2017 Kia Sedona Engine Problems

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.

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.

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 NHTSA 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.

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.

Excessive oil consumption

Oil Control valve failed and oil leaking

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.

I was driving and my engine seized and my car is now undrivable. I immediately looked up recalls and see that there were several recalls and recalls surrounding the engine as well. I am told I now need a brand new engine and was referred to file a report as the issue experienced should not have been happening.

Engine stared clattering at the end of a 2 hour drive home. Engine died entering a round about 1-1/2 miles from home. It restarted and limped to my home. Arranged to have it towed to mechanic shop. They informed me there is issues with rod bearings and that Kia has a class action suite but Kia is telling me that my vin is not involved.

The contact owned a 2017 Kia Sedona. The contact stated that after parking in his driveway, there was white smoke coming from the front of the vehicle. The contact is handicapped and was assisted by his wife to exit the vehicle safely. The vehicle later caught on fire, and flames were visible in the front passenger side that spread to the rear of the vehicle. No warning lights illuminated before or after the failure. The contact stated that the front of the house was damaged, as well as the garage siding, along with an older truck parked in the driveway. The fire was extinguished by the fire department with water, and a police officer was on scene and tried to extinguish the rear with an extinguisher, but was unsuccessful. There was a fire report filed. The vehicle was towed a week after the fire to the insurance tow lot. The vehicle was deemed destroyed by the insurance company. No injuries were sustained. The manufacturer was notified of the failure. The failure mileage was 106,000.

On [XXX], while driving my 2017 Kia Sedona on a road trip through Killeen, Texas, the engine suddenly began making a loud knocking noise without any prior warning, leading to catastrophic engine failure and complete loss of motive power. The vehicle became inoperable and was towed to University Kia in Waco, Texas. The day prior, on [XXX], the vehicle underwent a thorough pre-trip inspection and full synthetic oil change at Sun Auto Tire & Service (5117 Golden Triangle Blvd., Keller, TX 76244), confirming it was roadworthy with no issues detected initially, though oil was found leaking afterward (maintenance records attached). University Kia confirmed the catastrophic engine failure, likely related to the 3.3L Lambda engine's known oil pressure switch (OPS) defects, as the OPS had been previously replaced under warranty. Kia Motors America (Case [XXX]) denied liability unless I pay $3,000 for a teardown inspection to prove the failure was due to the OPS, despite the vehicle's eligibility under the WTY026 extended warranty (15 years/150,000 miles). This failure aligns with similar complaints and NHTSA investigations into 3.3L Lambda engine issues, such as oil starvation and sudden seizures. Due to the failure, we missed a prepaid hotel stay in San Antonio, incurred additional hotel stay charges as our trip had to be extended, and incurred costs for a rental vehicle to complete the trip.

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

Burning through oil faster than it should, needing to feel up oil every week, has been confirmed by an auto repair shop.⁸

I heard a knocking sound in my car which I thought was coming from the engine towards the end of May. It was really bad on May 29, 2025, so I did not drive it again. I called my local dealership and scheduled an appointment for June 2, 2025. The vehicle had to be towed from my house to the dealership as it did not seem safe to drive. The battery had died when I tried to start it, so I called AAA for a tow. They were able to jump start the car, but I still did not feel safe driving it with the loud knocking noise. I had AAA tow my car to the dealership. This is what they found: LOWER ENGINE KNOCK, METAL IN THE OIL, LOWER ROD BEARING FAILURE. No lights were on at the time the severe knocking occurred. How and why was my VIN not included in the recall notice on the engines? This was clearly a safety hazard. This problem SHOULD BE COVERED by the engine recall. Now I have to get a new vehicle with extremely limited funds.

Catalytic converter system failure

Without warning lights coming on my engine started knocking on May 15, 2025. Turns out the bearing between the top of the motor and the bottom of the motor is stripped. 5 months before this happened they replaced the 2 fuel pumps, cvvt, cam shaft sensor and assembly, timing chain and spark plugs. Again I had no warning about that work that the dealership said I needed. Now I need a new motor and they won’t do anything for me except charge over $10,000.

On [XXX] my family and I were on our way to Oklahoma. Luckily we were on a highway instead of interstate when our Kia motor blew. There were no oil warning lights illuminated, nothing. My husband luckily was able to steer the van to the side of the road safely. My vehicle had to be towed and when codes were run on it by the oil changers, NO CODES POPPED UP and there were metal shaving in my oil filter. My husband contacted the dealer, they said the only issue they could find was not a recall, but an extended warranty for an oil pressure switch, but that with it not working it "would not make an engine blow." However, another mechanic said it absolutely would. This van does have the 3.3 engine that has been recalled in other models, but not the 2017. We had to rent a UHAUL to have my van pulled by another vehicle. In the picture you can see all the oil which was lost. How was our safety at risk? We had to pull on the side of the road on a main highway (not interstate), but there wasn't much room between the road side and our vehicle, not to mention the traffic right behind us who could have parked in our trunk when the failure occurred.

Using lots of oil

The Engine failed at 63,758 miles. Lancaster KIA in Lancaster, PA indicated the engine has metal shavings everywhere.

I own a 2017 Kia Sedona with approximately 120,000. It has the 3.3L V6 engine. While driving, the vehicle lost power and would not run. The lights and the dashboard would come on, but it would not turn over to start. I took it to a mechanic, and they confirmed that the engine had seized up and would have to be replaced costing $11,000. I then had it towed to the dealership that I purchased the vehicle. They also confirmed that the engine had seized up and would have to be replaced at a significant cost. I had no warning that anything was wrong with my vehicle as the check engine light did not come on. I did hear a slight knocking the day before this happened. My husband checked the oil and added a quart of oil, which was unusual since we had not seen any oil on our driveway. I did have a warranty, but it lapsed due to being over the mileage cap by 2,000 miles.
