Engine, Apr 9, 2025, fire
The contact owned a 2018 Kia Soul. The contact stated that while driving at an undisclosed speed, a loud pop and smoke emanated from the engine compartment, prompting her to pull to the shoulder of the roadway. After a visual inspection, the contact observed flame jutting up from the engine. The contact was able to extinguish the fire herself using a gallon of water she had on hand. No warning lights were illuminated. A fire report was filed. A police report was not filed, and no injuries were reported. The vehicle was towed to an independent mechanic, who diagnosed a nondescript failure with the engine. The vehicle was not repaired. After investigating the failure, the contact related the failure to an NHTSA Campaign but was unaware of the NHTSA Campaign Number. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 125,000.

While climbing a hill, the engine began to sputter and lose power immediately, throwing multiple CEL codes. I was barely able to get it off the side of the road and shut the engine off. We were very lucky to be driving at a time when the road was not as busy as usual and experienced no collisions, though we were stranded on the side of a road with no cellular service for 2 hours before we could get towed. A mechanic reviewed the engine and suggested the piston rings blew and there was oil leaking from the exhaust manifold. Smoke was pouring from the rear of the engine, likely from it burning through the exhaust manifold, and the back of the engine was covered in oil and dripping out what oil was left in the engine at a rapid pace on the side of the road. This aligns with known issues for these engines involving oil consumption at unreasonable rates and the class action settlement for rod knock issues. The vehicle is able to be inspected. I am not comfortable starting the car as it continues to make horrible noises. The CEL codes produced were multiple misfires and individual cylinder misfires, P0300, P0301, P0302, P0303. The CEL illuminated after the engine lost power and made the noises, flashing repeatedly along with the oil indicator light. The oil light had not illuminated at all prior to indicate an issue with oil levels or pressure. Oil was present in the vehicle at acceptable levels approximately 95 minutes or 100 miles prior to the failure. Only the mechanic hired has looked at the engine so far.

The camshaft bolt broke off and destroyed the engine. A second bolt worked itself loose and photos show it at least half way out. Less than 100k on vehicle. The car was on the freeway when it lost acceleration ability. The dealership requested the extended warranty cover the replacement of the engine and they denied coverage. A few months before the codes for camshaft sensor came on. We replace the sensor and the car worked fine until recently.

My 2018 Kia Soul burns oil creating the engine to misfire, stall, putter, tick. Ive had my oil changed on a Friday, and by Tuesday, there is no oil left in my engine. The local Kia dealership is currently doing an "oil consumption" test, however was alerted by Kia Corporate to not go any further unless I get them 7 years of my oil change records. My car is still under warranty. I have provided the oil change records. The local KIA dealership advised I drive my car if I need to, knowing there is a faulty engine, and that could cause harm or death! KIA does NOT stand by their warranty and tries to nickel and dime their good, loyal customers. They manufacture faulty engines, putting peoples lives at risk! My car is sitting at the dealership, waiting on approval from KIA while I am left with no car. Also, the dealer does not have any loaners available.

While driving on the interstate @70mph with the cruise control activated and set the engine started without any warning to slow down. at this time the engine was sputtering, and the check engine light came on and we were unable to keep the car at speed. 12The vehicle was then driven about a mile to a KIA dealership. We were then told the engine had a multiple engine misfire and they would want the car for about 3 weeks to determine what happened. We then had the car towed to another mechanic who in a couple of days told us that there was no compression in cylinder #4 and the engine was blown.

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.

Electrical system, Exterior lighting, Service brakes, Sep 2, 2024
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.

While driving the vehicle, with no warning, the engine failed. The second cylinder lost all pressure, with the remaining 3 cylinders at the lowest passable pressure. This was on the highway, and the car began jerking and shaking, not allowing to follow flow of traffic. There is supposedly a recall for this issue, however Kia is refusing to cover the car, as it has 120,000 miles and is past the power train warranty. Kia dealership told me it was covered, while Kia is stating it is not. So now I have a 6 year old, $30,000 lawn ornament.

I have a 2018 Kia Soul Base Model with a 1.6 L engine. At the moment, the engine is making a loud knocking noise when the car is running. Also, upon checking the vvt solenoid there were metal shavings as well, which is a common symptom of engine failure. The safety of mine as well as other drivers are at risk as the engine can stop automatically while driving without any warning. The problem has not yet been reproduced or confirmed by a dealer and has not been inspected by others. There are no warning lamps or messages besides the loud knocking noise and metal shavings found.

I am the owner of a 2018 Kia Soul. On May 19, 2024 I broke down on a highway in a dangerous construction zone. Just prior to this my oil light came on, so i put some in to be safe until I got home to let engine cool. No other warning lights or messages came on. Got a little further down the road and the light came back on with the engine now making noise. I managed to find an emergency pull off and as soon as I pulled off the car died. I had it initially towed to my mechanic but when they looked at it they said had to go to dealership it was the Engine and possibly under recall. Had towed to dealership on May 21, 2024. They were backed up and unable to look at it until after the holiday. They finally got to look at it on June 3, 2024. It does meet the requirements for the Kia Engine Recall. Here is where the plot thickens, Kia, not dealership, denied the recall work because the update was never done. I just received the update notice the end of March 2024. Due to me being disabled and I had some doctor appoints to keep I just cleared my schedule to make the appointment and was planning to do that when broke down with no warning. I called Kia customer service and they said because I did not have the update done it has to fall under the Class Action Settlement and they will not cover it. Now under the Class Action Settlement, you need to pay out of pocket and then seek reimbursement. However, the work has yet to be done and I am disabled and on a fixed income. It is now June 10,2024 and the Kia dealership still is not getting a straight answer from the warranty company on whether they will accept the claim and cover it or not. Meanwhile, I am putting a friend out to help me. What is a person to do?

Update to case 11587168: Ian (Service Writer) at HW Kia told me 3 weeks ago Kia was approving engine replacement, he was ordering the engine & to provide all service records so they have them on file. I provided receipts for 2 oil changes I had done by a non-Kia dealership auto service. All other service records are accessable via KIA & CarFax as Napleton Kia St. Peters & Plaza Tire Service had done all other oil changes/ maintainence on the vehicle. The Thursday before Memorial Day I get an email from Ian that now Kia is denying the engine replacement. I am now waiting to get a contact from the RPSM (Regional Parts & Service Manager) as to why since I provided proof the vehicle was properly maintained. This is a wrongful denial in my opinion.

My granddaughter was traveling to Florida from Texas for a short vacation on [XXX] 2024. Car just lost power and slowed in the middle of the interstate traffic, no lights, warnings or anything. Thank God she was able to get to the side of the highway without getting hit. It was knocking and clattering in the engine. Killed it and let it rest a bit and checked the oil and it was [very low, added some oil and started it back up, but it still was knocking and not running. Had it towed to an independent garage in Crestview Fl. The mechanic diagnosed the engine with a possible bent valve and loose timing chain. The car has 104000 miles on it. We had the oil changed at 102000 and have had oil changed regularly at 5000 miles or less since we bought it in March 2022. We still owe a loan on this car. Mechanic said the engine would have to be replaced and quoted 7000.00. We cannot afford this. We are the 3rd owner and was not informed of any safety recalls or software updates until the Mechanic told us about the Class Action Lawsuit and the issues with the engines in Kia and Hyundai. Kia is not forthcoming with this information and does not notify but only the 1st owner. This is ridiculous and not right to do the consumers this way. We bought the car from a Nissan dealership in Mckinney Tx and was not told anything about this. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
