KIA Complaints

While driving the car started to have the sensors for the adaptive cruise control, automatic emergency breaking, blind spot warning, forward collision warning, and rear cross traffic warning all came on. The rpm starting going crazy the car was shaking and struggling to start, the car was shifting weird causing the acceleration to be poor. This all happened while driving if we were on a busy road we would’ve gotten hit the car randomly started breaking and slowing down, this is dangerously and could cause serious injury and damages to the vehicle and others around it. This is a problem a lot of people have been complaining about and need to be fixed it’s not okay or safe to be driving a car with these issues especially when there is no warning it just breaks and shuts down no matter where you are or how fast you may be going.

I was driving on the freeway and the windshield spontaneously cracked. There were no cars even around me. My 2025 Telluride is brand new and has less than 5k miles on it…

My 2018 Kia Sportage (VIN: [XXX] ) triggered a check engine light and entered limp mode. Diagnostic scan revealed DTC code P1326, which is associated with the Knock Sensor Detection System (KSDS) and often linked to engine bearing failure in many affected Kia models. This happened at approximately 120,000 miles while driving under normal conditions. The car now runs in reduced power mode, making it unsafe for highway use or commuting. I contacted my local dealership, who confirmed no recall or campaign was active, despite this being a widely known and reported safety defect in Kia’s 2.4L GDI engines. I am requesting NHTSA to investigate this issue further, as many Kia and Hyundai vehicles with this engine have experienced sudden failures due to this defect. Kia should extend warranty support or issue a recall to prevent dangerous engine shutdowns. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While I was drive these warning lights came on as you in the picture there are no signs of a crash. I have took my car in for service at Kia of Bradley for them to reset my system on 7/01/2025 and they have came back on and they would not go off. I feel like this is a recall on my Kia Optima 2019.

Car erratically shifts and provides more power to vehicle when it is not necessary. It often shakes in between shifting.

Driving down highway, gas hand was on half a tank then all of a sudden gas hand drops to empty and light comes on, engine started sputtering. Heard a loud pop in the back seat looked back and back seat has popped up from base. Strong odor of gasoline poured into the car. Went to closest gas station to get off highway. Unable to put fuel into tank. Called Quality KIA of Greenwood they said get out of the car and do not drive it. Called for a tow, vehicle has been towed to Quality KIA of Greenwood.

In October 2024 we broke down on the highway outside of DesMoines, IA. The van slowed considerably in the midst of 11am traffic on I [XXX] from a lack of power, not from applying the brakes. Cars behind us had no warning, but no one hit us. The 4-way flashers and turn signals would not engage. There was no warning from the dashboard of a pending issue. Trent’s Garage in Clive, IA determined the main reason was an internal oil leak that damaged the alternator, which they replaced along with the right-side valve cover gasket. There was an earlier incident that I attributed to a service mistake. Shortly after Napleton Elmhurst Kia in IL serviced the vehicle in June 2023, it began to hesitate and become unresponsive while we were driving. There was no indication from the dash lights or from our garage floor that the engine was leaking any fluids or was low on oil, but I checked the oil at a suggestion from my wife. It barely registered on the dipstick. I added oil and the van ran fine. I now monitor the oil level regularly and add a quart of oil every 1000 miles. There is still no visible oil leak. Napleton Kia Service told me nothing could be done short of replacing the engine, and that I should change the oil more frequently (April 2025) than their original recommendation of every 5000 miles.

On 3 July 2025, while driving the car suddenly lost power and started smoking under the hood. I pulled over, exited the vehicle, and an engine fire started a minute later. The fire department put out the fire. The safety of myself and my child were at risk. We were driving at 40 miles per hour when the car lost power and caught fire. There were no warning lights. The car was towed to an independent repair shop to be evaluated, but results have not yet been gathered. There are known issues and recalls associated with 2014 Kia optima and with its engine losing power and catching fire, but my VIN was not included in the recalls when it should have been. This could have resulted in injury or the loss of life. At a minimum it has caused a loss of financial stability for my family due to Kia failing to produce and maintain safe vehicles.

Driving on the frwy when car started loosing power/acceleration, no warning lights or indicators on dashboard. Safely able to merge off the frwy. Turned off vehicle, engine would not turn back on. But all the dash lights came up as warning including engine light. Started to smell like burnt. Open the hood and it smelled like burning oil. Towed my vehicle & under the vehicle a pool of engine oil. Dealer confirmed engine seized. When repairs began water pump was damaged & engine mounts due to engine seizing.

When traveling at highway speeds the rear suspension is not capable of handling road imperfections. When a pot hole or other disturbance occurs, the rear end of the vehicle violently porpoises and swing back and forth. This is made even more obvious when taking a long sweeping curves at 55 plus. It causes the entire chassis to become very upset. I have never had a car do this.
