The engine is consuming a quart of oil per thousand miles.

3 Engine And Engine Cooling problem

Failure Date: 04/13/2026

My 2021 kia Soul experienced repeated overheating despite replacement of major cooling system components including the thermostat and water pump. The vehicle continued to overheat and was later diagnosed by a kia dealership with engine damage requiring full engine replacement. This failure occurred around 105,000 miles. The symptoms and failure pattern are consistent with known issues affecting similar kia engines, yet my VIN is not included in any recall. I am concerned this represents a broader defect that may not be fully captured in current recalls.

The contact owns a 2021 kia Soul. The contact stated that while driving approximately 80 mph, the vehicle unexpectedly stalled, with the check engine warning light illuminated. The vehicle was restarted; however, the failure reoccurred. The contact stated that while driving uphill, the vehicle failed to accelerate as needed. The vehicle was taken to the dealer, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and case was opened. The approximate failure mileage was 41,000. The VIN was not available.

5 Engine And Engine Cooling problem

Failure Date: 04/07/2026

What component or system failed or malfunctioned? the engine (piston rings) and catalytic converter failed. The catalytic converter is available for inspection upon request. How was safety put at risk? the engine ran low on oil without any external leak, causing warning lights and engine rattling. Low oil pressure can lead to sudden engine seizure or fire. The failed catalytic converter can clog, causing loss of power on highways and increasing the risk of a crash. Has the problem been confirmed by a dealer or independent shop? yes. A kia dealer found the engine 2 quarts low, with no external leak, and recommended replacing the catalytic converter at a cost of over $6,000. An independent mechanic confirmed code p0420, which indicates catalytic converter failure. Has the vehicle been inspected by the manufacturer? the vehicle was inspected by an authorized kia dealer, but they did not complete the required inspection for recall sc336 (defective piston oil rings). They did add the software. Were there warning lamps or other symptoms? yes. The oil pressure warning light and other dashboard lights came on. The engine made a rattling noise. The vehicle later felt sluggish on acceleration, fuel economy dropped, and the exhaust developed a smell. The check engine light came on and later turned off, but code p0420 was stored in the system.

Mi carro hay veces que prende la luz DE la engine, lo lleve a checar y salió en la computadora que era un problema DE power train system, que era secondary dtcs p1c28 y p1c28000, lo busque en google y salía que era un problema muy recurrente en kias Souls y sorentos. Que podría causar incendios.

7 Engine And Engine Cooling problem

Failure Date: 04/07/2026

Hi my vehicle was stolen and the police found the vehicle. The car was damaged part of the damages was a broken ignition. I am unable to fix the damages until I get paid from the kia classaction lawsuit. The car still starts and stays running. I have the key for the car but I have been starting the car was butter knife bc it's easier then the key. I made an appointment to have the oil piston ring looked at. When I brought it I. They refused to look at it bc it has a broken ignition. I don't think the safety recall has anything to do w the ignition. The car is easy to turn on and shut off. I wouldn't care if my car wasn't stalling at traffic lights. My car is going thru a lot of oil. I am not working currently. This car was purchased for me by my dad. He paid cash for it. He bought it bc I had just been diagnosed w a rare autoimmune disease. He bought it so I would have something safe and reliable to drive in. We have had nothing g but problems since day 1. All I wanted was for them to look at it so im not going to be in harms way. Idk what to do the dealership said they cant look at it until I fixed the ignition. But like I said I won't have money to do that until I get the class action lawsuit.

8 Engine And Engine Cooling problem

Failure Date: 03/30/2026

On [xxx], the check engine light illuminated. No other warning indicators activated — no low oil pressure warning, no low oil level warning, no driver alert of any kind regarding engine condition. On [xxx], at approximately 53,845 miles, the vehicle began running rough. I checked the engine oil and found the dipstick registered empty — no measurable oil in the engine. No low oil level or low oil pressure warning had been provided by the vehicle at any point prior to this discovery. I added two quarts of oil. The vehicle stalled while being driven to obtain the oil, and stalled again after the oil was added. I drove the vehicle to jiffy lube and had a full oil change performed. Mileage at the oil change was 53,852. I then scheduled an appointment with gervais kia in lowell, massachusetts, the nearest kia dealer, less than one mile from my home. The earliest available appointment was approximately one week later. Because the vehicle stalled repeatedly at idle, I drove it to the dealer using both feet — keeping engine revs elevated with the accelerator while braking — to prevent stalling at stops. The vehicle is currently at gervais kia for diagnostic inspection. The symptoms match the failure mode documented in NHTSA recall campaign 25v-099 (kia recall for 2021-2023 Soul and seltos with 2. 0l nu mpi engines, piston oil ring manufacturing defect). My vehicle has the 2. 0l nu mpi engine and was manufactured at the kia autoland hwaseong plant identified in the recall filing. However, my VIN does not appear in the current recall population per NHTSA VIN lookup and kia’s recall lookup. The recall remedy includes installation of piston-ring noise sensing system (pnss) software specifically because the defect provides no driver warning before failure — consistent with my experience, in which the engine ran empty of oil with no warning whatsoever. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

9 Engine And Engine Cooling problem

Failure Date: 03/30/2026

I am writing to formally report a failure by classic kia of streetsboro to provide the federally mandated safety remedy under recall sc336 for my 2021 kia Soul (VIN: [xxx] ). I have reason to believe the dealership has bypassed the mandatory safety protocols by intentionally omitting my documented diagnostic data—specifically codes p0014/p0017, engine stalling, and excessive oil consumption—from the techline case narrative. Evidence of non-compliance: 1. Improper component installation: despite the documented timing failures, the dealership appears to have installed a short block (part # 21102) instead of the required long block assembly (part # 21101-qqk). This leaves my oil-contaminated camshafts, valves, and vvt solenoids in the vehicle, posing a continued stalling risk. 2. Failure to address consequential damage: the dealership is attempting to charge me a $99 "customer pay" fee for a catalytic converter back-pressure test. Under sc336, testing for consequential damage caused by a defective engine is the manufacturer's responsibility. 3. Withholding documentation: the dealership has refused to provide the techline case number or the engine part number upon request, preventing me from verifying that the safety remedy was performed correctly. I will not be taking possession of the vehicle until kia corporate verifies that a long block assembly was installed and that all diagnostic fees related to the recall symptoms are waived. This matter is currently being escalated but could definitely use your assistance. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

10 Engine And Engine Cooling problem

Failure Date: 03/29/2026

I am filing a complaint regarding a safety recall (NHTSA recall 25v099) on my 2021 kia Soul that was marked as completed, but the defect was not properly repaired. On 3/17/26, I took my vehicle to a kia dealership to have the recall addressed. The dealership performed only a software update and diagnostic testing and marked the recall as complete. No engine repair or replacement was performed. Within approximately one week of this recall service, my engine suffered a catastrophic failure while driving, resulting in a hole in the engine block and total engine failure. This created a serious safety risk due to sudden loss of power and fire hazard. I then had the vehicle inspected by a second kia dealership. They informed me that the engine failure was consistent with the defect described in recall 25v099 (piston oil ring failure) and that the prior recall repair did not correct the underlying issue. This indicates that the recall remedy performed on my vehicle was incomplete or ineffective, and that the vehicle was returned to me in an unsafe condition. I am concerned that other vehicles may be receiving only software updates without proper inspection or repair, which could lead to similar dangerous failures. I am requesting that this situation be investigated as a failed recall remedy and a continued safety risk. Timeline: 3/17/recall repair performed (software update only) 3/29/engine failed catastrophically 4/2/second dealership confirmed failure related to recall defect.

11 Engine And Engine Cooling problem

Failure Date: 03/28/2026

Nhtsa safety complaint: recall sc336 (campaign 21v-301) non-compliance VIN: [xxx] I. Pattern of recall evasion vehicle (2021 kia Soul) was towed to classic kia [xxx] ) on 3/13 with documented engine stalling, knocking, and codes p0014/p0017 (vvt/timing failure). The dealership withheld this data from kia techline for 13 days (3/13–3/26), delaying the safety remedy until state authorities intervened. Ii. Mechanical impossibility & remedy violation on Saturday 3/28, the dealer claimed a full engine swap was "installed and tested" in only 6. 5 hours (7:30 am–2:15 pm). Per the sc336 mandate, a compliant long block assembly (part # ending in qqk) requires extensive fluid flushes, software reflashing, and safety recalibrations that cannot be performed correctly in this window. I suspect a "short block" shortcut was taken, reusing contaminated components in violation of the federal safety remedy. Iii. Fraud by omission & unified safety hazard the dealership is demanding a $99 "diagnostic fee" for an exhaust back-pressure test. Under sc336, testing for "consequential damage" (clogged catalytic converter) caused by the recall defect must be covered by the manufacturer. By omitting the stalling/timing symptoms from the initial techline report, the dealer bypassed the mandatory exhaust safety testing. Reusing oil-contaminated vvt solenoids, camshafts, and valves from the failed engine poses an immediate fire and safety hazard. Iv. Demand for investigation I request NHTSA oversight to ensure classic kia provides: 1. Proof of long block (21101-qqk) installation vs. Unauthorized short block (21102). 2. Time-stamped devt and gds full system scan logs from 3/28. 3. Verification that all contaminated components were replaced, as a partial remedy leaves the vehicle in a hazardous state. Reusing oil-soaked vvt/cams & skipping exhaust tests creates a fire risk. An incomplete remedy violates sc336, leaving the car a high-risk liability for fire & stalling. Information redacted pursuant to the freedom of information act (foia), 5 u. S.

12 Engine And Engine Cooling problem

Failure Date: 03/21/2026

The contact owns a 2021 kia Soul. The contact stated that while driving approximately 40 mph, the vehicle started losing automotive power. The message that the engine was overheating warning was flashing on the instrument panel with an audible chime. The contact pulled over but was unable to restart the vehicle. The vehicle was towed to a local dealer and was diagnosed with engine failure. The contact stated that the VIN was included in NHTSA campaign number: 25v099000 (engine and engine cooling); and was advised by the dealer that the engine failure was not related to the recall, and the dealer refused to perform the recall repair. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was unknown.

13 Engine And Engine Cooling problem

Failure Date: 03/17/2026

Dealer admission of non-compliance: I am updating my complaint to document that kia of streetsboro is officially refusing to perform the mandatory mechanical inspection required by recall sc336. Despite the vehicle suffering from "loss of motive power" (stalling in traffic) and "abnormal engine noise," the dealership’s service department stated via text on March "I asked my manager and he said as of right now since your vehicle passed the tablet we cannot do anything else. " the dealer further stated: "I suggest calling consumer affairs since you have an open case and letting them know what's going on and seeing if they can help. " technical violation: the dealer’s refusal based on a "tablet pass" is a direct violation of TSB sc336, step 18c, which states that if a vehicle exhibits mechanical symptoms that "contradict a pass result," the dealer must open a techline case for further instructions. By their own admission, the dealer is choosing to follow a "manager’s" opinion rather than the federal recall protocol. They are attempting to release a vehicle that is actively stalling at intersections, which they define as an "early warning" system success, while ignoring the actual mechanical failure (the stalling). Safety risk: this is a documented ineffective remedy. The dealer is punting the safety diagnosis to a "consumer affairs" call center rather than performing the borescope and techline escalation required by the NHTSA. I am reporting this dealer for knowingly attempting to return a stalling, unsafe vehicle to a consumer while claiming the recall is complete.

14 Engine And Engine Cooling problem

Failure Date: 03/15/2026

1. Component or system malfunction engine (internal piston/piston ring system) is malfunctioning. The vehicle exhibits clanking noises (“marbles in a can”) and cuts off or stalls unexpectedly while driving. The car is available for inspection by a kia dealer or independent mechanic. 2. Safety risk vehicle loses power while driving, which is extremely dangerous, particularly on highways or in traffic. Stalling while moving poses a risk of collision, loss of steering or braking control, and endangers both driver and others. This makes the vehicle unsafe to drive long distances. 3. Reproduction of problem symptoms have been observed consistently during normal driving and acceleration. Not yet confirmed by a dealer, but the stalling is reproducible during operation. 4. Vehicle inspection the vehicle has not yet been inspected by the manufacturer, dealer, police, or insurance representatives. Immediate inspection is recommended due to engine stall risk. 5. Warning lamps / symptoms clanking engine noise noted prior to stalling. Engine cutting off/stalling occurs while driving. No warning lights illuminated prior to stalling. Symptoms first appeared during recent driving prior to planning transport or repair. 6. Additional notes the vehicle is a candidate for kia engine piston/piston ring recall (sc209 / sc336). Owner recommends urgent inspection and repair to prevent potential engine failure and safety risks.

15 Engine And Engine Cooling problem

Failure Date: 03/13/2026

My 2021 kia Soul is exhibiting a severe safety defect documented in recall sc336: frequent, unpredictable stalling in traffic ("loss of motive power") and audible engine knocking. These symptoms create a high risk of a rear-end collision or being stranded in a dangerous traffic situation. The vehicle is currently at kia of streetsboro. Despite being provided with evidence of these active mechanical failures, the dealership is attempting to "remedy" the safety recall based solely on a "pass" result from the piston ring noise sensing system (pnss) software diagnostic. As the TSB sc336 notes that the root cause is physical damage to cylinder walls caused by defective piston oil rings, a software diagnostic "pass" is not a physical repair and does not address the existing mechanical stalling. I have not received any status updates or communication from the dealership service department since Friday. The dealership is refusing to perform a borescope inspection or open a kia techline case to investigate the stalling, effectively denying a proper safety remedy. I am reporting this as a failure of the manufacturer and dealership to provide a safe and effective remedy for a known life-safety defect. The car remains unsafe to drive.

16 Engine And Engine Cooling problem

Failure Date: 03/11/2026

The contact owns a 2021 kia Soul. The contact stated that while driving at an undisclosed speed, there was an abnormally loud sound coming from the vehicle with the check engine warning light illuminated. The vehicle idled abnormally rough, and the engine was pulsing. The oil level was checked and was noticeably low. The contact added oil to the engine. The vehicle was taken to precision auto care for an oil change. The contact was informed that the oil level was low. The contact informed the technician that the oil had been recently topped off. The contact was informed of the excessive oil consumption. The contact was provided with information on NHTSA campaign number: 25v099000 (engine and engine cooling). The vehicle was taken to the dealer, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced or repaired before the recall repair could be performed. The vehicle was not yet repaired. The manufacturer was made aware of the failure, and a case was filed. In addition, the contact was informed that the vehicle had to be repaired before the recall repair was performed. The failure mileage was approximately 134,431.

17 Engine And Engine Cooling problem

Failure Date: 03/06/2026

Vehicle consistently stalls at complete stops in traffic. After the engine stalls, it requires a manual restart to resume operation. This creates a severe safety hazard, as the vehicle becomes immobile at intersections and in stop-and-go traffic, increasing the risk of a rear-end collision. The dealership is refusing to perform the necessary diagnostic for the engine stalling issue under the havis v. Kia settlement/ksds recall protocols, claiming maintenance gaps, despite the vehicle having 0 open campaigns and the ksds software update previously installed. This stalling issue is a known defect currently under NHTSA investigation (audit query aq23-001) for this specific model and engine.

18 Engine And Engine Cooling problem

Failure Date: 02/20/2026

My 2021 kia Soul is having the same piston issues leading to engine failure as other previously recalled kia Soul vehicles but for some reason my VIN is not part of any recall. Now it has been determined there is heavy scoring in my engine and I will need a new engine. My car is only 5 years old and there should be no reason for such major engine damage. My car has stalled on me while driving and other very similar issues as described on previous recalls. How does NHTSA determine when a certain model/year of car needs to be part of a national recall?.

19 Engine And Engine Cooling problem

Failure Date: 02/13/2026

We are the 2nd owner of 2021 kia Soul bought in July 2025. Took to a dealership for open recalls shortly after purchase. After supposedly passing the piston ring recall (NHTSA 21v259) for the next several months after it had severe oil consumption but other wise drove fine. Then immediately after our last oil change on Feb 13, 2026, less than 10 miles later the car stalled and was knocking badly. Towed to nearest dealership and after diagnostic was told engine needs replacing. Wants us to pay for it. The software update (piston ring noise sensing system or pnss) installed during the recall visit did not fix the faulty piston rings and also failed to give any warning for the impending engine failure. We never had any check engine or oil pressure lights come on until this incident.

20 Engine And Engine Cooling problem

Failure Date: 02/08/2026

The transmission on the vehicle has gone bad twice since we purchased it used. The car has 34,400 miles on it. The problem puts the driver in an unsafe situation as the problem causes the car to lose power while at high speeds. The piston rings have also been replaced as part of the recall. Kia just keeps replacing these parts with more defective parts. I have videos if you want them.

21 Engine And Engine Cooling problem

Failure Date: 01/23/2026

The contact owns a 2021 kia Soul. The contact stated that the engine was running rough, and there was a significant amount of air and oil when the oil cap was opened. Additionally, there was an abnormal sound coming from the exhaust system. The vehicle was sluggish while driving and depressing the accelerator pedal. The wrench warning light was illuminated. The contact stated that the vehicle was taken to the dealer for repair under NHTSA campaign number: 21v259000 (engine); however, upon inspection, the dealer informed the contact that no repair was needed, and the recall was marked as completed; however, the failure persisted. The vehicle was taken back to the dealer, where the contact was advised that there would be a charge for fuel sampling. The vehicle was not diagnosed or repaired. The failure was also associated with NHTSA campaign number: 25v099000 (engine and engine cooling); however, the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was approximately 84,000.

22 Engine And Engine Cooling problem

Failure Date: 01/22/2026

Vehicle is consuming over 2 quarts of oil in less than 1000 miles and it causing the oil light to come on and loss power.

23 Engine And Engine Cooling problem

Failure Date: 01/16/2026

Owner was driving home at the normal posted speed limit when the car stalled out. The check engine light was on along with the oil light, the car cranked back up in time before owner was rear ended. No accident occurred but a close call. The vehicle made it about another 1 mile before stalling again this time losing all control in steering as well and was towed home.

24 Engine And Engine Cooling problem

Failure Date: 01/09/2026

On 01/12/2026, I had my 2021 kia Soul (VIN: [xxx] ) inspected by a technician at j&k automotive after discovering a significant drop in oil. The technician found the engine oil dipstick completely dry. A review of service records shows the last oil change was on 09/18/2025 (odometer: 20,862), meaning the engine consumed nearly its entire oil capacity in just 3,699 miles. The technician confirmed there are no external leaks and no dashboard warning lights (oil pressure or check engine) were illuminated prior to or during the inspection. This lack of warning creates a severe safety risk of sudden engine seizure and stalling at highway speeds. The billing summary noted that the kia Soul with my engine had a potentially defective piton ring design. This failure is consistent with recall 25v-099 (sc336) regarding defective piston oil rings causing cylinder bore scuffing. I am reporting this to document that the piston-ring noise sensing system (pnss) failed to provide an early warning of this safety-related oil consumption. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

25 Engine And Engine Cooling problem

Failure Date: 12/15/2025

The entire car is dead from the engine to the key function completely dead. The car broke down 3 time in the middle of the street which could've caused a serious crash putting my safety and others at risk. The problem has been addressed to two different dealers and kia corporate without resolution. I did make a police report about the mold infestation inside the car. I did now see any warnings prior to the complete reck. The cars been dead from the past 3 months. Both dealers are refusing and/or delaying any type of resolution in fact they gave me even more pressure. Causing me more anxiety than tranquility. Elevating my emotional health.

26 Engine And Engine Cooling problem

Failure Date: 12/10/2025

My kia Soul had a recall for the pistons to be replaced due to faulty pistons. Now they are saying my engine is needing replacement, even with regular scheduled oil changes being done. They said the top was full of sludge. The said it's not covered so I have to pay 6900 plus to get it replaced.

27 Engine And Engine Cooling problem

Failure Date: 11/27/2025

My vehicle is part of an active engine recall related to defective piston oil rings. When I brought my car to the dealership for the recall inspection, I informed them and kia corporate that my car had been stalling and shutting off while driving for months. I have text message documentation of these incidents. This safety concern was ignored. The dealership performed only a basic visual inspection (removing coils and air filter, checking battery, alternator, starter, and attempting to start the engine) and refused to perform a full recall diagnostic or engine tear-down. They claimed the engine was “hydrolocked” and stated that water in the engine “voids any recall” and that outside influence is not covered. I requested that kia corporate dispatch a field service engineer (fse) for an independent inspection, but corporate told me that I cannot request an fse directly and that only the dealership can request it. Since the dealership refuses, corporate will not act. Safety concern: stalling and shutting off while driving is a serious safety hazard that can lead to accidents. The vehicle is part of a federally mandated engine recall, but the dealership and corporate have refused to perform the proper recall inspection. The refusal to inspect the engine or acknowledge stalling incidents leaves me and other potential drivers at risk of unsafe operation. Requested action: investigate the dealership’s refusal to perform the recall inspection. Ensure kia performs a full recall diagnostic, including internal inspection of piston oil rings and related engine components. Require corporate or a field service engineer to review the vehicle given the dealership’s refusal. Address the stalling incidents as a potential safety defect related to the recall.

28 Engine And Engine Cooling problem

Failure Date: 11/10/2025

Auto start stop issue - vehicle will stall and not start when waiting at a red light after you let go of break. All warning lights would turn on and stall.

29 Engine And Engine Cooling problem

Failure Date: 10/22/2025

Description of problem: my 2021 kia Soul experienced complete engine failure consistent with the defect described in recall 25v099 (sc336), which addresses faulty piston oil rings that can cause engine damage, stalling, and potential fire risk. Kia of round rock performed a compression test and found cylinder 3 at 102 psi, well below the normal minimum of 160 psi. Despite this, the service advisor stated in writing that the failure was “unrelated to the recall” and quoted an engine rebuild cost of $7,476. 32. The recall specifically identifies incorrectly manufactured piston oil rings as a cause of engine damage. Low compression from defective piston rings directly aligns with this recall’s description and the findings in my vehicle. Additional detail: prior to the failure, a warning light briefly appeared on the dashboard but did not remain illuminated. It was not the engine light, and it disappeared shortly after. This suggests the defect was developing internally without a consistent diagnostic warning, making it unpredictable and dangerous. Safety concern: this is a serious safety hazard for my family, including our two children (ages 6 and 9). A sudden engine failure or stall could cause a dangerous accident or even be fatal. We trusted kia to provide a safe vehicle and to honor its recall obligations. The refusal to address this under the recall leaves us driving an unsafe car that could fail at any time. Supporting documentation: dealership diagnostic report showing compression test results and repair estimate. Recall notice (25v099 / sc336) identifying the piston oil ring defect. Written communication with kia of round rock and kia consumer affairs. Additional notes: I contacted kia consumer affairs to open a case and request escalation. I am filing this complaint to inform NHTSA that vehicles like mine are being denied coverage for a failure directly related to the recall.

30 Engine And Engine Cooling problem

Failure Date: 10/12/2025

My car experienced engine stall, fire risk, and piston ring failure while returning from a family road trip. Myself, my son, [xxx] old, and [xxx] pup was left in a ditch on a very busy road as the car stalled while driving. My VIN is excluded, however car experienced exact symptoms of recall sc2091. Codes p0300 p0304 p0302 p219d p0303 with no pressure in cylinder 2 and 4. This happened in 0ct 2025 and dealership and corporate do not want to exend goodwill to replace the engine. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

31 Engine And Engine Cooling problem

Failure Date: 10/10/2025

The contact owns a 2021 kia Soul. The contact stated that the vehicle was experiencing excessive oil consumption. The contact stated that while driving at various speeds, the vehicle stalled on several occasions. The driver was able to pull over to the side of the road as possible, and the vehicle was able to restart after an extended time. There was no warning light illuminated. The contact stated that oil was added every two days to prevent the vehicle from stalling. The vehicle was taken to the dealer to be repaired under NHTSA campaign number: 25v099000 (engine and engine cooling), and the dealer deployed the piston ring noise sensing system (pnss) software on the vehicle; however, no further service was performed, and the failure persisted. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the dealer should repair the vehicle; however, the dealer informed the contact that the manufacturer had advised to deploy the piston ring noise sensing system (pnss) software and to only replace the engine if an abnormal sound was present. The failure mileage was approximately 75,000.

The vehicle was taken to the dealer, where an oil consumption test was scheduled to be performed. The contact was asked to provide the maintenance history on the vehicle. The contact was unable to provide the documents, and the dealer refused to repair the vehicle. The dealer reset the code and sent the contact home. The contact stated that on the drive back to the residence, the dtc: p0004 became displayed on the instrument panel. The vehicle was taken back to the dealer. The dealer requested the maintenance records. The vehicle was not repaired. The contact stated that the failure persisted. Most recently, an abnormal sound was coming from the engine, and the vehicle stalled. The contact was able to coast to the side of the road. After several attempts, the vehicle restarted. The failure persisted, and the vehicle remained at the residence unrepaired. The manufacturer was informed of the failure. The failure mileage was approximately 92,000.

34 Engine And Engine Cooling problem

Failure Date: 09/06/2025

New updated testing for recall regarding piston oil rings seems to be faulty. My engine failed with previous testing, which is consistent with the issues my engine is having. However, the new testing claims that my engine has passed even though it is evident that my engine is not in good standing and should have failed. Extreme oil consumption is the number one sign of the faulty piston oil rings, which my car does. I have to add oil every couple of weeks.

35 Engine And Engine Cooling problem

Failure Date: 08/14/2025

Basically since I bought this car back 2020, brand new, the engine loses oil. Vehicle even stalled in the middle of the highway because there was no oil and no warning at all. Kia dealership tells me over and over that there is nothing wrong with it, after doing oil testing for 1000 miles. They have replaced components but nothing has worked so far. Latest issue that after 2700 miles from an oil change, I had to fill it up with oil. Now my car has about 57000 miles on it.
