KIA Complaints

The engine has structural manufacturer defect causing extreme internal engine oil consumption with zero external leaks, creating a severe risk of sudden oil starvation catastrophic mechanical engine failure. The severe oil consumption problem was confirmed by a certified national corporate service center (Firestone Auto Care). An intermittent P0420 catalytic converter warning is actively appearing on the dashboard, which is a documented consequence of internal engine oil burning. When attempting to get this mechanical defect diagnosed and repaired under the class-action parameters, manufacturer dealerships (Findlay Kia and Jim Marsh Kia) declined to schedule the mandatory manufacturer diagnostic testing, preventing a known vehicle defect from being resolved.

My 2024 Kia K5's infotainment screen went completely pitch black, disabling the backup camera now creating an active safety hazard.

After sitting in the driveway came out to a crack across half of the passenger side front side window. In the process of getting the window replaced. Crack originated from underneath the door trim. Window could shatter while driving if not noticed.

What component or system failed: The hybrid battery management system (BMS) failed while driving. The dashboard displayed a Battery Management System error along with a lane assist warning. The vehicle then completely lost propulsion, no response from the accelerator pedal, while on an incline, causing the vehicle to roll backward down the hill. The vehicle is currently at the dealership (Kia Temecula) and available for inspection but no one has reached out to me for days. Safety risk: The vehicle lost all forward propulsion while in motion on a hill and began rolling backward, with no ability to accelerate or control forward movement. This posed a serious risk of collision or rollaway accident. I shut the vehicle off and restarted it, which restored partial function for approximately 1 minute before the same failure recurred. Has the problem been reproduced/confirmed: Not yet confirmed by dealer — vehicle was towed to Kia Temecula on 7/12/26 via Kia roadside assistance and is awaiting diagnostic inspection. Dealer scheduling offered August 4, 2026 as the earliest availability, which is unacceptable given the safety nature of the defect. Inspected by manufacturer, police, insurance, etc.: Not yet inspected. Vehicle towed to authorized Kia dealer; diagnostic pending. Warning lamps/messages prior to failure: Yes — Battery Management System error and lane assist function warning appeared on the dash immediately before the vehicle lost propulsion. No prior symptoms were noted before this incident.

The contact owns a 2012 Kia Soul. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. No warning lights were illuminated. The vehicle was driven to the residence. The contact stated that the following day, while attempting to start the vehicle, the vehicle started, and the check engine warning light was off. The vehicle was taken to the dealer, where the contact was informed that the recall repair failure code was not illuminated. In addition, the contact was informed that the failure was not covered under a recall. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact received a recall notification, NHTSA Campaign Number: 19V120000 (Engine, Engine and Engine Cooling). The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 156,310.

NHTSA Bulletin TSB BOD300 My KIA 2016 Optima Turbo has all four windows impacted by the defective gear. I've opened a case with KIA and it's case number 25563361. None of my windows roll up or down. This presents several very serious safety issues. The dealer has had my vehicle for over 2 weeks. Why has KIA not been forced to issue a recall on these defective gears?

Vehicle Component Affected: Electrical System / HVAC / Blower Motor Resistor Incident Description: While operating my 2023 Kia Sorento, the HVAC system suddenly suffered a complete failure, causing all airflow to cease instantly. A subsequent professional diagnostic inspection by an authorized Kia dealership revealed that the contacts at the blower motor resistor were severely burnt, causing the blower motor relay to burn out. This failure presents two critical safety and fire hazards: Fire Risk: The physical burning and overheating of electrical components and wiring within the dashboard assembly create an active fire hazard in the passenger cabin. Loss of Visibility: The sudden, complete loss of the climate control system severely compromises passenger safety by preventing the vehicle from defogging or defrosting the windshield during inclement weather, presenting an immediate crash hazard. This exact failure mechanism matches the description of Kia Safety Recall SC351 (NHTSA Campaign 25V649) word-for-word. However, Kia has stated that my specific VIN is excluded from the current recall population. Because this identical safety defect is actively manifesting outside of Kia's restricted recall range, I am requesting that the NHTSA investigate an expansion of SC351 to include all affected 2023 Kia Sorento vehicles to mitigate the risk of electrical fires and sudden visibility loss. 06/29/26 Experienced symptoms Inspected and diagnosed on 07/01/26 at JT Kia (Killian Road) Columbia, South Carolina

About six months ago, I lost the heated steering wheel functionality in my steering wheel, then from there, I slowly lost functionality like cruise control, and the most recent now my airbag and horn do not work. If you press on the horn, it is silent, and the airbag light has been illuminated consistently for the last couple of months. I had this issue diagnosed and it came up with the codes of B1346. And B1481. After some research, these issues are the result of a bad clock, spring and cause the airbag and horn not to work. Additionally, this issue is known to this model the 2011 Kia Optima, and has been recalled in most production cases of this vehicle, but my vehicle is not included. I received a quote for $876 from a dealership to get this corrected, but it should be included in the recall.

NHTSA Complaint Description — Kia Sportage Engine Stall While driving my 2020 Kia Sportage in mid-June 2026 on I-45 in Houston, TX, the vehicle suddenly stalled while I was driving, with no warning lights, messages, or symptoms beforehand. This created a dangerous situation because I was in active highway traffic and had to pull over immediately. My oil change was due on 06/02/2026, but even between 06/15–06/20, the vehicle should still have had oil. A car does not lose all oil in two weeks under normal conditions. The sudden stall and lack of oil indicate a mechanical defect, not a maintenance issue. I received a Kia notice around December 2025 or early January 2026 stating that my vehicle’s year and model could be eligible for an engine defect inspection. The letter explained that even if my VIN does not show up in their system, the model/year is still included. My vehicle is showing the same symptoms described in the defect notice, including unexpected stalling and oil loss. The problem has not yet been inspected or confirmed by the dealer, but the incident clearly shows a serious safety risk. My vehicle is available for inspection upon request.

The Kia Driver Assistance Warning, Showing a Coffee Pot, and Warning "Driver needs to Take Break" goes off constantly. Sometimes starts within 5 minutes of driving and goes off constantly for every 3 minutes . Dealer says it is a KIA problem and can not do anything. This constant warning is a Safety Hazard because it takes the Drivers Attention off his Driving with the constant Bells going off. It is a 2023 Kia Telluride and previous models you could turn off this Warning but NOT in 2023 according to dealer and KIA will not repair or turn off. This is a Safety Hazard.
