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 c

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 ens

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.

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 17: "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 attemptin

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.

I am filing this complaint to report a serious safety failure involving the service braking system and the failure of Forward Collision‑Avoidance Assist (FCA) and Automatic Emergency Braking (AEB) on my 2021 Kia Soul. During an imminent collision event, the vehicle failed to brake as expected, and FCA/AEB did not activate, despite conditions that should have triggered emergency braking. This created an extremely dangerous situation and placed me and other motorists at risk of serious injury or death. The vehicle is currently subject to an active recall and has now been inoperable at the dealership for approximately one month under the lemon law process. The failure involved federally regulated safety systems, not supplemental or convenience features. I reported this incident to Kia America Customer Care, but the manufacturer has declined to conduct a manufacturer‑level safety investigation unless I personally pay for removal and shipment of the ACU/Event Data Recorder (EDR). Kia America has also declined to provide any transportation assistance while the vehicle remains unsafe and inoperable and has referred the matter back to the dealership and my insurance instead. Kia America has stated in writing that they rely solely on dealerships for diagnosis and repair and that they will not investigate further unless I incur additional costs. This refusal to independently investigate a braking system failure raises serious safety concerns, particularly given the potential risk to ot

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.

Check engine light on due to catalytic converter, took it to Kia motors in Bakersfield, California due to recall let them know that there was a check engine light on after buying the vehicle and only having it for one month and I thought it was due to the recall, which was on oil, piston rings, the dealership stated I could give all my paperwork that I had in regards to that, and if the engine failed, they would take care of it. After the test for the recall was done the engine failed and then a few days later a new updated recall, came out where the engine had to be running hot for the test to be done and then my recall passed so nothing was ever fixed with my vehicle. I believe that the catalytic converter is bad due to oil running into or around the catalytic converter. I also believe due to the malfunction of the oil, piston rings being bad/malfunction or whatever the recall was on is a determination of why my check engine light is on stating it’s a catalytic converter I believe if I continue driving my vehicle in the condition that it’s in it eventually will catch fire due to the issue.

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?

Description of Incident: On February 13, 2026, at approximately 3:00 PM, I was driving my 2021 Kia Soul (VIN: [XXX] ) on Calvine Road in Elk Grove, CA. A vehicle suddenly merged into my path. I immediately attempted to apply the brakes, but the pedal failed to depress or engage normally. Despite the imminent collision, the Forward Collision-Avoidance Assist (FCA) failed to provide any alert, and the Automatic Emergency Braking (AEB) system did not activate. To avoid a high-speed rear-end collision, I was forced to perform an emergency steering maneuver toward the curb and into roadside bushes to stop the vehicle. This maneuver resulted in severe mechanical failure, including a broken driver-side axle, damaged rims, and broken brake pads. The dealership (Elk Grove Kia) has provided an estimate of $9,461.67 for these repairs but has failed to explain why the primary safety systems and service brakes failed to function as designed during this emergency.

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.

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.

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.

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.

My vehicles engine light is consistently flashing on and off, indicating there is an engine issue and when I took it to get the engine light diagnosed, error code P1327 shows up and the mechanic sites that it could be related to the faulty piston ring part, which is corresponding to the recent recall of Kia Souls from last February. Not to mention my vehicle sometimes goes through a momentarily power surge or lack of that temporarily stalls the engine.

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.

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.

Sunroof failure, spontaneously exploded. Fortunately I was not driving the car when it happened or could have caused an accident. Went to my car one morning and the sunroof looked like an earthquake for no reason. No damage, car was parked my driveway and was definitely not vandalism. Dealer said to contact Kia directly and report the incident to them because they would get nowhere with the factory and I should contact them. I also had a left front drivers door glass break that I originally thought was vandalism but nothing penetrated the glass, no rock or anything found and 2-3 video cameras I reviewed many time and not see anyone breaking the window. Makes me think it is the same problem with some kind of defective glass.

In November 2024, I was having issues with oil consumption and my car stalling while driving. I took it into Bob Sight Kia and explained that I'm constantly having to change or add oil to my car. They ran diagnostics and "fixed" the issue without any requests of maintenance records. The very next day after I picked it up, my oil light came on. I changed my oil November 2024, January 2025, March 2025, April 2025, May 2025. On May 10, 2025, while driving back from a family emergency, my transmission went out. I had it towed to Bob Sight Kia and was told the transmission would need replaced and it is under warranty, they did not request maintenance records then either. The transimission was replaced and I picked up my vehicle on June 5, 2025. My car started stalling again July 2025 and August 2025, I changed the oil each time. I took it back to Bob Sight Kia and was told I needed to provide maintenance records this time. I provided receipts of the above dates I changed my oil but was told my claim is being denied due to not having maintenance records from 2022 and 2023. I have called Kia Consumer Affairs and Bob Sight Kia. The general manager at Bob Sight Kia told me my car had been misdiagnosed in November 2024. I have explained to Kia Consumer Affairs exactly what I have been told by the dealership but they still refuse to replace the engine. My car currently has 73k miles and I am having to change my oil every 1500 miles. I believe my vehicle is under the engine recall and Ki

We are experiencing problems consistent with the issues identified in recall SC336, which pertains to defective piston rings potentially leading to increased oil consumption and engine damage. Specifically, for an extended period of time we have encountered significant oil consumption, the check engine light turning on repeatedly, engine overheating, and abnormal temperature gauge readings. Additionally, our vehicle has stalled multiple times while driving, lost power, and exhibited jerky acceleration, along with strange noises from the engine. These stalling incidents, in particular, were extremely frightening and created unsafe conditions on the road for our traveling family. We previously contacted members of Kia’s corporate office in early April 2025 (we can forward email), but unfortunately, we initially never received a response from Kia with respect to our email. We brought our vehicle to Wesley Chapel Kia for the recall service on June 9th; however, no repairs were made. Our engine was not replaced. We were told our vehicle passed the vibration test, which we find insufficient. The check engine light returned shortly after the visit to address the recall. We are aware that Kia changed the procedure for the recall inspection after the initial recall was announced. We have read accounts online from other Kia owners whose vehicles originally failed the recall inspection and were due for engine replacement—only to pass under the new testing protocol.

In May 2025, my 2021 kia soul engine suddenly seized while I was driving close to my home. I took it to my local Kia dealership to have it inspected in which they said my engine needed to be replaced but did not identify exactly what caused my engine to fail. I have not had any issues with my car before this happened and kept up with oil changes, etc.I also told the service department about the recent recall on my vehicle regarding faulty piston rings leading to engine failure. Due to not having an extended warranty, I was told the replacement would be around $10,000. I reached out to them Kia Customer care to see if they could provide assistance considering this was something I did no t expect to happen. I decided to have it towed to a mechanic my family knows and he had my engine rebuilt for lower cost. Today (8/21/2025), we picked up the car which started out good initially but still demonstrated the same issue with the engine failing after driving it one time. My VIN is not in the recall list but I am not understanding how my vehicle which was performing perfectly, all of sudden seized on me. Prior to my engine failing, there were no dashboard indicators that anything needed to be inspected. They appeared after the engine seized. Fortunately, when my engine seized, I just turned into my neighborhood but I'm sure if I was a couple seconds or minutes late, my safety would have been at risk considering I live off a busy highway.

NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own. What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
