ENGINE, ELECTRICAL SYSTEM
**Vehicle:** 2018 Kia Soul\ **Mileage:** Approximately 198,000 miles 1\. What component or system failed or malfunctioned, and is it available for inspection upon request?** The engine appears to have experienced a serious malfunction, and the vehicle is no longer moving. I believe the engine may have failed. The vehicle is available for inspection upon request. 2\. How was your safety or the safety of others put at risk?** There is no immediate safety risk at the moment because the vehicle is not being driven. However, an unexpected loss of engine power or the inability to move could create a dangerous situation if it occurred in traffic. 3\. Has the problem been reproduced or confirmed by a dealer or independent service center?** No. The vehicle has not been inspected or diagnosed by a dealer or independent service center. The exact cause of the failure has not been confirmed. 4\. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others?** No. The vehicle has not been inspected by the manufacturer, police, insurance representatives, or any other party. 5\. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear?** The check engine light came on, and the vehicle showed misfire codes for cylinder 1 and cylinder 3, along with an oxygen (O2) sensor code. The vehicle was also producing a significant amount of white smoke from the exhaust. These symptoms occurred before the vehicle stopped moving. The exact cause has not yet been determined because the vehicle has not been professionally inspected.

ENGINE
I am reporting excessive engine oil consumption in my 2018 Kia Soul, VIN [XXX], with over 150,000 miles. The engine consumes approximately 1-2 quarts of oil every 1,000 miles. There are no visible external oil leaks, and the vehicle does not produce visible exhaust smoke. I am concerned that this excessive oil consumption may indicate an internal engine defect and could lead to engine damage or sudden engine failure if the oil level becomes too low . Having to add oil so frequently creates an ongoing risk that the engine could become dangerously low on oil between checks, potentially resulting in engine failure while driving and creating a safety hazard for the driver and other motorists. I contacted Kia America to report the problem and request assistance with diagnosis and engine repair or replacement. Kia reviewed my VIN and stated in writing that there are no applicable oil-consumption recalls, service campaigns, or warranty extensions for my vehicle. Kia also denied my request for goodwill assistance. I am concerned that this problem may affect other Kia Soul owners and believe it warrants further investigation. I am submitting this complaint so that NHTSA can document the excessive oil consumption and determine whether further investigation is warranted INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE, UNKNOWN OR OTHER
My car has very high oil consumption. I regularly take it for oil changes and have never missed an oil change. In between oil changes I need to put anywhere between 2-3 bottles of oil in. I have taken it in to the dealership for a couple of oil consumption tests that both failed step one so they kept it overnight and did some kind of flush or cleanse and then it passed step 2 both times. The car is good for a little while and then it starts consuming alot of oil again. Due to the high consumption of oil my catalytic converter is going bad and the engine seems very sluggish at times. I do have a yellow check engine light constantly on and the code is for the catalytic converter due to high oil comsumption. The dealership told me they can't do anything about the warning light until it starts to flash yellow instead of being solid yellow. I brought it into the dealership for that and they acknowleded my year make and model are known for excessive oil consumption which can cause the catalytic converter to go bad. They won't do anything about it because it passes step 2 of oil consumption test. but they keep giving me a hard time about just permanently fixing it under the warranty since it passes step 2 even though I am back months later for the same problem. I feel they are trying to run my warranty out so they won't have to fix it. My car now won't pass an emissions test because of the catalytic converter.

ENGINE, ELECTRICAL SYSTEM
The vehicle is suffering from an extreme internal engine oil consumption defect, burning approximately 3 quarts of engine oil every 500 to 600 miles with no external leaks. The internal oil burning heavily fouled the vehicle's ignition system (spark plugs and coil packs), causing severe engine misfires and a sudden vehicle stall while operating in motion on public highways. This unexpected loss of motive power creates an extreme safety hazard. The local dealership, Paramount Kia of Hickory, refused to follow proper factory Technical Service Bulletin (TSB-ENG219) testing protocols to document the defect, leaving the consumer operating an unsafe vehicle.

My 2018 Kia Soul has failed on oil consumption test and needs and engine replacement. Kia knows of these issues with these cars but will not cover the engine replacement cost bc the class action suit does not cover oil consumption failure only rod bearings. This will be an issue sooner or later with the oil problem. Kia has several recalls on other vehicles for the exact same thing.

POWER TRAIN
The contact owns a 2018 Kia Soul. The contact stated that while driving at 45 MPH, the vehicle stalled and jerked while accelerating and experienced severe jerking while decelerating. The failure had occurred on several occasions. On June 18, 2024, the vehicle failed to accelerate or shift properly. On January 15, 2025, the vehicle shuddered violently and nearly stalled. On April 14, 2026, the vehicle was jerking, and the transmission shifted gears improperly. The vehicle was taken to a dealer, and observed that the vehicle was consuming oil excessively. The dealer replaced the spark plugs and performed an induction cleaning and transmission valve service. The dealer was unable to duplicate the failure after a 36-mile test drive, after the service. From May 27 to May 29, 2026, the vehicle failed to start and was towed to the dealer again, where a new short-block engine assembly was installed. On June 2, 2026, a technician discovered that there was no oil in the engine, resulting in a critical crankshaft failure code. Despite the short block replacement and oil correction, the powertrain failures persisted, and the vehicle failed to exceed 50 MPH. The vehicle violently stalled and jerked while accelerating and decelerating, creating a safety hazard. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 92,573.

ENGINE, POWER TRAIN
On [XXX], my 2018 Kia Soul (VIN [XXX] ) displayed DTC P1326 with a blinking check engine light and went into limp mode. Ray’s Automotive documented P1326 in writing, added oil, and cleared the light only to allow safe transport. At Greenway Kia (Avenues), they charged $199 and refused to create a Vehicle Diagnosis Number (VDN) or perform the Bearing Clearance Test (BCT) unless they could reproduce the code. This directly contradicts Kia TSB PI2107Y/Z (Rev 1, 11/07/2024), which states: “A Vehicle Diagnosis Number (VDN) must be created with or without DTC P1326, after scanning for DTCs, prior to performing PI2107Y/Z.” Ray’s found low oil, but my next scheduled oil change was still 300 miles away. I refused to accept the vehicle back because limp mode is unsafe for my daughter (primary driver). The dealer recently told me to pick it up anyway. Kia Corporate opened Case #[XXX] after 2 separate 2-hour Kia recorded calls on June 1 and June 3, 2026, but continues to refuse the required diagnostic. This is a known manufacturing defect covered under Kia Product Improvement Campaign PI2107 and the class-action engine settlement. The refusal creates a serious safety risk for my daughter and family. Requested Action: Require Kia to follow the published TSB (VDN creation and Bearing Clearance Test with or without active code) and provide a rental vehicle.

FUEL/PROPULSION SYSTEM, ENGINE, ELECTRICAL SYSTEM
I am writing to report safety concerns regarding my 2018 Kia Soul Plus. I have been experiencing several engine issues, including knocking noises, hesitation during acceleration, excessive oil consumption, and an active check engine light. Recently, while driving with my daughter, the vehicle began shaking and the check engine light flashed three times. Although I strictly adhere to the recommended maintenance schedule, these issues persist. My mechanic identified code P0455, but a smoke test did not reveal a leak. Additionally, despite having a full tune-up in August [2025] at 105,636 miles, I am being told I require another tune-up due to engine misfires. I am concerned about the frequency of these repairs and the overall safety of the vehicle’s engine.

ENGINE
My 2018 Kia Soul with the 2.0L Nu GDI engine is experiencing severe oil consumption of approximately 1 quart every 300–400 miles. The engine and lubrication system are available for inspection upon request. My check engine light is currently on. The dealer performed several recalls on the vehicle, including PI2107 (KSDS), SC226, and CS2311A, but refused to perform the required oil‑consumption test described in TSB ENG 222 (Rev 8). The service technician stated that because the oil‑consumption test is “not on the VIN,” they would not perform it under warranty. I was told I could pay $250 out of pocket for the test, but that even if the test confirmed a defect, the dealership would not cover any repairs. I was also told to “run the car until the motor seizes up” before they would help. This instruction is unsafe and contradicts Kia’s own safety systems, including KSDS, which is specifically designed to prevent engine seizure while driving. Driving a vehicle with rapid oil loss until the engine seizes can cause sudden loss of power, loss of steering assist, and a crash hazard. The problem is ongoing and repeatable, but the dealer refused to diagnose it properly. I am reporting this because the dealership refused to perform required safety‑related diagnostics and instructed me to operate the vehicle until catastrophic engine failure occurs, creating a significant safety hazard for me and other motorists.
