Burning oil at dangerous rates. No leak yet having to refill oil weekly. Burning at a rate of 2q per 1k miles. Car currently has 95k miles and has had regular oil maintenance until this issue began a few months ago. This is a frequent issue with the 2020 Sorrento.
The engine is consuming oil at a rapid rate that could be potentially dangerous. This is happening to other people with the same make and model as well.
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 NHTSA 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
Oil consumption issues started around 60k miles took to dealer for consumption test failed it, they decarbonized my piston rings. I returned around 85k miles with the same complaint for oil consumption the dealer did the test I returned they said I passed. I am constantly having to put oil in my vehicle about 2 quarts every full take about (379 miles) the piston rings are causing my spark plugs to be oil fouled Kia knew this and pushed me out the door. Now my car is constantly misfiring and the engine is slowly dying with only 117k miles on it and 5 years old.
The engine oil level drops from "Full" to "Low" after driving approximately 2,000 miles. I have visited three different auto repair shops, including an official Kia service center, but none of them could explain the reason for the oil loss. They all acknowledged the issue but said they don't know what is causing it.
I wasn't in a car accident or anything but my engine is burning oil more then it should like I have to add oil (1 1/2 quarts of oil) every week to my engine and most times when i am driving my car I smell burning oil like its burning inside of the car somewhere and I think that my car is about to caught on fire or just go out. I went up to the kia store to let them know what has been going on and they are telling me that there is nothing that they can do about it, I haven't had this car for a year yet I got this car last year in September they told me that there was nothing wrong with my car, I have 128,000 miles on my car and I just don't know what to do at this point I owe 13,900 on the car. I see that there has been recalls on the kia Sorento's engine before and I even told the dealership about it too and they still told me that there is nothing that they can do, this all start January of this year and I have been fighting with kia over this since then. My car is just a ticking bomb before my engine jsut gives out and I don't know when that will be but I just want to get this fixed and i dont have 5,000 to replace the engine and Kia also told me that they can't replace it either so I'm hoping that this might help me in some kind of way.

I have 105k miles on the vehicle. My vehicle is burning oil between oil changes, so much so that there is no oil on the dip stick. There is a recall for kia engine's doing this but mine is not listed.

According to the dealership diagnostic assessment, the engine has two holes in the block as a result of connecting rod bearing failure. My Kia Sorento engine is a V6. This is a known issue in the Kia Sorento 2.4L for which a recall/extended warranty was granted. The Kia tech service line is denying any assistance with repair/replacement of my engine exhibiting the same engine failure results as the 2.4L engine. The day the engine blew, the oil level was full prior to drive, on the interstate it began sputtering and rattling, the engine then made the sound of a pop or muffled explosion and the car ceased to run causing us to have to quickly divert across lanes of traffic to get safely to the shoulder. Once stopped, the car was noted to have a pool of oil underneath and would ceased to drive.
