2018 KIA SORENTO Engine Problems

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...

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.

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.

Excessive oil consumption

The engine suddenly failed while I was driving on the highway. The vehicle lost power without warning, which created a dangerous situation. I had to pull over and have the vehicle towed.

Engine is burning oil at a rate of almost one quart per week. The engine can be felt shaking when driving. The engine light came on and states there is a P0303 Cylinder 3 misfired detected.

Started the car and heard a knocking sound. No check engine or low oil light on the dash. Dealership said the bearing clearance test was too great, causing the connecting rod to knock inside the engine. Dealership said I need an engine replacement. Engine is 3.3L Lambda II engine which has been reported to have this issue.

I was driving from richlands coming home and my vechial kept trying to die on me like i didnt have any gas and then i had to suddenly pull off the side of the road without any power and i sat their and even try to restart the vechial and it wouldn't start back then a woman come out of nowhere in an ambulance and i was trying to tell her that it was alright and she was trying to tell me that the vechial was on fire underneath the vechial and i didnt see that it was a fire at all i though i was overheating so i was sitting in the vechial waiting on it to cool down thank god i was not hurt really bad if this would have happened somewere else i know i would be dead i already have smoke in my lungs from breathing...

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...

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.

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....

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.

The contact owns a 2018 Kia Sorento. The contact stated that upon starting the vehicle, the vehicle made an abnormal knocking sound. Additionally, the contact stated that while driving and depressing the accelerator pedal all the way to the floorboard, the vehicle failed to exceed 18 MPH. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed, and the failure was linked to the knock sensor detection system(KSDS). The vehicle was not repaired. The local dealer was unreachable. The manufacturer was not notified of the failure. The failure mileage was 85,798.

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.

Excessive oil consumption, 4 quarts in 2000 miles

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.

Engine burns and eats up lots of engine oil. Engine oil is always low.

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...

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.

While driving on the highway, the engine suddenly stopped working without warning. I was unable to accelerate using the gas pedal. Fortunately, the highway was empty at the time, and I managed to safely pull over to the right side of the road. After waiting for approximately 30 minutes for the engine to cool down, I attempted to drive again. However, the car began shaking severely whenever I pressed the gas pedal or attempted to increase the speed beyond 2 RPM. The vehicle was subsequently inspected by a certified Kia service center, where the issue was diagnosed as a failure of the piston ring and cylinder 1, resulting in insufficient compression. The service center confirmed that the vehicle was well-maintained, with no external damage or user-related issues contributing to the failure. No warning lamps, messages, or other symptoms appeared prior to the failure. The engine issue was sudden and unexpected,...

Previous Complaint# 11618337. Additional Information: Engine is full of oil yet Oil Light comes on due excessive crankshaft & connecting rod bearing wear and knocking loud. Yet the recalibrated knock sensor will not pick up the issue and put the vehicle into derate with a code P1326 as it did before the Kia Dealership performed this recalibration. This is consumer fraud by purposely hiding a known defect and preventing the warranty from replacing the engine with a redesigned new engine that corrects the issue with larger oil ports. It is also a safety issue!! Now that the oil light is coming on and the engine has a bad knock, it can fail at anytime while driving causing lose of power steering, brakes and the ability to safely pull the car over to a safe location. The original P1326 code automatically determined the engine developed wear from lack of oil volume...

My kia Sorento is involved in an engine recall. When driving on the highway three times now my engine has stalled and car has gone from 65 to 30 mph, almost causing multiple accidents while driving with my [XXX] and [XXX] . The Kia customer service agency said this must occur three times before they will replace my engine. They are not replacing the engine. I fear for my life, my husband life and my children’s lives . I also fear for fellow drivers on the road . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving my 2018 Kia Sorento up a hill going about 40 mph. It suddenly lost power and I had to pull over. No lights showed up on the dash warning me anything was wrong. I was draining oil like crazy and it was all over the engine. I had it towed to a mechanic and then the dealership. A bolt from inside the engine blew and tore a hold in the valve and head gasket. That’s all I know now. I had purchased my vehicle pre owned certified, and Kia is not honoring the warranty even with extended warranties. This happened at 87,000 miles. I have seen other reports of Kia Sorentos having issues with their engines. Please help.

Engine was consuming large amounts of oil, attempted to conduct oil consumtion test per Kia request was unable to complete due to volume of oil consumption . Engine locked up after kia telling me they couldnt help me since the oil consumtion test couldnt be completed.

My 2018 Kia Sorento sticks and when pushing the gas and the RPM jumps up. The car also stalls out and then turns right back on. It shakes and makes a funny noise as well.

I have a 2018 Kia Sorento that I absolutely love. As of late, I have noticed that 1,000 to 1,200 miles after my oil changes- I am getting my engine oil light on, on the dash. Upon checking, again after only 1,200 miles after an oil change- my engine oil was completely gone. The dipstick was almost bone dry. I took my vehicle in to have an oil leak test, because I instantly thought I had a leak due to that being an excessive amount of oil missing. However, there is no leak. It passed the leak test, and there is also no oil in my driveway. Upon talking to the Kia dealership this is apparently a very known, and prominent issue with this vehicle. I am "out of warranty" with Kia- so I am unable to file a claim with them to have this repaired. This is unacceptable for...

Engine had catastrophic failure without warning. No warning lights or performance issues. 110K miles on it. Well taken care of and taken in for oil changes at regular intervals 6K-8K.

Oil leak was diagnosed as bad oil pressure switch that is under extended warranty for certain Kia Sorento models with GDI system, but not my car.

The engine seized as we were driving onto the freeway. Everything just stopped. The car had to be pushed to the side of the road. It failed to restart. When we checked the dipstick, it was completely dry and starting to burn on the bottom. There was no visible signs of an oil leak. There were no lights or other notifications that the car was out of oil. We were lucky the car wasn't hit and someone seriously injured or killed. The car had to be towed to our home. Kia Corporate Office was closed. The Kia dealership said I could have it towed at my expense and have it looked at when they had time the following week. It was just under 100K miles A different Kia dealership offered to give me $5000 towards a trade-in on a new car. That was half the trade-in value, but I couldn't...

Engine is burning oil. Engine only has 116,000 miles on all maintenance has been kept up to date - has never missed an oil change, only ever used full-synthetic. Should not be consuming this amount of oil. Also dash board lights pertaining to engine or oil never come on.

Car is burning 3/4 a quart of every 1,000 miles

On May 1, 2024, I noticed my 2018 Kia Sorento making a knocking sound and smoking heavily from the back exhaust. I turned it off, thinking it might be overheating, and planned to check it the next day. On May 2, 2024, while taking my daughter to school, the vehicle was knocking but no indicator lights were displayed, the main display screen suddenly showed an engine control system issue, and the car spoke and said to take the vehicle to the closest service center I immediately headed to the Kia service center. About 2-3 miles into the drive, the car shut down completely on the interstate. I managed to coast to a stop on the access road but was still partially on the road, so I called for a tow. The police later helped me move the car further off the road because I was a hazard for Morning rush...

My vehicle is consuming a lot of oil. At my previous oil change I mentioned this to the dealer as I had to put in 5 quarts of oil. The oil canister light came on which I believed was just warning me to my upcoming oil change but my dipstick indicated otherwise when I checked. The light would only come on when I made turns in the road. It did not stay on consistently. As I was driving my engine sounded bad and I was worried something more was wrong which is why I checked the oil. When I brought it in for the oil change, the service advisor said they would check for leaks which was not located. I asked them to set my oil change for 3k miles instead of the 5k miles they have been setting it as I was worried about engine damage. The oil canister...

The contact owns a 2018 Kia Sorento. The contact stated that while driving at 55 MPH, the vehicle lost all power while depressing the accelerator pedal without warning. The contact also stated that white smoke began to emit from underneath the hood of the vehicle. Upon inspection of the vehicle, the contact saw flames coming from underneath the vehicle as oil began to leak from the vehicle. The flames eventually dissipated and authorities were not called to the scene. Due to the failure, the vehicle was towed initially to the contact's home and later to the dealer. Once in the dealer's possession, the contact was informed that there was a hole in the engine block which had led to engine failure. The manufacturer was notified of the failure but had yet to offer any assistance. The vehicle remained in the possession of the dealer and had yet to be repaired....

Vehicle seems to be stalling when you stop and then try to pull out. It takes minutes to accelerate after stopping.

The vehicle started knocking. We took it to Kia and they share saying we needed an upgrade part that is on a safety”notice” and not a recall. It’s to prevent engine failure. They refuse to put in the part because they said the engine is already failing. They said we need to pay 6k. The best part is that we took the vehicle in last year (2023) for the hitch and the anti theft upgrade and KIA didn’t tell us about this feel part. Why wouldn’t we get the free upgrade on the engine???? They are not telling consumers and it doesn’t come up when you search by VIN.

Me and my wife were traveling north on [XXX], left lane, 18 wheeler in right lane, cars directly behind us, 70 mph, when there was an abrupt thud, and slight skid, then lost all power from the engine. There were no warning indicators at the time. When the engine failed, we almost hit the tractor next to us. Looking in the mirror to try to determine what to do, as steering was hard to perform, there was a large cloud of black and blue smoke, the car behind us being covered in smoke and most likely oil too. The car behind us aggressively braked and ducked in behind the 18 wheeler just before a rear impact would have occurred. We finally got to safety on the side of the road as the traffic stacked up behind us was able to reduce speed in time. I had my car towed to...
