  • 2021 KIA SOUL
    - Worcester, MA

    In late 2024 my vehicle, a 2021 KIA SOUL, stalled 3 separate times as I was driving, one of which I was driving in traffic, going about 10 mph, about mid-December. There were no warning lights that came on. I made an appt. with a KIA Service Dept. for Jan. 2025 (earliest available) I did not drive the vehicle in the interim. The KIA Service Dept. said that the problem could be low oil pressure, and performed an oil change. In April of 2025 I received the safely recall for a piston oil ring defect in my vehicle. I promptly called "Ron Bouchard KIA" in Leominster, MA, and brought the vehicle there April 16. They performed their tests which my vehicle failed. They initially said a new engine is being ordered for my vehicle, and it could take 2 to 3 weeks. Now, after 5 weeks, It appears they may not replace my engine after all. (!?!?) They stated that KIA Corporate sent out a directive that these recalled vehicles be retested. My concern is a real safety concern, especially with the stalling in traffic, which is a real danger for all. My experience of stalling in traffic, is just as described in the safety recall itself, and I do not wish to drive a vehicle that may catch on fire some day!!!

    Our 2021 Kia Soul experienced complete engine failure without warning. The engine suddenly lost power and became inoperable while driving. The dealership's diagnostic testing identified a camshaft sensor code, but no definitive cause for the catastrophic failure was provided. We believe the failure is related to internal engine damage potentially caused by defective piston oil rings, consistent with NHTSA Recall Number 25V099000. Kia has not conducted a full internal engine inspection to rule this out. The vehicle is in Kia's possession and is available for inspection upon request. The sudden engine failure occurred without warning and caused a complete loss of power while the vehicle was in motion. This could have led to a serious accident had the incident occurred in heavy traffic or on a high-speed roadway. The inability to accelerate or maintain control of the vehicle poses a serious safety risk to both the driver and others on the road. Yes. The vehicle was inspected and diagnosed by a Kia dealership. While they identified a camshaft sensor code, they did not perform a full inspection to determine the internal cause of the engine failure. They declined to attribute the issue to the known piston oil ring defect and refused to repair it under the recall. Instead they want to submit it to the TechLine for the power train warranty. We had to spend hours calling places and collecting information of all oil changes and maintenance on the vehicle over the last 4 years. We can show a CLEAR pattern of regular maintenance of the vehicle. The vehicle has been inspected by an authorized Kia dealership. No inspections have been conducted by the police, insurance representatives, or other third parties. There were no warning lamps, dashboard messages, or performance issues prior to the engine failure. The vehicle was regularly maintained and had been operating normally up to the point of the incident.

    I own a 2021 Kia Soul that was serviced under recall SC060, which involves inspection of the piston oil rings for potential defects. The recall service was performed at an authorized Kia dealership on May 12th, and I was informed that the engine passed the inspection and was operating properly. However, on [XXX] after the recall service was completed, I noticed oil deposits on my spark plugs. Upon removal and inspection, the spark plug tips (combustion side) show clear evidence of oil contamination, which suggests that oil is entering the combustion chamber—exactly the type of problem SC060 was meant to address. My car is definitely damaged, and my recall passed the inspection. That doesn't make sense. Kia Dutch Miller didn't give me proof of inspection of my car; they only gave me the invoice for the work done on the car. I have photo evidence of the oil-contaminated spark plugs, and I am concerned this may lead to increased engine wear, misfires, or even total engine failure. Please investigate whether recall SC060 is being resolved properly by dealerships, and whether additional remedies or extensions should be provided to affected owners like myself. My car hasn't been fixed yet. Vehicle VIN: [XXX] Mileage at time of recall service: 41,365 Date of recall service: [05/12/2025] Location of dealership: Dutch Miller, South Charleston, WV Thank you.

    Hi, I had my car tested for recall SC336, and it initially failed, indicating the engine needed replacement. The dealership ordered a new engine from Kia. However, a few days later, they called to say that after retesting, the engine was fine and didn't require replacement. Now, I'm experiencing excessive oil consumption, and the check engine light shows code P0420, indicating a faulty catalytic converter. This issue is likely due to the car burning oil, clogging the converter, and pointing to a problem with the piston rings – the same issue covered under recall SC336. Given the recall's warning of potential engine stalling and fire risk, I'm extremely uncomfortable driving this car.

    I purchased vehicle in Nov 2025 from Autonation. It drove well for awhile, but once I drove steadily for several miles, the steering wheel started drifting back and forth, rather like it was driving itself. I was in on the 2025 recall for the piston issue, and failed the first test; apparently passed Kia's "new test". While at the dealership, they did an alignment and told me my problem was solved; I asked if they had test driven it, and had let the previous service rep, named Ken, know that it started after a period of driving, not come and go driving in town. I asked if they had test driven they car, they assured me they had but I don't know if they drove it any distance. On the way home, the steering wheel again shifted back and forth in as I drove a secondary road home that had long distances between intersections.

    I was told that my engine failed the test for the recall for the incorrectly manufactured piston oil rings and that they would have to replace my engine. It has been turned in at the Shawnee-Mission KIA dealership since April 23rd and they said it would only take 2 weeks. I called again today at 5/5/2025 and now they are saying that repair is held indefinately and I have chemotherapy appointments that I have to show up for and they told me they do not loan cars out so I can have a means of transportation. I am given no specifics as to why this is happening. This is unacceptable.

    On [XXX] Car stopped during traveling home on [XXX]. Had car towed to Stapleford Auto in St. Georges, Delaware. The mechanic found that the motor had seized. I Called KIA Customer Care and was advised to tow to the KIA dealer in Felton, Delaware. Dealer had the car from 2/26/25 and did not inspect the car until approximately 3/11/25. During the interim I discover a recall for model year 2021 due to faulty piston rings which was shown to cause engine seizures. When contacted by KIA dealer they claimed the problem was due to lack of Maintenace. I have documentation detailing the Maintenace of the car. I have contracted KIA customer care on several occasions stating that Maintenace was done and expected KIA live up to the recall notice. So far, no response. I contacted the Delaware Attorney General, and they told me to contact you folks. KIA Case#: [XXX] I appreciate any assistance in the manner. Thanks, [XXX] Email: [XXX] Cell: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
