Kia Sedona engine failure problems

Filed Oct 8, 2026 · Engine · OH

In January 2026, I brought my vehicle to a Kia dealership specifically complaining that it was "burning oil." The dealership documented this exact complaint on the invoice, but only repaired external leaks. They failed to perform an oil consumption test, failed to diagnose the internal burning issue, and failed to warn me of any ongoing risk. Approximately four months later, while 400 miles from home en route to vacation and with no warning lights appearing, the engine suffered catastrophic oil starvation and seized. Forced to pay out of pocket for towing, emergency logistics, and an immediate replacement vehicle to continue the trip. An out-of-pocket engine teardown confirmed the internal failure, and my extended warranty denied coverage due to the low oil condition.

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.

In XXX, my 2014 Kia Sedona suffered a catastrophic internal engine failure matching the known 3.3L Lambda V6 factory defect. The engine block threads stripped out, destroying the head gasket and causing extreme, immediate loss of radiator fluid and over-pressurization of the coolant expansion tank. A professional mechanic provided an engine replacement estimate of $16,000, which exceeded the vehicle value. To mitigate damages, the vehicle was salvaged at [XXX] on XXX. On XX, Kia America Customer Care (Case #XXX) formally issued a written denial of warranty coverage, claiming my VIN is excluded from Campaign [XXX] despite the vehicle experiencing the exact failure parameters covered under the factory extended engine warranty.

on 8/6/26 my wife was driving home when the Sedona Van began emitting white smoke and started making a whining noise. Little did we know the head bolts had pulled out of the engine causing the head gasket to blow and coolant to leak and total engine failure. Safety risk was engine could have seized in the middle of my wife driving home which could have caused a sudden crash. Vehicle was taken to dealership which confirmed total engine failure due to the well-documented engine failures of the 3.3L V6 Lamda - II engines. Dealership stated my VIN # was NOT included in the extended warranty that the federal safety agency mandated KIA provide due to this well-documented problem. I was told the extended warranty covered vehicles through 2016 model years, my Sedona is a 2017. Therefore, there was NOTHING they could do. However, this is the SAME issue that has been documented over and over with this engine. But because mine is a 2017 I am being told it is not covered for the total engine replacement by KIA. I was told to call the KIA customer care line which I did. They confirmed my vehicle is NOT covered, but agreed it is the same engine issue that has been seen in the 2013-2016. I was told that I could file a Goodwill case that will be escalated to KIA corporate to see if there is anything they can do to help me. I am now waiting for them to get back to me. I was quoted $13,206 for the engine replacement and likely may need radiator replaced too so probably closer to $15,000 when all done. I am told this is purely mechanical failure and a manufacturer defect. I am waiting for KIA's response but want to file this complaint to see what help is available if they come back and deny covering my engine replacement. simply because it is a 2017. This vehicle has been great so far, has 157,000 well cared for miles until this issue erupted without warning. Dealership said have not seen this on a 2017 Sedona, but it happened, my van is currently dead and will there be more 2017's w/ this issu

2018 Kia Sedona lx stalled while my wife was driving on the highway. No warning lights were on until the vehicle lost all power. Luckily my wife was able to pull the car safely to the side. The vehicle only has 36960 miles. Brought vehicle to the dealer and they said engine was seized. That Kia would not attempt a repair unless I gave copies of oil/oil filters from oil changes that I performed. I did not have these so Kia is not honoring the warranty. I changed the oil every year regardless of the miles. Did not miss. The oil is clean as I just changed the oil a couple months ago. Someone could have been killed. We got that van for our disabled adult son. Thankfully he wasn’t in the vehicle. We’ve been ripped off but at least my family is safe.
