The engine has been consuming oil. When I brought it to the attention of the dealership the recommendation was to oil consumption test and also to clean the combustion chamber. On this car they lost a class action lawsuit for these engines consuming oil. They are using their faulty manufacturing processes to get more money out of consumers. The only way they said they would approve an engine replacement is to have the engine seize up while driving. This is unsafe for the driver and also for the other motorists. This would put the driver and other motorists at risk because the car can become uncontrollable and could cause an accident. The car has been inspected by a dealer multiple times and they said they would not replace it until the engine seizes. Also Kia corporate said the same thing even though they lost a class action lawsuit. The warning lights come on when the oil is low. Also check engine lights have been coming on for the oil issue. Kia should be replacing these faulty engines and the consumer should not have to pay for tests to be able to get the engine replaced that is under warranty.

My 2018 Kia Sportage (VIN: [XXX] ) triggered a check engine light and entered limp mode. Diagnostic scan revealed DTC code P1326, which is associated with the Knock Sensor Detection System (KSDS) and often linked to engine bearing failure in many affected Kia models. This happened at approximately 120,000 miles while driving under normal conditions. The car now runs in reduced power mode, making it unsafe for highway use or commuting. I contacted my local dealership, who confirmed no recall or campaign was active, despite this being a widely known and reported safety defect in Kia’s 2.4L GDI engines. I am requesting NHTSA to investigate this issue further, as many Kia and Hyundai vehicles with this engine have experienced sudden failures due to this defect. Kia should extend warranty support or issue a recall to prevent dangerous engine shutdowns. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Excessive oil consumption and the engine is part of a "silent" recall. I would like my engine to be replaced before it blows up and causes serious injury or death. I do regular oil changes and I can't keep adding oil daily. If they knew about this issue why wasn't there a mass recall to get this fixed.

I was riding on the highway at about 65 mph and then the check engine light came on, the car slowed down and lost power. Now when I take off I have to barely mash the gas to pick up speed, if I mash the gas pedal hard it barely moves and it loses speed and power going up a hill. I took the car to two different part store and had a reader hooked up and it said the power powertrain control module needs a reprogramming.

My check engine light has been on for some time . It will go off for a day and a half and then come back on . I was told by one garage that it was the catalytic converter. I have 99,339 miles on . It was tuned up and the light had gone off until the next day . Runs good and body is in great shape . I’m disappointed with this since it’s not covered ! And my lights are not working , the garage said it was a bad connection .

I had an oil change done because my engine oil level was showing low on the dipstick. I had just had an oil change about 2 months prior so it was not due but I thought that maybe there was an oil leak . On the way to my mechanic shop the check engine light came on so I had them to check it out. There were no visible oil leaks and they said they oil was extremely low. They did the full oil change and told me to bring it back 200 miles later to see if there was any oil lost. 200 miles later the car was down an entire quart of oil. My mechanic suggested I call Kia to advise them of the engine oil consumption issue. His words. I called Kia and was advised to bring it into the dealership for a diagnostic and consumption test. I am bringing it tomorrow morning but I don't know what will happen after that. I see the recall for other models with this same issue but not for my model.

I just found out by the jiffy lube manager where I go for my oil changes. That my Kia is involved in the oil consumption leak. I purchased it used and still making payments on the car. I have tried working this out with Kia and the dealership with no support or assistance in this matter, So frustrating when they know it’s an on going problem with their vehicles and the oil consumption leak. Really need help with this. I had two warranty on the car and the oil consumption leak is excluded from both. How convenient.

I am writing regarding the KIA recall #SC336. About 6 months ago I noticed my 2018 KIA Sportage w 139,000 started using a lil oil. Then 3 days ago it starting cutting out & ck engine light came on. I called mechanic & took it into his shop. He put a coder reader on it and it said, misfire on #2. He did a compression test and there was 0 pressure on #2 cylinder. He then took a camera and went down and there is a hole in #2 piston. He recommends a new engine. He had me call the KIA Customer Care # however, they basically told me the deadline for class action suit expired and I had no remedy with them. My car was not acting up at the end of said deadline so, why would I have filed a claim?! I seen this info on recall #SC336 as to oil consumption & no compression in '20-'23 Souls and Seltos. I have also seen several mechanics forums speaking about my year of Sportage with compression issues. I am a poor lady on disability and still owe $11,000 on this car w no extended warranty coverage. Is there anything I can do in order to get KIA to include my vehicle in an engine recall ? I have now obtained a loan for the $4,800 rebuilt engine I just purchased from Auto Zone! Thank you in advance for your attention to this matter.

Mar 3, 2025Electrical system

Driver power window regulator stopped working. It is available for inspection upon request. My safety is at risk because it can hinder my ability to exit the car in an emergency. In addition, it is exposing the car's interior and possibly interior electrical parts to the weather elements, and potentially leaving me vulnerable to theft or intrusion. The problem was intermittent at first, and I reported it to the dealer, but at that time of service, they were unable to reproduce the failure. The service department told me this is a fairly common problem with my model of car. The component has not been inspected by Kia, the police, insurance representatives, or others. The symptoms were intermittent at first prior to the total failure. The full failure happened at 101,500 miles, which is past the 100,000 mile warranty expiration.

Sudden strong hot fire smell out of nowhere. Immediately looked at my C to H gauge. It was not on C yet not all the way on H. I immediately looked for smoke/fire from vehicles in front of me as I have seen semis and diesel trucks appear or actually on fire while traveling. No more than Iook I up and look back down at the gauge which was now over halfway now closer to H, smell was stronger and smoke seen seeping through my instrument dashboard and honestly I was having a brief moment where it didn't seem real (between military trauma and fear of burning up in a vehicle). I was right at a stoplight so very quickly smoke started to engulf my engine hood coming out of all sides and I felt it was about to explode as quick as the smell and clouds appeared. I took an immediate left turn and quickly pulled into the parking lot near and immediately got out and called 911. Someone seen it up in smoke and told me he thought it smelled like a fire. I informed him 911 was coming. Two fire engines showed up along with EMS & police along with about 3 non fire engine volunteers. As I turned the vehicle off immediately prior to 911, the smoke started to subside outside of the vehicle. A firefighter in charge informed it was a fire risk/hazard, do not turn on and to contact KIA right way to report...have towed. I have been informed there was huge amounts of oil loss at one time, engine leak concern involving an oil feed tube. I was informed by dealership that so much oil spilling out that a fire could have started if it did not. Firefighters showed sprayed oil to the back of the vehicle under hood that should not ever be there and recommended to not drive.

I lost power and was sandwiched between semis and as I was going over one of the mountains, I went from 70 mph which was the speed limit at the time down to 45 to 50 I mean I couldn’t keep the speed. It was sudden with no warning and also had this happen on previous occasions which was reported to KIA. It caused road rage from drivers and also almost multiple accidents over time. I thought at one point I was going over the side of the mountain that didn't have guard rails due to sudden slow down and no where to go and semi behind me. Ended up with a new Waste Gate.

first time I had an issue was in August 2023, my check engine light came on, the car was losing power and sputtering. when I would start the car, it would literally sound like a truck. come to find out, the 3rd cylinder was misfiring due to the piston rings being worn and possibly the coils being faulty and an engine replacement was needed. after going back and forth with the dealer (they had my car for almost a month) the engine was finally replaced. fast forward to last week, it started happening again. same cylinder, same issue. now my car is back in the shop waiting for a new engine (#2). my thing is this....did they use a rebuilt engine, or maybe just fixed the old one and call it new. either way, there is no reason I should need a new engine this close to having it repaired. and judging by the complaints I have been reading, the engines on all 2018 Sportages need to be recalled.

The contact owned a 2018 Kia Sportage. The contact stated that while driving at an undisclosed speed, he observed black smoke billowing from the engine compartment, after which the vehicle lost motive power, prompting him and his wife to evacuate the vehicle in the middle of the roadway. While attempting to retrieve important belongings from the vehicle, the contact stated that he heard what sounded to be an explosion within the engine compartment, causing him to fall backward and sprain his ankle. Moments later the front end of the vehicle was completely engulfed in flames. Local emergency services arrived and were able to extinguish the fire. The vehicle was towed to a tow yard and needed a total loss by the contact insurance provider. A fire report was filed. A police report was filed, but no injuries were reported. The contact later transported himself to an appointment with his primary care physician after experiencing physiological symptoms consistent with a cardiovascular event and was treated for angina. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 21V137000 (Service Brakes, Hydraulic); the VIN was included, but the vehicle had not been repaired. The manufacturer was notified of the failure, and a case was opened. The contact was informed that the manufacturer intended to inspect the vehicle but stated that the inspection had yet to take place. The failure mileage was 55,000.

Connecting rod bearing failure on 2018 Kia Sportage two months after having been to the Kia dealership for a knock sensor software update. (sensor update completed on 7/26/24 at Palm Springs Kia, RO# 6160694/1, engine failure occurred 9/23/24.) Upon doing research, I discovered that connecting rod bearing failure has been a recurrent issue over the years with Kia engines. I believe that my engine is also victim to this defect.

Code P0303. Took car to dealer for diagnosis, dealer recommended long engine block replacement due to bad pistons. Kia will not replace. Car has 68K miles on it. Called Kia and they will not even do a goodwill replacement. There is a history of engine failures on my same year and model car but not for this exact reason.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2018 Kia Sportage Plug-in Hybrid verdict →
