2017 Kia Sportage

My car went into limp mode on the high way due to a faulty knock sensor. my car decelerated rapidly, which could have put me and others around me at risk. I had to repair this problem on my own even though other cars similar to my make and model have had the same issue.

The engine consumes a massive amount of oil to where I have to check my oil constantly and refill as often as weekly. This can pose a risk to myself and others due to the engine failing while I am driving. I am sure other issues can come from an engine running out of soil that I’m not aware of.

One day as I was turning at a green light the car completely stopped on me. I had to turn it off and then restart it and it worked fine. About a week later I had to drive to my cousin's house 45 minutes away and the car would not go, it acted like it was stalling and It didn't want to go over 2000RPMs and it was really sluggish like it didn't want to shift into the next gear. I finally got on the highway and it would not go past 60 miles an hour and then also if you try to drive it, it will slow down like its shutting off on you. I've had a new battery replaced, 4 new tires a windshield, and wipers replaced. I took the car to AutoZone and also to another guy and both of them used their computers and said that it's the engine and they called it rod knocking. I called customer service and they said yes their is a recall and that they would replace the engine. I tried to call kia in mesquite Texas because that is the closest one to me and I left a voicemail they did not call me back I am carless I'm a single disabled mother I need a working car.

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.

While driving on the interstate at highway speed with cruise control engaged, the engine suffered sudden catastrophic failure with absolutely no prior warning, warning lights, knocking, stalling, or other symptoms. The vehicle became inoperable immediately. The repair estimate is $6,500 for engine replacement. The vehicle is a 2017 Kia Sportage equipped with a Theta II 2.4L GDI engine, confirmed by service campaign SC340 on file with NHTSA. Two safety recalls remain incomplete on this vehicle: 21V137 and 22V703. The Knock Sensor Detection System software update campaign SC340 was never completed prior to my purchase of the vehicle in February 2024 from a used car dealer, despite being issued in July 2018. Kia Consumer Affairs indicated the claim would likely be denied due to the incomplete KSDS update, despite that update predating my ownership entirely. A dealer appointment had been scheduled for June 26, 2024 to address outstanding recalls prior to this failure occurring.

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 NHTSA 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.

Although there are no apparent signs of damage or impact, it seems that the airbag has been partially deployed. After seeking input from multiple individuals, they all agreed that this is probably a manufacturing defect. Unfortunately, when I contacted Kia, they let me know that they are unable to help me because the vehicle's warranty has expired. I have been a dedicated Kia customer for more than 15 years, having owned five different models throughout that period.

I own a 2017 Kia Sportage 2.4L (VIN: [XXX] ). In October of 2024 , the vehicle began making a loud engine knocking noise consistent with a known rod bearing failure. I immediately stopped driving and it has been in my garage to prevent further damage or safety risk. I contacted KIA America corporate twice 4/17/26 and was denied engine replacement twice. Kia stated I was not eligible for coverage under the engine defect settlement?KSDS update requirements. We are the second owner of the car having purchased it in 2020. I never received the letter about the knock sensor update. I did receive a recall in Dec 2026 a tow hitch harness and another in March 2026 for voluntary emissions campaign. I asked why I did not receive notification they said they most likely sent it to original owner they would not CK if received and then said the NHTSA sends those out and to contact you which is not the case they send them out. I have a 2.4L engine consistent with the defect causing sudden engine failure, fires and hazardous driving conditions. I was denied being able to file a report for not having the software update for the engine knocking (I never received) and for not services it with a KIA dealship I maintained my vehicle and have my documents.

Component Failure: Independent inspection confirmed a broken brake master cylinder mounting bracket and a missing AC compressor mounting bolt. Safety Risk: The broken brake bracket compromises the structural integrity of the braking system, posing a risk of brake failure while driving. The missing AC bolt creates a risk of the compressor becoming unseated, which could damage the serpentine belt and cause a sudden loss of power steering or engine cooling. Dealer Interaction: The selling dealer (Orr Nissan West) advertised the vehicle as "vetted" but has since ignored multiple formal requests for the pre-sale inspection records after these defects were discovered.

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.

The vehicle has had recurring drivability problems since at least June 2024, including repeated check engine light illumination and severe loss of acceleration. On 06/19/2024, dealership service records document that the check engine light was on and the vehicle would not accelerate past 40 mph, and the check engine light was flashing. More recently, while driving on the interstate at highway speed, the vehicle suddenly lost power and dropped speed, forcing me to pull over on the side of the road for safety. This created a dangerous situation and risk of collision. The problem continues despite multiple service visits. A dealership service visit on 06/05/2025 documents stored diagnostic trouble code P0420 (Catalyst System Efficiency Below Threshold), but the dealership stated no further repairs were recommended and no repair was performed. This issue is recurring and creates a serious safety hazard due to sudden loss of power while driving.

"I am reporting a catastrophic engine failure (rod knock/bearing failure) in my 2017 Kia Sportage, consistent with the Theta II GDI defect.

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 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.

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.

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.

*Component or System: Power window system / electrical system *What Happened? The manufacturer issued a recall for a defect in the power window system. When I brought my vehicle to the authorized service center, I was informed that the recall repair applies only to the front power windows, even though the same malfunction and defect are clearly present in the rear windows as well. The manufacturer’s refusal to include the rear windows leaves the defect only partially remedied, which could pose a continuing safety risk. This appears to be an incomplete or inadequate recall repair, as all four windows share the same design and failure pattern. I am requesting that NHTSA review whether the manufacturer’s limited repair scope meets federal recall requirements. *When Did This Happen? October 2025 *Has the Problem Been Reproduced or Confirmed by a Dealer or Independent Service Center? Yes – the dealership confirmed the issue with all four windows but stated that only the front windows are covered under the recall. *Has the Vehicle Been Inspected by the Manufacturer or Dealer? Yes – inspected at Nalley Kia 7849 Mall Pkwy, Stonecrest, GA 30038 *Were There Any Injuries, Fires, or Crashes? NO *Additional Details / Attachments-I can provide copies of the recall notice, service invoice, and correspondence with the dealership confirming the limited repair coverage upon request.

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.

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.
