NHTSA investigations into the 2021 KIA Soul

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

Kia 25V099 Piston Oil Ring Recall Effectiveness

On August 6, 2025, the Office of Defect Investigation (ODI) opened Audit Query (AQ) 25001 to assess the implementation of Kia America, Inc.’s (Kia) remedy program for Safety Recall 25V099, involving incorrectly manufactured piston oil rings which may damage the engine causing a loss of motive power or fire. This AQ was opened in response to consumer complaints alleging of an ineffective remedy, inconsistent inspection results to determine whether an engine replacement was needed, and the unavailability of recall remedies. On August 11, 2025, an Information Request (IR) was issued to Kia reques...

Recalls on the 2021 KIA Soul

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

United States — NHTSA

25V099000

ENGINE AND ENGINE COOLING:ENGINE:HARD PARTS INTERNAL/MECHANICAL

Kia America, Inc. (Kia) is recalling certain 2021-2023 Seltos and Soul vehicles. The piston oil rings may have been manufactured incorrectly, which can result in engine damage.

Risk: Engine damage can cause a vehicle stall or fire, increasing the risk of a crash or injury.

21V259000

ENGINE

Kia Motors America (Kia) is recalling certain 2020-2021 Soul, and 2021 Seltos vehicles equipped with 2.0L Nu MPI engines. The piston oil rings may not have been properly heat-treated, which may result in engine damage.

Risk: A damaged engine may stall, increasing the risk of a crash. In addition, oil may leak onto hot exhaust components, increasing the risk of a fire.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2025083 25,279 units in Canada

Engine

Issue: On certain vehicles, the piston oil rings may not have been manufactured properly and could damage the cylinder walls. As a result, the engine could make abnormal noises, and a warning light may turn on. If you continue to drive the vehicle with these symptoms, the engine could fail. Note: This recall only affects certain vehicles equipped with a 2.0L MPI engine. Safety Risk: An engine failure could cause a sudden loss of power to the wheels and/or increase the risk of a vehicle fire. Both issues could increase the risk of a crash or injury. Corrective Actions: Kia will notify owners by mail and advise you to take your vehicle to a dealership to inspect and, if necessary, replace the engine. The dealer will also install a software that will monitor the engine and warn you if it detects a problem. If you see this warning, you should contact a dealership to arrange replacement of the engine.

Recall 2024549 647,384 units in Canada

Label

Issue: On certain vehicles, the compliance label may be missing information in French. The words listed on the label for "Tires", "Rims", "Front" and "Rear" appear in English only, when they should be listed as "Tires/Pneus", "Rims/Jantes", "Front/Avant" and "Rear/Arriere". Canadian regulations require this information to be listed on the label in both English and French. Safety Risk: These small errors do not affect vehicle safety. Corrective Actions: This is not a recall. Kia has corrected the compliance label for all new vehicles.

Recall 2021225 19,634 units in Canada

Engine

Issue: On certain vehicles, the engine's piston oil rings may be defective. This can cause engine wear that can lead to increased oil consumption. Eventually, this can create abnormal engine noise and the oil pressure warning light may turn on. If you continue to drive the vehicle with these symptoms, the engine could fail. Note: This only affects vehicles equipped with a 2.0 L Nu MPI engine. Safety Risk: A sudden loss of engine power could increase the risk of a crash. An engine failure could also create the risk of a fire. Corrective Actions: Kia will notify owners by mail and instruct you to take your vehicle to a dealer to inspect the engine. The engine will be replaced, if necessary. The dealer will also install a Piston-ring Noise Sensing System (PNSS) software update, to alert the driver of potential damage before an engine failure occurs.

SERVICE BRAKES

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 other drivers if this defect is not addressed. Due to the prolonged loss of use of the vehicle, I am experiencing significant financial hardship and risk to my employment, as I can no longer afford a rental vehicle. I am submitting this complaint so that NHTSA is aware of a potential defect involving brake system failure and non‑functioning collision‑avoidance systems on this model.

SERVICE BRAKES

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.

ENGINE

My 2021 KIA Soul has a recall order for P1327 code which is the knocking noise from the piston ring. The KIA dealership in Idaho Falls is denying the recall order, claiming that it has to be from the upper chamber, not the lower chamber. Which is not stated in the recall letter. They have done everything to avoid this recall. I have evidence that they know the engine have all the symptoms of the piston ring, but trying to avoid everything to replace the engine. They even deny giving the part name that is causing the knocking noise and not giving me the diagnostic report. Even charging $6,000 for the engine replacement.

UNKNOWN OR OTHER

My 2021 Kia Soul has stalled unexpectedly while being driven on multiple occasions. When the vehicle stalls, the engine shuts off and the vehicle loses propulsion, creating a risk of a collision, particularly if it occurs in moving traffic. There have been no warning lights or messages before the vehicle stalls or when the stalling occurs. The vehicle has severe engine oil consumption. After approximately 3,000 miles, the oil level can become so low that no oil is visible on the dipstick. I do not know whether the excessive oil consumption is causing the stalling, but I believe that to be the reason. I previously brought the vehicle to an authorized Kia dealership while it was under warranty because of the oil-consumption problem. The dealership told me that the vehicle was probably leaking oil, that a part needed to be ordered, and that they would contact me when the part arrived. They never contacted me, and the problem was not resolved. I have since reported the repeated stalling and excessive oil consumption to Kia corporate. Kia instructed me to return the vehicle to the dealership for additional testing. I told Kia that I do not feel safe driving the vehicle approximately 40 minutes to the dealership because it has repeatedly stalled while being driven. I asked whether Kia would tow the vehicle, but Kia would not commit to providing a tow. I also asked Kia to put in writing its instruction that I should drive the vehicle to the dealership despite the reported stalling, and Kia declined. The vehicle remains available for inspection. The cause of the repeated stalling is most likely due to burning of excessive oil. I am concerned about an unexpected loss of propulsion occurring again while the vehicle is in traffic.

ENGINE

Vehicle: 2021 Kia Soul LX, 2.0L Engine Subject: Loss of Motive Power and Stall While Driving Under Recall SC336 Description of Incident: On 07/02 @ roughly 6:15PM, while driving on the highway I-35E at approximately 60 MPH, my vehicle's engine experienced a sudden and complete loss of engine power, stalling while in motion. I was able to safely navigate to the shoulder, activate my hazard lights, and restart the vehicle after pulling over. This stall occurred despite the vehicle being covered by Recall SC336 for defective piston oil rings . The recall condition explicitly warns that engine seizure can result in "loss of motive power," creating a significant risk of crash or injury. Ongoing Symptoms (Documented): · Excessive oil consumption: Over 2.5 quarts low after approximately 1,000 miles since the last oil change. This aligns with the recall's "increased oil consumption" warning. · Audible engine knocking when shutting off and ticking during acceleration. This matches the "abnormal noise from the engine" described in the recall. · Active Diagnostic Trouble Codes (DTCs) stored: P0017, P0014, P000B, P0172, P0300, P0301, P0302, P0303, P0304. These indicate timing issues, misfires on all four cylinders, and oil pressure-related failures. Vehicle had similar codes when visited for recall February of this year. Was told everything looked fine. · The vehicle shows signs of instability when accessories (A/C, headlights) are engaged, suggesting the engine is struggling to maintain idle. Safety Risk: The vehicle is unsafe to drive. The stall on the highway presented an immediate crash risk due to the sudden loss of power, which also disables power steering and power brakes.

ENGINE

The vehicle burns oil. The first incident occurred when the car stopped running. Fortunately I was in a residential area and was able to pull into a parking lot. My mechanic confirmed it was lack of oil in the engine. I have taken it to the dealership and had it tested, but they said it was not enough, and then with the recall, they again said it was not the problem. It continues to burn oil and I have to check it at every gas refill to check the level.

POWER TRAIN

I am filing this complaint regarding my 2021 Kia Soul due to repeated engine and powertrain failures and concerns about the quality and safety of the repairs. While my vehicle was under Kia's 100,000-mile powertrain warranty, I repeatedly brought it to the dealership for excessive oil consumption and transmission problems. Despite multiple visits, the dealership performed minor repairs or claimed they could not identify the transmission issue. I also contacted Kia Consumer Affairs but received no assistance. Shortly after my warranty expired, Kia determined both the engine and transmission required replacement. The repairs were completed as a "good faith" repair rather than a warranty or recall repair, using remanufactured components. Since then, I have continued experiencing problems. The replacement engine appears to have been installed improperly, including stripped motor mount bolts/pins and a missing bracket. Within months, I also developed radiator and coolant reservoir problems, raising additional safety concerns. I understand Kia has issued recalls and service campaigns involving similar engine and powertrain defects. When I previously checked my VIN, I recall it showing an engine-related recall. However, a recent search showed no open recalls. Regardless, my vehicle experienced the same failures and required replacement of both the engine and transmission after I repeatedly sought repairs while still under warranty. I believe these repeated failures and the apparent improper installation of the replacement engine warrant investigation. I have repair records documenting my complaints, the repairs, and the continuing issues.

I am filing this complaint regarding my 2021 Kia Soul due to repeated engine and powertrain failures and concerns about the quality and safety of the repairs. While my vehicle was under Kia's 100,000-mile powertrain warranty, I repeatedly brought it to the dealership for excessive oil consumption and transmission problems. Despite multiple visits, the dealership performed minor repairs or claimed they could not identify the transmission issue. I also contacted Kia Consumer Affairs but received no assistance. Shortly after my warranty expired, Kia determined both the engine and transmission required replacement. The repairs were completed as a "good faith" repair rather than a warranty or recall repair, using remanufactured components. Since then, I have continued experiencing problems. The replacement engine appears to have been installed improperly, including stripped motor mount bolts/pins and a missing bracket. Within months, I also developed radiator and coolant reservoir problems, raising additional safety concerns. I understand Kia has issued recalls and service campaigns involving similar engine and powertrain defects. When I previously checked my VIN, I recall it showing an engine-related recall. However, a recent search showed no open recalls. Regardless, my vehicle experienced the same failures and required replacement of both the engine and transmission after I repeatedly sought repairs while still under warranty. I believe these repeated failures and the apparent improper installation of the replacement engine warrant investigation.

The first incident occurred on November 2, 2025. I was driving down a state road. I missed my turn so I pulled into a parking lot to turn around. Once I was able to pull out, I put my foot on the accelerator and felt no resistance. The car rolled out of the parking lot onto the road. I kept pressing the accelerator hoping the gas would return but my car rolled along without picking up speed. I was able to turn into a gas station to get my car off the road. I turned the engine off. When I turned it back on, all of the lights on the dashboard came on, before the only one that remained lit was the check engine light. I had the car towed to my local mechanic who after diagnosing, told me my car over consumed oil which resulted in the engine shut down. I was due for a change in a 400 miles. He said it was a known problem with Kia Souls and advised me to take it to a Kia dealership for inspection, which I did. I've taken it to Kia Danvers. Since 11/2/25, the issue has persisted. On 3/27/26, my car shut down 4 times while driving. Each time I would hear a loud noise coming from the engine, and I could feel the power draining from the steering wheel and pedals before the engine would shut off. After a minute or two, the car would restart. The problems continued on 3/29/26 where it happened 8 times. I was able to get it to Kia Danvers on 4/1/26 for a diagnostic exam and an oil change. They suggested an oil consumption test which I did on 5/4/26. They said my oil reduction was normal. On 5/7/26, while driving, my car began violently shaking with the shaking occurring in the engine. The check engine light came on. I pulled over and immediately called the dealership to explain what happened. The said to come in but I wasn't able to get it towed. When I took it in for scheduled service on 5/27/26, they noted the car consumed a lot of oil and suggested another oil change, and a combustion chamber cleaning.

My vehicle has been in the shop 7 times for misfire in all cylinders over a 2 1/2 year span Kia dealer refused to replace the engine, 8 months after I threatened to sue the dealership for saying they fixed the misfire in all cylinders issue and 8 months later I’m getting misfire in 4th cylinder. As the engine light came on again and I have a high end car diagnostic tool attached to the car which is giving me that code and previous codes of misfire in all cylinders. First misfire in all cylinders started at 16,000 miles bought car brand new and it continued all the way to 37,067 miles . The Kia dealership keep saying it’s this or that and it’s been fixed but the lights come on the previous 7 times after a week or less after taking it home from the dealer and then saying it’s fixed last time I wanted a new engine a Kia representative said it doesn’t need a new engine. I talked to a technician there about reading about this issue in alot of same vehicles he said I was right but Kia doesn’t want to pay for a new engine so they give excuses or just reset or clear the codes which doesn’t resolve the problem , Kia has changed the fuel tank, changed the spark plug wires, the spark plug cables the assembly,ecm which never resolved the problem

I took my 2021 Kia Soul to the dealership for a piston ring recall; they ran their standard test and said it passed, but my car is still showing a misfire fault. I replaced the ignition coil, spark plug, and fuel injector, yet the problem persists. I’ve taken it back to the Kia dealership twice, but they refuse to inspect it because it already passed their test.

On XXX My car was stopped at a light, the vehicle shot down, and would not restart. I had the car towed to Galeana Kia, [XXX]. Upon isnpection at Kia it was found that the engine oil was three quarts low. I was shocked. There had been no warning lights on the dashboard. I had a synthetic oil change 9,000 miles previously. Galeana Kia charged me $315.96. There was a subsequent recall 25V099. "The piston oil ring(s) in your vehicle may have been manufactured incorrectly...This may lead to increased oil consumption..." On April 16, 2025, subject to the recall, Galeana Kia replaced the engine block. I requested a refund of the $315.96 for the work done on November 25, 2024. Galeana Kia refused. Because the repair work done in November 25, 2025 obviously relates to the subsequent recall, I request that you have Kia reimburse me.

The contact owns a 2021 Kia Soul. The contact stated that while checking the engine oil level, the contact noticed that the vehicle was consuming excessive oil. Upon inspecting underneath the vehicle, the contact's husband did not find any leaks. No warning light illuminated. The vehicle was taken to an independent mechanic, where it was determined that the piston oil rings needed to be replaced, and the engine was consuming excessive oil. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 21V259000 (ENGINE); however, the VIN was not included in the recall. The manufacturer was notified of the failure and informed the contact that the VIN was not included in a recall due to the vehicle mileage. The approximate failure mileage was 82,000.

Initial Breakdown: July 2024, my 2021 Kia Soul (under 40,000 miles) idled roughly and stalled while in motion. It restarted, but as a precaution, I towed it to Kia Greenbrier Chesapeake while it was operable. After diagnostics, the vehicle would no longer start. Warranty Denial: The dealer blamed engine sludge from two missed oil changes in 2022 and quoted $10,000 for a new engine. In August 2024, I appealed the decision but was denied (Exhibit A & B). There were no recalls active for the 2021 model at this time, but there were recalls for the 2018-2020 models for identical symptoms. Third-Party Repair: I paid $3,017 out of pocket to an independent shop for a new timing assembly to make the vehicle safe and drivable again (Exhibit C). Because my daughter is disabled and requires transportation, getting repairs was imperative. A new valve kit, fresh synthetic oil, and filter service were completed by the third-party repair shop. I also returned to Kia Virginia Beach for several subsequent oil changes (Exhibit D). In April 2025, Kia Corporate issued an official safety recall for my exact vehicle (Exhibit E). Before that, in March 2025, I attempted to have the newly issued recall (25V-099) performed, but the dealer turned my vehicle away, claiming a lack of parts. Final Failure: In May 2025, the night before a rescheduled recall appointment, the car became permanently inoperable (at only 47,500 miles). Due to extreme financial hardship and health concerns, I am without my vehicle and without an option. Complaint: The Kia dealership refused to perform the safety recall remedy, verbally citing the same 2022 maintenance gaps from the previous year. The dealership violated federal recall regulations for a known defect. I was left stranded, resulting in a financial charge-off of my auto loan.
