2018 Kia Soul Engine Problems

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.

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.

Was going down the freeway the check engine light came on pulled over and found there to be no oil on the dip stick and I had just checked it a week ago. Now the engine is knocking due to the oil consumption.

Excessive oil consumption

The engine seized up at 165,000 miles. According to one [XXX] at Trinity Automotive in Fairfield, Ohio, it's a known issue. According to [XXX] at PrebCo in Eaton, Ohio, the issue is related to low-pressure piston rings. Compression tests showed between 0 psi in one cylinder and between 55 and 58 psi in the other three cylinders. These issues have been verified at Matt Castrucci Service Center. With a GDI engine, I had been chasing down the usage of too much oil for several months. I get oil changes at 3,000 miles, and I would be 1/2 quart to 1 quart low at 3,000 miles. Dealership service staff in Beavercreek, Ohio, said that Kia considers the usage of one additional quart of oil per 1,000 miles to be "acceptable" - that makes zero sense. I was told that they would do a piston soak, and they directed me to a formal procedure on Kia's website. I used this process, and it definitely cleaned out all of the carbon. This did not fix the issue. Taking my youngest daughter to a dinner following her high school national honors society induction, I experienced an engine knock as I accelerated onto the I75 north. It felt like a strong jolt back. The 2018 Kia Soul Plus has been a 3,100-pound roadside decoration since November 2025. I still owe 14,000 on this loan, and I cannot afford an additional car payment. Replacement of the engine will be 8,500. Kia customer service told me this is an out-of-pocket expense as their warranty ended at 150,000 miles.

Kia is aware of these issues why haven't they issued a recall for engine oil composition low and causing problems

Engine is loosing oil into the #2 cylinder, causing an damage to the downstream exhaust. Once the cylinder fills with oil, the care immediately drops in operation speed causing significant driver response and immediately surrounding vehicles

Low compression on cylinder 3 and 4 and the car only has 40,000 miles on it. It's not covered in warranty because it's a 2018 model but I've only had the car for 1.5 years and still owe 18,000 on it and I'm a officer and a single mother and can't afford to let the car go back when Kia knows these cars have engine issues and low compression engine problems.

9/25/25 Car would not accelerate on exit ramp and engine seized just as I pulled into Romeo Kia Kingston Car Repair Center, causing a dangerous driving situation. No prior noise or warning lights for the 6 years I have owned the car. 10/6/25 per Jared Illg, District Kia Mgr., “Although, my 2018 Kia Soul 2.0 engine is under the Class Action Settlement, my car is not under extended warranty, because I did not have the KSDS software update.” I did not receive any mailings over the years, but two August, 2025 re-notifications. •Kia KSDS software 2018 update (172/953), why wasn't update performed by Romeo Auto Group Dealership before I purchased car? •Kia’s parent company, Hyundai Motor Group removed the KSDS update requirement for its lifetime engine warranty, why hasn’t Kia? •The Romeo Auto Group Dealership owned this car and used it as a Lease Car. I am second owner, why didn't I get a Transferable / Powertrain warranty? •Why would I get a limited warranty knowing the Kia Soul has faulty 2.0 engines since 2012, defects that arise in the car that originate from the factory; resulting in numerous lawsuits and class action settlements. This is not a case of owner neglect; I have taken excellent care of my 2018 Kia Soul. •I did not receive TSB-19 and TSB 222 which refers to known defects of all these connected components: excessive oil consumption, defective piston rings, and rod bearing failure; resulting in catastrophic engine failure. My mechanic has installed a used 53,000 mi. used engine. I now have a debt of $8,817.91 for a 2018 Kia Soul I have owned for six (6) years. I am so stressed this has a disastrous impact on my financial situation. Desired resolution: I am asking for Kia America, Inc. to reimburse me my expenses of $8,817.91 (replacement engine, towing, and car rentals; attached) and provide the extended Warranty for 150,000 mi.

Out of no where my engine just started knocking. No engine light came on, no oil light came on, no warnings at all. I just got an oil change 12/18/2024, with 2 top offs 04/23/25 and 07/23/25. And August 24 th my engine started knocking. I took it to Midtown kia on 08/25/25 and they told me Kia customer care won't cover the engine recall.

The contact owns a 2018 Kia Soul. The contact stated that while driving at an undisclosed speed, the vehicle inadvertently lost motive power. The contact was able to pull over to the shoulder of the roadway, where the vehicle failed to restart. No warning lights were illuminated. The vehicle was towed to an independent mechanic, who diagnosed a failure with the piston oil rings, resulting in damage to the engine. The contact was informed that a piston was missing and that the engine needed to be replaced. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 25V099000 (Engine and Engine Cooling); but the VIN was not included. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 130,000.

ENGINE SHUT OFF WHILE DRIVING IT DOWN THE HIGHWAY Purchased 8/5 from reseller, who had driver it over 200 miles with no issues. Had it inspected that day and no issues found. Scheduled appt w/ Clay Cooley Kia to drop off 8/12 to have warranty recalls addressed. Clay Cooley inspected and found no issues, verified in good shape; work completed 8/14. On 8/18, after driving it less than 183 miles, the vehicle COMPLETELY SHUT DOWN on the highway. The check engine light came on immediately before the car shut down, but that was all. It was incredibly dangerous. Searched online and discovered that this has been a know issue with Kia Souls. Discovered online that this was a known issue, and had previously been the focus of a class action lawsuit. Contacted Kia corporate who mandated I take it back to Clay Cooley Kia. Clay Cooley Kia refused to repair it, and Kia Corporate refused to handle further.

On 8/12/25, my 2018 Kia Soul (approx. 126,000 miles) suddenly began shuddering at low RPM with a flashing check engine light, near-stalling, and smoke from the exhaust. A warning message appeared for an engine control issue. Prior to failure, the engine intermittently knocked and displayed an oil pressure warning light. The engine burned oil at an excessive rate between routine oil changes. At the Kia dealership, diagnostic codes P0300 and P0303 were found. The dealer reported a burnt valve and seized starter, estimating $2,960 for valve repair or $6,437 for engine replacement, and stated these were not covered under Kia’s extended warranty or E2 Class Action Settlement because no P1326 code appeared. However, the symptoms match the rod bearing wear defect already covered under the E2 settlement. The dealer refused to perform the bearing clearance test (Kia’s required diagnostic for this defect) without payment, even though the settlement and extended warranty specify Kia must cover all inspection, diagnostic, and repair costs for potential rod bearing failures within the 15-year/150,000-mile coverage period. The engine failure created a serious safety risk when the vehicle lost power and nearly stalled in traffic. The burnt valve and seized starter are likely secondary effects of bearing-related long block failure. Kia’s refusal to inspect the vehicle without charge contradicts the settlement’s intent and prevents proper diagnosis of a known defect. I request that NHTSA investigate Kia’s handling of inspection and warranty coverage for vehicles showing these symptoms but lacking code P1326.

I have owned this car now, for 3 years and uh, in those 3 years, I have had to add a quart of oil to it every week. There is a problem with oil consumption. It does not burn it and it does not leak it. And uh, apparently, kia says there is no problem. So in my opinion, the 1.6 l Kia engine is garbage. It has blow by if I take the oil cap off. The oil cap will sit there and rattle and blow off. Now it sou ds like it is getting ready to blow the motor, it has a rod knocking.

Car burned out all oil and stalled

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.
