2017 Kia Sportage: excessive oil consumption

Filed Jul 6, 2026 · Engine, Fuel system · MN

After fueling, vehicle idled fine with no warning lights. Once pulling onto the highway and making highway speeds, the vehicle suddenly lost acceleration, and was stranded in the highway. We required the assistance of law enforcement to direct traffic. It was 10pm and the temperatures were 35 degree below zero with the windchill. The vehicle was towed to a Kia dealership, where they diagnosed loss of compression in the pistons. The dealership stated the engine had been burning/consuming oil and that the burnt valve caused the loss of compression and sudden breakdown. This vehicle uses the 2.4L Theta II GDI engine, which has a long history of engine failures, oil consumption complaints, stalling, and class-action litigation involving sudden engine failure and loss of power. Kia denied coverage by claiming only rod-bearing failures qualify for warranty extension, even though excessive oil consumption and compression loss appear closely related to the same broader engine defect pattern. Other owners have also reported 2017 Sportage excessive oil consumption leading to compression loss and engine failure. I believe this is a serious safety defect because the engine can fail suddenly while driving at highway speed, drivers may have little warning before loss of power, oil consumption may not trigger adequate warning before catastrophic failure. This creates crash risk, roadside hazard exposure, and potential fire risk.

My 2017 Kia Sportage has experienced excessive oil consumption, cylinder #3 misfires, loss of power, and highway stalling events. The dealership initially documented engine damage and indicated findings consistent with internal engine failure, including concerns related to metal contamination and cylinder damage. These issues appear consistent with numerous complaints from other Kia owners involving the same engine family. Kia has since backtracked on prior findings, and both Kia and the dealership have stopped responding to my requests for clarification and documentation. The cylinder damage and related engine failures appear to be symptoms of a larger engine defect that poses a safety risk due to sudden loss of power and stalling while driving. I request that the federal safety agency investigate these recurring engine failures and Kia’s handling of these claims.

What component or system failed or malfunctioned, and is it available for inspection upon request? Engine is malfunctioning, increase in oil consumption, MPG dropping, a ticking/knocking noise coming from the engine, and erratic engine behavior with random surges while driving to 6000+ RPM. Brought it into Kia 2x now for same issue and first time said nothing was wrong and second time I am now going through an oil consumption test. Vehicle is still unsafe to drive but they say this is the only option to do their test to move forward with my warranty with Kia. I am driving through mountain passes daily with this behavior and I worry if the engine blows I'll lose control of the vehicle and fall off the cliff. How was your safety or the safety of others put at risk? I am instructed to drive it still. Has the problem been reproduced or confirmed by a dealer or independent service center? The engine oil consumption test is happening now, I have driven 500 miles and the engine oil is low, pending to hear back from Kia on when they can get it in for next steps. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, just a Kia dealership (if that is the manufacturer then yes) Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No. And there is no warning lights for low engine oil. I have driven many times without oil and no warning that the oil was even low. The vehicle burns up oil fast.

I am reporting a dangerous engine failure involving sudden loss of power and complete engine shutdown. While traveling uphill on I-90 in Massachusetts, my 2017 Kia Sportage suddenly lost engine power and rapidly became unable to maintain speed. I first moved into the right lane due to the power loss, but then had to cross traffic at approximately 20 mph to reach a small emergency shoulder area on the left side of the highway, where the vehicle completely died. This created a serious highway safety hazard for me and other drivers. We were stranded in a highly dangerous location and required assistance from multiple Massachusetts State Troopers due to the unsafe roadside conditions. The vehicle was towed to a Kia dealership, where they diagnosed: spark plugs covered in oil, multiple cylinder misfires, compression loss in cylinder 3, burnt valve causing failure likely worn valve seals causing oil consumption. The dealership stated the engine had been burning/consuming oil and that the burnt valve caused the loss of compression and sudden breakdown. This vehicle uses the 2.4L Theta II GDI engine, which has a long history of engine failures, oil consumption complaints, stalling, and class-action litigation involving sudden engine failure and loss of power.

My 2017 Kia Sportage with approximately 98,000 miles suddenly started using oil at times. It would go for several trips with everything fine and then it would be a quart low. I continued to drive it and check the oil before every trip. At approximately 106,000 miles, I suddenly lost engine power, a small puff of black smoke from the exhaust, and the check engine light came on. I crippled it home after checking all fluids - they were fine. I trailered the car to my mechanic and after diagnosing it, he stated the #1 cylinder had no compression. I brought it home and checked online to find out that this seemed to be a common occurrence with the Sportage. To double check, I took the car to a second mechanic to get the same results except he provided more detail. Compression on #1 Cylinder 0, #2 was 140, #3 145, #4 140. He stated the compression should be above 175. My safety issue was I could have been stranded on I49 and if this had happened at night, I may not have been able to get it home. I took the vehicle to Crain Kia, Fayetteville, AR. when the first Check Engine Light came on and they stated it was shown as low engine oil even though it had oil in the engine and that it showed low compression on Cylinder 4. I now have a vehicle with 106,048 miles that without major engine repairs is worthless to me.

Kia Sportage has had serious oil consumption issues for 3 years. And recently is loosing pressure in cylinder 2 as a result of excessive carbon build up on valves and head from oil burning in the combustion chamber.

Catastrophic engine failure, no oil, over 3 qts low, oil light did not come on, 4 Cylinder had no compression. In summary: On [XXX] oil light came on, how? I just had oil change on 7/28/25. Stopped to check oil, it was dry. Bought 5Qts at WalMart, put 3 Qts in. Checked oil every day, started keeping 5Qt jug oil in car. 9/1/25 took in to have checked for oil leak/oil change, No leak detected. Continued checking oil consumption everyday, adding oil all the time... Purchased 5 Qts - 5 Times between August & November 2025. On 11/21/25 took to Auto Shop my MaxCare Extended Service Plan sent me to for a few minor checks, including to check again for oil leak. There was no leak found but they did need to replace valve cover gasket - Engine Valve Cover. Continued to check oil, added when low as needed. On [XXX] driving on highway, about 15 minutes at approx. 75-80 mph, started losing speed, had to really press on gas pedal to keep going, felt some vibration underneath engine maybe (?), engine light came on, I got off exit, went through intersection, car barely made it, pulled off on shoulder. Called for tow truck, it was cold, after waiting a while I turned car on to get some heat but the heat was not working. Auto Shop car was towed to had to add 3 qts of oil to do diag test. PO304cylinder 4 misfire, PO303cylinder 3 misfire... no compression on cylinder 4. No signs of visible oil leak(s). * Had car towed to Gerald Kia Dealer, Naperville, IL Their diagnostic test ONLY indicated that spark plugs need to be replaced and recommend that I get a 3 part carbon body cleaning, at my expense. I told the Service Tech I would be right up there to see manager. He told me to FIRST send him all my receipts for oil & oil changes, and he will see what he can do. didn't hear back. Went there in person 1/9/26. Manager told me that his tech "forgot" to do one test, i waited 1/2 hour, those results DID indicate engine needs to be replaced. But, Kia is not paying for it.....

October 2, 2025 no oil in engine. car has always had regular oil maintenance. Dealer put almost four quarts of oil in car to start an Oil Consumption Test of 1,000 miles. November 22, 2025 driving about 70 miles an hour, on the 241 Toll Road car loses powder, speed dropped to about 20 miles an hour. I was able to make it to the highway shoulder where the engine struggled to stay running. I cut the engine off and it would not start again. Had to be towed to Covina Kia. Still had over three hundred miles before the 1,000 mile test. Last oil change July 9, 2025 at Covina Kia. I bought my 2017 Kia Sportage in October 2016 brand new. I'm the only one to drive it. I have always taken it back to dealer for servicing. All my oil changes were done with the dealer and on time. I understand there is a class action lawsuit against kia for oil starvation and engines seizing, (theta II sc147). All indications suggests my engine also suffered the same manufacturer defect as claimed in the lawsuit. AND I WANT TO BE COMPENSATED KIA Manufacturer is aware of there engine problems and should be more proactive, before someone is killed

Car started having issues with retaining oil and was blowing oil out of the oil fil cap, oil changes were being performed every 3 weeks due to continued oil loss without cause. Car started shaking while driving on the highway, check engine light started flashing and car lost all power. Car was towed from highway to KIA authorized dealer where they performed a full engine replacement, replaced serpentine belt, oil filter and air filters. Picked up vehicle from dealership approx. 2 weeks later, engine was still blowing oil out of oil fill cap and entire vehicle smelled like used oil. Dealership also refilled engine with wrong type of oil upon replacement of engine. Car requires 5W-20, dealership put in 5W-30 instead of correct oil.

I have documented oil consumption issue since 65,000 miles. Every time I got an oil change after that, I would have very low oil. When I told Kia, they told me that the engine would have to "blow up" for anything to be done. This all occurred before my 100,000 mile powertrain was expired. On July 2, 2025, my car began shaking and jumping while I was driving and any time I had the brake on at a red light. I took it to Midas for a diagnostic test and they said that 3 out of the 4 cylinders were misfiring. They told me to take it immediately to Kia. When I took it, they said they would do a diagnostic test. They said that one of the cylinders were misfiring and that I would need a new engine. At this time I was at approximately 113,;000 miles. I opened a claim with Kia and for a month, the only correpondence I had with them was when I called either Kia Corporate or Kia service where my car was. They never helped me, only told me I could get a new car and they would give me "a deal". I finally got in touch with a local mechanic and he said he wanted to look at the car. When I went to Kia to pick it up, it would not start, even when one of their mechanics jumped it. The local mechanic towed it for me, but not before Kia made me pay over $400 to take a car that did not run. They would not give me the keys until I paid. The local mechanic found that I had a cracked spark plug and had my car running in a day. I am appalled at how I was treated and how Kia would not stand by their car and then tried to get me to buy a new one. My car was well taken care of and it should not have needed a new engine, had oil consumption problems or should have been sitting in service for a month. Something needs to be done so that this does not happen again. There is a Facebook page dedicated to Kia engines and the stories are very similar to mine. This is not right.

Burning oil. Having to put a quart of oil every 1-2weeks with less then 500 miles used. Local dealer won’t do anything about it.

January 9, 2025 I bought a new 2017 KIA Sportage from Bob Bell KIA-Glen Burnie July of 2017. All oil changes have been performed up-to-date and regularly as advised. When Bob Bell-Glen Burnie no longer serviced KIA, I started taking my vehicle to KIA-Eastern Avenue (Baltimore). The oil consumption issue started during the time I was taking my vehicle to KIA-Eastern Avenue for services. Throughout this entire process, I received mixed messages from KIA-Eastern Avenue, JBA KIA-Glen Burnie, and Johnson KIA-Annapolis about how often to change the oil. Depending on which Advisor at each dealership I spoke with – one would say change the oil every three thousand miles another would say every five thousand miles. As of late, one of the Advisors (Johnson KIA-Annapolis) even told me over the phone that I should change the oil every 2500 miles as that is what he does for his car – thankfully, I happen to be a customer that knows better than that. Unfortunately, his poor advice reminds me of the poor customer service dealing with KIA-Eastern Avenue, which is why I chose to deal no longer with them and take my vehicle to Johnson KIA-Annapolis with the hopes of getting better service. Advisor was kind enough to verify my information in Johnson KIA’s system and had to make a couple of corrections - one being my name misspelled and the other being someone entered into the system that I was not the original owner of my car when in fact I bought it off the Bob Bell KIA-Glen Burnie lot, brand new. In September of 2023, after my car went limp on the highway due to a knock engine sensor, I had my car towed to Johnson KIA-Annapolis (see Invoice XXX). They performed a BCT and decided that my car was one that did not fit the requirements for a new engine.
