Your 2020 Kia Sorento is consuming excessive oil between service intervals and has visible scoring (damage) on the cylinder walls inside the engine. This internal damage indicates the engine is deteriorating and could lead to sudden engine seizure, stalling, or loss of power while driving, creating a safety hazard. Kia has refused to replace the engine under warranty until it completely fails, requiring you to continue driving a vehicle with confirmed internal damage. Addressing this will likely require a full engine replacement or major internal engine repair.

Your engine is burning through oil rapidly even though you've kept up with all scheduled maintenance and have fewer than 80,000 miles on your car. The dealership confirmed oil levels were fine on December 31st, but just 30 miles later your engine failed completely due to oil starvation, even though no warning lights appeared. Your extended warranty is refusing to cover the repair, claiming lack of oil caused the failure. This is a recurring issue at your dealership, and your engine could have overheated dangerously or left you stranded on the road.

Your engine check light is on with a cylinder 4 misfire code (P0304). You're experiencing reduced power, slow acceleration, and difficulty starting even after replacing the battery and spark plugs. Your engine is also burning oil, and multiple mechanics have indicated the engine may need replacement. The vehicle has become unreliable as your primary transportation.

Your engine check light is on, and your car is consuming oil much faster than normal—you've had to add several quarts of oil before reaching 2,000 miles after an oil change. An inspection found that cylinder 2 is misfiring and has low pressure, which means your engine will likely need to be replaced. Kia has indicated your vehicle is not covered under a recall for this issue.

Starting around 100,000 miles, your engine began burning through oil rapidly — requiring an oil top-up every 1,000 miles and shortening oil change intervals from 5,000 to 3,000 miles. At 134,000 miles, your engine started shaking and the check engine light came on after losing 5 quarts of oil in just a week and a half, despite the oil warning light never illuminating. A mechanic determined a cylinder had blown and that your engine needs complete replacement, though Kia did not honor a recall claim for your specific vehicle. The repair will likely involve engine replacement or a complete engine overhaul.

Your 2020 Kia Sorento's engine began showing problems after 100,000 miles, but you were told you're not eligible for the ongoing class action lawsuit settlement even though the settlement documentation lists 2020 Sorento models as covered. You believe there's a timing issue with claim deadlines that's preventing you from filing, despite owning the car since new in 2020. Engine repairs or replacement may be needed to address the underlying problem.

Your check engine light came on indicating a misfire in cylinder 4. Even after replacing all spark plugs and the coil pack, your car still has trouble accelerating, especially at higher speeds, even though the light went out. The underlying issue may involve fuel delivery, compression, or valve timing that wasn't addressed by the spark plug and coil pack replacement.

Your engine is leaking oil and burning oil, which means oil is escaping from the engine and being consumed during operation. You may notice oil spots under your car, low oil levels on the dipstick, or blue smoke from the exhaust. The repair will likely involve identifying the source of the leak (such as gaskets or seals) and replacing the damaged parts.

Your engine's oil pan developed a large crack near the drain plug. This could cause oil to leak out, potentially leading to low oil levels and engine damage if not repaired promptly. The oil pan will likely need to be replaced or professionally sealed.

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.

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.

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.

My sorento was making a propellor type sound when driving up an incline. There were no lights on my dashboard. I took it to a Kia dealership as it is under warranty.

The safety of myself as well as my husband and 4 kids was put at risk b y the fact that it was during the solar eclipse, and our area highways were bumper to bumper traffic. With multiple accidents already happenening in the area. Had we not safely been able to exit the highway ourselves as well as any other individual around us could have been in imminent danger of a serious accident. The problem has absolutely been confirmed by Larry stovesand kia as well as sales automotive. The vehicle has not further been inspected.

Car died and was smoking. Checked oil level and it was at L on dipstick. Kia is saying it is the fuel injectors and are still not taking care of the oil consumption. Was told fuel injectors are not covered under warranty and that I have to do another oil consumption test after injectors are fixed.

My vehicle developed an unexpected oil leak, when the oil plug worked itself loose, and then fell out, resulting in a catastrophic engine failure (and subsequent $11,000 engine replacement). Upon taking it to a nearby mechanic, he discovered the plug sitting in the splash shield. The sudden loss of engine power, on the highway, created a traffic hazard for myself, and the other motorists around me; fortunately, I was able to maintain control of the vehicle, and move it to a safe location. The problem has been documented several times to the NHTSA, as well as several other organizations related to vehicle maintenance, specifically oil changes and services. There were no indications as to an oil leak, prior to the plug falling out entirely, and a cloud of black smoke billowing out from behind my vehicle.
