general problems of the 2017 Kia Motor Sportage - part 1

Car started making noise, slowed down. I stopped the vehicle immediately and parked on shoulder. Towed it to a mechanic shop and they said the engine stopped. It needs an engine replacement.

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.

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.

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.

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.

The catalytic converter in the kia. We were driving to texas to take my kids out for Mini vacation and it’s cut off right in the middle of the highway. My car was running just fine everything was fix properly. Can you check in the catalytic converter and see if it safely issue.

Car shut off middle of driving. Mechanic said engine is seized, and no oil in engine. Car has always had regular oil maintenance. There is a class action lawsuit against kia for oil starvation and engines seizing, (theta ii sc147). Last oil change was ~4,500 miles ago. All indications suggests my engine also suffered the same manufacturer defect as claimed in the lawsuit. 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.

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.

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.

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. ".

See attached document for complaint.

On October 16, 2025 my car lost ability to accelerate while driving on highway. Just as the car was losing motive power the engine light came on. Car was then towed to a mechanic. After looking at the car the mechanic reported that the engine had seized and I would need a new engine. The mechanic was able to get the engine moving. The week before I had put oil in the car as I noticed it was going through oil faster.

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.

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.

Car starting shaking violently while on the highway. Daughter pulled over and parked car on side of road. Had to have car towed as it would not restart. Engine failure.

Blown engine p1236 knock sensor circuit.

Engine light came on flashing on the dash. Went to o’reily auto shop to get it checked and their scanner discovered p1326 code, “knocking sensor” and oil light came on and flashing as well. The motor oil was replaced about a month ago. Checked the oil dip stick and it was below the first dot.

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.

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] . Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

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.

Oil change completed on 6/19/2025 noticed oil leaking 3-4 days after change. Performance plus, came to my work and inspected oil leakage. They stated the leak was coming from the oil pressure switch. I had the engine recall completed less than a year ago. Is this something that's still under warranty?.

The contact owns a 2017 kia Sportage. The contact stated that while driving approximately 45 - 50 mph, the vehicle started to decelerate unintendedly. The contact depressed the accelerator pedal; however, the pedal went to the floorboard, and the vehicle failed to accelerate as needed. The contact attempted to depress the brake pedal; however, the brakes failed to stop the vehicle. The contact activated the hazard light and was able to coast to the side of the road and noticed smoke coming from underneath the hood of the vehicle with a burning odor. The contact turned off the vehicle and had the vehicle towed to a nearby mechanic. The mechanic determined that the engine had failed and referred the contact to the dealer for assistance. The vehicle was towed to the dealer, and it was determined that the engine needed to be replaced. The contact found information on NHTSA campaign number: 17v224000 (engine and engine cooling) online; however, after discussions with the dealer, it was decided that the contact had to provide maintenance receipts before any engine replacement could be finalized. The vehicle was not repaired. The manufacturer was informed of the failure, and a case was opened. The failure mileage was approximately 88,000.

The car is going through oil at a ridiculous rate. I have checked and it is not leaking. It is causing poor acceleration and driving performance. I make sure there is also oil in there but I should not have to do it as often as I do.

This placed me and other drivers at serious risk, especially since it happened on the interstate and I was unable to maneuver or accelerate safely. On [xxx], the engine overheated in severe, bumper to bumper traffic. The owner’s safety was put at risk due to the high volume of traffic and little options to pull over. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? yes, the engine failure has been confirmed by both an independent mechanic and a kia dealership. They diagnosed the engine as seized and non-repairable without a full engine replacement. Engine was replaced by kia on March 26-28, 2025 and returned to the owner on March 28,2025. At the dealership's recommendation the owner replaced all the hoses and belts. Owner was assured all fluids had been refilled and engine repair was complete.

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.

My kia engine is blown. Kia engine rod bearing failed due to metal shavings when they made the engine. They didn't blow the shavings out. They are stating it's my fault do to lack of maintenance records they will not replace my engine. This is there loophole in the lawsuit to deny people of there claims.

Kia when producing the engine left metal shavings that they didn't blow out. This lead them to put a ksds sensor in. The sensor just let's you know of a catastrophic engine failure. It did not fix the problem. This is leading to engine failures and kia finding loop holes to not replace them. This is kia neglect not the consumer. They are finding ways to blame the consumer for maintenance records to deny an engine replacement.
