2018 Kia Soul

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.

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 submitting this complaint regarding failure to complete a federally mandated safety recall and the subsequent release of my vehicle in an unsafe condition after prolonged dealer custody. Vehicle Information provided above Safety Recall Information Recall Type: Federal airbag safety recall Recall Notice Received: 2023 Summary of Safety Concern I delivered my vehicle to authorized Kia dealerships for completion of a federally mandated airbag safety recall. The vehicle remained in dealership custody for approximately seven months without completion of the recall. During this period, the dealerships demanded payment for diagnostics and asserted that recall-related issues were “warranty-related” or “customer responsibility,” which effectively blocked completion of the safety recall. Despite my continued communication and willingness to proceed with recall repair, the recall was not completed. Kia declined to authorize repairs necessary to complete the recall. Vehicle Released Unrepaired and Unsafe The dealership ultimately demanded that I remove the vehicle without completing the safety recall. Upon retrieval of the vehicle, I discovered: Missing and/or altered vehicle components Extensive interior water damage These conditions were not present when the vehicle was delivered and occurred while the vehicle was in the dealership’s exclusive custody. The vehicle was released in a materially worse and potentially unsafe condition. Ongoing Safety Risk The federal safety recall remains unresolved. Electrical systems and safety components may be compromised. The vehicle is currently unsafe to operate, and repair is no longer a reasonable remedy. Basis for NHTSA Review This complaint concerns: Obstruction and noncompletion of a federal safety recall Improper conditioning of recall repairs on payment Release of a recalled vehicle without repair Potential compromise of safety systems while in dealer custody

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.

We purchased this vehicle for our [XXX]. It was going to be his first vehicle, and we shined it up and changed the battery, detailed it, changed all spark plugs, the whole nine yards…so on his [XXX] we give it to him, and we take it for a test drive, and the engine seizes up and we have to tow it to our mechanic. He assesses the car, and its rod bearing wear that is under a class action lawsuit. After calling Kia, they will not do anything about it because it has never had a specific software update that is under a product improvement action. A knock sensor detection that would detect prior to engine failure. I told Kia that we looked up recalls on the vehicle and there was nothing regarding that on the search. From both their website, and NHTSA. And they said that it wasn’t their responsibility to do so. But it was their failed product and design, that put my child at risk, and we had no reasonable way of knowing about it. They said it wasn’t their responsibility. I don’t understand how a detection system of the engine failure, would be required after the failure? There’s no prevention aspect to the “product improvement”. At this point, it serves no purpose, the engine failed for that reason. And installing the software update prior to failure wouldn’t have changed anything. They have orchestrated a loophole to not be accountable for a design and product they out on the public market, which they received financial compensation for, that could have cost my child’s life. In fact, they won’t even pay to replace the deficient engine that broke because of their negligence in design and risk assessment. They are 100% unwilling to address the defective product they sold.
