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)

While on the road driving at 35 MPH, the vehicle started to "bog" and losing power and/or acceleration. Had to immediately drive off the road as there were several vehicles behind. As soon as driving off the road, the vehicle died down and would not start again. The check engine light came on. After several minutes the vehicle started again and drove to a secure area to call the tow truck. If the vehicle died down while in traffic, it would have caused an accident involving several vehicles. If it happened on the freeway, it would have caused a "major accident". The vehicle was towed to the vehicle dealership. It was determined by the vehicle dealership that the "high pressure fuel pump" was faulty and had to be replaced. It took four (4) months for the replacement part to arrive. Another similar dealer said that there were "55 other vehicle owners" waiting on the same part nationwide. It must be an "inherent problem" with the high pressure fuel pump. After replacing the high pressure fuel pump, the vehicle was operating normally.

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.

The contact owns a 2018 Kia Sorento. The contact stated that upon starting the vehicle, there was heavy white smoke coming from the exhaust pipes. There was no warning light illuminated. Upon taking the vehicle to an independent mechanic for an oil change, the contact was informed that there was an oil leak coming from the engine. The contact had her son inspect the vehicle, and he discovered that oil was leaking onto the spark plugs in cylinder #1. The contact’s son diagnosed the vehicle with engine failure and recommended that the engine be replaced. The contact then stated that while driving 60 MPH, the vehicle started shaking with the check engine warning light illuminated. The contact pulled over and waited for approximately an hour before being able to restart the vehicle and drive to the destination. The vehicle was then taken to a dealer, where a diagnostic test was performed, and the dealer discovered several oil leaks in various cylinders. The vehicle remained with the dealer. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was unknown.

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 the federal safety agency 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.

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.
