I own a 2021 Kia Soul (VIN: [XXX] ). It is under Safety Recall SC209. The engine has failed TWICE due to this defect (stalling in traffic). The dealer (Ourisman Kia) and Manufacturer (Kia America) are refusing to provide a safe loaner vehicle while they inspect it, leaving a 100% disabled veteran stranded. I am reporting a failure to remedy a safety defect in a reasonable time. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2021 Kia Soul. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated, and the engine seized. The contact stated that nearby drivers assisted with pushing the vehicle to the shoulder of the roadway. The failure had occurred while driving on a busy highway. While attempting to restart the vehicle, the vehicle started; however, it was unsafe to drive the vehicle. The vehicle was towed to the dealer, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. Prior to the engine seizing, the vehicle was consuming an excessive amount of engine oil. The contact stated that 3 to 4 quarts of oil needed to be added between oil changes. In addition, the contact stated that in 2021, the vehicle was repaired under NHTSA Campaign Number: 21V259000 (Engine). The contact stated that after the recall repair was performed, the excessive oil consumption started. The manufacturer was not made aware of the failure. The failure mileage was approximately 88,200.

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.

The contact owns a 2021 Kia Soul. The contact stated that while driving at various speeds, the engine was consuming an excessive amount of engine oil. While depressing the accelerator pedal, there was an abnormal sound coming from the engine. The vehicle was not taken to the dealer or an independent mechanic to be diagnosed. The contact was topping off the engine oil bi-weekly. The contact related the failure to NHTSA Campaign Number: 25V099000 (ENGINE AND ENGINE COOLING) for which the VIN was included. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 150,000.

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

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.

The contact owns a 2021 Kia Soul. The contact stated that while driving at an undisclosed speed, there was an abnormal rumbling sound coming from the engine with the check engine warning light illuminated. The contact had received notification of NHTSA Campaign Number: 25V099000 (Engine and Engine Cooling). The vehicle was taken to the dealer, and the contact was informed that the vehicle failed the inspection test for the recall. The contact was informed that the PNSS software was installed, and the check engine warning light was reset. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the dealer, where it was diagnosed with engine failure. The contact was informed that the engine needed to be rebuilt or replaced. The vehicle was not repaired. In addition, the contact was informed that the engine failure was caused by the recall repair. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was filed.

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.

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.

My car had sputtered leaving gas station I took it to my mechanic February 17 had engine coil and spark plugs replaced There was a anti theft recall for software update I took my car to Kia dealer and they preform the update As I was waiting I looked up my vin for any other recalls and there was one but letters would not be sent out till April 4 2025 On May 10 th my car had loss power and on the 12 th I called Kia and they said there was a recall for sc336 piston oil rings I took my car in on May 17 they did a software update 2 days latter my car was making a knocking sound I had that repaired by my machanic on May 20th I received a email from Kia reference a up date to the recall and says my car will be fixed with no charge I spoke with a Kia representative and out in a claim for reimbursement but was denied….

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 burns oil irregularly and quickly. In October 2022, the check engine light was on and stalled while driving. Kia dealership in Sioux City stated my vehicle was not part of the original recall. The car was under warranty and they kept it for nearly 2 months to repair. Vehicle started stalling again last winter. Was told mice ate wires per dealership. In June 2025 - oil still burning quickly despite getting on time and regular oil changes. This time while driving on the interstate the check engine light came on again. Went to my local mechanic immediately (Car is out of warranty per mileage 85,000) and I hate the dealership - bone dry oil. They are convinced it's the pistons. Called the dealership. They made me call Kia. Kia claims my vehicle is not effected by the updated April recall - but they could repair my...horn. This car is dangerous. It constantly makes a knocking sound. I check the oil twice a week and have to add oil accordingly like it's a 1978 Buick. If this car stalls out while I'm commuting to work on an interstate, I and others could be seriously injured.
