KIA Complaints

Listing as all 3. ICCU/fuse went out, car decelerated to 45 MPH max and flashed a warning to pull over. The bottom left battery indicator for the 12v battery also changed to red, indicating it was not regaining power from the main EV battery. Currently in shop hoping to get part in soon

I am submitting this revised complaint to correct a prior report that was not accurately documented during a phone submission. Vehicle: 2025 Kia Sorento (259 miles at purchase) Within approximately two months of ownership (~3,000 miles), the vehicle began experiencing serious safety-related issues, including intermittent stalling, braking problems, and electrical malfunctions. Symptoms include: •Vehicle stalled and failed to restart, leaving me stranded •Radio/display screen went blank •Heating/climate system became nonfunctional •Vehicle would not shift into neutral •Persistent burning odor inside and outside the vehicle These issues raise concern about a potential fire risk. In May 2025, the vehicle was inspected by two separate dealerships, both of which reported no issues. The condition worsened, resulting in a complete failure requiring towing. A dealership later identified “electrical issues,” but key symptoms were not documented. A second dealership has since stated the vehicle is operating normally; I disagree, as I believe the root cause has not been resolved. Issues began at ~3,000 miles, with major failure at ~22,000 miles. I have contacted Kia and requested a buyback due to repeated failures and safety concerns. This request was denied twice; a goodwill credit was offered but not accepted. This complaint is submitted to report ongoing safety defects involving stalling, braking, electrical failure, and a potential fire risk.

The contact’s mother owns a 2017 Kia Sportage. While the contact's mother was driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The contact's mother noticed an abnormal odor and an abnormal ticking sound coming from the vehicle. Additionally, the check engine warning light was illuminated. The vehicle was taken to the Auto Zone and connected to a diagnostic machine, and DTC: P0128, P1326, and P0014 were retrieved. The contact's mother received notification of NHTSA Campaign Number: 22V703000 (Trailer Hitches). The contact was unsure if the failure was associated with the unrepaired recall. The manufacturer was not made aware of the failure. The failure mileage was approximately 141,000.

My 2021 Kia Soul experienced repeated overheating despite replacement of major cooling system components including the thermostat and water pump. The vehicle continued to overheat and was later diagnosed by a Kia dealership with engine damage requiring full engine replacement. This failure occurred around 105,000 miles. The symptoms and failure pattern are consistent with known issues affecting similar Kia engines, yet my VIN is not included in any recall. I am concerned this represents a broader defect that may not be fully captured in current recalls.

While driving my KIA Optima on the interstate the rear subframe suffered catastrophic structural failure, resulting in the steering wheel going out of alignment, the rear passenger side wheel tilting with the bottom of the tire being far out compared to the top. This resulted in the rear of the vehicle swaying side to side and being difficult to maintain in a straight path. This vehicle was previously serviced under KIA Campaign SC141 (internal subframe corrosion) at Griffin KIA on April 27, 2017. Despite this safety remedy being performed the subframe rotted through and snapped. This is a remedy failure. The anti-corrosion was applied by the manufacturer failed to prevent the exact structural failure it was designed to mitigate. I have physical evidence (Repair Order #92144) proving the remedy was performed and photographic/video evidence of the subsequent structural break. The manufacturer (KIA) has denied assistance, claiming the failure is "unrelated" to the corrosion campaign despite the part being the exact component covered by the campaign." SC141 involved the inject of wax into the metal components of the subframe of the vehicle and was KIA's response to the NHSTA's concerns about the metal components of their vehicles being unable to withstand salt in the Rust Belt states. The campaign only was for the vehicles in the rust belt states. KIA was very aware this was a safety issue and attempted to avoid a recall by issuing this campaign. The campaign failed and as a result my life was put at risk. I asked KIA for a good will repair of the rusted subframe but they refuse indicating the believe the part that clearly broke due to rust is unrelated to the safety campaign. Several of their employees stated it was very clear the part broke due to rust with one indicating he had a list of rusted parts needing replaced. I'd like the NHTSA to review this failed campaign and ensure the safety of all vehicles relying on this failed safety measure.

This is a follow up to the above referenced case #XXX This has been reported to the Attorney General’s Office and they have requested that I send along the following information to your office. I purchased a 2022 Kia Telluride approximately 2 years ago. At the time, I also purchased a 100,000 mile extended warranty from KIA. The cost was $3,200. Since owning the vehicle, I have had a problem with the heating system. I contacted the Balise KIA dealership, West Springfield, MA where the car was purchased to have the heating system checked out. It is still not working correctly! The most recent attempt by KIA to fix the heat was 2/2/26 and was not successful. KIA stated “there is no fix”. Please refer to invoice #XXX. Driving a car with little or no heat is unacceptable. I was told that if there ever was a fix, the warranty would cover it. I was also charged a diagnostic fee of $159.95 which I paid, but did not agree with. This fee is charged if a customer decides against having the work done, which I agree with, but in this case, I wanted the work done, but they couldn’t do the work because there is no fix. If there was a fix, the warranty would have covered it. I feel this problem greatly reduces the value of this vehicle and some kind of resolution should be reached. I am [XXX] old and driving a vehicle that has little or no heat is not only uncomfortable, but unhealthy. I’ve been paying close attention to the heat when I’m in the car. It seems to work ok above 30 degrees, but below 30 degrees it doesn’t work properly. Thank you for your time and I await your response [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This 2024 Kia soul, 2 issues 1. the instrument cluster does not show, when turning the vehicle on the instrument cluster is blank, meaning I cannot see the speed limit, how much fuel or use any adaptive features, braking, lane departure, cruise control, etc ****this creates a dangerous situation and I do not believe the car is safe to drive**** I see there is a recall for this issue on 2023 models Kia 23V298000 Kia SC270 2. Intermittent window issues with the automatic windows, when opening from the driver side the windows will not come back up, have to pull over and turn vehicle on and off and /or try to close the windows from each door individually I called to report this to Kia at [XXX] and asked them to repair both and they were not much help, I asked this be reported and am not confident the person will actually do so They did tell me there were issues already noted which I requested be raised to a technical service bulletin or a recall and extend the warranty for all affected vehicles thank you INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving on the service road of the freeway, driving approximately 40 mph when my main screen started flashing warnings. I was only able to catch 2 before the screen shut off. One was saying front collision sensors not working and the other said side sensors not working then the screen where the radio was went black. Then my brake pedal locked up, the car lost all power steering. The car started to just roll and I was able to pull into a side parking lot and the car died. I was not able to start the vehicle and called roadside assistance and had my vehicle towed to the car dealership. This was during rush hour traffic with multiple vehicles in the road. I was terrified as my vehicle was slowly starting to stop moving and there were multiple cars surrounding me while I lost all brake function and power steering. At the time of this report, the service department at my dealership was closed and will call them in the morning. The tow truck left my vehicle there as it is inoperable. From the time I noticed the warnings on the screen to when my vehicle came to a complete stop was about 2 minutes.

On the motor, when off for more than a certain time prolonged, when is a cold start motor make a noise like it doesn’t have oil in it since new I let the dealer know but they say it’s normal and I don’t believe so. Also, the transmission have a problem since New it shifted weird sometimes, and the dealer says it’s normal

I was on the on-ramp getting on the highway and whenever I started to increase speed and try to get over into the next lane, I noticed the car all of a sudden jumped a little bit and then it started consistently jumping in the check engine light was flashing, and I couldn’t keep the car over what ended up being 50 mph anytime I tried to go over 50 mph. The car jumped in was shaking pretty pretty aggressively I was able to finally make it to a gas station at the very next highway stop and after I shut the car off and turn it back on it seems like it was OK, but I’m still very scared to drive it. I then took it to the dealership to have them check for any store or pending codes because after we had stopped and turned the car back on it no longer had the check engine light on, and the dealership was not able to locate any stored codes in the system to see what it happened nor were they able to replicate the issue that we had found. Is a rec out on my vehicle, but no remedy is available and notices will not be sent for another month and a half at this point I am extremely uncomfortable driving my vehicle as I have young children and anything with a fire hazard is not safe.
