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.

"I am reporting a catastrophic engine failure (rod knock/bearing failure) in my 2017 Kia Sportage, consistent with the Theta II GDI defect. The failure caused a sudden loss of motive power while in traffic, creating a significant safety risk. Furthermore, I am reporting Bill Dodge Kia (Westbrook, ME) for safety negligence. On September 26, 2023 (at 83,611 miles), this vehicle was in their service bay for brake work. Despite the vehicle being under an active HECU Fire Risk Recall (SC206) and requiring the KSDS Product Improvement Campaign, the dealership failed to perform these safety updates or disclose them to me. When confronted, dealership management (Alex Pinto, Bob Colton, and Patrick Demers) explicitly stated it was 'not their responsibility' to inform customers of known defects or active recalls. This practice left me driving a vehicle with a known fire risk and a documented engine defect for over two years without my knowledge, ultimately leading to the current engine failure."

On 1/10 about 1.5 hour driving out of town later engine started idling low. Pulled over, replaced spark plugs and engine coil and still idling rough. Took vehicle for diagnostics of a broken head in the valve. I drive a 2.4L engine 2017 Kia Sportage LX AWD. only 114K miles. Quoted thousands and thousands, more than care worth to repair.

On 11/21/2025, while operating my vehicle, I experienced a critical engine failure. The engine failed a compression test, with readings as follows: Cylinder 1: 125 PSI Cylinder 2: 60 PSI Cylinder 3: 25 PSI Cylinder 4: 3 PSI As a result, the engine had no compression in multiple cylinders, preventing the vehicle from starting. The vehicle exhibited [smoke, stalling, or other observable symptoms]. This failure appears consistent with known issues in the Theta 2 GDI engines, including risk of engine failure or fire. I had not received notification of any required software updates or recalls relevant to this issue. Despite multiple attempts to resolve this with the dealer, including [dates of service attempts], the dealer refused to cover a replacement engine under warranty. Impact on Safety: The sudden engine failure rendered the vehicle inoperable and posed a significant safety risk due to the potential for stalling or fire while driving. Additional Notes: I am submitting this report to request that the NHTSA investigate this potential safety defect.

On November 2, while driving my 10-year-old son to a soccer game, the vehicle suffered a sudden loss of power at road speed. The vehicle's failure to provide a "limp-home mode" or any sensor warnings prior to stalling created a significant life-safety risk for my son and me as we had to coast across traffic to a safe location where the car stalled. -??No Warning Indicators: There were no prior "Check Engine" lights, oil pressure warnings, or temperature fluctuations. -??Hazardous Failure Mode: The vehicle stalled completely in active traffic. I was forced to perform an emergency maneuver, coasting across lanes of traffic to reach a safe shoulder. -??Outcome: The vehicle was towed to Ourisman Kia of Bethesda, where service technicians diagnosed "severe internal engine failure."

My wife was driving home from work on 10-15-2025 when the car started to lose power and started shaking, vibrating really bad. She got off the exit and at the red light and it died. She called me crying and scared. She started the car back up to try to get the car home and she said the car is vibrating and shaking really bad and I-??m so scared and it died again in traffic. I told her to pull over and I would come get her and she did make it home. I look at the car and found it had a misfire on cylinder 2. Cylinder 2 had NO COMPRESSION. I did take it to Kia and they confirmed the diagnosis. Here is where the problem lies. The technician that scanned my car purposely miss diagnosed it. He wrote it only had burnt valves and cylinder. He never said anything about the hole in my piston. He took a picture of it and it has a hole on top. He said the car was drivable; are you kidding me. When you start the car the voice comes over the speakers and says the computer has detected a major engine problem. My cars vin # confirms that it qualifies for the class actions settlement because of the engine that is in the car. They are known to fail because of excessive oil use, starvation of oil, bad piston rings, bad rod bearings. We have been without her car since this happened. Kia said the car was drivable and I can promise you it is not. This car is not safe at all to drive. It loss all power in traffic and it kept dying.

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

My Kia engine has failed and Kia is refusing to submit or honor my engine replacement claim under the known engine defect class action/recall. The dealer told me that the claim cannot be submitted because a prior owner did not receive the KSDS (Knock Sensor Detection System) software update. Kia then changed their reasoning and stated the engine failure was -??for another reason, -?? but still refuses to provide documentation or allow the claim to be processed. I was left without a vehicle, charged excessive diagnostic fees, and stranded in dangerous winter weather conditions (around -30?F wind chills). The dealership refuses to send the engine claim to Kia, stating the -??missing KSDS update-?? as the justification, even though the engine failure was unrelated to that software and the recall states that Kia must prove the update-??s absence caused the failure before denying coverage. Kia-??s refusal has resulted in an unexpected repair estimate of approximately $6,000, no loaner vehicle, and severe hardship. Their actions appear to violate recall obligations and consumer safety protections, as I am being denied a known-defective engine replacement due to a prior owner-??s failure to complete a software update. I am requesting investigation and intervention, as Kia is not honoring the recall process or the class action settlement requirements.

Balise Kia in West Springfield MA refuses to do the inspection of the engine without proof of every single oil change since i purchased the vehicle in 2016, which is an impossible request. Corporate also stated that it is the dealership's discretion to demand oil receipts, even though I offered to print credit card statements instead, and I purchased a car fax report that has them listed beginning in 2019, but unfortunately none reported before then. I provided them with receipts of no oil changes missed since 2024. still denied the inspection. there were no warning lights prior to the engine seizing.

While driving on the parkway with my child and younger cousin in the vehicle, the car unexpectedly began to decelerate without warning. I safely pulled over to the side of the road and turned the vehicle off. When attempting to restart it, the engine would not crank or turn on. Moments later, smoke began to appear from under the hood. Additionally, the engine, battery, and oil warning lights illuminated on the dashboard. This incident created a dangerous situation and raised serious safety concerns regarding the reliability of the vehicle.

I was sold a Kia sportage 2017 in February. I was told this vehicle has no after market parts. After my vehicle catching fire and seizing on me June 26th of this year so 4 months after buying the vehicle. It was discovered that an after market starter is indeed in this vehicle with loose wiring. I could have lost my life on my way home. The dealership has been nothing but a pain since this experience I have encountered. My insurance was involved but was told I need to bring this issue to Kia. Contacted Demontround Kia multiple times was never helped once. Contacted Kia customer care. I have a claims agent who has been no help whatsoever. I was told to get my car towed to West side Kia, which they have been rude from the start and have been no help. They actually want me to come out out of pocket for engine related damages that was not my fault given that I-??ve only had the car for four months before the engine seized on me and caught fire on my way home from work. When I told a server worker at Westside that I don-??t believe that I should be paying out of pocket he had somebody else contact me. They emailed me that same day to call them as soon as I can. I called them immediately after I got the email and didn-??t even receive an answer. Nora call back and I called multiple times for the next consecutive days and I finally get an email saying sorry they were moving buildings that is very unprofessional. There was no point to email me originally to tell me to contact you then.

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.

We had to take the car to a mechanic to have the engine replaced because it started making a loud noise and then stopped running. They advised us that because it has less than 150,000 miles, it should be covered by KIA. We spoke to KIA and they told us that because we missed 2 recalls that we were never notified about it would not be covered. If the recalls would have been done, they would cover the damages. We purchased the car a couple of years ago from my sister in law who got it when my father in law passed away in 2019. I checked with her and she never received the recalls and we never received them. Therefore, since neither of us knew about the recalls they were not done. I spoke to someone at NHTSA and they advised me to file a complaint. They don't have records of where the recalls were mailed. We are having to pay $4500 out of pocket due to this issue. Please advise if there is something that you can do to help get KIA to reimburse us or the damages that should be covered by them. My cell # is [XXX].
