2018 Kia Soul

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.

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.

Unknown...the car goes into limp mode suddenly...my battery was boiling an shot liquid out of it, prior to this my other battery leaked an the alternator was bad ....when this happens suddenly you have no steering, an if course the boiling battery may explode....I've had this car checked over several times since begining of January with everything checking out fine but this still happening

A Kia franchise dealership demanded payment for diagnostics in order to perform a federal airbag safety recall, which I refused. After the dealer’s involvement, the vehicle’s diagnostic/OBD port became unreadable, preventing recall completion. A second Kia dealer states they cannot complete the recall and wants thousands of dollars just to attempt diagnosis. The vehicle has been out of service for over six months with an open safety recall. I believe the recall process has been obstructed.

My engine under, the 2018 KIA Soul Engine Recall, first problem was on October 2023 when it arrived at the dealership with 'no oil'. The mechanic said for KIA to replace the engine. At this time they also found 'sludge' for the first time. I had done my oil changes at the dealership and the most current was August 2023; 2000 miles prior. KIA extended my 100k miles engine warranty to 150k miles. Since, I have experienced excessive oil consumption and firing of the engine. In December 2024, the engine light went on. The KIA mechanic said the engine must be replaced. This time I had a problem finding two maintenance receipts. KIA refused to honor the warranty. The dealership refused to work more on the car. In March 2025, the car began to fire large bangs, then much smoke and the engine seized. What if I was driving on a busy street when this happened? What if the car caught fire? I towed the car to the dealership. KIA manufacturer refuses to honor the engine warranty. I explained to KIA my car has documented engine problems. The sludge found is part of the engine problem. The car uses excessive oil, the high burning is coagulating in the bottom of the engine causing the sludge. I have followed the scheduled maintenance in the owner's manual. I have been harassed, badgered, called names at the KIA dealership who wants me to take my car away. I told all of them I have a car with a well known and documented engine defect that they must fix. I read the NHTSA 23V-099 recall. My KIA Soul has experienced similar problems according to the descriptions from the KIA mechanic. Because my car does not fall within the specific car description KIA keeps turning me away. I am driving an unreliable and unsafe car on the road. We cannot allow KIA to continue to sell unsafe cars they have no intention to correct. Another problem that began after the October 2023 break is the car has an error that reads, '...the battery is on'. I have replaced 3 Die Hard batteries since. Thank you.

The contact owns a 2018 Kia Soul. The contact stated that the engine was consuming an excessive amount of engine oil. The contact had to add one quart of oil per week. The battery was replaced on three occasions. The contact stated that the vehicle failed to exceed 57 MPH while driving. There was an abnormal creaking sound coming from the vehicle. The contact also stated that there was no oil in the oil pan, but there was no indication of a leak. The oil light was illuminated. The contact stated that the engine was limp, and the starter was becoming inoperable. The vehicle was taken to the local dealer, where it was diagnosed that the engine was becoming inoperable, and an engine replacement was recommended. The vehicle was not repaired. The vehicle was taken to another local dealer, Kia of Naples (3325 Westview Dr, Naples, FL 34104) for an oil consumption and rod bearing test. The manufacturer was contacted and extended the warranty to 150,000 and declined to replace the engine due to missing maintenance records. The failure mileage was approximately 70,000.

My vehicle recall is to do with electrical issue that not only may have affected the air bag, but the electrical system shorting that’s burning the bulb holders that holds all of the brake and tail lights bulbs on this vehicle. These brand new bulbs consistently burn or short out within 1 to 2 weeks. This expense has grown expeditiously over the years of ownership, and because there is nothing in the information center to warn us, we are constantly due to no fault of our own, unknowingly driving with no brake light. Having to drive regularly on interstate 4, with traffic stopping warning, this is a great safety concern. Brake light are very very essential driving in sudden stopping traffic. Kia should be liable and responsible for correcting this traffic hazard. Thank you notes.

The contact’s daughter owned a 2018 Kia Soul. The contact stated while her daughter was driving approximately 65 MPH, another driver honked the horn to inform the driver of an issue with the vehicle. The contact was informed to pull over. The contact stated that the vehicle started jerking and the driver started seeing smoke coming from the engine compartment. The contact stated that her daughter’s hair was singed by the fire. Several unknown warning lights were illuminated once the driver saw smoke coming from the vehicle. The driver pulled over off the highway and exited the vehicle and saw smoke coming from under the vehicle before the vehicle became engulfed in flames. The contact stated that the vehicle had previously been serviced and there were no issues found with the vehicle. The fire was extinguished by the Fire Department. The contact was unsure whether a Fire report or a Police report was filed. There were no injuries sustained. The vehicle was towed from the scene and was deemed totaled. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 63,000.
