2016 Kia Sedona

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.

While driving my van I had stopped to put car in reverse to park and as I was putting van back into drive to finish parking the engine quit, I was unable to restart the vehicle, just a click sound. All the lights doors everything electric worked, still purchased a new battery in case that was the issue. There were no service engine lights, oil lights or any other warning signal on the dash. My brother assisted me and checked my oil which was depleted and gummy on the tip. I reached out to a mechanic to see about an engine replacement and after telling him the issue stated I should check with Kia because there has been some issues noted with that particular engine, I have reached out to my local Kia dealership Dutch Miller in barboursville WV, however there is no answer and I’ve left two voicemails and still have heard nothing back from them. From my research for engines it stated there was issue with the oil leaking into the coolant without any indications or lights warning due to head bolts loosening over time which was a manufactured part issue, I saw also there was a campaign concerning this and wanted to include my problems with your agency.

I purchased the minivan as a used car last year and I noticed that the airbag light turned on when a passenger would sit on the front passenger seat. I tried to get a diagnosis ever since but many shops that I brought my minivan to didn’t work with airbags. So I eventually brought my minivan to a Kia dealership, Luther Bloomington Kia in Bloomington, Minnesota, and got 2 diagnostics: the first one was on 7/9/26, and the second one was on 8/26/26. Both diagnostics found and confirmed that there is an issue with the occupant seat detector or ocs mat defect, code B149000 dtc (occupant classification system). This matches the Kia recall SC175. This issue is a serious safety concern because the airbag system might not work as it should in the event of a crash. The problem is that the dealership would not repair the issue after diagnosing it without me having to pay for the repairs at my own expense, which by the way I was charged by the dealership for the initial diagnosis. The reason they gave me for that decision is that the issue was already allegedly fixed before I took ownership of the vehicle. They advised me to contact Kia America or Kia Customer Care and ask them to consider authorizing the repair. When I contacted Kia Customer Care, they said that they would not authorize the repairs because my vehicle is out of warranty and that the cost of repairs would be on myself. I asked to speak with a supervisor and they said that there was another way to request a consideration. I later learned that the consideration is called something goodwill. After Kia’s review, I was recently informed that they denied me assistance through goodwill. I requested a denial letter from both the dealership and Kia Customer Care. I have not heard from the dealership at this moment and Kia Customer Care answered my request with an email that said that I would need to get the letter through the dealer, that they don’t give out denial letters. So I decided to escalate this issue to NHTSA.

2016 Kia Sedona with power sliding doors. Both rear power sliding doors fail to completely latch upon closing. Doors make loud clicking sounds while attempting to close and require manual pushing to latch. Kia of Attleboro diagnosed and confirmed in writing that both rear door roller arm assemblies are completely missing the roller, and that this condition is contributing to the latching failure. Both power sliding door motors and rear door latches also need replacement. This is a safety hazard as the doors may appear closed but are not fully latched, posing a serious risk of doors opening while driving, particularly with children as passengers. The condition has been confirmed in writing by a Kia dealership. Kia Motors America issued Warranty Bulletin WTY019 in March 2021 specifically extending coverage for this exact latching condition on 2015-2017 Sedona vehicles to 15 years/unlimited miles. The covered components (motors and latches) have been approved for warranty replacement. However, Kia America has denied coverage for the roller arm assemblies despite their own dealer's written confirmation that these parts are directly contributing to the covered latching failure. Components are available for inspection upon request. No warning lamps appeared prior to failure. Problem developed gradually with increasing noise before doors failed to latch completely.

Engine experienced mass, sudden oil consumption with no warning of any sort, resulting in significant engine damage. Oil had been changed apx 800 miles prior to incident, and vehicle showed no signs of leaks or oil consumption following the oil change. No oil leaks or wetness were found around oil filter or drain plug. Vehicle drove perfectly fine one day, and when started to leave a store it began horrendously knocking, despite operating as normal on the drive to the store. Dipstick was completely dry. No engine warning light was triggered, no low oil warning, etc. I contacted Kia America directly, as I had found examples of this same issue reported online and hoped for some cooperation, and was given a generic response to haul it to the nearest Kia dealership for diagnosis and repair, out of my own pocket.
