Kia Sedona oil consumption problems

Filed Oct 23, 2026 · Engine · VA

Oil consumption is an abnormal rate. Oil needs to be refilled almost every week, and the leak has caused deterioration of spark plugs.

This vehicle has been consuming oil at a fast rate. We have had them do oil consumption tests multiple times and each time they tell us it’s considered normal. They have also told us that an oil warning light would come on if it’s too low, but that has never happened. We have had zero warning lights and have had to constantly monitor the oil level and top it off. We have it serviced regularly by the same place. Now, the oil is burning at a faster rate, after driving 700-800 miles round trip, with full oil, it was on the lowest line on the dipstick and we noticed black marks on the garage floor near the exhaust and have heard sounds. Still no warning lights on. We topped the oil off again and have taken it back to the dealership to assess the problem. I have read online that different Kia models have been recalled for this exact same issue. I have been worried that we would end up with major engine problems because of what’s happening and now that could be the case, or worse, having a fire or something when my kids are in the car. This seems to be an issue for multiple Kia vehicles and I’m not sure why the 2019 Sedona hasn’t been included but that is why I’m making this report.

This vehicle is burning oil at an alarming rate. Between oil changes it has lost 4 quarts before. I constantly have to check and add oil and have experienced stuck pistons and rough idle due to the oil not being at a safe level. Kia service advisors have admitted there have been reports of this happening with this engine, but no recall or inspection has been initiated to my knowledge. They did just issue an optional emission campaign that I completed, but it is unrelated to the oil burn issue.

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.

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.

Engine failure due to loud knocking as a result if high oil consumption. No warning lights ever. Needs replacement. Regular maintenance records available. Original owner with only 63900 miles in less than 10 years. Vehicle supposed to be under powertrain warranty (10 years/ 100000 miles). Kia and dealership keep denying warranty claim despite providing all records to prove regular maintenance.

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.

March 2024 just before hitting 100,000 miles I started having oil consumption issues. Current milage is 137,300 About 10,000 miles ago my check engine light came on. I took it to an auto parts store and it was reading bank 1 O2 sensor. I took it for an oil change and never scheduled for the sensor replacement due to life events. I took it in for another service About 5,000 miles ago. At around 2,000 miles after the service the motor started stalling and sounded horrible. I took it to the dealership and it was 4.5 quarts low on oil. Took it back at 1,200 miles after top off and it was 2.5 quarts low. Started the new motor process which wasn't covered on the extended warranty due to manufactur defect. It cost me 500.00. Before the new motor was in my van started getting me stranded places. Motor wouldn't turn over at all. Got it started went to auto parts store and it was reading 4 bad sensors in bank 1 and 2 (O2 and air intake on the motor). Finally got it to KIA for the new motor told them about they sensors they were supposed to check/replace them when they put the new crate motor in. Picked my van up 3 days ago. I asked when they called if the engine light was off. They called me back several hours later and said yes. Picked it up at 5 pm 3 days ago. By 8am the next morning the engine light was back on. It's scheduled for 9am Monday. The van has now gotten me stranded 2 times in 3 days. Auto parts store ran the computer and the same 4 sensors are still showing bad. Sensors are in bank 1 and 2. The report on the old motor showed cylinder 1 and 2 oil fouling on the spark plugs (replaced at 100,000 miles by dealer) and excessive oil leakage in cylinder 1 and 2 into the crank case due to carbon stuck piston rings. I was told before the motor replacement that the KIA cares warranty may not cover these sensors. Even though the sensors are going out because they are gunked up with 7 quarts of oil their motor used and they didn't go out until the issue started.

Kia service dealer diagnosed high oil consumption on my car with heavy sounds. They recommend to replace whole engine but it's out of warranty. It has only 106k miles on it. I am afraid the car is posing safety issue as well and it has less miles on it. I filed complain with kia consumer corporate a case has been generated on their system [XXX] but no one had contacted me yet.
