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.

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.

I was driving and the vehicle shut off. All electric still on lights, radio, dash, etc. No issues or noises indicating that the engine was having faliure. Did not overheat, had oil and gas. Just bought car used 6 months ago with 140k miles. Had it towed to Mechanic and was told the engine was locked. Engine repair is my only option that is going to cost 5-8k. Vehicle has been maintained regularly with only one previous owner and no major repairs ever needed to be done.

I am writing to express my concern regarding a serious issue with my 2018 Kia Sorento equipped with the 2.4-liter engine. The vehicle has been experiencing excessive oil consumption-?"approximately one quart every 400 miles-?"which I believe may be indicative of a manufacturing defect. Based on similar issues reported with more recent Kia models, including those involving potentially defective piston oil rings, I am concerned that my vehicle may be affected by a similar issue. As you are aware, defective piston rings can lead to long-term engine damage, sudden loss of power, and even an increased risk of engine fire. Given the severity of the symptoms and potential safety implications, I respectfully request that this matter be formally investigated and that Kia consider extending the recall or offering a resolution for affected 2018 Sorento models. I look forward to your prompt response regarding this issue.

Engine oil is always law. Engine eats lots of oil.

GDI engine carbon buildup causing very high gas consumption and damage. Should carbon buildup break free it will cause engine falure resulting in engine seizure while at speed. Loss if property and life imment. Only soulition is disassembly to remove buildup. Another failure is corrosion on shift cable causing gear falure.

- Santa Ana, CA, USA

I bought a used Kia sorento from a Kia Dealership. This engine makes oil evaporate completely. This engine must be a bad engine. I heard there was some recalls on Kia engines not sure if this one fits it. The dealership did a five hundred dollar job on it and it did not fix. I put oil in this car every month. No way to upgrade because of these issues.

I had an engine failure in my Kia. On [XXX], I was driving on [XXX] in Maine, and the "malfunction" light lit up, and I lost power in the vehicle. I was able to make it to the side of the highway and call a tow truck. Losing power on a busy interstate put myself and my partner at risk, as well as having to wait on the side of the interstate for a tow truck. I had the vehicle towed to a mechanic who said the engine needed to be replaced because a cylinder lost compression. Kia had me tow it to a Kia dealership, and they verified that the engine needed to be replaced. The matter is still open. My case with Kia is [XXX]. Kia has been completely unresponsive in the matter. They have told me repeatedly that the matter is being looked into by their tech team, but they have never reached out to the Kia dealership they told me to send it to. It could be related to a rod bearing issue, but they are not willing to follow up enough to even determine whether or not that is the issue. Prior to the engine failure, I had issues with oil loss. I replaced the PCV valve, but that did not turn out to be the problem. I had it inspected a few weeks before the engine failure, and they noted that the oil levels were low. I was not seeing warning lights for low oil, but I was maintaining oil levels while I waited for an appointment to look into that issue. I believe Kia knows this is an ongoing issue with their vehicles, and they are actively obstructing any inquiries as to why this engine problem persists.

Around 90,000 miles, the engine started leaking oil regularly, took it in for warranty. After repairs for gasket, then started burning oil and running of oil every week or two weeks, and I have to constantly refill oil. Took it again and Dealer told me I am out of warranty, then I called KIA USA and reported problems. They told me that they will get back to me and I am still waiting.
