Johnson Ave, El Cajon, CA 92020 SYMPTOMS: Rapid oil consumption, abnormal engine noise, overheating, vehicle stalling at complete stops, difficulty restarting. All symptoms are explicitly documented in SC336 TSB (Rev 6, 10/21/2025) as consequences of defective piston oil rings. DEALER CONDUCT ISSUES: 1. CHARGED $280 DIAGNOSTIC FEE TO PERFORM A RECALL. Owner confirmed open recall on VIN before arrival. Dealer required $280 diagnostic payment as condition of recall service, in violation of 49 U.S.C. 30120. 2. 24-HOUR TSB PROTOCOL VIOLATION. SC336 TSB requires engine vibration inspection no sooner than 24 hours after R/O open date. R/O opened May 16 at 7:38 AM. Inspection report also dated May 16 with no timestamp. If test ran same day, PASS result is invalid under Kia's own guidelines. 3. FAILED TO OPEN REQUIRED TECHLINE CASE.

ENGINE
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.

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.

ENGINE, FUEL/PROPULSION SYSTEM
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.

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.

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: 3/17/26: Recall repair performed (software update only) 3/29/26: Engine failed catastrophically 4/2/26: Second dealership confirmed failure related to recall defect

VISIBILITY/WIPER
Manufacturer defect: Massive paint delamination/adhesion failure on the roof. Large sheets of paint are flaking off while the vehicle is in motion, creating a debris hazard for following drivers and distracting the operator. The failure has exposed the bare metal structure, which may lead to premature rusting.

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)
