Kia Sportage check engine light comes on

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.

I purchased my 2022 Kia Sportage in 2021 from Kia Store East here in [XXX]. On Oct. 9th, for the first time in five years, I saw an engine light on in my car and the car started shaking. The dealer could not get me in until XXX. I received a call on Oct. 22nd stating that the vehicle has a cylinder 1 misfire. The dealership scoped the cylder one and found a hole in the exhaust valve. The fix for a five year old car with 105K miles? A long engine block replacement to the tune of $9,723. There is an issue with these Kia engines that extends beyond the current settlement. I was on the highway when this happened. I could have easily been in an accident on the expressway. The oil in the engine was almost empty (no oil light) and the engine failing (this was the first time I saw an engine light).

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

My 2016 Kia Sportage LX experienced a catastrophic engine seizure on September 9, 2026, at 91,249 miles. My son was returning home on I-95 South in Florida. After exiting at Sample Road and traveling west near Seabra Foods at approximately 40 mph, he first noticed unusual engine noises at an estimated 91,245 miles. He pulled over, immediately called me, and sent a video recording of the noise. I advised him to proceed to Bisbee Auto & Tires, an independent repair facility. The engine completely seized directly in front of its service entrance at 91,249 miles. Most concerning, my son reported NO dashboard warning lights, including the check engine light, before the engine seized, despite Kia's service records confirming that the Knock Sensor Detection System (KSDS) update had been completed before the failure. KSDS is intended to detect certain vibrations associated with connecting rod bearing damage. I request investigation into why no warning appeared, whether KSDS operated correctly, whether diagnostic code P1326 was recorded, and the actual engine failure mechanism. My son regularly drives on I-95 at 65 mph. Had the engine seized in highway traffic, sudden loss of propulsion could have caused a serious collision, injuries, or death. Bisbee Auto & Tires informed us about potential lifetime engine warranty coverage and directed us to Kia rather than charging approximately $6,000 for an engine replacement. Kia replaced the engine under warranty in September 2026. On October 13, 2026, Kia Corporate confirmed that the replacement was the same engine type but could not identify engineering improvements, revised bearings, or whether it was new or remanufactured. I request the federal safety agency investigate this engine seizure, the absence of KSDS warnings despite the completed update, similar incidents, and whether additional safety measures are warranted. Service records and video evidence are available upon request.

My daughter's 2020 Kia Sportage S was purchased September 22, 2025 from a Nissan Dealership with 96,574 miles on it. It dove great. She used it less than 20 miles per day on residential streets to get to and from work and to church on Sunday. It was not used for interstate or freeway driving. By June of 2026, we noticed that it was requiring more oil between oil changes. The oil level was checked at least once every other week to see if more oil needed to be added. We were adding about a quart of oil every two to three weeks although there was no evidence of excess smoke coming from the exhaust. Then on my daughter's way to work on August 13, 2026 she experienced a sudden shaking of the car and the engine light came on. She immediately pulled over and turned off the engine. We were out of town at the time so my son came to see what was wrong with the car. He checked the engine oil first and it was within the right level. The car was limped to the local Kia dealership to trouble shoot it and they said that there was evidence of rod/bearing failure in one cylinder that was causing the shaking. There is no fix for it other than to replace the engine at a dealer discounted price of $6,600. Kia corporate is offering a $1,000 credit toward the repair and the dealership is contributing $4,040 to the engine replacement. The car has 103,510 miles on it now. The Theta II 2.4 engine had an engine settlement that covered model years through 2019. Ours is a 2020 that was built in May 2019 and has the same engine that failed under the engine settlement. But ours is not covered. We are still in the process of working with the local Kia Dealership and Kia Corporate to make it right on an engine that clearly has known problems causing premature engine failures. I have owned or recommended to family members to buy Kia/Hyundai vehicles and between all of us we have had 13 Kia/Hyundai vehicles. This may be the last Kia/Hyundai vehicle that we own...

The Kia never showed an engine light error or gave a code stating there was a problem. We Change the oil every 3000 miles. There was no oil on the dip stick and the oil was extremely low. The engine seized up today.
