I bought a used 2020 Kia Sorento LX 2.4L in 2022. It had 15,000 miles on it. AT 50,000 miles I noticed it was consuming oil. I have been changing the oil at 5,000 mile intervals even though the manual calls out to do it every 7,500 miles. I have records of the maintenance for every oil change done on this vehicle. I kept a log and now at 54,740 miles it is consuming 1 quart every 500 miles or so. I took it to the dealer on 10/19/2026 and was told that since I was not the original owner there was no warranty coverage on it. So that nullified the 10 year/100,000 mile warranty. I was told they could do a chamber cleaning for $800.00 and if that failed I would need to replace the engine at an out of pocket cost to me of $9,000.00 to $10,000.00 I have to monitor the oil level constantly to avoid the engine seizing and breaking down in traffic . This auto is used by my spouse to drive my grand kids to and from school. There are no warnings or messages on the oil level so it is driven with uncertainty .

What owners say
My 2020 Kia Sorento stalled and shut off while driving and eventually stopped working completely, requiring it to be towed to a Kia dealership. The dealership first replaced the starter and then the high-pressure fuel pump, but the vehicle still would not operate. After further diagnosis, I was informed that the timing chain had failed/broken and the engine needed to be replaced, with a new engine quoted at approximately $12,000. I am concerned that this type of sudden engine failure and shutdown could create a serious safety hazard, especially if it occurs while driving in traffic or at highway speeds. I am requesting that the federal safety agency document and review this incident for similar failures involving 2020 Kia Sorento vehicles.
Office of Defects Investigation the federal safety agency 1200 New Jersey Avenue SE Washington, DC 20590 Subject: Safety Complaint – Premature Engine Failure Risk Due to Excessive Oil Consumption and Confirmed Cylinder Scoring – 2020 Kia Sorento Dear Sir or Madam, I am submitting a formal safety complaint regarding a 2020 Kia Sorento that is experiencing severe and abnormal engine oil consumption along with confirmed cylinder wall scoring. These conditions indicate progressive internal engine damage and present a significant risk of premature engine failure. The vehicle has been regularly maintained in accordance with manufacturer service recommendations. Despite proper maintenance, the engine began consuming excessive amounts of oil between normal service intervals. During inspection by the servicing dealership, visible cylinder wall scoring was identified within the engine. Cylinder scoring is a clear indication of internal engine wear and deterioration and can lead to rapid progression toward engine failure. Despite the confirmed presence of internal engine damage, the manufacturer has refused to authorize an engine replacement under the extended warranty program unless the engine experiences complete mechanical failure. The dealership has indicated that the vehicle must continue to be operated and monitored until catastrophic breakdown occurs before replacement will be approved. Requiring the continued operation of a vehicle with confirmed cylinder wall damage and abnormal oil consumption raises serious safety concerns. Progressive internal engine damage can lead to sudden engine seizure, stalling, or loss of power while driving, which creates a potential hazard for the driver, passengers, and surrounding traffic. Given the confirmed cylinder scoring and ongoing excessive oil consumption, I respectfully request that the federal safety agency investigate.
Oil is leaking from my car. The dealership said I would need to replace the engine. The car is only 6 years old.
The engine is burning oil despite all maintenance being up to date and having fewer than 80k miles. Kia of Duluth Service Center checked the oil and said levels were good on 12/31/25. Fewer than 30 miles were driven and it was brought back to the dealership service center on 1/2/26 and diagnosed with total engine loss due to oil starvation. The extended warranty company (JM&A) are denying coverage because the engine failure is due to lack of oil. They have inspected the vehicle. No warning lights ever came on and this is the second time that this issue has been addressed by Kia of Duluth. The engine could have easily overheated and caught on fire or lost power on the road.
Around 100,000 miles I noticed that my engine was going through a lot of oil. Every time I would get an oil change, I would ask why and they stated that these Kia engines after hitting 100,000 start to burn oil fast and about every 1,000 miles you have to add a quart of oil and go from your normal every 5,000 mile oil change to every 3,000 mile oil change. Some times the oil light would blink but some times it wouldn't. I had a mechanic double check this and he confirmed and said nothing you can do they are just like and he sees it all the time. I kept up with my oil changes every 3,000 miles and every week and a half checking the oil. Around 134,000 miles or so on 11/28/25 at 4:30am I was driving and all of a sudden my car was driving weird and shaking. Soon the engine light came on. The oil light this entire time never came on. I pulled into a Target parking lot an noticed there was no oil in the car and it went through 5qts in a week and a half. I added 4 qts oil to the car and waited for the mechanic shop 1/2 a mile to open up at 7am. The inspected the car and said a cylinder was blown and to drive slow and get it home and just park it and a new engine is needed. I called my mechanic and he came by the house and he looked and it to see if he could fix it and no luck but said that Kia did have recalls on their engines and to fight it. I called Kia and they didn't deny recalls on some cars but not mine. They advised me to do a claim to get help to get the engine on a recall. The car has not been driven since then and remains in the garage and is in perfect well kept condition otherwise.
Car is in shop 3rd time 2020 sorento with 2.4l thete ii gdi engine. In May e went in p1326 code of death, knocking and blinking light. They put a band aid on. Back in September more issues, oil gasket valve cover and 4 spark plugs. Another bandaid, westarted seeing oil, I thought we were nuts because it was just fixed. Check engine light cane on, read 4th spark plug shot that they put in on 9/25. Tatvfirst rried sating 300 for plug and done. Then day after head mechanic says we need a new engine but all receipts not available. They're not filing a claim for an engine, these engine are blowing up and failing everywhere they just haven't gotten to year 2020 yet in law suits or settlements. When p1326 originally happened we were on the highway and it just decellateared and loud knock! Luckily we were okay and got over fast. With each issue car was immediately brought back to the Kia dealer, the sane dealer I bought the car new off lot in 2020.

Vehicle Information: Make: Kia Model: Sorento Year: 2020 VIN: [XXX] Mileage: ~80,000 miles Complaint Summary: I am filing a complaint regarding excessive engine oil consumption in my 2020 Kia Sorento. The vehicle burns oil between regular oil changes, requiring frequent top-ups. There are no visible leaks, and this consumption poses a serious safety risk, including potential engine failure or fire hazard. Detailed Description: I purchased the vehicle used from a Kia dealership. I requested an oil consumption test from the dealership, but they refused, stating the vehicle is out of warranty. I contacted Kia Consumer Affairs, and they also refused to authorize the test or provide assistance. This engine issue is widely reported by other owners of the 2020 Sorento and similar Kia vehicles, particularly those with Theta II / GDI engines, which are known for oil consumption problems. The vehicle has approximately 80,000 miles, and the oil consumption is significant enough that I must frequently add oil between changes, creating a safety concern. Actions Taken: Requested an oil consumption test from local Kia dealership — refused. Contacted Kia Consumer Affairs for assistance — refused. Maintained detailed records of oil use and maintenance. Request: I request that the federal safety agency investigate this oil consumption issue for my vehicle and the 2020 Kia Sorento model line. I also seek guidance on any recalls, service campaigns, or safety actions related to this defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
My engine has started to burn excessive amounts of oil causing the oil light to flash. I took the car to the dealership and was told that it is a known defect in the engine and that if the car has over 100,000 miles they would recommend getting rid of the car because it could not be fixed and did not qualify for a new engine like they were putting in older models. The dealership said that they had told 9 other families the same thing as me in the last 2 weeks. Apparently the oil flows back into the combustion chamber and ruins the engine and there is no way for the dealership to know until a warning light comes on. Hard to believe since they know there is a major defect in the engine.
My 2020 Sorento has ALWAYS had regular maintenance , very well taken care of. Started using oil around 80,000 miles, around 98,500 it misfired while driving to work and we were told it was the coil pack and spark plugs needing changed. Ran good for 3 1/2 weeks and we had to change another spark plug. Was told this was “ normal” 1 month later and I’m stuck on the side of the road broken down with no power cause the engine quit. By that time we were over 100,000 so Kia said they wouldn’t cover it. Paid to have a new engine put in. Seems like this is a going thing for this make and model. It needs a recall ASAP. It put us in a terrible financial crisis as it was our only vehicle.
Kia Sorento has a well documented engine failure. The issue starts with the vehicle consuming engine oil. Subsequently the connecting rod bearings fail resulting in severe engine failure. This happens even with regular oil change maintenance. I experienced that with this vehicle. Kia was contacted but said this vehicle's vin did not fall under the list of affected vehicles in their class action lawsuit
