| Nov 2025 | 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. | Crash: No Fire: No | Unknown |
| Nov 2025 | ENGINE AND ENGINE COOLING | The contact owns a 2018 Kia Sorento. The contact stated that while driving at various speeds, the engine was making an abnormal knocking sound. The contact stated that while slowing for a traffic sign or stop lights, the vehicle was shaking and vibrating abnormally. The contact stated that while depressing the accelerator pedal, the vehicle started making the knocking sound again. The check engine warning light illuminated and was now constantly illuminated. The contact stated that prior to the sounds and check engine warning light being illuminated, the contact was constantly adding engine oil, even after an oil change. The contact had taken the vehicle to a dealer, who diagnosed the vehicle and informed the contact that the engine was failing and needed to be replaced. The vehicle was not repaired. The contact stated that the engine was replaced in 2019 by the same dealer. The dealer requested that the engine be replaced; however, the manufacturer later informed the contact that the request was denied. The manufacturer was contacted, and the contact requested an escalation to review the engine replacement and was informed that the escalation had been denied. The failure mileage was approximately 178,000. | Crash: No Fire: No | Unknown |
| Oct 2025 | ENGINE | 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. | Crash: No Fire: No | Unknown |
| Sep 2025 | ELECTRICAL SYSTEM,EXTERIOR LIGHTING,VISIBILITY/WIPER | Lighting and/ or electrical. When using the auto headlight switch, all lights will come on randomly and periodically and stay on until you notice them or they ware down your battery. This is something that could be checked out by dealer and I will ask about it. So, for now, I do not use the auto headlight switch. My other problem is a glass issue. For no apparent reason, when I shut my driver side door a few weeks ago. My entire rear window shattered into pieces. There were no signs of damage to the rear window. Happened in my drive way. But, it could have happened anywhere. Filed a insurance claim and had the rear window replaced. | Crash: No Fire: No | Unknown |
| Sep 2025 | ENGINE | 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. | Crash: No Fire: No | Unknown |
| Aug 2025 | UNKNOWN OR OTHER,ENGINE,FUEL/PROPULSION SYSTEM | 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. | Crash: No Fire: No | Unknown |
| Aug 2025 | EXTERIOR LIGHTING | The contact owns a 2018 Kia Sorento. The contact stated that while driving at an undisclosed speed, the headlights failed to function as intended. The contact, who was a retired certified mechanic, inspected the headlights and determined that the passenger's side headlight bulbs were blown. The contact then noticed a burning odor in the circuit board inside the headlight. The contact stated that the front passenger's side headlight bulbs were replaced twice within three months due to failure. In addition, the contact stated that an unknown manufacturer's recall was performed approximately two years prior, and the multi-function switch knob was replaced. The contact stated that the headlights were not replaced at the time. The manufacturer was not made aware of the failure. The failure mileage was unknown. | Crash: No Fire: No | Unknown |
| Aug 2025 | UNKNOWN OR OTHER,ENGINE | 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. | Crash: No Fire: No | Unknown |
| Aug 2025 | ELECTRICAL SYSTEM,ENGINE | 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. | Crash: No Fire: No | Unknown |

| Aug 2025 | EXTERIOR LIGHTING | My lights are set to auto but when driving they randomly switch off. The dash shows the switch from auto to off but the control is still set to auto. I have to manually switch the control off and then back on for the lights to come back on. I’ve also noticed a few times in the morning my lights are on. My switch is set to auto and my car is completely off but the lights are on. This is very unsafe as it happens at night and I can’t see the road. | Crash: No Fire: No | Unknown |
| Aug 2025 | FUEL/PROPULSION SYSTEM | * High pressure fuel pump quick disconnect fuel line fitting leaking fuel. * Raw fuel leaking poses a risk of fire and danger to the vehicle occupants. Raw fuel leaking in a closed in area as it did in my garage could have lead to an explosion due ignition of the fuel vapors. * My vehicle was repaired by a KIA dealership. The dealership noted that they've seen this issue several times in the past few months including one instance where the fuel line fitting actually fell off. The dealership acknowledged this failure hasn't yet become a recall issue which is why I'm filing a complaint with the NHSTA to establish a record of the issue. * The component was probably discarded by the dealership. The dealership didn't mention sending the part out for inspection or reporting the issue to the manufacturer. Galeana KIA did provide 2 pictures of the fuel leak area. I've attached these to this form. * There were no warning lamps or messages for this type of leak. The vehicle drove as normal. It wasn't until I parked the vehicle in my garage that I noticed a strong smell of raw fuel. | Crash: No Fire: No | Unknown |
| Aug 2025 | ENGINE | 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. | Crash: No Fire: No | Unknown |
| Aug 2025 | EXTERIOR LIGHTING | The headlights will randomly turn off while driving, mostly when turning on the right blinker.

| Jun 2025 | STEERING | The steering started to fail and would be hard to steer while driving.I then looked further online and found that a recall was issued for the steering column and how dangerous it was to continue driving the vehicle for the cross as stated in the recall could seperate and one could lose steering and cause a crash so we; my wife and I managed to get the car safely to the dealer for further diagnostic only to find out that although a recall was issued for the steering problem. Our vin was not included and we had to pay for the repair. | Crash: No Fire: No | Unknown |
| Jun 2025 | STEERING | Sometimes this condition hardly noticable and other times very stiff then move steering wheel slightly and full assist. Seems more prevalent after driving 1/2 hour or more on expressway steering becomes stiff and ratchety. This causes steering to stick whenever driving at highway then driver is putting more effort to overcome stuck wheel. When breaks loose vehicle goes to far in that direction then sticks again causing to stick again and over corrects other direction. This goes from annoying and uncomfortable to just plain dangerous depending on conditions speed weather and proximity to other vehicles or obstacles. | Crash: No Fire: No | Unknown |
