KIA Complaints

Rod went through the the back of the engine causing smoke and vehicle locked up.

*The vehicle cuts off randomly while driving without warning . *Error lights come on randomly on dash and states to shift to park. *Trouble starting the vehicle and putting in reverse. *There have been many random occurrences with this vehicle which began shortly after October 2025. * I have taken it to the dealership twice complaining g of the issues and the service department states "that they are not able to duplicate the issues and no errors are being see." * I fear for the safety of my family and I as issues have occurred in traffic posing a dangerous situation. I do not have means to obtain a rental or purchase another vehicle. So,this is the only vehicle available.

I purchased this car from a dealership. After getting home, I realized the rear safety head restraints were missing. After multiple attempts to contact and ask for this to be fixed, I don't get returned calls and have not received the replacement head restraints. I was NOT notified at the time of purchase these were missing. I will not let passengers sit in my rear seat without these safety headrests.

ICCU failure at 16k miles. The ICCU was replaced at the dealership on January, 29th of this year, so it is not available for inspection. The failure tripped a breaker at my home while it was charging possibly indicating a short circuit. The short circuit could have potentioally overheated and caught fire in my home. I took the vehicle to the dealership and they confirmed it was the ICCU and replaced it under warranty. I have a copy of the invoice received after the replacement was installed. I do not know what they did with the old ICCU after it was placed. There was no indication of pending failure that I noticed prior to this incident occuring.

I am submitting a safety complaint regarding a serious incident involving my 2025 Kia EV9. The vehicle was serviced on March 1 at World Kia in Joliet, Illinois. On April 4, only four days after that service, the vehicle experienced a sudden and unexpected ICCU failure while I was driving. During my normal travel, in active traffic and at speed, the vehicle abruptly entered limp mode and displayed multiple system warnings. This caused an immediate and significant reduction in power, creating a hazardous situation for myself and surrounding drivers. I was forced to maneuver the vehicle out of traffic while it was rapidly losing propulsion capability. The vehicle is currently at Berwyn Kia in Berwyn, Illinois for diagnosis and repair. I am reporting this incident due to the clear safety implications of a sudden loss of power during highway driving operation. A failure of this nature poses a risk of collision, especially in high-speed or congested traffic conditions. I am requesting that NHTSA review this issue as part of its ongoing monitoring of Kia/Hyundai/Genesis Integrated Charging Control Unit (ICCU) failures and related safety concerns. Thank you for your attention to this matter.

Safety recall letter dated 4/4/25 states the piston rings may have been manufactured incorrectly causing oil consumption resulting in loss of drive power and/or fire. Kia performed two 1000 mile oil level checks which indicated it was 2 quarts low both times!!! I have asked for a written document stating they are not going to fix the problem and why (because he did not have all his oil change records ) but they will not send one not will they answer my emails or phone calls!

I am submitting a complaint regarding my 2011 Kia Optima (VIN: [XXX] ), which is currently experiencing significant engine issues and is undrivable. This issue is currently being reviewed under Kia Case #XXX. This vehicle is part of the Theta II engine group that has been the subject of recalls, service campaigns, and extended warranty coverage due to known engine defects, including rod bearing failure and potential engine seizure. The vehicle has also received the Knock Sensor Detection System (KSDS) update associated with these known issues. My vehicle is currently at the dealership and has been there since March 10, 2026. It is not drivable, and I have been without transportation during this time. The dealership has diagnosed the issue as oil consumption; however, Kia has denied coverage, stating that oil consumption is not related to rod bearing failure. Kia has not confirmed whether a full internal engine inspection was performed to rule out rod bearing damage, nor have they confirmed that a Techline engineering review has been conducted. Given the known history of engine defects in this model, I am concerned that the current condition may be related to internal engine failure that has not been properly evaluated. Oil consumption can be a precursor or symptom of internal engine damage, and I do not believe the issue has been fully or adequately diagnosed. Additionally, my vehicle has an open safety recall related to potential engine compartment fire risk, which further raises concerns about the safety and reliability of this vehicle. I am requesting that this issue be reviewed as a potential safety-related defect, as the vehicle is undrivable and may be at risk for sudden engine failure or fire. I am also concerned that the manufacturer is relying solely on a dealership-level assessment without a thorough engineering evaluation of a known defect condition. Thank you for your review of this matter. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Was wondering why this vehicle isn't included in the fuel pump recall .There is hesitation, starves for fuel. All the symptoms, per mechanic, saying that is should be included!

2022 Kia Sorento. Dec 2024(previous owner incident) to new owner purchase May 2025- April 2026 vehicle keeps displaying all lights and warnings, loses acceleration & loss of throttle power while driving. High voltage code P0653 code displays. RPM’s will go up and down while vehicle is in park. Have had an active case open with Kia America Escalated case specialist since Nov 2025. Vehicle has been taken to two different Kia dealerships and has had this incident 7 times since May 2025 used purchase. A few different parts have been changed while working with a Kia America tech over a computer, yet it doesn’t fix the problem. It was reported in 2024 by the previous owner and the dealership could not find the source. It was never disclosed from the dealership prior to reselling. My problems started 3 weeks after owning the car. Less than 200 miles. I got in contact with previous owner, the vehicle kept going into limp mode while driving & the code would clear before she could get it to the shop & they couldn’t resolve it, so she traded it back in. 1st Incident: Dec 2, 2024 (previous owner) 2nd: June 6, 2025 3rd: July 19, 2025 4th: August 14, 205 5th: September 19,2025 Contacted Kia after and finally assigned a case officer Nov 10, 2025. Taken to shop Nov 11, 2025. 6th: Feb 22, 2026 7th: April 4, 2026 - going 75Mph on a highway and having to cross 4 lanes of traffic with no throttle power.

The contact owns a 2020 Kia Soul. The contact stated that while driving approximately 15 MPH, the engine started knocking on the passenger side of the vehicle underneath the hood. The contact accelerated to 45 MPH and continued driving. After refueling, while continuing to drive at 45 MPH, the vehicle suddenly lost engine power, and the vehicle started coasting. The vehicle was stopped, restarted, and the contact continued driving. A short while after restarting the vehicle, the failure reoccurred. The contact stopped the vehicle, waited, then restarted the vehicle a second time. The vehicle was driven to the destination. An image of an engine was displayed on the instrument panel, and the vehicle continued to make a knocking sound. The vehicle was towed to a certified mechanic, who diagnosed that the engine was failing and needed to be replaced. The certified mechanic informed the contact about NHTSA Campaign Number: 21V259000 (Engine); and associated the vehicle with the recall; however, the VIN was not included. The vehicle was not repaired. The vehicle was then towed to the dealer, who confirmed the diagnosis; however, the dealer had not repaired the vehicle. The manufacturer was informed of the failure. The manufacturer declined to provide the engine replacement under recall or warranty. The failure mileage was approximately 79,000.
