2017 Kia Sedona engine problems

“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 NHTSA 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…”

“The contact owns a 2017 Kia Sedona. The contact stated that while driving at 55 MPH, the contact the oil light illuminated, and the vehicle decelerated independently. The contact mention he pulled over to the right side of the road, exited the vehicle and when he lifted the hood of the vehicle, he noticed flames coming from the engine. No injuries were sustained. No medical attention. There was no police report filed. The fire department did not show at the scene to extinguish the fire. The vehicle was not destroyed. The vehicle is currently still at the scene. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 146,658.”

“Same defect on NHTSA (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”

“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…”

“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…”
