2023 Kia Sportage: check engine light

Filed Nov 2, 2026 · IL

I am filing a safety complaint regarding our 2023 Kia Sportage, VIN [XXX], with approximately 51,331 miles. The vehicle began experiencing shaking and vibration while driving at speeds below approximately 40 mph. The check-engine warning light also illuminated. This raised serious concerns about the vehicle's reliability and safe operation, particularly because my daughter regularly drives this vehicle to and from school. I am concerned about the possibility of an unexpected loss of power, breakdown, or other mechanical failure while she is driving. On XXX, the vehicle was inspected at Napleton's River Oaks Kia in [XXX]. According to Repair Order #XXX, diagnostic testing confirmed engine misfires in cylinders 2 and 4. The technician swapped ignition coils, performed additional testing, and documented that the misfires returned. Carbon buildup was identified on the cylinder 2 spark plug, and all four spark plugs were replaced at a cost of $406.17. Although the shaking and vibration stopped following this repair, the underlying cause of the misfires remains a concern. I subsequently learned about an investigation involving alleged defective fuel injectors in certain 2023 Kia Sportage vehicles and Kia Technical Service Bulletin FUE068. I do not know whether our vehicle has a defective fuel injector, and the dealership's invoice does not indicate whether the injectors were tested. I am requesting that the federal safety agency review this incident to determine whether the engine misfires could be associated with a broader vehicle safety defect. The vehicle has been inspected by an authorized Kia dealership, and the repair documentation is available upon request. The original spark plugs' availability for inspection is UNKNOWN. My primary concern is the safety of my daughter and other motorists should a similar malfunction occur again.

02/2025 Engine light on - dealership said it was a coolant sensor has not repaired 2026 I was driving my car as normal went to a store and whole driving I went to try to use my turn signals and nothing wouldn’t light up wouldn’t do anything, I attempted to use my emergency lights also were not working I had to pull over I got off another store went back in car and they started working fine as if nothing accured. This has happened multiple times many calls to dealership that will only look at it if I leave my car but no loaner car unless I pay ridiculous amount. The car has touch screen climant control / radio volume that goes in and out, touch screen will not respond this is hazardous when driving I cannot signal other drivers or put my emergency lights on. I’ve reached out multiple times to dealership and no one seems to care but this is a problem I could cause an accident I’m in fear something else will happen

Purchased the vehicle 2nd hand January 29th 2025. Since then she has been in and out of multiple shops including Kia. Check engine light, loss of power on fwy, shifting/brake changes from a stop. From jerking, lunging, studder, taking off fast, not wanting to go at all. I was on these dips that I encounter almost daily and the collision warning went off. There wasnt anything in front of me. 2 weeks later I was cut off and had to swerve to avoid. Collision warning DID NOT go off. Driving on the fwy and the gas pedal pulled away from my foot as if it was accelerating. Kia has done a hard carbon, changed all fuel injectors. Last time they stated there was a factory defect with the rotors, changed all 4 rotors. Still she drives like this. Carmax, Kia and Daniels Tires NO ONE can tell me what is wrong! I have driven a 2024 same make and model and the car drove beautifully. Something is wrong with my particular vehicle. This is becoming frustrating. Please help. I drive often, I hike a lot. We are always on winding roads. I can't afford to sell it as I still owe. I love the vehicle, aside from this, like I'm just waiting for disaster to occur. Miles started at 14.5k and it's now 33k. Speeds have been anywhere from a complete stop to go and fwy speeds of 55 to 80.

The issue appears to involve the CVT (Continuously Variable Transmission) system or the transmission fluid/lubricant pump. The vehicle jerks or hesitates when accelerating from a stop, as if struggling to shift properly. The check engine light comes on repeatedly. This issue is ongoing, and the vehicle is available for inspection upon request. The jerking and hesitation when trying to drive, especially from a stop or when merging into traffic, poses a safety risk to myself and others. The delayed or unpredictable response could easily lead to an accident in high-traffic areas, intersections, or when making turns. Yes. The issue has been observed multiple times. The check engine light has returned even after replacing the O2 sensors, and a trusted mechanic believes the problem may be transmission-related. However, the Kia dealership claims there are no active recalls tied to my VIN, even though publicly available information lists powertrain- and fluid pump-related recalls for my vehicle's year and model. The vehicle has not yet been inspected by Kia corporate. I reached out to the local dealer, who denied any applicable recall. I am submitting this complaint in hopes of an official review and inspection by the manufacturer or the federal safety agency to determine if the issue qualifies for safety recall intervention. Yes. The check engine light first appeared months ago, which led to replacement of the O2 sensors. Shortly after the replacement, the light returned, and the car began jerking while trying to drive or accelerate from a stop. These symptoms have persisted and appear to be worsening.

Engine Stalling Multiple Times while in Drive. After vehicle stalls, Engine Shuts off, multiple lights start flashing and beeping and Message States- 'Engine Off! Shift to P or N then start engine.' Engine will reengage after following display instructions. This creates a safety risk to driver and others behind driver when error occurs. 2 weeks prior to first failure, Engine light appeared, but was not flashing. Kia informed, but could not schedule for service for 14 days. Dates of Occurrence: 5/17/2023 ( 2 times), 7/28/2023 ( 3 times), 8/23/2023 (1 time) Vehicle with Kia Dealer for repair 5/17 to 5/29, 7/28 to 8/18, and 8/23 to present. No current ETA for repairs. None of the repairs has corrected issue.

Vehicle first felt like the tire was flat when turning. After parking and restarting the vehicle the vehicle seemed to hesitate to stay started. The check engine light came on the next day. After taking the vehicle in they said the injector was bad. Replacing it did not fix the problem. I am not waiting on approval to replace the engine at 20,000 miles.

One week after buying the brand new 2023 Kia Sportage, 6 warning signs popped up on the screen. They were to "Check the Forward Collision System," "Check the Bind Spot System," and 4 more of the safety features. In addition, the Check Engine light turning on, other warning signs were also highlighted in orange. Finally, when trying to move the car, I was not able to get the gear out of Park. This happened multiple times over 12 hours.
