2017 Kia Sportage fuel system problems

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 safety is put at risk. My car has stalled two different times on the highway. I was able to get it off the road after restarting the vehicle and coasting out. The engine was worked out by Kia of Mission Viejo. They stated it was not due to Rod bearing, although I was told on a separate occasion that there was metal in my oil in the same scenario then when they submitted the video to Kia, they said they only saw the burnt valve my check engine light has went on a total of three times I’ve had the same exact work done three additional times as well as the knock sensor having to be replaced because it went off and burned out due to what happened on the highway. My car is part of the theta engine issue with Kia

I own a 2017 Kia Sportage, and I recently experienced a malfunction indicator engine light turning on. Upon diagnosis by Kia Russ Darrow at Odana Rd Madison, WI , the vehicle displayed DTC P001000 – ‘A (Intake)’ Camshaft Position Actuator Circuit (Bank 1). They have noticed oil leakage around the E-CVVT motor plug area. It pointed to camshaft position sensor malfunction and Kia service say what the vehicle needs is a CVVT cover and seals/gaskets relating to the variable valve timing on the camshaft as it’s throwing the camshaft sensor circuit “high” voltage Kia has issued Technical Service Bulletin (TSB) SA305, which acknowledges a similar problem in earlier production models of the same vehicle (built from December 10, 2015 – September 12, 2016). However, my vehicle was manufactured in January 2017, and Kia has not yet included it in the affected range. Despite this, I am experiencing the exact same issue outlined in the TSB. This failure poses a potential safety risk because it can affect engine performance and reliability. If left unaddressed, it could lead to unexpected engine stalling, loss of power while driving, or further engine damage, creating a hazardous situation. I have not yet received confirmation from Kia regarding an official recall or warranty extension for my vehicle, but the symptoms are identical to those covered under SA305. The issue has been reproduced and confirmed by a mechanic, and I am currently in the process of contacting Kia for further inspection and assistance. There were no prior warning messages, aside from the Check Engine Light (MIL) illuminating when the problem first occurred. This complaint is being submitted to request an investigation into whether this defect extends beyond the current TSB range and to determine if additional 2017 Sportage models should be included in a service action or recall to prevent safety risks. The affected component is available for inspection upon request.

Component/System Failure: Multiple issues have occurred with the vehicle, starting with the windows not functioning shortly after purchase. The most severe issue occurred when the engine failed completely, causing it to shut down in the middle of a busy intersection during rush hour. This left the car non-functional and posed significant safety risks. In addition, the fuel system consistently becomes contaminated, despite following proper fuel maintenance practices like using high-quality fuel and regularly using a system cleaner. Is the Component Available for Inspection Upon Request? It's important to confirm whether the damaged components (like the engine or fuel system parts) are available for inspection by a dealer, an independent service center, or the manufacturer. If you haven't already, request documentation or access to the faulty components so that experts can inspect them and provide insight into what went wrong. Safety Risk: The engine failure in the middle of a busy intersection during rush hour was a major safety risk, not just to you but to other drivers as well. An unexpected engine failure at such a critical time could have led to accidents, making it clear that there’s a serious safety concern that needs addressing immediately. Even if the fuel system issue isn’t as immediately dangerous, it still affects the vehicle’s performance and longevity. Problem Reproduced or Confirmed by Dealer or Service Center? Has a dealer or an independent service center been able to reproduce or confirm these problems? If not, it may help to schedule an appointment for a detailed inspection. If the dealer or service center has acknowledged the issues, ensure you have written confirmation or a detailed report. Inspection by Manufacturer, Police, or Insurance? Kia dealership finally took it in broke down the engine and wasn't fully clear what is causing the problem, my extended warranty sent a inspection but is taking way more time then what should be allowed

first owner 2017 Kia Sportage SX (NOTE SX specifically) AWD 2.0L Turbo Gas Direct Injection (4-cyl engine) (no recalls found) - EXCESSIVE Oil Consumption since early/mid 2023 and continues still today, [XXX]. We lose over 1 quart of oil every 1,000 miles, did not discover this until an oil change in early 2023 how low our oil was. No leaks then, no leaks now, oil maintenance performed, we have meticulous records and have been to the #1 Cochran Robinson Township Kia dealership where they have perform Kias required Oil Consumption Test that we've paid for. 1st set of test failed each time, dealership performed deep clean, and since there was only 3/4 quart loss, Kia had no further responsibilities. too busy with our small business over the holidays, started Oil Consumption test, again [XXX]. Every single time we hit 1,000 miles (monthly) we are down over 1+ quarts of oil, with no leaks anywhere. Added 40 ounces of oil (I have photos) a few days before we decided to get the Oil Consumption test again. PLS NOTE: There are quite a few MODELS and ENGINES listed in recalls or perhaps lawsuits for excessive oil consumption, our SX model 2.0L Turbo Gas Direct Injection (4 cyl) specifically is not. Over the past 7 months, we have lost over 8 quarts of oil, and have had 2 maintenance oil changes in between, part of normal maintenance. Looking online there are thousands of posts regarding Kia Excessive Oil Consumption, Kia states losing 1 quart every 1,000 miles is acceptable? How can this not cause a hazard to us drivers, engine could blow due to oil going somewhere or into the environment, etc? IF you require all of the service records for the oil changes, etc. I have them all. Thank You Sincerely [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) The contact stated the vehicle is continuing to show Excessive Oil Consumption while required to go through this KIA test again, (first in 2023, now this 2nd set of the same tests). Further stating that numerous owners having
