2017 Kia Sedona engine problems

Filed Aug 17, 2026 · Engine · NY

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

Same defect on the federal safety agency (Investigation PE23-019) my vehicle is 1 month outside of the manufacturing date listed, having the same issues, but they will not cover it-even though the same engine is in it. KIA bulletin WTY039 Vehicle is overheating, coolant is bubbling

There was an unusual amount of oil "slug" created by the engine which caused the engine to be inoperable. Therefore, we had to replace the engine.

My vehicle would not start, after jumping and idling for a few moments, all dash lights started flashing and vehicle wouldnt go into gear. I shut it off as it started making a hum and smelled like something wasnt right. A mobile mechanic who came to my rescue after breaking down did a diagnostic of my engine. I was told I had low to no oil. I asked how was this possible as I had only driven around 2,000 miles since my recent oil change at the KIA dealer ( Wesley Chapel, FL). He said the tech may not have put recommended oil amount or the engine is consuming the oil. I told him I would contact the dealer regarding this matter. Long story, short I broke down to needing a new battery and alternator. I don't know if this was the exact cause of the latter 2 needing to be repaired. However, since speaking to others this is common with some models. I even had 1 individual state there were recalls and engines were being replaced as the engine could potentially lock up or fail. I am not finding a recall. Is this an issue that has been reported and I am missing something. Also, there was a recall on the sliding doors at 1 point. I am still having issues with the drivers side yet tge dealerships want to charge me a diagnostic fee. How do I go about seeing if this is an ongoing issue.

137,000 Miles, regular oil changes every 4,000 miles,even adding 2 quarts during the 4,000 miles it would still come up short by 1 quart. Started throwing p0018 timing code,high pressure fuel pump on front blew off the valve cover,Im assuming due to jumping out of timing,as the high pressure pump sits ontop of one of the Camshaft rollers. Engine started knocking and is now useless.

Vehicle Information: 2017 Kia Sedona VIN: [XXX] Engine: 3.3L GDI Mileage at failure: 186,000 miles Complaint: I am filing this complaint regarding sudden engine failure in my 2017 Kia Sedona equipped with the 3.3L GDI engine. The vehicle had approximately 186,000 miles at the time of failure and had just undergone a routine oil change prior to the incident. While driving on the highway, a warning light illuminated on the dashboard. Shortly after the warning light appeared, the engine began making a loud knocking sound. The knocking rapidly worsened, indicating internal engine damage. The failure occurred while the vehicle was in motion at highway speed, creating a serious safety risk due to potential loss of power and reduced ability to accelerate or maneuver safely. The vehicle was diagnosed as requiring a full engine replacement. The estimated cost provided was $5,758.05 for the engine, plus an additional $1,800 core charge, not including labor costs. This represents a substantial financial burden. It is my understanding that Kia has prior knowledge of widespread issues involving GDI engines, including premature internal bearing failure and engine seizure in multiple models. Despite this knowledge, the 2017 Kia Sedona with the 3.3L GDI engine has not been adequately addressed. Sudden engine failure at highway speeds poses a significant safety hazard and increases the risk of collision. I am requesting that the federal safety agency investigate the 3.3L GDI engine used in the 2017 Kia Sedona for potential manufacturing defects related to premature engine failure and internal component damage. Thanks, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My husband and I originally bought our White 2017 Kia Sedona LX on 9/12/18 from Hertz automotive sales. Since that time we had had no engine issues. We maintained our brakes, and standard upkeeps on the car. Eight years in and still our car had given us no issues. Our most recent oil change was on 9/13/25 and it was inspected during that oil change and no issues were noted. The car had since that time been driven as expected to school for kids and work for myself and activities on the weekend for family time. There was no weird smells, discolored smoke from the tail piper or anything. The car was running fine. At no time were any warning signals on, flashing or intermittently coming on and off. Then on Thursday, 1/22/26 evening I stopped by the gas station to get gas before turning into my neighborhood for home. Upon leaving the gas station, I noticed and felt the engine seemed off and vibrating with soft tremor like shaking and as I pressed on the gas for power it was soft power, and at that moment only did I see the check engine light on solid (not flashing). I called my husband and a few mins later we made it home, he came out to check the car, and saw now that the engine light was flashing over and over. We read up on what this meant and new we had a problem. We dropped the car off on Saturday to the mechanic and on Monday, 1/26/26 a diagnostic was made and was given the bad news that the engine had complete failure. $18,000 bill to fix all the issues. But here is a short synopsis: Multiple codes found in ECM Metal found in oil, oil is also 1 or more quarts low P0300 (Random misfire), P0302 (CYL #2 misfire), p0304, (CYL#4 misfire) p0306. (CYL#6 misfire) p0175, (bank 2 rich) p0018 (crank - cam correlation) Engine has internal failure, failing piston rings allowing oil in combustion chamber, causing misfire, rich condition and engine shaking This was a shock and we had to sell it for nothing to a salvage company.

Engine with around 107K miles has had regular maintenance done to it. Went out one morning to start my van and there was a knocking noise coming from under the hood. We then had it towed to an engine/transmission repair shop to have it looked at and was told that we needed a new/used engine and the price was thru the roof. this is a very trusted shop so took there advice. To have the engine replaced is going to cost more than what the vehicle is worth. This is a known issue with some kia engines as they with no signs of failure prior to the noise. We had not one warning light on the dash, it just went poof.
