The vehicle had a catastrophic engine failure while driving in traffic. The engine would turn over making loud grinding noises but would not start, and the vehicle had to be towed. The engine had only 92,077 miles on it when it failed. Subsequent engine teardown found pieces of the connecting rod bearings which had disintegrated (see attached photos). This failure damaged the piston, crankshaft, valves, and cylinders. This engine has been the subject of a class action lawsuit due to a manufacturing defect of the connecting rod bearings and premature failures in thousands of engines. The engine is part of a class action lawsuit, but we are ineligible for the extended warranty since it had not yet received the knock sensor software update that was required by the lawsuit. However, this software update does not fix the defective connecting rod bearings and only provides a possible warning of an impending failure. I was never notified of this required update. This engine should have been part of a mandatory recall, but instead, KIA chose to release an update that made warranty eligibility impossible for customers who were unaware of its existence. This defective engine is a serious hazard and almost caused a major accident when the engine suddenly failed.

This is a 6 year old car, with just under 108,000 miles. The catalytic converter is clogged, most likely from oil getting past the piston rings and contaminating the catalytic converter. High oil consumption, resulting in 1 qt needed to be added every 850-875 miles on average. Extended warranty company excludes this part. KIA warranty covers exhaust parts only up to 80,000 miles. To replace is $4,100. Car is valued at $3,000-$3500, with dealership saying without replacement car is worth less than $1,000. Other KIA’s in years before and after this vehicle have recalls for this specific issue, and this year car and this vehicle specifically should be added to the recall.

They ended up doing an oil consumption test and my car failed it and mind you they had just put oil in my car the week prior . I took my car Monday because my engine light had came on . When arriving the guy scanned my car with a machine they told me it was bad spark plugs in my engine . He sent me to Firestone because he said the process would be cheaper or faster .( mind you I told them I am doing the oil consumption test) they proceeded to send me to Firestone .firestone checked my oil and that’s when they found out there was no oil in my vehicle .they asked me if I was doing the oil consumption test I told them yes Firestone would not allow me to drive the car back to Kia so I ended up waiting 2 hours for a tow truck . When it got back to Kia they told me I had a bad engine without checking it . They said I don’t qualify for the warranty because I am not the first owner . According the website it said the engine should be good up to 100,000 miles .

The vehicle, a 2019 Kia Soul, is experiencing **severe and abnormal engine oil consumption** requiring frequent, unscheduled oil replenishment. The vehicle has approximately 117,000 miles. **Component or System Failure:** The malfunction is in the **powertrain system**, specifically the **GDI (Gasoline Direct Injection) engine**. The root cause is assessed to be a **structural or design defect** involving the **piston rings**, leading to oil migration into the combustion chamber. The vehicle is available for inspection upon request. **Safety Risk:** This rapid oil depletion poses a severe safety hazard. The engine could suffer **sudden, catastrophic failure** due to oil starvation while operating at highway speeds. Such an event would cause an immediate loss of power and control, placing the occupants and surrounding traffic at significant risk of a serious accident. **Prior Symptoms:** The primary symptom is the **consistent, rapid drop in the measured oil level** observed between scheduled maintenance intervals. **No prior warning lamps, messages, or fault codes related to low oil pressure** appeared before the issue was discovered and confirmed by the owner through monitoring the dipstick. **Manufacturer Inspection/Response:** The manufacturer, Kia America, has **refused to conduct a technical inspection or acknowledge the defect** across multiple documented case files (Case #XXX, #XXX, #XXX). The manufacturer has stated a policy of non-assistance due to the vehicle being outside the standard warranty period. This lack of investigation, despite the serious safety risk, is the basis of this report. This issue aligns with widely documented **structural defects** in the manufacturer’s GDI engine line. The current safety risk necessitates immediate federal review.

Vehicle: 2019 Kia Soul 2.0L GDI VIN: [XXX] Mileage: 92,200 The engine and connecting rod bearings failed — a known defect in Kia’s Theta II GDI engines. The vehicle began making a loud knocking noise and would stall when turning to start the engine within days of purchase. This is consistent with the same defect addressed in Kia’s KSDS / PI2107 Product Improvement Campaign and Theta II Engine class-action settlement. Component failed: Engine. The engine is available for inspection. Safety risk: The engine stalls unpredictably, creating a major risk of collision or being stranded in traffic. The stalling has occurred more than once, and the car is unsafe to drive, per Moritz Kia. Confirmed by: Moritz Kia Fort Worth, which diagnosed internal engine failure and quoted $6,230 for replacement. Kia Consumer Affairs refused to open a case or perform the recall, claiming it was “past due,” though the vehicle is within the 15-year/150,000-mile lifetime warranty coverage. Maintenance history: CARFAX confirms regular oil and filter changes, most recently on 05/30/2025, proving the vehicle was properly maintained. Inspection: Completed by Kia dealership; no outside inspection yet. Warning symptoms: Engine knocking and stalling Summary: Kia is refusing recall service and case creation despite this being a known manufacturing defect, not a maintenance issue. The KSDS system only detects failure after it occurs and does not fix the defect. This creates a continuing safety hazard for consumers.

Got it too a repair shop waiting to hear Monday exactly all the damage but they did say it had no oil in the car. It’s only been 2 1/2 months since an oil change checked that last month had plenty of oil could this be related to the 2021 to 2023 engine oil burning and KIA. I have been towed on the last three or four oil changes that it was almost a half a quart low each time.

1DP22003 · Loss Of Motive Power
Opened Sep 12, 2022 · Closed Dec 12, 2023
Status: closed (inferred from source dates) · Engine
The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. Additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. The petition itself can be reviewed at NHTSA.gov under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitioners’ request. The Petitioners have provided additional complaints within four supplemental letters dated January 31, 2023, March 21, 2023, May 23, 2023, and August 4, 2023. ODI’s evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to NHTSA which referenced either the oil drain plug or a crack in the oil pan. After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into the oil drain pan assemblies of the subject vehicles. Based on a review of the available information, a loss of motive power resulting from an oil drain plug back out has not occurred between the initial sale of a vehicle and the completion of its first oil change. If during an oil change service, a technician fails to remove the existing drain plug gasket before installing a new gasket, it is likely that a proper seal between the drain plug and the oil pan will not be made. An improper seal between the drain plug and oil pan could lead to the backing out on the drain plug, resulting in the sudden loss of oil while driving. Additionally, the provided examples of oil pan cracks were localized to the immediate vicinity of the oil drain plug and/or appeared to be the result of direct-contact with a tool during servicing. There is no information to support that a vehicle-based defect exists relating to the oil pan assembly, and instead the documented incidents are related to the failure to follow the proper maintenance procedures during oil change service. In October 2023, Hyundai published a Technical Service Bulletin (TSB) that provided detailed instructions for oil change service on its gasoline powered vehicles, specifically highlighting the need to remove and replace the existing drain plug gasket prior to reinstalling the drain plug. After a thorough review of the material submitted by the petitioner, the information already in NHTSA's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, NHTSA does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA’s reasons for denial of the petition will be published. The reference numbers for the complaints to NHTSA cited by the petitioner can be found in the petition submission documents in the public file for DP22-003. To review those complaints and the additional complaints ODI added to its evaluation which are cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
