
