2018 Kia Soul

Engine control system is STILL faulty. The engine light will not go off, even after the so called recall Software fix and the brand new engine put in my car in 2025 among other MULTIPLE brand new parts and repairs to my car trying to resolve the engine issue, oil consumption and fuel/gas consumption at rapid and alarming rate, every time after I fill my gas tank.

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.

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The ABS/traction warning lights came on. On April 29,2026, I took it to Beck and Masten Group 1 Kia inTomball, Texas and they diagnosed as HECU failure. The repair cost $2377.16. KIA corporate denied reimbursement. Lights were resolved after HECU replacement. There was no accident/injury/fire. mileage was 60400. I wanted to note and document as a potential safety trend.

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.

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.

My car was fine one day the next day without warnings was driving on highway and it starting riding sluggish making a rough noise I had pull over to the side of highway turn car off started back up drove home and that was the day my nightmare started. I took my car to the dealership and had a diagnosis performed and they said i need a new engine 8000.00. on 07/25/2024my car was having similar problems the y said it was a knock sensor they fixed that problem. Now I'm02 without transportation. this engine has has a lot of issues. can anybody help with this problem.

My KIA Soul 2018 caught on file while driving. The whole engine was in flames. I didn't want to die because my car has a manufacturing issue that KIA was not aware about. The dealership I've purchased the car from denied to give me a copy of the mechanical inspection done at the dealership Stonebriar Chevrolet in Frisco, TX. The flames started under the car and made its way to the engine, smoke was coming from the AC vents. People were able to put the fire down before it got to the gas tank. Due to the seriousness of the damage, the car stopped working and we left it on the side of the road.

The contact owns a 2018 Kia Soul. The contact stated that while driving at an undisclosed speed, there was an abnormal knocking sound coming from underneath the hood. The check engine and oil warning lights were illuminated. The vehicle was towed to a local dealer, where it was diagnosed with a blown engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. Upon further investigation, the contact related the failure to NHTSA Campaign Number: 20V750000 (Engine); however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 95,000.
