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.
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.
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
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.

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.
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.
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 like myself could’ve burned up in kia death trap. To date they still haven’t made kia responsible for the 1.6 only 2.0 I hope they have a family member experience what I did I betcha they would take care of it then! Kia Corp has denied everything being their faulty piston oil rings that they continue making and using even on their new 2025 cars that are being recalled now! Do I have to die in the car to get recognized and reimbursed for all my out of pocket expenses?? Yep! Kia SUCKS never again!
Car burned out all oil and stalled
Kia is aware of these issues why haven't they issued a recall for engine oil composition low and causing problems
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.
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.
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.
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.
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.
Oil plug fell out while driving, engine needed to be replaced.
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?
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.
Engine knocking noise .
The contact owns a 2018 Kia Soul. The contact stated that the vehicle was experiencing excessive oil consumption. The vehicle was taken to an independent mechanic, where an oil consumption test was performed, and the mechanic determined that the test was positive for excessive oil consumption. Additionally, the vehicle was taken to the dealer, where the oil valve was replaced under an unknown Manufacturer Recall Campaign Number; however, the failure persisted. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the dealer for assistance. The failure mileage was approximately 65,000.
On [XXX], 2024 had a complete break down while driving on the highway on the way home from work. No warning light prior to the incident. 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. Then taken to HW Kia of [XXX] in Ballwin, Mo (this was the closest dealership that said they could get to it right away). Has been there ever since (going on 2 months now). What I have been told has be done by Ian, Service Manager: Compression test done, no compression in cylinder 3. Warranty company (JMNA) sent out inspector. 2 weeks later warranty company asked dealership to do a full breakdown of the engine. On [XXX] got call from Ian that warranty company denied fix under warranty because the damage is to piston rings. (Month and a half just to get this determination from the warranty company) Ian told me that this is a known issue by Kia so he is requested engine replacement directly from Kia Corp. As of today ([XXX], 2024) I am still waiting to hear back if this replacement has been approved. Previously told by Ian (when I initially dropped off the vehicle) that once/if approved it will take approximately 10 days to get a new engine ordered and into the dealership.
