My car for the last 2 years has had multiple malfunctions with misfiring and replacement of head gaskets, pistons and more. Not to mention consistence oil concerns. On two occasions my family and I had to have the vehicle towed home over 200 miles because the car was not driving well. I have a [XXX] ghter who was with us at the time. The only warning lamp that ever triggered was the check engine. In October is when I was informed about a recall that was on my vehicle from KIA the corporation and I was told to have it towed to Kia in [XX [XXX] ey would replace my engine if the rod barring failed; and it did. Kia refused to pay for the engine and reported that I was misinformed. In December of 2025 I went through the Attorney General for mitigation to try and fix the engine- However, Kia reported because the engine manufacturer recall was not updated prior to October 30th or 2020 it was considered failure on the consumers part for not updating their address. However, I have documentation that the vehicle was sign for by myself on December 2nd of 2020. I have the car fax reporting that the car was surrendered by the previous owner on October 28th, 2020. Therefore, I was not the own when this manufacturer warrantee recall was in place or when it expired. So, I do not feel since i did not own the car when this was to be completed, that I should be responsible. Not to mention I am paying on the loan that financed this vehicle for the last 7 months while it has sat at KIA in [XXX] [XXX] ION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

In April, 2025, my vehicle's engine power was significantly reduced while on the highway. I could not keep pace with traffic. My mechanic said there were recalls for the turbo engine but my car was not included. I paid forbthe part and repair. Less than a year later and the car began burning a lot of oil very fast. I add oil weekly. The car has again been losing power and there is still no recall for my car's engine. There is burning and smoke coming from the engine because of an engine oil leak Jiffy Lube detected yesterday, Mar h 11, 2026. The problem began at around 65k miles and now has 88k miles.

The contact owns a 2018 Kia Sorento. The contact stated that while driving at an undisclosed speed, the vehicle started shaking and making a rough sound. The vehicle hesitated while accelerating and lost motive power. A piston failed, causing oil to spray out with enough force to damage the catalytic converter. The vehicle was driven to the dealer for an unknown recall repair, but found to have issues with the engine. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 127,000.

I have less than 100,000 miles on my 2018 Kia sorento. When I reached probably 50,000 miles this car went DOWN HILL. I feel like I-??ve replaced everything on this car. Now every oil change was saying no oil on the dip stick, so I take it to the Kia dealership. They tell me that I need an ENTIRE engine. My car is less than 100,000 miles. I saw something that said if it was under that threshold, it could be covered but they said they couldn-??t find anything. This car has been failing me. I still owe HALF of the car, what it-??s not even worth on carfax anymore. AND the engine cost is exactly 50% of what I owe on this car. I don-??t know what to do, but never buy a Kia again. This is a hazard for everyone around me the gas it is putting into the air. I don-??t know what else to do. I even paid them to do an oil change and the oil light lit up as SOON as I left the parking lot. There are no leaks whatsoever. I even had someone from the Kia engine settlement verify my VIN # and told me that it was eligible and she told me that everything would be taken care of at the dealership without charge. She then told me to wait for the dealership to call and let me know because I was on hold while they were talking. But right after I received a call asking how I was going to pay for it because they could not find anyway to cover it. I don-??t know how to ask for a second opinion. Kia is never available to speak with or try to resolve the issue. This has just been a nightmare.

On January 30, 2026, I was driving with my daughter from Kansas City to Platte City when the vehicle experienced a sudden and catastrophic mechanical failure. As we approached our exit, the engine unexpectedly revved and the vehicle rapidly decelerated to approximately 30 mph. When I attempted to accelerate, the vehicle was unable to properly gain speed. Upon reaching the top of a hill at an intersection, the engine completely shut off and the vehicle became disabled in the roadway. The vehicle was towed and inspected by two independent repair facilities. Both repair facilities confirmed catastrophic internal engine failure. A bore scope inspection identified a broken valve in cylinder 4, along with severe internal engine damage. The first repair facility estimated the cost of engine replacement at $9,600. The second repair facility confirmed the same diagnosis and recommended full replacement of the long block assembly. Copies of the inspection reports and repair estimates are attached. Due to the extent of the internal damage and the high cost of repair, the vehicle is considered mechanically inoperable and beyond reasonable repair. The cost of repair is substantial and exceeds our ability to proceed with repairs. At the time of the mechanical failure, approximately two years remained on the finance agreement, with an outstanding loan balance of approximately $12,000. As a result of this catastrophic mechanical failure, the vehicle is unusable, and a financial deficiency remains on the loan. Although the engine carried a warranty, we were informed that the specific failure was caused by internal component failure and material shedding, which is not covered under the warranty terms. Supporting documentation, including diagnostic findings, repair estimates, and photographs of the failed engine components, are attached. Due to the sudden and catastrophic mechanical failure, the vehicle has sustained a total mechanical loss and is no longer operable.

2018 Kia Sorento 2.4 GDI. In late 2024 a Kia dealer performed an oil-consumption test and confirmed the engine was burning excessive oil. In Feb 2025 the engine long block was replaced. Within about 4,000 miles the vehicle began setting P1326 warnings, misfiring, losing power, and struggling to climb hills. On a highway trip from South Carolina back to Indiana, the vehicle could barely maintain 30-?"40 mph on grades with the accelerator floored while traffic was moving much faster. The check-engine light returned repeatedly. The vehicle eventually died on an exit ramp and had to be pushed out of traffic and towed. I felt it was unsafe to drive but was repeatedly told by dealers that it was -??OK to drive-?? or that the issue was -??bad gas.-?? After visits to multiple dealers, the current Kia service center finally diagnosed a severely clogged exhaust. They report the manifold catalytic converter and underbody converter have broken down internally and are heavily coated in carbon/oil deposits, and state this likely came from the engine burning oil before and around the time of the rebuild. Exhaust temperatures have been recorded at very high levels, and the engine will only run briefly with an O2 sensor removed to vent exhaust; with the exhaust sealed it will not stay running. The dealer has warned there may now be internal engine damage from prolonged backpressure. The vehicle has been undriveable for many months and the failed converters are being retained and are available for inspection. My concern is that excessive oil consumption on these GDI engines is causing secondary catalytic-converter failure, extreme power loss, stalling risk, and possible fire risk from overheated exhaust components, even after engine replacement.

My car had an issue that was covered under a class action lawsuit. I even had an extended Warranty which was still valid at the time. I was intimidated by the warranty company when they said well if there is carbon build up in the engine the cost of the repair is on you. So I didn't have it fixed and the engine blew up and is now inoperable in my driveway. So bottom line I couldn't get KIA to help me or the extended warranty company when clearly it was KIA's responsibility to fix there defect in the engine.

- Cape Coral, FL, USA

Noticed excessive oil consumption that turned into burning oil when the exhaust turned back of car black. Engine started knocking due to gummed up spark plugs. Replaced the spark plugs but within weeks the new plugs where gummed up as well. Took to Kia for diagnosis and potential repair for theta 2 class action. Mechanic confirmed damaged spark plugs, piston issues and needs for new engine.

My Vehicle-??s Problems Excessive Oil Consumption My engine kept losing oil far more rapidly than normal. I was regularly checking and had to top off the oil, even though mileage suggested it should not be that frequent. However, there was no -??check engine-?? warning light or low-oil warning light even when the oil level was dangerously low. Despite the oil being burned or lost, none of the sensors ever alerted me. Eventually, before my next scheduled service, the extreme oil loss culminated in catastrophic failure: the engine seized, and the car is now completely undrivable. Engine Failure / Seizure The engine-??s seizure was sudden and without any prior warning. There was no indication via -??check engine-?? light, oil light, or other dashboard warnings. I have obtained an estimate for replacing the engine, and regrettably, the cost of a new engine exceeds the current value of the vehicle. This is deeply unfair, given that the root cause appears to be excessive oil consumption, not misuse or accident. Lack of Responsiveness / Remediation I feel that despite my efforts to maintain the car and monitor oil levels, I was left to fix a major and very expensive defect. I request that Kia take full responsibility: cover the engine replacement (or provide a buyback / repurchase option), reimburse me for costs, or find another equitable remedy.

Started with check engine light coming on then having problems with engine knocking last winter. During oil change and oil filter change there were gold "sparkles" throughout the old oil and the filter was completely covered. It appears some component of the engine is being "chewed" up and destroying our engine. It is now undrivable. I was told by our local mechanic shop to contact KIA or NHTSA regarding a special extended warranty from KIA specifically for engine issues. I am not finding anything specific online, so wanted to reach out. I am waiting to hear back from local KIA dealership service department as well.

KIA Sorento 2018 The vehicle experienced engine failure due to piston ring damage at approximately 111,500 miles. A Kia dealer diagnosed the issue with codes P0301 and P0304 and confirmed the engine requires full replacement. This creates serious safety concerns, including engine misfires, loss of power, and risk of stalling while driving.

- Kalamazoo, MI, USA

The Vehicle emits a strong fuel odor: seems to be around the rear of vehicle & front engine compartment of vehicle. Seems the fuel system, both low & high pressure fuel pumps and their pipes channels are leaking to emit a strong fuel odor. Extreme high volatile combustion & fire risk! Remedy: the fuel system including both low & high pressure fuel pumps & their pipes channels need replaced with strong, better engineered components! A newer vehicle like this should not be having fuel system failures.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The engine misfired due to a broken valve in one of the cylinders. This failure occurred approximately two months after completing the scheduled 100,000-mile service at a Kia dealership. The affected parts (valve, cylinder components) should still be available for inspection by Kia or a third party. 2. How was your safety or the safety of others put at risk" The vehicle suddenly lost power and stalled in the middle of the highway while driving at normal speed. This created a dangerous situation where I could have been struck by oncoming traffic while trying to safely exit the roadway. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? The issue was confirmed by a repair shop, which diagnosed the cause as a misfire due to a broken valve. I have service documentation of the diagnosis available. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has not yet been inspected by the manufacturer or insurance representatives, but it was inspected by the servicing dealership and/or an independent mechanic who confirmed the valve failure. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear" Prior to the complete failure, the check engine light illuminated and the vehicle began running roughly (misfiring). These symptoms appeared very shortly before the breakdown, giving me no meaningful time to react before the engine stalled.

My vehicle started with oil issues took to dealer and the attempted to perform an oil consumption test however the vehicle would not pass the test as the oil would not last long enough for next test. Was advised I needed an engine, Kia refused to replace since it wouldn-??t pass consumption test. I paid for engine replacement 1month later engine light comes on, again I return to Kia dealer they say engine needs replacement they replace supposedly through warranty. Drive for about 30 days and engine light comes on again takes to dealer and they say it-??s the knock sensors code which is the same code that came up prior to engine replacement. The knock sensor was a recalled part that they replaced by them but now are refusing to replace even though they replaced it less then 12 months ago.
