2018 KIA SOUL Engine Problems

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

Excessive oil consumption

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.

Description of the Problem: My 2018 Kia Soul has a recurring and unresolved safety issue involving sudden loss of power while driving. The check-engine light repeatedly comes on, and at times the vehicle will hesitate or lose acceleration unexpectedly, creating a risk of being unable to maintain speed in traffic. Chronology: This issue has been occurring for over a year. I have taken the vehicle to the Kia dealership multiple times for the same problem. Each time, the dealership has either been unable to diagnose the cause or has returned the vehicle stating the issue was repaired, but the problem returns within weeks. Most recently, the dealership kept the vehicle for over a month and still could not identify or resolve the cause of the power loss or the recurring check-engine light. They then instructed me to pick up the car and drive it until the warning light comes back...

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...

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

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...

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.

Going through oil so fast excessive oil use

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.

Check engine light flashing and began to lose exceleration. Pulled off the highway and vehicle died. Unable to start it. Told that the engine is bad by a mechanic.

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.

Nov 10,2024 my 2018 Kia soul “1.6” (1.6 is important because only the 2018 Kia soul 2.0 got recognized in class action lawsuit for exact reason my 1.6 did engine fire but yet YOU nor KIA will take responsibility for the fire and you guys for not doing a recall on it) biggest problem I have is when I purchased it from kia lot in Carlsbad ca the salesman NEVER mentioned one word they’re known for catching fire nor mentioned someone actually died in car from engine fire to me that’s crappy customer care all the way around and Kia DOES NOT GIVE A CRAP ABOUT THEIR CUSTOMERS WHAT So EVER!! Was driving down fwy going to work and smoke coming from my engine my engine was on fire. Aug 2024 I had oil change and tuneup just months before the engine fire. NHTSA doesn’t care either how many people...

Car burned out all oil and stalled

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...

The vehicle has been well maintained. About 1.5 years ago, it experienced a fuel injector failure. All four injectors were replaced to ensure the health of the engine. Recently, while on an 8-hour trip, halfway through, the engine experienced a sudden loss of power on the highway, nearly resulting in a crash, and the check engine light illuminated. The car was towed to a Kia dealership, where they stated the engine had failed. Cylinders 3 and 4 have ring and valve damage. The car had been performing well with no issues or warning signs, such as a trouble light or high temperatures. All other diagnostics were rated green by Kia.

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...

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....

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.

Oil plug fell out while driving, engine needed to be replaced.

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...

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...

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...

Towed via ERS on my auto insurance policy to Plaza Tire Service, [XXX] . They replaced spark plugs and coils. Still sputtering and code on cylinder 3.

While driving vehicle, engine reduced power and went into a limp mode, pulled off Highway and stop. Check engine light came on and blinking. Later found motor had lost over three quarts of oil. Now engine knock and have been advised by mechanic that engine is about to throw a rod thru the the side. Vehicle has had oil changes at 5000 miles intervals thru out its 124,000 miles on the road also oil checks often too. Now we are without a vehicle with a damage engine. I understand thru research that this is a common problem for this type vehicle and motor.

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

Second time in last six months car went into “limp mode” with the knock sensor. First time it was “just” a faulty knock sensor and under warranty. Happens again now it’s the all too well known the oil is burning too fast on this engine. Kia/hyundai will not take this under warranty as it is not a rod bearing issue while numerous owners have the exact same issue. This cars engine can probably fail at any time with this oil issue continually happening. The cars oil has been maintained per manual and was not expecting an oil change yet the level is way too low already (3000ish which is way before the 5000 mile mark per owners manual and Kia)

2018 Kia Soul with excessive oil consumption. 1.6 Liter GDI engine. Base model. Oil is being overly consumed in between oil changes, needing double the quarts in between Kia's manufacturing guidelines.

The engine is burning a TON of oil and I have to put 5 quarts in every 2-3 months. I also found oil when I pulled the 2nd and 3rd spark plugs (from left to right). I checked the engine again and it’s bone dry.

I took my 2018 Kia soul into the Kia dealer for a couple recalls, one of them was that KSDS (knock sensor detection system) shortly after that, my engine light started going on. I took it back to the Kia dealer and they change the oil And charged me for it. My engine is burning oil and it's having to be replaced by a quart every couple weeks. I pulled into Valvoline the other day and explained what happened and the young man called his supervisor and came back to me and said they cannot change the oil because , my car engine is at fault and could start a fire or blow a rod. I've been in touch with my Kia dealer and they tell me that my extended warranty is not valid however, when I look at the proposed class settlement soon for engine issues, such as engine,...

Car Insurence informed us that the Car is Missing the engine anti-theft interlock system and no Dealership is not responding, I have COPD and can not have the car missing for a TicToK steal this car challenge by Hyundai/KIA.

My 2018 Kia Soul is guzzling oil even after an oil consumption test and a head gasket and valve cover gasket replacement. We are using a quart of synthetic blend oil every 500 miles. We cannot be the only people with this complaint!! Vehicle has less than 95,000 miles on it. The Kia Dealership in Clarksville, TN has been the only place to work on our vehicle since buying it a little over one year ago. Said vehicle has been guzzling oil since day one of our purchase.

My engine failed on the I-74 due to excessive oil usage that the original owner reported to Cronin Kia at 38,911 miles.The engine was never repaired and instead 6 miles later with me unaware of it having engine problems I was buying this car for my daughter to which after multiple complaints about it using oil and opening up claims it finally blew up.Now they say it is out of warranty. How does a car company get away with this?
