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.
ENGINE,FUEL/PROPULSION SYSTEM07/06/2026
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.

The contact's mother owned a 2017 Kia Sportage. The contact stated that while her brother was driving at an undisclosed speed, the vehicle lost motive power. The contact's brother parked the vehicle, rolled down the window, and became aware that there was smoke coming from under the hood before the vehicle caught on fire. The contact's brother exited the vehicle and ran away from the vehicle. The contact's brother called the contact and the police about the fire. The Police, bomb squad, and firefighters arrived at the scene. The firefighters extinguished the fire. The Police, bomb squad, and fire department reports were filed. The contact's brother received medical treatment for a severe asthma attack. The vehicle was towed to a tow yard, but the insurance company had not yet declared the vehicle a total loss because the vehicle only had liability coverage. Upon investigation, the contact's brother discovered that the VIN was included in NHTSA Campaign Number: 22V703000 (Trailer Hitches); however, the contact's mother had not received a recall notification. The manufacturer was not made aware of the failure. The failure mileage was approximately 75,000.
STEERING,WHEELS,SERVICE BRAKES06/16/2026
Unexplainable issues with brake pedal. Makes noise inside cabin that sounds like a squeaky door. Happens when depressing brake pedal at 20mph or less and does not in reverse. Pedal feels odd, somewhat pulsating and when turning, I believe, the front passenger wheel pulls. Steering wheel is noticeably affected also, noting a jerking sensation. Several mechanics are unable to identify the issue. There are no dash lights on.
VEHICLE SPEED CONTROL,ENGINE06/16/2026
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.

Window regulator failure - power window could not be rolled up. Had to be replaced.
ENGINE06/16/2026
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.
POWER TRAIN,ENGINE05/18/2026
I experienced engine failure and the dealership, corporation and warranty are refusing to replace the engine. My engine falls under an engine settlement. The denial states the corporation will not approve because i do not have a system update. The system update was issued while in the dealer’s inventory, part of the Certified Pre Owned inspection, it is required that the dealer updates all recalls & product improvements before certification.
