2018 Kia Soul Electrical Problems

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.

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.

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.

Car stalled in the middle of the road while driving. Took it in to dealer ship for a recall to get this repaired or flashed. Engine burning excessive oil. Car has always been kept up with maintenance. While operating the vehicle the car stalled due to low oil compression. Vehicle has aprox 155k miles. Check engine light has came on. Due to the issue that car engine is burning oil there is a new permanent code p0420 which is a bad catalyc converter since the cars emission system is failing. Car has been sitting at home for about 1 month or longer as we don’t drive it and are still financing the vehicle

My Goddaughter has had random starting problems with the 2018 Kia Soul plus, that I bought her. If you turn the key you hear a click but it won't start until you try several times. She has had to get a jump on occasions. We bought a new battery, thinking that was the problem, but that didn't solve the issue. Taken car to the dealership several times, but they say that they can't find a problem. She get nervous everytime she goes somewhere and cut the car off, thinking she's gonna get stranded. I'm afraid for her, getting out there at night time that car not starting for her. Researching this issue online, I found out that this is an issue that numerous people have complained about, an addressed the issue as well. This is a safety issue that needs to be addressed by Kia. Thinking about trading her Kia Soul, and buying her something more reliable.

Buyer beware, DO NOT PURCHASE A KIA. Kept up with oil changes on the car. Purchased used in 2019 at 45k miles. While driving from work car just stopped working, and engine and oil light turned on. Electrical was working replaced battery maybe two months earlier. Wasn’t due for an oil change. Took car to a mechanic who said it was low on oil which seemed odd. Also replaced brake pads and rotors. $1000 later the car starts making a horrible rattling sound and the oil light and engine light turn on and car almost immediately dies. Took car to dealership, engine is done. This is happening to ALL of Kias cars that are being put on to the market. These cars are STILL being sold and they are all very much aware that these engines are bad. An entire decade of BAD ENGINES from Kia. And they are doing nothing. NOTHING. No recalls on this car. So now I am f*****. I have had this car for TWO years and it is only THREE years old and the engine is DONE. How is nothing being done about this???? Why are our voices being ignored?? There are complaints on this page with this EXACT issue. Why aren’t these cars being recalled?? I had my boyfriend and 3 dogs in the car, what if my car had caught on fire like their other crappy cars they have put out? Would I just be another person murdered by Kia and no one does a thing about it? (Allegedly)
