ENGINE AND ENGINE COOLING
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.

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.

Vehicle Information: Make/Model/Year: 2021 Kia Soul VIN: [XXX] Odometer: [96,000] Dealerships: Kia of Killeen, TX /Kia of Round Rock, TX & Component/System Failure: Engine failure due to defective piston oil rings, causing low compression and stalling. Components are available for inspection at both dealerships. Safety Risk: Sudden engine failure and stalling created a serious risk to my family, including children ages 6 and 9. The defect could cause loss of vehicle control or fire, potentially fatal. Dealer Confirmation: Kia of Round Rock confirmed low compression (Cylinder 3 at 102 PSI). Kia of Killeen falsely stated the recall was completed; while the car was in their care, it would not crank. Inspections: Vehicle inspected by Kia dealerships. No police or insurance inspections. Kia Consumer Affairs contacted for escalation. Warning Signs: A brief dashboard warning light appeared (not engine light) before failure and disappeared quickly. Vehicle experienced stalling while attempting recall repair in February/March. Problem Description: Failure is consistent with Recall 25V099 (SC336) for faulty piston oil rings. Kia of Round Rock confirmed low compression, but the service advisor stated it was “unrelated to the recall” and quoted a $7,476.32 engine rebuild. Supporting Documentation: Dealership diagnostic reports and repair estimates ( From RoundRock) (Killeen:Pending) Recall notice (25V099 / SC336) Written communication with Kia dealerships and Consumer Affairs Additional Notes: I contacted Kia Consumer Affairs to open a case and request escalation. Filing this complaint to inform NHTSA that vehicles like mine are being denied coverage for a defect directly related to the recall.

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.

ENGINE AND ENGINE COOLING
The contact owns a 2021 Kia Soul. The contact stated that the engine was making a grinding sound while the vehicle was being started. Additionally, the contact stated that the engine oil had to be changed every week. While receiving an oil change, the contact was informed that the engine seemed to be defective, and the contact was referred to the dealer for assistance. While the vehicle was idling at a red light, the vehicle suddenly stalled without warning. The contact shifted to park(P) and made two attempts to restart the vehicle before being able to continue driving. While decelerating to come to a stop at a red light, the vehicle stalled a second time. The contact shifted into park(P) and several attempts were made before the vehicle restarted. There was no warning light illuminated. The contact received notification of NHTSA Campaign Number: 25V099000 (Engine and Engine Cooling). The vehicle was taken to the dealer who had installed the piston-ring noise-sensing system software and determined that the remedy was completed, and that the engine did not need to be replaced. The dealer also informed the contact that the heck engine warning light had failed but had been repaired and should properly illuminate whenever needed. The manufacturer was not informed of the failure. The failure mileage was unknown.

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.

VISIBILITY/WIPER
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 Kia will not honor it

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. This shift in procedure was never explained to us during our recall appointment, and we have serious concerns about the effectiveness of the updated remedy program. The lack of transparency and the unresolved issues with our vehicle leave us deeply dissatisfied and looking for answers. We are seeking assistance in understanding what steps we can take to ensure the safety and reliability of our vehicle and to hold the manufacturer accountable for following through on their recall commitments.

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.
